The U.S. Environmental Protection Agency (USEPA) has identified three areas of metrics regarding the Response,
Assessment, and Evaluation Services (RAES) contract to report on a quarterly basis. These metrics relate to:
1. Employment
2. Subcontracting
3. Training
The metrics presented in this report are for the third quarter of Calendar Year 2022 (2022-Qtr3), cumulative totals for
the Calendar Year 2022 (2022 Total), and cumulative totals through this Period of Performance (POP Total). POP
Totals constitute all metrics from contract award to present. The employment data in this report represent Tetra Tech
staff and our Team subcontractors. Subcontracting data in this report represent our Team subcontractors and all
vendors, including laboratories. Laboratory subcontracting is not included when Tetra Tech evaluates the percent of
subcontracting metrics in our performance against goals in our RAES Navajo Employment and Training Plan.
Federal law allows for the voluntary collection of information regarding American Indian or Alaska Native (not
Hispanic or Latino) ethnicity but does not allow firms to inquire further. Therefore, Tetra Tech has provided this report
in compliance with current Equal Opportunity Employment Commission (EEOC) requirements regarding voluntarily
self-identification of race/ethnicity and gender. Within this report this classification category will henceforth be
referenced as "American Indian or Alaska Native".
Since award of the RAES contract, Tetra Tech has worked closely with Navajo entities to create employment and
training opportunities. To this end, Tetra Tech and Navajo Technical University (NTU) entered into a Memorandum of
Understanding (MOU) in May 2018. Working with NTU since that time, we have supported their efforts to grow
engineering and environmental sciences programs. With the support of Tetra Tech through our MOU, NTU won a 5-
year, a Tribal Colleges and Universities Program (TCUP) Grant with the National Science Foundation. Supporting
the implementation of the grant, Tetra Tech continues to be an active member of NTU's Engineering Advisory Board,
meeting with faculty to help with the development of additional courses, identify ways to attract students and to
expand training and certifications.
Consistent with RAES contract Appendix C, Section 9 Employment and Training Report, the following metrics are
provided in the sections below:
2.0 American Indian or Alaska Native Employment

Tetra Tech is committed to providing meaningful employment opportunities through a three-phased strategy: (1)
directly hiring American Indian or Alaska Native individuals under Tetra Tech and our Navajo-owned team
subcontractors; (2) procuring vendor services from companies that have received designation as Navajo-owned
companies to support work elements under the contract; and (3) providing direct employment through focused
outreach. Our goal is to provide direct economic benefits to Navajo-owned firms and American Indian or Alaska
Native individuals by committing 10 percent of awarded contract work in services and staffing.

SUBCONTRACTING
For the purpose of reporting subcontracting, Tetra Tech considers Navajo Priority 1 and Navajo Priority 2 firms
designated by the Navajo Nation Division of Economic Development Business Regulatory Department to be "Navajo
Owned Firms," During this period, Tetra Tech subcontracted additional Navajo Priority 1 services which will exceed
$660,000. While this was a significant amount of activity, that is not reflected in the current report as final invoices
have not been received. While we have included laboratory subcontracting dollars in the metrics of this report,
laboratory subcontracting is not included in Tetra Tech's subcontracting goals under RAES because EPA agreed
that no qualified Navajo Priority 1 or 2 laboratories currently exist. Based on the approved contract plans, Tetra Tech
has exceeded the requirements by 94%, The total dollars spent on subcontractors and Navajo Priority 1 and 2
subcontractors is provided in the graphics below. For the purpose of this report, Tetra Tech considers vendor
services and supplies under this "Subcontracting" metric,
