40 CFR Part 52

[EPA-R02-OAR-2025-0290; FRL-12965-01-R2]


Approval of Source-Specific Air Quality Implementation Plan; New 
York; Calpine JFK Energy Center

AGENCY: Environmental Protection Agency.

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
determine a revision to the State of New York's State Implementation 
Plan (SIP) for the ozone National Ambient Air Quality Standard (NAAQS) 
related to a Source-specific SIP (SSSIP) revision for Calpine JFK 
Energy Center, located at Kennedy International Airport, Building 49, 
Jamaica, NY 11430 (the Facility) is approvable. The EPA is proposing to 
find that the control options in this SSSIP revision implement 
Reasonably Available Control Technology (RACT) with respect to 
NOX emissions from the relevant Facility sources, which are 
identified as six mid-size emergency hot water boilers. This SSSIP 
revision is intended to implement NOX RACT for the relevant 
Facility sources in accordance with the requirements for implementation 
of the 2008 and 2015 ozone NAAQS. The EPA proposes to determine that 
this action will not interfere with ozone NAAQS requirements and meets 
all applicable requirements of the Clean Air Act (CAA).

I. Background

Ground Level Ozone Formation

    Ground level ozone is predominantly a secondary air pollutant 
created by chemical reactions that occur when ozone precursors, 
including nitrogen oxides (NOX) and volatile organic 
compounds (VOC), chemically react in the presence of sunlight. 
Emissions from industrial facilities are anthropogenic sources of ozone 
precursors. The potential for ground-level ozone formation tends to be 
highest during months with warmer temperatures and stagnant air masses. 
Ozone levels are thus generally higher during the summer months, which 
is often referred to as ``the ozone season.'' In New York, the ozone 
season is generally considered to be between April 15 and October 15, 
while the non-ozone season is generally considered to be between 
October 16 and April 14.

Ozone Nonattainment

    A geographic area of the United States that is not meeting the 
primary or secondary National Ambient Air Quality Standard (NAAQS) for 
ozone is described as a nonattainment area.\1\ Nonattainment areas are 
classified as either Marginal, Moderate, Serious, Severe, or Extreme. 
With respect to this proposed action, there are two relevant ozone 
NAAQS standards. First, on March 12, 2008, the EPA promulgated a 
revision to the ozone NAAQS, setting both the primary and secondary 
standards at 0.075 parts per million (ppm) averaged over an 8-hour time 
frame (2008 8-hour Ozone Standard). See 73 FR 16436 (March 27, 2008). 
Second, on October 1, 2015, the EPA lowered these standards to 0.070 
ppm averaged over an 8-hour time frame (2015 8-hour Ozone Standard). 
See 80 FR 65292 (October 26, 2015). Under CAA section 184, the State of 
New York is located within the Ozone Transport Region (OTR), which 
means that it is subject to statewide RACT requirements. This Facility 
is also located in the New York-N. New Jersey-Long Island (NYMA) ozone 
nonattainment area for both the 2008 and 2015 ozone NAAQS and is a 
major source of NOX. Therefore, RACT is also being 
implemented for this facility for nonattainment planning purposes 
related to CAA section 182.
---------------------------------------------------------------------------

    \1\ Primary standards provide public health protection, 
including protecting the health of ``sensitive'' populations such as 
asthmatics, children, and the elderly. Secondary standards provide 
public welfare protection, including protection against decreased 
visibility and damage to animals, crops, vegetation, and buildings.
---------------------------------------------------------------------------

Federal RACT Requirements

    RACT is defined as the lowest emission limit that a source is 
capable of meeting through the application of control technology that 
is reasonably available considering technological and economic 
feasibility.\2\ CAA section 184(b)(2) sets forth the requirement to 
establish control measures to implement RACT for major sources of VOC 
located in the OTR. For major sources of NOX, CAA section 
182(f)(1) also applies, ``The plan provisions required under this 
subpart for major stationary sources of volatile organic compounds 
shall also apply to major stationary sources (as defined in section 
7602 of this title and subsections (c), (d), and (e) of this section) 
of oxides of nitrogen.'' The State of New York is located within the 
OTR, and thus the State is required to implement RACT for all major 
sources of VOC within the State.
---------------------------------------------------------------------------

    \2\ See, EPA, ``Guidance for determining acceptability of SIP 
regulations in non-attainment areas,'' memo 1976, Roger Strelow, 
https://www3.epa.gov/ttn/naaqs/aqmguide/collection/cp2/19761209_strelow_ract.pdf.
---------------------------------------------------------------------------

