Approval and Promulgation of Implementation Plans North Carolina: 
Prevention of Significant Deterioration and Nonattainment New Source 
Review Rules

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing to approve revisions to the North Carolina 
State Implementation Plan (SIP) submitted by the State of North 
Carolina in three submittals dated November 30, 2005, March 16, 2007, 
and June 20, 2008. The proposed revisions modify North Carolina's 
Prevention of Significant Deterioration (PSD) and Nonattainment New 
Source Review (NNSR) permitting regulations in the SIP to address 
changes to the federal New Source Review (NSR) regulations, which were 
promulgated by EPA on December 31, 2002, and reconsidered with minor 
changes on November 7, 2003 (collectively, these two final actions are 
referred to as the ``2002 NSR Reform Rules''). In addition, the 
proposed revisions address an update to the NSR regulations promulgated 
by EPA on November 29, 2005 (``Ozone Implementation NSR update'') 
relating to the implementation of the 1997 8-hour ozone National 
Ambient Air Quality Standards (NAAQS). The proposed revisions include 
provisions for baseline emissions calculations, an actual-to-projected-
actual methodology for calculating emissions changes, options for 
plantwide applicability limits (PALs), recordkeeping and reporting 
requirements, and provisions recognizing nitrogen oxides 
(NOX) as a precursor to ozone. The June 20, 2008, SIP 
submittal also contains proposed revisions that are not related to 
EPA's 2002 NSR Reform Rules. EPA will propose action on those revisions 
in a separate Federal Register notice.

I. What action is EPA proposing today?

    On November 30, 2005, March 16, 2007, and June 20, 2008, the State 
of North Carolina, through the North Carolina Department of Environment 
and Natural Resources (DENR), submitted revisions to the North Carolina 
SIP. The SIP submittals consist of revisions to North Carolina Air 
Quality Rules, Subchapter 2D. Specifically, the November 30, 2005, 
proposed SIP revisions include changes to Regulation 15A (North 
Carolina Administrative Code) NCAC 2D .0531, ``Sources in Nonattainment 
Areas.'' The March 16, 2007, submittal includes changes to Regulation 
15A NCAC 2D .0530, ``Prevention of Significant Deterioration.'' The 
June 20, 2008, submittal consists of additional changes to Regulations 
15A NCAC 2D .0530, and .0531. DENR submitted these revisions in 
response to EPA's December 31, 2002, November 7, 2003, and November 29, 
2005, revisions to the Federal NSR program. Pursuant to section 110 of 
the Clean Air Act (``CAA'' or ``Act''), EPA is now proposing to approve 
these SIP revisions. The June 20, 2008, submittal also included 
revisions to NCAC Subchapter 2D, Section .2400, Clean Air Interstate 
Rules, which EPA is not taking action on at this time.

II. Why is EPA proposing this action?

    On December 31, 2002 (67 FR 80186), EPA published final rule 
changes to 40 Code of Federal Regulations (CFR) parts 51 and 52, 
regarding the CAA's PSD and NNSR programs. On November 7, 2003 (68 FR 
63021), EPA published a notice of final action on the reconsideration 
of the December 31, 2002, final rule changes. In that November 7, 2003, 
final action, EPA added the definition of ``replacement unit,'' and 
clarified an issue regarding PALs. The December 31, 2002, and the 
November 7, 2003, final actions are collectively referred to as the 
``2002 NSR Reform Rules.'' The purpose of this action is to propose to 
approve the SIP submittals from the State of North Carolina that 
include the provisions of EPA's 2002 NSR Reform Rules.
    The 2002 NSR Reform Rules are part of EPA's implementation of Parts 
C and D of title I of the CAA, 42 U.S.C. 7470-7515. Part C of title I 
of the CAA, 42 U.S.C. 7470-7492, is the PSD program, which applies in 
areas that meet the NAAQS--``attainment'' areas--as well as in areas 
for which there is insufficient information to determine whether the 
area meets the NAAQS--``unclassifiable'' areas. Part D of title I of 
the CAA, 42 U.S.C. 7501-7515, is the NNSR program, which applies in 
areas that are not in attainment of the NAAQS--``nonattainment'' areas. 
Collectively, the PSD and NNSR programs are referred to as the ``New 
Source Review'' or NSR programs. EPA regulations implementing these 
programs are contained in 40 CFR 51.165, 51.166, 52.21, 52.24, and part 
51, Appendix S.
    The CAA's NSR programs are preconstruction review and permitting 
programs applicable to new and modified stationary sources of air 
pollutants regulated under the CAA. The NSR programs of the CAA include 
a combination of air quality planning and air pollution control 
technology program requirements. Briefly, section 109 of the CAA, 42 
U.S.C. 7409, requires EPA to promulgate primary NAAQS to protect public 
health and secondary NAAQS to protect public welfare. Once EPA sets 
those standards, states must develop, adopt, and submit to EPA for 
approval, a SIP that contains emissions limitations and other control 
measures to attain and maintain the NAAQS. Each SIP is required to 
contain a preconstruction review program for the construction and 
modification of any stationary source of air pollution to assure that 
the NAAQS are achieved and maintained; to protect areas of clean air; 
to protect air quality related values (such as visibility) in national 
parks and other areas; to assure that appropriate emissions controls 
are applied; to maximize opportunities for economic development 
consistent with the preservation of clean air resources; and to ensure 
that any decision to increase air pollution is made only after full 
public consideration of the consequences of the decision.
    The 2002 NSR Reform Rules made changes to five areas of the NSR 
programs. In summary, the 2002 Rules: (1) Provide a new method for 
determining baseline actual emissions; (2) adopt an actual-to-
projected-actual methodology for determining whether a major 
modification has occurred; (3) allow major stationary sources to comply 
with PALs to avoid having a

