At a Glance

The EPA's Enhanced Personnel Security Program Is on Track,
but Challenges to Full Implementation Remain

Why We Did This Evaluation

To accomplish this objective:

The U.S. Environmental Protection
Agency Office of Inspector General
conducted this evaluation to determine
the EPA Personnel Security Branch's
progress in implementing a fair and
effective enhanced personnel security
program in accordance with the
director of National Intelligence's
performance standards.

Executive Order 13467 requires all
executive branch agencies to
implement reforms to enhance their
personnel security programs. These
reforms are intended to establish a
single vetting system for the federal
government. For this evaluation, we
assessed "fairness" and "effectiveness"
as the extent to which the EPA is on
track to achieve full implementation of
the enhanced personnel security
program by established milestones and
is compliant with the applicable policies
and guidance.

To support these EPA mission-
related efforts:

•	Compliance with the law.

•	Operating efficiently and
effectively.

To address this top EPA
management challenge:

•	Managing grants, contracts, and
data systems.

What We Found

As of October 2023, the EPA's Personnel Security Branch, or PSB, has successfully met all
milestones and requirements to date to fairly and effectively implement the director of
National Intelligence's enhanced personnel security program, known as the Trusted
Workforce, orTW, Program. Specifically, the PSB has completed the first two of the
program's three implementation steps, referred to as TW 1.25, TW 1.5, and TW 2.0. The
final step, TW2.0, must be completed by March 30, 2026, and will culminate in full
implementation of the program. As of October 2023, the PSB is on track to meet full TW 2.0
implementation. To prepare for full implementation, the PSB has already adopted all
applicable Office of the Director of National Intelligence policies, procedures, and controls.

The TW Program is designed to provide a continuous vetting environment that allows the
PSB to track any risks to personnel security in real time. The PSB's most significant
remaining challenge is ensuring that there is sufficient capacity to meet the full TW 2.0
continuous vetting requirements by the March 30, 2026 milestone. As of October 2023, the
PSB had eight staff to implement the TW 1.5 requirements to provide continuous vetting
services for the approximately 1,100 EPA employees classified as the Agency's national
security population. Full TW2.0 implementation will require continuous vetting services for
the entire population of EPA employees and applicable contractor personnel—nearly
22,000 individuals, or 20 times the number vetted for TW 1.5. In addition, the PSB must
also significantly increase the level of continuous vetting services it provides from TW 1.5 to
TW 2.0 in 18 months. This rapid increase in workload, both in population served and
services provided, will require sufficient implementation capacity, including more PSB staff
who are appropriately trained to conduct continuous vetting tasks in a timely manner. If the
PSB plans now for its additional resource needs, it will prevent delays in full TW 2.0
implementation, reduce national security risks, and ensure a fair and effective personnel
security program.

If the EPA does not adequately plan to increase the PSB's
capacity to respond to a 20-fold increase in employees
receiving continuous vetting services, delays in processing
and managing full TW 2.0 implementation may increase the
risk to national security from insider threats.

Recommendation and Planned Agency Corrective Action

We recommend that the assistant administrator for Mission Support develop a plan for
how the PSB will achieve the capacity necessary to meet the requirements of full TW 2.0
implementation. The Agency agreed with our recommendation and provided an
acceptable planned corrective action and estimated milestone date. We consider the
recommendation resolved with the corrective action pending.

Purpose

The U.S. Environmental Protection Agency Office of Inspector General initiated this evaluation to
determine the EPA's progress in implementing a fair and effective enhanced personnel security program
in accordance with the director of National Intelligence's performance standards.

Top Management Challenge Addressed

This evaluation addresses the following top management challenge for the Agency, as
identified in OIG Report No. 24-N-0008. The EPA's Fiscal Year 2024 Top Management
Challenges, issued November 15, 2023:

• Managing grants, contracts, and data systems.