NYSDEC RACT Requirements

    The New York State Department of Environmental Conservation 
(NYSDEC) RACT regulations require applicable facilities to meet certain 
requirements, referred to as ``presumptive RACT requirements.'' These 
presumptive requirements generally require sources to implement 
emission limits, control efficiency requirements, specific control 
technologies, averaging plans, and/or fuel/raw material switching 
practices. In some instances, the general presumptive RACT requirements 
may not be technologically or economically feasible for a certain 
source, and the State can make a Source-specific RACT determination, 
which is submitted to the EPA as a SSSIP. The SSSIP should include the 
facility's RACT plan that demonstrates how the facility will implement 
RACT. The SSSIP will also include the applicable CAA title V operating 
permit conditions that address RACT requirements. These RACT variance 
permit conditions for the Facility will become Federally enforceable 
upon the EPA's final approval of this SSSIP.
    Under existing NYSDEC RACT regulations, facilities are required to 
assess all technologically feasible control options that meet the 
State's cost threshold. The cost threshold for NYSDEC RACT requirements 
is found under NYSDEC 2013 policy, ``DAR-20 Economic and Technical 
Analysis for Reasonably Available Control Technology (RACT).'' Under 
this policy, facilities must consider in their RACT determinations 
control technologies that remove VOC or NOX emissions up to 
a certain cost threshold, expressed in a dollar amount per ton of VOC 
or NOX removed, which includes an inflation-adjusted 
economic threshold.\3\
---------------------------------------------------------------------------

    \3\ The DAR-20 cost threshold is based on 1994 dollars. State of 
New York relies on the U.S. Department of Labor, Bureau of Labor 
Statistics inflationary calculator to adjust the RACT economic 
feasibility threshold over time for inflation. See https://www.bls.gov/data/inflation_calculator.htm.
---------------------------------------------------------------------------

II. The EPA's Evaluation of New York's Submission and RACT Analysis

    This action relates to a SSSIP revision that concerns the Calpine 
Corporation Kennedy International Airport Cogeneration (KIAC)/John F. 
Kennedy (JFK) Energy Center (the Facility)--located in the central 
terminal area of the JFK International Airport in Jamaica, NY. The 
Facility supplies electricity to the airport and the Consolidated 
Edison (Con Ed) Power Distribution Grid. The Facility also supplies 
steam to the airport's central heating and refrigeration plant. The 
sources at issue in this action are for the Facility's six mid-size 
emergency hot water boilers (the Boilers). The Boilers are used 
intermittently to supplement hot water generation at the airport when 
the combustion turbine-based cogeneration units are unavailable or 
cannot meet demand.
    The NYSDEC RACT regulations establish RACT requirements for this 
category of sources in 6 NYCRR subpart 227-2, ``Reasonably Available 
Control Technology (RACT) For Major Facilities of Oxides of Nitrogen 
(NOX),'' last approved into New York's SIP by the EPA on 
July 12, 2013. See 78 FR 41846. However, as explained above, the NYSDEC 
RACT regulations allow Source-specific RACT determinations if the 
presumptive RACT requirements are not technologically or economically 
feasible; such Source-specific determinations must be submitted to the 
EPA as a SSSIP.
    This SSSIP was submitted to EPA by NYSDEC on June 9, 2023. The EPA 
has reviewed the RACT determination in this SSSIP submittal for the 
Boilers for consistency with the CAA and EPA regulations, as 
interpreted through EPA actions and guidance. The intended effect of 
this Source-specific SIP revision is to establish an emission limit for 
the process specific control measure for the Boilers.

[[Page 51265]]

    The EPA is proposing to determine through this SSSIP action that 
the NOX RACT emission limit submitted by the State in this 
SSSIP for the Boilers is the lowest emission limit with the application 
of control technology that is reasonably available given technological 
and economic feasibility considerations. The respective NOX 
RACT emission limit is contained in the Facility's air permit, Title V 
operating permit, 2-6308-00096/00009 under conditions 56, 57, 58, 
emission unit B-OILRS issued by the State on June 28, 2022, and expires 
on June 27, 2027. EPA is proposing to approve the incorporation of 
permit conditions 56, 57, and 58 into the SIP. These conditions include 
monitoring, reporting, and recordkeeping requirements for the Boilers 
further described in the EPA RACT analysis below.
    The Facility submitted a RACT demonstration, dated January 2022, to 
the NYSDEC for the emission limit requirements, and NYSDEC reviewed and 
approved the emission limit as adequately implementing RACT for the 
source. NYSDEC then submitted the Source-specific SIP revision package 
at issue in this action for the EPA approval, and the EPA is proposing 
to determine the respective emission limit as implementing RACT for 
this source. The RACT variance emission limit for the Facility will 
become Federally enforceable upon the EPA's final approval of this 
SSSIP.