[[Page 52228]]

significant emissions increase that triggers the requirements of the 
major NSR program; (4) provided a new applicability provision for 
emissions units that are designated clean units; and (5) excluded 
pollution control projects (PCPs) from the definition of ``physical 
change or change in the method of operation.'' On November 7, 2003 (68 
FR 63021), EPA published a notice of final action on its 
reconsideration of the 2002 NSR Reform Rules, which added a definition 
for ``replacement unit'' and clarified an issue regarding PALs. For 
additional information on the 2002 NSR Reform Rules, see, 67 FR 80186 
(December 31, 2002), and http://www.epa.gov/nsr.
    After the 2002 NSR Reform Rules were finalized and effective (March 
3, 2003), industry, state, and environmental petitioners challenged 
numerous aspects of the 2002 NSR Reform Rules, along with portions of 
EPA's 1980 NSR Rules (45 FR 52676, August 7, 1980). On June 24, 2005, 
the United States Court of Appeals for the District of Columbia Circuit 
(D.C. Circuit Court) issued a decision on the challenges to the 2002 
NSR Reform Rules. New York v. United States, 413 F.3d 3 (D.C. Cir. 
2005). In summary, the D.C. Circuit Court vacated portions of the rules 
pertaining to clean units and PCPs, remanded a portion of the rules 
regarding recordkeeping, e.g. 40 CFR 52.21(r)(6) and 40 CFR 
51.166(r)(6), and either upheld or did not comment on the other 
provisions included as part of the 2002 NSR Reform Rules. On June 13, 
2007 (72 FR 32526), EPA took final action to revise the 2002 NSR Reform 
Rules to remove from federal law all provisions pertaining to clean 
units and the PCP exemption that were vacated by the D.C. Circuit 
Court.
    With regard to the remanded portions of the 2002 NSR Reform Rules 
related to recordkeeping, on December 21, 2007, EPA took final action 
and established that a ``reasonable possibility'' applies where source 
emissions equal or exceed 50 percent of the CAA NSR significance levels 
for any pollutant (72 FR 72607). The ``reasonable possibility'' 
provision identifies for sources and reviewing authorities the 
circumstances under which a major stationary source undergoing a 
modification that does not trigger major NSR must keep records.
    Also relevant to DENR's submittals, on November 29, 2005 (70 FR 
71612), EPA promulgated implementation provisions for the 1997 8-Hour 
Ozone NAAQS--Phase 2, which made changes to the NSR regulations. These 
included, among other requirements, a requirement that emissions of 
NOX be considered ozone precursors. States were required to 
submit SIP revisions incorporating these changes by no later than June 
15, 2007.
    The 2002 NSR Reform Rules require that state agencies adopt and 
submit revisions to their SIP permitting programs implementing the 
minimum program elements of the 2002 NSR Reform Rules no later than 
January 2, 2006. (Consistent with changes to 40 CFR 51.166(a)(6)(i), 
state agencies are now required to adopt and submit SIP revisions 
within three years after new amendments are published in the Federal 
Register.) State agencies may meet the requirements of 40 CFR part 51 
and the 2002 NSR Reform Rules with different but equivalent 
regulations.
    On November 30, 2005, March 16, 2007, and June 20, 2008, the North 
Carolina DENR submitted revisions to EPA for the purpose of revising 
the State's NSR permitting provisions to adopt EPA's NSR Reform Rules 
and the Ozone Implementation NSR update. EPA is proposing to approve 
these submittals pursuant to section 110 of the CAA.

