Background

The purpose of the Clean Water Act Indian Set-Aside (CWISA) Program
is to provide funding for wastewater infrastructure to federally recognized
tribal governments and Alaska Native Villages. Funds may be used for
planning, design, and construction of wastewater collection and treatment
systems. The CWISA Program is administered by the Environmental
Protection Agency (EPA) in cooperation with the Indian Health Service
(IHS). The CWISA Program was established by the 1987 Amendments to
the Clean Water Act, in Section 518(c).

How to Apply

To apply for funding from the CWISA Program, tribes must first contact their IHS Area Office (www.dsfc.ihs.
gov/staff) to determine if their wastewater needs are eligible to be entered into the HIS Sanitation Deficiency
System (SDS) list. EPA provides funding for wastewater projects that are ranked and listed on the SDS list.

How the Program Works

The SDS identifies current sanitation deficiencies for existing tribal homes; projects for future needs will not be
considered. EPA uses the SDS list to identify priority wastewater projects for funding. CWISA Program Coor-
dinators in each EPA Region and IHS Area work together to determine the projects to be funded based on the
ranking of projects in the SDS and available CWISA Program funding. Projects are ranked in the SDS based on
eight factors: health impact, existing deficiency level, previous service, capital cost, operation and maintenance
(O&M) capability, contributions, local tribal priority, and local conditions. For example, projects that would
resolve public health concerns would rank higher than projects designed to rectify water quality problems.

Tentative Schedule

DATE MILESTONE

June - July IHS Area Offices review and rank projects submitted to the Sanitary
Deficiency System (SDS)

August - October IHS Headquarters reviews IHS Area Offices SDS project submissions

November Final SDS lists are made available to EPA Regional CWISA Program
Coordinators

April - September EPA Regional CWISA Program Coordinators notify tribes that have been
selected for funding and award CWISA Program funds


-------
Annual Funding Levels

EPA Region 9 receives over $10 million and funds approximately 40 wastewater projects.

•	The average award amount for individual projects is $300,000. In recent years, award amounts have ranged
from $50,000 to over $3,000,000. Award amounts will vary depending on the type of project.

•	No matching funds are required.

Eligible Projects

All projects funded by the CWISA Program must support wastewater-related activities or projects. The CWISA
Program funds cannot be used to pay for the cost of O&M of the wastewater facility nor can they be used to pay
for repairs to the treatment system in emergency situations. Project components that are eligible for funding
include (but are not limited to):

•	Project planning, design, and preparation of Preliminary Engineering
Report (PER)

•	Infrastructure construction and major sewer rehabilitation

•	Wastewater treatment facilities (conventional or alternative)

•	Correction of combined sewer overflows

•	Collector sewer pipelines

•	On-site wastewater treatment systems (e.g., septic systems)

•	Project follow-up and drafting as-built drawings of funded wastewater
projects

•	Operator training of new infrastructure equipment for first year of
project

Project: Gilson Wash Lift Station

Project construction was completed in January of 2016 to serve 823
homes with community wastewater service for the San Carlos Apache
Tribe. The scope at the Gilson Wash Lift Station included: replacement
of the exi sting pumps, pump controls, piping, electrical service, and all
electrical components; adding concrete risers to the existing lift station
wet well and valve vault, replacing the lift station and valve vault covers,
installation of a new metering manhole, installation of a light pole, con-
structing a raised earthen lift station site pad, bypass pumping, and in-
stallation of perimeter fencing. Prior to the lift station rehabilitation, the
facility had only one operable pump that was 13 years old. The lift station was at capacity and had deteriorated to
the point that it was not correctable by routine maintenance. There was imminent threat that the facility would
fail within two years. The combined cost of this project work was $925,000, including $659,000 of EPA funds.