Background

Certain EPA positions require security clearances, which are granted on an individual and need-to-know
basis, to enable access to classified national security information and secure facilities. To receive a
security clearance, an employee undergoes a background investigation. Prior to recent background
investigation reform efforts, which began in 2008 and is detailed in the next paragraph, the federal
government required periodic reinvestigations every five to ten years to reassess an employee's
suitability or fitness to retain access to classified information. If any security risks or behaviors were
discovered during reinvestigation, they were adjudicated to determine the employee's continued
eligibility to remain in the position. However, because periodic reinvestigations were infrequent,
ongoing employee actions were not assessed in real time for behaviors that may have indicated the
existence of an insider threat. Additionally, the security clearance process is lengthy. In fiscal year 2022,
it generally took at least two-and-a-half months and as long as six-and-a-half months to complete the
process, depending on the type of clearance. Long processing times increase national security risks,
prevent personnel from beginning work, hinder the hiring of experienced and the best-qualified
personnel, and increase costs to the federal government.

Key Terminology

•	An insider threat is defined as the threat that an employee or a contractor will use
authorized access, wittingly or unwittingly, to do harm to the security of the United States.

•	Adjudication is an evaluation of the information contained in the national security
background investigations and other source documents. This evaluation determines an
individual's initial or continued national security eligibility.

To address these limitations, the federal government began overhauling personnel security clearance
processes in the early 2000s. Continuous evaluation and subsequent continuous vetting policies form
the cornerstone of these efforts. Authorized and defined by Executive Order 13467 in 2008, continuous
evaluation leverages automated record checks to assist in the ongoing assessment of an individual's
continued eligibility for access to classified information. Continuous evaluation supplements, but does
not replace, periodic reinvestigations. Added to Executive Order 13467 in 2017, continuous vetting

24-E-0020

-------
replaces periodic reinvestigations by providing a real-time review of a covered individual's background.
The Office of the Director of National Intelligence, or ODNI, describes continuous vetting as an
"evolution of the continuous evaluation concept."

There are three key mandates of the vetting reforms:

•	Executive Order 13467, Reforming Processes Related to Suitability for Government
Employment, Fitness for Contractor Employees, and Eligibility for Access to Classified National
Security Information, as amended: This executive order requires all executive branch agencies,
including the EPA, to implement reforms to enhance their personnel security programs. In
addition to authorizing the continuous evaluation of covered individuals, meaning employees or
contractors eligible to access classified information or hold a sensitive position, the executive
order designated the director of National Intelligence and the director of the Office of Personnel
Management as the Executive Agents responsible for developing policies and procedures for
personnel vetting reform. The executive order also established a Security, Suitability, and
Credentialing Performance Accountability Council, directed by the Executive Agents and which
we refer to hereafter as the Performance Accountability Council, to drive implementation of
personnel security reform, ensure accountability of agencies, and establish annual goals and
progress metrics.

•	Intelligence Authorization Act for Fiscal Year 2016 (Pub. L. 114-113, codified at 5 U.S.C. § 11001):

This Act required the director of National Intelligence to direct each agency to implement a
program to provide enhanced personnel security reviews of covered individuals. The program was
to include automated record checks for each covered individual not less than two times every
five years.

•	Security Executive Agent Directive 6: The ODNI established a series of directives to guide
personnel security reform. On January 12, 2018, the ODNI issued Security Executive Agency
Directive 6, which instructed all executive branch agencies to implement the continuous
evaluation of covered individuals and which outlined the agencies' responsibilities to achieve
the successful implementation of that directive.

Trusted Workforce 2.0 Initiative

To meet the continuous evaluation requirements of Executive Order 13467, as amended, and to revise
the federal personnel vetting process, the Performance Accountability Council launched the Trusted
Workforce 2.0, or TW 2.0, Program in 2018. TW 2.0 is being implemented in two phases. Phase one,
which has been completed, focused on reducing and removing the backlog of periodic reinvestigations.
Phase two, which is ongoing, focuses on establishing a new governmentwide approach to personnel
vetting. Phase two involves a multistep implementation process that progresses from TW 1.25 to TW 1.5
and finally to TW 2.0, with continuous vetting requirements gradually increasing through the steps. For
example, TW 1.5 requires automated record checks for just the national security population, while the
fully implemented TW 2.0 requires that the entire workforce be enrolled in the program for continuous
vetting. Agencies were required to meet the TW 1.25 milestones by September 30, 2021, and

24-E-0020

-------
TW 1.5 milestones by September 30, 2022.1 In June 2023, the Performance Accountability Council
extended the milestone for full TW 2.0 implementation, originally scheduled for the end of fiscal year
2024, to March 30, 2026.

