Clean Water Act Section §319 - Nonpoint Source Pollution Control Program Grants

Salt River Pima Maricopa Indian Community Streambank Restoration and Erosion Control Project
Salt River Pima Maricopa Indian Community streambank restoration and erosion control project funded through the Clean Water Act Section 319 program to reduce sedimentation by laying out rocks along the banks to hold down dirt.

Purpose: The purpose of the Nonpoint Source (NPS) Pollution Control Program is to assist tribes develop and implement polluted runoff control programs that address critical water quality concerns at a watershed level.

What is NPS? NPS pollution - polluted runoff - occurs when rainfall, snowmelt, or irrigation water runs over land or through the ground, picks up pollutants, and transports them into surface waters or ground water. Major nonpoint sources of pollution include agricultural practices; unrestricted livestock grazing; poor siting and design of roads, highways, and bridges; forestry; urban runoff; abandoned mines; construction sites; channelization of streams; and hydromodification, such as building and maintaining dams and levees.

Eligible Activities (but not limited to this list):

  • Road stabilization/ removal;
  • Riparian planting;
  • Stream channel reconstruction;
  • Low impact development projects/storm water management;
  • Livestock exclusion fencing;
  • Springs protection;
  • Septic system rehabilitation;
  • NPS ordinance development;
  • Project monitoring (pre-project, during project, post-project);
  • Development of a watershed-based plan;
  • Training which assists the applicant in development NPS implementation projects;
  • Staff time and materials towards implementing projects; and
  • NPS education and outreach relevant to successful implementation of NPS projects.
  • Base Funding: Funds are allocated based on tribe's land area. If a tribe has 640,000 acres or less of land, the allocation is $30,000.If a tribe has more than 640,000 acres, the allocation is $50,000.
  • Competitive Funding: After all base allocations are made to tribes, the remaining amount from overall national allocation is up for competition to all eligible Tribes, regardless of land size. Tribes applying for competitive funds can request up to $150,000 of federal funding.

Eligibility Requirements: Federally recognized Indian Tribes must be determined eligible to apply for CWA Section 319 funding before applying.

CWA Section §104(b)(3) - Wetlands Program Development Grants

Colorado River Indian Tribes - Wetlands at 12 Mile Lake
Wetlands at 12 Mile Lake on the Colorado River Indian Tribe's Reservation.

The goals of EPA's wetland program include increasing the quantity and quality of wetlands in the U.S. by conserving and restoring wetland acreage and improving wetland condition. In pursuing these goals, EPA seeks to build the capacity of all levels of government to develop and refine effective, comprehensive programs for wetland protection and management.

Purpose: The wetlands program development grant (WPDG) provides states, tribes, local governments, interstate agencies, and intertribal consortia an opportunity to carry out projects to develop and refine comprehensive wetland programs. WPDGs provides eligible applicants an opportunity to conduct projects that promote the coordination and acceleration of research, investigations, experiments, training, demonstrations, surveys, and studies relating to the causes, effects, extent, prevention, reduction, and elimination of water pollution.

Funding: EPA typically awards between $50,000 to $350,000 per project grant. Funding is dependent upon amount requested and the overall size and need of the project.

Additional Wetlands Information

Starting to think about developing a tribal wetlands program?
Experience with many tribes and states have distilled a set of core elements, actions, and activities that together comprise a comprehensivewetland program. EPA has summarized these common core elements, actions, and activities in the Core Elements of an Effective State and Tribal Wetlands Program Framework, also called the Core Elements Framework (CEF). The CEF describes in greater detail each of the four core elements that make up an effective state/tribal wetland program. The four core elements are:

  • Monitoring and assessment
  • Regulation
  • Voluntary restoration and protection
  • Wetland WQS

Each of these four core elements is comprised of several broad "actions" that if collectively carried out would complete that core element. In addition, each action is made up of several more specific "activities" which are the actual steps a state/tribal/local government would carry out to achieve each option. The four core elements, the setof development or refinement activities and the specific actions under the four core elements that are eligible for funding are listed at Wetland Program Development Grant.

Further Information

The full CEF can be found at Core Elements of an Effective State and Tribal Wetlands Program Framework. Some of the activities outlined in the full CEF are not eligible for the WPDG funding. The CEF provides a menu of activities for wetland program development, regardless of whether such activities are eligible for WPDG funding.

Eligibility Requirements: There are no eligibility requirements for Tribes except the tribe must be federally-recognized.

CWA Tribal Set-Aside Program - Wastewater Infrastructure

Wetland marsh

General Description:  EPA utilizes the Indian Health Service (IHS) Sanitation Deficiency System (SDS) list to select projects that are eligible for funding. Tribes have an option of receiving a direct grant or receive an Interagency Agreement (IAG) withtheir corresponding IHS area office. EPA contacts the selected tribe directly and requires a written response on the selected option to receive funds.

Examples of Eligible Activities
  • Interceptor sewers
  • Wastewater Treatment Facilities (conventional or alternate)
  • Infiltration/Inflow correction
  • Collector sewers
  • Major sewer rehabilitation
  • On-site systems (e.g., septics)
Stormwater Basin at Gila River Indian Community

Water Quality Standards

Water Quality Standards (WQS) are the foundation of the nation’s surface water quality protection program. See the National EPA Water Quality Standards Web site for complete information including basic descriptions and documents for approved tribal water quality standards.

Indian tribes can administer the WQS program on Tribal Land. With an approved WQS program, an Indian tribe can set the water quality goals for all surface waters (e.g., streams, rivers, lakes, andwetlands) on the reservation. The tribe will also determine whether activities which require a federal license or permit are consistent with the tribe’s WQS.

How authorization under the Clean Water Act benefits Indian tribes
  • Under Section 401 of the Clean Water Act, if a requested license or permit within the reservation results in discharge adversely affecting water quality, an eligible Tribe may certify whether the requested license or permit satisfies the Tribe’s WQS.
  • Tribes establish water quality goals for reservation waters to protect water resources.
  • Tribes designate uses of waterbodies which may include cultural or traditional purposes.

Questions About Program Authorization

1. What does a Tribe need to start the WQS process for our reservation lands?

Before a tribe may adopt standards consistent with the Clean Water Act, it must receive authorization to administer the WQS program.

2. What is program authorization?

EPA uses four criteria to determine the eligibility of a tribe to administer the WQS program. These are:

  • The tribe must be federally recognized
  • The tribe must have a governing body that carries out substantial governmental duties and powers
  • The tribe must have authority to administer the program for reservation waters
  • The tribe must be capable of administering an effective WQS program

Upon receiving authorization, the tribe can submit its WQS for approval to EPA. You can submit both applications for program authorization and Tribally adopted WQS at the same time.

3. How does a tribe apply for the WQS program?

There is no standard application for program authorization. Tribes must submit documentation showing that it meets the four criteria described above. Documentation should include copies of triballaws or regulations and other supporting information. The appropriate EPA Regional Administrator reviews the information.

Region 9 has approved eleven Tribal WQS programs
  • White Mountain Apache
  • Hoopa Valley Tribe
  • Hualapai Tribe
  • Big Pine Band of Shoshone Paiute Indians
  • Bishop Paiute
  • Dry Creek Rancheria Band of Pomo Indians
  • Havasupai Tribe
  • Navajo Nation
  • Twenty-Nine Palms Band of Mission Indians
  • Pyramid Lake Paiute Tribe
