Approval and Promulgation of Air Quality Implementation Plans; 
Maryland; NOX and SO2 Emissions Limitations for Fifteen Coal-Fired 
Electric Generating Units

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a State Implementation Plan (SIP) 
revision submitted by the Maryland Department of the Environment (MDE). 
This revision pertains to regulations for emission limitations at 15 
Maryland power plants. The State requested that regulations 
establishing statewide tonnage caps for emissions of NOX and 
SO2 from 15 coal-fired electric generating units in Maryland 
be approved. These regulations also establish monitoring and reporting 
requirements, and authorize the MDE to reduce or waive penalties for 
non-compliance under certain conditions and provide for judicial review 
of decisions by the MDE to grant a reduction or waiver of penalties. 
This action is being taken under the Clean Air Act (CAA).

DATES: Written comments must be received on or before February 11, 
2008.

SUPPLEMENTARY INFORMATION: On July 12, 2007, the Maryland Department of 
the Environment (MDE) submitted a revision to its State Implementation 
Plan (SIP) for approval of emission limitations and related 
requirements for nitrogen oxides (NOX) and sulfur dioxide 
(SO2) at 15 coal-fired electric generating units in 
Maryland.

I. Background

    On April 6, 2006, Maryland signed into law the Healthy Air Act (Ch. 
23, Acts of 2006), which requires MDE to adopt certain regulations. One 
such requirement under the Act is to establish caps on the amount of 
NOX and SO2 emissions that certain affected 
facilities can emit. These proposed regulations are more stringent than 
the Clean Air Interstate Rule (CAIR), which was published by EPA on May 
12, 2005 (70 FR 25162).
    In the CAIR rule, EPA determined that 28 States and the District of 
Columbia contribute significantly to nonattainment and interfere with 
maintenance of the NAAQS for fine particles (PM2.5) and/or 
8-hour ozone in downwind States in the eastern part of the country. As 
a result, EPA required those upwind States to revise their State 
Implementation Plans (SIPs) to include control measures that reduce 
emissions of SO2, which is a precursor to PM2.5 
formation, and/or NOX, which is a precursor to both ozone 
and PM2.5 formation. Under CAIR, States may implement these 
reduction requirements by participating in the EPA-administered cap-
and-trade programs or by adopting any other control measures.
    Maryland's proposed regulations are more restrictive than the CAIR 
rules in that they establish specific emission limitations for certain 
Maryland sources and, unlike the CAIR rules, do not permit surrender of 
allowances to achieve compliance. While these regulations modify some 
of the flexibility of CAIR by requiring the installation of on-site 
pollution controls at the 15 Maryland power plants, they ensure that 
appropriate local emissions reductions will occur where they are needed 
in order to attain the NAAQS by 2010.

II. Summary of SIP Revision

    The MDE is requesting that regulations (under COMAR 26.11.27) 
establishing tonnage caps for emissions of NOX and SO2 
from 15 coal-fired electric generating units (EGUs) in Maryland be 
approved. The purpose of these regulations is to help bring Maryland 
into attainment with the NAAQS for ozone and fine particulate matter by 
the 2010 attainment deadline. The 15 affected units are as follows:

------------------------------------------------------------------------
         Electric generating unit                   Jurisdiction

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

III. Proposed Action

    Maryland has met the requirements for submitting a SIP revision for 
limiting NOX and SO2 emissions from certain 
Maryland power plants. EPA is proposing to approve the Maryland SIP 
revision for limiting NOX and SO2 emissions at 15 
coal-fired EGUs, which was submitted on July 12, 2007. 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 (65 
FR 67249, 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 CAA. 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 CAA. 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

[[Page 1853]]

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 CAA. 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 action proposing approval of Maryland's SIP revision concerning 
emission limitations for NOX and SO2 at 15 coal-
fired EGUs does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501, et 
seq.).
