ii. Acid Deposition and Forest Ecosystem Impacts
    Current understanding of the effects of acid deposition on forest 
ecosystems focuses on the effects of ecological processes affecting 
plant uptake, retention, and cycling of nutrients within forest 
ecosystems. Recent studies indicate that acid deposition is at least 
partially responsible for decreases in base cations (calcium, 
magnesium, potassium, and others) from soils in the northeastern and 
southeastern United States. Losses of calcium from forest soils and 
forested watersheds have now been documented as a sensitive early 
indicator of soil response to acid deposition for a wide range of 
forest soils in the United States.
    In red spruce stands, a clear link exists between acid deposition, 
calcium supply, and sensitivity to abiotic stress. Red spruce uptake 
and retention of calcium is impacted by acid deposition in two main 
ways: Leaching of important stores of calcium from needles and 
decreased root uptake of calcium due to calcium depletion from the soil 
and aluminum mobilization. These changes increase the sensitivity of 
red spruce to winter injuries under normal winter conditions in the 
Northeast, result in the loss of needles, slow tree growth, and impair 
the overall health and productivity of forest ecosystems in many areas 
of the eastern United States. In addition, recent studies of sugar 
maple decline in the Northeast demonstrate a link between low base 
cation availability, high levels of aluminum and manganese in the soil, 
and increased levels of tree mortality due to native defoliating 
insects.
    Although sulfate is the primary cause of base cation leaching, 
nitrate is a significant contributor in watersheds that are nearly 
nitrogen saturated. Base cation depletion is a cause for concern 
because of the role these ions play in surface water acid 
neutralization and their importance as essential nutrients for tree 
growth (calcium, magnesium and potassium).
    This regulatory action will decrease acid deposition in the 
transport region and is likely to have positive effects on the health 
and productivity of forest systems in the region.
iii. Coastal Ecosystems
    Since 1990, a large amount of research has been conducted on the 
impact of nitrogen deposition to coastal waters. Nitrogen is often the 
limiting nutrient in coastal ecosystems. Increasing the levels of 
nitrogen in coastal waters can cause significant changes to those 
ecosystems. In recent decades, human activities have accelerated 
nitrogen nutrient inputs, causing excessive growth of algae and leading 
to degraded water quality and associated impairments of estuarine and 
coastal resources.
    Atmospheric deposition of nitrogen is a significant source of 
nitrogen to many estuaries. The amount of nitrogen entering estuaries 
due to atmospheric deposition varies widely, depending on the size and 
location of the estuarine watershed and other sources of nitrogen in 
the watershed. There are a few estuaries where atmospheric deposition 
of nitrogen contributes well over 40 percent of the total nitrogen 
load; however, in most estuaries for which estimates exist, the 
contribution from atmospheric deposition ranges from 15-30 percent. The 
area of the country with the highest air deposition rates (30 percent 
deposition rates) includes many estuaries along the northeast seaboard 
from Massachusetts to the Chesapeake Bay and along the central Gulf of 
Mexico coast.
    In 1999, National Oceanic and Atmospheric Administration (NOAA) 
published the results of a 5-year national assessment of the severity 
and extent of estuarine eutrophication. An estuary is defined as the 
inland arm of the sea that meets the mouth of a river. The 138 
estuaries characterized in the study represent more than 90 percent of 
total estuarine water surface area and the total number of U.S. 
estuaries. The study found that estuaries with moderate to high 
eutrophication represented 65 percent of the estuarine surface area.
    Eutrophication is of particular concern in coastal areas with poor 
or stratified circulation patterns, such as the Chesapeake Bay, Long 
Island Sound, and the Gulf of Mexico. In such areas, the 
``overproduced'' algae tends to sink to the bottom and decay, using all 
or most of the available oxygen and thereby reducing or eliminating 
populations of bottom-feeder fish and shellfish, distorting the normal 
population balance between different aquatic organisms, and in extreme 
cases, causing dramatic fish kills. Severe and persistent 
eutrophication often directly impacts human activities. For example, 
fishery resource losses can be caused directly by fish kills associated 
with low dissolved oxygen and toxic blooms. Declines in tourism occur 
when low dissolved oxygen causes noxious smells and floating mats of 
algal blooms create unfavorable aesthetic conditions. Risks to human 
health increase when the toxins from algal blooms accumulate in edible 
fish and shellfish, and when toxins become airborne, causing 
respiratory problems due to inhalation. According to the NOAA report, 
more than half of the nation's estuaries have moderate to high 
expressions of at least one of these symptoms'an indication that 
eutrophication is well developed in more than half of U.S. estuaries.
    This rule is anticipated to reduce nitrogen deposition in the CAIR 
region. Thus, reductions in the levels of nitrogen deposition will have 
a positive impact upon current eutrophic conditions in estuaries and 
coastal areas in the region. While we are unable to monetize the 
benefits of such reductions, the Chesapeake Bay Program estimated the 
reduced mass of delivered nitrogen loads likely to result from the 
CAIR, based upon the CAIR proposal deposition estimates published in 
January 2004. Atmospheric deposition of nitrogen accounts for a 
significant portion of the nitrogen loads to the Chesapeake with 28 
percent of the nitrogen loads from the watershed coming from air 
deposition. Based upon the CAIR proposal, nitrogen deposition rates 
published in the January 2004 proposal, the Chesapeake Bay Program 
finds that the CAIR will likely reduce the nitrogen loads to the Bay by 
10 million pounds per year by 2010.\178\ These substantial nitrogen 
load reductions more than fulfill the EPA's commitment to reduce 
atmospheric deposition delivered to the Chesapeake Bay by 8 million pounds.

b. Are There Health or Welfare Disbenefits of the CAIR That Have Not 
Been Quantified?
    In contrast to the additional benefits of the rule discussed above, 
it is also possible that this rule will result in disbenefits in some 
areas of the region. Current levels of nitrogen deposition in these 
areas may provide passive fertilization for forest and terrestrial 
ecosystems where nutrients are a limiting factor and for some croplands.
    The effects of ozone and PM on radiative transfer in the atmosphere 
can also lead to effects of uncertain magnitude and direction on the 
penetration of ultraviolet light and climate. Ground level ozone makes 
up a small percentage of total atmospheric ozone (including the 
stratospheric layer) that attenuates penetration of ultraviolet--b 
(UVb) radiation to the ground. The EPA's past evaluation of the 
information indicates that potential disbenefits would be small, 
variable, and with too many uncertainties to attempt quantification of 
relatively

[[Page 25312]]

small changes in average ozone levels over the course of a year (EPA, 
2005a). The EPA's most recent provisional assessment of the currently 
available information indicates that potential but unquantifiable 
benefits may also arise from ozone-related attenuation of UVb radiation 
(EPA, 2005b). Sulfate and nitrate particles also scatter UVb, which can 
decrease exposure of horizontal surfaces to UVb, but increase exposure 
of vertical surfaces. In this case as well, both the magnitude and 
direction of the effect of reductions in sulfate and nitrate particles 
are too uncertain to quantify (EPA, 2004). Ozone is a greenhouse gas, 
and sulfates and nitrates can reduce the amount of solar radiation 
reaching the earth, but EPA believes that we are unable to quantify any 
net climate-related disbenefit or benefit associated with the combined 
ozone and PM reductions in this rule.

Notes:
\a\ In addition to primary economic endpoints, there are a number of
  biological responses that have been associated with ozone health
  effects including increased airway responsiveness to stimuli,
  inflamation in the lung, acute inflammation and respiratory cell
  damage, and increased susceptibility to respiratory infection. The
  public health impact of these biological responses may be partly
  represented by our quantified endpoints.
\b\ Premature mortality associated with ozone is not currently included
  in the primary analysis. Recent evidence suggests that short-term
  exposures to ozone may have a significant effect on daily mortality
  rates, independent of exposure to PM. EPA is currently conducting a
  series of meta-analyses of the ozone mortality epidemiology
  literature. EPA will consider including ozone mortality in primary
  benefits analyses once a peer reviewed methodology is available.
\c\ In addition to primary economic endpoints, there are a number of
  biological responses that have been associated with PM health effects
  including morphological changes and altered host defense mechanisms.
  The public health impact of these biological responses may be partly
  represented by our quantified endpoints.
\d\ While some of the effects of short term exposures are likely to be
  captured in the estimates, there may be premature mortality due to
  short term exposure to PM not captured in the cohort study upon which
  the primary analysis is based.
\e\ May result in benefits or disbenefits.
\f\ These are potential effects as the literature is insufficient.

B. Paperwork Reduction Act

    In compliance with the Paperwork Reduction Act (44 U.S.C. 3501 et 
seq.), EPA submitted a proposed Information Collection Request (ICR) 
(EPA ICR number 2512.01) to the OMB for review and approval on July 19, 
2004 (FR 42720-42722). The ICR describes the nature of the information 
collection and its estimated burden and cost associated with the final 
rule. In cases where information is already collected by a related 
program, the ICR takes into account only the additional burden. This 
situation arises in States that are also subject to requirements of the 
Consolidated Emissions Reporting Rule (EPA ICR number 0916.10; OMB 
control number 2060-0088) or for sources that are subject to the Acid 
Rain Program (EPA ICR number 1633.13; OMB control number 2060-0258) or 
NOX SIP Call (EPA ICR number 1857.03; OMB number 2060-0445) 
requirements.
    The EPA solicited comments on specific aspects of the information 
collection. The purpose of the ICR is to estimate the anticipated 
monitoring, reporting, and recordkeeping burden estimates and 
associated costs for States, local governments, and sources that are 
expected to result from the CAIR.
    The recordkeeping and reporting burden to sources resulting from 
States choosing to participate in a regional cap and trade program are 
expected to be less than $42 million annually at the time the monitors 
are implemented. This estimate includes the annualized cost of 
installing and operating appropriate SO2 and NOX 
emissions monitoring equipment to measure and report the total 
emissions of these pollutants from affected EGUs serving generators 
greater than 25 megawatt electrical. The burden to State and local air 
agencies includes any necessary SIP revisions, performing monitoring 
certification, and fulfilling audit responsibilities.
    In accordance with the Paperwork Reduction Act, on July 19, 2004, 
an ICR was made available to the public for comment. The 60-day comment 
period expired September 19, 2004 with no public comments received 
specific to the ICR.

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. Sec.  601 et seq.)(RFA), 
as amended by the Small Business Regulatory Enforcement Fairness Act 
(Pub. L. 104-121)(SBREFA), provides that whenever an agency is required 
to publish a general notice of rulemaking, it must prepare and make 
available an initial regulatory flexibility analysis, unless it 
certifies that the rule, if promulgated, will not have ``a significant 
economic impact on a substantial number of small entities.'' 5 U.S.C. 
605(b). Small entities include small businesses, small organizations, 
and small governmental jurisdictions.
    For purposes of assessing the impacts of today's rule on small 
entities, small entity is defined as: (1) A small business that is 
identified by the North American Industry Classification System (NAICS) 
Code, as defined by the Small Business Administration (SBA); (2) a 
small governmental jurisdiction that is a government of a city, county, 
town, school district or special district with a population of less 
than 50,000; and (3) a small organization that is any not-for-profit 
enterprise which is independently owned and operated and is not 
dominant in its field. Table X-5 lists entities potentially impacted by 
this rule with applicable NAICS code.

\1\ North American Industry Classification System.
\2\ Federal, State, or local government-owned and operated
  establishments are classified according to the activity in which they
  are engaged.

    According to the SBA size standards for NAICS code 221112 
Utilities-Fossil Fuel Electric Power Generation, a firm is small if, 
including its affiliates, it is primarily engaged in the generation, 
transmission, and or distribution of electric energy for sale and its 
total electric output for the preceding fiscal year did not exceed 4 
million megawatt hours.
    Courts have interpreted the RFA to require a regulatory flexibility 
analysis only when small entities will be subject to the requirements 
of the rule. See Michigan v. EPA, 213 F.3d 663, 668-69 (DC Cir., 2000), 
cert. den. 121 S.Ct. 225, 149 L.Ed.2d 135 (2001).
    This rule would not establish requirements applicable to small 
entities. Instead, it would require States to develop, adopt, and 
submit SIP revisions that would achieve the necessary SO2 
and NOX emissions reductions, and would leave to the States 
the task of determining how to obtain those reductions, including which 
entities to regulate. Moreover, because affected States would have 
discretion to choose the sources to regulate and how much emissions 
reductions each selected source would have to achieve, EPA could not 
predict the effect of the rule on small entities. Although not required 
by the RFA, the Agency has conducted a small business analysis.
    Overall, about 445 MW of total small entity capacity, or 1.0 
percent of total small entity capacity in the CAIR region, is projected 
to be uneconomic to maintain under the CAIR relative to the base case. 
In practice, units projected to be uneconomic to maintain may be 
``mothballed,'' retired, or kept in service to ensure transmission 
reliability in certain parts of the grid. Our IPM modeling is unable to 
distinguish between these potential outcomes.
    The EPA modeling identified 264 small entities within the CAIR 
region based upon the definition of small entity outlined above. From 
this analysis, EPA excluded 189 small entities that were not projected 
to have at least one unit with a generating capacity of 25 MW or great 
operating in the base case. Thus, we found that 75 small entities may 
potentially be affected by the CAIR. Of these 75 small entities, 28 may 
experience compliance costs in excess of one percent of revenues in 
2010, and 46 may in 2015, based on the Agency's assumptions of how the 
affected States implement control measures to meet their emissions 
budgets as set forth in this rulemaking. Potentially affected small 
entities experiencing compliance costs in excess of 1 percent of 
revenues have

[[Page 25314]]

some potential for significant impact resulting from implementation of 
the CAIR. However, it is the Agency's position that because none of the 
affected entities currently operate in a competitive market 
environment, they should be able to pass the costs of complying with 
the CAIR on to rate-payers. Moreover, the decision to include only 
units greater than 25 MW in size exempts 185 small entities that would 
otherwise be potentially affected by the CAIR.
    Two other points should be considered when evaluating the impact of 
the CAIR, specifically, and cap and trade programs more generally, on 
small entities. First, under the CAIR, the cap and trade program is 
designed such that States determine how NOX allowances are 
to be allocated across units. A State that wishes to mitigate the 
impact of the rule on small entities might choose to allocate 
NOX allowances in a manner that is favorable to small 
entities. Finally, the use of cap and trade in general will limit 
impacts on small entities relative to a less flexible command-and-
control program.

