Source: EDF ran EPA’s CO-Benefits Risk Assessment (COBRA) screening model on this plant. COBRA is a screening tool, not a full air-quality model: it works at the county level and covers health impacts from fine particles and ozone only — it does not estimate health harms from mercury or other air toxics.
