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 ODEQ 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 ODEQ Stormwater Management Plan Approval Process Problem Statement All applications for SWMPs reviewed in detail by ODEQ, which results in Multiple requests for more information, design changes Constant danger of schedule slipping Heavy load on ODEQ/ODOT liaison
5
I. Streamline the ODEQ Stormwater Management Plan Approval Process Proposed Strategy/Solution ODOT to develop a more rigorous QC Process (i.e., ODOT review equivalent to existing DEQ review) Shift QC for SWMPs from ODEQ to ODOT ODEQ moves into more of a QA role
6
I. Streamline the ODEQ Stormwater Management Plan Approval Process Develop PS Water Resources Impact Assessment Water Quality Management Design Internal ODOT Quality Control - QC Checklist Optimize Treatment Option Selection ODOT Submits to DEQ - QC Checklist - Project Description - Goals - Mitigation Measures - Project Plan Sheets DEQ Reviews Submittal DEQ Approves SWMP
7
I. Streamline the ODEQ Stormwater Management Plan Approval Process Anticipated Benefits ODEQ Assurance that state water quality standards are being met through ODOT diligence Substantial reduction in amount of time reviewing SWMPs More time to provide early project support More time to participate in programmatic and policy issues
8
I. Streamline the ODEQ Stormwater Management Plan Approval Process Anticipated Benefits ODOT Shorter timeframe for approval of SWMPs Higher degree of certainty about requirements and schedule, based upon well-defined expectations
9
I. Streamline the ODEQ Stormwater Management Plan Approval Process Where are we now:
10
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 ODEQ and NMFS Changing thresholds for effects determinations in ESA Section 7 consultations Difficulties in using NMFS HCD Guidance
11
II. Develop Strategy/Process for ODOT Projects with Stormwater Effects Proposed Strategy/Process Compile and synthesize literature on BMPs for stormwater treatment Define an appropriate water quality design storm for ODOT projects Develop a BMP Selection Matrix Formalize a process to select BMPs Develop guidance for water quantity issues Develop a performance measurement and reporting method
12
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
13
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
14
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 don’t meet Resource Agency goals subject to squabbling and uncertain additional requirements
15
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
16
III. Develop Watershed Approach to Mitigate for Unavoidable Stormwater Effects Work will commence when Task II is close to completion
17
III. Develop a watershed approach to mitigate for unavoidable stormwater effects Anticipated Benefits Increased flexibility for projects’ water quality mitigation Targeted and maximized use of resources to achieve the greatest environmental results Increased opportunities for improved environmental conditions because of the focus on watershed objectives
18
Where We are Now: DEQ Draft QC Checklist in final DEQ review Draft Stormwater Management Plan Checklist in final DEQ review MOA in final ODOT pre-DoJ review Water Quality Goals and Performance Standards in development
19
Where We are Now Stormwater Effects Active working group with NMFS, USFWS, EPA and DEQ Design Storm survey complete –Work beginning on defining criteria Literature review complete, focused review beginning
20
Where We are Now Stormwater Effects Agreement that adequacy of design selection process and BMP selection matrix will be memorialized in Biological Opinions Agreement that the selection process and BMP matrix can facilitate batched BOs Work order for Matrix development is in the works Work order includes formulating strategy for development of the Watershed Approach
