At a Glance
Why We Did This Project
We conducted an audit of the
U.S. Environmental Protection
Agency's (EPA's) contract
billing controls for EPA
Contract No. EP-W-11-019,
Task Order 12, which was
awarded in 2011. This audit
was initiated in response to an
anonymous hotline complaint
regarding possible irregularities
with contract invoicing and
payments.
The purpose of this audit was
to determine whether the EPA's
contract administration of EPA
Contract No. EP-W-11-019,
Task Order 12, had effective
controls over billing and funding
to prevent fraud, waste and
abuse. Although the contract
ended in 2017, the contract is
open until the indirect rates are
finalized and related cost
differences are paid.
This report addresses the
following:
• Operating efficiently and
effectively.

Contract Management Controls

OIG WEBCOMMENTS@epa.oia.
List of OIG reports.
What We Found
Contract management controls were insufficient
for expired EPA Contract No. EP-W-11-019.
We identified the following issues:
All 11 invoices tested
did not comply with
contract requirements.
•	Required contractor performance reports were not finalized.
•	There were no official contract or task order modifications for some of the
Contracting Officer and Contracting Officer's Representative changes.
•	Contracting Officer's Representative appointment memorandums were
missing.
•	Contracting Officers did not perform required periodic invoice reviews.
The issues occurred due to various reasons, such as staffing issues, high
turnover within the EPA's Office of Acquisition Solutions (i.e., multiple contracting
officers during the contract), contract management file disorganization, and
inadequate oversight. As a result, there was a lack of available contractor
performance information, reduced accountability for the EPA's contract
management responsibilities, an increased risk of unauthorized acts, and a
reduced assurance that costs were billed in accordance with contract
requirements.
Also, the invoices for Task Order 12 did not comply with specific contract
requirements to manage the task order effectively. Despite requirements for
invoices to be thoroughly reviewed prior to payment, the invoices reviewed under
Task Order 12 were not adequately reviewed and documentation of any reviews
prior to approval, such as completed invoice review checklists, did not exist. As a
result, the EPA did not have reasonable assurance that costs or a fee billed
under Task Order 12 were allowable, allocable and reasonable. Our limited
review of invoices under Task Order 12 found that a subcontract fixed fee totaling
$5,158.29 was overbilled.
Recommendations and Planned Agency Corrective Actions
This report makes seven recommendations to the Assistant Administrator for
Mission Support. Most of our recommendations require actions to improve
contract management, internal controls and oversight. We make no
recommendations related to some of the findings in this report because the
contract has expired.
The EPA concurred with all seven recommendations. The EPA's proposed
corrective actions and planned completion dates meet the intent of the
recommendations. The EPA completed corrective actions for two
recommendations; the other five are resolved with corrective actions pending.

Chapter 1
Introduction
Purpose
The Office of Inspector General (OIG) of the U.S. Environmental Protection
Agency (EPA) conducted this audit to determine whether the EPA's contract
administration of EPA Contract No. EP-W-11-019, Task Order 12, had effective
controls over billing and funding to prevent fraud, waste and abuse.
Background
The OIG audited the EPA's contract billing controls for EPA Contract No. EP-W-
11-019, Task Order 12, which was awarded in fiscal year (FY) 2011 to Systems
Research and Applications Corporation, located in Fairfax, Virginia. This audit
was initiated in response to an anonymous hotline complaint regarding possible
irregularities with contract invoicing and payments. The contract provided the
EPA with a broad range of information technology and information management
technical and professional services. The contract is an indefinite-delivery/
indefinite-quantity contract, and Task Order 12 is a cost-plus-fixed-fee task order.
After a merger with Computer Sciences Corporation in November 2015, the
contract continued under the name CSRA Inc. The contract had a contract award
value of almost $100 million and over $1.2 million was billed under Task Order 12.
Contracting Staff Roles and Responsibilities
A Contracting Officer (CO) is a federal employee who has the authority to enter
into and administer contracts. COs are responsible for the performance of all
necessary actions for effective contracting, enforcing compliance with the terms
of the contract, and safeguarding the interests of the United States in its
contractual relationships.
A Contracting Officer's Representative (COR) is the authorized representative of
the CO. A COR is a federal employee nominated by a supervisor and appointed in
writing by the CO to assist with the technical monitoring or administration of a
contract. Additionally, a Task Order Contracting Officer's Representative
(TOCOR) was appointed because EPA Contract No. EP-W-11-019 used task
orders. As the CO's primary representative, the contract-level COR oversees the
TOCORs. Under this contract, the TOCORs generally approved invoices.

