SUPPLEMENTARY INFORMATION:

Background

    The General Provisions of the NSPS in 40 Code of Federal
Regulations (CFR) part 60 and the General Provisions of the NESHAP in
40 CFR part 61 provide that a source owner or operator may request a
determination of whether certain intended actions constitute the
commencement of construction,

reconstruction, or modification. EPA's written responses to these
inquiries are commonly referred to as applicability determinations. See
40 CFR 60.5 and 61.06. Although the NESHAP part 63 regulations [which
include Maximum Achievable Control Technology (MACT) standards and/or
Generally Available Control Technology (GACT) standards] and Section
111(d) of the Clean Air Act (CAA) contain no specific regulatory
provision providing that sources may request applicability
determinations, EPA also responds to written inquiries regarding
applicability for the part 63 and Section 111(d) programs. The NSPS and
NESHAP also allow sources to seek permission to use monitoring or
recordkeeping that is different from the promulgated requirements. See
40 CFR 60.13(i), 61.14(g), 63.8(b)(1), 63.8(f), and 63.10(f). EPA's
written responses to these inquiries are commonly referred to as
alternative monitoring decisions. Furthermore, EPA responds to written
inquiries about the broad range of NSPS and NESHAP regulatory
requirements as they pertain to a whole source category. These
inquiries may pertain, for example, to the type of sources to which the
regulation applies, or to the testing, monitoring, recordkeeping, or
reporting requirements contained in the regulation. EPA's written
responses to these inquiries are commonly referred to as regulatory
interpretations.
    EPA currently compiles EPA-issued NSPS and NESHAP applicability
determinations, alternative monitoring decisions, and regulatory
interpretations, and posts them to the ADI on a regular basis. In
addition, the ADI contains EPA-issued responses to requests pursuant to
the stratospheric ozone regulations, contained in 40 CFR part 82. The
ADI is a data system on the Internet with over three thousand EPA
letters and memoranda pertaining to the applicability, monitoring,
recordkeeping, and reporting requirements of the NSPS, NESHAP, and
stratospheric ozone regulations. Users can search for letters and
memoranda by date, office of issuance, subpart, citation, control
number, or by string word searches.
    Today's notice comprises a summary of 66 such documents added to
the ADI on March 22, 2016. This notice lists the subject and header of
each letter and memorandum, as well as a brief abstract of the letter
or memorandum. Complete copies of these documents may be obtained from
the ADI on the Internet through the Resources and Guidance Documents
for Compliance Assistance page of the Clean Air Act Compliance
Monitoring Web site under ``Air'' at: https://www2.epa.gov/compliance/resources-and-guidance-documents-compliance-assistance.

Summary of Headers and Abstracts

    The following table identifies the control number for each document
posted on the ADI data system on March 22, 2016; the applicable
category; the section(s) and/or subpart(s) of 40 CFR part 60, 61, or 63
(as applicable) addressed in the document; and the title of the
document, which provides a brief description of the subject matter.
    We have also included an abstract of each document identified with
its control number after the table. These abstracts are provided solely
to alert the public to possible items of interest and are not intended
as substitutes for the full text of the documents. This notice does not
change the status of any document with respect to whether it is ``of
nationwide scope or effect'' for purposes of CAA section 307(b)(1) For
example, this notice does not convert an applicability determination
for a particular source into a nationwide rule. Neither does it purport
to make a previously non-binding document binding.

Abstract for [1500021]

    Q: Will EPA approve a change to the previously approved March 22,
2011 alternative monitoring plan (AMP) for Shell Oil Products Puget
Sound Refinery (PSR) in Anacortes, Washington?
    A: Yes. EPA conditionally approves Shell's revision to the PSR 2011
AMP. For the monitoring of H2S, PSR is requesting to monitor as
required by NSPS subpart J, rather than the alternative monitoring
method that was specified in the 2011 AMP. PSR requests that certain
portions of the approved AMP stay in place to maintain approval of an
alternative means for demonstrating compliance for three interconnected
flares. The conditions that must be satisfied to allow PSR to rely on
the AMP instead of utilizing an H2S continuous monitoring system
according to subpart J are stated in the EPA approval letter.

    Q: Will EPA approve an alternative monitoring plan (AMP) for the
Shell Oil Anacortes, Washington facility to install, maintain, and
operate a total sulfur continuous monitoring system (CMS) as an
alternative to a hydrogen sulfide (H2S) CMS, and to use sulfur data
collected at the east flare to represent the sulfur content at the
north and south flares?
    A: Yes. EPA conditionally approves Shell's AMP for utilizing a H2S
CMS. The conditions to allow Shell to rely on the AMP instead of
utilizing an H2S CMS are stated in the EPA is approval letter.

Abstract for [1500023]

    Q: Will EPA grant approval of exempted status under 40 CFR
60.2887(h) of the NSPS subpart EEEE as a rural institutional waste
incinerator for an incineration unit that Glacier Bay National Park and
Preserve (the Park) in Alaska intends to purchase and install?
    A: Yes. EPA determines that the proposed incinerator meets the
exclusion for rural institutional waste incinerators because the unit
is located more than 50 miles from the boundary of the nearest
Metropolitan Statistical Area, alternative disposal options are not
available or are economically infeasible, and the Park has submitted
this request prior to initial startup of the incinerator.

Abstract for [1500024]

    Q: Are all on-site units at Kalama Export located in Kalama,
Washington that were constructed after August 3, 1978, subject to NSPS
subpart DD for Grain Elevators when applicability is triggered due to
expanded capacity?
    A: No. In its response to the Southwest Clean Air Agency in
Vancouver, Washington, EPA explains that the rule applies to each
individual affected facility at a grain elevator. Therefore, only the
units that are constructed, modified, or reconstructed when and after
the NSPS is triggered because of expanded capacity become subject to
the rule.

Abstract for [1500025]

    Q1: Does NSPS subpart AAAA for Small Municipal Waste Combustion
(MWC) Units apply to gas combustion turbine that combust a small amount
of non-condensable hydrocarbon gases, which is located at the Green
Power facility in Pasco, Washington?
    A1: Yes. In a response to the Washington State Department of
Ecology and the counsel to the source, EPA indicates that the NSPS
subpart AAAA applies to the gas combustion turbine it is considered to
be within the MWC unit boundaries and based on the capacity of the MWC.
Based on the MWC definition at 40 CFR 60.1465, the catalytic pressure-
less de-polymerization process (CDP) begins the MWC since it is used to
convert municipal solid waste into synthetic liquid petroleum fuel,
which includes a small amount of non-condensable hydrocarbon gases.
Since the non-condensable hydrocarbon gas generated by the CDP is
combusted in the turbine, the compressor section and combustor section
of the turbine at the facility are within the MWC boundaries. In
addition, it is determine that the combustion capacity of the MWC,
which would not include the capacity attributable to the flare since it
is a control device, is within the applicable range of subpart AAAA.
Furthermore, the Green Power operation does not combust landfill gases
and the landfill gas exemption, therefore, is not applicable.
    Q2: Does NSPS subpart AAAA apply to the Green Power CDP if it
operates in anaerobic environment, exposed only to inert gases, due to
explosion hazard?
    A2: No. EPA determines that the Green Power CDP would not be
subject to Subpart AAAA due to the absence of combustion if the plant
is constructed such that there is no combustion of the synthetic fuel
product.
    Q3: Does NSPS subpart AAAA apply to the Green Power proposed Algae
Production Alternative whereby the non-condensable hydrocarbon gases
produced in the reactor are routed to a biological treatment unit as a
nutrient in the production of algae which would subsequently be
harvested and reintroduced as a feedstock for the CDP process?
    A3: No. EPA determines that in this scenario Subpart AAAA would not
apply due to the absence of combustion.

