Purpose of Inspection: Inspect the benzene waste operations and volatile organic compounds
(VOC) emissions from wastewater systems

Facility Type: Petroleum Refinery

Regulations Central to Inspection: Refinery wastewater subject to the New Source
Performance Standards for VOC Emissions from Petroleum Refinery Wastewater Systems, at 40
C.F.R. Part 60, Subpart QQQ (Subpart QQQ), and the National Emissions Standards for
Hazardous Air Pollutants for Benzene Waste Operations, at 40 C.F.R. Part 61, Subpart FF
(Subpart FF)

Arrival Time: April 13, 2022, 2:00 pm
Departure Time: April 15, 2022,1:20 pm

Inspection Type:

M Unannounced Inspection
~ Announced Inspection

Opening Conference

M Presented Credentials
M Stated authority and purpose of inspection
M Provided CBI warning to facility

The following information was obtained verbally from MPC personnel unless otherwise noted.
Process Description:

MPC provided an overview of the overall flow of the benzene waste streams, including those
that are controlled by Subpart FF and those that overlap with Subpart QQQ. MPC operates two
desalter units, one installed in the late 1970's (desalter #10) and one installed in the late 2009
(desalter #210). Each of the desaIters operate with a benzene flash column to remove any
benzene prior to sending the streams for further treatment. Originally, MPC managed waste
from each desalter to an American Petroleum Institute (API) designed oil/water separator (OWS)
respective of installation timing. However, since 2009, MPC has modified its benzene waste
operations a few times such that each desalter sends material primarily to tank #100-5 with a
smaller stream being sent to either API oil water/separator #1 (for desalter 10).

The wastewater from tank#100-5 is sent to two dissolved nitrogen floatation units (DNF) that
operate in parallel. The DNF's were installed in late 2020.

In addition to the two desalter streams, the refinery generates other waste streams that are sent to
each of the API oil/water separators. Each API oil/water separator streams route the benzene
emissions to a two-carbon bed system, that is operated in parallel. MPC indicated that the
carbon was changed last on one of the beds for API oil/water separator #1 in 2017, and there has
been no carbon bed change for API oil/water separator #2 since its installation in 2010.

-------
Staff Interview: EPA had a brief interview with Mr. Marvin Alberto on April 15, 2022
regarding his oversight of the Subpart FF program. Mr. Alberto is responsible for conducting
EPA Method 21 and visual inspections on the components that MPC has identified as needing
that type of monitoring. In addition, Mr. Alberto conducts carbon canister sampling for
breakthrough by sampling the outlet of the carbon beds for 5 parts per million (ppm) of benzene
by using a benzene calibrated portable photo-ionization detector instrument.

Tour Information
EPA Tour of the Facility: Yes

Data Collected and Observations:

•	MPC indicated that the covers of API #1 OWS, API #2 OWS, the stormwater sump,
AIS3 Sump, and the ISBL sump are not monitored with Method 21 to verify that there no
detectable emissions above 500 ppm; however, a seal gap measurement is performed
semi-annually for the API's.

•	EPA observed a pressure relief valve to have a bypass to atmosphere near associated with
the benzene stripper supporting the area 10 desalter system.

•	EPA observed a vacuum truck with personnel cleaning an oil float on both days that we
were onsite on top of API #1 OWS. MPC operations indicated that this is routine during
any rain events and at other times.

•	EPA observed no sealant at multiple spots, cracked seals, and a warped-open cover on the
stormwater sump located next to API #1 OWS.

•	Two carbon canisters controlling emissions from API #1 OWS and API #1 OWS effluent
sump are used in parallel.

•	MPC indicated that the effluent from the sour water strippers is routed to API #1 OWS
effluent sump, and the temperature of that stream is between 160-200°F.

Photos and/or Videos: were taken during the inspection.

EPA imaged hydrocarbon emissions using a FLIR optical gas imaging camera, Model
GFx-320. In addition, this camera was also used to take digital pictures and videos as
well. See Appendix 1 for the summary of the videos and pictures taken.

Field Measurements: were taken during this inspection.

See Appendix B for a summary EPA's field measurements.

Concerns: EPA identified the follow areas of concern:

1.	MPC has not maintained a wastewater drawing reflecting the benzene waste operations,
and unable to provide how compliance with the 6 Megagram control option is maintained
for Subpart FF;

2.	MPC has never conducted no detectable emission (NDE) monitoring on the API OWS's,
and other sump covers that are part of the controlled system for Subpart FF.

3.	Routine oil float on top of API #1 OWS indicative of the floating roof not creating a seal
or designed to NDE under Subparts QQQ and FF.

4.	MPC may not be meeting the 6 Megagram control option based on the several of the
waste managements being considered controlled but not operated as controlled.

5.	Pressure relief valves subject to Subpart FF having an atmospheric bypass.