D. Unfunded Mandates Reform Act

    Title II of the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-
4) (UMRA), establishes requirements for Federal agencies to assess the 
effects of their regulatory actions on State, local, and Tribal 
governments and the private sector. Under section 202 of the UMRA, 2 
U.S.C. 1532, EPA generally must prepare a written statement, including 
a cost-benefit analysis, for any proposed or final rule that ``includes 
any Federal mandate that may result in the expenditure by State, local, 
and Tribal governments, in the aggregate, or by the private sector, of 
$100,000,000 or more * * * in any one year.'' A ``Federal mandate'' is 
defined under section 421(6), 2 U.S.C. 658(6), to include a ``Federal 
intergovernmental mandate'' and a ``Federal private sector mandate.'' A 
``Federal intergovernmental mandate,'' in turn, is defined to include a 
regulation that ``would impose an enforceable duty upon State, Local, 
or Tribal governments,'' section 421(5)(A)(i), 2 U.S.C. 658(5)(A)(i), 
except for, among other things, a duty that is ``a condition of Federal 
assistance,'' section 421(5)(A)(i)(I). A ``Federal private sector 
mandate'' includes a regulation that ``would impose an enforceable duty 
upon the private sector,'' with certain exceptions, section 421(7)(A), 
2 U.S.C. 658(7)(A).
    Before promulgating an EPA rule for which a written statement is 
needed under section 202 of the UMRA, section 205, 2 U.S.C. 1535, of 
the UMRA generally requires EPA to identify and consider a reasonable 
number of regulatory alternatives and adopt the least costly, most 
cost-effective, or least burdensome alternative that achieves the 
objectives of the rule.
    The EPA prepared a written statement for the final rule consistent 
with the requirements of section 202 of the UMRA. Furthermore, as EPA 
stated in the rule, EPA is not directly establishing any regulatory 
requirements that may significantly or uniquely affect small 
governments, including Tribal governments. Thus, EPA is not obligated 
to develop under section 203 of the UMRA a small government agency 
plan. Furthermore, in a manner consistent with the intergovernmental 
consultation provisions of section 204 of the UMRA, EPA carried out 
consultations with the governmental entities affected by this rule.
    For several reasons, however, EPA is not reaching a final 
conclusion as to the applicability of the requirements of UMRA to this 
rulemaking action. First, it is questionable whether a requirement to 
submit a SIP revision would constitute a Federal mandate in any case. 
The obligation for a State to revise its SIP that arises out of section 
110(a) of the CAA is not legally enforceable by a court of law, and at 
most is a condition for continued receipt of highway funds. Therefore, 
it is possible to view an action requiring such a submittal as not 
creating any enforceable duty within the meaning of section 
421(5)(9a)(I) of UMRA (2 U.S.C. 658 (a)(I)). Even if it did, the duty 
could be viewed as falling within the exception for a condition of 
Federal assistance under section 421(5)(a)(i)(I) of UMRA (2 U.S.C. 
658(5)(a)(i)(I)).
    As noted earlier, however, notwithstanding these issues, EPA 
prepared for the final rule the statement that would be required by 
UMRA if its statutory provisions applied, and EPA has consulted with 
governmental entities as would be required by UMRA. Consequently, it is 
not necessary for EPA to reach a conclusion as to the applicability of 
the UMRA requirements.
    The EPA conducted an analysis of the economic impacts anticipated 
from the CAIR for government-owned entities. The modeling conducted 
using the IPM projects that about 340 MW of municipality-owned capacity 
(about 0.4 percent of all subdivision, State and municipality capacity 
in the CAIR region) would be uneconomic to maintain under the CAIR, 
beyond what is projected in the base case. In practice, however, the 
units projected to be uneconomic to maintain may be `mothballed,' 
retired, or kept in service to ensure transmission reliability in 
certain parts of the grid. For the most part, these units are small and 
infrequently used generating units that are dispersed throughout the 
CAIR region.
    The EPA modeling identified 265 State or municipally-owned 
entities, as well as subdivisions, within the CAIR region. The EPA 
excluded from the analysis government-owned entities that were not 
projected to have at least one unit with generating capacity of 25 MW 
or greater in the base case. Thus, we excluded 184 entities from the 
analysis. We found that 81 government entities will be potentially 
affected by CAIR. Of the 81 government entities, 20 may experience 
compliance costs in excess of 1 percent of revenues in 2010, and 39 may 
in 2015, based on our assumptions of how the affected States implement 
control measures to meet their emissions budgets as set forth in this 
rulemaking.
    Government entities projected to experience compliance costs in 
excess of 1 percent of revenues have some potential for significant 
impact resulting from implementation of the CAIR. However, as noted 
above, it is EPA's position that because these government entities can 
pass on their costs of compliance to rate-payers, they will not be 
significantly impacted. Furthermore, the decision to include only units 
greater than 25 MW in size exempts 179 government entities that would 
otherwise be potentially affected by the CAIR.
    The above points aside, potentially adverse impacts of the CAIR on 
State and municipality-owned entities could be limited by the fact that 
the cap and trade program is designed such that States determine how 
NOX allowances are to be allocated across units. A State 
that wishes to mitigate the impact of the rule on State or 
municipality-owned entities might choose to allocate NOX 
allowances in a manner that is favorable to these entities. Finally, 
the use of cap and trade in general will limit impacts on entities 
owned by small governments relative to a less flexible command-and-
control program.

E. Executive Order 13132: Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999), requires EPA to develop an accountable process to ensure 
``meaningful and timely input by State and local officials in the 
development of regulatory policies that have federalism implications.'' 
``Policies that have federalism implications'' is defined in the 
Executive Order to include

[[Page 25315]]

regulations that have ``substantial direct effects on the States, on 
the relationship between the national government and the States, or on 
the distribution of power and responsibilities among the various levels 
of government.''
    This rule does not have federalism implications. It will not have 
substantial direct effects on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government, as 
specified in Executive Order 13132. The CAA establishes the 
relationship between the Federal Government and the States, and this 
rule does not impact that relationship. Thus, Executive Order 13132 
does not apply to this rule. In the spirit of Executive Order 13132, 
and consistent with EPA policy to promote communications between EPA 
and State and local governments, EPA specifically solicited comment on 
this rule from State and local officials.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    Executive Order 13175, entitled ``Consultation and Coordination 
with Indian Tribal Governments'' (59 FR 22951, November 9, 2000), 
requires EPA to develop an accountable process to ensure ``meaningful 
and timely input by Tribal officials in the development of regulatory 
policies that have Tribal implications.'' This rule does not have 
``Tribal implications'' as specified in Executive Order 13175.
    This rule addresses transport of pollution that are precurors for 
ozone and PM2.5. The CAA provides for States and Tribes to 
develop plans to regulate emissions of air pollutants within their 
jurisdictions. The regulations clarify the statutory obligations of 
States and Tribes that develop plans to implement this rule. The Tribal 
Authority Rule (TAR) give Tribes the opportunity to develop and 
implement CAA programs, but it leaves to the discretion of the Tribe 
whether to develop these programs and which programs, or appropriate 
elements of a program, the Tribe will adopt.
    This rule does not have Tribal implications as defined by Executive 
Order 13175. It does not have a substantial direct effect on one or 
more Indian Tribes, because no Tribe has implemented a federally-
enforceable air quality management program under the CAA at this time. 
Furthermore, this rule does not affect the relationship or distribution 
of power and responsibilities between the Federal Government and Indian 
Tribes. The CAA and the TAR establish the relationship of the Federal 
Government and Tribes in developing plans to attain the NAAQS, and this 
rule does nothing to modify that relationship. Because this rule does 
not have Tribal implications, Executive Order 13175 does not apply.
    If one assumes a Tribe is implementing a Tribal Implementation 
Plan, today's rule could have implications for that Tribe, but it would 
not impose substantial direct costs upon the Tribe, nor preempt Tribal 
law. As provided above, EPA has estimated that the total annual private 
costs for the rule for the CAIR region as implemented by State, local, 
and Tribal governments is approximately $2.4 billion in 2010 and $3.6 
billion in 2015 (1999$). There are currently very few emissions sources 
in Indian country that could be affected by this rule and the 
percentage of Tribal land that will be impacted is very small. For 
Tribes that choose to regulate sources in Indian country, the costs 
would be attributed to inspecting regulated facilities and enforcing 
adopted regulations.
    Although Executive Order 13175 does not apply to this rule, EPA 
consulted with Tribal officials in developing this rule. The EPA has 
encouraged Tribal input at an early stage. Also, EPA held periodic 
meetings with the States and the Tribes during the technical 
development of this rule. Three meetings were held with the Crow Tribe, 
where the Tribe expressed concerns about potential impacts of the rule 
on their coal mine operations. In addition, EPA held three calls with 
Tribal environmental professionals to address concerns specific to the 
Tribes. These discussions have given EPA valuable information about 
Tribal concerns regarding the development of this rule. The EPA has 
provided briefings for Tribal representatives and the newly formed 
National Tribal Air Association (NTAA), and other national Tribal 
forums. Input from Tribal representatives has been taken into 
consideration in development of this rule.

G. Executive Order 13045: Protection of Children From Environmental 
Health and Safety Risks

    Executive Order 13045, ``Protection of Children from Environmental 
Health and Safety Risks'' (62 FR 19885, April 23, 1997) applies to any 
rule that (1) is determined to be ``economically significant'' as 
defined under Executive Order 12866, and (2) concerns an environmental 
health or safety risk that EPA has reason to believe may have a 
disproportionate effect on children. If the regulatory action meets 
both criteria, Section 5-501 of the Order directs the Agency to 
evaluate the environmental health or safety effects of the planned rule 
on children, and explain why the planned regulation is preferable to 
other potentially effective and reasonably feasible alternatives 
considered by the Agency.
    This final rule is not subject to the Executive Order, because it 
does not involve decisions on environmental health or safety risks that 
may disproportionately affect children. The EPA believes that the 
emissions reductions from the strategies in this rule will further 
improve air quality and will further improve children's health.

H. Executive Order 13211: Actions That Significantly Affect Energy 
Supply, Distribution, or Use

    Executive Order 13211 (66 FR 28355, May 22, 2001) provides that 
agencies shall prepare and submit to the Administrator of the Office of 
Regulatory Affairs, OMB, a Statement of Energy Effects for certain 
actions identified as ``significant energy actions.'' Section 4(b) of 
Executive Order 13211 defines ``significant energy actions'' as ``any 
action by an agency (normally published in the Federal Register) that 
promulgates or is expected to lead to the promulgation of a final rule 
or regulation, including notices of inquiry, advance notices of final 
rulemaking, and notices of final rulemaking (1) (i) a significant 
regulatory action under Executive Order 12866 or any successor order, 
and (ii) likely to have a significant adverse effect on the supply, 
distribution, or use of energy; or (2) designated by the Administrator 
of the Office of Information and Regulatory Affairs as a ``significant 
energy action.'' This final rule is a significant regulatory action 
under Executive Order 12866, and this rule may have a significant 
adverse effect on the supply, distribution, or use of energy.
    If States choose to obtain the emissions reductions required by 
this rule by regulating EGUs, EPA projects that approximately 5.3 GWs 
of coal-fired generation may be removed from operation by 2010. In 
practice, however, the units projected to be uneconomic to maintain may 
be `mothballed,' retired, or kept in service to ensure transmission 
reliability in certain parts of the grid. For the most part, these 
units are small and infrequently used generating units that are 
dispersed throughout the CAIR region. Less conservative assumptions 
regarding natural gas prices or electricity demand would create a 
greater incentive to keep these units operational. The EPA projects 
that the

[[Page 25316]]

average annual electricity price will increase by less than 2.7 percent 
in the CAIR region and that natural gas prices will increase by less 
than 1.6 percent. The EPA does not believe that this rule will have any 
other impacts that exceed the significance criteria.
    The EPA believes that a number of features of today's rulemaking 
serve to reduce its impact on energy supply. First, the optional 
trading program provides considerable flexibility to the power sector 
and enables industry to comply with the emission reduction requirements 
in the most cost-effective manner, thus minimizing overall costs and 
the ultimate impact on energy supply. The ability to use banked 
allowances from the existing title IV SO2 trading program 
and the NOX SIP Call Trading Program also provide additional 
flexibility. Second, the CAIR caps are set in two phases and provide 
adequate time for EGUs to install pollution controls. For more details 
concerning energy impacts, see the Regulatory Impact Analysis for the 
Final Clean Air Interstate Rule (March 2005).

I. National Technology Transfer Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act (NTTAA) of 1995 (Pub. L. 104-113; 15 U.S.C. 272 note) directs EPA 
to use voluntary consensus standards in its regulatory and procurement 
activities unless to do so would be inconsistent with applicable law or 
otherwise impractical. Voluntary consensus standards are technical 
standards (e.g., materials specifications, test methods, sampling 
procedures, business practices) developed or adopted by one or more 
voluntary consensus bodies. The NTTAA directs EPA to provide Congress, 
through annual reports to OMB, with explanations when an agency does 
not use available and applicable voluntary consensus standards.
    This rule would require all sources that participate in the trading 
program under part 96 to meet the applicable monitoring requirements of 
part 75. Part 75 already incorporates a number of voluntary consensus 
standards. Consistent with the Agency's Performance Based Measurement 
System (PBMS), part 75 sets forth performance criteria that allow the 
use of alternative methods to the ones set forth in part 75. The PBMS 
approach is intended to be more flexible and cost-effective for the 
regulated community; it is also intended to encourage innovation in 
analytical technology and improved data quality. At this time, EPA is 
not recommending any revisions to part 75; however, EPA periodically 
revises the test procedures set forth in part 75. When EPA revises the 
test procedures set forth in part 75 in the future, EPA will address 
the use of any new voluntary consensus standards that are equivalent. 
Currently, even if a test procedure is not set forth in part 75 EPA is 
not precluding the use of any method, whether it constitutes a 
voluntary consensus standard or not, as long as it meets the 
performance criteria specified; however, any alternative methods must 
be approved through the petition process under Sec. 75.66 before they 
are used under part 75.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    Executive Order 12898, ``Federal Actions to Address Environmental 
Justice in Minority Populations and Low-Income Populations,'' requires 
Federal agencies to consider the impact of programs, policies, and 
activities on minority populations and low-income populations. 
According to EPA guidance,\179\ agencies are to assess whether minority 
or low-income populations face risks or a rate of exposure to hazards 
that are significant and that ``appreciably exceed or is likely to 
appreciably exceed the risk or rate to the general population or to the 
appropriate comparison group.'' (EPA, 1998)
---------------------------------------------------------------------------

    \179\ U.S. Environmental Protection Agency, 1998. Guidance for 
Incorporating Environmental Justice Concerns in EPA's NEPA 
Compliance Analyses. Office of Federal Activities, Washington, DC, 
April, 1998.
---------------------------------------------------------------------------

    In accordance with Executive Order 12898, the Agency has considered 
whether this rule may have disproportionate negative impacts on 
minority or low income populations. The Agency expects this rule to 
lead to reductions in air pollution and exposures generally. For this 
reason, negative impacts to these sub-populations that appreciably 
exceed similar impacts to the general population are not expected.

K. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. The EPA will submit a report containing this rule and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A Major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is a ``major rule'' as defined by 5 U.S.C. 804(2).

L. Judicial Review

    Section 307(b)(1) of the CAA indicates which Federal Courts of 
Appeal have venue for petitions of review of final actions by EPA. This 
Section provides, in part, that petitions for review must be filed in 
the Court of Appeals for the District of Columbia Circuit if (i) the 
agency action consists of ``nationally applicable regulations 
promulgated, or final action taken, by the Administrator,'' or (ii) 
such action is locally or regionally applicable, if ``such action is 
based on a determination of nationwide scope or effect and if in taking 
such action the Administrator finds and publishes that such action is 
based on such a determination.''
    Any final action related to CAIR is ``nationally applicable'' 
within the meaning of section 307(b)(1). As an initial matter, through 
this rule, EPA interprets section 110 of the CAA, a provision which has 
nationwide applicability. In addition, CAIR applies to 28 States and 
the District of Columbia. CAIR is also based on a common core of 
factual findings and analyses concerning the transport of pollutants 
between the different States subject to it. Finally, EPA has 
established uniform approvability criteria that would be applied to all 
States subject to CAIR. For these reasons, the Administrator also is 
determining that any final action regarding CAIR is of nationwide scope 
and effect for purposes of section 307(b)(1). Thus, any petitions for 
review of final actions regarding CAIR must be filed in the Court of 
Appeals for the District of Columbia Circuit within 60 days from the 
date final action is published in the Federal Register.

? 2. Section 51.121 is amended by adding a new paragraph (r) to read as 
follows:

Sec.  51.121  Findings and requirements for submission of State 
implementation plan revisions relating to emissions of oxides of 
nitrogen.

* * * * *
    (r)(1) Notwithstanding any provisions of paragraph (p) of this 
section, subparts A through I of part 96 of this chapter, and any 
State's SIP to the contrary, the Administrator will not carry out any 
of the functions set forth for the Administrator in subparts A through 
I of part 96 of this chapter, or in any emissions trading program in a 
State's SIP approved under paragraph (p) of this section, with regard 
to any ozone season that occurs after September 30, 2008.
    (2) Except as provided in Sec.  51.123(bb), a State whose SIP is 
approved as meeting the requirements of this section and that includes 
an emissions trading program approved under paragraph (p) of this 
section must revise the SIP to adopt control measures that satisfy the 
same portion of the State's NOX emission reduction 
requirements under this section as the State projected such emissions 
trading program would satisfy.

? 3. Revise Sec.  51.122 of subpart G to read as follows:

Sec.  51.122  Emissions reporting requirements for SIP revisions

                Table 1.--Schedule for Submitting Reports
------------------------------------------------------------------------
            Data collection year               Type of  report required
------------------------------------------------------------------------
2002.......................................  Trienniel.
2003.......................................  Annual.
2004.......................................  Annual.
2005.......................................  Trienniel.
2006.......................................  Annual.
2007.......................................  Annual.
2008.......................................  Trienniel.
------------------------------------------------------------------------

    (3) States must submit data for a required year no later than 12 
months after the end of the calendar year for which the data are collected.
    (h) Data Reporting Procedures. When submitting a formal 
NOX budget emissions report and associated data, States 
shall notify the appropriate EPA Regional Office.
    (1) States are required to report emissions data in an electronic 
format to EPA. Several options are available for data reporting. States 
can obtain information on the current formats at the following Internet 
address: http://www.epa.gov/ttn/chief, by calling the EPA Info CHIEF 
help desk at (919) 541-1000 or by sending an e-mail to 
info.chief@epa.gov. Because electronic reporting technology continually 
changes, States are to contact the Emission Inventory Group (EIG) for 
the latest specific formats.
    (2) For annual reporting (not for triennial reports), a State may 
have sources submit the data directly to EPA to the extent the sources 
are subject to a trading program that qualifies for approval under 
Sec.  51.121(q), and the State has agreed to accept data in this 
format. The EPA will make both the raw data submitted in this format 
and summary data available to any State that chooses this option.
    (i) Definitions. As used in this section, the following words and 
terms shall have the meanings set forth below:
    (1) Annual emissions. Actual emissions for a plant, point, or 
process, either measured or calculated.
    (2) Ash content. Inert residual portion of a fuel.
    (3) Area designation. The designation of the area in which the 
reporting source is located with regard to the ozone NAAQS. This would 
include attainment or nonattainment designations. For nonattainment 
designations, the classification of the nonattainment area must be 
specified, i.e., transitional, marginal, moderate, serious, severe, or

spring, summer, fall, and winter. It can be represented either as a 
percentage of the annual activity (e.g., production in summer is 40 
percent of the year's production), or in terms of the units of the 
activity (e.g., out of 600 units produced, spring = 150 units, summer =

NOX per year than the point source threshold is a non-point 
source.
    (25) Pollutant code. A unique code for each reported pollutant that 
has been assigned in the EIIP Data Model. Character names are used for 
criteria pollutants, while Chemical Abstracts Service (CAS) numbers are 
used for all other pollutants. Some States may be using storage and 
retrieval of aerometric data (SAROAD) codes for pollutants, but these 
should be able to be mapped to the EIIP Data Model pollutant codes.
    (26) Process rate/throughput. A measurable factor or parameter that 
is directly or indirectly related to the emissions of an air pollution 
source. Depending on the type of source category, activity information 
may refer to the amount of fuel combusted, the amount of a raw material 
processed, the amount of a product that is manufactured, the amount of 
a material that is handled or processed, population, employment, number 
of units, or miles traveled. Activity information is typically the

activity that is used with emission factors. The emission factors are 
usually expressed in terms of grams per mile of travel. Since VMT does 
not directly correlate to emissions that occur while the vehicle is not 
moving, these non-moving emissions are incorporated into EPA's MOBILE 
model emission factors.
    (39) Week/year in operation. Weeks per year that the emitting 
process operates.

    (3) The State shall deliver 5 copies of the SIP revision under 
paragraph (a) of this section to the appropriate Regional Office, with 
a letter giving notice of such action.
    (e) The State's SIP revision shall contain control measures and 
demonstrate that they will result in compliance with the State's Annual 
EGU NOX Budget, if applicable, and achieve the State's 
Annual Non-EGU NOX Reduction Requirement, if applicable, for 
the appropriate periods. The amounts of the State's Annual EGU 
NOX Budget and Annual Non-EGU NOX Reduction 
Requirement shall be determined as follows:
    (1)(i) The Annual EGU NOX Budget for the State is 
defined as the total amount of NOX emissions from all EGUs 
in that State for a year, if the State meets the requirements of 
paragraph (a)(1) of this section by imposing control measures, at least 
in part, on EGUs. If the State imposes control measures

[[Page 25320]]

under this section on only EGUs, the Annual EGU NOX Budget 
for the State shall not exceed the amount, during the indicated 
periods, specified in paragraph (e)(2) of this section.
    (ii) The Annual Non-EGU NOX Reduction Requirement, if 
applicable, is defined as the total amount of NOX emission 
reductions that the State demonstrates, in accordance with paragraph 
(g) of this section, it will achieve from non-EGUs during the 
appropriate period. If the State meets the requirements of paragraph 
(a)(1) of this section by imposing control measures on only non-EGUs, 
then the State's Annual Non-EGU NOX Reduction Requirement 
shall equal or exceed, during the appropriate periods, the amount 
determined in accordance with paragraph (e)(3) of this section.
    (iii) If a State meets the requirements of paragraph (a)(1) of this 
section by imposing control measures on both EGUs and non-EGUs, then:
    (A) The Annual Non-EGU NOX Reduction Requirement shall 
equal or exceed the difference between the amount specified in 
paragraph (e)(2) of this section for the appropriate period and the 
amount of the State's Annual EGU NOX Budget specified in the 
SIP revision for the appropriate period; and
    (B) The Annual EGU NOX Budget shall not exceed, during 
the indicated periods, the amount specified in paragraph (e)(2) of this 
section plus the amount of the Annual Non-EGU NOX Reduction 
Requirement under paragraph (e)(1)(iii)(A) of this section for the 
appropriate period.
    (2) For a State that complies with the requirements of paragraph 
(a)(1) of this section by imposing control measures on only EGUs, the 
amount of the Annual EGU NOX Budget, in tons of 
NOX per year, shall be as follows, for the indicated State 
for the indicated period:

    (iii) The SIP revision may provide for the distribution of credits 
from the compliance supplement pool to sources

[[Page 25321]]

that are required to implement control measures using one or both of 
the following two mechanisms:
    (A) The State may issue credit from compliance supplement pool to 
sources that are required by the SIP revision to implement 
NOX emission control measures and that implement 
NOX emission reductions in 2007 and 2008 that are not 
necessary to comply with any State or federal emissions limitation 
applicable at any time during such years. Such a source may be issued 
one credit from the compliance supplement pool for each ton of such 
emission reductions in 2007 and 2008.
    (1) The State shall complete the issuance process by January 1, 2010.
    (2) The emissions reductions for which credits are issued must have 
been demonstrated by the owners and operators of the source to have 
occurred during 2007 and 2008 and not to be necessary to comply with 
any applicable State or federal emissions limitation.
    (3) The emissions reductions for which credits are issued must have 
been quantified by the owners and operators of the source:
    (i) For EGUs and for fossil-fuel-fired non-EGUs that are boilers or 
combustion turbines with a maximum design heat input greater than 250 
mmBut/hr, using emissions data determined in accordance with subpart H 
of part 75 of this chapter; and
    (ii) For non-EGUs not described in paragraph (e)(4)(iii)(A)(3)(i) 
of this section, using emissions data determined in accordance with 
subpart H of part 75 of this chapter or, if the State demonstrates that 
compliance with subpart H of part 75 of this chapter is not 
practicable, determined, to the extent practicable, with the same 
degree of assurance with which emissions data are determined for 
sources subject to subpart H of part 75.
    (4) If the SIP revision contains approved provisions for an 
emissions trading program, the owners and operators of sources that 
receive credit according to the requirements of this paragraph may 
transfer the credit to other sources or persons according to the 
provisions in the emissions trading program.
    (B) The State may issue credit from the compliance supplement pool 
to sources that are required by the SIP revision to implement 
NOX emission control measures and whose owners and operators 
demonstrate a need for an extension, beyond 2009, of the deadline for 
the source for implementing such emission controls.
    (1) The State shall complete the issuance process by January 1, 2010.
    (2) The State shall issue credit to a source only if the owners and 
operators of the source demonstrate that:
    (i) For a source used to generate electricity, implementation of 
the SIP revision's applicable control measures by 2009 would create 
undue risk for the reliability of the electricity supply. This 
demonstration must include a showing that it would not be feasible for 
the owners and operators of the source to obtain a sufficient amount of 
electricity, to prevent such undue risk, from other electricity 
generation facilities during the installation of control technology at 
the source necessary to comply with the SIP revision.
    (ii) For a source not used to generate electricity, compliance with 
the SIP revision's applicable control measures by 2009 would create 
undue risk for the source or its associated industry to a degree that 
is comparable to the risk described in paragraph (e)(4)(iii)(B)(2)(i) 
of this section.
    (iii) This demonstration must include a showing that it would not 
be possible for the source to comply with applicable control measures 
by obtaining sufficient credits under paragraph (e)(4)(iii)(A) of this 
section, or by acquiring sufficient credits from other sources or 
persons, to prevent undue risk.
    (f) Each SIP revision must set forth control measures to meet the 
amounts specified in paragraph (e) of this section, as applicable, 
including the following:
    (1) A description of enforcement methods including, but not limited to:
    (i) Procedures for monitoring compliance with each of the selected 
control measures;
    (ii) Procedures for handling violations; and
    (iii) A designation of agency responsibility for enforcement of 
implementation.
    (2)(i) If a State elects to impose control measures on EGUs, then 
those measures must impose an annual NOX mass emissions cap 
on all such sources in the State.
    (ii) If a State elects to impose control measures on fossil fuel-
fired non-EGUs that are boilers or combustion turbines with a maximum 
design heat input greater than 250 mmBtu/hr, then those measures must 
impose an annual NOX mass emissions cap on all such sources 
in the State.
    (iii) If a State elects to impose control measures on non-EGUs 
other than those described in paragraph (f)(2)(ii) of this section, 
then those measures must impose an annual NOX mass emissions 
cap on all such sources in the State or the State must demonstrate why 
such emissions cap is not practicable and adopt alternative 
requirements that ensure that the State will comply with its 
requirements under paragraph (e) of this section, as applicable, in 
2009 and subsequent years.
    (g)(1) Each SIP revision that contains control measures covering 
non-EGUs as part or all of a State's obligation in meeting its 
requirement under paragraph (a)(1) of this section must demonstrate 
that such control measures are adequate to provide for the timely 
compliance with the State's Annual Non-EGU NOX Reduction 
Requirement under paragraph (e) of this section and are not adopted or 
implemented by the State, as of May 12, 2005, and are not adopted or 
implemented by the Federal government, as of the date of submission of 
the SIP revision by the State to EPA.
    (2) The demonstration under paragraph (g)(1) of this section must 
include the following, with respect to each source category of non-EGUs 
for which the SIP revision requires control measures:
    (i) A detailed historical baseline inventory of NOX mass 
emissions from the source category in a representative year consisting, 
at the State's election, of 2002, 2003, 2004, or 2005, or an average of 
2 or more of those years, absent the control measures specified in the 
SIP revision.
    (A) This inventory must represent estimates of actual emissions 
based on monitoring data in accordance with subpart H of part 75 of 
this chapter, if the source category is subject to monitoring 
requirements in accordance with subpart H of part 75 of this chapter.
    (B) In the absence of monitoring data in accordance with subpart H 
of part 75 of this chapter, actual emissions must be quantified, to the 
maximum extent practicable, with the same degree of assurance with 
which emissions are quantified for sources subject to subpart H of part 
75 of this chapter and using source-specific or source-category-
specific assumptions that ensure a source's or source category's actual 
emissions are not overestimated. If a State uses factors to estimate 
emissions, production or utilization, or effectiveness of controls or 
rules for a source category, such factors must be chosen to ensure that 
emissions are not overestimated.
    (C) For measures to reduce emissions from motor vehicles, emission 
estimates must be based on an emissions model that has been approved by 
EPA for use in SIP development and must be consistent with the planning 
assumptions regarding vehicle miles

[[Page 25322]]

traveled and other factors current at the time of the SIP development.
    (D) For measures to reduce emissions from nonroad engines or 
vehicles, emission estimates methodologies must be approved by EPA.
    (ii) A detailed baseline inventory of NOX mass emissions 
from the source category in the years 2009 and 2015, absent the control 
measures specified in the SIP revision and reflecting changes in these 
emissions from the historical baseline year to the years 2009 and 2015, 
based on projected changes in the production input or output, 
population, vehicle miles traveled, economic activity, or other factors 
as applicable to this source category.
    (A) These inventories must account for implementation of any 
control measures that are otherwise required by final rules already 
promulgated, as of May 12, 2005, or adopted or implemented by any 
federal agency, as of the date of submission of the SIP revision by the 
State to EPA, and must exclude any control measures specified in the 
SIP revision to meet the NOX emissions reduction 
requirements of this section.
    (B) Economic and population forecasts must be as specific as 
possible to the applicable industry, State, and county of the source or 
source category and must be consistent with both national projections 
and relevant official planning assumptions, including estimates of 
population and vehicle miles traveled developed through consultation 
between State and local transportation and air quality agencies. 
However, if these official planning assumptions are inconsistent with 
official U.S. Census projections of population or with energy 
consumption projections contained in the U.S. Department of Energy's 
most recent Annual Energy Outlook, then the SIP revision must make 
adjustments to correct the inconsistency or must demonstrate how the 
official planning assumptions are more accurate.