    Q: Will EPA approve a source test plan submitted by Eielson Air
Force Base in Alaska for a particulate matter source test on six bin
vent filters for a new mechanical coal tipper subject to NSPS subpart
Y?
    A: Yes. EPA approves the Eielson source test plan under subpart Y.
Eielson has incorporated the guidance received by EPA regarding the
proper location for a testing port installation to address issues with
inadequate duct diameter sizing for that bin into the source test plan.

Abstract for [1500027]

    Q1: Will EPA, in consideration of difficulty in applying existing
methods to new technology, waive the Method 5 and a portion of the
Method 9 readings for three ship loader bustle filters at EGT
Development, LLC's (EGT's) Export Elevator facility at Port of
Longview, Washington?
    A1: Yes. EPA grants EGT the waiver for the Method 5 reading
required under the initial performance and for a portion of the
required Method 9 readings for the three bustle filters for several
reasons. There are technical difficulties that arise in performing the
test methods with the new loading spout dust control system design.
Specifically, technical issues arise with conducting the Method 5 test
where the loading spout dust control system has been moved to the
bottom of the ship loader spout, and with conducting a Method 9 opacity
reading while the loading spout is within the hold of the ship loading
grain. These technical issues combined with the anticipated significant
margin of compliance, the testing of other units with identical filter
media at the same facility, and the opacity readings that can be
performed justifies the waiver approval.
    Q2: Will EPA approve a waiver of initial performance testing for
certain Donaldson bin vent CPV design PowerCore Filters (CPV filters)
that EGT plans to install at this facility when they are in a group of
identical units?
    A2: Yes. EPA waives the initial Method 5 performance test for
certain CPV filters as outlined in the EPA approval letter. NSPS
emission test results with Duraplex filter media show maximum emissions
are an order of magnitude lower than the

manufacturer's guarantee (0.002 grains/dscf), and two orders of
magnitude lower than the 0.01 grains/dscf NSPS limit. Furthermore, the
local air permitting authority will be requiring additional testing on
a reasonable schedule and there will be a rotation of testing within a
group, so that a different unit within the group is tested each time
for any future performance tests. This applies to a total of 14 NSPS
test units, which represents a group of identical units where that
group is unique, has a unique air volume and aspirates a conveyor or
facility with a unique conveying capacity.

    Q: Will EPA waive the requirement for Cargill Environmental Finance
(Cargill) to performance test at two biogas-fueled generators under
NSPS subpart JJJJ based on the test results of an identical (third)
biogas-fueled generator at the Dry Creek Dairy in Hanson, Idaho?
    A: Yes. EPA waives the Cargill performance test for the three
generators that are located at the same facility, produced by the same
manufacture, have the same model number, rated capacity, operating
specifications, and are maintained in a similar manner. There is a
substantial margin of compliance documented by the prior performance
test results that were submitted.

Abstract for [1500029]

    Q: Will EPA waive the requirement of 40 CFR 60.8(d) to provide
notification 30 days in advance of a performance test for recently
installed biogas-fueled generators at Big Sky West in Gooding, Idaho
due to winter weather conditions and the pending holidays?
    A: Yes. EPA waives the requirement to provide notification 30 days
in advance of a performance test pursuant to the provisions at 40 CFR
60.19(f)(3) to implement it early in December due to weather conditions
and the pending Holidays. EPA requests that you provide the exact
testing date, a copy of the full testing protocol, and the results of
the test once completed to the regulatory agencies.

Abstract for [1500030]

    Q: Does EPA determine that Shell Offshore's incineration unit
located on the Discoverer Drill vessel, operated in the Chukchi Sea is
exempted from the requirements of 40 CFR part 60 subpart CCCC for
Commercial and Industrial Solid Waste Incineration Units pursuant to
the exemption provided in 40 CFR 60.2020(c)(2)?
    A: Yes. Based on the information provided, EPA determines that
Shell's incinerator qualifies for the exemption in 40 CFR 60.2020(c)(2)
for units under a certain capacity that burn greater than 30 percent
municipal solid waste or refuse-derived fuel, provided that Shell keeps
the records required to demonstrate that it continues to qualify for
the exemption on an ongoing basis.

Abstract for [1500031]

    Q: Does EPA determine that physical changes made to two boilers
subject to NSPS subpart Dc owned and operated by Yakama Forest Products
(YFP) at the Large Log Complex have de-rated the boilers' heat input
capacity?
    A: Yes. Based on the test data submitted following the physical
changes of replacing the burners on each boiler, EPA determines that
boilers No. 3 and 4 have been permanently de-rated to a heat input
capacity below 30 MM BTU/hr. YFP must ensure that oil pressure at the
burners meets the conditions of this determination to remain consistent
with the conditions during the source test that was the basis for this
determination.

Abstract for [1500033]

    Q: Will EPA approve Northwest Pipeline's request for an extension
of the deadline to conduct a performance test required by 40 CFR
60.4340(a) in NSPS subpart KKKK for a turbine located at the Chehalis
Compressor Station?
    A: No. EPA determines that an applicable basis for waiving the
testing requirement has not been identified. According to 40 CFR
60.4340(a), testing can be performed once every two years when
emissions are less than 75 percent of the emission limit. Therefore,
Northwest Pipeline must perform annual performance tests in accordance
with Sec.  60.4400.

Abstract for [1500034]

    Q: Will EPA approve an alternative monitoring procedure (AMP)for
monitoring the amount of waste combusted in the Northstar incinerator
to demonstrate that the incinerator qualifies for the co-fired
combustor exemption under 40 CFR part 60 subpart Ec for Hospital
Medical Infectious Waste (HMIW) Incinerators located at BP Exploration
Alaska's (BPXA's) Northstar Development Facility in the Beaufort Sea?
    A: No. EPA denies the AMP because use of the proposed method to
weigh only the HMIW incinerated, instead of weighing both the HMIW and
the non-HMIW, will not assure compliance with BPXA's claim that the
incinerator meets the exemption for co-fired combustors under 40 CFR
part 60 subpart Ec, as well as the exemption for ``municipal waste
combustion units'' in 40 CFR 62.14525(c)(2).

