Would you like to know how to evaluate your stormwater BMP for installation and long-term operations and maintenance? This video will walk you through the ITRC Stormwater BMP Evaluation Team Screening Tool results and how to compare your site to criteria established by reliable sources across the US.

The screening considerations section provides principles, information and a BMP Screening Tool to enable users with stormwater management responsibilities to make better decisions for optimal stormwater treatment. It is important when selecting a BMP that the land use, soil types and pollutant, pollutant loads, topography, climate, and available area are known or estimated. Based on this information, the BMP Screening Tool facilitates the consideration of the many stormwater BMPs with links to specific information, existing guidance and other resources. The BMP Screening Tool helps streamline the marriage of site pollutants and characteristics with applicable BMPs currently available. It provides details on what site data the user needs to help find applicable BMPs and then ultimately leads the user to potential BMPs that the can be considered for implementation at their facility.

The BMP installation section provides guidance for the installation of post-construction stormwater BMPs to ensure they perform as intended from a water quality perspective and are in line with current regulatory and industry standards. The guidance outlines information and recommendations intended to ensure the user has the necessary tools to develop a design plan and install a BMP that will perform effectively into the post-construction operation and management phase. This section offers information on contracting for installation of post-constructions BMPs including the installation process and timeline, general inspection and protection guidelines during site work, and considerations for site-specific conditions.

The purpose of the BMP operations section is to provide guidance on necessary BMP maintenance to ensure proper operation and thus, pollutant removal performance. BMPs employ a variety of pollutant removal methods and thus require different maintenance activities to ensure proper operation. This section provides information to guide the user on what maintenance practices may be required and at what frequency, for different BMPs, making sure to address issues related to the primary removal mechanism of the BMP. Additionally, the section describes what should be examined according to the primary removal mechanism of the BMP and how often inspections should occur. References to existing operations and maintenance guidance, for different states and regulatory agencies, are also provided.
