  3. Environmental Impacts • Construction Stormwater Impacts: • Stormwater runoff quality during construction • Stormwater runoff quality after construction • Primary Commitments: • Comply with Ohio EPA Construction NPDES Permits • Temporary sediment and erosion controls during construction • Post-construction stormwater management controls after construction (permanent) • Secondary Commitments: • Local stormwater programs or commitments Categorical Exclusion Training Class

  4. Addressing Impacts ODOT Responses: • Temporary sediment and erosion control during construction • Supplemental Specification 832 • Post-construction stormwater management controls (afterconstruction - permanent) • L&D Manual, Vol. 2 Drainage Design Categorical Exclusion Training Class

  5. Addressing Impacts Post-Construction Stormwater Management • ODOT BMP Toolbox • Vegetated Biofilter • Exfiltration Trench • Manufactured Systems • Extended Detention • Retention Basin • Infiltration Techniques • Bioretention Cell • Constructed Wetlands • All post-construction BMPs require long term maintenance plan Categorical Exclusion Training Class

  6. Environmental Impacts Online CE: • Only 1 question we need to answer… Categorical Exclusion Training Class

  8.

Routine Maintenance Projects What is Routine Maintenance? • ODOT L&D Manual, Vol. 2 Section 1112.2 • Berm repair or topsoil placement along shoulder • Bridge abutment repair • Bridge deck overlay • Bridge deck replacement • Chip sealing • Culvert repair/lining/some replacement • Curb repairs • Ditch cleanout • Fence repair/replacement • Full depth pavement repairs • Guardrail installation/replacement • Lighting maintenance • Linear grading • Loop detector repairs • Noise wall repair • Partial depth pavement repairs • Pothole filling • Resurfacing • Sign repair/maintenance • Signal installation/maintenance • Tree and brush removal • If not listed, the project is considered “new construction” Categorical Exclusion Training Class

  10. Routine Maintenance Projects What is Routine Maintenance? • ODOT L&D Manual, Vol. 2 Section 1112.2 • Berm repair or topsoil placement along shoulder • Bridge abutment repair • Bridge deck overlay • Bridge deck replacement • Chip sealing • Culvert repair/lining/some replacement • Curb repairs • Ditch cleanout • Fence repair/replacement • Full depth pavement repairs • Guardrail installation/replacement • Lighting maintenance • Linear grading • Loop detector repairs • Noise wall repair • Partial depth pavement repairs • Pothole filling • Resurfacing • Sign repair/maintenance • Signal installation/maintenance • Tree and brush removal • Routine Maintenance does not equal “Maintenance Project” Categorical Exclusion Training Class

  11. Environmental Impacts Question 1b: • Is the project in a Watershed Specific CGP Area? Categorical Exclusion Training Class

  12. Environmental Impacts Question 1c: • Not really a question, but remarks should clarify your assumptions… Categorical Exclusion Training Class

  13. Environmental Commitments Question 1d: • What are the commitments? Categorical Exclusion Training Class

  14. Environmental Commitments • Example Commitments: • Commitment 1: Project will need Notice of Intent submitted to EPA • Commitment 2: Project will need to comply with CGP or watershed specific CGP • Commitment 3: Project will address local stormwater issues • Commitments should be kept general at this point • Only commit to what we know for sure Categorical Exclusion Training Class
