Volkswagen Settlement

The Volkswagen (VW) Environmental Mitigation Trust Agreement allocated approximately $21 million for Oklahoma to reduce nitrogen oxide emissions from the transportation sector. DEQ has released a proposed VW Beneficiary Mitigaton Plan (BMP) for public review and comment by May 24, 2018. DEQ held a public meeting on May 8, 2018, which included a presentation on the BMP, opportunity for public comments, and a brief future outlook presentation. Visit DEQ's VW Settlement page for the draft plan, how to submit comments, and more.

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.

Why is it important?
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.  And a clean environment makes Oklahoma an attractive place to live, work and play: something we can all be proud of.

What does the Air Quality Division do?
Most importantly, we work to effectively protect the public health in Oklahoma.  We do this by:
