1 Stormwater Management Initiative Update

2 ODOT’s Goal Develop a streamlined stormwater runoff treatment program to: Develop a streamlined stormwater runoff treatment program to:  Meet all regulatory needs;  Provide ODOT with certainty regarding scope, schedule, and budget  Result in an overall environmental benefit and promote species recovery.

3 Components of the Stormwater Initiative Work Plan I. Streamline the DEQ Stormwater Management Plan Approval Process II. Develop Strategy/Process for ODOT Projects with T&E Species and Stormwater Effects III. Develop a Watershed Approach to Mitigate for Unavoidable Stormwater Effects

4 I. Streamline the DEQ Stormwater Management Plan Approval Process Problem Statement All applications for SWMPs reviewed in detail by DEQ, which results in  Multiple requests for more information, design changes  Constant danger of schedule slipping  Heavy load on DEQ/ODOT liaison

5 I. Streamline the DEQ Stormwater Management Plan Approval Process Determine Objectives/ Goal(s) Water Resources Impact Assessment Water Quality Management Design Internal ODOT Quality Control - QC Checklist Optimize Treatment Option Selection ODOT Submits to DEQ - Submittal Application Form - Project Description - Objectives and Goals - Stormwater Treatment Measures - Project Plan Sheets DEQ Reviews SWMP Submittal Package DEQ Approves SWMP

6 Where We are Now: DEQ  Interagency Agreement with DEQ and ODOT signed  DEQ and ODOT developing training for Region and DEQ staff  Training to be held in late spring/early summer 2007

7 II. Develop Strategy/Process for ODOT Projects with Stormwater Effects Problem Statement Stormwater had become a major impediment to efficient ESA process due to:  Lack of congruence in water quality requirements between DEQ and NMFS  Changing thresholds for effects determinations in ESA Section 7 consultations  Lack of early coordination to identify emerging issues (i.e., new pollutants of concern)

8 II. Develop Strategy/Process for ODOT Projects with Stormwater Effects Proposed Strategy/Process  Compile and synthesize literature on BMPs for stormwater treatment  Define water quality design storm  Develop water quantity guidance

9 II. Develop Strategy/Process for ODOT Projects with Stormwater Effects Proposed Strategy/Process (cont.)  Develop a BMP Selection Matrix and User’s Guide  Formalize a process to –Incorporate minimization of stormwater impacts into project design (Low Impact Development techniques) –Select most appropriate treatment BMPs for each project

10 II. Develop Strategy/Process for ODOT Projects with Stormwater Effects Proposed Strategy/Process con’t  Develop ESA Effects Determination Guidance  Develop template language for NLAA and LAA Determinations for Biological Assessments  Link the determinations of effect with the BMP Selection Matrix  Develop a performance measurement and reporting method

11 II. Develop Strategy/Process for ODOT Projects with Stormwater Effects Anticipated Benefits Regulatory Agencies  Meet regulatory requirements  Well-defined terms and conditions that allow for flexibility in application  Protect ESA-listed fish  Protect Oregon’s water quality and wetland resources

12 II. Develop Strategy/Process for ODOT Projects with Stormwater Effects Anticipated Benefits ODOT  Certainty in project development and construction  Reduction in project delays  Support ODOT’s Sustainability goals

13 II. Develop Strategy/Process for ODOT Projects with Stormwater Effects Where are we now?  BMP Summary Reports Completed  BMP Selection Matrix draft under review  BMP Selection Matrix Users’ Guide under review

14 II. Develop Strategy/Process for ODOT Projects with Stormwater Effects Where are we now (cont.)  Draft Water Quality Design Storm under review  Water Quantity Guidance under development  ESA Effects Determination Guidance for Water Quality under development

15 III. Develop a watershed approach to mitigate for unavoidable stormwater effects Problem Statement  Current approach to mitigate impacts of transportation projects on water resources is project specific, on-site treatment  Energy is devoted to mitigation efforts that can result in little net benefit to the watershed  Projects that can’t meet Resource Agency goals subject to squabbling and uncertain additional requirements

16 III. Develop Watershed Approach to Mitigate for Unavoidable Stormwater Effects Proposed Strategy/Solution (In Development)  Technical evaluation of needs and opportunities for mitigation  Political effort to achieve agreement on goals, methods, and interagency coordination

17 III. Develop Watershed Approach to Mitigate for Unavoidable Stormwater Effects  Work will commence when Task II is close to completion
