The Environmental Unit (EU) works within the Planning Section under the Incident Command System and has a key responsibility to ensure that any response to an incident addresses environmental, cultural, and socioeconomic priorities. The EU identifies sites for protection and recommends procedures to minimize impacts from a spill and from response operations. The EU provides critical input the planning process and formulation of incident action plans for operations through field assessments, recommendations for treatment strategies, response monitoring, sampling and data management, and preparation of plans for activities requiring permits. This training program provides participants with an in-depth review of roles, responsibilities, and tools for implementing and working within the EU.
