10 GCEAG - September 9, 2010 Emissions Events 30 TAC § Emissions Event Reporting and Recordkeeping Requirements 30 TAC § Emissions Event Reporting and Recordkeeping Requirements Reportable Quantities (within any 24 hr period) Reportable Quantities (within any 24 hr period) Typically 5,000 lbs for natural gas Typically 5,000 lbs for natural gas 100 lbs if H 2 S or mercaptans 100 lbs if H 2 S or mercaptans If RQ exceeded, must be reported within 24 hours (reportable) If RQ exceeded, must be reported within 24 hours (reportable) If not, final in-house record must be completed within 14 days (non-reportable) If not, final in-house record must be completed within 14 days (non-reportable)

11 GCEAG - September 9, 2010 Stack Testing

12 GCEAG - September 9, 2010 Stack Testing Oil & gas production sites often include multiple combustion sources which may require stack testing Oil & gas production sites often include multiple combustion sources which may require stack testing 30 TAC 117, Subchapter D 30 TAC 117, Subchapter D Applies to minor, stationary sources of NOx located in ozone non-attainment areas 40 CFR 60 Subpart JJJJ – Standards of Performance for Stationary Spark Ignition Internal Combustion Engines 40 CFR 60 Subpart JJJJ – Standards of Performance for Stationary Spark Ignition Internal Combustion Engines 40 CFR 63 Subpart ZZZZ – National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines 40 CFR 63 Subpart ZZZZ – National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines

13 GCEAG - September 9, 2010 Stack Testing To determine whether an engine must be stack tested, the following information is needed: Type of Compression Type of Compression Horsepower Rating Horsepower Rating Manufacture Date Manufacture Date Type of Burn (Rich v. Lean) *these numbers differ for the EPA vs. TCEQ Type of Burn (Rich v. Lean) *these numbers differ for the EPA vs. TCEQ Is the Engine in question Portable, Stationary, or Emergency? Is the Engine in question Portable, Stationary, or Emergency? Is the Engine located in an Attainment or non-Attainment County? Is the Engine located in an Attainment or non-Attainment County?
