Answer: The DAS Construction Services Environmental Planning and Energy Unit should be contacted when a project has complex or multiple environmental permits, when there will be significant involvement with regulatory agencies, when soil and/or groundwater investigations must be performed, when underground storage tanks require removal and/or installation, and/or when property transfers are being discussed. Identification of permitting and environmental issues early in a project will avoid delays and allow for the scheduling of the permit process and environmental investigations into the overall project schedule. To assist the Design Consultant, DAS Construction Services has the 3030 Checklist for Permits, Certifications and Approvals which has to be reviewed, completed, revised, and submitted to the DAS Project Manager at each design phase with a copy to the DAS Environmental Planning Unit.
