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 Sec. Sec.  60.5 and 61.06. 
Although the NESHAP part 63 regulations [which include Maximum 
Achievable Control Technology (MACT) standards] and Sec.  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 Sec.  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. 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, 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 32 such documents added to 
the ADI on October 30, 2013. 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 through the OECA Web site at: www.epa.gov/compliance/monitoring/programs/caa/adi.html.

Summary of Headers and Abstracts

    The following table identifies the database control number for each 
document posted on the ADI database system on October 30, 2013; 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 Sec.  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.

    Q: Will EPA consider as force majeure certain contract disputes 
between a company and its contractor over production testing and plant 
operation at a facility that prevented stack tests from being conducted 
before the compliance deadline under 40 CFR part 60, subparts OOO and 
UUU, at the Cadre Material Products crusher and calciner facility in 
Voca, Texas?
    A: No. EPA disagreed that the events described in the request 
letter met the criteria of force majeure under 40 CFR 60.8(a), because 
the contract dispute was not beyond the company's ability to control. 
EPA disapproved the request for an eight week extension to conduct 
required performance testing and submit the necessary reports; however, 
EPA granted a one-week extension for adverse weather conditions that 
occurred and did meet force majeure criteria.

    Q1: Does 40 CFR part 60, subparts A and KKK apply to a backup vapor 
recovery unit (BU-VRU) compressor at the Marathon Petroleum (Marathon) 
Indian Basin Gas Plant (IBGP) near Carlsbad, New Mexico?
    A1: Yes. EPA determined that the BU-VRU compressor unit is 
considered to be in VOC service. Even though the compressor is 
associated with pollution control equipment, the pollution control 
exemption of 40 CFR 60.14(e) of the General Provisions cannot apply 
because of a direct conflict with the applicability provisions of NSPS 
subpart KKK. The provisions of 40 CFR 60.630 supersede any exemptions 
in 40 CFR 60.14.
    Q2: Does 40 CFR part 60, subparts A and Kb apply to two stabilized 
condensate storage tanks at the Marathon IBGP near Carlsbad, New 
Mexico?
    A2: Yes. EPA determined that the two storage tanks are located 
after the point of custody transfer since these are located in the 
natural gas processing plant, which is upstream of the IBGP. Therefore, 
both tanks are subject to the requirements of NSPS subpart Kb because 
the custody transfer exemption of 40 CFR Sec.  60.110b(d)(4) does not 
apply.

    Q: Does EPA approve ExxonMobil's Alternative Monitoring Plan (AMP) 
under 40 CFR 60.13(i)(3) and 63.8(4)(i) for monitoring a wet gas 
scrubber (WGS) on refinery Fluid Catalytic Cracking Unit (FCCU) No. 2, 
in lieu of a Continuous Opacity Monitoring System (COMS), to 
demonstrate compliance with the opacity limits under 40 CFR 
60.102(a)(2) and parameter monitoring requirements of 40 CFR Sec.  
63.1564(b)(1) at ExxonMobil's Baytown, Texas refinery (ExxonMobil)?
    A: Yes. EPA granted final approval of ExxonMobil's AMP based on its 
approval of the two scrubber operating parameter limits (OPLs) 
established under performance testing at representative operating 
conditions for the FCCU and each WGS. The establishment of the two OPLs 
and their approval by EPA were conditions in a prior approval. 
Previously, EPA had conditionally approved ExxonMobil's AMP request 
since moisture in the FCCU exhaust from the WGS interfered with the 
ability of the COMS to take accurate readings, due to excessive water 
at the point of measurement, and flow meters were not reliable for 
measuring WGS scrubber liquid recirculation rates. In the response 
letter, EPA also clarified that ongoing compliance demonstration for 
each approved OPL is to be based on a three hour rolling average 
period.

