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 is presently working on a solution to help automate the calculations. Sign up for the Air Permits mailing list to receive notice when the tool is available.

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.
