Stormwater BMP Pollutant Removal Tools and Information

• Best Management Practice Accounting and Tracking Tool (BMP-BATT)
  BATT is a spreadsheet-based tool that provides accounting, tracking, and reporting for pollutant (nutrients and sediment) load reduction. The purpose of this tool is to provide permittees, developers and watershed managers means to account for and track over time the pollutant load reductions (total suspended solids (TSS), total phosphorus (TP) and total nitrogen (TN)) associated with implementing stormwater and NPS controls, and to track net increases or decreases in nutrient loading associated with changes in land uses within the area of interest (an MS4 area, specific watershed, etc.).
