OPERATING STATUS: Operating.

PROCESS DESCRIPTION: Sawtooth Caverns operates a Natural Gas Liquids (NGL) storage
facility. The facility receives NGL's and refined products
(gasoline and diesel) and ethanol from trucks and railcars. The
emissions from the transfer of gasoline from trucks and railcars
are controlled with a Vapor Combustion Unit that operates
during loading and unloading. The gasoline is temporarily stored
in two 1000 bbl fixed roof tanks with internal floating roofs.
Diesel is temporarily stored in two insulated 1000 bbl fixed roof
tanks with internal floating roofs. The NGLs and refined
products are then pumped into underground salt caverns for long
term storage. The underground salt caverns contain brine which
is displaced by the NGLs and is pumped up to the surface into
one of two storage ponds. Any gasses that are brought up with
the displaced brine are combusted in an integrated enclosed
combustor on the north side of the brine ponds. When NGLs or
refined products are removed from the salt caverns, brine is
pumped from the storage ponds back into the caverns to replace
the removed products.

1.0 INTRODUCTION
Sawtooth Caverns, LLC contracted John Zink Air Source Testing Group (JZASTG) to perform air
emission testing services for one Vapor Combustion Unit (VCU) at the Sawtooth NGL Storage Facility
located in Delta, Millard County, Utah. Concentrations of total volatile organic compounds (VOC, as
total hydrocarbons [THC] measured on a propane detection basis), carbon monoxide (CO) and carbon
dioxide (CO2) were measured in the exhaust of the VCU. The total flow rate, temperature, pressure
and inlet vapor hydrocarbon concentrations were simultaneously recorded upstream of the vapor
combustion zone. The facility was monitored for VOC leaks immediately before the testing began using
a portable hydrocarbon analyzer. The pressure of the vapor system was monitored in each loading
bay.
The purpose of the test was to determine the compliance status of the VCU with respect to provisions
found in the Code of Federal Regulations, Title 40, Part 60 (40 CFR 60), Subpart XX (“Standards of
Performance for Bulk Gasoline Terminals”), 40 CFR 60.503(b) and 40 CFR 60.503(d). 40 CFR 63,
Subpart BBBBBB (“National Emission Standards for Hazardous Air Pollutants for Source Categories:
Gasoline Distribution Bulk Terminals, Bulk Plants, and Pipeline Facilities”) and specific conditions found
in Utah Department of Environmental Quality (UDEQ) Permit Number DAQE-AN143260008-22. Tests
were completed while loading on bays 1, and 2. The emissions from these bays are controlled by the
VCU identified in the permit as Emission Point Number II.A.9.
This document presents the results for compliance testing of the VCU. Table 1-1 presents an executive
summary of results. Section 2 provides a detailed summary of results as well as identification of the
owner and contact, the physical location of the site, test contractor contact information and identification
of specific test methods. Section 3 details Quality Assurance and Quality Control procedures and
documentation. The appendices to this document provide raw field data, examples of calculations and
formulae utilized to derive all results presented in this document, records of fuel loading, calibration
certification documents and copies of relevant QA/QC procedures.
1.1 Test Objectives
Determine compliance with applicable federal and state permit limitations
Quantify the total amount of VOC released to the atmosphere
Verify that the vapor collection system is leak-free
Validate the test matrix by loading at least 300,000 liters (~80,000 gallons) of gasoline in two
test periods a minimum of six-hours in length per 40 CFR 503(c)(1)
Monitor the vapor collection system pressure during tanker truck loading and record the highest
instantaneous pressure for each loading bay per 40 CFR 60.503(d)(2)

and the information contained herein.
1.2 Process Description and Operation
This facility owns and operates a John Zink VCU as an exhaust emission control device. The
emissions from this unit are the subject of this report.
The fuels loading/distribution terminal has a total of 2 bays for loading into tank trucks. A process
diagram of the loading rack detailing the number of loading arms at each bay and type of product
loaded may be found in Appendix A of this report. As gasoline and/or other fuels are loaded into a
tanker truck the displaced vapors are pushed by air displaced during trailer loading through a closed
venting system to the VCU. After passing through a detonation arrestor to prevent backward flame
propagation vapors enter the burner area. There is no set pattern of loading (the trucks load on a first
come, first served basis). However, the usual periods of heavy loading activity are in the early morning
and late afternoon. The source test was timed to coincide with these periods.
Concentration measurements were made both upstream and downstream of the combustion zone.
The upstream sample was obtained by extracting a small sample from the exhaust of a turbine meter
temporarily installed on the vapor inlet line of the VCU. The downstream sample was obtained from a
sample port approximately five feet below the combustor stack exit to atmosphere. This port was
accessed via manlift.
1.3 Complications during Sampling Event
A test was completed on October 6, 2022, during which 173,739 liters (45,897 gallons) of gasoline was
loaded. Because the facility did not load the required gasoline volume, an additional six-hour test was
performed on October 7, 2022, according to 40 CFR 60.503(c)(1). No other deviations from the
published test methods or the accepted source test protocol were made during this sampling event. No
adverse test conditions or environmental conditions which may have impacted results were
encountered during the completion of this event. The test program was conducted according to the
site-specific test plan using procedures deemed acceptable by the UDEQ and the United States
Environmental Protection Agency.

