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 and National 
Emission Standards for Hazardous Air Pollutants

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability.

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

SUMMARY: This notice announces the availability of applicability 
determinations, alternative monitoring decisions, and regulatory 
interpretations that EPA has made under the New Source Performance 
Standards (NSPS) (40 CFR part 60), and the National Emission Standards 
for Hazardous Air Pollutants (NESHAP) (40 CFR parts 61 and 63).

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 ADI at: http://cfpub.epa.gov/adi. 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: [email protected]. 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. The NSPS and NESHAP also 
allow sources to seek permission to use monitoring or recordkeeping 
which are 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. Further, 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 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. 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 30 of such documents added to 
the ADI on January 22, 2002. The subject, author, recipient, and date 
(header) of each letter and memorandum is 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 at: http://cfpub.epa.gov/adi.

Summary of Headers and Abstracts

    The following table identifies the database control number for each 
document posted on the ADI database system on January 22, 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

Abstract for [M020001]

    Q1: Will EPA consider a facility that does not have a permit 
limiting its potential to emit below the major source threshold before 
the first compliance date of the dry cleaner MACT, Subpart M, an area 
source if the facility can demonstrate that it maintained its 
consumption of perc below the major source threshold in the dry cleaner 
MACT?
    A1: Yes. EPA intended that the dry cleaner MACT provide the method 
for identifying major sources under both the MACT program and Title V. 
However, the facility must reconcile reported VOC emissions that 
indicate perc consumption almost double the threshold.
    Q2: For a new facility subject to the MACT, Subpart M, does the 
one-time initial fill count in determining whether the facility is a 
major source?
    A2: No. The initial fill does not indicate perc emissions, since 
perc has been neither consumed nor emitted.

    Q. Under MACT standard, Subpart R, what is the required monitored 
operating parameter for the John Zink enclosed flares?
    A: The MACT standard, Subpart R, requires that thermal oxidation 
systems (e.g., John Zink enclosed flares) monitor temperature for 
continuous compliance monitoring.

Abstract for [0100077]

    Q: A company with a natural gas-fired boiler proposes to record and 
maintain weekly records of fuel usage, instead of daily records as 
required by NSPS Subpart Dc, at 40 CFR 60.48c(g). Is this acceptable?
    A: Yes. If only natural gas or low sulfur fuel oils are used, 
compliance with NSPS Subpart Dc, can be adequately verified by keeping 
fuel usage records less frequently. Based on past determinations, 
records of fuel usage may be kept on a weekly basis, as proposed, or on 
a monthly basis as has been approved for other natural gas-fired 
facilities.

Abstract for [0100078]

    Q: A company subject to NSPS Subpart VV, has proposed to conduct 
quarterly visual inspections of equipment in ethylene glycol vapor 
service, instead of using Method 21. Since ethylene glycol has a 
boiling point of approximately 197 degrees centigrade, any vapor 
escaping from process equipment would quickly condense and form a 
liquid, making detection by Method 21 less accurate and reliable. Is 
the use of visual inspections acceptable?
    A: Yes. The proposed alternative monitoring is acceptable as a 
substitute for Method 21.

Abstract for [0100079]

    Q: Is a blast furnace slag crushing/grinding operation subject to 
NSPS Subpart OOO?
    A: No. Because slag is not a nonmetallic mineral, the crushing and 
grinding of slag is not regulated by NSPS Subpart OOO.

Abstract for [0100080]

    Q: A boiler derate is proposed for a unit subject to NSPS Subpart 
Db which will include the replacement of an existing burner with a new 
burner rated at 95 mm btu/hr. Is the proposed derate acceptable?
    A: Yes. The proposed derate is consistent with criteria used in 
past boiler derates.

Abstract for [0100081]

    Q: Does the design capacity exemption provided in NSPS Subparts VV 
and NNN apply to a process unit at a plant which will produce a product 
which will contain 50 percent hydrogen cyanide and 50 percent methanol? 
Hydrogen cyanide will be produced at the facility, but methanol will 
not be produced. The design capacity for hydrogen cyanide is less than 
one gigagram per year.

[[Page 14938]]

    A: Yes. The design capacity for the process unit will be less than 
the threshold of one gigagram per year. The applicable recordkeeping 
and reporting requirements of NSPS Subparts VV and NNN will need to be 
met.

Abstract for [0100082]

    Q: A derate method is proposed which will limit the capacity of a 
boiler by reducing the air volume into the boiler. Will the proposed 
method be acceptable to comply with NSPS Subpart Dc?
    A: Yes. The proposed derate is consistent with criteria used in 
past boiler derates.

Abstract for [0100083]

    Q: Are ethanol manufacturing facilities exempt from the 
requirements of NSPS Subparts RRR and NNN?
    A: EPA has previously determined that ethanol manufacturing 
facilities may be exempted from NSPS Subparts RRR and NNN on a case-by-
case basis. The ethanol facility in question here uses a biological 
process to ferment the converted starches in corn into ethanol. These 
Subparts did not envision unit operations for biological processes.