2015 from the source category assuming the same projected changes as 
under paragraph (g)(2)(ii) of this section and resulting from 
implementation of each of the control measures specified in the SIP 
revision.
    (A) These inventories must address the possibility that the State's 
new control measures may cause production or utilization, and 
emissions, to shift to unregulated or less stringently regulated 
sources in the source category in the same or another State, and these 
inventories must include any such amounts of emissions that may shift 
to such other sources.
    (B) The State must provide EPA with a summary of the computations, 
assumptions, and judgments used to determine the degree of reduction in 
projected 2009 and 2015 NOX emissions that will be achieved 
from the implementation of the new control measures compared to the 
relevant baseline emissions inventory.
    (iv) The result of subtracting the amounts in paragraph (g)(2)(iii) 
of this section for 2009 and 2015, respectively, from the lower of the 
amounts in paragraph (g)(2)(i) or (g)(2)(ii) of this section for 2009 
and 2015, respectively, may be credited towards the State's Annual Non-
EGU NOX Reduction Requirement in paragraph (e)(3) of this 
section for the appropriate period.

the SIP revision must require such sources to comply with the 
monitoring, recordkeeping, and reporting provisions of subpart H of 
part 75 of this chapter.
    (ii) If the SIP revision contains measures to control fossil fuel-
fired non-EGUs that are boilers or combustion turbines with a maximum 
design heat input greater than 250 mmBtu/hr, then the SIP revision must 
require such sources to comply with the monitoring, recordkeeping, and 
reporting provisions of subpart H of part 75 of this chapter.
    (iii) If the SIP revision contains measures to control any other 
non-EGUs that are not described in paragraph (i)(4)(ii) of this 
section, then the SIP revision must require such sources to comply with

State adopts regulations substantively identical to subparts AA through 
II of part 96 of this chapter (CAIR NOX Annual Trading 
Program), incorporates such subparts by reference into its regulations, 
or adopts regulations that differ substantively from such subparts only 
as set forth in paragraph (o)(2) of this section, then such emissions 
trading program in the State's SIP revision is automatically approved 
as meeting the requirements of paragraph (e) of this section, provided 
that the State has the legal authority to take such action and to 
implement its responsibilities under such regulations.
    (2) If a State adopts an emissions trading program that differs 
substantively from subparts AA through II of part 96 of this chapter 
only as follows, then the emissions trading program is approved as set 
forth in paragraph (o)(1) of this section.
    (i) The State may decline to adopt the CAIR NOX opt-in 
provisions of:
    (A) Subpart II of this part and the provisions applicable only to 
CAIR NOX opt-in units in subparts AA through HH of this part;

CAIR NOX allowances for a year in excess of the amount in 
the State's Annual EGU NOX Budget for such year;
    (B) The State's methodology must require that, for EGUs commencing 
operation before January 1, 2001, the State will determine, and notify 
the Administrator of, each unit's allocation of CAIR NOX 
allowances by October 31, 2006 for 2009, 2010, and 2011 and by October 
31, 2008 and October 31 of each year thereafter for the year after the 
year of the notification deadline; and
    (C) The State's methodology must require that, for EGUs commencing 
operation on or after January 1, 2001, the State will determine, and 
notify the Administrator of, each unit's allocation of CAIR

paragraph (o)(1) or (2) of this section and will be reviewed by the 
Administrator for approvability in accordance with the other provisions 
of this section, provided that the NOX allowances issued 
under such emissions trading program shall not, and the SIP revision 
shall state that such NOX allowances shall not, qualify as 
CAIR NOX allowances or CAIR NOX Ozone Season 
allowances under any emissions trading program approved under 
paragraphs (o)(1) or (2) or (aa)(1) or (2) of this section.
    (p) [Reserved]
    (q) The State's SIP revision shall contain control measures and 
demonstrate that they will result in compliance with the State's Ozone 
Season EGU NOX Budget, if applicable, and achieve the 
State's Ozone Season Non-EGU NOX Reduction Requirement, if 
applicable, for the appropriate periods. The amounts of the State's 
Ozone Season EGU NOX Budget and Ozone Season Non-EGU 
NOX Reduction Requirement shall be determined as follows:
    (1)(i) The Ozone Season EGU NOX Budget for the State is 
defined as the total amount of NOX emissions from all EGUs 
in that State for an ozone season, if the State meets the requirements 
of paragraph (a)(2) of this section by imposing control measures, at 
least in part, on EGUs. If the State imposes control measures under 
this section on only EGUs, the Ozone Season EGU NOX Budget 
for the State shall not exceed the amount, during the indicated 
periods, specified in paragraph (q)(2) of this section.
    (ii) The Ozone Season Non-EGU NOX Reduction Requirement, 
if applicable, is defined as the total amount of NOX 
emission reductions that the State demonstrates, in accordance with 
paragraph (s) of this section, it will achieve from non-EGUs during the 
appropriate period. If the State meets the requirements of paragraph 
(a)(2) of this section by imposing control measures on only non-EGUs, 
then the State's Ozone Season Non-EGU NOX Reduction 
Requirement shall equal or exceed, during the appropriate periods, the 
amount determined in accordance with paragraph (q)(3) of this section.
    (iii) If a State meets the requirements of paragraph (a)(2) of this 
section by imposing control measures on both EGUs and non-EGUs, then:
    (A) The Ozone Season Non-EGU NOX Reduction Requirement 
shall equal or exceed the difference between the amount specified in 
paragraph (q)(2) of this section for the appropriate period and the 
amount of the State's Ozone Season EGU NOX Budget specified 
in the SIP revision for the appropriate period; and
    (B) The Ozone Season EGU NOX Budget shall not exceed, 
during the indicated periods, the amount specified in paragraph (e)(2) 
of this section plus the amount of the Ozone Season Non-EGU 
NOX Reduction Requirement under paragraph (q)(1)(iii)(A) of 
this section for the appropriate period.
    (2) For a State that complies with the requirements of paragraph 
(a)(2) of this section by imposing control measures on only EGUs, the 
amount of the Ozone Season EGU NOX Budget, in tons of 
NOX per ozone season, shall be as follows, for the indicated 
State for the indicated period:

    (3) For a State that complies with the requirements of paragraph 
(a)(2) of this section by imposing control measures on only non-EGUs, 
the amount of the Ozone Season Non-EGU NOX Reduction 
Requirement, in tons of NOX per ozone season, shall be 
determined, for the State for 2009 and thereafter, by subtracting the 
amount of the State's Ozone Season EGU NOX Budget for the 
appropriate year, specified in paragraph (e)(2) of this section, from 
the amount of the State's NOX baseline EGU emissions 
inventory projected for the ozone season in the appropriate year, 
specified in Table 7 of ``Regional and State SO2 and 
NOX Budgets'', March 2005 (available at: http://www.epa.gov/
cleanairinterstaterule).
    (4) Notwithstanding the State's obligation to comply with paragraph 
(q)(2) or (3) of this section, the State's SIP revision may allow 
sources required by the revision to implement NOX emission 
control measures to demonstrate compliance using NOX SIP 
Call allowances allocated under the NOX Budget Trading 
Program for any ozone season during 2003 through 2008 that have not 
been deducted by the Administrator under the NOX Budget 
Trading Program, if the SIP revision ensures that such allowances will 
not be available for such deduction under the NOX Budget 
Trading Program.
    (r) Each SIP revision must set forth control measures to meet the 
amounts specified in paragraph (q) of this section, as applicable, 
including the following:
    (1) A description of enforcement methods including, but not limited to:
    (i) Procedures for monitoring compliance with each of the selected 
control measures;
    (ii) Procedures for handling violations; and
    (iii) A designation of agency responsibility for enforcement of 
implementation.
    (2)(i) If a State elects to impose control measures on EGUs, then 
those measures must impose an ozone season NOX mass 
emissions cap on all such sources in the State.
    (ii) If a State elects to impose control measures on fossil fuel-
fired non-EGUs that are boilers or combustion turbines with a maximum 
design heat input greater than 250 mmBtu/hr, then those measures must 
impose an ozone season NOX mass emissions cap on all such 
sources in the State.
    (iii) If a State elects to impose control measures on non-EGUs 
other than those described in paragraph (r)(2)(ii) of this section, 
then those measures must impose an ozone season NOX mass 
emissions cap on all such sources in the State or the State must 
demonstrate why such emissions cap is not practicable and adopt 
alternative requirements that ensure that the State will comply with 
its requirements under paragraph (q) of this section, as applicable, in 
2009 and subsequent years.
    (s)(1) Each SIP revision that contains control measures covering 
non-EGUs as part or all of a State's obligation in meeting its 
requirement under paragraph (a)(2) of this section must demonstrate 
that such control measures are adequate to provide for the timely 
compliance with the State's Ozone Season Non-EGU NOX 
Reduction Requirement under paragraph (q) of this section and are not 
adopted or implemented by the State, as of May 12, 2005, and are not 
adopted or implemented by the federal government, as of the date of 
submission of the SIP revision by the State to EPA.
    (2) The demonstration under paragraph (s)(1) of this section must 
include the following, with respect to each source category of non-EGUs 
for which the SIP revision requires control measures:
    (i) A detailed historical baseline inventory of NOX mass 
emissions from the source category in a representative ozone season 
consisting, at the State's election, of the ozone season in 2002, 2003, 
2004, or 2005, or an average of 2 or more of those ozone seasons, 
absent the control measures specified in the SIP revision.
    (A) This inventory must represent estimates of actual emissions 
based on monitoring data in accordance with subpart H of part 75 of 
this chapter, if the source category is subject to

[[Page 25325]]

