The period for written public comments on three air pollution control regulations has been extended until Feb. 17. Arkansas environmental officials announced the extension on Wednesday.
Officials say the proposed changes are necessary in order to adopt the EPA's National Ambient Air Quality Standards for things like lead, nitrogen dioxide, sulfur dioxide and ozone.
The proposed changes will give the state the authority to implement air pollution control programs and to issue permits.
During the public comment period, the Arkansas Department of Environmental Quality will take comments on when an analysis would be required to evaluate impacts on the air standards during the permitting process.á