    Q: Does EPA approve ConocoPhillips' Alternative Monitoring Plan 
(AMP) under 40 CFR 60.13(i)(3) for monitoring a wet gas scrubber (WGS) 
on refinery Fluid Catalytic Cracking Unit (FCCU) No. 4, in lieu of a 
Continuous Opacity Monitoring System (COMS), to demonstrate compliance 
with the opacity limit under 40 CFR 60.102(a)(2) at ConocoPhillips' 
Ponca City, Oklahoma refinery?
    A: Yes. EPA granted final approval of ConocoPhillips' AMP request 
established under performance testing at representative operating 
conditions for the FCCU and each WGS. The establishment of the two OPLs 
and their approval by EPA were conditions in a prior approval. 
Previously, EPA had conditionally approved ConocoPhillips' AMP request 
because moisture in the FCCU exhaust from the WGS interfered with the 
ability of the COMS to take accurate readings, due to excessive water 
at the point of measurement. As described in the response letter, EPA 
also required continued periodic testing to confirm OPLs for ongoing 
compliance demonstration beyond the termination of the existing Consent 
Decree.

    Q: Does EPA approve ConocoPhillips' Alternative Monitoring Plan 
(AMP) under 40 CFR 60.13(i)(3) for monitoring a wet gas scrubber (WGS) 
on refinery Fluid Catalytic Cracking Unit (FCCU) No. 5, in lieu of a 
Continuous Opacity Monitoring System (COMS), to demonstrate compliance 
with the opacity limit under 40 CFR 60.102(a)(2) at ConocoPhillips' 
Ponca City, Oklahoma refinery?
    A: Yes. EPA granted final approval to ConocoPhillips' AMP request 
established under performance testing at representative operating 
conditions for the FCCU and each WGS. The establishment of the OPLs and 
their approval by EPA were conditions in a prior approval. Previously, 
EPA had conditionally approved ConocoPhillips' AMP request since 
moisture in the FCCU exhaust from the WGS interfered with the ability

    Q: Will EPA approve Motiva's Alternative Monitoring Plan (AMP) 
under 40 CFR 60.13(i)(3) for monitoring wet gas scrubbers (WGS) on a 
refinery Fluid Catalytic Cracking Unit (FCCU), in lieu of a Continuous 
Opacity Monitoring System (COMS), to demonstrate compliance with the 
opacity limit under 40 CFR 60.102(a)(2) at Motiva's Convent, Louisiana 
refinery?
    A: Yes. EPA conditionally approves Motiva's AMP since moisture in 
the FCCU exhaust from the WGS interfered with the ability of the COMS 
to take accurate readings due to excessive water at the point of 
measurement. The conditions for approval require that Motiva establish 
three Operating Parameter Limits (OPLs) under performance testing at 
representative operating conditions for the FCCU and each WGS, whereby 
worst-case emissions are anticipated. EPA identified the three OPLs to 
ensure that the WGSs function as intended and emissions from the FCCU 
will meet the regulatory requirements for particulate matter, sulfur 
dioxide and opacity.

    Q: Does EPA approve an exemption in lieu of a previously submitted 
Alternative Monitoring Plan (AMP) request for combusting a vent stream 
from an alkylation unit in a dedicated process flare as an inherently 
low-sulfur stream under 40 CFR part 60 subpart Ja, at Valero Refining's 
Ardmore, Oklahoma refinery?
    A: Yes. EPA determined that a monitoring exemption is appropriate 
for the Alkylation Unit vent stream, and voided the AMP request. Based 
upon review of the information provided, EPA agreed that the dedicated 
process flare is exempt from the monitoring requirements of 40 CFR 
60.105a(g) because the vent stream combusted in the flare is inherently 
low in sulfur because it is produced in a process unit intolerant to 
sulfur contamination, and thus, meets the conditions and exemption 
criteria of sulfur content below 5 parts per million in 40 CFR 
60.107a(a)(3)(iii). The effective date of the exemption is the 
effective date of the reissued final rule and lift of stay, November 
13, 2012. EPA also clarified that the exemption determination should be 
referenced and attached to the facility's new source review and Title V 
permit for federal enforceability.

    Q: Does EPA approve Marathon Petroleum's (Marathon) Alternative 
Monitoring Plan (AMP) under 40 CFR 60.13(i)(3) for monitoring a wet gas 
scrubber (WGS) on a refinery Fluid Catalytic Cracking Unit (FCCU), in 
lieu of a Continuous Opacity Monitoring System (COMS), to demonstrate 
compliance with the opacity limit under 40 CFR 60.102(a)(2) at 
Marathon's Texas City, Texas refinery?
    A: Yes. EPA granted final approval of Marathon's AMP request based 
on the approval of the three scrubber operating parameter limits (OPLs) 
established under performance testing at representative operating 
conditions for the FCCU and each WGS. The establishment of the OPLs and 
their approval by EPA were conditions in a prior approval. Previously, 
EPA had conditionally approved Marathon's AMP request since moisture in 
the FCCU exhaust from the WGS interfered with the ability of the COMS 
to take accurate readings due to excessive water at the point of 
measurement. In the response letter, EPA also clarified that compliance 
demonstration for each OPL was to be based on a three hour rolling 
average period, and required continued periodic testing to confirm OPLs 
for ongoing compliance demonstration.

