RE: 40 CFR 63 Subpart GGGGG - Notification of Compliance Status Report
Chevron Products Company - Salt Lake Refinery
Dear Mr. Bird:
The Chevron Salt Lake Refinery hereby submits a Notification of Compliance Status (NOCS) report for
40 CFR 63 Subpart GGGGG (SR MACT) as required by $63.7950(e) and $63.9(hX2). Chevron is
regulated by two ApprovalOrders (DAQE-ANl0l190106-22, dated August24,2022 and DAQE-
ANl0l 190104-22, dated September 26,2022) and has not yet been issued a Title V permit.
40 CFR 63 Subpart GGGGG was updated via final rulemaking on December 20,2022 (herein referred
to as "final rule"). Previously, 40 CFR 63 Subpart GGGGG included various RCRA and CERCLA
exemptions such that if site remediation activities were performed for one of those purposes, they were
exempt from additional requirements within 40 CFR 63 Subpart GGGGG; those exemptions applied at
the refinery. Pursuant to the final rule, EPA removed the RCRA and CERCLA exemptions within the
regulation. Per $63.7883(gXl), the compliance date is June 24,2024.
The attached report provides information pursuant to 563.9(hX2XiXA) through (G).
For questions and additional information, please contact Lauren Vander Werff at [phone] or

Ihls NOCS is being made in accordance with $63.7950(e) and $63.9(h).
All affected sources at the Refinery were constructed before May 13,
2016 and are considered to be existing affected sources as defined in
563.7882(b). Per $63. 7883(9)(1), the compliance date is June 24, 2024.

Based upon information and belief formed after a reasonable inquiry, l, as a responsible official of
the above-mentioned facility, certify the information contained in this report is accurate and true to
the best of my knowledge. The above-mentioned facility has complied with the relevant standard
or other applicable requirements referenced in the relevant standard and described as follows.
Average total volatile organic hazardous air pollutant (VOHAP) concentrations for remediation
material management units was determined, according to the procedures in 63.7943, and
recorded the average VOHAP concentration of the remediation material placed in the affected
remediation material management unit.

SECTION lII
Describe the methods you used to determine compliance. [563.9(hX2)(iXA); 563.7937]
SECTION IV
Describe the results of any performance tests, opacity or visible emission observations,
continuous monitoring system (CMS) performance evaluations, and/or other monitoring
procedures or methods that were conducted. tS63.9(h)(2XiXB)I
tnitiat compliance with fhe SR MACT standards (5563 7884 through 63.7887) for each affected source
type was demonstrated by determining the average VOHAP concentration of the Refinery's remediation
materials. The Refinery used knowledge of operations and species-specific chemical concentration test
data following the requirements ln $63.7943(c) to determine average VOHAP concentrations in
remediation materials. Section ll above includes a signed statement that the average VOHAP
concentration was determined according to the procedures in 563.79431.
The total quantity of the HAP listed in Table 1 to fhe SR MACT that is contained in the remediation
material excavated, extracted, pumped, or otherwise removed during all of the site remediations
conducted at the Refinery is /ess than 1 megagram (Mg) annually (this includes evenf driven, intermittent
cleanups of remediation material as well as on-going remediation activities). The Refinery keeps records
of remediation activities and a description of the methodology and data used to determine the total HAP
co nte nt of th e re med i atio n m ate ri a/. fS 63. 7 88 1 (c) ( 1 ) - (2) l.
No slte remediation activities at the Refinery are subject to performance testing requirements. Opacity
and/or visible emisslon observations are not applicable per 63.6(h).
SECTION V
Describe the methods you will use to determine continuous compliance, including a description of
monitoring and reporting requirements and test methods. [563.9(hX2)(i)(C); 563.7938]
The Refinery will update the totalquantity of VOHAP that is contained in the remediation material
excavated, extracted, pumped, or otherwise removed during all site remediations conducted annually to
verify the total is /ess than 1 Mg. The Refinery will perform a new determination of total VOHAP
concentration in the remediation material when operation changes that could cause the average VOHAP
concentrations to increase.
SECTION VI
Describe the type and quantity of hazardous air pollutants (HAP) emitted by the source (or
surrogate pollutants if specified in the relevant standard), reported in units and averaging times
and in accordance with the test methods specified in the relevant standard. tS63.9(hX2XiXD)I

40 CFR 63 Subparl GGGGG - Notification of Compliance Status (NOCS) Report
The types of HAPs emitted from affected sources may include but are not limited to benzene, biphenyl,
1,3-butadiene, carbon disulfide, cumene (isopropylbenzene), ethylbenzene, hexane, methyl tert butyl
ether, naphthalene, styrene, toluene, 2,2,4-trimethylpentane, and xylenes (isomers and mixtures). The
Refinery is not required to quantify the HAP emisslons to the atmosphere from the affected sources; the
remediation sysfems are managed below VOHAP concentration levels that trigger SR MACT control
levels (i.e. betow 10 ppmw (process vents) and 500 ppmw (RMMUs)). VOHAP concentration of the
remediation material managed in the affected sources is determined using knowledge of the remediation
material methods in 63.7943.
SECTION VII
lf the relevant standard applies to both major and area sources, present an analysis
demonstrating whether the affected source is a major source (using the emissions data
generated for this notification). tS63.9(h)(2)(iXE)l
ffre Sn MACT onty applies to maior sources. The Refinery is a major source of HAP.
SECTION VI!I
Describe the air pollution control equipment (or method) for each emission point, including each
control device (or method) for each hazardous air pollutant and the control efficiency (percent) for
each control device (or method). tS63.9(h)(2)(iXF)l
frtot appncaOte - fhe sfte remediation activities at the Refinery meet exemptions from controls under fhe SR
MACT as described under Section ll above.
SECTION IX
A. Did you submit an application for construction or reconstruction under 563.5(d) that contained
preliminary or estimated data? [563.9(hX5)]
