Our mission is to maintain the purity of Missouri's air to protect the health, general welfare and property of the people. The Air Pollution Control Program has more than 6 million customers. Whether an urban citizen or someone far removed from other people, everyone who lives in Missouri needs and deserves clean air. This home page will help you to find out more about the services available to help us protect air quality.

As part of the Division of Environmental Quality, the Air Pollution Control Program works diligently to raise awareness about air quality and air pollutants. Missouri Skies Now and Then offers a glimpse into some of the progress we have made towards better air in Missouri.

Comment Period Open for Periodic Rule Review

State legislation passed in 2012 requires the review of all agencies’ rules every five years. The Missouri Department of Natural Resources and three other departments currently are reviewing their rules. The public may comment on the rules for 60 days, through Aug. 31, 2016, as specified in state law 536.175. Click comment process to learn more about the periodic rule review. Click Department of Natural Resources rules to view all department rules. Please see Division 10 for rules relevant to the Air Pollution Control Program.

The department will use the public comments to prepare a report detailing which rules are necessary or duplicative and which need to be amended or rescinded. The department must complete the report by June 30, 2017; it will appear on the department’s website.

The Missouri Department of Natural Resources has 614 rules, and 101 of them apply to the air program's work in Missouri.

Seasonal Tips for Saving Money and Lowering Air Pollution

You can help clean the air and save some money in the process!

Install a programmable thermostat: Cooling and heating your home accounts for almost half of your energy bill – about $1,000 a year! One of the easiest ways you can save energy in your home and help reduce carbon pollution is by installing a programmable thermostat. For example:

  • Set your thermostat for 78 degrees during the summer (or 68 degrees during winter) when you are awake and at home.
  • Decide on at least an eight-hour period per day when you can set your thermostat 10 − 15 degrees warmer during the summer (or 10 − 15 degrees cooler during the winter).

Check your HVAC filter every month, particularly during winter and summer when you're frequently using the system. Change the filter if it looks dirty or every three months at a minimum. Dirty filters slow down the air flow making the system work harder to keep you cool or warm which then increases your energy bill.
