40 CFR Part 52

[EPA-R03-OAR-2016-0783; FRL-9961-03-Region 3]


Approval and Promulgation of Air Quality Implementation Plans; 
Maryland; Regional Haze Best Available Retrofit Technology Measure for 
Verso Luke Paper Mill

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve a state implementation plan (SIP) revision submitted by the 
State of Maryland. This revision pertains to a best available retrofit 
technology (BART) alternative measure for the Verso Luke Paper Mill 
(the Mill) submitted by the State of Maryland. Maryland requests new 
emissions limits for sulfur dioxide (SO2) and nitrogen 
oxides (NOX) for power boiler 24 at the Mill and a 
SO2 cap on tons emitted per year for power boiler 25, while 
also requesting removal of the specific BART emission limits for 
SO2 and NOX from power boiler 25. The alternative 
BART measure will provide greater reasonable progress for 
SO2 and NOX for regional haze by resulting in 
additional emission reductions of 2,055 tons per year (tpy) of 
SO2 and an additional 804 tpy of NOX than would 
occur through the previously approved BART measure for power boiler 25, 
a BART subject source. This action is being taken under the Clean Air 
Act (CAA).

SUPPLEMENTARY INFORMATION:

I. Background

    Regional haze is impairment of visual range or colorization caused 
by air pollution, principally by fine particulate matter 
(PM2.5), produced by numerous sources and activities, 
located across a broad regional area. The sources include, but are not 
limited to, major and minor stationary sources, mobile sources, and 
area sources including non-anthropogenic sources. These sources and 
activities may emit PM2.5 (e.g., sulfates, nitrates, organic 
carbon, elemental carbon, and soil dust), and their precursors (e.g., 
SO2, NOX, and in some cases, ammonia and volatile 
organic compounds). Fine particulate matter can also cause serious 
health effects and mortality in humans, and contributes to 
environmental effects such as acid deposition and eutrophication.
    In the CAA Amendments of 1977, Congress established a program to 
protect and improve visibility in the Nation's national parks and 
wilderness areas. See CAA section 169A. Congress amended the visibility 
provisions in the CAA in 1990 to focus attention on the problem of 
regional haze. See CAA section 169B. EPA promulgated regional haze 
regulations (RHR) in 1999 to implement sections 169A and 169B of the 
CAA. These regulations require states to develop and implement plans to 
ensure reasonable progress towards improving visibility in mandatory 
Class I Federal areas.\1\ See 64 FR 35714 (July 1, 1999); see also 70 
FR 39104 (July 6, 2005) and 71 FR 60612 (October 13, 2006).
---------------------------------------------------------------------------

    \1\ While Maryland has no Class I areas within its borders, 
there are several Class I areas nearby including Dolly Sods 
Wilderness Area and Otter Creek Wilderness Area in West Virginia; 
Brigantine Wilderness in New Jersey; Great Smoky Mountains National 
Park in North Carolina and Tennessee; James River Face and 
Shenandoah National Park in Virginia; Linville Gorge in North 
Carolina; and Mammoth Cave National Park in Kentucky.
---------------------------------------------------------------------------

    The RHR requires each state's regional haze implementation plan to 
contain emission limitations representing best available retrofit 
technology (BART) and schedules for compliance with BART for each 
source subject to BART, unless the state demonstrates that an emissions 
trading program or other alternative measure will achieve greater 
reasonable progress toward natural visibility conditions. The 
requirements for alternative measures are established at 40 CFR 
51.308(e)(2).
    In addition to demonstrating greater reasonable progress towards 
improving visibility, among other things, the RHR also requires that 
all necessary emission reductions from a BART alternative take place 
during the period of the first long-term strategy for regional haze 
(i.e., 2008-2018) and requires a demonstration that the emission 
reductions from the alternative measure will be surplus to the 
reductions from measures adopted to meet CAA requirements as of the 
baseline date of the SIP. 40 CFR 51.308(e)(2). The baseline date for 
regional haze SIPs is 2002. See Memorandum from Lydia Wegman and Peter 
Tsirigotis, 2002 Base Year Emission Inventory SIP Planning: 8-hr Ozone, 
PM2.5, and Regional Haze Programs, November 8, 2002. http://www.epa.gov/ttn/oarpg/t1/memoranda/2002bye-gm.pdf. See 79 FR 56322, 
56328-29 (September 19, 2014) (proposing approval of alternative BART 
for Arizona SIP).
    Maryland's regional haze SIP was submitted by the Maryland 
Department of the Environment (MDE) on February 13, 2012 and approved 
by EPA in June 2012. See 77 FR 39938 (June 13, 2012). This regional 
haze SIP included, among other measures, BART emission limits for power 
boiler 25 at the Verso Luke Paper Mill because power boiler 25 was a 
BART subject source. The BART emission limits which EPA had approved in 
June 2012 for power boiler 25 were 0.44 pounds per million British 
thermal units (lb/MMBtu) for SO2, a 30-day rolling limit of 
0.40 lb/MMBtu for NOX, and 0.07 lb/MMBtu for particulate 
matter (PM).\2\
---------------------------------------------------------------------------