    Q: Does EPA approve Motiva's Alternative Monitoring Plan (AMP) 
under 40 CFR 60.13(i)(3) for monitoring a hydrogen sulfide 
(H2S) vent stream combusted in a crude charge heater, in 
lieu of a Continuous Emissions Monitoring System (CEMS), to demonstrate 
compliance with the sulfur dioxide (H2S) monitoring 
requirements of 40 CFR 60.105(a)(3) and (4) under NSPS subpart J, at 
Motiva's Convent, Louisiana refinery?
    A: No. EPA determined that Motiva's AMP request is not acceptable 
because it has not submitted sufficient information to justify it. EPA 
requires that at least two critical independent Operating Limit 
Parameters (OPLs) be proposed for the caustic pre-wash tower to be able 
to obtain EPA's approval for using a daily ``doctor test'' (ASTM Method 
D4952-09) to monitor total sulfur and sulfides in the tower outlet 
effluent, in lieu of installing a H2S CEMS. Therefore, the 
requirement to install a CEMS for monitoring H2S in the vent 
stream combusted in the Crude Charge Heater under 40 CFR 60.105(a)(4) 
shall continue to apply.

an inherently low-sulfur stream under 40 CFR part 60 subpart J, at the 
ExxonMobil's Beaumont, Texas refinery?
    A: Yes. EPA approves the monitoring exemption for the catalytic 
hydrodesulfurization vent stream, and voided ExxonMobil's AMP request 
based on the process operating parameters and monitoring data submitted 
by the company and in light of changes made to Subpart J on June 24, 
2008 (73 FR 35866). The vent stream combusted in the heater meets the 
conditions and exemption criteria of 40 CFR 60.105(b)(1)(i)-(v), and 
therefore has been demonstrated to be inherently low in sulfur since it 
meets the conditions and exemption criteria of sulfur content below 5 
parts per million in 40 CFR 60.105(a)(4)(iv)(C). EPA agreed that the 
process heater is exempt from monitoring requirements of 40 CFR 
60.105(a)(3) and (4). If refinery operations change from 
representations made for this exemption determination, then ExxonMobil 
must document the change(s) and follow the appropriate steps outlined 
in 40 CFR 60.105(b)(3)(i)-(iii).

    Q: Does EPA approve an exemption in lieu of an Alternative 
Monitoring Plan (AMP) for combusting the combined vent stream from a 
catalytic platinum reformer unit (PtR-4) in two heaters or a low 
pressure flare as an inherently low-sulfur stream under 40 CFR part 60 
subpart J, at the ExxonMobil Beaumont, Texas refinery?
    A: Yes. EPA determined that a monitoring exemption is appropriate 
for the combined vent stream, and voided the AMP request based on the 
process operating parameters and monitoring data submitted by the 
company and in light of changes made to Subpart J on June 24, 2008 (73 
FR 35866). EPA agreed that the heaters and flare that burn the vent 
stream are exempt from monitoring requirements of 40 CFR 60.105(a)(3) 
and (4). The combined vent stream combusted is inherently low in sulfur 
because it is produced in a process unit intolerant to sulfur 
contamination, and thus, meets the conditions and exemption criteria of 
sulfur content below 5 parts per million in 40 CFR 60.105(a)(4)(iv)(C). 
If refinery operations change such that the sulfur content of the off-
gas vent stream changes from representations made for this exemption 
determination, then ExxonMobil must document the change(s) and follow 
the appropriate steps outlined in 40 CFR 60.105(b)(3)(i)-(iii).

