Oil and Gas Representative Sample Guidance
AQD has developed a new guidance document and flowchart to streamline the review and acceptance of representative samples used for calculating emissions for Air Quality oil and gas facility permit applications. The guidance may be used now, but it will affect all permit applications submitted on or after March 15, 2021. DEQ Form #100-702 should be used in addition to current application forms to demonstrate the selected sample satisfies the criteria specified in the guidance.
Storage Tank Emissions Calculation Tool
Effective April 9, 2020, DEQ requests that applicants follow the updated calculation method provided in EPA’s AP-42 Chapter 7, Section 7.1- Organic Liquid Storage Tanks and discontinue use of TANKS 4.09d for permit application submissions. The new AP-42 method corrects errors for more accurate emissions estimates. The EPA webpage links to the final version of AP-42 Chapter 7, Section 7.1, a revision summary, a redline version highlighting (draft) changes, and responses to public comments.

DEQ has developed a new Storage Tank Emissions Calculation Tool for fixed roof and horizontal tanks. The tool is available online and downloadable for offline use. Floating roof tanks, landing, and cleaning calculations will be addressed in a future release. Sign up for the Air Permits mailing list to receive further updates.

AQD operates a dual permitting system — construction permits and operating permits — to control major and minor sources of air pollution.

  • A construction permit application is required before a new source is constructed or an existing source is modified.
  • AQD issues the construction permit after it is determined the source is designed to meet applicable rules and pre-construction requirements.
  • An operating permit is issued after construction is completed and demonstration is made that the source is capable of meeting applicable emissions limitations and air pollution control requirements.
