USEPA Questions/Concerns
8/5/2015
1. What is the current oil/gas well production per pad? 2. Requesting the actual time of day that the tanks were gauged on Monday,
8/3/15 3. Stick flare vs. Combustor: separate functions - what operations serve
which one? a. Stick Flare - emergency flare when the VRU is not operating, the gas off the LP equipment will vent to the stick flare b. Combustor - gas from the tank battery
4. Would like to see the flare/combustor manufacturer specs and operating recommendations: operating temperatures to operate at maximum % efficiency burn a. To achieve X efficiency, what temperature must be achieved/sustained? b. Same company/manufacturer?
5. Why doesn't the flare/combustor have an auto alert that sends notification communication when the pilot is out (operating status)? a. Concerned with delays/length of time that combustor is not operating i. Production pads have intermittent/discontinuous daily inspections & pumpers are not alerted to circumstances
6. Why do some pads have Gun Barrel Tanks "GB" and other do not? a. Early design - a settling tank to separate the oil and water b. Used when atmospheric pressure, gravitational force, and retention time are sufficient for adequate separation of oils, water, and gas where no heat is required for separation c. Gravity feed allows water to enter oil tanks - Discontinued the installation on our pads
7. Note: Interested in the fact that the dump valves and fuel gas supply valves release gas under normal operations
8. What notification is received that list which sites are "Quad 0"...40 cfr. 60 subpart 000? Group 1 or 2? Trying to get a sense if combustor needs to be in operation.

RE: Post Inspection Information Request Gulfport Energy
Dear Ms. Topinka:
Gulfport Energy respectfully submits this letter per the information request following recent inspections at our facilities in Southeast Ohio on August 3 and 4,2015. Below is a list of questions and answers per your request
1. What emissions do the "stick" flares control?
These flares are designed to capture emissions from the LP system in the event the LP compressor (VRU) goes down or is unable to handle the amount of flash being generated in LP separator, heater treater or vapor recovery tower (VRT).
2. Provide downtime for any of the combustors at the sites visited from January 1,2014 to August 4,2015. How is it determined that the combustor is down?
Gulfport has been working on tying in the flares to our SCADA system which will send an alarm to the field and management when combustor pilot is not lit. This alarm works off a thermocouple which senses heat from the pilot gas flame. Since January of this year, we have pulling wire from our PLC to all the combustors in the field. As of August 10,2015, we now receive email notification when a combustor is down. See "Attachment 1Combustor Downtime Alarms" for copies of email notifications demonstrating combustor downtime alarms. We also receive a notification when the alarm is resolved.
I have also attached a few records of invoices dating back to January of 2015 to illustrate are efforts in tying in the combustors to our SCADA system. See "Attachment 2-Combustor Monitoring Invoices".
In addition to the combustor alarm notifications, we now receive an hourly or monthly report by facility illustrating the flare downtime in hours through our field visor system.
3. Manufacture specifications for the flares and combustors at each site visited.
See "Attachment 3-Combustor and Flare Specs".
4. The latest tank gauging activities prior to the visit on August 3 or 4,2015.
See "Attachment 4-Tank Gauging".
5. Monthly production data to include condensate and produced water from January 1,2014 through July 31, 2015.
See "Attachment 5-Production Data".
6. Provide any 0000 initial notification submitted to a regulatory agency.

ED_001523_00000833-00001
We have all GP 12.1 and 12.2 permits and have accepted a voluntary limit to restrict the potential VOC emissions from each storage vessel to less than 6 tons per year. All of our condensate sites have a closed vent system with VRU's capturing flash vapors that is routed to sales and a stick flare as a backup. We have installed combustors destructing tank emissions.
Additional Detail
In addition to the information request, Gulfport would like to address the issue with the leaking thief hatches on the tanks. We have been conducting our quarterly FLIR camera inspections per the GP 12 air permit and have recognized the issue with leaking hatches during those inspections. We have purchased and installed a new style hatch with a heavier spring which will mitigate the problem. Not all of the hatches have been installed at this time but we are working toward complete installation across the board. Another area of concern is the flame arresters at the combustor. We recently disconnected the piping to inspect the flame arrestors and found many were clogged. This caused back pressure to the tanks resulting in emissions releasing from the hatches. We have seen improvement after installing the new thief hatch and cleaning out the flame arrestors and have implemented a thief hatch and flame arrestor maintenance program.
