ENVIRONMENTAL PROTECTION AGENCY
[FRL-7451-9]
Recent Posting to the Applicability Determination Index (ADI)
Database System of Agency Applicability Determinations, Alternative
Monitoring Decisions, and Regulatory Interpretations Pertaining to
Standards of Performance for New Stationary Sources, National Emission
Standards for Hazardous Air Pollutants, and the Stratospheric Ozone
Protection Program
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of availability.
-----------------------------------------------------------------------
SUMMARY: This notice announces applicability determinations,
alternative monitoring decisions, and regulatory interpretations that
EPA has made under the New Source Performance Standards (NSPS), 40 CFR
part 60; the National Emission Standards for Hazardous Air Pollutants
(NESHAP), 40 CFR parts 61 and 63; and the Stratospheric Ozone
Protection Program, 40 CFR part 82. This notice also clarifies the
Notice of Availability published in the Federal Register on November
15, 2001 (66 FR 57453).
FOR FURTHER INFORMATION CONTACT: An electronic copy of each complete
document posted on the Applicability Determination Index (ADI) database
system is available on the Internet through the Office of Enforcement
and Compliance Assurance (OECA) Web site at: http://www.epa.gov/compliance/assistance/applicability.
The document may be located by
date, author, subpart, or subject search. For questions about the ADI
or this notice, contact Maria Malave at EPA by phone at: (202) 564-
7027, or by email at: malave.maria@epa.gov. For technical questions
about the individual applicability determinations or monitoring
decisions, refer to the contact person identified in the individual
documents, or in the absence of a contact person, refer to the author
of the document.
SUPPLEMENTARY INFORMATION: Background: The General Provisions to the
NSPS in 40 CFR part 60 and 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 broadly termed applicability determinations. See 40 CFR
60.5 and 61.06. Although the 40 CFR part 63 NESHAP and section 111(d)
of the Clean Air Act regulations contain no specific regulatory
provision that sources may request applicability determinations, EPA
does respond 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 which 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 broadly termed 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 broadly
termed regulatory interpretations.
EPA currently compiles EPA-issued NSPS and NESHAP applicability
determinations, alternative monitoring decisions, and regulatory
interpretations, and posts them on the Applicability Determination
Index (ADI) on a quarterly 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 an electronic
index on the Internet with over one thousand EPA letters and memoranda
pertaining to the applicability, monitoring, recordkeeping, and
reporting requirements of the NSPS and NESHAP. The letters and
memoranda may be searched by date, office of issuance, subpart,
citation, control number or by string word searches.
Today's notice comprises a summary of 55 such documents added to
the ADI on December 20, 2002. The subject, author, recipient, date and
header of each letter and memorandum are listed in this notice, as well
as a brief abstract of the letter or memorandum. Complete copies of
these documents may be obtained from the ADI through the OECA Web site
at: http://www.epa.gov/compliance/assistance/applicability.
Clarification to November 15, 2001 Notice of Availability
EPA has received questions regarding the applicability of the
documents whose availability was noticed in the November 15, 2001
Notice of Availability (66 FR 57453). EPA has reviewed those documents,
and through today's notice clarifies that to the extent any of those
documents constituted ``final action of the Administrator'' for
purposes of section 307(b)(1) of the Clean Air Act, they were not
``nationally applicable'' actions within the meaning of section
307(b)(1). For purposes of establishing venue for judicial review of
any such document, the document may be considered a ``local or
regionally applicable'' action as that phrase is employed in section
307(b)(1).
Summary of Headers and Abstracts
The following table identifies the database control number for each
document posted on the ADI database system on December 20, 2002; the
applicable category; the subpart(s) of 40 CFR parts 60, 61, or 63 (as
applicable) covered by 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.

Abstract
Abstract for [A020001]:
Q1: Are residential structures owned by the State subject to the
asbestos NESHAP if they have less than four dwelling units?
A1: Yes, if the structures are part of a State project such as road
construction or urban renewal.
Q2: Is spray on ceiling texture considered part of the wall system
like tape joint compound?
A2: No. The analyses of these individual layers may not be
composited with the wallboard analyses.
Q3: If the ceilings are not disturbed or demolished during the
move, does the asbestos need to be removed before the move?
A3: Prior to the move, the owner or operator must determine if the
move will break up, dislodge, or similarly disturb the asbestos. If
such disturbances occur, the owner or operator may be subject to
enforcement action.