Abstract for [1500035]

    Q: Does EPA determine that Andarko's incineration unit located at
various drilling locations within the Gubik and Chandler Prospects in
Alaska is exempted from the requirements of 40 CFR part 60 subpart CCCC
pursuant to the provisions at 40 CFR 60.2020(c)(2)?
    A: Yes. Based on the information provided, EPA determines that
Andarko's incinerator qualifies for the exemption in 40 CFR
60.2020(c)(2) for units under a certain capacity that burn greater than
30 percent municipal solid waste or refuse-derived fuel. Andarko must
keep the records required to demonstrate that it continues to qualify
for the exemption on an ongoing basis.

Abstract for [1500036]

    Q: Is fuel sampling required for two turbines owned by Black Hills
Corporation that monitor under NSPS subpart GG custom fuel monitoring
schedules for semi-annual periods in which the turbines have not
operated for the entire semi-annual period? The turbines are located at
the Glenns Ferry Cogeneration Partners and Rupert Cogeneration Partners
facilities in Idaho.
    A: No. EPA determines that fuel sampling required by a custom fuel
monitoring schedule is not required for semi-annual periods in which
the turbine has not operated for the entire semi-annual period.
Sampling must be done upon re-startup.

Abstract for [1500038]

    Q: Will EPA waive the requirement in 40 CFR 60.8(d) for Cargill to
provide a notification 30 days in advance of a performance test for the
recently installed biogas-fueled generators at Dry Creek Dairy in
Hansen, Idaho?
    A: Yes. EPA waives the requirement to provide notification 30 days
in advance of a performance test pursuant to the provisions at 40 CFR
60.19(f)(3). The source identified a date on which testing would be
conducted.

Abstract for [1500039]

    Q: Will EPA grant a waiver to Covanta Marion, Incorporated (CMI) in
Brooks, Oregon, for the municipal waste combustor (MWC) unit load level
limitations, under 40 CFR 60.53b(b)(2), for the two weeks preceding,
and during the annual dioxin/furan and mercury performance tests for
the purpose of evaluating system performance?

    A: Yes. For the purpose of evaluating system performance, EPA
waives the MWC load limit for the two week period preceding, and during
the annual dioxin/furan and mercury performance test.

Abstract for [1500049]

    Q: Will EPA provide a waiver pursuant to 40 CFR 60.8(b)(4) from the
initial and subsequent performance testing requirement under NSPS
subpart KKKK for three identical Solar Saturn T-1301 turbines operating
under the same conditions on the same platform in the Cook Inlet at XTO
Energy's Kenai, Alaska facility?
    A: Yes. EPA grants the request to expand the November 9, 2011
waiver to Solar Saturn T-1301 turbine, serial number SDR-105092 under
the condition that a different turbine will be tested each year on a
three year rotation. If any tests exceeds 50 percent of the NOx
emission limits, all turbines will be required to conduct performance
tests.

Abstract for [1500051]

    Q: Can EPA approve an Alternative Monitoring Plan (AMP) for Envent
Corporation to conduct monitoring of hydrogen sulfide (H2S) emissions,
in lieu of installing a continuous emission monitoring system when
performing tank degassing and other similar operations controlled by
portable, temporary thermal oxidizers, at refineries in Region 6 States
that are subject to NSPS subparts J or Ja?
    A: Yes. EPA conditionally approves the AMP based on the description
of the process, the vent gas streams, the design of the vent gas
controls, and the H2S monitoring data furnished. EPA specifies the
proposed operating parameter limits and data which the refineries must
furnish as part of the conditional approval. The approved AMP applies
only to similar degassing operations conducted by ENVENT at refineries
in EPA Region 6.

    Q: Is the alternative monitoring plan (AMP) submitted to the
Tennessee Department of Environment and Conservation (TDEC) for the
distillation unit in Source B-99A-2 at the Eastman Chemical Company
(Eastman) facility in Kingsport, Tennessee acceptable?
    A: Yes. Based upon the information provided in the AMP by Eastman,
EPA determines that the AMP is acceptable since the proposed monitoring
parameters (water flow rate, propionic acid flow rate, and propionic
acid inlet temperature) will provide adequate assurance of compliance.
We agree that three of the parameters that the company would be
required to monitor under NSPS subpart NNN (propionic acid specific
gravity, water specific gravity, and water temperature) will not be
useful indicators of absorber performance for the source in question.
For ongoing compliance demonstration, EPA also provides guidance on how
to define excess emissions in terms of the alternative monitoring
parameters.

    Q1: Does a silo or frame structure enclosing a railcar loading
station at three separate Hi-Crush Proppant nonmetallic mineral
processing plants located in Augusta, Independence, and Blair,
Wisconsin meet the definition of a ``building'' under NSPS subpart OOO?
    A1: Yes. Based on Hi-Crush's representation that the enclosed
railcar loading stations are housed in structures with roofs, EPA
concludes that these structures would meet the definition of
``building'' in NSPS subpart OOO.
    Q2: Would the openings of those buildings be considered a ``vent''?
    A2: No. The building openings have no mechanically induced air flow
for the purpose of exhausting from a building.
    Q3: Since these railcar loading stations are contained in a
building, would the applicable particulate matter standard only be that
fugitive emissions from the building openings must not exceed 7 percent
opacity?
    A3: Yes. One emission limit option for an enclosed railcar loading
station that is itself enclosed in a building is to restrict fugitive
emissions from the building openings (except for vents as defined in 40
CFR 60.671) to 7 percent opacity, per section 60.672(e)(1).

    Q: Does EPA approve a waiver from the 40 part 60 subpart Ec
requirement to monitor the minimum pressure drop across a wet scrubber
that control emissions of acid gases (i.e., HCl) and is part of the
emission control system for the Stericycle hospital/medical/infectious
waste incineration (HMIWI) unit in Apopka, Florida? The Stericycle
HMIWI unit is equipped with a dry scrubber followed by a fabric filter
and a wet scrubber and with a selective noncatalytic reduction system.
All other applicable parameter monitoring requirements are proposed to
be met by the facility.
    A: Yes. EPA approves the waiver request since the removal of acid
gases is not dependent on the monitoring of wet scrubber minimum
pressure drop and all other applicable monitoring parameters for the
control system will be met. Monitoring of the other wet scrubber
monitoring parameters identified in Table 3 of subpart Ec (i.e., the
minimum scrubber liquor flow rate and the minimum scrubber liquor pH)
will indicate if the scrubber is working properly. Further, compliance
with the PM emission limit is achieved without the use of the wet
scrubber based on information.

Abstract for [1500058]

    Q: May an Alternative Monitoring Plan (AMP) be conditionally
approved for parametric monitoring in lieu of a continuous opacity
monitoring system (COMS) for a Wet Gas Scrubber (WGS) on a Fluidized
Catalytic Cracking Unit (FCCU) subject to NSPS subpart J, at the
Phillips 66 Company Alliance Refinery in Belle Chasse, Louisiana?
    A: Yes. Based on the information provided, EPA approves the AMP for
the proposed operating parameters conditioned on the source conducting
a performance test that demonstrates compliance and that establishes
the operating parameter limits (OPLs) for the WGS. EPA approves the two
proposed operating parameters, including the 1) minimum Liquid-to-Gas
(L/G) Ratio on a 3-hour rolling average basis; and, 2) minimum slurry
liquid circulation pump discharge pressure on a 3-hour rolling average
basis. The OPLs are to be recalculated based on the average of three
runs, provided the average PM emissions for the three runs meet the PM
emissions limit of the rule in pounds per kilopounds of coke processed.