2.0 SUMMARY

Detailed test results and summary information are presented and discussed in this section.

The VOC emissions rate was 6.53 mg/liter of gasoline loaded, which is less than the permitted limit of
35 mg/liter of gasoline loaded. The total quantity of gasoline vapors emitted from the VCU during the
test period was found to be 3.72 pounds (1,687,916 mg) of VOC, measured and quantified on a
propane detection basis. The total volume of gasoline loaded during test period was 68,330 net gallons
(258,657 liters). Because less than 300,000 liters of gasoline was loaded on October 6, 2022, a
second six-hour test was completed on October 7, 2022, this meets the requirements of specified in 40
CFR 60.503(c)(1). The actual time of active loading was 5.75 digital hours. Active loading is defined
as periods inlet flow was being received. Total test time includes all time from the start of the test
period until completion of the test.

The test matrix to evaluate compliance consisted of a period of greater than six hours (6:26
hours:minutes on October 6, 2022 and 6:24 hours:minutes on October 7, 2022) while the unit was
operating at normal conditions. During the test period, quantities of VOC (propane detection basis)
were measured from the inlet of the VCU using the procedures of EPA Method 25B. Inlet volume was
calculated using EPA Method 2A (direct measurement of flow). Quantities of THC, CO and CO2 were
measured in the source exhaust using EPA Methods 25A, 10 and 3A, respectively. Exhaust flow was
calculated using the equations of EPA Method 2B.

Test results are based on the one-minute interval averages recorded by the data-logging system. Five-
minute averages of these measurements were calculated to determine VOC emissions. This is
consistent with 60 CFR 60.503(c)(4). Table 2 presents these averages.

For the direct analysis of VCU inlet and exhaust stack gas, two extractive systems were used to obtain
samples of inlet and exhaust VOC and exhaust CO and CO2. Each sample was extracted using a
stainless steel/Teflon™ diaphragm pump. For the inlet sample a portion of the stream just past the
turbine meter was extracted and directed to the test trailer via Teflon™ sample line. This line was not
heated due to the risk of explosion given the high percent level concentrations of the sample (EPA
Method 25A, §5.2). The sample passes through a Nafion Membrane dryer to remove water without
effecting hydrocarbon concentration, then is routed through a rotameter for flow control and to the NDIR
analyzer for measurement. The exhaust gas sample was continuously pulled through a heated Teflon
sample line (maintained at 250 ± 20°F). A portion of the heated, unconditioned sample was delivered
to the FID analyzer. The remainder of the sample was passed through a peristaltic condenser to
remove moisture and then partitioned to the CO and CO2 analyzers through a manifold and rotameters
for flow control. All portions of each sample system are manufactured from inert material. A list of
instruments utilized for this sampling event may be found in §2.5. A diagram of the sampling system is
in §2.7.

As specified in 40 CFR 60.503(b) [and as referenced in 40 CFR 63.11092(a)(1)(i)] the terminal’s vapor
collection system was monitored using EPA Method 21 to identify any leaking components. A leak

detection threshold of 500 ppm as methane was used to identify any leaking components. The survey
included all valves, flanges, fittings, seals, check valves, etc. No leaks were detected during this
survey.

The vapor collection system pressure was monitored at each loading bay during the sampling event.
Data was recorded electronically at one-minute intervals during loading with the highest instantaneous
pressure noted. The highest instantaneous pressure recorded was 11.1” H2O on Bay 1.

3.0 QUALITY ASSURANCE and QUALITY CONTROL

All sampling was performed following standard EPA protocols as presented in 40 CFR 60, Appendix A.
The test data was checked for completeness, thoroughly documented and subjected to a rigorous peer
review process.

3.1 Equipment Calibration and Analytical Technique

All testing equipment used to conduct emission measurements are maintained according to the
manufacturer’s instructions to ensure proper operation. Calibration and quality assurance activities are
completed on each measurement device according to procedures specified by the EPA.

3.1.1 Inlet/Outlet THC Continuous Emission Monitors
Upon arrival at the site the inlet and outlet instruments were activated and allowed to warm
up per the manufacturer’s instructions. A four-point calibration error test was performed
on each analyzer at the beginning of the day. Vendor-certified calibration gases
containing propane was used for this calibration of the inlet analyzer. The inlet analyzer is
designed to measure THC as its’ carbon equivalent; therefore, the instrument readings are
equivalent to the calibration gas concentrations. The outlet analyzer was calibrated with
EPA Traceability Protocol (EPA-600-R-12-531) propane standards with results reported as
VOC on that measurement basis. The analyzers are designed to measure THC as its’
carbon equivalent; therefore, the instrument readings are equivalent to the calibration gas
concentrations.
Calibration error tests were performed on each analyzer by introducing the zero and
calibration gases through the entire system to establish a linear response line as directed
in EPA Method 25A §8.4. The zero and high-level calibration gases were introduced in
sequence with the analyzer being adjusted as necessary to record the proper values. The
predicted values for the mid- and low-level gases were then calculated. These gases
were then introduced successively to the measurement system. The predicted response
was then compared to the actual response. The differences between the respective
responses was less than 5% of the respective calibration gas values.
The inlet and outlet sampling systems were then evaluated for response time. For each
system, the zero gas was introduced through the entire measurement system and allowed
to stabilize. The high-level gas was then introduced. The time from the concentration
change to the measurement system response equivalent to a 95% step change was
recorded. This process was repeated three times and the results were averaged.
Following the completion of each test period, sample system drift was determined in the
manner prescribed in EPA Method 25A §8.4. 2. The zero- and mid-level calibration were
introduced in sequence to the measurement system. The analyzer response was
recorded. The results of these tests did not exceed 3% of span; therefore, no corrective
action was required.

