Section I - INTRODUCTION
PURPOSE OF THE INSPECTION

EPA inspectors Sarah Frey (Region 6) and Chris Williams (Headquarters) accompanied by Richard
Helmich (National Enforcement Investigations Center, "NEIC"), David Mahoney (NEIC), and Ali Gitipour
(Office of Research and Development) arrived at the MPLX/Pin OakTerminals, LLC Mt. Airy Terminal LLC
at 2:10 pm on April 20, 2022 for an unannounced inspection. We were accompanied by Louisiana
Department of Environmental Quality inspector Brandon Saunier. We met with John David Neal,
Terminal Manager, and Patrick Williams, Field Safety. Credentials were presented to John David Neal
and we informed him that this was an EPA inspection to evaluate potential sources of excess emissions
using EPA's Geospatial Measurement of Air Pollution ("GMAP") vehicle and evaluate compliance with
the facility's Title V Permit and the Clean Air Act. The scope of the inspection is a partial compliance
evaluation ("PCE"). This inspection occurred as part of the Administrator's Multi-Scale Monitoring
Project called the Pollution Accountability Team ("PAT").

FACILITY DESCRIPTION

The Mt. Airy Terminal is a liquid storage terminal that operates under Permit Number 2580-0005l-Vl
issued February 6, 2020.

Section II - OBSERVATIONS

The NEIC GMAP was driven by Mr. Mahoney and the instruments were operated by Mr. Helmich and
Mr. Gitipour. A facility representative, Mr. Williams, was present in the GMAP. Inspectors Dr. Frey, Mr.
Williams, and Mr. Saunier were escorted in a facility vehicle by Mr. Neal. Mr. Neal led the GMAP
throughout the tank terminal, where air pollution data was collected and recorded. A full report from
the GMAP will be issued by NEIC at a later date.

Downwind of Tank 110-20, Volatile Organic Carbon ("VOC") emissions were detected intermittently
between 200 and 300 parts per billion ("ppb"). Mr. Neal identified the contents of the tank as Vacuum
Gas Oil and confirmed the tank was static, not being loaded or unloaded. Mr. Williams recorded two
videos using an Optical Gas Imaging ("OGI") camera. The videos show intermittent hydrocarbon
emissions exiting the fixed roof tank from the center conservation vent. See Videos 1 and 2.

Downwind of Tank 150-2, VOC emissions were detected between 900 and 1000 ppb. Mr. Neal identified
the contents of the tank as gasoline and confirmed the tank was static, not being loaded or unloaded.
Mr. Williams and Mr. Helmich attempted to locate the source of the emissions using OGI cameras, but
were unsuccessful. The tank was equipped with an internal floating roof.

Section III - AREAS OF CONCERN

Richard Helmich, Sarah Frey, and Chris Williams conducted a closing conference at MPLX Mt. Airy
Terminal LLC at 4 pm on April 20, 2022 for the inspection. During the closing conference, Mr. Helmich

reviewed the emissions detected by the GMAP during the inspection. Dr. Frey confirmed that the OGI
videos taken would be subsequently shared with the facility electronically. We observed no areas of
concern at the time of the inspection.

Section IV-FOLLOW UP

No additional information was received by EPA after exiting the Facility on April 20, 2022.