    Q: Is Capitol One National Association required to petition the
Administrator under 40 CFR 60.4211(e) for approval to exceed the 100
hour readiness testing limit for emergency generators testing for
commissioning purposes under subpart IIII for internal compression
engines during the initial onsite commissioning process of its Data
Center in Chester, Virginia?
    A: No. A petition is not necessary or appropriate. When a new
greenfield source is under construction, subpart IIII allows emergency
generators to be used as needed to complete the construction process,
so long as Capitol One abides by the 100 hours limitation when the Data
Center is in commercial operation.

Abstract for [1500060]

    Q: Portland General Electric Company (PGE) seeks verification that
the emergency diesel-fired emergency generators at its Carver Readiness
Center in Clackamas, Oregon, run for 50 of 100 hours total use to
supply power,

allowed under NSPS subpart IIII and NESHAP subpart ZZZZ, can be part of
its Dispatchable Standby Generation (DSG) program.
    A: 40 CFR 60.4211 and 63.6640 authorize limited non-emergency use
of diesel engines that are classified and regulated as emergency
engines. EPA determines that the language in 40 CFR 63.6640 of subpart
ZZZZ regarding emergency engines dispatched under a financial
arrangement with another entity was not intended to prohibit utilities
from dispatching engines that they own and operate under the 50-hour
non-emergency operation option provided.

Abstract for [1500062]

    Q: Does EPA approve revisions to the Alternative Monitoring Plan
(AMP) for monitoring hydrogen sulfide (H2S) concentration and
determining the total reduced sulfur (TRS) concentration in the sour
gas routed to flares at the Lion Oil Company El Dorado (Lion Oil),
Arkansas Refinery, which are subject to NSPS subpart Ja?
    A: Yes. EPA conditionally approves Lion Oil's revised AMP, which
supersedes previous approvals to expand use of the approved AMP for
determining TRS under NSPS subpart Ja, and that includes additional
operating parameters, clarifications on sampling locations, and test
protocol specifications.

Abstract for [1500063]

    Q: Does EPA approve a revision to an Alternative Monitoring Plan
(AMP) that has been conditionally approved for the wet gas scrubber
(WGS) on a Fluidized Catalytic Cracking Unit (FCCU) at Marathon
Petroleum's refinery in Texas City, Texas subject to NSPS Part 60
subpart J, be resubmitted for approval of a revision based on an
additional operation mode at reduced charge rate?
    A: Yes. EPA conditionally approves the revision to the EPA-approved
AMP based on the additional information provided by Marathon to add an
additional mode of operation. The condition for approval requires
Marathon to conduct performance testing to demonstrate compliance and
to establish the operating parameter limits (OPLs) for the WGS at the
additional FCCU reduced charge rate, as established in the EPA response
letter.

Abstract for [1500064]

    Q: Does EPA approve alternate semiannual reporting periods under
section 60.5420(b) of NSPS subpart OOOO to run from April 1 through
September 30, and from October 1 through March 31, at the Atlas
Pipeline Driver Gas Plant in Midland, Texas?
    A: Yes. EPA approves the proposed alternate reporting schedule to
align the periodic reporting time period requirements of NSPS subpart
0000 since it does not extend the reporting period that would be
covered by the next semiannual report, as allowed under section
60.5420(b). The alternate reporting schedule does not extend the
reporting period that would be covered by the next semiannual.

Abstract for [1500065]

    Q1: Are the five City of Rock Island Public Works Department 880 HP
spark ignition natural gas fired engines (plus one offline spare) at
their wastewater treatment plant in Wisconsin considered emergency
engines under NSPS subpart JJJJ?
    A1: No. Since the engines would be operated approximately 16 times
per year for 270 hours, EPA determines that the engines do not meet the
definition of emergency stationary internal combustion engines.
Therefore, the engines are subject to subpart JJJJ.
    Q2: Can a waiver from performance testing be granted for the
engines?
    A2: No. EPA cannot grant a waiver of performance testing for these
engines, but due to the potential difficulties in testing, EPA
encourages the City to request alternative testing if necessary.

Abstract for [1500066]

    Q: May EPA approve an alternative to stack testing under NSPS
subpart JJJJ for nine identical non-certified Riverview bio-gas fueled
generators located on three farms (Riverview Dairy, West River Dairy,
and District 45 Dairy) in Minnesota?
    A: No. EPA does not approve any of the five alternative options
proposed by Riverview for its generators, which included: (1) exemption
from ongoing testing for engines that meet the standard, (2)
retroactive certification by the manufacturer, (3) self-certification
through testing, (4) provide certification to manufacturers that have
met the standards, and (5) test one engine and apply results to all
nine. However, EPA does provide two alternatives, Modified Option 1A
and 1B that could be used to demonstrate compliance. Modified Option 1A
is annual testing for NO, NOX, CO and O2 using a
portable analyzer. Modified Option 1B is to test each dairy's engine
sets at least once every three years, rotating annually on a three-year
cycle.

    Q: May an alternative test method be approved for Hawaiian Electric
Company's four new compression ignition engines subject to NSPS subpart
IIII at the Honolulu International Airport in Oahu that were certified
on diesel but will be operated on biodiesel?
    A: Yes. EPA determines that operation of the engines on biodiesel
would not void the certification if all of the following conditions are
met: the biodiesel meets the requirements of 40 CFR 60.4207(b), the
manufacturer's warranty includes the use of the biodiesel, and the
biodiesel meets ASTM D6751. The engines must also be installed,
configured, operated and maintained per the manufacturer's
instructions.

Abstract for [1500068]

    Q: Does EPA approve an Alternative Monitoring Plan (AMP) for
Evergreen Industrial Services (EIS) to conduct monitoring of hydrogen
sulfide (H2S) emissions in lieu of installing a continuous emission
monitoring system (CEMS), to monitor emissions controlled by portable
and temporary thermal oxidizers units (TOUs) during tank degassing and
other similar operations at refineries in Region 6 that are subject to
NSPS subparts J or Ja?
    A: Yes. Based on the description of the process, the vent gas
streams, the design of the vent gas controls, and the H2S monitoring
data furnished, EPA conditionally approves the AMP when EIA is
conducting degassing operations at refineries in Region 6 since it is
impractical to use a H2S CEMS in a portable TOUs. The EPA response
letter list the operating conditions for degassing operations and data
which the refineries must furnish to EIS as part of the conditional
approval.

Abstract for [1500069]

    Q: May Derenzo & Associates in Livonia, Michigan use a TECO Model
55C analyzer in lieu of Method 18 that will be used with Method 25A to
determine nonmethane organic compounds emitted from an internal
combustion engine subject to NSPS subpart JJJJ?
    A: Yes. EPA approves the request to use TECO Model 55C as an
alternative to Method 18 for measuring methane since it should produce
results similar to the ``cutter'' analyzers already allowed by the
regulation.

