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.

Obtaining Assistance

Persons conducting or coordinating environmental site assessments and investigations should be familiar with applicable federal, state and local environmental laws and regulations. Additionally, knowledge of hydrogeologic, environmental engineering, manufacturing processes, chemistry and biological processes many be necessary. A multi-disciplinary team of experienced professionals may be needed to assess or investigate projects at high risk for hazardous materials impacts. This team may include structural and environmental engineers, geologists, hydrogeologists, biologists, chemists, toxicologists, and/or industrial hygienists. The team will identify major concerns and any corrective or preventative activities required to resolve them. These activities may include health and safety training, acquisition of licenses and permits, and/or coordination with regulatory agencies.

Some districts may already have in-house staff with the knowledge, education, and experience necessary to perform or coordinate corrective or preventative activities. However, a district may also opt to use environmental consultants on statewide contract with the Texas Department of Transportation (TxDOT) to perform this work. The services of environmental specialty contractors may also be required. District personnel can contact ENV for assistance.

TxDOT employees can obtain additional information on occupational safety, health, and training in the TxDOT Occupational Safety Manual, particularly the chapters on hazardous materials, safety rules, and standards.
