The Environmental Affairs Division (ENV) is responsible for coordinating hazardous materials management issues and serves as the initial point of contact for each district.

Each district is responsible for ensuring coordination of hazardous material issues during planning and project development. To facilitate this coordination, the district should consider assigning a single hazardous materials coordinator for project development or a hazardous materials team consisting of members from all functional areas. The assignments of district personnel and/or section responsibilities rest with the district.
