SO2 annual report for reviewSO2 annual report for review
The draft SO2 Annual Report is available for public inspection and comment through June 25, 2021. The report contains an annual comparison of SO2 emissions from four applicable sources in counties that were designated as attainment/unclassifiable for the 2010 primary SO2 National Ambient Air Quality Standard (NAAQS) based on modeling submitted by DEQ. View the draft report. 
New permitting guidance available to determine the following:
  • Representative Sampling: representativeness of sampling used to calculate emissions from oil and gas facilities. Form 100-702 is now required for all oil and gas permit applications.
  • Effluent Water Separator: if a storage vessel qualifies as a vessel operating as an effluent water separator or if the vessel is simply a storage tank.
  • Produced Water: for tanks storing produced water and condensate/oil, updated emission calculation requirements for applications submitted on or after April 15, 2021.

What is Air Quality?

The amount of pollution in the air from all sources – natural and human – defines the quality of the air we breathe. Air pollution isn’t limited to our cities; it can blow into any part of Oklahoma from neighboring states.

Bad air quality can affect everybody’s health. It can have direct effects on the lungs, and it can worsen an existing condition, such as asthma. Some people are more sensitive to air pollution than others. These include young children who are growing rapidly and older adults who have reduced immune systems.

Poor public health also incurs economic costs for society, e.g., increased healthcare costs and loss of working days. A clean environment makes Oklahoma an attractive place to live, work and play: something we can all be proud of.
