Effective November 2019, the TANKS emissions estimation software is now outdated and unsupported by EPA. Please use calculation methods provided in AP-42 Chapter 7, Section 7.1- Organic Liquid Storage Tanks (11/19) for working and breathing losses from volatile organic liquid storage tanks. The new AP-42 method corrects errors for more accurate estimates, , which DEQ used to develop a new Storage Tank Emissions Calculation Tool for fixed roof and horizontal tanks. More Information
In order to facilitate social distancing measures during this time and support industry in their continued compliance with environmental permitting and reporting requirements, AQD is encouraging our industry partners to submit permit applications, annual and semiannual reporting, and any questions through email to the permitting and compliance staff through the following contacts:

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.