Q4: Can the State avoid the requirements of the asbestos NESHAP by
having the demolition of a residential structure occur prior to the
State taking official ownership?
A4: If the structure is part of an installation, as occurs when a
group of houses are demolished for a project, such activities would be
considered
[[Page 7375]]
circumvention which is prohibited by the part 61 NESHAP general
provisions.
Q5: Is the movement of a single-family home purchased from a
private party subject to the asbestos NESHAP?
A5: No, unless the home is part of an installation, planned
development, or public project.
Q6: Is the movement of a single-family home purchased from a land
developer subject to the asbestos NESHAP?
A6: Yes. Residential structures that are demolished or renovated as
part of a commercial or public project are not exempt from the rule.
Q7: Is the movement of a structure that has been used for
educational purposes and will contain four or less dwelling units
subject to the asbestos NESHAP?
A7: Yes. Mobile classroom structures are considered institutional
buildings.
Q8: Is the movement of a single-family home (not modular or mobile)
purchased from a house manufacturing company subject to the asbestos
NESHAP?
A8: No, based on the limited information provided.
Q9: Is the movement of portable school classrooms subject to the
asbestos NESHAP?
A9: Yes. Large mobile structures for public or commercial use are
regulated.
Q10: Is the movement of agricultural buildings subject to the
asbestos NESHAP?
A10: Agricultural buildings used for commercial purposes, such as a
dairy barn or crop storage structure, are subject. However, the rule
does not apply to sheds used to store equipment for a homeowner's
garden, or to farm stands that sell fresh produce and have no
utilities.
Q11: Is the movement of garages subject to the asbestos NESHAP?
A11: Yes, if the residential structure associated with the garage
is subject, if the garage is located at a commercial operation, or if
the garage itself is used for commerce.
Abstract for [M020008]:
Q: Will EPA approve an alternative scrap inspection monitoring
program for a facility that accepts no fabrication or press scrap
containing paint or coatings?
A: Yes, provided the facility includes a recordkeeping provision
like 40 CFR 63.1510(p)(6).
Abstract for [M020009]:
Q: Can the Boise Cascade paper mill in International Falls,
Minnesota use the UNOX system biomass, as calculated using the mixed
liquor volatile suspended solids (MLVSS), to meet the continuous
monitoring requirements for kraft pulping condensates? The pulp and
paper NESHAP does not specify a monitoring parameter for closed
biological systems.
A: Yes. The UNOX system destruction efficiency depends on the
number of biological organisms in the system, the biomass accounts for
the majority of organic solids, and MLVSS is a measure of organic
solids. Boise Cascade must use the average MLVSS measured during a
compliant performance test as the minimum MLVSS demonstrating
continuous compliance.
Abstract for [M020010]:
Q: Will EPA waive the performance test for a backup portable vapor
combustion unit that Marathon Ashland Petroleum (MAP) has used at its
St. Paul Park, Minnesota refinery to control VOC emissions from a
gasoline loading rack during maintenance and repair work on the primary
carbon adsorption unit controls?
A: Yes. Tests showed that the unit's VOC emissions were only 15
percent of the emission standard at another MAP location. The unit is
scheduled for use at other MAP facilities, and bringing it back to St.
Paul Park for a test would not provide any new information.
Abstract for [M020011]:
Q: What is the correct location for measuring freeboard
refrigeration temperature in a halogenated solvent cleaning machine?
A: The temperature should be measured in the center of the chilled
air blanket, at the center cooling coil of the machine.
Abstract for [M020012]:
Q: Is a facility that includes a chamber that delaminates aluminum
foil from paper and plastic subject to the secondary aluminum NESHAP?
A: No. Subpart RRR defines a scrap dryer as a unit used to remove
organic contaminants from aluminum scrap prior to melting. No melting
occurs at the facility in question, and there are no other affected
sources subject to subpart RRR.
Abstract for [M020013]:
Q: Will EPA approve surrogate parameters for daily monitoring of an
open biological treatment system?
A: Yes, based on the information submitted, EPA approves the
request. However, EPA may require use of another specified monitoring
method if it finds reasonable grounds to dispute the results obtained
under this alternative monitoring method.
Abstract for [M020014]:
Q: A refinery has process area reactors and distillation columns
whose only gas streams are combusted in the refinery's fuel gas system.
