The Unified Program is a suite of six state hazardous materials management programs consolidated and administered by a local Certified Unified Program Agency (CUPA). The CUPA inspects businesses or facilities that handle or store hazardous materials; generate and/or treat hazardous waste; own or operate underground storage tanks; store petroleum in aboveground tanks over State thresholds; and store Federal regulated hazardous materials over State thresholds. The inspections determine compliance with the California Health and Safety Code, California Code of Regulations, and the Code of Federal Regulations. The CUPA Program achieves compliance through education, community and industry outreach, inspections and enforcement.

The Aboveground Petroleum Storage Act (APSA) applies to owners and operators with a total storage capacity, at a single location or site, of 1,320 gallons or more of petroleum in aboveground tanks and containers that are 55-gallons in size and greater. The purpose of the APSA program is to prevent a spill of petroleum from reaching navigable surface water and/or ground water. This is accomplished through a comprehensive inspection program to verify that tank facilities have prepared and are implementing a federal Spill Prevention, Control, and Countermeasure (SPCC) Plan.
The California Accidental Release Prevention (CalARP) program applies to facilities that store or use regulated (often referred to as extremely hazardous) substances above regulatory (planning threshold) quantities. The purpose of the Cal ARP Program is to reduce the likelihood and severity of consequences of extremely hazardous materials releases. This is accomplished by requiring regulated facilities to submit a Risk Management Plan (RMP), review of the RMP and facility inspections.
The Business Plan program applies to facilities that handle, store or use hazardous materials over certain amounts called threshold quantities. The purpose of this program is to prevent and minimize damage to workers, the public, and enhance public safety by training facility personnel to respond adequately to a release or threatened release of a hazardous material. Additionally, the Business Plan program is used satisfy federal and state Community Right-To-Know laws by providing detailed information about hazardous material stored a facility for use by emergency responders, planning officials and the community. These purposes are realized through a comprehensive program of Business Plan review, facility inspection, assistance to regulated businesses, enforcement and public education.
The Hazardous Waste Generator Program ensures the safe and legal handling, storage, and disposal of hazardous waste. The purpose of this program is the protection of public health and the environment from exposure to hazardous wastes by regulation of the businesses and industries that generate hazardous waste. This is accomplished through a comprehensive program of inspection, complaint investigation, and assistance to industry, enforcement and public education.
The Hazardous Waste Tiered Permit Treatment Program ensures the safe and legal treatment of hazardous waste. The purpose of this program is the protection of public health and the environment from exposure to hazardous wastes by regulation of the businesses and industries that treat hazardous waste. This is accomplished through a comprehensive program of requiring permits for facilities that treat hazardous waste, reviewing treatment permits and inspection of the treatment process.
The Underground Storage Tank (UST) program applies to owners and operators of USTs used for the storage of hazardous substances. The majority of these USTs contain petroleum products. The purpose of the UST Program is to protect public health, the environment and groundwater. This goal of this program is to ensure that businesses and facilities with ongoing UST operations are properly permitted and meet the monitoring requirements applicable to their type of system. This is accomplished during plan check and inspection activities. Each UST facility is inspected annually.
Wells drilled for the purpose of monitoring environmental impacts are permitted separately from drinking water wells. These installations include geotechnical bores, groundwater sampling bores, and contaminated soils and groundwater monitoring wells.
