National Pollutant Discharge Elimination System (NPDES) permitting requires municipalities and private businesses to adhere to increasingly stringent stormwater quality standards. Stormwater treatment technology can assist users in meeting those standards. Technology vendors, users, and permittees need credible information concerning Stormwater Control Measures (SCM) performance to comply with permit conditions in a timely and cost effective manner. The Stormwater Technology Testing Center (STTC) concept was developed to meet this need through the cooperative efforts of ODOT, Clean Water Services (a local municipal waste-water system), and numerous public and private stakeholders throughout Oregon, Washington, and other regions of the United States. The STTC will verify the maintainability performance characteristics and costs of innovative commercial-ready stormwater treatment technologies that have the potential to improve protection of water quality and the environment. STTC will provide designers, owners, and permittees of stormwater treatment technologies with an independent and credible assessment of the technology they are purchasing or permitting. The STTC will also have the capability to test three technologies simultaneously for compliance with the Washington Department of Ecology’s Technology Assessment Protocol – Ecology (TAPE) guidelines. Given that the STTC can be easily modified to accommodate other testing protocols, this facility presents multiple opportunities for interagency coordination nationwide, similar to coordination between the Washington State TAPE program and Oregon DOT (STEPP Workgroup, 2014). To date ODOT has invested over $1M, including FHWA STIC Incentive Program support. Significant progress has already been achieved by ODOT on this project including: • Business Plan Development • Maintainability Evaluation Protocol • Quality Assurance Project Plan Development (Approved by Washington Department of Ecology) • Site Design and Construction (grading, gravity flow and pumping conveyance systems, control systems, samplers, remote weather stations, etc.) Link to Informational Video: https://www.youtube.com/watch?v=ZKbGWiOrYBo&feature=youtu.be Overall objectives of the STTC include: • Identifying meaningful maintainability metrics for stormwater treatment technologies • Providing an objective testing and evaluation protocol and process for evaluating the maintainability performance of the technologies that have the most promising potential to reach specific stormwater quality objectives and meet stormwater quality requirements • Providing technology applicants with credible third-party verification of maintainability performance to facilitate successful technology commercialization and to enhance competitiveness in existing and new markets • Disseminating widely information comparing testing results and metrics to give technology designers, owners, and permittees confidence in the maintainability characteristics of the technologies they are investing in • Coordinating efforts with the Washington TAPE program in order to create a comprehensive stormwater treatment technology performance information source. • Providing streamlined and cost-effective evaluations by eliminating duplication of testing and auditing by public agencies, and duplication of effort by the manufacturers that provide products for evaluation.

The specific aim of this proposal is to provide funding for STTC calibration through completion, refinement, and testing of run protocols and business procedures. Proper calibration is essential to assure fair, repeatable, and defensible results when measuring maintainability. In support of FHWA research initiatives (for SP&R funds), the STTC and associated calibrated protocols and procedures will be ideal for downstream Technology Transfer opportunities nationwide. Further, once the facility is fully operational with calibrated run protocols and procedures, stormwater treatment research will be possible, and the run protocols and procedures can be applied to new testing facilities.

Work is currently underway to complete the calibration of the STTC. Additional partnerships are needed and are actively being pursued (please contact Kira Glover-Cutter; kira.m.glover-cutter@odot.state.or.us; (503) 986-2851). States are encouraged to commit to only the first and second year to accelerate STTC calibration completion. If full funding is received by June 2017, the STTC could be in full operation by Spring 2018. It is desired to complete all of the tasks described above in the 1st year if full funding becomes available. Based upon the current funding participation the schedule for completion of tasks is as follows: 1st Year: Tasks 1.7 [10%] 2nd Year: Tasks 1.2 and 1.8. [10%] 3rd Year: Tasks 1.3, 1.5, and 1.9 [10%] 4th Year: 1.1, 1.4, and 2.5 [10%] Currently insufficient funds: Task 1.6, 2.1-2.4, 2.6, 2.7, and 3.1-3.5 [60%] 100% SP&R Waiver has been approved.