-------
Responsible Offices
In November 2018, during our audit, the EPA combined the Office of
Administration and Resources Management and the Office of Environmental
Information (OEI) to form the Office of Mission Support (OMS). The OMS is
responsible for implementing the recommendations in this report through the
following offices:
•	The Office of Acquisition Solutions (OAS) issues policies and procedures,
manages operations, and supports the agency's procurement and contracts
management program from contract planning through closeout.
•	Environmental Information Offices (formerly OEI) are to securely deliver
quality information, technology and services to advance the overall EPA
mission to protect human health and the environment.
Scope and Methodology
We conducted this performance audit from March 2018 through February 2019
in accordance with generally accepted government auditing standards. Those
standards require that we plan and perform the audit to obtain sufficient,
appropriate evidence to provide a reasonable basis for our findings and
conclusions based on our audit objective. We believe that the evidence obtained
provides a reasonable basis for our findings and conclusions based on our audit
objective.
To obtain an understanding of the contractual and acquisition requirements and
internal controls, we reviewed the following documentation:
•	Hotline referral.
•	Contract terms and conditions.
•	Task Order 12.
•	Contract and Task Order 12 modifications.
•	F ederal Acqui siti on Regul ati on (FAR).
•	EPA Acqui siti on Regul ati on.
•	EPA Acquisition Guide (EPAAG).
•	Internal OAS guidance documents related to contract management.
•	Prior audit reports relevant to our audit objective.
•	Internal control assessment reports from the Federal Managers' Financial
Integrity Act.
•	Roles and responsibilities within the EPA's contract management structure.
To determine whether the EPA's contract administration of Task Order 12 had
effective controls over billing and funding to prevent fraud, waste and abuse, we
performed the following actions:
19-P-0157

-------
•	Interviewed the OAS Team Lead, the CO, the contract-level COR, the
TOCOR for Task Order 12, and the then OEI manager.
•	Reviewed a judgmental sample of 11 of 64 invoices for Task Order 12 and
tested them for compliance with contract terms and conditions. Our
sample concentrated on the time period highlighted in the original hotline
complaint. See Table 1 for details.
•	Based on the fixed fee calculation errors on the 11 invoices reviewed, we
reviewed the fixed fees billed on all 64 invoices and calculated the total
amount of a fixed fee overbilled under Task Order 12.

Prior Audit Coverage
EPA OIG Report No. 18-P-0231. Without E-Invoicing and Stronger Payment
Process Controls, EPA Is Placing $1.2 Billion at Risk Annually, issued
August 16, 2018, found that the EPA can maximize the efficiency of its contract
invoice payment process by focusing on four areas:
•	Implementing an electronic invoicing (e-invoicing) system.
•	Addressing administrative and contract modification processing errors.
•	Taking prompt payment discounts offered on contract invoices.
•	Performing critical CO and COR oversight duties.
The report stated that agency COs and CORs could not provide or locate
documentation demonstrating the performance of their oversight duties. As of
February 13, 2019, the agency reported that not all corrective actions for the
recommendations had been completed.
EPA OIG Report No. 17-P-0380. EPA's Alternative Dispute Resolution and
Public Involvement Contract Needs Better Management, issued
September 12, 2017, found that management of EPA Contract No. EP-W-14-020
needed to improve to comply with contractual and acquisition requirements. For
example:
•	The CO did not perform invoice reviews in a timely manner as required by
the EPAAG.
19-P-0157

been completed.
EPA OIG Report No. 16-P-0078. EPA's Background Investigation Support
Contracts and OPMBillings Need Better Oversight and Internal Controls, issued
December 14, 2015, found that the EPA did not monitor the support contract for
compliance with contract terms and conditions. The report found that:
•	The COs did not perform invoice reviews.
•	The COR did not maintain proper contract documentation.
The agency reports that corrective actions for all of the recommendations have
been completed.

Chapter 2
Expired EPA Contract No. EP-W-11-019 Had
Insufficient Contract Management Controls
Contract management controls were insufficient for expired EPA Contract
No. EP-W-11-019. We identified the following issues during our audit:
•	Required contractor performance reports were not finalized.
•	There were no official contract or task order modifications for some CO
and COR changes.
•	COR appointment memorandums were missing.
•	COs did not perform required periodic invoice reviews.
The issues occurred due to various reasons, such as staffing issues, high turnover
within the OAS (i.e., multiple COs during the contract), contract management file
disorganization, and inadequate oversight. As a result, there was a lack of
available contractor performance information, reduced accountability for the
EPA's contract management responsibilities, an increased risk of unauthorized
acts, and a reduced assurance that costs were billed in accordance with contract
requirements.
Contractor Performance Assessment Reporting System Reports Were
Not Finalized
Contract Section H.7 states that the CO shall complete a Contractor Performance
Assessment Reporting System (CPARS) report within 90 business days after the
end of each 12 months of contract performance (interim report) or after the last
12 months (or less) of contract performance (final report).
FAR 42.1502(a) states:
Past performance evaluations shall be prepared at least annually
and at the time the work under a contract or order is completed. ...
Past performance information shall be entered into CPARS, the
Governmentwide evaluation reporting tool for all past performance
reports on contracts and orders.
FAR 42.1503(f) states:
Agencies shall prepare and submit all past performance evaluations
electronically in the CPARS at http://www.cpars. gov/.
19-P-0157
5