 Abstract for [1500071]

    Q: Does EPA approve the use by TRC Companies located in Lowell,
Massachusetts of a TECO Model 55C analyzer to measure non-methane
organic compounds (NMOC) from engines subject to NSPS subpart JJJJ?

    A: Yes. EPA approve TRC Companies request for use of the TECO Model
55C analyzer in lieu of Method 18 to measure NMOC from subpart JJJJ
engines, and the analyzer may be used by other engines subject to NSPS
subpart JJJJ. EPA will announce this as broadly applicable to all
stationary spark ignition combustion engines on our Web site at http://www.epa.gov/ttn/emc/trnethods.html#CatB).

 Abstract for [1500072]

    Q1: Does EPA conditionally approve a revision to a previously
approved Alternative Monitoring Plan (AMP) to allow for an automatic
sampling system, and an associated flow meter for collecting and
recording hydrogen sulfide (H2S) content, to be included for the West
Operations Ground Flare (Multi Jet Flare), which is part of a Flare Gas
Recovery System (FGRS) subject to NSPS subpart Ja, at the Motiva
Enterprises Norco Refinery in Norco, Louisiana?
    A1: Yes. EPA conditionally approves the AMP revision based on how
the automatic sampling system functions regarding the configuration and
operation of the FGRS. The H2S concentration of the combined
refinery fuel gas stream routed to the FGRS and the Multi Jet Flare was
less than 1 part per million. This satisfied EPA's condition for
approval that the H2S content shall be inherently low. Additionally,
the automatic sampling device samples the blended fuel gas stream
before it is sent to the Multi Jet Flare, and there are no crossover
points between the FGRS and other fuel gas streams. This satisfied
EPA's condition for approval that no crossover points shall exist in
the fuel gas vent stream going to the Multi Jet Flare. Based on review
by EPA Headquarters, Motiva also was authorized to use an alternate
test method for testing and analysis, which removed the previous
requirement to measure and record refinery fuel gas H2S concentrations
using the Length of Stain Tube method. EPA's ``Conditions for Approval
of the Alternative Monitoring Plan for Miscellaneous Refinery Fuel Gas
Streams, dated December 7, 1999, are incorporated by reference, except
for the monitoring provisions in Steps 1 through 7, as described in the
EPA response letter.
    Q2: What recordkeeping and report requirements are included in the
conditional approval?
    A2: Motiva shall maintain the H2S concentration data
from the sampling system and the alternate test method in the
laboratory information management system. The gas flow data from the
flow meter will be maintained in the electronic process data storage
system. Additional records shall be kept to note when the FGRS is
operating in either of two different scenarios. Quarterly reporting
must be submitted, except more frequently under certain circumstances,
as outlined in the conditional EPA approval letter.

 Abstract for [1500073]

    Q: May Derenzo & Associates in Livonia, Michigan use the TECO Model
55I analyzer (which is a newer version of the previously approved Model
55C) in lieu of Method 18 and Method 25A to determine non-methane
organic compounds (NMOC) emitted from RICE subject to NSPS subpart JJJJ
or NESHAP subpart ZZZZ?
    A: Yes. EPA approves the alternative testing request for NSPS
subpart JJJJ, provided that the facility follows all applicable
requirements in Method 25A for sample heating, appropriate test
procedures, calibration and standardization. Since NESHAP subpart ZZZZ
does not require the measurement of NMOC that part of the request is
not considered.

 Abstract for [1500074]

    Q: Can EPA confirm the proposed deadline for completing the initial
performance test under 40 CFR part 60 subpart Ec for the University of
Texas Medical Branch's medical infectious waste incinerator in
Galveston, Texas?
    A: Yes. EPA confirms that the initial compliance performance test
should be completed within 60 days of achieving maximum production
rate, and not later than 180 days after initial startup as required
under section 60.8 of the General Provisions.

 Abstract for [A150001]

    Q: Does the use of the Pre-Construction Survey, as described in
ASTM E2356-14 ``Standard Practice for Comprehensive Building Asbestos
Surveys,'' demonstrate compliance with the ``thorough inspection''
requirement at 40 CFR 61.145(a)?
    A: Yes. If an owner/operator follows the steps described in
Sections 1 through 5 and Section 8 in ASTM E2356-14 ``Standard Practice
for Comprehensive Building Asbestos Surveys'', it would provide a
thorough inspection of the facility. However, EPA would not accept the
Limited Asbestos Screen (i.e., Practice E2308) described in Section 1.5
as a substitute for the Comprehensive Building Asbestos Survey, and
would not consider the Limited Asbestos Screen as a thorough
inspection.

 Abstract for [C150001]

    Q: Do regulations related to ozone depleting substances under 40
CFR part 82 prohibit the use of Leak Stop to repair leaks in
residential air conditioning systems that contain chlorofluorocarbons?
    A: No. The use of aerosol chemical products such as Leak Stop are
not prohibited as long as there is no ``knowing venting'' or ``knowing
release'' of an ozone depleting substance taking place. We do not
currently have any information about the propellant used by the Leak
Stop product. However, if it is propelled by a Class I or II ozone
depleting substance, then it is banned under the non-essential products
exclusion found at 40 CFR 82.60.

 Abstract for [M150010]

    Q: Will EPA approve a waiver of the initial performance test
according to the provisions of 40 CFR 60.8(b)(4) and 63.7(h) for a new
chemset chamber subject to the NESHAP for Lead Acid Battery
Manufacturing, 40 CFR part 63 subpart PPPPPP, and the NSPS for Lead
Acid Battery Manufacturing, 40 CFR part 60 subpart KK, at the Johnson
Controls Battery Group Inc.'s (JCBGI''s) facility in Canby, Oregon?
    A: No. EPA is denying the requested waiver because the new unit is
not identical to the previously installed units and could have a
different capacity. While emissions are expected to be low, the initial
performance test is valuable to verify the installations of new
equipment.

 Abstract for [M150011]

    Q: Will EPA approve a National Security Exemption (NSE)for the
Department of Defense to waive the performance testing requirements for
twelve stationary diesel fired engines constructed between 2003 and
2009, all of which are subject to the National Emissions Standard for
Hazardous Air Pollutants for Stationary Reciprocating Internal
Combustion Engines (RICE) at 40 CFR part 63, subpart ZZZZ, while five
engines are also subject to the New Source Performance Standard for
Compression Ignition RICE at 40 CFR part 60, subpart IIII, which are
located at Fort Greely, Alaska?
    A: No. An NSE exemption is not necessary because 40 CFR part 63
subpart ZZZZ does not require performance testing for emergency
engines; according, an exemption from performance testing is not
necessary for these twelve engines if they meet the definition of
``emergency stationary RICE'' under subpart XXXX. In addition,

subpart IIII does not require performance testing for manufactured-
certified engines; accordingly, an exemption from performance testing
under subpart IIII is not necessary for the five manufactured-certified
engines located at Fort Greely.