    \2\ While EPA's approval of Maryland's regional haze SIP in 2012 
included a PM limit for power boiler 25 of 0.07 lb/MMBtu, Maryland 
is not seeking to revise that PM limit for BART on power boiler 25 
and thus the PM limit of 0.07 lb/MMBtu remains on power boiler 25. 
See 77 FR 39938. This rulemaking action pertains to adjusting the 
BART limits for SO2 and NOX for power boiler 
25.
---------------------------------------------------------------------------

II. Summary of SIP Revision and EPA's Analysis

    On November 28, 2016, the State of Maryland through the MDE 
submitted to EPA a revision to the Maryland regional haze SIP 
consisting of a BART alternative measure for Verso Luke Paper Mill. The 
SIP revision seeks to revise the BART strategy for the Verso Luke Paper 
Mill, including specifically the emission limits for power boiler 25 
for SO2 and NOX.
    MDE states that Verso Luke Paper Mill is eliminating the use of 
coal as a source of fuel used in power boiler 24 and replacing it with 
natural gas. MDE's SIP revision submittal seeks alternative BART 
emission limits for SO2 and NOX for power boiler 
24, and seeks to remove the previously approved BART requirements for 
SO2 and NOX from power boiler 25 and replace them 
with new, alternative emission requirements. Specifically, for power 
boiler 24 at the Mill, Maryland's SIP revision seeks to establish (1) a 
new BART emission limit of 0.28 lb/MMBtu, measured as an hourly average 
for SO2; (2) a new BART emission limit of 0.4 lb/MMBtu, 
measured on a 30-day rolling average for NOX; and (3) 
associated monitoring, recordkeeping and reporting requirements. For 
power boiler 25, this SIP revision seeks to: (1) Remove the 
SO2 BART emission limit approved by EPA in June 2012 and 
seeks to establish an annual SO2 cap of 9,876 tons measured 
on a 12-month rolling average; (2) remove the NOX BART 
emission limit but retain existing requirements under COMAR 26.11.14.07 
applicable to the power boiler; and (3) impose associated monitoring, 
recordkeeping, and reporting requirements. The BART requirements for PM 
approved by EPA in June 2012 on power boiler 25 would remain unchanged 
on power boiler 25.
    MDE's analysis demonstrates that the alternative SO2 
BART measure (i.e. new SO2 emission limit on power boiler 
24; removal of approved SO2 BART limit and new annual 
SO2 cap on power boiler 25) would provide an additional 
2,055 tpy in SO2 emissions reductions (or 20% more emission 
reductions) than the tons per year to be reduced by the currently 
approved BART requirements on power boiler 25. MDE's analysis also 
shows that the alternative NOX BART measure on power boiler 
24 (with removed BART limit on power boiler 25) would provide an 
additional 804 tpy in NOX emission reductions than the 
currently approved BART requirements on power boiler 25. Finally, MDE's 
analysis shows that the alternative NOX BART measure on 
power boiler 24 would provide a 227 tons per ozone season 
NOX benefit than would the currently approved BART 
requirements on power boiler 25.
    Thus, with the additional SO2 and NOX 
emission reductions per year, EPA finds that the alternative 
SO2 and NOX BART emission limits on power boiler 
24 (with the SO2 tpy cap on power boiler 25) will provide 
for greater reasonable progress toward achieving natural visibility 
conditions than would be achieved through the currently approved BART 
emission limits on power boiler 25. EPA also finds the emission 
reductions from the new limits on power boiler 24 (and SO2 
tpy cap on power boiler 25) have been implemented before the end of the 
first regional haze planning period (i.e., 2018). In addition, the 
emission reductions from the proposed BART emission limits for power 
boiler 24 for

[[Page 24616]]

