    Table of Performance by BMP Category and Common Pollutant Type (2011) This 1-page tabular summary provides the median influent and effluent event mean concentrations, 95th percentile values and number of studies by commonly reported constituent and BMP category. Updated November 2011.
    Table of BMPs by State (2011) This 1-page table provides the numbers of various BMP types included in the database by state; Updated November 2011.
    Summary of Cost Data (2007) This spreadsheet summarizes the cost data currently included in the database. Provision of cost data is optional for data providers and is an on-going data need.
    Summary of Non-structural BMP Data (2008) This Excel file summarizes non-structural BMP datacurrently included in the database. Additional non-structural performance data are needed. Existing data are primarily derived from the National Urban Runoff Program (NURP).
    List of Data Providers (2007)
    Studies Removed from the BMP Database in 2009
    This table provides a list of data providers and the number of studies that they have provided to the database. A statement regarding studies removed from the database in 2009 is also provided.
