Contact Info

The purpose of the Los Alamos County Local Emergency Planning Committees (LEPC) is to enhance Los Alamos County’s preparedness and response to hazardous materials incidents by involving the government, private business, non-profit organizations and citizens in planning and preparing for such an incident. The Los Alamos County LEPC will also act as an advisory committee to the Los Alamos County Government in regards to emergency preparedness and response for hazardous materials and will fulfill any and all additional requirements articulated under the Emergency Planning and Community Right to Know Act (EPCRA).

The LEPC is comprised of members representing: Elected County and Local Officials, Law Enforcement, Emergency Management, Firefighting, Emergency Medical Services, Broadcasting and/or print media, Community groups, and Operators and Owners of facilities subject to the requirement of SARA Title III Act. Visit the United States Environmental Protection Agency (EPA).

The EPRCA was enacted by Congress in 1986 Congress to ensure that government and the public had access to the information needed to plan for chemical emergencies. EPCRA required each state to establish a State Emergency Response Commission (SERC), to create local emergency planning districts, and to establish an LEPC in each district. In addition to fulfilling its role with respect to hazardous chemicals, the Los Alamos County LEPC has expanded its role with respect to hazardous chemicals, the Los Alamos County LEPC has expanded its scope to preparedness for all hazards and all communities.