    Q: Does EPA approve an Alternative Monitoring Plan (AMP) for vent 
stream flow monitoring for a distillation column and associated flare 
to implement NSPS subpart RRR testing, monitoring, and recordkeeping 
provisions in lieu of complying with corresponding provisions of NSPS 
subpart NNN, with the exception of small vent and drain valves utilized 
for maintenance events, for the Advanced Aromatics facility in Baytown, 
Texas?
    A: Yes. EPA approves Advanced Aromatics' AMP request to implement 
NSPS subpart RRR for testing, monitoring, and recordkeeping provisions 
in lieu of complying with corresponding provisions of NSPS subpart NNN 
for a distillation column vent stream routed to a flare without any by-
pass lines. To ensure that affected vent streams are routed to 
appropriate control devices, Advanced Aromatics is required to maintain 
a schematic diagram of the affected vent streams, collection system(s), 
fuel systems, control devices, and bypass systems as part of the 
initial report submitted in accordance with 40 CFR 60.705(b). EPA noted 
that small vent and drain valves utilized for maintenance events are 
not exempt under NSPS subpart NNN or subpart RRR. Therefore, flow must 
be monitored during maintenance events at these locations in accordance 
with NSPS subpart RRR, because such components act as bypass valves 
during such events (i.e., flow is diverted away from the control 
device).

    Q: The Arkansas Department of Environmental Quality requests 
guidance from EPA on whether prescription drugs collected by the police 
department during community voluntary take back programs in Arkansas 
meet the definition of confiscated contraband under 40 CFR 60.2887(p), 
in order to claim an exclusion from NSPS subpart EEEE requirements for 
other solid waste incinerators (OSWI)?
    A: No. EPA does not consider prescription drugs collected from 
households during a community take back program to be illegal or 
prohibited drugs; therefore, they are not ``contraband.'' As described 
in the preamble to the OSWI final rule (69 FR 71483), such drugs are 
clearly not confiscated, since they are voluntarily collected.

    Q: Does EPA approve exemptions in lieu of Alternative Monitoring 
Plans (AMP) for combusting multiple vent streams from a coker, 
disulfide separator, and reformer in various combustion devices as 
inherently low-sulfur streams under 40 CFR part 60 subpart J, at the 
Valero Refining Texas City, Texas refinery?
    A: Yes. EPA approves a monitoring exemption for the vent streams, 
and voided the original AMP request based on review of the information 
provided by the company and in light of changes made to Subpart J on 
June 24, 2008 (73 FR 35866). EPA agreed that the combustion devices are 
exempt from monitoring requirements of 40 CFR 60.105(a)(3) and (4). The 
two vent streams combusted are inherently low in sulfur because they 
are produced in a process unit intolerant to sulfur contamination, and 
thus, meet the conditions and exemption criteria of sulfur content of 
below 5 parts per million in 40 CFR 60.105(a)(4)(iv)(C). If

[[Page 68437]]

refinery operations cause a change in an exempt stream status, then 
Valero must document the change and determine if the stream remains 
exempt.

    Q: Does EPA approve an alternative monitoring plan (AMP) to use a 
lower alternate span value for a nitrogen oxide (NOX) 
continuous emissions monitoring system (CEMS) than what is required in 
40 CFR 60.48b(e)(2) on a boiler required to meet more stringent 
NOX emission limit under Best Available Control Technology 
(BACT) and subject to NSPS subpart Db, at ConocoPhillips' Westlake, 
Louisiana facility?
    A: Yes. EPA approves ConocoPhilip's AMP to lower the Boiler 
NOX CEMS span setting from 500 ppm to 100 ppm for the 
existing facility operations. The use of BACT may lower stack gas 
concentrations such that the span value of 500 ppm for NOX 
CEMS specified by 40 CFR 60.48b(e)(2) may be too high to ensure 
accurate and reliable reporting of compliance with a more stringent 
NOX emission limit. The proposed lower span setting should 
ensure accuracy in measuring actual NOX concentrations in 
the boiler stack gases so that compliance can be demonstrated with 
adequate confidence levels.