The Performance Accountability Council has issued policies and guidance governing phase two of TW 2.0
Program implementation, including Transforming Federal Personnel Vetting: Continuous Vetting and
Other Measures to Expedite Reform and Transition to Trusted Workforce 2.0, published in January 2021,
and Trusted Workforce 2.0 Implementation Strategy Endorsement, originally published in April 2022 and
routinely updated. A key component of TW 2.0 includes incorporating automated record checks into the
continuous vetting processes. Automated record checks help ensure the continued eligibility of each
covered individual to access classified information and hold a sensitive position by continuously
identifying security risks related to seven categories:

•	Terrorism, such as cases that are flagged for additional research in the ODNI's Terrorist
Identities Datamart Environment system, the U.S. government's central database on known or
suspected international terrorists.

•	Foreign travel, including the U.S. Department of Homeland Security's advanced passenger
information system and border crossing information, which provide international-travel-related
information for personnel, such as airport codes and dates of travel.

•	Financial activity, such as an unusual infusion of assets of $10,000 or more; the failure to pay
taxes; and bankruptcy claims from courts and the Internal Revenue Service.

•	Criminal activity, such as daily criminal record checks and monthly checks of the U.S. Treasury's
Financial Crimes Enforcement Network.

•	Personal credit, including annual credit checks and credit history information.

•	Public records, including quarterly public record checks via commercial databases that provide
these types of services.

•	Employment eligibility, such as validation checks for eligibility for enrollment in continuous
evaluation through the Scattered Castles intelligence community personnel security database.2

These automated record checks are conducted by the U.S. Department of Defense through its Defense
Counterintelligence and Security Agency, or DCSA. The DCSA conducts nearly all security background
investigations provided for the federal workforce. The DCSA also provides personnel vetting services

1	TW 1.25 was not required for agencies that were able to meet the TW 1.5 minimum standards following the
publication of the Performance Accountability Council's Executive Agents' Transforming Federal Personnel Vetting:
Continuous Vetting and Other Measures to Expedite Reform and Transition to Trusted Workforce 2.0.

2	Scattered Castles is an intelligence community database that verifies personnel security access and visit
certifications. Intelligence Community Policy Guidance 704.5 Intelligence Community Personnel Security Database
Scattered Castles, dated October 2008, mandates the recognition, use, and reciprocity of Scattered Castles across
all components of the intelligence community.

through its information technology system, the National Background Investigative Services. Once fully
deployed, that system will include a range of tools and data repositories to support agencies through aii
stages of personnel vetting, including continuous vetting. In July 2023, the EPA's Personnel Security
Branch, commonly referred to as the PSB, informed us that the National Background Investigative
Services are not fully operational, and not ail systems and software applications are consistently
available to input new data or generate continuous vetting reports. However, if the record checks
identify any security risks, the DCSA assesses the alert validity and the need for further investigation.

Another key component of TW 2.0 is a streamlined set of investigative tier categories. A tier is a general
grouping that refers to a position's sensitivity and risk. Sensitivity involves the position's potential
impact on the national security of the United States, and risk involves the position's potential to damage
the public's trust in the federal government. As shown in Figure 1, the previous personnel security
standards had five investigative tiers, but the new continuous vetting process under TW 2.0 will have
three tiers: low, moderate, and high. When the TW 2.0 Program is fully operational, the EPA must
provide TW 2.0-level vetting services to the Agency's entire national security and non-sensitive public
trust populations, as well as TW 1,25-level vetting services to its entire low-risk population.

