Environmental Permitting Unit
Determines permitting needs for Department projects and acquires permit approvals for State designed projects. Oversees and reviews consultant prepared applications for content and accuracy. Acts as main liaison with federal and State regulatory agencies such as U.S. Army Corps of Engineers (USACE), U.S. Environmental Protection Agency (EPA), and the Connecticut Department of Energy and Environmental Protection (CTDEEP). Assists in field work associated with wetland and water resource identification, habitat assessments and mitigation requirements.

Note: It is the preparer’s responsibility to use the most up-to-date forms when applying for a permit. Refer to DEEP LWRD Permit Applications webpage for the most recent versions of permit application forms.

Note: The CTDOT Environmental Permitting Unit has developed guidance materials to aid in the preparation of CTDOT applications for DEEP permits.  These guidance materials are available in the Permit Information subfolder to the ProjectWise 03.3 – Environmental Resources folder.

Engineering Project Coordination
The Bureau of Engineering & Construction’s Engineering Project Coordination (EPC) unit works in partnership with the Office of Environmental Planning (OEP). OEP and EPC work together toward the common goal of preserving environmental and cultural resources through the Department’s capital program.

EPC’s three key roles are:

  • Engineering/Environmental Representation - EPC works to help OEP and regulators better understand Department engineering requirements and processes. EPC simultaneously helps engineers understand the balance between design criteria, funding, schedules and environmental requirements/commitments.

  • New rules, regulations and procedures - EPC reviews new proposals for environmental rules/regulations and procedures from the engineering standpoint and potential implications for the Department.

  • Improving and simplifying processes – EPC works with OEP and regulatory staff on environmental requirements and processes for areas for improvement. EPC works jointly with OEP to develop guidance, templates, sample plans/details, and other tools for engineering staff to ensure project quality, consistency and permit-ability.