    Q: Does EPA approve ConocoPhillips' Alternative Monitoring Plan 
(AMP) under 40 CFR 60.13(i)(3) for monitoring a wet gas scrubber (WGS) 
on a refinery Fluid Catalytic Cracking Unit (FCCU), in lieu of a 
Continuous Opacity Monitoring System (COMS), to demonstrate compliance 
with the opacity limit under 40 CFR 60.102(a)(2) at ConocoPhillips' 
Sweeny, Texas refinery?
    A: Yes. EPA granted final approval of ConocoPhillips' AMP request 
based on approval of the three scrubber operating parameter limits 
(OPLs) CHD No. 1 established under performance testing at 
representative operating conditions. The establishment of the three 
OPLs and their approval by EPA were conditions in a prior approval. 
Previously, EPA had conditionally approved the AMP since moisture in 
the FCCU exhaust from the WGS interfered with the ability of the COMS 
to take accurate readings, due to excessive water at the point of 
measurement.

    Q: Does EPA approve an Alternative Monitoring Plan (AMP) request 
and a performance test waiver for two ethylene distillation columns 
vent streams being introduced with the primary fuel into associated 
boilers and process heaters without any bypass lines, in accordance 
with 40 CFR 60.8(b), and as provided by 40 CFR 60.704(b)(5), to 
implement NSPS subpart RRR testing, monitoring, and recordkeeping 
provisions in lieu of complying with corresponding provisions of NSPS 
subpart NNN, at the Chevron Phillips facility in Port Arthur, Texas?
    A: Yes. EPA approves Chevron Phillips' AMP request to implement the 
NSPS subpart RRR for testing, monitoring, and recordkeeping provisions, 
in lieu of complying with corresponding provisions of NSPS subpart NNN. 
To ensure that affected vent streams are routed to the appropriate 
control devices, Chevron Phillips facility is required to maintain a 
schematic diagram of the affected vent streams, collection system(s), 
fuel systems, and control devices as part of the initial report 
submitted in accordance with 40 CFR 60.705(b).

    Q: Does EPA approve an exemption in lieu of an Alternative 
Monitoring Plan (AMP) for combusting three vent streams from a 
catalytic hydrodesulfurization unit as inherently low-sulfur streams 
under 40 CFR part 60 subpart J, at the Citgo Petroleum Corpus Christi, 
Texas East refinery (Citgo)?
    A: Yes. EPA determined that a monitoring exemption is appropriate 
for the specified Hydrar vent streams, and voided the original AMP 
request in light of the changes of the revised rule dated June 24, 
2008. Based on a review of the information provided, EPA agreed that 
combustion devices which burn the streams are exempt from the 
monitoring requirements of 40 CFR 60.105(a)(3) and (4). The vent 
streams combusted are inherently low in sulfur because they are 
produced in a process unit intolerant to sulfur contamination, and 
thus, meet the conditions and exemption criteria of sulfur content 
below 5 parts per million in 40 CFR 60.105(a)(4)(iv)(C). If refinery 
operations cause a change in an exempt stream status, then Citgo must 
document the change and determine if the stream remains exempt. If it 
is determined that the streams are no longer exempt, continuous 
monitoring at each combustion device must begin within 15 days of the 
change, in accordance with 40 CFR 60.105(a)(4)(iv).

Monitoring Plan (AMP) for combusting a vent stream from a cumene 
depropanizer unit as an inherently low-sulfur stream under 40 CFR part 
60 subpart J, at the Citgo Petroleum Corpus Christi, Texas East 
refinery (Citgo)?
    A: Yes. EPA determined that a monitoring exemption is appropriate 
for the vent stream from a cumene depropanizer unit, and voided the 
original Citgo's AMP in the light of the changes of the revised rule 
dated June 24, 2008. Based on a review of the information provided, EPA 
agreed that combustion devices that burn the vent stream are exempt 
from monitoring requirements of 40 CFR 60.105(a)(3) and (4). The vent 
stream combusted is inherently low in sulfur because it is produced in 
a process unit intolerant to sulfur contamination, and thus, meets the 
exemption criteria of sulfur content below 5 parts per million in 40 
CFR 60.105(a)(4)(iv)(C). If refinery operations cause a change in an 
exempt stream status, then Citgo must document the change and determine 
if the stream remains exempt. If it is determined that the stream is no 
longer exempt, continuous monitoring at each combustion device must 
begin within 15 days of the change, in accordance with 40 CFR 
60.105(a)(4)(iv).

