TMDL Environmental Permitting Coordination

The MDOT State Highway Administration (MDOT SHA) is committed to meeting the requirements of the Chesapeake Bay TMDL through compliance with Maryland’s Watershed Implementation Plan for the Chesapeake Bay Total Maximum Daily Load (WIP). Coverage under the Regulated Urban Stormwater sector includes both Phase I and Phase II National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) stormwater discharge permit coverage for the MDOT SHA roadway network and maintenance facilities that have associated industrial stormwater discharge.  MDOT SHA maintains MS4 permit coverage for the SHA roadway storm drain systems in the 11 Maryland counties holding MS4 permits.  

Coastal Resources, Inc. (CRI) provided an Environmental Permitting Coordinator team to manage more than 11 tree planting projects, 7 stormwater management retrofits, 5 new stormwater BMPs, 14 grass swales, and 33 stream restoration projects throughout the 11 counties.  CRI was hand-picked for this role due to their in-depth knowledge of natural resource permitting and MDOT SHA process, and excellent working relationship with regulatory agencies. Specific services also included:  

  • Review of TMDL related water quality designs for permitability and potential natural resource issues.
  • Coordination and review of wetland and forest stand delineations.  
  • Coordination with the MDOT SHA TMDL Project Management Team, Environmental Programs Division and environmental agencies (MDE, COE, DNR, CAC, USFWS, M-NCPPC, and others) on pre-application meetings, jurisdictional determinations, and other issues as needed to address avoidance and minimization of natural resources and expedition of permit approval.
  • Coordination with the MDOT SHA TMDL Project Management Team to track permitting timeframes and schedules and minimize critical path issues related to permitting.
  • General management and coordination for TMDL projects related to NEPA/MEPA and permitting process including: archaeology, Section 106, RTE Species, SPAs, Tier II Waters, fish passage, Programmatic Categorical Exclusions, Critical Area Commission; wetland, waterway and floodplain permitting with MDE and USACE; roadside tree and Forest Conservation permitting, and other issues as needed to expedite the delivery of TMDL projects.
