WASHINGTON, DC, Oct. 21, 2009 -- EPA's Nonpoint Source Grants Reporting and Tracking System (GRTS) is the primary tool for management and oversight of state Nonpoint Source (NPS) Management Programs under Section 319 of the Clean Water Act. EPA recently added new tools to the GRTS database to enable the public to search for information about NPS pollution control projects.
One way to search the database is to perform a criteria-based query. This method is best for finding 319 projects that meet certain conditions; for example, NPS projects that implement a Total Maximum Daily Load to control mine waste, or projects implementing best management practices for waters polluted by urban runoff. To search for projects, visit http://iaspub.epa.gov/grts/projects
Another new search tool is the interactive map, which enables browsing for project information by watershed. Simply use the find, pan, and zoom buttons to navigate to the location of interest, and the 319 projects will appear, summarized by watershed. At a regional scale, projects are displayed by sub basins (8-digit hydrologic units), and at a local scale, by sub watersheds (12-digit hydrologic units). Check out the GRTS Map Viewer at: http://iaspub.epa.gov/grts/map
