The U.S. Environmental Protection Agency (EPA) is proposing approval of revisions to the New Mexico Regional Haze plan to address nitrogen oxide emissions (NOx) from the coal-fired San Juan County power plant.
EPA, New Mexico and Public Service Co. of New Mexico (PNM) collaborated to develop the regional haze plan, which is an alternative to EPA’s federal implementation plan. The new plan allows EPA to withdraw the FIP while still reducing carbon dioxide (CO2) emissions, water usage and wastewater generation.
PNM plans to retire two units at the San Juan power plant, reducing its output by 340 MW. The company will install NOx reduction technology on the other two units and will work with Aconex on the $100 million project.
Publication of the EPA proposal in the Federal Register begins a 30-day public comment period.