Our last effort is investigating the facility design of our closed vent system with the assistance of an outside engineering firm. We have already started the process previous to the inspections by running a Hysis model to evaluate emissions to the stick flare and tanks. See "Attachment 6-Hysis Model Stick Flare" and "Attachment 7Hysis Model Condensate Tank".
Gulfport will continue to refine and improve our operations in order to fulfill our commitment to conduct business in a manner that protects human health and the environment while also respecting the social license provided to us by the public and the various governmental organizations that oversee our activities.
It goes without saying, if you have any questions or need additional information, do not hesitate to call me at 405-242-4965.
Respectfully,
Jeff Seal Environmental Manager Attachments

Based on available information and as explained below. EPA finds that Gulfport Energy Corporation (Gulfport) is violating Section IJ 1(e) of the Clean Air Act. 42 U.S.C. 7411(e). Specifically. Gulfport is violating the Standards of Performance for Crude Oil and Natural Gas Production. Transmission, and Distribution found in 40 C.F.R. Part 60. Subpart OOOO as follows:
Statuton and Regulatory Authority
...
J.
The CAA is designed to. among other things, protect and enhance the quality of
the nation's air so as to promote the public health and welfare and the productive capacity of its
population. See Section J 01 (h)( I) of the CAA, 40 U.S.C. 74(H(b)(l).
2.
Section 1 G('b) of the CAA. 42 U.S.C. 741 1(b), requires EPA io publish a list of
categories of stationary sources of air pollution if those sources cause or contribute significantly
to air pollution that may reasonably be anticipated to endanger public health or welfare, and io
promulgate regulations establishing federal standards of performance for new sources within the
source category. These emission standards are known as New Source Performance Standards
(NSPS). and are codified at 40 C.F.R. Part 60.
3.
The NSPS includes Standards of Performance for New Stationary Sources for
Crude Oil and Natural Gas Production, Transmission and Distribution, found in 40 C.F.R. Part
60. Subpart OOOO CSubpart OOOO").
4.
Subpart OOOO, at 40 C.F.R. 60.5430. among other things defines "storage
vessel" as a tank or other vessel that contains an accumulation of crude oil. condensate,
intermediate hydrocarbon liquids, or produced water, and that is constructed primarily of non -
earthen materials (such as wood, concrete, steel, fiberglass, or plastic) which provide structural
support.

6.
Subpart OOOO. al 40 C.F.R. 60.5365(c). provides that a storage vessel affected
facility is a single storage vessel located in the oil and natural gas production segment, natural
gas processing segment or natural gas transmission and storage segment, and has the potential
for volatile organic compound (VOC) emissions equal to or greater than six tons per year as
determined according to 40 C.F.R. 60.5365. The potential for VOC emissions must be
calculated using a generally accepted model or calculation methodology, based on the maximum
average daily throughput determined for a 30-day period of production prior to the applicable
emission determination deadline specified in 40 C.F.R. 60.5365. The determination may take
into account requirements under a legally and practically enforceable limit in an operating permit
or other requirement established under a Federal. State, local or tribal authority.
7.
Subpart OOOO. at 40 C.F.R. 60.5411 (b). requires owners and operators of
storage vessel affected facilities to ensure that covers on storage vessels meet certain
requirements, including that the cover and all openings on the cover shall form a continuous
impermeable barrier over the entire surface area of the liquid in the vessel; each cover opening
shall be secured in a closed sealed position except when certain activities are ongoing: and that
each storage vessel thief hatch shall be equipped, maintained, and operated with a weighted
mechanism or equivalent, to ensure the lid remains properly seated.
8.
Subpart OOOO, at 40 C.F.R. 60.541 J (c). requires owners and operators of
storage vessels using a control device to control emissions to design its closed vent system to
route all gases, vapors, and fumes emitted from the material in the storage vessel to a control
device that meets the requirements of 40 C.F.R. 60.5412(c) and (d): and to design and operate a
closed vent system with no detectable emissions, as determined using olfactory, visual, and o
auditory inspections.

