                                    Summary
On January 25, 2018, the EPA received an application from Anadarko Uintah Midstream, LLC (Anadarko), requesting a synthetic minor permit for the Ouray Compressor Station (Ouray) in accordance with the requirements of the Tribal Minor New Source Review (MNSR) Permit Program. This permit action will apply to an existing facility operating on the Uintah and Ouray Indian Reservation in Utah. The physical location is Latitude 40.070928N, Longitude -109.491817W, in Uintah County, Utah. The EPA held a public comment period for the proposed permit from July 30, 2019 to August 28, 2019. The EPA did not receive any comments during the public comment period and, therefore, did not make any changes to the proposed permit per public comment. The EPA did however, make one minor administrative change to the final permit, removing unnecessary language from the proposed permit regarding engine control compliance reporting (conditions 1 and 2 under Section G) that had been inadvertently added.
This permit does not authorize the construction of any new emission sources, or emission increases from existing units, nor does it otherwise authorize any other physical modifications to the facility or its operations. This permit is intended only to incorporate required and requested enforceable emission limits and operational restrictions from a March 27, 2008, federal Consent Decree (CD) between the United States of America (Plaintiff), the State of Colorado, Rocky Mountain Clean Air Action and the Natural Resources Defense Council (Plaintiff-Intervenors); and Kerr-McGee Corporation (Civil Action No. 07-CV-01034-EWN-KMT) and the January 25, 2018 synthetic MNSR application. According to Anadarko, Ouray began operation around January 1, 2000, before the effective date of the MNSR Permit Program (August 23, 2011), and was therefore not subject to any preconstruction authorization requirement. The legally and practicably enforceable CD requirements applied to Ouray before the effective date of the MNSR Permit Program and established the source as a synthetic minor source with regard to the Title V Operating Permit Program at 40 CFR part 71 (Part 71), because the CD limited allowable emissions of carbon monoxide (CO) to a level below the major source threshold (see 40 CFR 71.2). In response to the permit application, the EPA is using the authority at 40 CFR 49.158 to issue a synthetic MNSR program permit that incorporates enforceable emissions limits and restrictions that were previously established through the CD.
Anadarko requested enforceable requirements, consistent with the CD, for the installation and operation of one low-emission tri-ethylene glycol (TEG) dehydration system for control of volatile organic compound (VOC) emissions. Anadarko also requested enforceable requirements for installation and operation of a flare to control VOC emissions from natural gas condensate and produced water storage tanks at the facility, including an associated average daily production limit for natural gas condensate and produced water processed through the tanks. Anadarko also requested an enforceable requirement to install and operate only low-bleed, no-bleed or instrument air-driven pneumatic controllers consistent with the CD. Each of these requested requirements reflect requirements the facility was already subject to under the CD. Among other things, the CD required (unless technically infeasible) high-bleed pneumatic controllers be replaced with low-bleed or no bleed pneumatic controllers at all existing Uinta Basin facilities, which includes Ouray, and that oxidation catalysts be installed and operated on each existing reciprocating internal combustion engine (RICE) operating in the Uinta Basin that is rated at or above 500 horsepower (hp). Ex. 1 § IV.A., ¶¶ 9 - 11; § IV.D., ¶¶ 49 - 57; § IV.E., ¶¶ 63 - 65.

When the MNSR permit is effective, the permit limitations will enhance the legal and practical enforceability of existing requirements from the CD that limit emissions from Ouray below levels which would trigger applicability of other Clean Air Act (CAA) requirements, such as the Prevention of Significant Deterioration (PSD) Permit Program at 40 CFR part 52 and Part 71. The EPA has determined that issuance of this MNSR permit will not contribute to National Ambient Air Quality Standards (NAAQS) violations or have potentially adverse effects on ambient air quality.

 Testing and Monitoring Requirements
            
             The Permittee shall measure the barrels of natural gas condensate and produced water stored in the tanks each time the liquids are unloaded from the storage tanks using process flow meters and/or sales records. At the end of each calendar month, the total barrels of natural gas condensate and produced water stored in the tanks shall be divided by the number of days in that month to calculate a daily average.
             
             The Permittee shall perform weekly auditory, visual, olfactory (AVO) inspections of tank thief hatches, covers, seals, pressure relief valves and the closed vent system, to ensure proper condition and functioning. The weekly inspections shall be performed while the natural gas condensate and produced water storage tanks are being filled. If any of the components are not in good working condition, they must be repaired within 15 days of identification of the deficient condition.
              
             The Permittee shall perform monthly visual inspections of the peak pressure and vacuum values in each tank and the closed-vent system to ensure that the pressure and vacuum relief set points are not being exceeded in a way that has resulted, or might result, in venting of emissions and possible damage to equipment, and to ensure that the closed-vent system operates with no detectable emissions. Monthly visual inspections shall be conducted as follows:

             The monthly inspections shall be performed using an optical gas imaging instrument and while the natural gas condensate and produced water storage tanks are being filled;
             If any detectable emissions or visible smoke emissions are detected using the optical gas imaging instrument, the Permittee shall take the following actions, as applicable:
                  
 The Permittee shall demonstrate that the natural gas condensate and produced water storage tanks and the closed-vent system operate with no detectable emissions using the procedures specified in EPA Method 21 at 40 CFR part 60, appendix A. A potential leak is determined to operate with no detectable emissions if the VOC concentration value measured by the Method 21 detection instrument is less than 500 parts per million volume (ppmv); 
                        
 If the closed-vent system or flare fail the detectable emissions or visual emissions test, the Permittee shall follow the manufacturer's, vendor's or Permittee's repair instructions to return the emissions source to compliant operation. All repairs and maintenance activities shall be recorded in a maintenance and repair log and shall be made available for inspection;
 Upon return to operation from any repair and maintenance activity, the closed-vent system or flare shall pass a Method 21 or Method 22 test, as applicable;
 If the closed-vent system or flare fail a follow up Method 21 or Method 22 test, the Permittee shall repeat the procedures in paragraphs (A) through (C) of this section, as applicable, until the closed-vent system or flare passes a follow up test; and
 The monthly VOC emissions calculations required in this permit shall account for the time periods between each failed detectable emissions or visible emissions test, as applicable, and subsequent compliant tests, assuming the emissions were uncontrolled.
             
