The facility was inspected under the Clean Air Act (CAA) for compliance with 40 C.F.R. Part 63, Subpart CCCCCC - National Emission Standards for Hazardous Air Pollutants for Source Category: Gasoline Dispensing Facilities (NESHAP 6C). Inspection activities included observation of a fuel delivery event by the EPA inspectors and a request
for records required to be maintained under NESHAP 6C.
The following are areas of concern identified during the inspection or records review: 1. An Air Pollutant Emissions Notice, or APEN, has not been submitted
to the Colorado Department of Public Health and Environment's (CDPHE) Air Pollution Control Division (APCD). Typically, APENs are required upon startup and must be updated every 5 years for this source category.
2. Components of the tank and associated vapor equipment were not vapor tight during the fuel delivery event, as required by Item 1(b) of Table 1 of NESHAP 6C. The following emissions were observed during the fuel delivery portion of EPA's inspection: a. During simultaneous regular unleaded fuel (RUL) and diesel fuel tank filling, vapors were observed from the RUL tank's pressure/vacuum-style (P/V) vent.

Fuel Delivery Event Observation:
A fuel delivery event was observed by the EPA inspectors. The inspectors used a forward-looking infrared (FLIR) camera to record optical gas imaging (OGI) videos of gasoline vapors, and a toxic vapor analyzer (TVA) to measure gasoline vapor concentrations1. Any auditory, visual, and olfactory (AVO) observations were also recorded. See Appendix A for a list of photographs and videos recorded during the fuel delivery inspection.
Components of the refueling activity which Description/Observations (including any OGI or AVO observations)
were observed:
Conditions of Equipment prior to Equipment was observed to be capped and covered prior to refueling event fueling.
Connection of fuel
The vapor recovery hose was first connected to the vapor recovery tank and truck header. Next, the fuel hose was
and vapor lines prior connected to the fuel pipe of the tank, and finally the fuel hose
to fuel transfer was connected to the truck header.
During simultaneous fueling of the RUL and diesel tanks,
vapors were observed with the FLIR from the vapor vents. See
Maintenance of fuel FLIR0049. Specifically, emissions were observed from the
and vapor line northern cluster of vapor vents, closest to the store building. connections during There were two vents in this cluster; one was equipped with a

P/V-style vent, and the other was not. Based on this
observation, the P/V-style vent was likely connected to the RUL
tank. Emissions were observed from both vents. See FLIR0051.

Notes
1 The TVA was calibrated using 500 parts per million (ppm) and 10,000 ppm methane gas standards. The methane concentrations recorded on the TVA were then converted to a ppm concentration as propane using a conversion factor of 3. This provides a conservative conversion to propane, using the guidance put forth in EPA's "Frequently Asked Questions (FAQ) for Method 25A". See https://www.epa.gov/sites/default/files/2016-08/documents/method25a_faq.pdf.