These gas streams are exempt from any compliance monitoring
requirements under 40 CFR part 63, subpart G. Does 40 CFR 63.110(d)(10)
also exempt those gas streams from the requirements of NSPS subparts
NNN and RRR?
A: No. 40 CFR 63.110(d)(10) does not exempt the gas streams from
meeting the requirements of NSPS subparts NNN and RRR.
Abstract for [M020015]:
Q: Do the halogenated solvent cleaner NESHAP standards apply to the
process described for stripping epoxy resins from steel bowls?
A. The applicability section of this rule, 40 CFR 63.460(a), states
that if any of the named solvents, including methylene chloride, which
this facility uses, is used in any of four types of solvent cleaning
machines as a cleaning and/or drying agent, then the subpart applies.
Although the hand cleaning portion of the removal of the epoxy resin
from the steel bowl is exempt from Subpart T, the mechanical cleaning
inside the custom design tank is not exempt, but rather is an
applicable batch cold cleaning machine under the halogenated solvent
MACT standard.
Abstract for [M020016]:
Q: Do the halogenated solvent cleaner NESHAP standards apply to the
stripping (thinning/diluting) of a coating of catalyzed epoxy resin in
various stages of cure from metal bowls in the following process? The
metal bowl is placed upside down in a custom designed tank containing
approximately 3'' of Methylene Chloride liquid. The tank cover is
closed and spray is directed upward into the part in a 45 minute
stripping process. The parts are removed and then hand cleaned about 15
minutes per bowl. Is this a cold cleaning operation or a stripping
operation?
A: 40 CFR 63.461 defines a cold cleaning machine as any device or
piece of equipment that contains and/or uses liquids, into which parts
are placed to remove soils from the surface of the parts. In this case,
the cleaning of the parts once they exit the solvent bath using spray
headers to begin the stripping process and then the continued cleaning
of parts by hand would identify this operation as a stripping
operations. Based on the information supplied, EPA has determined that
the operation is not subject to the halogenated solvent cleaning
NESHAP.
Abstract for [M020017]:
Q1: USGC Almeg has a processing chamber in which foil is
delaminated from paper and plastic. This processing chamber operates at
a maximum temperature of 900 degrees Fahrenheit; no melting occurs
here, nor does melting occur subsequently in any of
[[Page 7376]]
USGC Almeg's operations. Is USGC Almeg subject to subpart RRR?
A1: Yes. Units that use heat to remove contaminants from scrap
aluminum are subject to 40 CFR part 63, subpart RRR, irrespective of
whether the aluminum is subsequently melted.
Q2: USGC Almeg has a unit that dries aluminum chips in the absence
of any melting of aluminum at the site. Is the unit subject to subpart
RRR?
A2: Yes. A device that uses heat to evaporate water, oil, or oil/
water mixtures from unpainted/uncoated aluminum chips is subject to the
requirements of subpart RRR.
Abstract for [M020018]:
Q: What is the correct wastewater classification of low-point
drains which are drained on a routine basis as part of proper function
of the process?
A: The procedures followed by Celanese result in process wastewater
because the draining of the wastewater is essential to maintaining the
proper function of the process equipment; the draining occurs at a
frequent, routine, planned interval; and the draining is not done for
the purposes of maintenance or repair.
Abstract for [M020019]:
Q: Will EPA approve an alternative initial performance test for
roller mill transfer chutes at a Portland cement facility?
A: Yes. Because of the design and operation of the chutes and the
nature of the material being processed, EPA believes that emissions are
not likely and accordingly approves the request for an alternative
initial performance test.
Abstract for [M020020]:
Q: Will EPA approve alternative monitoring using a bag leak
detection system in lieu of daily visual observations for finish mill
stacks?
A: Yes. EPA approves a request for the use of a bag leak detection
system (BLDS) in lieu of daily visual observations on finish mill
stacks.
Abstract for [M020021]:
Q: Will EPA approve a waiver from Method 9 initial performance
testing for transfer chutes, load spouts and Magnetic Separator
Discharge Chute at a Portland cement facility?
A: EPA approves the waiver from Method 9 for transfer chutes, load
spouts and Magnetic Separator Discharge Chute at the facility on
condition that any change in operation will require further EPA review.
Abstract for [M020022]:
Q: Will EPA approve a waiver from Method 9 initial performance
testing and monitoring for the coal mill stack and related air
pollution control device at a Portland cement facility?