Continuous Vetting Process at the EPA

Like it is for ail nondefense agencies, the EPA's continuous vetting process is facilitated by the data that
the DCSA collects and reports. As shown in Figure 2, the EPA's process involves continuous review of
data related to the seven types of automated record check areas, with reports being generated by the
DCSA if any data meet the designated alert criteria. If a report is generated, the adjudication process
falls within the EPA's area of responsibility. The PSB conducts personnel vetting for the EPA, and Agency
procedure requires that reports must be logged and, if necessary, adjudication must begin within five
business days.

Figure 2: Scope of the EPA's continuous vetting efforts

Note: Overlay of dotted blue line identifies the EPA's TW 2.0 Program implementation responsibilities.

The EPA's TW 2.0 Program responsibilities begin once an alert is generated by the DCSA's continuous
vetting system, and the subsequent report is provided to the PSB, Likewise, EPA employees are required
to alert the PSB about changes or incidents that may impact their clearances. In either situation, the
PSB's responsibility is to verify any alert and then, based on the employee's security status, adjudicate
whether that alert increases risks sufficiently to require revocation of that security status.

Defining Fair and Effective Personnel Vetting Outcomes

Using the policies outlined in the Federal Personnel Vetting Core Doctrine,3 the Performance
Accountability Council's Executive Agents designed the ODNI's personnel security policies to achieve fair
and effective outcomes. The Executive Agents published the Federal Personnel Vetting Performance
Management Standards in September 2022, which defined fairness and effectiveness in the context of
personnel vetting programs. Specifically, the performance standards establish performance metrics for
agencies to assess the efficiency, effectiveness, and risk of their personnel security programs and policies.
The performance standards also require agencies to develop quality management programs to ensure

3 Federal Personnel Vetting Core Doctrine, 86 Fed, Reg. 2705 (Jan. 13, 2021).

24-E-0020

-------
the fair implementation of their personnel security programs. Until implementation guidance is published
by the Executive Agents, however, agencies are not required to implement the performance standards.

Without the benefit of this guidance and for the purposes of our objective, we assessed fairness and
effectiveness as the extent to which the PSB is on track to achieve full implementation of TW 2.0 by
established milestones and is compliant with the ODNI's TW 2.0 policies and guidance.

The performance standards define fairness in the context of a quality assurance programs:

Fairness: Ensure all personnel vetting processes and procedures comply with
applicable laws, Executive Orders, and policy regarding the collection, use, retention,
and dissemination of protected information.

The performance standards define effectiveness in the context of performance metrics:

Effectiveness: Performance metrics that reflect whether an activity is achieving the
intended result and whether the activity is aligned with intent of Federal personnel
vetting policy. These metrics support achieving quality and desired outcomes.

Responsible Offices

The EPA's PSB conducts personnel vetting for the EPA and is responsible for implementing the TW 2.0
Program. The PSB is housed in the Labor, Suitability, and Conduct Division in the EPA Office of Mission
Support's Office of Human Capital Operations. The PSB determines whether to initially grant a security
clearance to EPA personnel based on information gathered and verified in the initial background
investigation, and it reviews and adjudicates security risks that may arise from the data that it receives
from the continuous vetting process. The fiscal year 2023 budget for the PSB was approximately
$3.4 million, which was 0.03 percent of the EPA's total fiscal year 2023 budget of $10.14 billion.

Scope and Methodology

We conducted this evaluation from May to November 2023 in accordance with the Quality Standards
for Inspection and Evaluation published in December 2020 by the Council of the Inspectors General on
Integrity and Efficiency. Those standards require that we perform the evaluation to obtain sufficient and
appropriate evidence to support our findings.

We reviewed applicable law, policy, and other criteria documents related to the program. We reviewed
the status of the PSB's TW implementation efforts as of October 2023. This included verifying that the
PSB submitted required reports to the Performance Accountability Council's chair and interviewing PSB
personnel to determine whether the Agency met the Performance Accountability Council's TW 1.25 and
1.5 milestones. We also assessed whether the Agency continued to meet ongoing milestones provided
in the quarterly policy updates published by the Performance Accountability Council. We reviewed
procedures adopted by the PSB and collected the necessary documentation and reports to verify the
program's implementation progress. As previously stated in this report, given that the Executive Agents

24-E-0020

6


-------
have designed the personnel security program policies and procedures to be fair and effective, but that
the Executive Agents have not yet published all the required implementation guidance, we assessed
fairness and effectiveness as the extent to which the PSB has achieved TW 1.25 and TW 1.5 milestones
and is on track to achieve full implementation of TW 2.0 by the established milestones.

