About the Program

Responsibilities established by law

Federal law Hazardous waste is considered any waste that can be dangerous or potentially harmful to human health or the environment. The Hazardous Waste program originated in 1965 with the federal Solid Waste Disposal Act. In 1976, the United States passed the Resource Conservation and Recovery Act, commonly known as RCRA, which split Hazardous Waste and Solid Waste into two distinct areas. This law gave U.S. EPA greater ability to regulate hazardous waste from “cradle-to-grave.”

Local mandates In December 1998, Public Law 24-64 created the Hazardous Waste Management Program. This program was created to protect Guam’s environment from potentially dangerous and harmful chemicals. This includes liquids, storage facilities for hazardous waste and other areas. Many of the areas this program focuses on match federal mandates established for other states and territories, for example working with Underground Storage Tanks (UST)s or shipping hazardous materials.

In the field

This program does routine inspections of Underground Storage Tanks (USTs) and inspections of other permitted facilities. The Hazardous Waste Program also responds to hazardous waste spills and other emergency situations.

Elements of the Program


The Program is responsible for permitting hazardous waste collection and treatment, storage, and disposal facilities. In addition, the Hazardous Waste Program is responsible for inspecting, monitoring compliance, enforcement and overseeing corrective action for all hazardous waste-related activities. This includes underground storage tanks, CERCLA, TSCA (specifically PCBs) and emergency response (Public Record Post Date: 07/7/2016).

Underground Storage Tanks (USTs) – AS OF July 1, 2019

Maintaining Underground Storage Tanks is a key component to protecting the environment from hazardous waste. This program publishes information about USTs located in Guam.
