1 OIL AND GAS AIR QUALITY AUTHORIZATIONS IN TEXAS Kristyn Bower and David Reyna Air Permits Division Texas Commission on Environmental Quality

2 TODAY’S TOPICS  Terminology  Permitting Options  Oil and Gas PBRs  Oil and Gas Standard Permit Options

3 TERMINOLOGY Pollutants of Concern  VOCs  H 2 S  CO  NO x  SO 2  PM 10 and PM 2.5

4 Facility –stationary equipment that emits pollutants  Engines  Tanks  Flares  Separators  Dehydrators TERMINOLOGY

5 Site – a group of oil and gas facilities at a property  Common control  Equipment that relies on each other  Within ¼ mile TERMINOLOGY

6 Produced water tank Oil tank Gunbarrel Separator Wellhead ANDY’S SITE

7 TERMINOLOGY Receptor  Residence or other structure which is not used only by the O&G owner/operator  Recreational Area

8 Andy’s PropertyNathan’s Property Nathan’s House Andy’s House Mechanic Shop ANDY AND NATHAN’S PROPERTY

9 OIL AND GAS PERMITTING OPTIONS De Minimis Permit by Rule Standard Permit State Permit NNSR and PSD Increasing Levels of Emissions De Minimis Permit by Rule Standard Permit State Permit NNSR and PSD

10 DE MINIMIS Pipeline isolation valve sites meeting certain criteria

11 OIL AND GAS PERMITTING OPTIONS De Minimis Permit by Rule Standard Permit State Permit NNSR and PSD Increasing Levels of Emissions De Minimis Permit by Rule Standard Permit State Permit NNSR and PSD

12 PERMITS BY RULE Must meet all conditions exactly Emission limits in TAC §106.4(a)(1)  25 tpy of VOCs/SO2  250 Nox,CO  25tpy H2S  PM/PM10and PM2.5 Meet all other applicable federal, state, and local requirements

13 PBR OPTIONS – LOCATION In Barnett Shale counties New - 30 TAC § (a)-(k) Existing – 30 TAC § (l) Not in Barnett Shale counties New & Existing – 30 TAC § (l) May voluntarily register under § (a)-(k)

14 BARNETT SHALE COUNTIES

15 § (l) – SWEET  No registration required  Meet §106.4 limits  Various facilities included  Vent height applicable if handling a sulfur compound  Flares follow §  Compressors follow §

16 § (l) – SOUR  24 ppmv of H 2 S or greater = TCEQ sour  Registration required  ¼ mile distance required  4.0 lb/hr limit of sulfur compounds (not including sulfur oxides)  Vent height based on sulfur compound limit

17 § (a)–(k)  Notification and registration are required to be submitted using the ePermits system  Notification - Prior to construction or implementation of changes  Registration  Level 1 - Within 180 days from start of operation  Level 2 - Within 90 days from start of operation

18 § (a)–(k) PBR Level 1 Emission Limits Air ContaminantSteady-state lb/hr < 30 psig periodic lb/hr up to 150 hr/hr ≥ 30 psig periodic lb/hr up to 300 hr/yr Total tpy Total VOC15 Total crude oil or condensate VOC Total natural gas VOC ,500 Benzene Hydrogen sulfide Sulfur dioxide Nitrogen oxides Carbon monoxide45100 PM 2.5 /PM

19 § (a)–(k) PBR Level 2 Emission Limits Air ContaminantSteady- state lb/hr < 30 psig periodic lb/hr up to 150 hr/hr ≥ 30 psig periodic lb/hr up to 300 hr/yr Total tpy Total VOC25 Total crude oil or condensate VOC Total natural gas VOC ,500 Benzene Hydrogen sulfide Sulfur dioxide Nitrogen oxides Carbon monoxide57250 PM PM

20 § (a)–(k) IMPACTS  Emission impacts tables  Screening modeling  Dispersion modeling Air contaminantlb/hr Benzene0.039 Hydrogen sulfide0.025 Sulfur dioxide2 Nitrogen oxides4

21 OTHER PBRS RELATED TO OIL AND GAS  Salt Water Disposal (petroleum) §  Temporary Oil and Gas Facilities (§ )  Air PBR : Pipeline Metering, Purging, and Maintenance (§ )  Stationary Engines and Turbines (§ )  Flares (§ )

22 PERMIT BY RULE GUIDANCE HELPFUL LINKS  Federal Standards Applicability Table  Emissions Calculations Spreadsheet  Representative Gas and Liquid Analysis  Control Device Charts

23 OIL AND GAS PERMITTING OPTIONS De Minimis Permit by Rule Standard Permit State Permit NNSR and PSD Increasing Levels of Emissions De Minimis Permit by Rule Standard Permit State Permit NNSR and PSD

24 STANDARD PERMIT OPTIONS Standard permit under §  “Old Standard Permit” Non-rule standard permit  Applies to new projects and dependent facilities in the Barnett Shale counties  Sites in other counties can use it voluntarily

25 STANDARD PERMIT UNDER § “ OLD STANDARD PERMIT” Sour sites that can’t meet ¼ mile limit in § (l) VOCs are >25tpy VOCs must be speciated using E=L/K Calculation techniques, emissions summary tables, etc. – same as a PBR application

26 NON-RULE STANDARD PERMIT Notification & registration online – STEERS (ePermits) system Notify - Prior to construction or implementation of changes Register  Within 90 days from the start of operation Impacts – Same as § (a)-(k)

27 NON-RULE STANDARD PERMIT EMISSION LIMITS ContaminantSteady-state or < 30 psig (lb/hr) ( normal emissions) > 30 psig Periodic (lb/hr) (MSS, loading, etc) Total (tpy) Total VOC250 Total Crude Oil or condensate VOC Total natural gas VOC 7501,635 Benzene Hydrogen sulfide Sulfur dioxide Nitrogen oxides Carbon monoxide PM 10 /PM

28 OIL AND GAS PERMITTING OPTIONS De Minimis Permit by Rule Standard Permit State Permit NNSR and PSD Increasing Levels of Emissions De Minimis Permit by Rule Standard Permit State Permit NNSR and PSD