Prior Reports

Prior to the issuance of this report, we had not reviewed the PSB's TW 2.0 Program implementation
status. The U.S. Government Accountability Office has issued reports on the governmentwide
development and implementation of theTW Program, including:

•	Personnel Vetting: Actions Needed to Implement Reforms, Address Challenges, and Improve
Planning, GAQ-22-104093, which determined that the Performance Accountability Council has
made progress in implementing TW 2.0. The report further stated that the Performance
Accountability Council principals reduced a backlog of investigations, began to develop a policy
framework for a new approach to personnel vetting, and began to develop needed information
technology systems.

•	Personnel Vetting: DOD Needs a Reliable Schedule and Cost Estimate for the National
Background Investigation Services Program, GAQ-23-105670, which found that the lack of a
reliable schedule for implementing the National Background Investigative Services could cause
delays and which recommended that Congress should consider requiring the Department of
Defense to develop a reliable National Background Investigative Services program schedule and
cost estimate based on the Government Accountability Office's best practices.

Results

The PSB met all TW 1.25 and TW 1.5 milestones to fairly and effectively implement the EPA's enhanced
personnel security program in accordance with the ODNI's performance standards. In addition, as of
October 2023, the PSB was meeting all TW 2.0 implementation milestones identified by the Performance
Accountability Council's policies and guidance and was on track to meet the full TW 2.0 implementation
milestone of March 30, 2026. At the time of our review, the PSB had eight staff to implement the TW 1.5
requirements, which provide for continuous vetting services for the EPA's approximately 1,100 national
security population. As additional TW 2.0 implementation requirements come into effect, which will
require the PSB to expand its services to continuously vet the Agency's entire population of nearly 22,000
employees, the EPA will need to proportionally increase the PSB's implementation capacity. Without
adequate implementation capacity, the PSB may not be able to adjudicate continuous vetting alerts
effectively or in a timely manner, putting national security at risk to insider threats.

The PSB Successfully Met TW 1.25 and 1.5 Milestones and Is on Track to Meet
TW 2.0 Requirements

The PSB met all TW 1.25 and TW 1.5 milestones to fairly and effectively implement the enhanced

Agents required that agencies develop TW implementation plans, report on enrollment metrics for
TW transitional steps, certify their compliance with minimum standards, and meet enrollment
milestones. As evidence that it successfully met these requirements, the PSB provided us with its
TW implementation plan, its correspondence to the ODNI containing quarterly reports of its enrollment
metrics, and the self-certification of its compliance with TW 1.25 and TW 1.5 minimum standards and
enrollment milestones. Additionally, on October 17, 2022, the ODNI concurred with the PSB's
self-certification and issued a memorandum affirming that the Agency met the minimum standards for
TW 1.5. Table 1 lists the key TW implementation milestones and shows the EPA's progress in meeting
those milestones.

* These dates were identified in the June 2023 strategy update only by month and year, such as "May 2023." We
interpret those milestone dates as the last day of the month.

As of October 2023, the PSB was on track to meet the final TW 2.0 implementation requirements by the
March 30, 2026 milestone issued by the Performance Accountability Council. The PSB had already
adopted the applicable ODNI policies, procedures, and managerial processes necessary to fully
implement the TW 2.0 requirements. In addition, the PSB was meeting the interim milestone
requirements outlined in the quarterly updates to the Trusted Workforce 2.0 Implementation Strategy,
including the milestones provided in the September 2023 update. For example, the PSB stated that it
completed the transition to using eApplication, an automated system for initial background checks of
new employees. However, the PSB informed us that the eApplication software system can be unstable
so when processing issues occur, the PSB must revert to using the Electronic Questionnaires for
Investigations Processing system, the legacy automated application program.

