Nonpoint Source Program

Protecting human health and aquatic life in Oregon's rivers, lakes, and coastline

Nonpoint sources are often linked with agricultural, forestry, urban, and rural residential land use activities where rain or snow runs off to surface waters. As the runoff moves, it picks up and carries away natural pollutants and pollutants resulting from human activity, finally depositing them into lakes, rivers, wetlands, coastal waters, and groundwater.

Polluted runoff causes damage to fish, wildlife, and their habitat; damages drinking water supplies; promotes excessive weed growth; and degrades Oregon's scenic beauty and recreational opportunities. Nonpoint sources continue to be a leading cause of significant water quality impacts across the state and the nation as a whole.

The goal of DEQ's Nonpoint Source Program is to prevent and eliminate water pollution from nonpoint sources in all waterbodies in the state. A nonpoint source of pollution is any pollution entering a waterbody that does not come directly from a pipe. Through control of pollutant sources for all waterbodies, DEQ's goal is to meet water quality standards that protect human health and aquatic life. Oregon's NPS Program is an important part of the state's water pollution control programs because for some pollutants, nonpoint sources of pollution are the major sources of pollution to a waterbody.

Program Management Plan Update

DEQ invites the public to provide written comment on Oregon's updated Nonpoint Source Management Program Plan. The updated plan describes Oregon's programs and process for preventing and controlling nonpoint source pollution. The proposed plan is an update to the current plan approved in 2015. Subject to public review and comment, DEQ intends to submit the plan to the U.S. Environmental Protection Agency.

The public comment period has been closed on Monday, March 14, 2022 at 5 p.m.

EPA uses the plan and annual reporting on its implementation to make a determination if Oregon is making “satisfactory progress" with its nonpoint source program. This determination is what allows EPA to provide federal Clean Water Act 319 funds to the State. The current plan was developed in 2014/2015.

​​​The Oregon Nonpoint Source Pollution Program Annual Report documents the activities and accomplishments of the Oregon Department of Environmental Quality’s implementation of the state’s Nonpoint Source Program. DEQ develops the report annually to meet the requirements of Section 319 of the federal Clean Water Act and the U.S. Environmental Protection Agency’s 2014 Nonpoint Source Program and Grant Guidelines.

The report provides a summary of the nonpoint source activities implemented by the state during the past year and highlights the progress Oregon is making toward meeting the substantial challenges presented by nonpoint source pollution.​

The report includes progress updates on milestones, implementation targets and annual reporting requirements identified in the 2014 Oregon Nonpoint Source Management Plan and 2016-2018 Performance Partnership Agreement with EPA. ​