             The Permittee shall monitor the operation of the flare to confirm proper operation and demonstrate compliance with the VOC control efficiency requirements of this permit as follows:
 
 Continuously monitor the flare operation using a malfunction alarm and remote notification system for failures, and checking the system for proper operation whenever an operator is on site at least weekly;
 Continuously monitor all variable operational parameters specified in the manufacturer's written operating instructions and procedures;
 Respond to any observation of improper monitoring equipment operation or any alarm of pilot flame failure and ensure that monitoring equipment is returned to proper operation and/or the pilot flame is relit as soon as practically and safely possible after an observation or an alarm sounds;
 Perform monthly visual inspections of the flare to ensure it operates with no visible smoke emissions. Monthly visual inspections shall be conducted as follows: 
                  
                   The monthly inspections shall be while the natural gas condensate and produced water storage tanks are being filled;
                   If any visible smoke emissions are detected the Permittee shall take the following actions:
                        
                         The Permittee shall demonstrate that the flare operates with no visible emissions, except for periods not to exceed a total of 2 minutes during any hour using the procedures specified in EPA Method 22 at 40 CFR part 60, appendix A. The observation period shall be 1 hour;
                         If the flare fails the visual emissions test, the Permittee shall follow the manufacturer's, vendor's or Permittee's repair instructions to return the flare to compliant operation. All repairs and maintenance 
                              
                              activities shall be recorded in a maintenance and repair log and shall be made available for inspection;
                         Upon return to operation from any repair and maintenance activity, the flare shall pass a Method 22 test; and
                         If the flare fails a follow up Method 22 test, the Permittee shall repeat the procedures in paragraphs (I) through (III) of this section until the flare passes a follow up test.
            
             The monthly VOC emissions calculations required in this permit shall account for the time periods between each failed detectable emissions or visible emissions test, as applicable, and subsequent compliant tests, assuming the emissions were uncontrolled.
            
             Where sufficient to meet the monitoring requirements in this section, the owner or operator may use a SCADA system to monitor and record the required data in paragraphs (a) through (d).

II. General Provisions

A.	Conditional Approval  

Pursuant to the authority of 40 CFR 49.151, the EPA hereby conditionally grants this permit to construct. This authorization is expressly conditioned as follows:

 Document Retention and Availability: This permit and any required attachments shall be retained and made available for inspection upon request at the location set forth herein.

 Permit Application: The Permittee shall abide by all representations, statements of intent and agreements contained in the application submitted by the Permittee. The EPA shall be notified 10 days in advance of any significant deviation from this permit application as well as any plans, specifications or supporting data furnished. 

 Permit Deviations: The issuance of this permit may be suspended or revoked if the EPA determines that a significant deviation from the permit application, specifications and supporting data furnished has been or is to be made. If the proposed source is constructed, operated or modified not in accordance with the terms of this permit, the Permittee will be subject to appropriate enforcement action.

 Compliance with Permit: The Permittee shall comply with all conditions of this permit, including emission limitations that apply to the affected emissions units at the permitted facility/source. Noncompliance with any permit term or condition is a violation of this permit and may constitute a violation of the CAA and is grounds for enforcement action and for a permit termination or revocation.

 Fugitive Emissions: The Permittee shall take all reasonable precautions to prevent and/or minimize fugitive emissions during the construction period.

 NAAQS and PSD Increments: The permitted source shall not cause or contribute to a NAAQS violation or a PSD increment violation.

 Compliance with Federal and Tribal Rules, Regulations, and Orders: Issuance of this permit does not relieve the Permittee of the responsibility to comply fully with all other applicable federal and tribal rules, regulations and orders now or hereafter in effect.

 Enforcement: It is not a defense, for the Permittee, in an enforcement action to claim that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this permit.
      
 Modifications of Existing Emissions Units/Limits: For proposed modifications, as defined at 40 CFR 49.152(d), that would increase an emissions unit allowable emissions of pollutants above its existing permitted annual allowable emissions limit, the Permittee shall first obtain a permit modification pursuant to the MNSR regulations approving the increase. For a proposed modification that is not otherwise subject to review under the PSD or MNSR regulations, such proposed increase in the annual allowable emissions limit shall be approved through an administrative permit revision as provided at 40 CFR 49.159(f).

 Relaxation of Legally and Practically Enforceable Limits: At such time that a new or modified source within this permitted facility/source or modification of this permitted facility/source becomes a major stationary source or major modification solely by virtue of a relaxation in any legally and practically enforceable limitation which was established after August 7, 1980, on the capacity of the permitted facility/source to otherwise emit a pollutant, such as a restriction on hours of operation, then the requirements of the PSD regulations shall apply to the source or modification as though construction had not yet commenced on the source or modification.

 Revise, Reopen, Revoke and Reissue, or Terminate for Cause: This permit may be revised, reopened, revoked and reissued or terminated for cause. The filing of a request by the Permittee, for a permit revision, revocation and reissuance, or termination, or of a notification of planned changes or anticipated noncompliance does not stay any permit condition.