    Q: Does EPA approve an Alternative Monitoring Plan (AMP) under 40 
CFR 60.13(i)(3) for monitoring wet gas scrubbers (WGS) on a refinery 
Fluid Catalytic Cracking Unit (FCCU), in lieu of a Continuous Opacity 
Monitoring System (COMS), to demonstrate compliance with the opacity 
limit under 40 CFR 60.102(a)(2) at Citgo Petroleum's (Citgo) Lake 
Charles, Louisiana refinery?
    A: EPA conditionally approves Citgo's AMP request. The AMP approval 
is conditioned on Citgo conducting another performance test (PT) to 
properly evaluate under representative operating conditions and 
establish the three operating parameter limits (OPLs) for each WGS to 
ensure these scrubbers function as intended, and that the PT results 
indicate that emissions from the FCCU meet the particulate matter, 
sulfur dioxide and opacity standards.

    Q: Does EPA approve an exemption in lieu of an Alternative 
Monitoring Plan (AMP) for combusting a vent stream from a catalytic 
reformer unit in a flare as an inherently low-sulfur stream

[[Page 68438]]

under 40 CFR part 60 subpart J, at the ConocoPhillips Sweeny, Texas 
refinery?
    A: Yes. EPA determined that a monitoring exemption is appropriate 
for the catalytic reformer unit vent stream, and voided the original 
AMP in light of the changes made in the revised rule dated June 24, 
2008. Based on a review of the information provided, EPA agreed that 
the flare is exempt from the monitoring requirements of 40 CFR 
60.105(a)(3) and (4). The vent stream combusted in the flare is 
inherently low in sulfur because it is produced in a process unit 
intolerant to sulfur contamination, and thus, meets the conditions and 
exemption criteria of sulfur content below 5 parts per million in 40 
CFR 60.105(a)(4)(iv)(C). If other sulfur/sulfide bearing streams not 
from catalytic reformers enter the stripper and become part of the 
waste fuel gas stream, ConocoPhillips must apply for an AMP on the 
stripper, and propose at least three independent process parameters to 
ensure a low sulfur/sulfide stream going to the flare. EPA clarify that 
any significant increase in the sulfur/sulfide concentration detected 
in the stream would initiate continuous monitoring under 40 CFR 60.1 
05(a)(3) or (4).

    Q: Does EPA approve a waiver of the requirement under NSPS subpart 
NNN at 40 CFR 60.663(b)(2), and to implement the alternative monitoring 
requirements of NSPS subpart RRR at 40 CFR 60.703(b)(2)(ii) instead, at 
the ConocoPhillips East Vacuum Liquid Recovery/CO2 Plant in Lea County, 
New Mexico?
    A: Yes. EPA approves ConocoPhillips' AMP request for a waiver of 
the monitoring requirements under 40 CFR 60.663(b)(2) to implement the 
monitoring requirements of 40 CFR 60.703(b)(2)(ii) instead, which will 
allow for the use of car seals on closed bypass valves in lieu of flow 
indicators. To ensure that affected vent streams are routed to 
appropriate control devices, ConocoPhillips is required to maintain a 
schematic diagram of the affected vent streams, collection system(s), 
fuel systems, control devices, and bypass systems as part of the 
initial report submitted in accordance with 40 CFR 60.705(b).

    Q: Are marine vessel loading vapors that are inherently low in 
sulfur, collected by a Marine Vapor Recovery (MVR) system and routed to 
an air-assisted marine flare vapor combustor, at the ExxonMobil 
Beaumont, Texas refinery, subject to MACT subpart Y requirements under 
40 CFR 63.562, also subject to New Source Performance Standards (NSPS) 
for Refineries, part 60, subpart J?
    A: No. EPA determines that if the vent stream is collected to 
comply with the provisions for marine tank vessel loading under 40 CFR 
63.562 or 40 CFR 63.651, it does not meet the definition of a fuel gas, 
as defined at 40 CFR 60.101(d). EPA evaluated ExxonMobil's request in 
light of changes made to NSPS subpart J on June 24, 2008, which 
modified the definition of fuel gas to specifically exclude vapors 
collected and combusted to comply with provisions of 40 CFR 63.562 or 
40 CFR 63.651.

continuous emissions monitoring system (CEMS) on sulfur recovery units 
(SRU) subject to NSPS subpart J at the Flint Hills Resources (FHR) East 
and West Refineries in Corpus Christi, Texas?
    A: Yes. EPA approves the AMP request for the proposed lower span 
setting of 10 percent for the specified CEMS since it satisfied 
criteria established in Performance Specification 2 of subpart 60, 
Appendix B. Based on the information provided in your AMP request, the 
lower span setting on specified CEMS should ensure accuracy in 
measuring actual pollutant concentrations in stack gases so that 
compliance can be demonstrated with adequate confidence levels.

