Environmental Protection Agency (EPA) recognizes nonpoint source (NPS) pollution as “the leading remaining cause of water quality problems”. Pollutants commonly associated with NPS include nutrients (phosphorus and nitrogen), pathogens, sediment, and metals. Pollutant loads from nonpoint sources continue to impact drinking water supplies, recreation, fisheries and wildlife. The NPS Program provides financial and technical assistance to communities for locally led projects to meet the goal of the NPS Program:
- Restore and protect Colorado waters from the impacts of NPS pollution.
The pages below contain supporting information to help NPS partners plan for and manage NPS projects in partnership with the NPS Program.

Includes the NPS Management Plan and Annual Reports, EPA’s NPS Program and Grant Guidelines, and federal regulations.
Program documents
2022 Nonpoint source management plan.
- Project development resources, (e.g. eRAMS, watershed plan map, etc.), map of previous NPS projects, and project monitoring and evaluation resources to help determine pollutant sources and load reductions.
- Information on the contracting process, project administration and reporting (e.g. sampling protocols, Sampling Analysis Plan template, etc.)
Colorado’s NPS Program works with partners to implement voluntary NPS provisions of Reg. 85. The Division’s Nutrient Management Plan and 10-Year Water Quality Roadmap identifies voluntary actions for NPS provisions of Regulation 85:
- Collaborate with the agricultural community to implement BMPs;
- Work with partners to implement public information and education programs focused on NPS pollution prevention and restoration activities;
- Collaborate on the development and implementation of NPS monitoring programs; and
- Evaluating nonpoint source to point source nutrient trading proposals.
More information on Regulation 85 is available on the division’s clean water nutrients page, and on CSU’s outreach page on Reg. 85.
The NPS Program submits a Success Story to EPA annually to highlight where NPS best management practices in an impaired waterbody led to that waterbody meeting water quality standards. These restoration and protection projects are collaborative efforts, and reflect the continued effort across many entities to improve water quality in the state.
Explore these projects on EPA’s Success Story page.
The Water Quality Control Division’s Water Quality Engagement Webpage provides updates on regulations, guidance, and policies as well as engagement opportunities for the public.
