The Environmental Protection Agency (EPA) is approving part of Virginia's State Implementation Plan (SIP), which includes negative declarations for certain Control Techniques Guidelines (CTG) and Alternative Control Techniques (ACT) for ozone standards. These declarations show that there are no sources in Northern Virginia subject to these guidelines, including for the 2016 Oil and Gas industry CTG. The approval confirms that Virginia meets the requirements of the Clean Air Act for these guidelines, and it does not conflict with any state or federal laws or regulations. This action simply acknowledges Virginia's compliance and does not impose new regulations.
Simple Explanation
The EPA said Virginia is doing a good job keeping the air clean because they checked and found no pollution sources in certain areas that would require special plans. This means Virginia follows the air-cleaning rules without needing to make new ones.