monitoring requirements in accordance with subpart H of part 75 of this 
chapter.
    (B) In the absence of monitoring data in accordance with subpart H 
of part 75 of this chapter, actual emissions must be quantified, to the 
maximum extent practicable, with the same degree of assurance with 
which emissions are quantified for sources subject to subpart H of part 
75 of this chapter and using source-specific or source-category-
specific assumptions that ensure a source's or source category's actual 
emissions are not overestimated. If a State uses factors to estimate 
emissions, production or utilization, or effectiveness of controls or 
rules for a source category, such factors must be chosen to ensure that 
emissions are not overestimated.
    (C) For measures to reduce emissions from motor vehicles, emission 
estimates must be based on an emissions model that has been approved by 
EPA for use in SIP development and must be consistent with the planning 
assumptions regarding vehicle miles traveled and other factors current 
at the time of the SIP development.
    (D) For measures to reduce emissions from nonroad engines or 
vehicles, emission estimates methodologies must be approved by EPA.
    (ii) A detailed baseline inventory of NOX mass emissions 
from the source category in ozone seasons 2009 and 2015, absent the 
control measures specified in the SIP revision and reflecting changes 
in these emissions from the historical baseline ozone season to the 
ozone seasons 2009 and 2015, based on projected changes in the 
production input or output, population, vehicle miles traveled, 
economic activity, or other factors as applicable to this source category.
    (A) These inventories must account for implementation of any 
control measures that are adopted or implemented by the State, as of 
May 12, 2005, or adopted or implemented by the federal government, as 
of the date of submission of the SIP revision by the State to EPA, and 
must exclude any control measures specified in the SIP revision to meet 
the NOX emissions reduction requirements of this section.
    (B) Economic and population forecasts must be as specific as 
possible to the applicable industry, State, and county of the source or 
source category and must be consistent with both national projections 
and relevant official planning assumptions including estimates of 
population and vehicle miles traveled developed through consultation 
between State and local transportation and air quality agencies. 
However, if these official planning assumptions are inconsistent with 
official U.S. Census projections of population or with energy 
consumption projections contained in the U.S. Department of Energy's 
most recent Annual Energy Outlook, then the SIP revision must make 
adjustments to correct the inconsistency or must demonstrate how the 
official planning assumptions are more accurate.
    (C) These inventories must account for any changes in production 
method, materials, fuels, or efficiency that are expected to occur 
between the historical baseline ozone season and ozone season 2009 or 
ozone season 2015, as appropriate.
    (iii) A projection of NOX mass emissions in ozone season 
2009 and ozone season 2015 from the source category assuming the same 
projected changes as under paragraph (s)(2)(ii) of this section and 
resulting from implementation of each of the control measures specified 
in the SIP revision.
    (A) These inventories must address the possibility that the State's 
new control measures may cause production or utilization, and 
emissions, to shift to unregulated or less stringently regulated 
sources in the source category in the same or another State, and these 
inventories must include any such amounts of emissions that may shift 
to such other sources.
    (B) The State must provide EPA with a summary of the computations, 
assumptions, and judgments used to determine the degree of reduction in 
projected ozone season 2009 and ozone season 2015 NOX 
emissions that will be achieved from the implementation of the new 
control measures compared to the relevant baseline emissions inventory.
    (iv) The result of subtracting the amounts in paragraph (s)(2)(iii) 
of this section for ozone season 2009 and ozone season 2015, 
respectively, from the lower of the amounts in paragraph (s)(2)(i) or 
(s)(2)(ii) of this section for ozone season 2009 and ozone season 2015, 
respectively, may be credited towards the State's Ozone Season Non-EGU 
NOX Reduction Requirement in paragraph (q)(3) of this 
section for the appropriate period.
    (v) Each SIP revision must identify the sources of the data used in 
each estimate and each projection of emissions.
    (t) Each SIP revision must comply with Sec.  51.116 (regarding data 
availability).
    (u) Each SIP revision must provide for monitoring the status of 
compliance with any control measures adopted to meet the State's 
requirements under paragraph (q) of this section as follows:
    (1) The SIP revision must provide for legally enforceable 
procedures for requiring owners or operators of stationary sources to 
maintain records of, and periodically report to the State:
    (i) Information on the amount of NOX emissions from the 
stationary sources; and
    (ii) Other information as may be necessary to enable the State to 
determine whether the sources are in compliance with applicable 
portions of the control measures;
    (2) The SIP revision must comply with Sec.  51.212 (regarding 
testing, inspection, enforcement, and complaints);
    (3) If the SIP revision contains any transportation control 
measures, then the SIP revision must comply with Sec.  51.213 
(regarding transportation control measures);
    (4)(i) If the SIP revision contains measures to control EGUs, then 
the SIP revision must require such sources to comply with the 
monitoring, recordkeeping, and reporting provisions of subpart H of 
part 75 of this chapter.
    (ii) If the SIP revision contains measures to control fossil fuel-
fired non-EGUs that are boilers or combustion turbines with a maximum 
design heat input greater than 250 mmBtu/hr, then the SIP revision must 
require such sources to comply with the monitoring, recordkeeping, and 
reporting provisions of subpart H of part 75 of this chapter.
    (iii) If the SIP revision contains measures to control any other 
non-EGUs that are not described in paragraph (u)(4)(ii) of this 
section, then the SIP revision must require such sources to comply with 
the monitoring, recordkeeping, and reporting provisions of subpart H of 
part 75 of this chapter, or the State must demonstrate why such 
requirements are not practicable and adopt alternative requirements 
that ensure that the required emissions reductions will be quantified, 
to the maximum extent practicable, with the same degree of assurance 
with which emissions are quantified for sources subject to subpart H of 
part 75 of this chapter.
    (v) Each SIP revision must show that the State has legal authority 
to carry out the SIP revision, including authority to:
    (1) Adopt emissions standards and limitations and any other 
measures necessary for attainment and maintenance of the State's 
relevant Ozone Season EGU NOX Budget or the Ozone Season 
Non-EGU NOX Reduction Requirement, as applicable, under 
paragraph (q) of this section;

[[Page 25326]]

    (2) Enforce applicable laws, regulations, and standards and seek 
injunctive relief;
    (3) Obtain information necessary to determine whether air pollution

standards, including authority to require recordkeeping and to make 
inspections and conduct tests of air pollution sources; and
    (4)(i) Require owners or operators of stationary sources to 
install, maintain, and use emissions monitoring devices and to make 
periodic reports to the State on the nature and amounts of emissions 
from such stationary sources; and
    (ii) Make the data described in paragraph (v)(4)(i) of this section 
available to the public within a reasonable time after being reported 
and as correlated with any applicable emissions standards or limitations.
    (w)(1) The provisions of law or regulation that the State 
determines provide the authorities required under this section must be 
specifically identified, and copies of such laws or regulations must be 
submitted with the SIP revision.
    (2) Legal authority adequate to fulfill the requirements of 
paragraphs (v)(3) and (4) of this section may be delegated to the State 
under section 114 of the CAA.
    (x)(1) A SIP revision may assign legal authority to local agencies 
in accordance with Sec.  51.232.
    (2) Each SIP revision must comply with Sec.  51.240 (regarding 
general plan requirements).
    (y) Each SIP revision must comply with Sec.  51.280 (regarding 
resources).
    (z) Each SIP revision must provide for State compliance with the 
reporting requirements in Sec.  51.125.

    (3) For a State that complies with the requirements of paragraph 
(a) of this section by imposing control measures on only non-EGUs, the 
amount of the Annual Non-EGU SO2 Reduction Requirement, in 
tons of SO2 per year, shall be determined, for the State for 
2010 and thereafter, by subtracting the amount of the State's Annual 
EGU SO2 Budget for the appropriate year, specified in 
paragraph (e)(2) of this section, from an amount equal to 2 times the 
State's Annual EGU SO2 Budget for 2010 through 2014, 
specified in paragraph (e)(2) of this section.
    (f) Each SIP revision must set forth control measures to meet the 
amounts specified in paragraph (e) of this section, as applicable, 
including the following:
    (1) A description of enforcement methods including, but not limited 
to:
    (i) Procedures for monitoring compliance with each of the selected 
control measures;
    (ii) Procedures for handling violations; and
    (iii) A designation of agency responsibility for enforcement of 
implementation.
    (2)(i) If a State elects to impose control measures on EGUs, then 
those measures must impose an annual SO2 mass emissions cap 
on all such sources in the State.
    (ii) If a State elects to impose control measures on fossil fuel-
fired non-EGUs that are boilers or combustion turbines with a maximum 
design heat input greater than 250 mmBtu/hr, then those measures must 
impose an annual SO2 mass emissions cap on all such sources 
in the State.
    (iii) If a State elects to impose control measures on non-EGUs 
other than those described in paragraph (f)(2)(ii) of this section, 
then those measures must impose an annual SO2 mass emissions 
cap on all such sources in the State, or the State must demonstrate why 
such emissions cap is not practicable, and adopt alternative 
requirements that ensure that the State will comply with its 
requirements under paragraph (e) of this section, as applicable, in 
2010 and subsequent years.
    (g)(1) Each SIP revision that contains control measures covering 
non-EGUs as part or all of a State's obligation in meeting its 
requirement under paragraph (a) of this section must demonstrate that 
such control measures are adequate to provide for the timely compliance 
with the State's Annual Non-EGU SO2 Reduction Requirement 
under paragraph (e) of this section and are not adopted or implemented 
by the State, as of May 12, 2005, and are not adopted or implemented by 
the federal government, as of the date of submission of the SIP 
revision by the State to EPA.
    (2) The demonstration under paragraph (g)(1) of this section must 
include the following, with respect to each source category of non-EGUs 
for which the SIP revision requires control measures:
    (i) A detailed historical baseline inventory of SO2 mass 
emissions from the source category in a representative year consisting, 
at the State's election, of 2002, 2003, 2004, or 2005, or an average of 
2 or more of those years, absent the control measures specified in the 
SIP revision.
    (A) This inventory must represent estimates of actual emissions 
based on monitoring data in accordance with part 75 of this chapter, if 
the source category is subject to part 75 monitoring requirements in 
accordance with part 75 of this chapter.
    (B) In the absence of monitoring data in accordance with part 75 of 
this chapter, actual emissions must be quantified, to the maximum 
extent practicable, with the same degree of assurance with which 
emissions are quantified for sources subject to part 75 of this chapter 
and using source-specific or source-category-specific assumptions that 
ensure a source's or source category's actual emissions are not 
overestimated. If a State uses factors to estimate emissions, 
production or utilization, or effectiveness of controls or rules for a 
source category, such factors must be chosen to ensure that emissions 
are not overestimated.
    (C) For measures to reduce emissions from motor vehicles, emission 
estimates must be based on an emissions model that has been approved by 
EPA for use in SIP development and must be consistent with the planning 
assumptions regarding vehicle miles traveled and other factors current 
at the time of the SIP development.
    (D) For measures to reduce emissions from nonroad engines or 
vehicles, emission estimates methodologies must be approved by EPA.
    (ii) A detailed baseline inventory of SO2 mass emissions 
from the source category in the years 2010 and 2015, absent the control 
measures specified in the SIP revision and reflecting changes in these 
emissions from the historical baseline year to the years 2010 and 2015, 
based on projected changes in the production input or output, 
population, vehicle miles traveled, economic activity, or other factors 
as applicable to this source category.
    (A) These inventories must account for implementation of any 
control measures that are adopted or implemented by the State, as of 
May 12, 2005, or adopted or implemented by the federal government, as 
of the date of submission of the SIP revision by the State to EPA, and 
must exclude any control measures specified in the SIP revision to meet 
the SO2 emissions reduction requirements of this section.
    (B) Economic and population forecasts must be as specific as 
possible to the applicable industry, State, and county of the source or 
source category and must be consistent with both national projections 
and relevant official planning assumptions, including estimates of 
population and vehicle miles traveled developed through consultation 
between State and local transportation and air quality agencies. 
However, if these official planning assumptions are inconsistent with 
official U.S. Census projections of population or with energy 
consumption projections contained in the U.S. Department of Energy's 
most recent Annual Energy Outlook, then the SIP revision must make 
adjustments to correct the inconsistency or must demonstrate how the 
official planning assumptions are more accurate.
    (C) These inventories must account for any changes in production 
method, materials, fuels, or efficiency that are expected to occur 
between the historical baseline year and 2010 or 2015, as appropriate.
    (iii) A projection of SO2 mass emissions in 2010 and 
2015 from the source category assuming the same projected changes as 
under paragraph (g)(2)(ii) of this section and resulting from 
implementation of each of the control measures specified in the SIP 
revision.
    (A) These inventories must address the possibility that the State's 
new control measures may cause production or utilization, and 
emissions, to shift to unregulated or less stringently regulated 
sources in the source category in the same or another State, and these 
inventories must include any such amounts of emissions that may shift 
to such other sources.
    (B) The State must provide EPA with a summary of the computations, 
assumptions, and judgments used to determine the degree of reduction in 
projected 2010 and 2015 SO2 emissions that will be achieved 
from the implementation of the new control measures compared to the 
relevant baseline emissions inventory.
    (iv) The result of subtracting the amounts in paragraph (g)(2)(iii) 
of this section for 2010 and 2015, respectively, from the lower of the 
amounts in paragraph (g)(2)(i) or (g)(2)(ii) of this section for 2010 
and 2015, respectively,

[[Page 25331]]

may be credited towards the State's Annual Non-EGU SO2 
Reduction Requirement in paragraph (e)(3) of this section for the 
appropriate period.
    (v) Each SIP revision must identify the sources of the data used in 
each estimate and each projection of emissions.
    (h) Each SIP revision must comply with Sec.  51.116 (regarding data 
availability).

stationary sources; and
    (ii) Other information as may be necessary to enable the State to 
determine whether the sources are in compliance with applicable 
portions of the control measures;
    (2) The SIP revision must comply with Sec.  51.212 (regarding 
testing, inspection, enforcement, and complaints);
    (3) If the SIP revision contains any transportation control 
measures, then the SIP revision must comply with Sec.  51.213 
(regarding transportation control measures);
    (4)(i) If the SIP revision contains measures to control EGUs, then 
the SIP revision must require such sources to comply with the 
monitoring, recordkeeping, and reporting provisions of part 75 of this 
chapter.
    (ii) If the SIP revision contains measures to control fossil fuel-
fired non-EGUs that are boilers or combustion turbines with a maximum 
design heat input greater than 250 mmBtu/hr, then the SIP revision must 
require such sources to comply with the monitoring, recordkeeping, and 
reporting provisions of part 75 of this chapter.
    (iii) If the SIP revision contains measures to control any other 
non-EGUs that are not described in paragraph (i)(4)(ii) of this 
section, then the SIP revision must require such sources to comply with 
the monitoring, recordkeeping, and reporting provisions of part 75 of 
this chapter, or the State must demonstrate why such requirements are 
not practicable and adopt alternative requirements that ensure that the 
required emissions reductions will be quantified, to the maximum extent 
practicable, with the same degree of assurance with which emissions are 
quantified for sources subject to part 75 of this chapter.
    (j) Each SIP revision must show that the State has legal authority 
to carry out the SIP revision, including authority to:
    (1) Adopt emissions standards and limitations and any other 
measures necessary for attainment and maintenance of the State's 
relevant Annual EGU SO2 Budget or the Annual Non-EGU 
SO2 Reduction Requirement, as applicable, under paragraph 
(e) of this section;
    (2) Enforce applicable laws, regulations, and standards and seek 
injunctive relief;
    (3) Obtain information necessary to determine whether air pollution 
sources are in compliance with applicable laws, regulations, and 
standards, including authority to require recordkeeping and to make 
inspections and conduct tests of air pollution sources; and

install, maintain, and use emissions monitoring devices and to make 
periodic reports to the State on the nature and amounts of emissions 
from such stationary sources; and
    (ii) Make the data described in paragraph (j)(4)(i) of this section 
available to the public within a reasonable time after being reported 
and as correlated with any applicable emissions standards or 
limitations.
    (k)(1) The provisions of law or regulation that the State 
determines provide the authorities required under this section must be 
specifically identified, and copies of such laws or regulations must be 
submitted with the SIP revision.
    (2) Legal authority adequate to fulfill the requirements of 
paragraphs (j)(3) and (4) of this section may be delegated to the State 
under section 114 of the CAA.
    (l)(1) A SIP revision may assign legal authority to local agencies 
in accordance with Sec.  51.232.
    (2) Each SIP revision must comply with Sec.  51.240 (regarding 
general plan requirements).
    (m) Each SIP revision must comply with Sec.  51.280 (regarding

State adopts regulations substantively identical to subparts AAA 
through III of part 96 of this chapter (CAIR SO2 Trading 
Program), incorporates such subparts by reference into its regulations, 
or adopts regulations that differ substantively from such subparts only 
as set forth in paragraph (o)(2) of this section, then such emissions 
trading program in the State's SIP revision is automatically approved 
as meeting the requirements of paragraph (e) of this section, provided 
that the State has the legal authority to take such action and to 
implement its responsibilities under such regulations.
    (2) If a State adopts an emissions trading program that differs 
substantively from subparts AAA through III of part 96 of this chapter 
only as follows, then the emissions trading program is approved as set 
forth in paragraph (o)(1) of this section.
    (i) The State may decline to adopt the CAIR SO2 opt-in 
provisions of subpart III of this part and the provisions applicable 
only to CAIR SO2 opt-in units in subparts AAA through HHH of 
this part.
    (ii) The State may decline to adopt the CAIR SO2 opt-in 
provisions of Sec.  96.288(b) of this chapter and the provisions of 
subpart III of this part applicable only to CAIR SO2 opt-in 
units under Sec.  96.288(b).
    (iii) The State may decline to adopt the CAIR SO2 opt-in 
provisions of Sec.  96.288(c) of this chapter and the provisions of 
subpart II of this part applicable only to CAIR SO2 opt-in

