Local Emergency Planning Committee

LEPC Scope


The Maricopa County Local Emergency Planning Committee (“MC-LEPC”) is a committee composed of community volunteers from elected positions, the emergency services field, media agencies, community groups, and industry; appointed by the Arizona State Emergency Response Commission (“AzSERC”), which also maintains oversight authority over the committee. The MC-LEPC is tasked as a community body to oversee local compliance with the Emergency Planning and Community Right to Know Act (“EPCRA”), 42 U.S.C. § 11001 – 11050. EPCRA requires all facilities that have hazardous substances at or in excess of certain amounts to provide the Arizona Department of Environmental Quality (“ADEQ”) with the identity of the facility representative who must provide that facility’s emergency plan and who will also participate in the emergency planning process. Among the duties of these facilities is the duty to submit a list and inventory of its hazardous substances that are present at or above certain threshold quantities and prepare and file with ADEQ and the MC-LEPC an emergency response plan as required in statute.

EPCRA requires the MC-LEPC to prepare and review an emergency response plan to address emergencies due to releases of hazardous substances from facilities or transportation vehicles within Maricopa County. Additionally, the MC-LEPC will either make available to the public, upon request, the relevant material safety data sheets of those chemicals or direct the request to the facility.

EPCRA does not require those who do not produce, use, or store hazardous chemicals to report releases of hazardous substances. Additionally, under EPCRA, the MC-LEPC is not a response, investigative, or enforcement body. Any reports of violations of EPCRA are forwarded to the ADEQ for investigation and disposition. Any life-threatening release of hazardous chemicals should be reported immediately to emergency responders by calling 911. All other reports of non-life threatening hazardous chemical releases or EPCRA violations by the general public should be directed to the ADEQ.

Questions and concerns from the public are welcome, and the committee will respond to matters that are within the scope of its authority. The MC-LEPC believes that the community will benefit when there is a transparent and mutually respectful relationship with its community partners. Communication between citizens, business, and government enhances the protection of the community and the environment.
