The Regulatory Unit is responsible for regulating storage, treatment, transport, and disposal of hazardous waste and used oil for all hazardous waste handlers in the State of Montana. In addition, the Unit provides technical assistance to, and conducts inspections of, hazardous waste generators of all sizes throughout Montana. The State is divided into two coverage areas with one regulator assigned to each area. Persons who transport hazardous wastes are required to notify the DEQ and to obtain an identification number. Persons who generate hazardous waste (with certain exceptions) are required to maintain an annual generator registration and to pay a registration fee each year, in addition to obtaining an EPA (U.S. Environmental Protection Agency) identification number.
A permit from the DEQ is required to construct or operate a hazardous waste treatment, storage, and disposal facility in the State. Permits are issued to ensure hazardous waste facilities are operated in a manner that protects human health and the environment. Permits also require historical releases be cleaned up appropriately. This entails facility soil and groundwater investigations, risk assessments, and review of potential clean up remedies.
