Circuit declined to vacate the EPA’s 2016 rule to update its Cross-State Air Pollution Rule (CSAPR). However, the court did remand one […]

Additional Good Neighbor Requirements Unnecessary, Says EPA

Based on “additional information and analysis,” the EPA is proposing to determine that its Cross-State Air Pollution Rule (CSAPR) Update for the 2008 ozone National Ambient Air Quality Standards (NAAQS) (October 26, 2016, Federal Register (FR)) satisfies the Agency’s obligation to issue federal implementation plans (FIPs) for 20 states to address air pollution from those […]

Good-neighbor Rule Updated to 2008 Ozone NAAQS

In a final action, the EPA has updated its 2011 Cross-State Air Pollution Rule (CSAPR) with respect to the 2008 ozone National Ambient Air Quality Standards (NAAQS). According to the Agency, the action constitutes the first time the EPA has updated an existing program to address interstate transport of air pollution under a new air […]

Interstate Pollution FIP Proposed

The EPA has released a preproposal for a Federal Implementation Plan (FIP) to carry out its Cross-State Air Pollution Rule (CSAPR) in states that do not have approved state implementation plans (SIP) showing how they will comply with the CSAPR.