SO2 and NOX are surplus to reductions resulting 
from CAA requirements as of the baseline date of the SIP or 2002. More 
information on Maryland's SIP submittal and on EPA's analysis of 
emission reductions from the alternative BART measure (including 
discussion of the reductions as implemented and surplus) is provided in 
the Technical Support Document (TSD) which is available online at 
www.regulations.gov for this rulemaking. Therefore, EPA finds 
Maryland's SIP revision for the alternative BART emission limits for 
SO2 and NOX for power boiler 24 (and 
SO2 cap on power boiler 25) meet the requirements for an 
alternative BART measure in accordance with CAA section 169A and as 
established at 40 CFR 51.308(e)(2) in the RHR.
    In addition, EPA finds that this SIP revision, which seeks to 
remove BART SO2 and NOX emission limits for power 
boiler 25 from the approved Maryland regional haze SIP, meets the 
requirements of CAA section 110(l) and will not interfere with 
attainment and maintenance of any NAAQS, reasonable further progress or 
any other applicable CAA requirement. EPA finds that Maryland has 
demonstrated that additional SO2 and NOX emission 
reductions will be achieved each year with the alternative BART 
emission limits on power boiler 24 and SO2 tpy cap on power 
boiler 25, and as such, no interference with reasonable further 
progress or any NAAQS is expected. As discussed previously, the 
alternative BART emission limits on power boiler 24 meet other CAA 
requirements in section 169A and 40 CFR 51.308(e)(2). More information 
on Maryland's SIP submittal and demonstration of greater reasonable 
progress from the alternative BART measure is provided in the TSD under 
Docket ID No. EPA-R03-OAR-2016-0783 which is available online at 
www.regulations.gov for this rulemaking. EPA is soliciting public 
comments on the issues discussed in this document. These comments will 
be considered before taking final action.

III. Proposed Action

    EPA has reviewed Maryland's SIP revision seeking an alternative 
BART measure and emission limits for power boiler 24 (and 
SO2 tpy cap on power boiler 25) compared to EPA's previously 
federally enforceable BART limits for SO2 and NOX 
on power boiler 25. EPA finds that the alternative BART measure for 
Verso Luke Paper Mill with SO2 and NOX limits as 
alternative BART on power boiler 24 will result in greater emission 
reductions in SO2 and NOX from the facility and 
provide greater reasonable progress and greater visibility improvement 
than the currently approved BART measure which applies solely to power 
boiler 25. Specifically, the conversion of power boiler 24 from a coal-
burning boiler to a natural gas power boiler with new emission limits 
contained within a federally enforceable permit is expected to result 
in fewer SO2 and NOX emissions from the Mill. 
MDE's analysis shows that in comparison to the currently approved BART 
requirements on power boiler 25, the alternative BART measure on power 
boiler 24 of 0.28 lb/MMBtu, measured as an hourly average for 
SO2 and 0.4 lb/MMBtu, measured on a 30-day rolling average 
for NOX with the 9,876 SO2 cap on power boiler 
25, would provide (1) an additional 2,055 tpy in SO2 
emissions reductions; (2) an additional 804 tpy in NOX 
emission reductions; and (3) a 227 tons per ozone season NOX 
benefit. In addition, EPA finds that the alternative BART emission 
limits will result in reductions surplus to CAA requirements as of 2002 
and will be implemented prior to the end of 2018. EPA proposes to 
approve the November 28, 2016 SIP submittal as it meets the 
requirements in CAA section 169A and in 40 CFR 51.308(e)(2). EPA also 
proposes to incorporate by reference the permit requirements for power 
boilers 24 and 25 issued August 17, 2016 for the Mill, which include 
alternative emission requirements, as well as monitoring, recordkeeping 
and reporting requirements.
    EPA also finds that this SIP revision meets the requirements of CAA 
section 110(l) and will not interfere with attainment and maintenance 
of any NAAQS, reasonable further progress or any other applicable CAA 
requirement. Therefore, EPA proposes to approve Maryland's November 28, 
2016 SIP revision submittal as it meets CAA requirements.

IV. Incorporation by Reference

    In this proposed rule, EPA is proposing to include in a final EPA 
rule regulatory text that includes incorporation by reference. In 
accordance with requirements of 1 CFR 51.5, EPA is proposing to 
incorporate by reference the permit requirements for power boilers 24 
and 25 issued August 17, 2016 for Verso Luke Paper Mill, which include 
alternative emission requirements, as well as monitoring, recordkeeping 
and reporting requirements for power boilers 24 and 25 as discussed in 
section II of this notice of proposed rulemaking and the TSD. EPA has 
made, and will continue to make, these materials generally available 
through http://www.regulations.gov and/or at the EPA Region III Office 
(please contact the person identified in the FOR FURTHER INFORMATION 
CONTACT section of this preamble for more information).

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 CAA 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 
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 Orders 
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 
2011);
     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 proposed rule, pertaining to alternative BART 
emission limits for Verso Luke Paper Mill, does

[[Page 24617]]

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