Site Assessment and Community-Stakeholder Engagement

Part of the MEHEA program strategy to address public health threats from environmental waste includes conducting hazardous waste site assessments at National Priority List (NPL) and state-funded cleanup sites throughout the state. Annually, the MEHEA program prioritizes work at hazardous sites with our ATSDR Technical Project Officer, Montana Department of Environmental Quality (DEQ), U.S. Environmental Protection Agency (EPA), and local agencies. You can review current and past program activities below.
