Coastal Nonpoint Pollution Control Program

Nonpoint source (NPS) pollution, unlike pollution from industry, comes from many diffuse sources. NPS pollution is caused by rainfall or snowmelt moving over and through the ground, picking up pollutants along the way. Nonpoint source pollution is the single largest source of water quality problems in the U.S. Sources may include:

  • Excess fertilizers, herbicides, and insecticides from agricultural lands and residential areas;
  • Oil, grease, and toxic chemicals from urban runoff and energy production;
  • Sediment from improperly managed construction sites, crop and forest lands, and eroding streambanks;
  • Salt from irrigation practices and acid drainage from abandoned mines;
  • Bacteria and nutrients from livestock, pet wastes, and faulty septic systems;
  • Atmospheric deposition and hydromodification are also sources of nonpoint source pollution.

The Coastal Nonpoint Program Coordinator works toward the achievement of EPA management measures that combat sources of nonpoint source pollution. The measures should be accomplished not only by the action of the Coordinator but also through the actions already taking place in local government and regional and nonprofit organizations. Therefore, programs and projects taken on by other organizations can help the Indiana Coastal Program meet its management measure objectives. For information on enabling legislation and program implementation, please see the nonpoint program factsheet.

Technical Assistance

One aspect of the nonpoint coordinator position is to provide technical assistance to government and regional and nonprofit organizations for the implementation and support of nonpoint management measures. We look forward to filling the gaps where technical assistance is lacking in areas such as statistics and ecological economics. Please check back regularly for helpful technical documents.

Coastal Nonpoint Grants Program (This program has not received funding since 2009)

The Coastal Nonpoint Program has established a pass-through grant program to assist local communities and watershed partners in protecting coastal water quality and aquatic habitats. The program addresses a number of nonpoint source pollution categories including agriculture, urban/rural areas, hydromodification, and marinas along with the protection of wetland and riparian areas. The Coastal Nonpoint Program uses the watershed approach in implementing its program. Therefore all projects must be located within the Little Calumet-Galien Watershed or clearly demonstrate a direct benefit to the program area.

Program Approval Status

Based on Indiana's 6217 Program document submittal in 2005, both NOAA and EPA found that the program meets many of the requirements of section 6217 and will approve the program with conditions. The Findings and Environmental Assessment documents below outline NOAA's and EPA's findings and conditions that Indiana must meet for full 6217 program approval.