A: Yes. EPA approves a waiver of performance testing and
alternative monitoring for the coal mill stack. Performance test
requirements and the monitoring requirements shall be applicable to the
main kiln stack and its related air pollution control device.
Abstract for [0200050]:
Q: Can Consolidated Edison Energy Massachusetts obtain a relaxed
sulfur-in-fuel monitoring schedule under NSPS subpart GG for the
operation of two stationary gas turbines which operate solely on
natural gas?
A: Yes, EPA routinely grants custom monitoring schedules under 40
CFR part 60, subpart GG for units burning low sulfur fuels.
Abstract for [0200051]:
Q: Can Consolidated Edison Energy Massachusetts obtain a waiver
from the requirement to conduct an initial performance test for
NOX under 40 CFR part 60, subpart GG?
A: Yes, EPA will waive the performance test requirement where it
believes that the source can demonstrate compliance with the standard
using other means. In this case, the source will demonstrate compliance
with the subpart GG NOX limit by installing, operating, and
maintaining a NOX continuous emission monitoring (CEM)
system in accordance with 40 CFR part 75, and conducting an initial
RATA certification for the CEM system.
Abstract for [0200052]:
Q: Can Massachusetts Institute of Technology obtain a relaxed
sulfur-in-fuel monitoring schedule under NSPS subpart GG for the
operation of a stationary gas turbine which operates solely on natural
gas?
A: Yes, EPA routinely grants custom monitoring schedules under 40
CFR part 60, subpart GG for units burning low sulfur fuels.
Abstract for [0200053]:
Q: Can Sithe's Fore River and Mystic facilities obtain a relaxed
sulfur-in-fuel monitoring schedule under NSPS subpart GG for the
operation of stationary gas turbines with a primary fuel of natural gas
and a secondary fuel of very-low sulfur distillate oil?
A: Yes, EPA routinely grants custom monitoring schedules under 40
CFR part 60, subpart GG for units burning low sulfur fuels.
Abstract for [0200054]:
Q: May Sithe's Fore River and Mystic facilities measure nitrogen
oxides (NOX), sulfur dioxide (SO2), and
particulate matter (PM) at the heat recovery steam generator (HRSG)
outlet instead of measuring upstream and downstream of the duct burner
during the subparts GG and Da initial performance test? Also, may Sithe
use method 20 instead of method 7E for the initial performance test?
Can Sithe obtain a custom CEMS quality assurance/quality control (QA/
QC) regimen?
A: Yes, EPA has determined that in these specific cases the
proposed alternatives to the test methods, sampling points, and CEMS
QA/QC requirements will continue to ensure compliance with the emission
limits.
Abstract for [0200055]:
Q: Contrary to what is required under 40 CFR 60.153(b)(2), subpart
O, is it permissible to locate an oxygen monitor downstream of any
multiple hearth incinerator rabble shaft cooling air inlet into the
incinerator exhaust gas stream, fan, ambient air recirculation damper,
or any other source of dilution air?
A: Yes, providing certain conditions are met. EPA has concurred
with a multiple hearth incinerator owner/operator's determination that
a stack gas extractive oxygen CEMS can provide a valid surrogate
indicator of incinerator exhaust gas oxygen content with minimal
interference from sources of dilution air, provided certain testing and
operation and maintenance (O&M) practices are implemented, including
reporting requirements.
Abstract for [0200056]:
Q: Will EPA exempt the U.S. Navy under 40 CFR 60.332 for a new
Turbine Test Facility to be installed in the City of Philadelphia?
A: Yes, Region III approves the exemption from the nitrogen oxides
standard in subpart GG because this new installation meets the
conditions specified in 40 CFR 60.332 as both a military turbine
installation and a manufacturer test facility for efficiency
improvements and emissions reductions.
Abstract for [0200057]:
Q: Does EPA consider a ``drop out'' box with water sprays an
example of a wet scrubbing control device?
A: Yes. The Stationary Source Control Techniques Document for Fine
Particulate Matter (EPA, 1998) defines wet scrubbers as ``particulate
matter (PM) control devices that rely on direct and irreversible
contact of a liquid with the PM.'' Therefore, a ``drop-out'' box with
water sprays is considered to be an example of a wet scrubbing control
device and should be in compliance with the regulations accordingly.