The PSB also informed us that, while it completed transferring the necessary data to fully enroll the
applicable employee populations into the Record of Arrest and Prosecution Back system to the DCSA as
of September 28, 2023, the DCSA was experiencing delays in fully processing and uploading the data to
the National Background Investigative Services system. While continuous vetting for the EPA's
non-sensitive public trust and low-risk populations is not required until September 30, 2025, and
March 30, 2026, respectively, the PSB plans to manage the continuous vetting needs for these
non-national security populations the same way as it does for the Agency's national security population.
Providing this level of service, however, will not be possible if the required system tools are unstable or
are not fully available for agencies to use by those key milestone dates.

The PSB Must Increase Its Implementation Capacity to Mitigate Risk of
Processing Delays

As of October 2023, the PSB had eight employees who are appropriately trained to adjudicate
continuous vetting alerts in a timely manner. The PSB's workload is expected to significantly increase as
TW 2.0 becomes fully implemented due, in part, to the large volume of personnel data that must
undergo adjudication within five business days, as required by EPA procedure.

On September 30, 2022, the PSB team began operating under TW 1.5 requirements to provide
continuous vetting services for the EPA's approximately 1,100 national security population employees.
When TW 2.0 is fully implemented, the PSB will also be responsible for providing some level of
continuous vetting for 100 percent of all EPA staff, including employees occupying non-sensitive public
trust and low-risk positions. To put this in perspective, on August 25, 2023, the PSB stated that there
were 16,429 employees occupying non-sensitive public trust positions and 4,270 employees occupying
low-risk positions. This means that, if full TW 2.0 implementation would take effect immediately, the
PSB would have to provide continuous vetting services for 21,799 individuals—a 20-fold increase from
TW 1.5 requirements.

As shown in Figure 3, the EPA's most significant continuous-vetting population increase occurs from
September 30, 2022, through September 30, 2024, at which time the PSB must be providing
TW 1.5-level vetting services to the 1,100 national security employees, as well as have enrolled and be
providing TW 1.25-level vetting services to all 16,429 non-sensitive public trust employees. However, in
18 months, from September 30, 2024, to March 30, 2026, the EPA must also significantly increase the
level of continuous vetting services it provides. Specifically, by September 30, 2025, the PSB must be
providing the full TW 2.0-level vetting services to all 17,529 national security and non-sensitive public
trust employees, in addition to enrolling 50 percent of the low-risk employees in TW 1.25-level vetting
services. When the TW 2.0 Program is fully operational on March 30, 2026, the PSB must have enrolled
the remaining 50 percent of low-risk employees in TW 1.25-level vetting services.

-------
These service population increases mean that the PSB will need to have sufficient resources, including
any additional staff and equipment, in place to enroll and begin providing continuous vetting services for
each of the implementation phases. As final TW 2.0 implementation is achieved, the Agency must
expand its continuous vetting capacity to keep pace with both the increasing numbers of employees
enrolled for continuous vetting services, and the level of services provided to those employees.

The most significant challenge to the PSB achieving full TW 2.0 implementation is developing sufficient
capacity to effectively implement all the TW 2.0 requirements once they come into effect. While the
largest number of enrollments into the system must occur by the September 30, 2024 milestone, the
increase in required service levels between September 30, 2024 and the final March 30, 2026 milestone
will likely cause the most significant need for additional staff effort and resources. The PSB informed us
that, between October 2022 and July 2023, it had adjudicated roughly 3,000 self-reported alerts for the
national security population of nearly 1,100 employees. If that number of continuous vetting alerts is
consistent for all employees, the PSB would need to address and adjudicate as many as 60,000
continuous vetting alerts per year after full TW 2.0 implementation. The PSB team said that additional
alerts from a larger population would exponentially increase their workload. Without sufficient capacity
to respond to the increase in enrolled populations and, subsequently, the expected increase in
adjudication services needed, the PSB could experience delays in processing and managing full TW 2.0
implementation, which may increase the risks to national security from insider threats.

