Topic: Clean Air

Humans, plants, and animals all need clean air to survive. A variety of human activities can add pollutants to the air and harm our health. DNREC has several programs to help ensure Delaware’s air meets State and Federal Air Quality Standards. These standards protect public health and the environment.

DNREC staff track air quality and issue air quality forecasts and warnings. They monitor industries and other sources of air pollution and work with businesses and citizens to reduce air pollution. DNREC also regulates activities such as open burning and the handling of asbestos.

The links that follow are to a collection of pages on the old DNREC website (and a few other agencies) that relate to this topic.  As the new DNREC website is built-out, these will change to links to the new site.  Things will look a little mixed for a while, but we’ll always try to point you to useful information.

What’s Hot

Delaware’s Petitions for Clean Air Delaware submitted four petitions to the Environmental Protection Agency (EPA) under the Clean Air Act asking that agency to require sources in upwind states to control their air pollution which blows across state lines and into Delaware. The state has asked that those states control their sources at amounts that would not violate the good neighbor provisions of the Act. On June 8, 2018, the EPA announced its intent to deny all four of Delaware’s petitions.

DNREC held a public meeting on the petitions on July 16, in Newark, to enable Delawareans to express their opinion about the EPA proposal to deny the state’s petitions. Submit your thoughts through the Governor’s website through July 23.

Be Aware

What is the Air Quality forecast? DNREC works with meteorological experts to forecast Air Quality in Delaware. These experts look at regional and local conditions and issue daily air quality forecasts. The forecasts updates on ozone and particulate concentrations.

What are the latest readings? DNREC maintains a network of air quality monitoring stations across the state and offers real time air quality data. DNREC also offers pollen and mold counts during allergy season (March 1st – October 15th).

What’s happening with pollution sources? DNREC provides annual reports, the Toxics Release Inventory, of pollution releases to the air as well as to the land and water.