Abstract for [0100084]

    Q: Will EPA approve alternative monitoring and waive the 
requirement for performance testing for boilers and process heaters 
that are fired with fuel gas containing a vent stream from a facility 
subject to NSPS Subpart NNN?
    A: Yes. EPA will approve the provisions of NSPS Subpart RRR as 
alternative monitoring to the provisions of NSPS Subpart NNN and waive 
the requirement for performance testing for boilers and process heaters 
that are fired with fuel gas containing a vent stream from a facility 
subject to NSPS Subpart NNN.

Abstract for [0100085]

    Q1: Will EPA exempt a new stationary gas turbine facility subject 
to NSPS Subpart GG from daily nitrogen testing?
    A1: Yes. Nitrogen monitoring shall be waived for pipeline quality 
natural gas, as there is no fuel-bound nitrogen and the free nitrogen 
does not contribute appreciably to NOX emissions.
    Q2: Will EPA approve a custom fuel monitoring schedule for a 
facility subject to NSPS Subpart GG?
    A2: Yes. EPA will approve the custom fuel monitoring schedule 
according to an August 14, 1987, national policy which allows the EPA 
Regional offices to approve NSPS Subpart GG custom fuel monitoring 
schedules on a case-by-case basis.
    Q3: Will EPA approve an alternative test method under NSPS Subpart 
GG?
    A3: Yes. In accordance with an April 26, 1999, memorandum from 
EPA's Office of Air Quality Planning and Standards, ``length of stain'' 
detector tubes will be allowed in cases where fuel gas sulfur content 
is well below the standard level.

Abstract for [0100086]

    Q: Will EPA grant a source subject to NSPS Subpart GG, a waiver to 
Reference Method 20 to allow use of a single multi-hole probe in lieu 
of oxygen traverses prior to initiating performance tests?
    A: Yes. EPA grants the waiver on the basis that information 
provided indicates that the oxygen concentrations have been uniform 
within a variation of less than five percent across the two turbine 
stacks. Also, verbal information indicated that the multi-hole probe 
flow rate test showed that the sample flow rate through each hole is 
within plus or minus ten percent of the average through the eight holes 
at the design flow rate for the probe.

Abstract for [0100087]

    Q: Under NSPS Subpart GG, will EPA approve an alternative test 
method for two gas turbines whose stacks have four sampling ports on 
one side only?
    A: Yes. EPA approves the use of a nine-hole probe in the existing 
four ports to accomplish a four by nine sample point matrix instead of 
the required six by six matrix to determine the one of four ports with 
the lowest oxygen. EPA will also allow the use of a single multi-hole 
sample probe installed through the port which exhibits the lowest 
average diluent (oxygen) concentration for the oxygen traverse and the 
performance tests.

Abstract for [0100099]

    Q: Under NSPS Subpart GG, will EPA approve a request to eliminate 
submission of sulfur monitoring data and allow monitoring of sulfur 
level on a semi-annual basis?
    A: Yes. EPA will approve the request. Based on sulfur analyses 
submitted it appears that the gas used consistently meets the 
regulatory definition for natural gas. Although it does not appear to 
be pipeline natural gas, it is very low in sulfur and much cleaner than 
the sulfur standard of 0.8 percent by weight. The semi-annual 
monitoring results must be retained by the facility's owner.

    Q: Will EPA approve a custom fuel monitoring schedule for a 
facility subject to NSPS Subpart GG?
    A: Yes. EPA will approve the custom fuel monitoring schedule 
according to an August 14, 1987, national policy which allows the EPA 
Regional offices to approve NSPS Subpart GG custom fuel monitoring 
schedules on a case-by-case basis.

Abstract for [0100101]

    Q1: Under NSPS Subpart GG, will EPA approve a request to waive the 
requirement to monitor nitrogen content and sulfur content of natural 
gas on a semi-annual basis?
    A1: Yes. EPA will waive nitrogen monitoring for pipeline quality 
natural gas, as there is no fuel-bound nitrogen and the free nitrogen 
does not contribute appreciably to NOX emissions. A record 
shall be maintained documenting a constant supplier or source of fuel. 
If there is a change in either, the facility must notify EPA.
    Q2: Under NSPS Subpart GG, will EPA approve a request to test for 
fuel sulfur content using the method specified in 40 CFR part 75, 
appendix D, section 2.3?
    A2: Yes. EPA approves the request to use the monitoring 
requirements for sulfur in 40 CFR part 75. This alternative monitoring 
method may only be used when pipeline natural gas is the only fuel 
being burned.
    Q3: Under NSPS Subpart GG, will EPA approve a request to determine 
fuel consumption at full load only as an alternative to testing at four 
loads where the turbines are not expected to operate below 90%?
    A3: Yes. EPA approves the request to use a single load test at full 
load. However, should the operation fall below 90% of maximum load, 
then testing at four loads would be required within 60 days of the new 
operating level.