 Abstract for [M150012]

    Q: Does EPA determine that the operation of an emergency generator
owned and operated by the Union Pacific Railroad's rail yard facility
in Lane County, Oregon is classified as a stationary source under
NESHAP subpart ZZZZ?
    A: No. EPA determines that the engine used to provide power
restoration for emergencies at railroad tunnels in Oregon is a portable
diesel generator. Because the engine has not provided power, or
operated for emergency use, or any other purpose other than testing at
the location where it has been stored for more than 12 months, it does
not meet the definition of stationary engine for that location under
subpart ZZZZ.

 Abstract for [M150013]

    Q1: Does EPA determine that 40 CFR part 63 subpart HHHHHH, National
Emission Standards for Hazardous Air Pollutants: Paint Stripping and
Miscellaneous Surface Coating Operations at Area Sources, apply to the
process of spray applying vehicle undercoating?
    A1: Yes. EPA determines the process of spray applying vehicle
undercoating is subject to NESHAP subpart HHHHHH. The undercoating
would be considered a coating under the NESHAP definitions and would
not be a sealant. It is generally spray-applied using a hand-held
device that creates an atomized mist of coating and deposits the
coating on a sub straight, just as are other automotive coatings.
    Q2: Does EPA determine that the exemption for facilities that do
not spray-apply target HAP-containing coatings is available to part of
a facility?
    A2: No. EPA determines that a facility that is not exempt must
satisfy the rule requirements for all of their spray-applied coating
operations. If the facility spray-applies no target HAP, then it may
request exemption from the rule.

 Abstract for [M150015]

    Q: Will EPA approve an alternative to the visible emissions
monitoring requirement of 40 CFR 63.11423(b) of the National Emission
Standards for Hazardous Air Pollutants (NESHAP) for Lead Acid Battery
Manufacturing Area Sources, subpart PPPPPP, for Johnson Controls
Battery Group Incorporated's facility in Canby, Oregon to shut down
equipment per permit conditions if any visible emissions are observed
rather than continuing to operate and conduct a Method 9 test?
    A: Yes. EPA approves this minor change in monitoring methodology
pursuant to 40 CFR 63.8(b)(i) because it will be more stringent than
that which is required according to 40 CFR 63.11423(b) by the NESHAP
standard.

 Abstract for [M150016]

    Q: Does 40 CFR part 63 subpart MMMMMM for Area Source Carbon Black
Production apply to Reklaim Technologies' tire reclamation facility at
the Port of Morrow near Boardman, Oregon?
    A: No. Based on the information provided by Reklaim, EPA determines
that the process at Reklaim's facility is materially different from the
``carbon black production'' process that is subject to subpart MMMMMM.
The process involves heating shredded tires in an oxygen starved
environment to recover carbon black, oil and steel from the tires. As
such the process does not fall within the definition of ``carbon black
production'' and is not subject to subpart MMMMMM.

 Abstract for [M150017]

    Q: The Olympic Region Clean Air Agency (ORCAA) in Port Angeles,
Washington asked if 40 CFR part 63 subpart HHHHHH for Paint Stripping
and Miscellaneous Surface Coating Operations apply to the process of
spray-applied truck bed lining.
    A: EPA determines that operations that spray-apply coatings to
truck bed liners, including color coatings, are subject to subpart
HHHHHH, based on the definitions of coatings and spray-applied coating
operations in 40 CFR 63.11180. Although the definition of ``truck bed
liner coating'' does exclude color coats, that definition is not
referred in 40 CFR 63.11170, the applicability section for subpart
HHHHHH. The lining operation is generally spray-applied using a hand-
held device that creates an atomized mist of coating and deposits the
coating on a substrate, just as are other automotive coatings.

 Abstract for [M150023]

    Q: Does EPA approve Holcim's particulate matter (PM) alternative
continuous parameter monitoring system (CPMS) plan for the common stack
venting exhaust emissions from different sources at their Portland
cement plant in Florence, Colorado, subject to the National Emission
Standards for Hazardous Air Pollutants From the Portland Cement
Manufacturing Industry, subpart LLL?
    A: Yes. Pursuant to 40 CFR 63.8(f)(2) and 63.1350(o)(4), EPA
conditionally approves the use of one PM CPMS on the common stack
whereby a site-specific operating limit is established that corresponds
to the results of performance testing demonstrating compliance with the
kiln and clinker cooler emission limits. The conditions for approval
are specified in the EPA response letter.

 Abstract for [M150024]

    Q: Does EPA approve an alternative monitoring plan that uses a
longer averaging time for inlet flow monitoring as a surrogate
parameter for monitoring methanol destruction in the Aeration
Stabilization Basin (ASB) subject to the National Emission Standards
for Hazardous Air Pollutants (NESHAP) from the Pulp and Paper Industry,
subpart S, at the Clearwater Paper Corporation, Cypress Bend Mill
located in McGehee, Arkansas?
    A: Yes. Based on the monitoring data provided by the company and
performance test results, EPA approves the AMP request. EPA agrees that
a daily flow is not representative of the actual hydraulic retention
time in the ASB, whereas a nine-day rolling average inlet flow
established per 40 CFR 63.453(n)(4) provides an actual representation
of the treatment system retention time.

 Abstract for [M150025]

    Q: Does EPA approve an alternative monitoring request to conduct
monthly pressure differential measurements across the catalyst at load
conditions within plus or minus 10 percent of the baseline load
established during the initial engine performance tests outlined in QEP
Field Services Company's (QEP) Consent Decree, rather than the plus or
minus 10 percent of 100 percent load as required in 40 CFR part 63
subpart ZZZZ for Stationary Reciprocating Internal Combustion Engines
located at Chapita, Coyote Wash, Island and Wonsits Valley Compressor
Stations?
    A: Yes. EPA conditionally approves the AMP request pursuant to
Sec.  63.8(t)(2) based on the performance testing negotiated as part of
the QEP Consent Decree. EPA believes that it is technically appropriate
to conduct the monthly pressure drop readings at plus or minus 10
percent of the load at an affected facility engine when the initial
performance test that was conducted is showing compliance with the MACT
ZZZZ. The conditions for approval are described in the EPA response
letter.

 Abstract for [M150026]

    Q: Do NSPS subpart IIII and NESHAP subpart ZZZZ apply to the engine
of a mobile power generator in Springdale, Arkansas that is designed to
supply electrical power on a temporary basis, at various locations
within the Kawneer Springdale Plant, and does not remain at any
location greater than 12 months?
    A: No. EPA determines that NSPS subpart IIII and NESHAP subpart
ZZZZ do not apply since this engine is considered a nonroad mobile
source. The mobile generator is a wheeled unit and its engine meets the
criteria for a nonroad engine that it be by itself or in or on a piece
of equipment that is portable or transportable. Furthermore, it will
not remain in a single location for longer than 12 consecutive months.