Re: Finding of Violation EPA-5-17-OH-08
Dear Ms. Topinka;
On December 22, 2016 the US EPA issued Findings of Violation EPA-5-17-OH-08 ("FOV") to Gulfport Energy Corporation ("Gulfport") under Section 113(a)(3) of the Clean Air Act, 42 U.S.C. 7413(a)(3). The alleged violations were cited under Section 111 of the Clean Air Act. and the Standards of Performance for Crude Oil and Natural Gas Production, Transmission, and Distribution found in 40 C.F.R Part 60, Subpart OOOO. These alleged violations were more fully described in Paragraphs 23-27 of the FOV and related to a number of Gulfport's facilities, which were listed in Attachments A and B to the FOV ("Gulfport Facilities"). On February 7, 2017, Gulfport met with the US EPA to review and discuss the FOV. Please accept this letter as our written response to the FOV.
GeneralObiections
As a preliminary matter, Gulfport disputes the alleged violations based on US EPA's technical methodology employed to conduct emissions evaluations at Gulfport Facilities. In order to issue the FOV, US EPA utilized an optical gas-imaging ("OGI'') infra-red camera, which observed vapors emitting to the atmosphere from the thief hatches or pressure relief devices on certain production tanks. Gulfport notes two problems with this technique:
1. First, the OGI camera is an observation tool and lacks the ability to determine flow rate or concentration of vapors being emitted. As such, the OGI camera is incapable of determining the volume of emissions. It is untenable to conclude that a device which lacks the capability to conclusively evaluate emissions volumes should be employed to determine whether a particular tank meets the volumetric yearly emissions necessary to trigger Subpart OOOO jurisdiction. For example, consider the US EPA Video, see Attachment "B" (MOVJ326), which was filmed during an August 2015 inspection of Gulfport's Hayes location. The Hayes wells made 2.88 bbls of condensate and 3,184 bbls of water for the month of August 2015. Utilizing standard gravity back calculations, it is easily ascertained that the bbls/ per day extrapolated out for one year is a total of .02 tpy volatile organic compounds ("VOCs") per tank of condensate and .08 tpy VOCs of produced water. In short, the Hayes location video is depicting very small emissions volumes, and, when viewing the video relative to videos taken at other Gulfport Facilities, the emissions appear to be indistinguishable.
2. Secondly, the OGI camera is incapable of distinguishing between VOCs and non regulated greenhouse gas ("GHG") emissions. Meaning, US EPA's emissions evaluation utilized to issue the FOV lacked the ability to proportionately determine the composition of emissions that were observed in the OGI camera footage. It is undisputed that a portion
17cv1906 Sierra Club v. EPA
ED_001523_00000836-00001
of the observed emissions are non-regulated GHG emissions, and if US EPA's observation technique cannot determine composition, the observed emissions are misrepresentative of VOC emissions and should not be utilized to determine whether the Gulfport Facilities are subject to Subpart OOOO jurisdiction.
In summation, US EPA's emissions evaluation technique is insufficient and incapable of
reasonably determining that the Gulfport Facilities meet the requisite volumetric requirements to
be subject to Subpart 0000 jurisdiction.
..
..
As a second preliminary matter, Gulfport fundamentally disputes US EPA's interpretation and use
of `'potential to emit 6 tons per year ("tpy")" as a basis for determining Subpart OOOO jurisdiction
for the Gulfport Facilities. Despite the disagreement in interpretation, US EPA's emissions
evaluation technique lacks the necessary components to determine volume and composition of
emissions - thus, US EPA is unable to adequately determine '`potential." When evaluating the US
EPA's findings in the FOV, fundamental flaws are quite apparent. For example, consider the
sixteen Gulfport Facilities related to the FOV. Based on hydrocarbon production rates in 2016,
ten of these facilities are mathematically incapable of emitting the necessary 6 tpy VOC - even
assuming Gulfport had no emissions controls devices n place. As evidence, I would direct you to
Attachment "A" for 2016 production rates and PTE calculations. Calculations were based on
commonly used E&P tanks v2.0 and the highest Ib/bbl rating from previous pressurized sampling
was used. Clearly, these Gulfport Facilities are not only incapable of emitting 6 tpy of VOCs but
come nowhere close to the required threshold. Yet, US EPA determined in the FOV that each of
these locations was subject to Subpart OOOO jurisdiction, based on OGI videos and a loose
interpretation of "potential to emit".