    (3) A State that adopts an emissions trading program in accordance 
with paragraph (o)(1) or (2) of this section is not required to adopt 
an emissions trading program in accordance with Sec.  96.123 (o)(1) or 
(2) or (aa)(1) or (2) of this chapter.
    (4) If a State adopts an emissions trading program that differs 
substantively from subparts AAA through III of part 96 of this chapter, 
other than as set forth in paragraph (o)(2) of this section, then such 
emissions trading program is not automatically approved as set forth in 
paragraph (o)(1) or (2) of this section and will be reviewed by the 
Administrator for approvability in accordance with the other provisions 
of this section, provided that the SO2 allowances issued 
under such emissions trading program shall not, and the SIP revision 
shall state that such SO2 allowances shall not, qualify as 
CAIR SO2 allowances under any emissions trading program 
approved under paragraph (o)(1) or (2) of this section.
    (p) If a State's SIP revision does not contain an emissions trading 
program approved under paragraph (o)(1) or (2) of this section but 
contains control measures on EGUs as part or all of a State's 
obligation in meeting its requirement under paragraph (a) of this 
section:

    (b) Each revision must provide for periodic reporting by the State 
of SO2 and/or NOX emissions data as specified in 
paragraph (a) of this section to demonstrate whether the State's 
emissions are consistent with the projections contained in its approved 
SIP submission.
    (1) Every-year reporting cycle. As applicable, each revision must 
provide for reporting of SO2 and NOX emissions 
data every year as follows:
    (i) The States identified in paragraph (a)(1) of this section must 
report to EPA annual emissions data every year from all SO2 
and NOX sources within the State for which the State 
specified control measures in its SIP submission under Sec. Sec.  
51.123 and/or 51.124.
    (ii) The States identified in paragraph (a)(2) of this section must 
report to EPA ozone season and summer daily emissions data every year 
from all NOX sources within the State for which the State 
specified control measures in its SIP submission under Sec.  51.123.
    (iii) If sources report SO2 and NOX emissions 
data to EPA in a given year pursuant to a trading program approved 
under Sec.  51.123(o) or Sec.  51.124(o) of this part or pursuant to 
the monitoring and reporting requirements of 40 CFR part 75, then the 
State need not provide annual reporting of these pollutants to EPA for 
such sources.
    (2) Three-year reporting cycle. As applicable, each plan must 
provide for triennial (i.e., every third year) reporting of 
SO2 and NOX emissions data from all sources 
within the State.
    (i) The States identified in paragraph (a)(1) of this section must

followed for all data submitted to meet the requirements of paragraphs 
(b)(1) and (2) of this section.
    (c) The data reported in paragraph (b) of this section must meet 
the requirements of subpart A of this part.
    (d) Approval of annual and ozone season calculation by EPA. Each 
State must submit for EPA approval an example of the calculation 
procedure used to calculate annual and ozone season emissions along 
with sufficient information for EPA to verify the calculated value of 
annual and ozone season emissions.
    (e) Reporting schedules. (1) Reports are to begin with data for 
emissions occurring in the year 2008, which is the first year of the 3-
year cycle.
    (2) After 2008, 3-year cycle reports are to be submitted every 
third year and every-year cycle reports are to be submitted each year 
that a triennial report is not required.

years, in writing by the permitting authority or the Administrator.
    (i) The certificate of representation under Sec.  96.113 for the 
CAIR designated representative for the source and each CAIR 
NOX unit at the source and all documents that demonstrate

NOX unit shall meet the requirements of the CAIR 
NOX Annual Trading Program.
    (2) Any provision of the CAIR NOX Annual Trading Program 
that applies to a CAIR NOX source or the CAIR designated 
representative of a CAIR NOX source shall also apply to the 
owners and operators of such source and of the CAIR NOX

NOX Annual Trading Program, a CAIR permit application, a 
CAIR permit, or an exemption under Sec.  96.105 shall be construed as 
exempting or excluding the owners and operators, and the CAIR 
designated representative, of a CAIR NOX source or CAIR 
NOX unit from compliance with any other provision of the 
applicable, approved State implementation plan, a federally enforceable 
permit, or the Clean Air Act.

    (ii) For units commencing operation on or after January 1, 2001 and 
operating each calendar year during a period of 5 or more consecutive 
calendar years, the average of the 3 highest amounts of the unit's 
total converted control period heat input over the first such 5 years.
    (2)(i) A unit's control period heat input, and a unit's status as 
coal-fired or oil-fired, for a calendar year under paragraph (a)(1)(i) 
of this section, and a unit's total tons of NOX emissions 
during a calendar year under paragraph (c)(3) of this section, will be 
determined in accordance with part 75 of this chapter, to the extent 
the unit was otherwise subject to the requirements of part 75 of this 
chapter for the year, or will be based on the best available data 
reported to the permitting authority for the unit, to the extent the 
unit was not otherwise subject to the requirements of part 75 of this 
chapter for the year.
    (ii) A unit's converted control period heat input for a calendar 
year specified under paragraph (a)(1)(ii) of this section equals:
    (A) Except as provided in paragraph (a)(2)(ii)(B) or (C) of this 
section, the control period gross electrical output of the generator or 
generators served by the unit multiplied by 7,900 Btu/kWh, if the unit 
is coal-fired for the year, or 6,675 Btu/kWh, if the unit is not coal-
fired for the year, and divided by 1,000,000 Btu/mmBtu, provided that 
if a generator is served by 2 or more units, then the gross electrical 
output of the generator will be attributed to each unit in proportion 
to the unit's share of the total control period heat input of such 
units for the year;
    (B) For a unit that is a boiler and has equipment used to produce 
electricity and useful thermal energy for industrial, commercial, 
heating, or cooling purposes through the sequential use of energy, the 
total heat energy (in Btu) of the steam produced by the boiler during 
the control period, divided by 0.8 and by 1,000,000 Btu/mmBtu; or
    (C) For a unit that is a combustion turbine and has equipment used 
to produce electricity and useful thermal energy for industrial, 
commercial, heating, or cooling purposes through the sequential use of 
energy, the control period gross electrical output of the enclosed 
device comprising the compressor, combustor, and turbine multiplied by 
3,414 Btu/kWh, plus the total heat energy (in Btu) of the steam 
produced by any associated heat recovery steam generator during the 
control period divided by 0.8, and with the sum divided by 1,000,000 
Btu/mmBtu.
    (b)(1) For each control period in 2009 and thereafter, the 
permitting authority will allocate to all CAIR NOX units in 
the State that have a baseline heat input (as determined under 
paragraph (a) of this section) a total amount of CAIR NOX 
allowances equal to 95 percent for a control period during 2009 through 
2014, and 97 percent for a control period during 2015 and thereafter, 
of the tons of NOX emissions in the State trading budget 
under Sec.  96.140 (except as provided in paragraph (d) of this section).

[[Page 25350]]

    (2) The permitting authority will allocate CAIR NOX 
allowances to each CAIR NOX unit under paragraph (b)(1) of 
this section in an amount determined by multiplying the total amount of 
CAIR NOX allowances allocated under paragraph (b)(1) of this 
section by the ratio of the baseline heat input of such CAIR 
NOX unit to the total amount of baseline heat input of all 
such CAIR NOX units in the State and rounding to the nearest 
whole allowance as appropriate.
    (c) For each control period in 2009 and thereafter, the permitting 
authority will allocate CAIR NOX allowances to CAIR 
NOX units in the State that commenced operation on or after 
January 1, 2001 and do not yet have a baseline heat input (as 
determined under paragraph (a) of this section), in accordance with the 
following procedures:
    (1) The permitting authority will establish a separate new unit 
set-aside for each control period. Each new unit set-aside will be 
allocated CAIR NOX allowances equal to 5 percent for a 
control period in 2009 through 2013, and 3 percent for a control period 
in 2014 and thereafter, of the amount of tons of NOX 
emissions in the State trading budget under Sec.  96.140.
    (2) The CAIR designated representative of such a CAIR 
NOX unit may submit to the permitting authority a request, 
in a format specified by the permitting authority, to be allocated CAIR 
NOX allowances, starting with the later of the control 
period in 2009 or the first control period after the control period in 
which the CAIR NOX unit commences commercial operation and 
until the first control period for which the unit is allocated CAIR 
NOX allowances under paragraph (b) of this section. The CAIR 
NOX allowance allocation request must be submitted on or 
before July 1 of the first control period for which the CAIR 
NOX allowances are requested and after the date on which the 
CAIR NOX unit commences commercial operation.
    (3) In a CAIR NOX allowance allocation request under 
paragraph (c)(2) of this section, the CAIR designated representative 
may request for a control period CAIR NOX allowances in an 
amount not exceeding the CAIR NOX unit's total tons of 
NOX emissions during the calendar year immediately before 
such control period.
    (4) The permitting authority will review each CAIR NOX 
allowance allocation request under paragraph (c)(2) of this section and 
will allocate CAIR NOX allowances for each control period 
pursuant to such request as follows:
    (i) The permitting authority will accept an allowance allocation 
request only if the request meets, or is adjusted by the permitting 
authority as necessary to meet, the requirements of paragraphs (c)(2) 
and (3) of this section.
    (ii) On or after July 1 of the control period, the permitting 
authority will determine the sum of the CAIR NOX allowances 
requested (as adjusted under paragraph (c)(4)(i) of this section) in 
all allowance allocation requests accepted under paragraph (c)(4)(i) of 
this section for the control period.
    (iii) If the amount of CAIR NOX allowances in the new 
unit set-aside for the control period is greater than or equal to the 
sum under paragraph (c)(4)(ii) of this section, then the permitting 
authority will allocate the amount of CAIR NOX allowances 
requested (as adjusted under paragraph (c)(4)(i) of this section) to 
each CAIR NOX unit covered by an allowance allocation 
request accepted under paragraph (c)(4)(i) of this section.
    (iv) If the amount of CAIR NOX allowances in the new 
unit set-aside for the control period is less than the sum under 
paragraph (c)(4)(ii) of this section, then the permitting authority 
will allocate to each CAIR NOX unit covered by an allowance 
allocation request accepted under paragraph (c)(4)(i) of this section 
the amount of the CAIR NOX allowances requested (as adjusted 
under paragraph (c)(4)(i) of this section), multiplied by the amount of 
CAIR NOX allowances in the new unit set-aside for the 
control period, divided by the sum determined under paragraph 
(c)(4)(ii) of this section, and rounded to the nearest whole allowance 
as appropriate.
    (v) The permitting authority will notify each CAIR designated 
representative that submitted an allowance allocation request of the 
amount of CAIR NOX allowances (if any) allocated for the 
control period to the CAIR NOX unit covered by the request.
    (d) If, after completion of the procedures under paragraph (c)(4) 
of this section for a control period, any unallocated CAIR 
NOX allowances remain in the new unit set-aside for the 
control period, the permitting authority will allocate to each CAIR 
NOX unit that was allocated CAIR NOX allowances 
under paragraph (b) of this section an amount of CAIR NOX 
allowances equal to the total amount of such remaining unallocated CAIR 
NOX allowances, multiplied by the unit's allocation under 
paragraph (b) of this section, divided by 95 percent for a control 
period during 2009 through 2014, and 97 percent for a control period 
during 2015 and thereafter, of the amount of tons of NOX 
emissions in the State trading budget under Sec.  96.140, and rounded 
to the nearest whole allowance as appropriate.

Sec.  96.143  Compliance supplement pool.

    (a) In addition to the CAIR NOX allowances allocated 
under Sec.  96.142, the permitting authority may allocate for the 
control period in 2009 up to the following amount of CAIR 
NOX allowances to CAIR NOX units in the 
respective State:

    (b) For any CAIR NOX unit in the State that achieves 
NOX emission reductions in 2007 and 2008 that are not 
necessary to comply with any State or federal emissions limitation 
applicable during such years, the CAIR designated representative of the 
unit may request early reduction credits, and allocation of CAIR 
NOX allowances from the compliance supplement pool under 
paragraph (a) of this section for such early reduction credits, in 
accordance with the following:
    (1) The owners and operators of such CAIR NOX unit shall 
monitor and report the NOX emissions rate and the heat input 
of the unit in accordance with subpart HH of this part in each control 
period for which early reduction credit is requested.
    (2) The CAIR designated representative of such CAIR NOX 
unit shall submit to the permitting authority by July 1, 2009 a 
request, in a format specified by the permitting authority, for 
allocation of an amount of CAIR NOX allowances from the 
compliance supplement pool not exceeding the sum of the amounts (in 
tons) of the unit's

[[Page 25351]]

