DEEP: Nonpoint Source Management

Nonpoint Source (NPS) Pollution Management

Many activities associated with various land uses within Connecticut have the potential to contribute pollution to ground and surface water resources.  Water pollution that is not concentrated within a drainage system, or discharged from a point, such as a pipe, is called nonpoint source pollution.  Potential sources of Nonpoint Source Pollution can include agriculture, waste from domestic animals and wildlife, malfunctioning septic systems, runoff from impervious surfaces and managed turfgrass, soil erosion, atmospheric deposition, marinas and boating activity, and others.  Pollutant levels, or loadings, from nonpoint sources can be increased by weather conditions which cause stormwater runoff or snowmelt.  If pollutant concentrations from these nonpoint sources are high enough, uses of those surface or groundwaters for public water supplies, recreation, or aquatic life may become impaired

In Connecticut, stormwater pollution from urban areas that is collected in stormdrains, or that discharges from construction, commercial, or industrial sites, is regulated by stormwater general permits, so is technically considered point source pollution.  More information on Stormwater Management and Permitting

The Connecticut Department of Energy and Environmental Protection has worked to develop programs, technologies and legislation with both local and national significance that are protective of water resources, and has led a national pilot program to monitor nonpoint source pollution at residential development sites.

A significant component of Connecticut DEEPís Nonpoint Source Management Program consists of implementing the EPA Clean Water Section 319 Program.

GRTS: Grant Reporting and Tracking System
 
State grant recipients are required to report their progress annually in GRTS, including reductions of NPS pollutant loadings and improvements to water quality achieved by pollution control practices.  GRTS enables EPA and States to demonstrate the accomplishments achieved with the use of 319 grant funds.  The data entered into GRTS is used by EPA to respond to inquires received from Congressional committees, the White House, and various constituent groups.
 
Grant recipients should fill out the spreadsheet XLS form, save it, and email it to your DEEP Watershed Manager.  Macros must be enabled.
EPA's GRTS Home has more information on GRTS
