Why it Matters
States rely on the Cross-State Air Pollution Rule (CSAPR) to protect their residents’ health by reducing smog and soot pollution from upwind sources in other states.
Lawsuits continue over the Federal Implementation Plan (FIP) and Phase 2 emissions budgets for CSAPR. Meanwhile, downwind states seek deeper cuts in pollution from out-of-state sources. Connecticut, Delaware, and Maryland have sued the Environmental Protection Agency (EPA) for failure to act on their section 126 petitions.
