Regional Haze overview

The federal Clean Air Act requires the U.S. Environmental Protection Agency (EPA) to reduce human-caused visibility impairment at certain federal public lands around the country. To fulfill this mandate, EPA adopted a regulation known as the Regional Haze Rule. It aims to reduce visibility-obscuring pollutants caused by human sources over a widely scattered area. The Rule says that states must submit plans to EPA about once every ten years, demonstrating how a state will make what the rule calls "reasonable progress" over time toward visibility improvement. Reasonable progress means gradual reductions in human emissions of substances known to cause visibility issues at the national parks and wilderness areas protected by the Rule.  

The City of Albuquerque Environmental Health Department (EHD), Air Quality Program, is cooperating with the New Mexico Environment Department (NMED) to develop a statewide Regional Haze plan. EHD is developing the portion of the statewide plan that will cover Albuquerque and Bernalillo County. NMED will develop the parts covering the rest of the state. EHD must submit its proposed local element of the plan for consideration by the Albuquerque - Bernalillo County Air Quality Control Board. 

On the road to that milestone, EHD and NMED are seeking public input. For details of the statewide Regional Haze planning process, go to NMED's Regional Haze web page. It describes how the Regional Haze Rule works, provides links to extensive background information, and enables sign-up for email updates on New Mexico's statewide Regional Haze effort.