    Q: Does EPA approve a petition to use Operating Parameter Limits 
(OPLs) to limit emissions in lieu of using a wet scrubber for a dual 
chamber commercial other solid waste incinerator (OSWI) unit, which 
destroys contraband for U.S. Customs and other law enforcement 
agencies, under NSPS subpart FFFF, located at Kippur Corporation's 
(Kippur) El Paso, Texas facility?
    A: No. EPA denies Kippur's petition due to a lack of information 
pertaining to the recent modification made to increase the design 
capacity of the OWSI unit, as well as a lack of information pertaining 
to both the proper characterization of material fired to the OSWI Unit 
and the proper operation, performance testing established under 
representative operating conditions, and subsequent monitoring of the 
OSWI unit proposed OPLs to demonstrate compliance with the rule. As 
described in the EPA response letter, this information is needed to be 
able to evaluate the petition under the appropriate rule that applies 
to the modified OSWI unit. If a modification occurred, then according 
to 40 CFR 60.2992, the OSWI unit becomes subject to 40 CFR part 60 
subpart EEEE and 40 CFR part 60 subpart FFFF no longer applies.

    Q1: The Oklahoma Department of Environmental Quality (ODEQ) 
requests guidance from EPA on whether engines with: (1) A maximum 
engine power equal to or greater than 75 KW (100 HP), except gasoline 
and rich burn engines that use liquid petroleum gas, which were 
manufactured between 06/12/2006 and 07/01/2007, and for which the owner 
or operator commenced construction after 06/12/2006; and (2) lean-
burning maximum engine power equal to or greater than 500 HP but less 
than 1,350 HP, manufactured between 06/12/2006 and 01/01/2008, and for 
which the owner or operator commenced construction after 06/12/2006; 
are subject to requirements of 40 CFR part 63 subpart ZZZZ for 
reciprocating internal combustion engines (RICE MACT) and 40 CFR part 
60 subpart JJJJ for stationary spark ignition internal combustion 
engines (SSIICE)?
    A1: No. EPA concurs with ODEQ that the specified engines do not 
meet the criteria of 40 CFR 60.4230(a), and consequently have no 
applicable requirements under the SSIICE NSPS or the RICE MACT rules.
    Q2: What are the streamlined compliance requirements for various 
categories of engines in relation to the SSIICE NSPS or the RICE MACT?
    A2: EPA notes that if an engine specifically identified in 40 CFR 
63.6590(c) is not subject to any requirements in the NSPS SSIICE, then 
no further action is necessary for the specified engine under the RICE 
MACT. However, all other engines must meet additional requirements if 
so delineated in the RICE MACT.
    Q3: What are the key factors in determining whether an owner/
operator has any additional requirements to meet under the RICE MACT 
when the engine is not subject to NSPS SSIICE?
    A3: The key factors in determining if there are additional 
requirements to meet under the RICE MACT, when the engine is not 
subject to the SSIICE NSPS, are engine size and whether or

[[Page 68439]]

not the engine is located at a major source or area source.

    Q: The Asbestos Institute request clarification from EPA on whether 
the use of foam meet the ``adequately wet'' standard, as stated in the 
Asbestos NESHAP, 40 CFR part 61, subpart M?
    A: EPA determines that as long as the foam is applied as a liquid 
and sufficiently mixes with or penetrates the asbestos-containing 
material and prevents visible emissions, the use of such foam is 
acceptable in meeting the adequately wet requirement under the Asbestos 
NEHSAP M. The response is limited to this question regarding foam as a 
wetting agent. It is the responsibility of the owner or operator to 
meet other asbestos emission control requirements (also known as ``work 
practice standards'') during the demolition or renovation operation, as 
described in the EPA response letter.