 Abstract for [M150027]

    Q1: Is the stationary gas compression reciprocating internal
combustion engine (RICE) at the Dimension Energy Company Coquille Bay,
Louisiana facility a remote affected source under 40 CFR part 63
subpart ZZZZ?
    A1: Yes. After reviewing the description of the RICE and its
operations, EPA determines that it is an existing area source which
meets the definition of a remote stationary RICE under 40 CFR 63.6675.
    Q2: What are the continuing compliance requirements for a remote
stationary RICE?
    A2: The operator must: Perform prescribed preventative maintenance
at certain intervals; maintain the RICE according to the manufacturer's
instructions; minimize startup time or develop a maintenance plan using
good air pollution prevention practices; and, maintain records to
demonstrate that applicable requirements have been completed.

Abstract for [M150028]

    Q: Does EPA agree that the Callidus Closed Loop Gasification System
(CCLGS) at the Del-Tin Fiber plant in El Dorado, Arkansas is exempt
from the Boiler MACT, subpart DDDDD under the exemption at 40 CFR
63.7491(h) because it is subject to and complying with the Plywood
MACT, subpart DDDD?
    A: No. The EPA determines that both the Boiler MACT and the Plywood
MACT apply to specific components of the CCLGS based on a review of the
design and operation information available for the Del-Tin Fiber
facility, so the exemption at 40 CFR 63.7491(h) does not apply. The
rotary gasifiers and secondary combustion chamber (SCC) are considered
affected sources, specifically defined as ``process heaters'' under the
Boiler MACT when combustion gases are not used to directly heat process
material. The portion of combustion gases that directly flow through
the dryer units are considered affected sources under the Plywood MACT
(Sec.  63.2232(b) and Sec.  63.2292) and are thereby exempted from the
Boiler MACT requirements (Sec.  63.7491(1)). However, any combustion
gases from the rotary gasifiers and the SCC that bypass the dryer units
and are used for indirect heat transfer to process material or to heat
transfer material for use in a process unit are subject to the Boiler
MACT (Sec.  63.7575).

 Abstract for [M150029]

    Q: Does EPA agree to accept data from a prior performance test in
lieu of a new performance test to demonstrate initial compliance with
40 CFR part 63 subpart ZZZZ for six natural gas fueled spark plug
ignition engines at the ExxonMobil Chemical facility in Baton Rouge,
Louisiana?
    A: Yes. EPA accepts a previous performance testing for six engines
conducted in lieu of implementing an initial test. The testing was done
using the same methods specified in subpart ZZZZ, and was conducted
within two years of the performance test deadline. Additionally, the
equipment was not modified following the April 2012 testing.

 Abstract for [M150030]

    Q: Does EPA agree that the RockTenn Hodge Mill Boiler in Hodge,
Louisiana is a biomass hybrid suspension grate boiler under 40 CFR part
63 subpart DDDDD?
    A: Yes. EPA agrees that the boiler is subject to NESHAP subpart
DDDDD since the description provided meets the definition of a hybrid
suspension grate boiler found in the rule. Since natural gas and tire
derived fuel (TDF) are also used, the facility must keep records to
demonstrate the annual average moisture content is at or above 40
percent. The facility must use natural gas for startup, shutdown, and
flame stabilization, and use TDF when excessively firing wet biomass
fuel.

 Abstract for [M150031]

    Q: Are three Electric Utility Generating Units (EUGUs) located at
the Lafayette Utilities System (LUS) Doc Bonin Electric Generating
Station in Lafayette, Louisiana considered to be affected sources with
gas-fired boilers that are not subject to Boiler Area Source MACT,
subpart JJJJJJ?
    A: EPA determines that the boilers are not affected sources subject
to the Boiler Area Source MACT if all conditions at 40 CFR 63.11237 are
met. Gas-fired boilers are excluded from subpart JJJJJJ per 40 CFR
63.11195(e). A permit limitation is necessary to verify applicability
requirements are met for each EUGU for burning fuel oil only during
natural gas curtailment, and to not exceed testing hours with fuel oil
during any calendar year.

    Q1: Does EPA approve an Alternative Monitoring Plan (AMP) for three
Reciprocating Internal Combustion Engines (RICE) subject to NESHAP
subpart ZZZZ at the Occidental Permian Terrill Gas Treating Facility
for testing at less than 100 percent maximum load?
    A1: Yes. EPA approves Occidental Permian proposed AMP for a lower
engine load be set as a maximum load for compliance demonstration.
Specifically, we approve performance testing at the alternate lower
maximum engine load with monitoring required at plus or minus 10
percent. The three RICE cannot operate at 100 percent load due to site-
specific operations at the facility, and therefore cannot be tested at
100 percent plus or minus 10 percent operational capacity, as specified
at 40 CFR 63.6620(b)(2). If operations change such that the maximum
load of the engines exceeds the alternative lower maximum load, the AMP
approval will be terminated, and retesting will be required to
demonstrate compliance with NESHAP subpart ZZZZ at the higher engine
load.

    Q: Does EPA agree that the backup power generator at the Freddie
MAC facility in Carrollton, Texas is classified as an existing
commercial emergency stationary Reciprocating Internal Combustion
Engine (RICE) that is not subject to 40 CFR part 63 subpart ZZZZ?
    A: Yes. EPA determines that the Freddie MAC facility is an area
source with a commercial NAICS code, and the backup power generator
meets the exemption provided at 40 CFR 63.6585(f)(2) applicable to
emergency stationary RICE operated at an area source. This RICE, used
solely for backup power generation, have not exceeded 50 hours for any
activities during any one year period within the past two year period.

    Q: Will EPA provide a waiver to CertainTeed Corporation of the 60-
day requirement under 40 CFR 63.9(c) to notify EPA in advance of the
initial

performance test at the GS Roofing facility in Portland, Oregon?
    A: Yes. EPA is granting a waiver of the 60-day requirement for a
notification prior to the initial performance test pursuant to 40 CFR
63.9(i) of the 40 CFR 63.9(c) requirement to enable testing during
facility's highest volume period with the maximum ambient temperature,
which is will occur in less than 60 days. This would enable the
estimation of what the emissions are during a worst case scenario to
test the limits of our system.

    Q: Does 40 CFR part 61 subpart N apply to the Bullseye Glass
Company's manufacture of colored art glass in its Portland, Oregon
facility?
    A: Yes. NESHAP subpart N applies to the company's manufacture of
colored art glass. According to 40 CFR 61.160(a), 40 CFR part 61
subpart N does not apply to pot furnaces but rather to each glass
melting furnace that uses commercial arsenic as a raw material.
However, based on information provided by Bullseye Glass including
descriptions, photos and diagrams, EPA determines that the vessels used
by Bullseye do not meet the definition of pot furnaces because they are
not sealed off from the furnace atmosphere so that there is potential
for emissions to escape with the furnace exhaust.

