The Environmental Protection Agency (EPA) is announcing a proposed Settlement Agreement concerning challenges by the State of Wyoming and PacifiCorp related to the EPA's ruling on Wyoming’s Regional Haze State Implementation Plan (SIP). In 2014, both parties filed reviews against EPA's final rule, which partially disapproved the SIP's elements and created a Federal Implementation Plan (FIP) to cover these gaps. The proposed agreement aims to resolve disputes over nitrogen oxide requirements at PacifiCorp's Wyodak unit, with specific actions outlined if the agreement is accepted. The EPA is seeking public comments on this proposed agreement until February 3, 2021.

The Environmental Protection Agency (EPA) is proposing to approve West Virginia's plan to address visibility issues caused by air pollution in national parks and wilderness areas, known as Class I areas. This decision reverses a previous proposal to disapprove the state's plan. The approval is based on West Virginia's measures to control emissions and the conclusion that no further actions are needed to improve visibility during the specified period. The EPA's decision reflects a change in their policy, suggesting that if current air conditions are below a certain improvement mark, states are meeting progress requirements.