Recommendation

We recommend that the assistant administrator for Mission Support:

1. Develop a plan for how the Personnel Security Branch will achieve the capacity necessary to
meet the requirements of full Trusted Workforce 2.0 implementation.

Agency Response and OIG Assessment

The Office of Mission Support agreed with our recommendation and described its planned corrective
action to develop a plan and associated guidance documents to meet full TW 2.0 requirements. The
Agency's response noted, however, that its capability to achieve capacity for "TW 2.0 success is
dependent on various capabilities to which other government agencies, namely the Defense
Counterintelligence and Security Agency, have not released for use currently." Based on this
information, and as the Agency awaits the final updated Trusted Workforce 2.0 Implementation
Strategy, the EPA provided an acceptable planned corrective action and estimated milestone date.
We consider the recommendation resolved with corrective action pending. Appendix A contains the
Agency's response to the draft report.

Programs, Offices, and Centers Oversight
Office of Special Review and Evaluation

Thank you for the opportunity to respond to the issues and recommendation in the subject
evaluation draft report. Following in a summary of the agency's overall positions, along with its
position on the report's recommendation. The Office of Mission Support agrees with the
recommendation outlined in the Office of Inspector General's Draft Report and has developed
one corrective action to address it.

AGENCY'S OVERALL POSITION

The agency agrees with the recommendation and will develop a plan in accordance with timely
Trusted Workforce 2.0 Implementation Strategy documents and associated guidance.

The agency has faced challenges with implementing Trusted Workforce 2.0 (TW 2.0)
requirements given that the government-wide objectives and metrics have shifted repeatedly
since 2018. The Performance Accountability Council (PAC) introduced TW 2.0 in 2018 and initially
targeted full TW 2.0 implementation by end of Fiscal Year 2024. In June 2023, the PAC extended
the full TW 2.0 implementation date to March 30, 2026 via the June 2023 Trusted Workforce
Implementation Strategy. Since the June 2023 Trusted Workforce Implementation Strategy, the
PAC issued the September 2023 Trusted Workforce 2.0 Implementation Strategy which provided

24-E-0020	13


-------
updated milestone objectives related to successful implementation of TW 2.0. The agency
routinely receives updated quarterly Trusted Workforce 2.0 Implementation Strategy
documents which update milestone objectives. A commonality within the quarterly updates is
the statement of, "Updated milestone dates with greater precision and marked completed
tasks," with the reason of, "To better enable implementation planning and reflect progress."

As notated within OIG's draft report "The EPA's Enhanced Personnel Security Program Is on
Track, but Challenges to Full Implementation Remain," the Defense Counterintelligence and
Security Agency (DCSA) is the agency's investigative service provider and is providing personnel
vetting services through the National Background Investigative Services (NBIS) system. DCSA's
NBIS system is not fully operational and the capability to enroll public trust personnel within
continuous vetting has not been released for agency use. NBIS's capabilities not being fully
deployed hinders the agency's ability to meet the milestone objective of "begin enrolling non-
sensitive public trust population into TW 1.25" by the target date of October 2023, as the
capability has not been released for the agency's use. The agency is operating at a
disadvantage due the NBIS's delayed deployment of capabilities necessary to enroll the non-
sensitive public trust population into continuous vetting.

EPA's capability to develop a plan to achieve capacity to meet Trusted Workforce 2.0
requirements (pursuant to OIG's recommendation) is contingent on PAC's and DCSA's final
implementation requirements. Due to continuously changing and quarterly updated milestones
within Trusted Workforce 2.0 Implementation Strategy documents and unreleased NBIS system
capabilities, the agency will continue to assess Trusted Workforce 2.0 (TW 2.0) requirements
and NBIS developments to plan accordingly to meet milestone objectives. TW 2.0 success is
dependent on various capabilities to which other government agencies, namely the Defense
Counterintelligence and Security Agency, have not released for use currently. The agency is
expecting an updated Trusted Workforce 2.0 Implementation Strategy that will adjust
milestone objectives consistent to the various updated Trusted Workforce 2.0 Implementation
Strategy the agency has received since the initiation of TW 2.0.
