NOTE: The Interstate Technology and Regulatory Council (ITRC) released a new guidance document called Stormwater Best Management Practices Performance Evaluation. This Stormwater BMP guidance offers the user details on post construction BMP lifecycle processes including contracting, cost considerations, installation factors including construction challenges, inspection checklists, and quality control and record drawings. It goes on to address long-term technology- and performance-based operational strategies, including aspects such as routine and non-routine maintenance. Data and information from existing publicly available BMP performance programs has been incorporated into an online BMP Screening Tool. Using site-specific pollutant treatment requirements and installation considerations, the Tool can assist the user by identifying a list of BMPs that may be appropriate for a given site. The Tool also provides users summarized information on the treatment efficiency, installation requirements and maintenance issues regarding the identified BMPs, with links to access more detailed information.