EPA RACT Analysis

    The following is a summary of the EPA's analysis of how the 
proposed NOX emission limit implements RACT for emission 
unit B-OILRS that represent the Boilers. Further detail on this 
analysis is provided in the TSD available in the docket for this 
proposed rulemaking.
    The RACT demonstration must show an alternate emission limit to 
comprise RACT and a RACT variance can be requested pursuant to 6 NYCRR 
subpart 227-2. Such a RACT variance can be approved if supported by a 
RACT demonstration and submitted to the EPA for review as a SIP 
revision.
    The Facility's RACT demonstration shows that the control of 
NOX emissions during hot water generation is the only 
NOX control technology that is technologically and 
economically feasible for this facility. Currently, the Facility does 
not limit the NOX emissions from the Boilers with any 
technologies. In its RACT demonstration, the Facility demonstrated that 
no cost-effective controls were technically feasible. The Facility 
operates the Boilers, which are intermittently used to produce 
additional hot water for JFK Airport when the combustion turbine-based 
cogeneration units are not available or cannot otherwise meet the 
airport demand. As described below, the Boilers are characterized as 
mid-size boilers under 6 NYCRR subpart 227-2. Based upon emission test 
data, these six units do not meet the presumptive emission limitations. 
In accordance with the provisions of 6 NYCRR subpart 227-2.5(c), the 
owner or operator can request a higher emission limit but must 
demonstrate that the emission limit in 6 NYCRR subpart 227-2.4 is not 
technically or economically feasible.
    As stated in permit Conditions 56, 57, and 58, the Facility must: 
monitor NOX total annual emissions monthly with a rolling 
12-month maximum, and report annually and monitor the Boilers when 
firing low sulfur distillate oil or natural gas once every five years 
with a one-hour average with a report once per batch or monitoring 
occurrence.
    The Boilers generate NOX emissions during hot water 
generation, range in size (heat input capacity) from 40 MMBtu/hr to 75 
MMBtu/hr and are capable of firing natural gas or distillate oil. Per 6 
NYCRR 200.1(cm), a ``boiler'' is defined as a device that combusts 
fossil fuel or wood and produces steam or heats water or any other heat 
transfer medium. The Boilers combust a fossil fuel (natural gas or 
distillate sulfur oil) and heat water. Per 6 NYCRR 227-2.2(b)(4), a 
``mid-size boiler'' is defined as a boiler with a maximum heat input 
capacity greater than 25 million Btu per hour and equal to or less than 
100 million Btu per hour.
    NYSDEC reviewed the RACT demonstration and determined that the 
alternate emission limit implements RACT for the Boilers. Specifically, 
NYSDEC approved the following case-by-case emission limit: (1) total 
emissions of 24 tons per year (tons/yr) of NOX from emission 
unit B-OILRS, on a rolling 12-month basis, with the total monthly 
NOX emissions for each boiler calculated on a monthly basis; 
(2) records of monthly NOX emissions shall be maintained in 
a permanently bound log or in electronic format with reporting 
requirements annually and reports due 30 days after the reporting 
period; (3) maximum NOX emission rate of 0.15 lb/MMBtu per 
hour for each of the Boilers when firing natural gas, and 0.25 lb/MMBtu 
per hour when firing distillate oil; and (4) NOX emission 
testing once every five years to verify that the actual NOX 
emissions from a particular boiler are less than the maximum limits per 
hour when firing low sulfur distillate oil or natural gas.
    We are proposing to determine that the following additional 
technically feasible control options do not need to be implemented 
because they are not cost effective: (1) fuel switching; (2) low-
NOX burners; and (3) flue gas recirculation.
    To determine what NOX control technologies could be 
economically and technologically feasible for the Boilers, the EPA 
reviewed the Reasonably Available Control Technology/Best Available 
Control Technology/Lowest Achievable Emission Rate Clearinghouse 
(RBLC),\4\ EPA's Alternative Control Techniques (ACT) and Control 
Techniques Guidelines (CTG), and the vendor quote provided by the State 
as part of the RACT evaluation. The EPA's RBLC search criteria were 
based on: permit dates from June 28, 2012 to June 28, 2022, process 
types for Commercial/Institutional-Size Boilers/Furnaces (<100 million 
BTU/H): 13.900 Other Fuels and Combinations (e.g., solid/liquid, 
liquid/gas); 13.220 Distillate Fuel Oil (ASTM #1,2, includes kerosene, 
aviation, diesel fuel); 13.310 Natural Gas (includes propane and 
liquefied petroleum gas), NOX pollutant, and All States. The 
EPA's RBLC review reveals that there are 54 facilities in the United 
States that possibly operate with similar practices as the Facility 
(such as having boilers or being an energy generating facility). The 
EPA also reviewed one vendor quote for the Boilers as contained in the 
SSSIP submission, and they appear to be technically sound. The EPA 
confirms that no cost-effective NOX control technologies 
have become available that could be implemented on the Facility's 
Boilers. For more information, refer to the TSD associated with this 
rulemaking.
---------------------------------------------------------------------------

