SUPPLEMENTARY INFORMATION:
I. EPA's Action
A. What Action Is EPA Proposing Today?
EPA is proposing to approve, in its entirety, the Visible Emissions
portion of the SIP revision submitted on December 14, 2004, by the
State of North Carolina. The language in this submittal replaces all
prior versions of rule NCAC 2D .0521 Visible Emissions submitted to EPA.
B. Why Is EPA Proposing This Action?
On April 16, 2001, the North Carolina Department of Environment and
Natural Resources submitted to EPA a revision to the North Carolina SIP
modifying rule NCAC 2D .0521 Visible Emissions. In a letter dated March
29, 2002, EPA provided comments to North Carolina explaining additional
requirements that must be met in order for EPA to approve this rule.
These requirements included the submittal of a demonstration proving
that such an exemption would not violate the National Ambient Air
Quality Standards. On July 10, 2002, North Carolina submitted a
demonstration to EPA they believed to address the ``worst case'' for
air quality. A proposed rule and direct final rule were published June
6, 2003, (see 68 FR 33898 and 68 FR 33873) approving the SIP revision
submitted by the North Carolina Department of Environment and Natural
Resources on April 16, 2001, for the purpose of amending rule NCAC 2D
.0521 Visible Emissions. Due to adverse comment, EPA withdrew the
direct final rule on August 5, 2003, (see 68 FR 46101). In the interim,
on April 4, 2003, the North Carolina Department of Environment and
Natural Resources submitted to EPA another SIP revision that included
additional changes to the Visible Emissions rule. EPA approved the
April 4, 2003, submittal with the exception of the Visible Emissions
portion.
On October 14, 2004, and then again on December 14, 2004, the North
Carolina Department of Environment and Natural Resources submitted to
EPA revisions to the North Carolina SIP. EPA is proposing to approve
the version of the NCAC 2D.0521, in its entirety, as submitted December
14, 2004, and does not intend to act on previous versions of the rule.
In the December 14, 2004 submittal, the State of North Carolina
requested adoption of new rules and amendments to existing rules
including NCAC 2D.0521 Visible Emissions. Today's Federal Register
notice addresses only the NCAC 2D .0521 Visible Emissions portion of
the December 14, 2004, submittal. Action on the remaining portions of
that submittal will be taken in a separate notice.
The purpose of the amendment to rule .0521 is to include the
following changes:
1. The existing Visible Emissions rule exempts start-ups made
according to procedures approved under rule NCAC 2D .0535. Rule NCAC 2D
.0535 includes start-ups, shutdowns and malfunctions. An exemption for
shutdowns and malfunctions was added to rule NCAC 2D .0521 to be
consistent with the already existing rule, NCAC 2D .0535.
2. The revised rule states that sources subject to a visible
emission standard in NCAC 2D .0506, Particulates from Hot Mix Asphalt
Plants, shall meet that standard instead of the standard found in this
revised NCAC 2D .0521. The revised rule also states that sources
subject to a visible emission standard in NCAC 2D .0543, .0544, .1205,
.1206 and .1210, shall meet their respective standards instead of the
standard found in this revised NCAC 2D .0521. With the exception of
NCAC 2D .0506, these rules are not part of the federally approved SIP
and are not applicable to today's action.
3. An exemption for engine maintenance and testing controls where
visible emissions controls are infeasible was added to rule NCAC 2D
.0535. This exemption applies to maintenance and repair on engines in
order for diagnostics to be performed. The exemption does not apply,
however, to the testing of peak shaving and emergency generators. The
rule also states that the Director shall consider emissions, capital
cost of compliance, annual incremental compliance cost and
environmental and health impacts in deciding if controls are infeasible.
4. The revised rule has changed from stating that sources
manufactured after July 1, 1971 ``may'' be allowed to ``shall'' be
allowed a 40 percent opacity when averaged over a six-minute period and
allowed to exceed a 40 percent opacity under certain conditions if the
source demonstrates compliance with mass emissions standards and
compliance with the National Ambient Air Quality Standards (NAAQS).
5. The revised rule provides sources required to install, operate
and maintain continuous opacity monitors (COMs), the ability to comply
with the visible emissions rule by allowing these sources to aggregate
exceedences on a daily basis rather than being restricted to one
exceedence per hour. Specifically, under the new amendment, sources
with COMs are allowed no more than 4 six-minute periods to exceed the
opacity standard in any one day provided that no excess emissions
exempted here cause or contribute to a violation of any mass emission
standard or any ambient air quality standard. The new amendment also
requires that the percent of excess emissions shall not exceed 0.8
percent of the total operating hours in a calendar quarter. This
restriction adds a quarterly cap on exemptions that is more restrictive
than the four six minute exemptions per day. Exceedences of the opacity
limit greater than 0.8 percent of the total operating hours will be
considered a violation of this rule.
On April 15, 2005 North Carolina sent EPA a letter stating that any
revised standards issued by North Carolina, pursuant to NCAC 2D .0521,
.0606, and .0608, shall be submitted to EPA to be approved as revisions
to the federally-enforceable SIP. The letter also states that North
Carolina understands that EPA can continue to enforce the current SIP
standard until such time as EPA approves any new standard generated
pursuant to NCAC 2D .0521, .0606 or .0608 as part of the federally-
enforceable SIP.
II. Proposed Action
EPA is proposing to approve, in its entirety, the Visible Emissions
portion of a SIP revision submitted to EPA by the State of North
Carolina on December 14, 2004.
Statutory and Executive Order Reviews: Under Executive Order 12866
(58 FR 51735, October 4, 1993), this proposed action is not a
``significant regulatory action'' and therefore is not subject to
review by the Office of Management and Budget. For this reason, this
action is also not subject to Executive Order 13211, ``Actions
Concerning Regulations That Significantly Affect Energy Supply,
Distribution, or Use'' (66 FR 28355, May 22, 2001). This proposed
action merely proposes to approve state law as meeting Federal
requirements and imposes no additional requirements beyond those
imposed by state law. Accordingly, the Administrator certifies that
this proposed rule will not have a
[[Page 28497]]
significant economic impact on a substantial number of small entities
under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because
this rule proposes to approve pre-existing requirements under state law
and does not impose any additional enforceable duty beyond that
required by state law, it does not contain any unfunded mandate or
significantly or uniquely affect small governments, as described in the
Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4).
This proposed rule also does not have tribal implications because
it will not have a substantial direct effect on one or more Indian
tribes, on the relationship between the Federal Government and Indian
tribes, or on the distribution of power and responsibilities between
the Federal Government and Indian tribes, as specified by Executive
Order 13175 (59 FR 22951, November 9, 2000). This action also does not
have Federalism implications because it does 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 (64 FR 43255, August 10, 1999). This action
merely proposes to approve a state rule implementing a Federal
standard, and does not alter the relationship or the distribution of
power and responsibilities established in the Clean Air Act. This
proposed rule also is not subject to Executive Order 13045 ``Protection
of Children from Environmental Health Risks and Safety Risks''
(62 FR 19885, April 23, 1997), because it is not economically significant.
In reviewing SIP submissions, EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act. In
this context, in the absence of a prior existing requirement for the
State to use voluntary consensus standards (VCS), EPA has no authority
to disapprove a SIP submission for failure to use VCS. It would thus be
inconsistent with applicable law for EPA, when it reviews a SIP
submission, to use VCS in place of a SIP submission that otherwise
satisfies the provisions of the Clean Air Act. Thus, the requirements
of section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (15 U.S.C. 272 note) do not apply. This proposed rule does
not impose an information collection burden under the provisions of the
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