III. What is EPA's analysis of North Carolina's NSR rule revisions?

    North Carolina currently has a SIP-approved NSR program for new and 
modified stationary sources. EPA is now proposing to approve revisions 
to North Carolina's existing NSR program. North Carolina's SIP 
submittals consist of a compilation of amendments to State rules that 
became State-effective between May 1, 2005, and May 1, 2008. Copies of 
North Carolina's revised NSR rules, as well as the State's Technical 
Support Document, can be obtained from the Docket, as discussed in the 
ADDRESSES section above. A discussion of the specific changes to North 
Carolina's rules comprising the proposed SIP revisions follows.
    North Carolina Regulation 15A NCAC 2D .0530, ``Prevention of 
Significant Deterioration,'' contains the preconstruction review 
program that provides for the prevention of significant deterioration 
of ambient air quality as required under Part C of title I of the CAA 
(the PSD program). The PSD program applies to sources that are major 
stationary sources or undergoing major modifications in areas that are 
designated as attainment or unclassifiable with regard to any NAAQS. 
North Carolina's PSD program was originally approved into the SIP by 
EPA on February 23, 1982, and has been revised several times since then 
in order to remain consistent with federal rule changes.
    North Carolina's permitting requirements for major sources in or 
impacting upon nonattainment areas are set forth at Regulation 15A NCAC 
2D .0531, ``Sources in Nonattainment Areas'' (NNSR program). The North 
Carolina NNSR program was originally approved into the North Carolina 
SIP on July 26, 1982, and has been revised several times since then in 
order to remain consistent with federal rule changes. The NNSR 
requirements apply to the construction and modification of any major 
stationary source of air pollution in a nonattainment area, as required 
by Part D of title I of the CAA. To receive approval to construct, a 
source that is subject to these requirements must show that it will not 
cause a net increase in pollution, will not create a delay in meeting 
the NAAQS, and that the source will install and use control technology 
that achieves the lowest achievable emissions rate (LAER).
    The changes to North Carolina's NSR rules, which EPA is now 
proposing to approve into the North Carolina SIP, were submitted to 
update the existing North Carolina rules to meet the requirements of 
the 2002 NSR Reform Rules and the Ozone Implementation NSR update. 
These SIP revisions address baseline actual emissions, actual-to-
projected actual applicability tests, PALs, recordkeeping and reporting 
requirements, and provisions recognizing NOX as a precursor 
to ozone. North Carolina's NSR rules incorporate by reference (IBR) the 
federal NSR rules at 40 CFR 51.166 and 51.165, as amended June 13, 
2007, except for the definition of ``baseline actual emissions,'' the 
stayed equipment replacement provisions (ERP) (69 FR 40274, July 1, 
2004),\1\ the PAL adjustment provisions at 51.166(w)(10)(iv)(a) and 
51.165(f)(10)(iv)(A), the recordkeeping and reporting requirements at 
51.166(r)(6) and 51.165(a)(6), and the Ozone Implementation NSR update 
provisions at 51.165(a)(8), (a)(9) and (a)(10).
---------------------------------------------------------------------------

    \1\ EPA promulgated the ERP on October 27, 2003 (68 FR 61248). 
The ERP was challenged and the D.C. Circuit Court of Appeals stayed 
the ERP on December 24, 2003. On March 17, 2006, the Court vacated 
the ERP. See New York v. EPA, 443 F.3d 880 (D.C. Cir. 2006).
---------------------------------------------------------------------------

    EPA's evaluation of the North Carolina SIP submittals included a 
line-by-line comparison of the proposed revisions with the federal 
requirements. As a general matter, state agencies may meet the 
requirements of 40 CFR part 51, and the 2002 NSR Reform Rules, with 
different but equivalent regulations. As mentioned above, North 
Carolina chose to IBR the federal rules with several changes. The 
definition of

[[Page 52229]]