NOX emission reductions in 2007 and 2008 that are not 
necessary to comply with any State or federal emissions limitation 
applicable during such years, determined in accordance with subpart HH 
of this part.
    (c) For any CAIR NOX unit in the State whose compliance 
with CAIR NOX emissions limitation for the control period in 
2009 would create an undue risk to the reliability of electricity 
supply during such control period, the CAIR designated representative 
of the unit may request the allocation of CAIR NOX 
allowances from the compliance supplement pool under paragraph (a) of 
this section, in accordance with the following:
    (1) The CAIR designated representative of such CAIR NOX 
unit shall submit to the permitting authority by July 1, 2009 a 
request, in a format specified by the permitting authority, for 
allocation of an amount of CAIR NOX allowances from the 
compliance supplement pool not exceeding the minimum amount of CAIR 
NOX allowances necessary to remove such undue risk to the 
reliability of electricity supply.
    (2) In the request under paragraph (c)(1) of this section, the CAIR 
designated representative of such CAIR NOX unit shall 
demonstrate that, in the absence of allocation to the unit of the 
amount of CAIR NOX allowances requested, the unit's 
compliance with CAIR NOX emissions limitation for the 
control period in 2009 would create an undue risk to the reliability of 
electricity supply during such control period. This demonstration must 
include a showing that it would not be feasible for the owners and 
operators of the unit to:
    (i) Obtain a sufficient amount of electricity from other 
electricity generation facilities, during the installation of control 
technology at the unit for compliance with the CAIR NOX 
emissions limitation, to prevent such undue risk; or
    (ii) Obtain under paragraphs (b) and (d) of this section, or 
otherwise obtain, a sufficient amount of CAIR NOX allowances 
to prevent such undue risk.
    (d) The permitting authority will review each request under 
paragraph (b) or (c) of this section submitted by July 1, 2009 and will 
allocate CAIR NOX allowances for the control period in 2009 
to CAIR NOX units in the State and covered by such request 
as follows:
    (1) Upon receipt of each such request, the permitting authority 
will make any necessary adjustments to the request to ensure that the 
amount of the CAIR NOX allowances requested meets the 
requirements of paragraph (b) or (c) of this section.
    (2) If the State's compliance supplement pool under paragraph (a) 
of this section has an amount of CAIR NOX allowances not 
less than the total amount of CAIR NOX allowances in all 
such requests (as adjusted under paragraph (d)(1) of this section), the 
permitting authority will allocate to each CAIR NOX unit 
covered by such requests the amount of CAIR NOX allowances 
requested (as adjusted under paragraph (d)(1) of this section).
    (3) If the State's compliance supplement pool under paragraph (a) 
of this section has a smaller amount of CAIR NOX allowances 
than the total amount of CAIR NOX allowances in all such 
requests (as adjusted under paragraph (d)(1) of this section), the 
permitting authority will allocate CAIR NOX allowances to 
each CAIR NOX unit covered by such requests according to the 
following formula and rounding to the nearest whole allowance as 
appropriate:

Unit's allocation = Unit's adjusted allocation x (State's compliance 
supplement pool / Total adjusted allocations for all units)

Where:

    ``Unit's allocation'' is the number of CAIR NOX 
allowances allocated to the unit from the State's compliance supplement 
pool. Unit's adjusted allocation'' is the amount of CAIR NOX 
allowances requested for the unit under paragraph (b) or (c) of this 
section, as adjusted under paragraph (d)(1) of this section. ``State's 
compliance supplement pool'' is the amount of CAIR NOX 
allowances in the State's compliance supplement pool. ``Total adjusted 
allocations for all units'' is the sum of the amounts of allocations 
requested for all units under paragraph (b) or (c) of this section, as 
adjusted under paragraph (d)(1) of this section.
    (4) By November 30, 2009, the permitting authority will determine, 
and submit to the Administrator, the allocations under paragraph (d)(3) 
or (4) of this section.
    (5) By January 1, 2010, the Administrator will record the 
allocations under paragraph (d)(5) of this section.

Sec.  96.152  Responsibilities of CAIR authorized account 
representative.

    Following the establishment of a CAIR NOX Allowance 
Tracking System account, all submissions to the Administrator 
pertaining to the account, including, but not limited to, submissions 
concerning the deduction or transfer of CAIR NOX allowances 
in the account, shall be made only by the CAIR authorized account 
representative for the account.

Sec.  96.153  Recordation of CAIR NOX allowance allocations.

    (a) By December 1, 2006, the Administrator will record in the CAIR 
NOX source's compliance account the CAIR NOX 
allowances allocated for the CAIR NOX units at a source, as 
submitted by the permitting authority in accordance with Sec.  
96.141(a), for the control periods in 2009, 2010, 2011, 2012, 2013, and 
2014.
    (b) By December 1, 2009, the Administrator will record in the CAIR 
NOX source's compliance account the CAIR NOX 
allowances allocated for the CAIR NOX units at the source, 
as submitted by the permitting authority or as determined by the 
Administrator in accordance with Sec.  96.141(b), for the control 
period in 2015.
    (c) In 2011 and each year thereafter, after the Administrator has 
made all deductions (if any) from a CAIR NOX source's 
compliance account under Sec.  96.154, the Administrator will record in 
the CAIR NOX source's compliance account the CAIR 
NOX allowances allocated for the CAIR NOX units 
at the source, as submitted by the permitting authority or determined 
by the Administrator in accordance with Sec.  96.141(b), for the 
control period in the sixth year after the year of the control period 
for which such deductions were or could have been made.
    (d) By December 1, 2009 and December 1 of each year thereafter, the 
Administrator will record in the CAIR NOX source's 
compliance account the CAIR NOX allowances allocated for the 
CAIR NOX units at the source, as submitted by the permitting 
authority or determined by the Administrator in accordance with Sec.  
96.141(c), for the control period in the year of the applicable 
deadline for recordation under this paragraph.
    (e) Serial numbers for allocated CAIR NOX allowances. When 
recording the allocation of CAIR NOX allowances for a CAIR 
NOX unit in a compliance account, the Administrator will 
assign each CAIR NOX allowance a unique identification 
number that will include digits identifying the year of the control 
period for which the CAIR NOX allowance is allocated.

Sec.  96.154  Compliance with CAIR NOX emissions limitation.

    (a) Allowance transfer deadline. The CAIR NOX allowances 
are available to be deducted for compliance with a source's CAIR 
NOX emissions limitation for a control period in a given 
calendar year only if the CAIR NOX allowances:
    (1) Were allocated for the control period in the year or a prior 
year;
    (2) Are held in the compliance account as of the allowance transfer 
deadline for the control period or are transferred into the compliance 
account by a CAIR NOX allowance transfer correctly submitted 
for recordation under Sec.  96.160 by the allowance transfer deadline 
for the control period; and
    (3) Are not necessary for deductions for excess emissions for a 
prior control period under paragraph (d) of this section.
    (b) Deductions for compliance. Following the recordation, in 
accordance with Sec.  96.161, of CAIR NOX allowance 
transfers submitted for recordation in a source's compliance account by 
the allowance transfer deadline for a control period, the Administrator 
will deduct from the compliance account CAIR NOX allowances 
available under paragraph (a) of this section in order to determine 
whether the source meets the CAIR NOX emissions limitation 
for the control period, as follows:
    (1) Until the amount of CAIR NOX allowances deducted 
equals the number of tons of total nitrogen oxides emissions, 
determined in accordance with subpart HH of this part, from all CAIR

NOX monitoring system under appendix E to part 75 of this 
chapter, under Sec.  96.170(a)(1) are subject to the recertification 
requirements in Sec.  75.20(g)(6) of this chapter.
    (3) Approval process for initial certification and recertification. 
Paragraphs (d)(3)(i) through (iv) of this section apply to both initial 
certification and recertification of a continuous monitoring system 
under Sec.  96.170(a)(1). For recertifications, replace the words 
``certification'' and ``initial certification'' with the word 
``recertification'', replace the word ``certified'' with the word 
``recertified,'' and follow the procedures in Sec. Sec.  75.20(b)(5) 
and (g)(7) of this chapter in lieu of the procedures in paragraph 
(d)(3)(v) of this section.
    (i) Notification of certification. The CAIR designated 
representative shall submit to the permitting authority, the 
appropriate EPA Regional Office, and the Administrator written notice 
of the dates of certification testing, in accordance with Sec.  96.173.
    (ii) Certification application. The CAIR designated representative 
shall submit to the permitting authority a certification application 
for each monitoring system. A complete certification application shall

    (iii) Provisional certification date. The provisional certification 
date for a monitoring system shall be determined in accordance with 
Sec.  75.20(a)(3) of this chapter. A provisionally certified monitoring 
system may be used under the CAIR NOX Annual Trading Program 
for a period not to exceed 120 days after receipt by the permitting 
authority of the complete certification application for the monitoring 
system under paragraph (d)(3)(ii) of this section. Data measured and 
recorded by the provisionally certified monitoring system, in 
accordance with the requirements of part 75 of this chapter, will be 
considered valid quality-assured data (retroactive to the date and time 
of provisional certification), provided that the permitting authority 
does not invalidate the provisional certification by issuing a notice 
of disapproval within 120 days of the date of receipt of the complete 
certification application by the permitting authority.
    (iv) Certification application approval process. The permitting 
authority will issue a written notice of approval or disapproval of the 
certification application to the owner or operator within 120 days of 
receipt of the complete certification application under paragraph 
(d)(3)(ii) of this section. In the event the permitting authority does 
not issue such a notice within such 120-day period, each monitoring 
system that meets the applicable performance requirements of part 75 of 
this chapter and is included in the certification application will be 
deemed certified for use under the CAIR NOX Annual Trading 
Program.
    (A) Approval notice. If the certification application is complete 
and shows that each monitoring system meets the applicable performance 
requirements of part 75 of this chapter, then the permitting authority 
will issue a written notice of approval of the certification 
application within 120 days of receipt.
    (B) Incomplete application notice. If the certification application 
is not complete, then the permitting authority will issue a written 
notice of incompleteness that sets a reasonable date by which the CAIR 
designated representative must submit the additional information 
required to complete the certification application. If the CAIR 
designated representative does not comply with the notice of 
incompleteness by the specified date, then the permitting authority may 
issue a notice of disapproval under paragraph (d)(3)(iv)(C) of this 
section. The 120-day review period shall not begin before receipt of a 
complete certification application.
    (C) Disapproval notice. If the certification application shows that 
any monitoring system does not meet the performance requirements of 
part 75 of this chapter or if the certification application is 
incomplete and the requirement for disapproval under paragraph 
(d)(3)(iv)(B) of this section is met, then the permitting authority 
will issue a written notice of disapproval of the certification 
application. Upon issuance of such notice of disapproval, the 
provisional certification is invalidated by the permitting authority 
and the data measured and recorded by each uncertified monitoring 
system shall not be considered valid quality-assured data beginning 
with the date and hour of provisional certification (as defined under 
Sec.  75.20(a)(3) of this chapter). The owner or operator shall follow 
the procedures for loss of certification in paragraph (d)(3)(v) of this 
section for each monitoring system that is disapproved for initial 
certification.
    (D) Audit decertification. The permitting authority or, for a CAIR 
NOX opt-in unit or a unit for which a CAIR opt-in permit 
application is submitted and not withdrawn and a CAIR opt-in permit is 
not yet issued or denied under subpart II of this part, the 
Administrator may issue a notice of disapproval of the certification 
status of a monitor in accordance with Sec.  96.172(b).
    (v) Procedures for loss of certification. If the permitting 
authority or the Administrator issues a notice of disapproval of a 
certification application under paragraph (d)(3)(iv)(C) of this section 
or a notice of disapproval of certification status under paragraph 
(d)(3)(iv)(D) of this section, then:
    (A) The owner or operator shall substitute the following values, 
for each disapproved monitoring system, for each hour of unit operation 
during the period of invalid data specified under Sec.  
75.20(a)(4)(iii), Sec.  75.20(g)(7), or Sec.  75.21(e) of this chapter 
and continuing until the applicable date and hour specified under Sec.  
75.20(a)(5)(i) or (g)(7) of this chapter:
    (1) For a disapproved NOX emission rate (i.e., 
NOX-diluent) system, the maximum potential NOX 
emission rate, as defined in Sec.  72.2 of this chapter.
    (2) For a disapproved NOX pollutant concentration 
monitor and disapproved flow monitor, respectively, the maximum 
potential concentration of NOX and the maximum potential 
flow rate, as defined in sections 2.1.2.1 and 2.1.4.1 of appendix A to 
part 75 of this chapter.
    (3) For a disapproved moisture monitoring system and disapproved 
diluent gas monitoring system, respectively, the minimum potential 
moisture percentage and either the maximum potential CO2 
concentration or the minimum potential O2

[[Page 25357]]

concentration (as applicable), as defined in sections 2.1.5, 2.1.3.1, 
and 2.1.3.2 of appendix A to part 75 of this chapter.
    (4) For a disapproved fuel flowmeter system, the maximum potential 
fuel flow rate, as defined in section 2.4.2.1 of appendix D to part 75 
of this chapter.
    (5) For a disapproved excepted NOX monitoring system 
under appendix E to part 75 of this chapter, the fuel-specific maximum 
potential NOX emission rate, as defined in Sec.  72.2 of 
this chapter.
    (B) The CAIR designated representative shall submit a notification 
of certification retest dates and a new certification application in 
accordance with paragraphs (d)(3)(i) and (ii) of this section.
    (C) The owner or operator shall repeat all certification tests or 
other requirements that were failed by the monitoring system, as 
indicated in the permitting authority's or the Administrator's notice 
of disapproval, no later than 30 unit operating days after the date of 
issuance of the notice of disapproval.
    (e) Initial certification and recertification procedures for units 
using the low mass emission excepted methodology under Sec.  75.19 of 
this chapter. The owner or operator of a unit qualified to use the low 
mass emissions (LME) excepted methodology under Sec.  75.19 of this 
chapter shall meet the applicable certification and recertification 
requirements in Sec. Sec.  75.19(a)(2) and 75.20(h) of this chapter. If 
the owner or operator of such a unit elects to certify a fuel flowmeter 
system for heat input determination, the owner or operator shall also 
meet the certification and recertification requirements in Sec.  
75.20(g) of this chapter.
    (f) Certification/recertification procedures for alternative 
monitoring systems. The CAIR designated representative of each unit for 
which the owner or operator intends to use an alternative monitoring 
system approved by the Administrator and, if applicable, the permitting 
authority under subpart E of part 75 of this chapter shall comply with 
the applicable notification and application procedures of Sec.  
75.20(f) of this chapter.

Sec.  96.172  Out of control periods.

    (a) Whenever any monitoring system fails to meet the quality-
assurance and quality-control requirements or data validation 
requirements of part 75 of this chapter, data shall be substituted 
using the applicable missing data procedures in subpart D or subpart H 
of, or appendix D or appendix E to, part 75 of this chapter.
    (b) Audit decertification. Whenever both an audit of a monitoring 
system and a review of the initial certification or recertification 
application reveal that any monitoring system should not have been 
certified or recertified because it did not meet a particular 
performance specification or other requirement under Sec.  96.171 or 
the applicable provisions of part 75 of this chapter, both at the time 
of the initial certification or recertification application submission 
and at the time of the audit, the permitting authority or, for a CAIR 
NOX opt-in unit or a unit for which a CAIR opt-in permit 
application is submitted and not withdrawn and a CAIR opt-in permit is 
not yet issued or denied under subpart II of this part, the 
Administrator will issue a notice of disapproval of the certification 
status of such monitoring system. For the purposes of this paragraph, 
an audit shall be either a field audit or an audit of any information 
submitted to the permitting authority or the Administrator. By issuing 
the notice of disapproval, the permitting authority or the 
Administrator revokes prospectively the certification status of the 
monitoring system. The data measured and recorded by the monitoring 
system shall not be considered valid quality-assured data from the date 
of issuance of the notification of the revoked certification status 
until the date and time that the owner or operator completes 
subsequently approved initial certification or recertification tests 
for the monitoring system. The owner or operator shall follow the

Sec.  96.184  Opt-in process.