Abstract for [0200058]:
Q: Will EPA approve an alternative testing procedure for four
simple cycle combustion turbines that use a certified continuous
emission monitor that has been certified under 40 CFR part 75?
A: The owner has demonstrated that the concentration of oxygen is
not
[[Page 7377]]
stratified across the diameter of the exhaust stack. Therefore, subject
to certain conditions, EPA approves this request.
Abstract for [0200059]:
Q: Will EPA approve an alternative monitoring plan for a portable
combustor at the gasoline loading rack at Marathon Ashland Petroleum
LLC's Detroit, Michigan refinery?
A: Yes. Because the request is consistent with EPA's policy for
approval of an alternative monitoring plan for miscellaneous fuel gas
streams, EPA approves the request.
Abstract for [0200060]:
Q1: Does the replacement of an air grid on an FCCU catalyst
regenerator trigger NSPS subpart J?
A1: If the Air Grid Replacement Project does not cause an increase
in the emission rate of PM, SO2, or CO, as presented by MAP,
it will not trigger NSPS. MAP is required to demonstrate that there
will be no emission increase via CEM data and emissions tests.
Q2: Does the Air Grid Replacement Project qualify for the exemption
of modification for routine maintenance, repair, and replacement in 40
CFR 60.14(e)(1)?
A2: No. The Air Grid Replacement Project is not a regular,
customary or standard undertaking for the purposes of maintaining the
plant in its present condition.
Abstract for [0200061]:
Q: Will EPA approve a higher operating temperature for ten wells at
a landfill?
A: Yes. Based on the supporting information presented by the
landfill, it appears that the methanogenic process is still at an
anaerobic phase at the higher landfill gas temperatures and no evidence
of subsurface landfill fire is present at the site.
Abstract for [0200062]:
Q: Will EPA grant a coal preparation plant a waiver from the NSPS
general provision reporting and recordkeeping requirements for all of
its coal handling system, except the dust collector?
A: No. The NSPS general provisions do not provide for the complete
waiving of such reporting or recordkeeping requirements.
Abstract for [0200063]:
Q: Will EPA grant a waiver from the NSPS general provision
reporting and recordkeeping requirements for a coal mine's processing
and conveying equipment?
A: No. The NSPS general provisions do not provide for the complete
waiving of such reporting or recordkeeping requirements.
Abstract for [0200064]:
Q: At what point does the custody transfer exemption apply to
petroleum liquid storage vessels in natural gas production processes?
A: There is no set point for every facility where the custody
transfer exemption applies. If the petroleum liquid storage vessels are
located after any type of processing or treatment, the custody transfer
exemption does not apply. It is possible that the custody transfer
exemption may apply to different facilities at different points in the
natural gas production process.
Abstract for [0200065]:
Q1: Are turbines manufactured before October 3, 1977 and maintained
by Alyeska before that date, but that did not begin initial operation
on the Trans-Alaska Pipeline System (TAPS) until after that date
subject to NSPS subpart GG?
A1: In the case of stationary gas turbines that are mass-produced
and purchased in completed form, EPA considers the manufacturer as the
original owner or operator. The turbines are not subject to subpart GG
provided that they were not modified or reconstructed after October 3,
1977.
Q2: Are turbines manufactured before October 3, 1977 and not
purchased by Alyeska until after that date, and that therefore did not
begin initial operation on the TAPS until after that date subject to
subpart GG?
A2: In the case of stationary gas turbines that are mass-produced
and purchased in completed form, EPA considers the manufacturer as the
original owner or operator. The turbines are not subject to subpart GG
provided that they were not modified or reconstructed after October 3,
1977.
Q3: Are turbines manufactured before October 3, 1977, and purchased
by Alyeska after that date from another owner who bought them before
that date, subject to subpart GG even if they may not have been placed
into operation by the previous owner before October 3, 1997?
A3: In the case of stationary gas turbines that are mass-produced
and purchased in completed form, EPA considers the manufacturer as the
original owner or operator. The turbines are not subject to subpart GG
provided that they were not modified or reconstructed after October 3,
1977.
Q4: Do the requirements of subparts A and GG apply only to a
turbine, as the ``affected facility,'' so that a turbine that is
subject to these subparts is operated as a GG turbine no matter where
it is operated on the TAPS?