    Q1: Cantey Hanger LLP request a determination for a client on 
whether only removing a 1500 foot section of the asbestos-containing 
material (ACM)-wrapped pipeline in a pipeline renovation project, while 
leaving the remainder of the non-friable ACM-wrapped pipeline in the 
ground, transform the site into a waste disposal site under 40 CFR 
61.154 of 40 CFR part 61, subpart M (i.e., Asbestos NESHAP)?
    A1: No. The Asbestos NESHAP does not apply to undisturbed pipelines 
coated with ACM that remain in the ground following a renovation 
project, which is the described scenario in your request, as long as no 
asbestos-containing waste material is deposited in the recently 
renovated area. This is consistent with a previously EPA issued 
applicability determination, ADI Control Number A030001 dated March 6, 
2003.
    Q2: If no additional ACM is deposited at the site for a year, would 
the site become an inactive waste disposal site per 40 CFR 61.154(g)?
    A2: Yes. If the renovated area does not receive asbestos-containing 
waste material, the site is not subject to the active waste disposal 
regulation at 40 CFR 61.154, in general and 40 CFR 61.154(g), 
specifically. Therefore, the inactive waste disposal requirement at 40 
CFR 61.151 of the Asbestos NESHAP does not apply.

    Q: Does 40 CFR part 61, subpart M (i.e., Asbestos NESHAP) apply to 
encapsulating wall board with spray foam insulation if the surface of 
the wall board will not be disturbed?
    A: EPA is unable to comment on whether encapsulating wall board 
with spray foam insulation would be compliant with the Asbestos NESHAP 
based on the limited on site-specific information provided in the 
request. However, if the work you are contemplating does not involve 
wrecking or taking out load-bearing structures (demolition) or altering 
one or more facility components, including stripping or removing 
regulated asbestos-containing material (renovation), then the Asbestos 
NESHAP for demolition and renovation operations does not apply to the 
proposed action.

    Q: Does EPA approve Valero Refinery's (Valero) Alternative 
Monitoring Plan (AMP) for using a video camera to monitor a flare pilot 
flame in a control room and record the observation, in lieu of having 
an ultraviolet (UV) flame detector, as required by 40 CFR part 63 
subpart CC, at Valero's Three Rivers refinery in Texas?
    A: No. EPA does not approve Valero's AMP since it determined that 
the equivalence of using a video camera that must be monitored by 
operations personnel in lieu of a continuous recording thermocouple or 
equivalent device was not demonstrated under 40 CFR 60.18(1)(2). 40 CFR 
63.644(a)(2) requires that a device that continuously detects the 
presence of a pilot flame must be used when the controlling device is a 
flare. 40 CFR 63.11(b)(5) requires that the monitoring device must be a 
thermocouple or equivalent device. A thermocouple has a continuous 
recording mechanism that is not dependent on operation or monitoring by 
personnel.

    Q: Is the propane dehydrogenation (PDH) plant located at the Dow 
Chemical Company, Texas Operations (Dow) site subject to 40 CFR part 63 
subpart YY (MON NESHAP) or subpart FFFF (GMACT and Ethylene MACT)?
    A: EPA determines that Dow's process is subject to the MON NESHAP, 
as it did not meet the criteria of an ethylene production process as 
defined by the Ethylene MACT due to the natural gas liquid feed stream 
and process conditions including temperature.

    Q: Is the integrated biosolids management system (IBMS), which uses 
dried biosolids as a feedstock in the gasifier to produce syngas for 
heat energy to be transferred to the indirect sludge dryer, located at 
the MaxWest South Sanford Water Resources Center (MaxWest) in Sanford, 
Florida, subject to 40 CFR part 61 subpart E?
    A: EPA determines that Subpart E is applicable to sludge gasifier 
and integrated thermal oxidizer portions and not to the sludge dryer 
portion of MaxWest's IBMS system. 40 CFR part 61 subpart E does not 
apply to MaxWest's IBMS sludge dryer portion because it does not meet 
the definition of ``sludge'' dryer in 40 CFR part 61 subpart E since it 
being indirectly heated by thermal transfer fluid with no contact with 
combustion gases. 40 CFR part 61 subpart E applies to MaxWest's 
combination of the gasifier and thermal oxidizer as together they 
comprise a sewage sludge incinerator of a two-steps process, one that 
produces the gases through the heating of sewage sludge, and a follow 
up unit in which the gases are combusted and emissions vented to the 
atmosphere.