    The permitting authority will issue or deny a CAIR opt-in permit 
for a unit for which an initial application for a CAIR

[[Page 25359]]

opt-in permit under Sec.  96.183 is submitted in accordance with the 
following:
    (a) Interim review of monitoring plan. The permitting authority and 
the Administrator will determine, on an interim basis, the sufficiency 
of the monitoring plan accompanying the initial application for a CAIR 
opt-in permit under Sec.  96.183. A monitoring plan is sufficient, for 
purposes of interim review, if the plan appears to contain information 
demonstrating that the NOX emissions rate and heat input of 
the unit and all other applicable parameters are monitored and reported 
in accordance with subpart HH of this part. A determination of 
sufficiency shall not be construed as acceptance or approval of the 
monitoring plan.
    (b) Monitoring and reporting. (1)(i) If the permitting authority 
and the Administrator determine that the monitoring plan is sufficient 
under paragraph (a) of this section, the owner or operator shall 
monitor and report the NOX emissions rate and the heat input 
of the unit and all other applicable parameters, in accordance with 
subpart HH of this part, starting on the date of certification of the 
appropriate monitoring systems under subpart HH of this part and 
continuing until a CAIR opt-in permit is denied under Sec.  96.184(f) 
or, if a CAIR opt-in permit is issued, the date and time when the unit 
is withdrawn from the CAIR NOX Annual Trading Program in 
accordance with Sec.  96.186.
    (ii) The monitoring and reporting under paragraph (b)(1)(i) of this 
section shall include the entire control period immediately before the 
date on which the unit enters the CAIR NOX Annual Trading 
Program under Sec.  96.184(g), during which period monitoring system 
availability must not be less than 90 percent under subpart HH of this 
part and the unit must be in full compliance with any applicable State 
or Federal emissions or emissions-related requirements.
    (2) To the extent the NOX emissions rate and the heat 
input of the unit are monitored and reported in accordance with subpart 
HH of this part for one or more control periods, in addition to the 
control period under paragraph (b)(1)(ii) of this section, during which 
control periods monitoring system availability is not less than 90 
percent under subpart HH of this part and the unit is in full 
compliance with any applicable State or Federal emissions or emissions-
related requirements and which control periods begin not more than 3 
years before the unit enters the CAIR NOX Annual Trading 
Program under Sec.  96.184(g), such information shall be used as 
provided in paragraphs (c) and (d) of this section.
    (c) Baseline heat input. The unit's baseline heat rate shall equal:
    (1) If the unit's NOX emissions rate and heat input are 
monitored and reported for only one control period, in accordance with 
paragraph (b)(1) of this section, the unit's total heat input (in 
mmBtu) for the control period; or
    (2) If the unit's NOX emissions rate and heat input are 
monitored and reported for more than one control period, in accordance 
with paragraphs (b)(1) and (2) of this section, the average of the 
amounts of the unit's total heat input (in mmBtu) for the control 
period under paragraph (b)(1)(ii) of this section and for the control 
periods under paragraph (b)(2) of this section.
    (d) Baseline NOX emission rate. The unit's baseline 
NOX emission rate shall equal:
    (1) If the unit's NOX emissions rate and heat input are 
monitored and reported for only one control period, in accordance with 
paragraph (b)(1) of this section, the unit's NOX emissions 
rate (in lb/mmBtu) for the control period;
    (2) If the unit's NOX emissions rate and heat input are 
monitored and reported for more than one control period, in accordance 
with paragraphs (b)(1) and (2) of this section, and the unit does not 
have add-on NOX emission controls during any such control 
periods, the average of the amounts of the unit's NOX 
emissions rate (in lb/mmBtu) for the control period under paragraph 
(b)(1)(ii) of this section and the control periods under paragraph 
(b)(2) of this section; or
    (3) If the unit's NOX emissions rate and heat input are 
monitored and reported for more than one control period, in accordance 
with paragraphs (b)(1) and (2) of this section, and the unit has add-on 
NOX emission controls during any such control periods, the 
average of the amounts of the unit's NOX emissions rate (in 
lb/mmBtu) for such control period during which the unit has add-on 
NOX emission controls.
    (e)  Issuance of CAIR opt-in permit. After calculating the baseline 
heat input and the baseline NOX emissions rate for the unit 
under paragraphs (c) and (d) of this section and if the permitting 
authority determines that the CAIR designated representative shows that 
the unit meets the requirements for a CAIR NOX opt-in unit 
in Sec.  96.180 and meets the elements certified in Sec.  96.183(a)(2), 
the permitting authority will issue a CAIR opt-in permit. The 
permitting authority will provide a copy of the CAIR opt-in permit to 
the Administrator, who will then establish a compliance account for the 
source that includes the CAIR NOX opt-in unit unless the 
source already has a compliance account.
    (f) Issuance of denial of CAIR opt-in permit. Notwithstanding 
paragraphs (a) through (e) of this section, if at any time before 
issuance of a CAIR opt-in permit for the unit, the permitting authority 
determines that the CAIR designated representative fails to show that 
the unit meets the requirements for a CAIR NOX opt-in unit 
in Sec.  96.180 or meets the elements certified in Sec.  96.183(a)(2), 
the permitting authority will issue a denial of a CAIR NOX 
opt-in permit for the unit.
    (g) Date of entry into CAIR NOX Annual Trading Program. 
A unit for which an initial CAIR opt-in permit is issued by the 
permitting authority shall become a CAIR NOX opt-in unit, 
and a CAIR NOX unit, as of the later of January 1, 2009 or 
January 1 of the first control period during which such CAIR opt-in 
permit is issued.
    (h) Repowered CAIR NOX opt-in unit. (1) If CAIR 
designated representative requests, and the permitting authority issues 
a CAIR opt-in permit providing for, allocation to a CAIR NOX 
opt-in unit of CAIR NOX allowances under Sec.  96.188(c) and 
such unit is repowered after its date of entry into the CAIR 
NOX Annual Trading Program under paragraph (g) of this 
section, the repowered unit shall be treated as a CAIR NOX 
opt-in unit replacing the original CAIR NOX opt-in unit, as 
of the date of start-up of the repowered unit's combustion chamber.
    (2) Notwithstanding paragraphs (c) and (d) of this section, as of 
the date of start-up under paragraph (h)(1) of this section, the 
repowered unit shall be deemed to have the same date of commencement of 
operation, date of commencement of commercial operation, baseline heat 
input, and baseline NOX emission rate as the original CAIR 
NOX opt-in unit, and the original CAIR NOX opt-in 
unit shall no longer be treated as a CAIR opt-in unit or a CAIR 
NOX unit.

Sec.  96.185  CAIR opt-in permit contents.

    (a) Each CAIR opt-in permit will contain:
    (1) All elements required for a complete CAIR permit application 
under Sec.  96.122;
    (2) The certification in Sec.  96.183(a)(2);
    (3) The unit's baseline heat input under Sec.  96.184(c);

[[Page 25360]]

conditions in Sec. Sec.  96.184(h) and 96.186(g));
    (6) A statement that the unit may withdraw from the CAIR 
NOX Annual Trading Program only in accordance with Sec.  
96.186; and
    (7) A statement that the unit is subject to, and the owners and 
operators of the unit must comply with, the requirements of Sec.  96.187.
    (b) Each CAIR opt-in permit is deemed to incorporate automatically 
the definitions of terms under Sec.  96.102 and, upon recordation by 
the Administrator under subpart FF or GG of this part or this subpart, 
every allocation, transfer, or deduction of CAIR NOX 
allowances to or from the compliance account of the source that 
includes a CAIR NOX opt-in unit covered by the CAIR opt-in 
permit.

Sec.  96.186  Withdrawal from CAIR NOX Annual Trading Program.

    Except as provided under paragraph (g) of this section, a CAIR 
NOX opt-in unit may withdraw from the CAIR NOX 
Annual Trading Program, but only if the permitting authority issues a 
notification to the CAIR designated representative of the CAIR 
NOX opt-in unit of the acceptance of the withdrawal of the 
CAIR NOX opt-in unit in accordance with paragraph (d) of 
this section.
    (a) Requesting withdrawal. In order to withdraw a CAIR opt-in unit 
from the CAIR NOX Annual Trading Program, the CAIR 
designated representative of the CAIR NOX opt-in unit shall 
submit to the permitting authority a request to withdraw effective as 
of midnight of December 31 of a specified calendar year, which date 
must be at least 4 years after December 31 of the year of entry into 
the CAIR NOX Annual Trading Program under Sec.  96.184(g). 
The request must be submitted no later than 90 days before the 
requested effective date of withdrawal.
    (b) Conditions for withdrawal. Before a CAIR NOX opt-in 
unit covered by a request under paragraph (a) of this section may 
withdraw from the CAIR NOX Annual Trading Program and the 
CAIR opt-in permit may be terminated under paragraph (e) of this 
section, the following conditions must be met:
    (1) For the control period ending on the date on which the 
withdrawal is to be effective, the source that includes the CAIR 
NOX opt-in unit must meet the requirement to hold CAIR 
NOX allowances under Sec.  96.106(c) and cannot have any 
excess emissions.
    (2) After the requirement for withdrawal under paragraph (b)(1) of 
this section is met, the Administrator will deduct from the compliance 
account of the source that includes the CAIR NOX opt-in unit 
CAIR NOX allowances equal in number to and allocated for the 
same or a prior control period as any CAIR NOX allowances 
allocated to the CAIR NOX opt-in unit under Sec.  96.188 for 
any control period for which the withdrawal is to be effective. If 
there are no remaining CAIR NOX units at the source, the 
Administrator will close the compliance account, and the owners and 
operators of the CAIR NOX opt-in unit may submit a CAIR 
NOX allowance transfer for any remaining CAIR NOX 
allowances to another CAIR NOX Allowance Tracking System in 
accordance with subpart GG of this part.
    (c) Notification. (1) After the requirements for withdrawal under 
paragraphs (a) and (b) of this section are met (including deduction of 
the full amount of CAIR NOX allowances required), the 
permitting authority will issue a notification to the CAIR designated 
representative of the CAIR NOX opt-in unit of the acceptance 
of the withdrawal of the CAIR NOX opt-in unit as of midnight 
on December 31 of the calendar year for which the withdrawal was 
requested.
    (2) If the requirements for withdrawal under paragraphs (a) and (b) 
of this section are not met, the permitting authority will issue a 
notification to the CAIR designated representative of the CAIR 
NOX opt-in unit that the CAIR NOX opt-in unit's 
request to withdraw is denied. Such CAIR NOX opt-in unit 
shall continue to be a CAIR NOX opt-in unit.
    (d) Permit amendment. After the permitting authority issues a 
notification under paragraph (c)(1) of this section that the 
requirements for withdrawal have been met, the permitting authority 
will revise the CAIR permit covering the CAIR NOX opt-in 
unit to terminate the CAIR opt-in permit for such unit as of the 
effective date specified under paragraph (c)(1) of this section. The 
unit shall continue to be a CAIR NOX opt-in unit until the 
effective date of the termination and shall comply with all 
requirements under the CAIR NOX Annual Trading Program 
concerning any control periods for which the unit is a CAIR 
NOX opt-in unit, even if such requirements arise or must be 
complied with after the withdrawal takes effect.
    (e) Reapplication upon failure to meet conditions of withdrawal. If 
the permitting authority denies the CAIR NOX opt-in unit's 
request to withdraw, the CAIR designated representative may submit 
another request to withdraw in accordance with paragraphs (a) and (b) 
of this section.
    (f) Ability to reapply to the CAIR NOX Annual Trading 
Program. Once a CAIR NOX opt-in unit withdraws from the CAIR 
NOX Annual Trading Program and its CAIR opt-in permit is 
terminated under this section, the CAIR designated representative may 
not submit another application for a CAIR opt-in permit under Sec.  
96.183 for such CAIR NOX opt-in unit before the date that is 
4 years after the date on which the withdrawal became effective. Such 
new application for a CAIR opt-in permit will be treated as an initial 
application for a CAIR opt-in permit under Sec.  96.184.
    (g) Inability to withdraw. Notwithstanding paragraphs (a) through 
(f) of this section, a CAIR NOX opt-in unit shall not be 
eligible to withdraw from the CAIR NOX Annual Trading 
Program if the CAIR designated representative of the CAIR 
NOX opt-in unit requests, and the permitting authority 
issues a CAIR NOX opt-in permit providing for, allocation to 
the CAIR NOX opt-in unit of CAIR NOX allowances 
under Sec.  96.188(c).

Sec.  96.187  Change in regulatory status.

    (a) Notification. If a CAIR NOX opt-in unit becomes a 
CAIR NOX unit under Sec.  96.104, then the CAIR designated 
representative shall notify in writing the permitting authority and the 
Administrator of such change in the CAIR NOX opt-in unit's 
regulatory status, within 30 days of such change.
    (b) Permitting authority's and Administrator's actions.
    (1) If a CAIR NOX opt-in unit becomes a CAIR 
NOX unit under Sec.  96.104, the permitting authority will 
revise the CAIR NOX opt-in unit's CAIR opt-in permit to meet 
the requirements of a CAIR permit under Sec.  96.123 as of the date on 
which the CAIR NOX opt-in unit becomes a CAIR NOX 
unit under Sec.  96.104.
    (2)(i) The Administrator will deduct from the compliance account of 
the source that includes the CAIR NOX opt-in unit that 
becomes a CAIR NOX unit under Sec.  96.104, CAIR 
NOX allowances equal in number to and allocated for the same 
or a prior control period as:
    (A) Any CAIR NOX allowances allocated to the CAIR 
NOX opt-in unit under Sec.  96.188 for any control period 
after the date on which the CAIR NOX opt-in unit becomes a 
CAIR NOX unit under Sec.  96.104; and
    (B) If the date on which the CAIR NOX opt-in unit 
becomes a CAIR NOX unit under Sec.  96.104 is not December 
31, the CAIR NOX allowances allocated to the CAIR 
NOX opt-in unit under Sec.  96.188 for the control period 
that includes the date on which the CAIR NOX opt-in unit 
becomes a CAIR NOX unit under
