  • Hazardous Waste Program

    The primary goal of the Pima County Department of Environmental Quality (PDEQ) Hazardous Waste Generator Program is to encourage the conservation of natural resources through resource recovery and waste minimization.  The State of Arizona first passed legislation regarding hazardous waste management in 1983.  The Arizona Department of Environmental Quality (ADEQ) obtained authorization to administer the hazardous waste management program in 1986.  PDEQ is delegated the functions, powers and duties to administer the Arizona hazardous waste generator program within Pima County through a delegation agreement between the two agencies.

    Hazardous waste exhibits properties that make it dangerous or potentially harmful to human health or the environment. Hazardous waste takes many physical forms and may be solid, semi-solid, liquid, or even contained gases.

    Overview

    PDEQ inspects all hazardous waste generators and hazardous waste complaints in Pima County for regulatory compliance.  Hazardous wastes are generated from many different chemical products and by many different types of businesses and activities.  Large generators tend to be manufacturers of various products while small generators are most often in the service industries.

    A facility’s hazardous waste generator status is determined on a monthly basis. If a hazardous waste generator’s status changes, the generator is required to comply with the respective regulatory requirements for that class of generators for the waste in that particular month. Although a generator may only be in a higher status for a single month, “episodic generators” must not only comply with the federal regulations for that period, but will be invoiced for the higher category’s annual generator registration fees as outlined in Title 7, Chapter 9 of the Pima County Code.

    IT IS CRITICAL THAT HAZARDOUS WASTE GENERATORS MAINTAIN DOCUMENTATION OF WHAT WASTES ARE GENERATED, AND WHEN THEY ARE GENERATED - EVEN IF THE FACILITY NORMALLY OPERATES AS A CONDITIONALLY EXEMPT SMALL QUANTITY GENERATOR (CESQG)!