Specific Responses
..
...
Gulfport makes the following specific comments to Paragraphs 23-27 of the FOV.
23. Gulfport's storage vessels at well pads listed in Attachment A are subject to Subpart OOOO, and based on the above described detectable emissions from storage vessels observed by EPA staff, Gulfport has failed to ensure that the covers on its storage vessels meet certain requirements, including that the covers and all openings shall form a continuous impermeable barrier over the entire surface area of the liquid in the vessel, and that each cover opening shall be secured in a closed, sealed position except when certain activities are ongoing, violating 40 C.F.R. 60.541 I (b).
Gulfport Response: Gulfport elected to opt out of Subpart OOOO through the Ohio GP 12.1/12,2 permits by accepting to voluntarily limit and restrict the potential VOC emissions from each storage vessel to less than 6 tons per year per 40 CFR 60.5365(e).
24. Based on the above described detectable emissions from storage vessels observed by
EPA staff, Gulfport has failed to design its closed vent systems to route all gases, vapors and
fumes emitted from the material in the storage vessels to a control device, and to design and
operate closed vent systems with no detectable emissions, as determined using olfactory, visual,
and auditory inspections, violating 40 C.F.R. 60.5411 (c),

Gulfport elected to opt out of Subpart 0000 through the Ohio GP 12.1/12.2 permits by accepting to voluntarily limit and restrict the potential VOC emissions from each storage vessel to less than 6 tons per year per 40 CFR 60.5365(e).
25. Based on, among other things, Gulfport's failure to meet certain cover, closed vent and control device requirements, demonstrated by the above described detectable emissions from storage vessel observed by EPA staff, Gulfport has failed to demonstrate initial compliance at its storage vessel affected facilities listed in Attachment A, violating 40 C.F.R. 60.54 10(h).
Response: Gulfport elected to opt out of Subpart 0000 through the Ohio GP 12.1/12.2 permits by accepting to voluntarily limit and restrict the potential VOC emissions from each storage vessel to less than 6 tons per year per 40 CFR 60.5365(e).
26. Gulfport's storage vessels at well pads listed in Attachment B are subject to Subpart 0000, and based on Gulfport's failure to operate its combustion control devices with a present and continuously burning pilot flame at its storage vessel affected facilities listed in Attachment B, Gulfport has violated 40 C.F.R. 60.5412(d).
GulfportResBonse: Gulfport elected to opt out of Subpart 0000 through the Ohio GP 12.1/12.2 permits by accepting to voluntarily limit and restrict the potential VOC emissions from each storage vessel to less than 6 tons per year per 40 CFR 60.5365(e).
27. Based on the above described detectable emissions from storage vessels, and absence
of a present and continuously burning pilot flame on its combustion control devices observed by
EPA staff during the August 2015 inspections, Gulfport failed to operate its storage vessel affected
facilities in a manner consistent with good air pollution control practice for minimizing emissions,
violating 40 C.F.R. 60.5370(b).
..
Gulfport Response:
Gulfport's combustors and flares did utilize a continuously burning pilot at the time
of the inspection, however the pilot was out. Gulfport was in the process of
installing flame rod sensors to detect the presence of a flame for all combustors
prior to the inspection. The sensor installation was completed by the end of August
2015. In the event the pilot goes out, an alarm is sent to the pumpers through our
SCADA system.
Conclusion
For the foregoing reasons, Gulfport objects to the FOV. Regardless of Subpart 0000 jurisdiction, Gulfport continues to work to develop new techniques that would limit emissions from thief hatches and welcomes the opportunity to work with US EPA to resolve this matter.
Sincerely,
..
