About NPS Data

Under Clean Water Act Section 319(h), EPA awards grants for implementation of state NPS management programs. State grant recipients are required to report their progress Annually in meeting milestones, including reductions of NPS pollutant loadings and on improvements to water quality achieved by implementing NPS pollution control practices.

The Grants Reporting and Tracking System (GRTS) is the primary tool for management and oversight of the EPA’s Nonpoint Source (NPS) Pollution Control Program. GRTS pulls grant information from EPA’s centralized grants and financial databases and allows grant recipients to enter detailed information on the individual projects or activities funded under each grant. The data displayed in these pages is used by the Agency to respond to inquiries received from Congressional committees, the White House, and various constituent groups.