3.1.2 CO and CO2 Continuous Emission Monitors
Non-dispersive infrared analyzers were used for CO and CO2 concentration
measurements in conformance with the specifications of EPA Methods 10 and 3A,
respectively. The CO analyzer uses gas filter correlation to eliminate interference from
CO2 or moisture. A calibration error test was performed on each monitor by routing low,
high and mid-level calibration gases directly to each analyzer. The calibration error test for
each met the requirements of the reference methods. After the calibration error test, a
sampling system bias test was completed. The calibration gases most closely resembling
the expected stack gas concentration was routed through the entire sampling system
including calibration valve, sample line and moisture removal system. All sample system
bias tests met the reference method requirements. The upscale and downscale response
time of the sample system was determined during the initial bias test. The longest elapsed
time was chosen and the response time for the system. No test period began until at least
twice this response time had elapsed. Sample system bis and drift tests were completed
at the conclusion of each test period, with the resulting corrected value being applied to all
measured concentrations of CO and CO2 preceding the calibration. Drift is defined in EPA
Method 7E §3.1.6 as referenced in Methods 10 and 3A as the value derived by subtracting
the pre-run bias concentration from the post-run bias test concentration expressed as a
percentage of calibration span. All sample system quality assurance test results met the
requirements of the test methods.
Volumetric Flow Rate
The turbine meter used for outlet flow rates was calibrated prior to testing in accordance
with EPA methodology. A post-test calibration check was also completed on the meter.
Calibration documentation may be found in Appendix E. That documentation shows that
the difference in pre- and post-test calibrations differed by less than 5% as specified in
EPA Method 2A, §10.1.8.
The temperature sensor used for this sampling event was checked at ambient temperature
and compared to a reference thermometer. The sensor agreed within 2% of the reading of
the reference thermometer and the data collected is valid in accordance with EPA Method
2A, §10.2. The barometer utilized was calibrated against a mercury barometer prior to the
field test.
3.1.3 Portable Hydrocarbon Analyzer (leak detector)
An RKI portable analyzer equipped with a catalytic oxidation detector was used to monitor
the vapor collection system during tank truck loading. The analyzer was calibrated with a
10,000 ppmv/% certified methane standard. Leaks were defined as exceeding a threshold
of 500 ppm methane. The monitoring includes all valves, flanges, seals, check valves and
other equipment in gasoline service and conformed to EPA Method 21 procedures. Prior
to sampling, the calibration precision of the instrument was determined per EPA Method
21, §8.1.2. Response time met the criteria established in EPA Method 21, §8.1.3. These
procedures are documented on a field data sheet found in Appendix A of this report.

3.1.4 Pressure Monitoring of Vapor Collection System
The pressure at the vapor hose connection at each of the loading bays was monitored
using pressure manometer with a range of 0-20” H2O. The pressures were monitored on
multiple loads at each bay with the highest instantaneous pressure on each load being
recorded. The documentation for this monitoring may be found in Appendix A of this
report. Typically, monitoring continues until a “worst case scenario” is noted. The facility
is accepted as meeting the standard presented in 40 CFR 60.502(h) if the worst-case
pressure is less than the citation.
3.1.5 Data Acquisition and Handling System
The electronic output signals of the continuous analyzers as well as the turbine meter
volume, temperature and pressure were converted to a digital format and stored by a
computerized data acquisition and handling system (IntelliLogger™ IL-80) with an
interrogation frequency of one (1) second creating 60-second averages. The system
translated this digital format into the proper units and stored them to disk. The system
provides resolution of less than 0.5% of the calibration span of each analyzer. Logged
data records are presented in Appendix D.
3.2 Fuel Loading Data

During the test, terminal personnel collected fuel loading data using bills of lading (BOL) generated by
the site’s automation system. Each load is documented by company and presents vehicle log in, load
start and end times, and the quantity and type of product(s) loaded. This information generates a BOL
at the end of loading which documents gross and net gallons loaded. This information was provided to
JZASTG as a record of volume to be utilized in the calculation of mass emissions in terms of the
standard. To successfully obtain permission to load, each trailer must have a current certificate of leak
tightness (per EPA Method 27) on file at the facility. This documentation is available upon request.
