SUPPLEMENTARY INFORMATION: On November 16, 2006, the Delaware
Department of Natural Resources and Environmental Control (DNREC)
submitted a revision to its State Implementation Plan (SIP) for
Regulation No. 1146--Electric Generating Unit Multi-Pollutant Regulation.
I. Background
Regulation No. 1146 establishes NOX, SO2 and
mercury emissions limits to achieve reductions of those pollutants from
Delaware's large EGUs of coal-fired and residual oil-fired EGUs with a
nameplate capacity rating of 25 megawatts (MW) or greater generating
capacity. Only the NOX and SO2 sections of this
regulation will be discussed in this rulemaking. The mercury sections
of this regulation will be discussed in a separate rulemaking.
Regulation No. 1146 will help Delaware attain and maintain the
national ambient air quality standards (NAAQS) for ozone and
particulate matter (PM2.5) and will assist Delaware in
achieving the emissions reductions needed to support Delaware's 8-hour
ozone reasonable further progress plan (RFP). This multi-pollutant
regulation will not replace the Federal Clean Air Interstate Rule
(CAIR) requirements and does not relieve affected sources from
participating in and complying with all CAIR cap-and-trade program
requirements.
II. Summary of SIP Revision
Regulation No. 1146 applies to coal-fired and residual oil-fired
EGUs located in Delaware with a nameplate capacity rating of 25 MW or
greater. The large EGUs subject to Regulation No. 1146 are Conective
Delmarva Generating, Inc.'s Edge Moor Generating Station Units 3, 4 and
5 located in New Castle County; the City of Dover's McKee Run
Generating Station Unit 3 located in Kent County; and NRG Energy,
Inc.'s Indian River Generating Station Units 1, 2, 3 and 4 located in
Sussex County.
Regulation No. 1146 also contains definitions; emissions
limitations for NOX and SO2; recordkeeping and
reporting; compliance plan; and annual mass emission limits for
NOX and SO2.
A. Emissions Limitations
1. NOX
Regulation No. 1146 includes short term NOX emission
rate limits and will be implemented in a phased manner. For Phase I,
May 1, 2009 through December 31, 2011, the short term NOX
emission rate limit is 0.15 lb/MMBTU of heat input on a rolling 24-hour
average basis. For Phase II, January 1, 2012 and beyond, the short term
NOX emission rate limit is 0.125 lb/MMBTU of heat input on a
rolling 24-hour average basis.
A unit subject to this regulation shall not emit annual
NOX mass emissions that exceed the values shown in Table I
on or after January 1, 2009.

2. SO2
Regulation No. 1146 includes short term SO2 emission
rate limits and will also be implemented in a phased manner. For Phase
I, May 1, 2009 through December 31, 2011, the short term SO2
emission rate limit is 0.37 lb/MMBTU of heat input on a rolling 24-hour
average basis. For Phase II, January 1, 2012 and beyond, the short term
SO2 emission rate limit is 0.26 lb/MMBTU of heat input on a
rolling 24-hour average basis.
A unit subject to this regulation shall not emit annual
SO2 mass emissions that exceed the values shown in Table II
on or after January 1, 2009.

------------------------------------------------------------------------
B. Compliance Demonstration
NOX and SO2 emissions from multiple units
subject to Regulation No. 1146 at a common facility may be averaged on
a heat input basis to demonstrate compliance.
Regulation No. 1146 requires compliance demonstration with the
emissions limitations for NOX and SO2 through the
use of EPA and DNREC approved continuous emissions monitoring systems
(CEMS). Regulation No. 1146 also requires that these CEMS must be
installed, certified, calibrated, operated, and maintained in
accordance with EPA requirements. For NOX and SO2
emissions, Regulation No. 1146 specifies that CEMS must comply with all
40 CFR part 75; including monitoring, recordkeeping, quality assurance/
quality control (QA/QC), and reporting requirements. These are the same
requirements that are necessary for compliance with EPA's CAIR program,
for which each of the units subject to this regulation are also subject.
C. Compliance Plan
Regulation No. 1146 requires a submission of a compliance plan from
the owner or operator of a unit subject to this regulation to DNREC on
or before July 1, 2007.
D. Recordkeeping and Reporting
Regulation No. 1146 requires compliance with all applicable
recordkeeping and reporting requirements of 40 CFR part 75. Owner or
operator of a unit subject to this regulation shall maintain for a
period of at least 5 years, copies of all measurements, tests, reports
and other information required by 40 CFR part 75. This information
shall be provided to DNREC upon request at anytime.
III. Proposed Action
EPA is proposing to approve the Delaware SIP revision for
Regulation No. 1146--Electric Generating Unit Multi-Pollutant
Regulation submitted on November 16, 2006 pertaining to NOX
and SO2. This regulation will result in the reduction of
NOX and SO2 emissions from the affected sources.
EPA is soliciting public comments on the issues discussed in this
document. These comments will be considered before taking final action.
IV. 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 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 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 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), nor will it 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), because it
merely proposes to approve a state rule implementing a Federal
requirement, 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 (62 FR 19885,
April 23, 1997), because it approves a state rule implementing a
Federal standard.
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. As required by section 3
of Executive Order 12988 (61 FR 4729, February 7, 1996), in issuing
this proposed rule, EPA has taken the necessary steps to eliminate
drafting errors and ambiguity, minimize potential litigation, and
provide a clear legal standard for affected conduct. EPA has complied
with Executive Order 12630 (53 FR 8859, March 15, 1988) by examining
the takings implications of the rule in accordance with the ``Attorney
General's Supplemental Guidelines for the Evaluation of Risk and
Avoidance of Unanticipated Takings'' issued under the executive order.
This proposed rule pertaining to Delaware's Electric Generating
Unit Multi-Pollutant Regulation, does not
[[Page 27789]]
impose an information collection burden under the provisions of the
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