A4: Under subparts A and GG, the turbine is the affected facility
and the requirements of these subparts follow a turbine constructed,
modified, or reconstructed after October 3, 1977, regardless of where
the turbine is relocated. The affected facility is the stationary gas
turbine and does not include the equipment that is powered by the
turbine (such as a generator or pump).
Q5: Do turbines manufactured before October 3, 1977, become subject
to subpart GG if they are treated as a pool of identical turbines and
moved from location to location between TAPS pump stations to allow for
the maintenance of turbines?
A5: Assuming that the maintenance does not result in a modification
or reconstruction, and that the turbines are not otherwise modified or
reconstructed, relocation of the turbine as part of a pool of identical
turbines would not subject the turbine to subpart GG.
Q6: Does a turbine that is not subject to subpart GG (because it
was not constructed, modified, or reconstructed after October 3, 1977)
become subject to subpart GG if it is rotated into a location to
replace a turbine that is subject to this subpart?
A6: No. A turbine that was not constructed, modified, or
reconstructed after October 3, 1977, does not become subject to subpart
GG simply because it is rotated into a location to replace a turbine
that is subject to this subpart.

Q: Will EPA approve custom fuel monitoring for nitrogen and sulfur
for a planned natural gas-fueled, turbine-driven pipeline compressor
subject to subpart GG?
A: Yes, EPA approves a custom monitoring schedule, per 40 CFR
60.334(b)(2), that allows for no monitoring of fuel nitrogen as long as
the affected source is supplied with solely pipeline quality natural
gas. In addition, EPA approves a custom fuel monitoring schedule for
sulfur. The
[[Page 7379]]
schedule requires monitoring twice monthly for the first six months,
and, if the affected source has test results less than 50 percent of
the sulfur limit, then twice a year, during the first and third
calendar quarters, as long as the affected source maintains compliance.

Q: A refinery has process area reactors and distillation columns
whose only gas streams are combusted in the refinery's fuel gas system.
These gas streams are exempt from any compliance monitoring
requirements under 40 CFR part 63, subpart G. Does 40 CFR 63.110(d)(10)
also exempt those gas streams from the requirements of NSPS subparts
NNN and RRR?
A: No. Section 63.110(d)(10) does not exempt the gas streams from
meeting the requirements of NSPS subparts NNN and RRR.
Abstract for [0200083]:
Q: Are electric arc furnaces in steel forging plants regulated by
subparts AA and AAa?
A: If a plant manufactures a product that comes from a mold and
that product, as it comes out from the mold, is modified by rolling,
forging, hot or cold working to alter its shape, the furnaces are
regulated.
Abstract for [0200084]:
Q. Is outdated pharmaceutical waste considered an industrial waste
that would make an incinerator a Commercial and Industrial Solid Waste
Incineration (CISWI) Unit?
A. No. As the waste in question is from a warehouse, it is a
municipal waste and, as a result, the unit is not subject to the CISWI
regulations.
Abstract for [0200085]:
Q: For purposes of NSPS subpart H, what portions of a facility
containing both sulfuric acid and liquid sulfur dioxide operations
constitute a sulfuric acid plant?
A: On the basis of the information provided on this particular
facility, only the sulfuric acid operations constitute a sulfuric acid
plant under subpart H.
Abstract for [0200086]:
Q: A facility mines and crushes argillite and then fires it in
kilns to produce lightweight aggregate. Are the lightweight aggregate
product crushers/grinders, conveyors, screeners, and storage bins which
follow the kilns subject to subpart OOO?
A: Yes. Even if no crushing or grinding takes place after the
kilns, the subsequent material handling equipment would still be
subject to subpart OOO as it is part of the nonmetallic mineral
production line in which crushing and grinding of raw material takes
place. The lightweight aggregate product is a nonmetallic mineral. The
facility should also consider the potential applicability of subpart
UUU to specific operations at the facility.
Abstract for [0200087]:
Q: Should facilities subject to NSPS subpart OOO submit routine
reports to the appropriate agency with delegated authority for
implementing the regulation, instead of EPA Region 4?
A: Yes. Facilities subject to NSPS subpart OOO only need to submit
routine reports to the appropriate agency with delegated authority for
implementing the regulation. There is no need to submit the reports to
EPA Region 4.
Abstract for [0200088]:
Q: A facility crushes and grinds clay and then deposits it onto a
storage pile. The clay is later removed from the storage pile and
transferred by a conveyor to brick manufacturing equipment in a making