    Q: Are boilers/engines/marine equipment on a liquefied natural gas
carrier (LNGC) at the proposed Aguirre Gasport located approximately 3
miles offshore of the Puerto Rico Electric Power Authority subject to
NSPS and NESHAP standards when the LNGC will be converted into a
Floating Storage and Regasification Unit (FSRU) to be permanently
moored at the GasPort?
    A: Yes. Based on the information provided, EPA determines that the
FSRU is a stationary source because it utilizes boilers as the main
propulsion devices instead of reciprocating internal combustion engines
(RICE) and it will be permanently moored, except when there is a need
to take the unit to safer water due to and special circumstances.
Therefore, the affected equipment on the FSRU, except for non-
reciprocating internal combustion engine (RICE), is subject to NSPS and
NESHAP standards. All non-reciprocating RICE equipment on the FSRU is
not a stationary sources because it falls under the definition of
nonroad engines as they will be used on self-propelled equipment.
Therefore, the NSPS and NESHAP do not apply to the nonroad RICE.
However, the nonroad RICE must comply with the applicable nonroad
engine standards in 40 CFR parts 89, 94, 1039, 1042, 1043, 1045, 1048,
1054, 1065, and 1068, if applicable. Specific questions on the
requirements and applicability of a particular NSPS and NESHAP rules
can be discussed separately on a case-by-case basis as the need arises.

    Q: Are the 39 emergency stationary reciprocating internal
combustion engines (RICE) at Los Alamos National Laboratory (LANL) area
source facility subject to RICE NESHAP requirements?
    A: No. EPA determines that the 39 emergency RICE at LANL are not
subject to the RICE NESHAP because they are located at an area source
that is classified as an ``institutional'' facility. The RICE rule
excludes existing stationary emergency engines located at residential,
commercial, or institutional facilities that are area sources of HAP.
Note that the engines must meet the definition of ``Emergency
stationary RICE'' in 40 CFR 63.6675.

 Abstract for [Z150006]

    Q: Northern Natural Gas based in Omaha, Nebraska asked that, under
40 CFR 63.6625(h), part 63 NESHAP subpart ZZZZ for spark ignition
reciprocating internal combustion engines (RICE) regarding minimizing
engine idle time, if an engine does not complete start up within the
thirty minute time limit, are there any restrictions on initiating
another startup of the engine and/or the time frame to complete the
subsequent startup?
    A: No. An engine does not need to be shut off if it does not
complete startup within thirty minutes. However, any further activity
after thirty minutes is considered part of normal operation. Multiple
startups should be counted as separate events with a thirty minute time
limit per event. If startups occur consecutively with short durations
in between, they could be considered as one startup since startups are
part of a single occasion where the engine is working up to normal
operations.

    Q1: May emergency Reciprocating Internal Combustion Engines (RICE)
that currently do not qualify for the exclusion in 40 CFR 63.6585(f)(2)
because they are contractually obligated to be available for more than
15 hours for the purposes specified at 40 CFR 63.6640(f)(2)(ii) and
(iii) and (f)(4)(ii), later qualify for exclusion once those contracts
expire, provided that the other conditions of 40 CFR 63.6585(f)(2) are
met?
    A1: If an emergency stationary RICE does not meet the conditions
for the exclusion in 40 CFR 63.6585(f)(2) as of the compliance date,
then it is subject to subpart ZZZZ at the date of compliance. However,
if the engine's status subsequently changes to meet the conditions of
40 CFR 63.6585(f)(2) after the compliance date, the engine would no
longer be subject to subpart ZZZZ.
    Q2: Can emergency RICE located at area sources continue to
participate in peak shaving programs for up to 50 hours per year until
May 3, 2014 without losing their emergency engine status?
    A2: An emergency stationary RICE located at an area source of HAP
emissions can be used for peak shaving for up to 50 hours per year
until May 3, 2014 if the engine is operated as part of a peak shaving
(load management program) with the local distribution system operator
and the power is provided only to the facility itself or to support the
local distribution system. This is the case whether or not the engine
will be retrofitted to comply with the subpart ZZZZ standards for non-
emergency engines.
    Q3: Do 40 CFR 63.6640(f)(4)(i) and (ii) address separate and
distinct non-emergency situations, and does the ``local reliability''
exception set forth in 40 CFR 63.6640(f)(4)(ii) have no sunset
provision?
    A3: Yes. 40 CFR 63.6640(f)(4)(i) and (ii) are separate and distinct
situations and there is no sunset provision for the operation specified
in Sec.  63.6640(f)(4)(ii). An emergency stationary RICE at an area
source of HAP emissions can continue to operate for up to 50 hours per
calendar year for the purpose specified in Sec.  63.6640(f)(4)(ii)
beyond May 3, 2014.
    Q4: How does EPA interpret 40 CFR 63.6640(f)(4)(ii)(A), which
requires that to qualify for the 50 hour exemption, the emergency RICE
must be dispatched by the local balancing or local transmission and
distribution system operator?
    A4: If the local transmission and distribution system operator
informs the facility that they will be cutting their power, which, in
turn, causes the facility to engage its emergency stationary RICE, the
engine would be considered dispatched by the local transmission and
distribution system operator.

    Q1: What date is used under NESHAP subpart ZZZZ to determine if
engines located at Allison Transmission Indianapolis facility in
Indiana, are ``existing'' or ``new''?

    A1: The rule uses the date that the engine commenced construction
to determine if the engine is existing or new. The General Provisions
to 40 CFR part 63 define both ``construction'' and ``commenced'' and
those definitions are applied to the subpart.
    Q2: Does NESHAP subpart ZZZZ apply to an engine that has been
rebuilt, specifically where the engine core is reused, but components
such as pistons, rings and bearings are reconditioned or replaced?
    A2: A rebuilt engine would need to be evaluated to determine if
reconstruction had occurred. The General Provisions to part 63 defines
``reconstruction.''

 Abstract for [Z150011]

    Q: Are the emergency engines located at the NASA Langley Research
Facility in Hampton, VA subject to NESHAP subpart ZZZZ for
Reciprocating Internal Combustion Engines?
    A: No. EPA determines that the emergency engines are located at a
facility that is an area source and classified as an ``institutional''
facility. Therefore, under 40 CFR 63.6590(b)(3), emergency engines at
the facility are exempt from requirements under NESHAP subpart ZZZZ.

 Abstract for [1600004]

    Q: Does EPA accept the industry coalition request to rescind a
November 21, 2007, letter to the National Grain and Feed Association in
which EPA stated that temporary storage facilities meet the definition
of ``permanent storage capacity'' under 40 CFR part 60, subpart DD,
NSPS for Grain Elevators (Subpart DD), and required it be included when
determining applicability of Subpart DD for a particular facility?
    A: Yes. The EPA is proposing revisions to Subpart DD and has also
decided to re-evaluate the rationale for the November 21, 2007 letter.
While the definition of ``permanent storage capacity'' in Subpart DD is
broad, we are now aware that temporary storage facilities (TSFs)
generally handle the grain less time throughout the year than other
types of permanent storage facilities and may require different
treatment. Also, while not dispositive as to the applicability of the
rule to these units, we note that TSFs did not exist during the
development of Subpart DD, and their processes and handling techniques
were not specifically considered during the rulemaking process. For
these reasons, EPA rescinds the November 21, 2007 letter. As a result,
TSFs do not meet the definition of ``permanent storage capacity'' under
Subpart DD and should not be included when determining applicability
under Subpart DD for a particular facility.

    Dated: February 25, 2016.