``baseline actual emissions'' at subchapter 2D .0530(b)(1) and 
.0531(a)(1) was changed to remove the provision allowing emissions 
units that are not electric utility steam generating units (EUSGUs) to 
look back 10 years to select the baseline period. North Carolina rules 
treat EUSGUs and non-EUSGUs the same by allowing a look back of only 5 
years. However, North Carolina rules provide the option of allowing a 
different time period, not to exceed 10 years, if the owner or operator 
demonstrates that it is more representative of normal source operation. 
In addition, North Carolina rules require EUSGUs to adjust downward the 
baseline emissions to account for reductions required under the North 
Carolina Clean Smokestack Act.
    With regard to the PAL adjustment provisions at 
51.166(w)(10)(iv)(a) and 51.165(f)(10)(iv)(A), the federal regulations 
provide the option that if the emissions level is equal to or greater 
than 80 percent of the PAL level, the reviewing authority may renew the 
PAL at the same level or it may set the PAL at a different level 
considering other factors per 51.166(w)(10)(iv)(b) and 51.165(f)(iv)(B) 
respectively. North Carolina rules at subchapter 2D .0530(i) and 
.0531(h) require that the PAL be renewed at the same level if emissions 
are greater than or equal to 80 percent of the PAL.
    With regard to the remanded portions of the 2002 NSR Reform Rules 
related to recordkeeping and EPA's December 21, 2007, clarifications of 
the term ``reasonable possibility'' (72 FR 72607), North Carolina did 
not incorporate by reference all the provisions at 40 CFR 51.166(r)(6) 
and 51.165(a)(6) or adopt the federal ``reasonable possibility'' 
standard. Instead, North Carolina adopted recordkeeping and reporting 
requirements that apply to all modifications that use the actual-to-
projected-actual applicability test. Therefore, the North Carolina 
provisions meet the minimum recordkeeping and reporting requirements of 
the federal rule. Pursuant to the EPA December 21, 2007, rulemaking on 
the ``reasonable possibility'' standard, North Carolina is required to 
submit a notice to EPA within 3 years to acknowledge that its 
regulations fulfill these requirements.
    With regard to the Ozone Implementation NSR update, North Carolina 
incorporated by reference all the November 29, 2005, rule revisions 
except for the provisions at 40 CFR 51.165(a)(8), (9) and (10). North 
Carolina did not IBR 40 CFR 51.165(a)(10), which addresses 
PM10 precursors in PM10 nonattainment areas, 
because there are no PM10 nonattainment areas in North 
Carolina. North Carolina did not IBR 40 CFR 51.165(a)(8) and (a)(9), 
which relate to the applicability of NOX as a precursor for 
ozone and offset ratios in nonattainment areas; however, North Carolina 
rules have equivalent requirements at subchapter 2D .0531(c) and (f). 
With respect to the offset ratios, North Carolina's rules only address 
the offset ratio for moderate nonattainment areas, which is the current 
``highest'' classification in the State. There is only one 8-hour ozone 
nonattainment area in North Carolina--the Charlotte-Gastonia-Rock Hill 
area--which is classified as moderate nonattainment. At the time that 
any area(s) in North Carolina are reclassified to any level above 
moderate during a future designation process, North Carolina rules will 
have to be revised to address the appropriate offset ratios.
    In addition to incorporating the federal rules by reference with 
several changes, North Carolina's rule revisions include two additional 
provisions that do not directly relate to the 2002 NSR Reform rules, 
including: (1) Incorporating by reference 40 CFR 52.21(r)(2) to clarify 
the period of validity of approval to construct; and (2) requiring that 
all new natural gas-fired electrical utility generating units install 
best available control technology (BACT) or LAER, as appropriate. This 
second requirement was included in the North Carolina rules for clarity 
and consistency with restrictions on use of allowances imposed by an 
agreement resulting from provisions of the North Carolina Clean 
Smokestacks Act.\2\
---------------------------------------------------------------------------

    \2\ Any allowances for emissions reductions achieved under the 
Clean Smokestacks Act are not available to the subject facilities, 
nor any other sources, and may not be used to offset emissions and 
avoid installation of BACT or LAER on new natural gas-fired units.
---------------------------------------------------------------------------

    After evaluation of the submittals and supporting documentation for 
revisions to North Carolina's NSR regulations, EPA has determined that 
the differences from the federal regulations discussed above do not 
make North Carolina's NSR program less stringent than the federal 
program. Therefore, EPA has determined that the proposed SIP revisions 
are consistent with the federal program requirements for the 
preparation, adoption and submittal of implementation plans for NSR set 
forth at 40 CFR 51.165 and 51.166, and are therefore approvable.

IV. What action is EPA taking today?

    EPA is proposing to approve the changes made to North Carolina's 
Regulations 15A NCAC 2D .0530 and .0531, as submitted by the North 
Carolina DENR on November 30, 2005, March 16, 2007, and June 20, 2008, 
as revisions to the North Carolina SIP.

V. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
proposed action merely approves state law as meeting Federal 
requirements and does not impose additional requirements beyond those 
imposed by state law. For that reason, this proposed action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     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);
     Does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA; and
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the state, and EPA notes that

[[Page 52230]]

it will not impose substantial direct costs on tribal governments or 
preempt tribal law.