    \4\ The RBLC contains case-specific information on the best 
available air pollution technologies that have been required to 
reduce the emission of air pollutants from stationary sources. See 
https://cfpub.epa.gov/rblc/index.cfm?action=Search.BasicSearch&lang=en.
---------------------------------------------------------------------------

    The EPA is proposing to determine that the proposed limit for the 
Boilers implements RACT because: (1) The 6 NYCRR subpart 227-2 
presumptive NOX limit for the Boilers of 0.08 lbs/MMBtu is 
not economically and technologically feasible for this source; (2) no 
additional control technologies beyond what are currently used at the 
Boilers are technically and economically feasible; (3) emission limit 
of maximum NOX emission rate of 0.15 lb/MMBtu per hour for 
each of the Boilers when firing natural gas, and 0.25 lb/MMBtu per hour 
when firing distillate oil comprises RACT for this

[[Page 51266]]

source; and (4) the SIP revision contains monitoring and reporting 
requirements.

III. Proposed Action

    The EPA is proposing to approve this current Source-specific 
revision because the limits included in the SSSIP are demonstrated to 
implement RACT for emission unit B-OILRS that represent the Boilers. 
Based on information provided by NYSDEC, a thorough RBLC review of 
similar sources and EPA's Alternative Control Techniques (ACT) and 
Control Techniques Guidelines (CTG), and an analysis of this Source-
specific SIP revision, the EPA proposes to determine the Facility's 
operation under the NYSDEC approved NOX emission limits for 
the Facility's Boilers.
    Specifically, the EPA proposes to determine the following limits 
and associated requirements as implementing RACT: the Facility must: 
(1) have a maximum total emissions of 24 tons/yr of NOX from 
the Boilers, on a rolling 12-month basis, with the total monthly 
NOX emissions for each boiler calculated on a monthly basis; 
(2) maintain records of monthly NOX emissions in a 
permanently bound log or in electronic format with reporting 
requirements annually and reports due 30 days after the reporting 
period; (3) have a maximum NOX emission rate of 0.15 lb/
MMBtu per hour for each of the Boilers when firing natural gas, and 
0.25 lb/MMBtu per hour when firing distillate oil; and (4) conduct 
NOX emission testing once every five years to verify that 
the actual NOX emissions from a particular boiler are less 
than the maximum limits per hour when firing low sulfur distillate oil 
or natural gas.

IV. Incorporation by Reference

    In this document, the EPA is proposing to include regulatory text 
that includes incorporation by reference. In accordance with 
requirements of 1 CFR 51.5, the EPA is proposing to incorporate by 
reference revisions to Facility's Title V operating permit conditions 
56, 57, 58 as described in section II. of this preamble. The EPA has 
made, and will continue to make, these materials generally available 
through https://www.regulations.gov.

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 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);
     Is not subject to Executive Order 14192 (90 FR 9065, 
February 6, 2025) because SIP actions are exempt from review under 
Executive Order 12866:
     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 subject to Executive Order 13045 (62 FR 19885, 
April 23, 1997) because it approves a state program;
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001); and
     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.
    In addition, the SIP is not approved to apply on any Indian 
reservation land or in any other area where EPA or an Indian Tribe has 
demonstrated that a Tribe has jurisdiction. In those areas of Indian 
country, the rule does not have Tribal implications and will not impose 
substantial direct costs on Tribal governments or preempt Tribal law as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