-------
The OAS team lead provided CPARS reports for FYs 2014, 2015 and 2016. The
FY 2016 CPARS report for the period of performance ending January 31, 2016,
shows a status of "Incomplete-Initiated," meaning it was never finalized. Also, the
FY 2016 CPARS report was the last one initiated, even though the contract was
extended to January 31, 2017. Based on explanations provided by the contract-
level COR and CO, we concluded that not finalizing the FY 2016 CPARS report
and not completing the FY 2017 report was an oversight.
Delayed Reporting Hinders Access to Contractor Performance
Information
Delayed CPARS reporting has the following potential effects:
•	It reduces the ability of both internal and external source selection officials
and others involved in the acquisition process to obtain access to sufficient
contractor performance information.
•	It hinders improvement in government acquisition practices.
In response to our discussion document issued to the agency on September 28,
2018, the OAS plans to re-emphasize the critical importance of performing
CPARS responsibilities in accordance with applicable laws, the FAR, and agency
regulations and policies. The OAS will accomplish this by issuing a memorandum
that addresses the responsibilities of OAS Division Directors and Regional
Acquisition Managers.
Recommendations
We recommend that the Assistant Administrator for Mission Support:
1.	Require the Office of Acquisition Solutions to issue a memorandum to its
Division Directors and Regional Acquisition Managers emphasizing the
importance of their contractor performance reporting responsibilities.
2.	Establish internal controls to verify that all required Contractor
Performance Assessment Reporting System reports are finalized.
Complete fiscal years 2016 and 2017 reports for the contract audited.
Agency Response and OIG Evaluation
The agency concurred with Recommendation 1 and completed corrective action on
March 25, 2019. On that date, the OAS Director, who is the Senior Procurement
Executive, issued an email memorandum to OAS Division Directors and Regional
Acquisition Managers. The memorandum emphasized the importance of their
contractor performance reporting responsibilities. The agency's corrective action
19-P-0157
6

-------
meets the intent of Recommendation 1. The OIG considers Recommendation 1
completed.
The agency concurred with Recommendation 2 and provided a corrective action
plan with a milestone date of June 28, 2019. The agency's proposed corrective
actions and planned completion date meet the intent of Recommendation 2. The
OAS will re-emphasize the verification of timely CPARS completion during the
conduct of internal control assessments. The OAS contracting office with
cognizance (responsibility) over the audited contract will be required to submit a
supplement to its Contract Management Assessment Program's Internal Control
Plan to the OAS Deputy Director. The supplement must provide a detailed plan to
consistently address and execute the timely completion of CPARS. The CO
assigned throughout the contract closeout will be assigned to review any
incomplete reports that still need to be finalized in accordance with FAR
42.1502(a) and EPAAG subsection 42.15.1.
There Were No Contract Modifications Issued for Some CO and COR
Changes
Based on the FAR, changes in administrative contract staff, such as COs and
CORs, are administrative changes requiring the issuance of a modification to the
contract or task order:
•	FAR 43.101 states that "Administrative change" means a written,
unilateral contract change that does not affect the rights of the parties.
•	FAR 43.103(b) states that a unilateral modification is a contract
modification signed only by the contracting officer.
•	FAR 43.103(b)(1) states that unilateral modifications are used to make
administrative changes.
There were multiple COs while the contract was active. However, there were no
official contract modifications for some of the CO changes. In addition, there was
no task order modification to change the TOCOR for Task Order 12 to the
contract-level COR.
The lack of contract modifications for administrative changes in COs is due to
staffing issues, high turnover within the OAS, contract management file
disorganization and inadequate oversight. As a result, there is incomplete contract
documentation to identify the responsible administrative contract staff. This
hinders accountability for the EPA's contract management responsibilities.
In response to our discussion document, the OAS stated that it is currently
experiencing staffing issues that impact and pose challenges to its operations,
including the processing of modifications. To keep up with work demands, the
19-P-0157
7

-------
OAS indicated that its components have used matrixing techniques where staff
are "tasked" across the various OAS branches to allow for a more efficient use of
time and resources.
The processing of administrative actions on contracts or task orders may be
performed by any available warranted CO and does not generally require issuing
an administrative modification to replace or rename a permanent CO. However,
the OAS concurred that when a contract or task order is permanently moved from
one division to another or from one branch to another, or when a particular CO
will administer a contract/task order for a reasonably extended amount of time, a
contract/task order modification must be issued. The modification is included in
the official file to maintain stability and clearly identify which CO, branch and
division is ultimately responsible and accountable for the contract or task order.
Recommendation
We recommend that the Assistant Administrator for Mission Support:
3. Issue a contract modification to identify the responsible Contracting
Officer through contract closeout.
Agency Response and OIG Evaluation
The agency concurred with Recommendation 3 and completed corrective action
on May 8, 2019. On that date, the agency issued a contract modification to assign
the responsible CO through contract closeout.
COR Appointment Memorandums Were Missing
FAR 1.602-2(d) requires that COs, in accordance with agency procedures,
designate and authorize in writing a COR for all contracts other than firm-fixed-
price contracts, unless the CO retains and executes the COR duties.
EPAAG 1.6.5 describes a TOCOR as a task order COR appointed by the CO who
may receive the same authority as the COR. In addition, EPAAG requirements for
documenting a COR or TOCOR appointment memorandum include the
following:
•	EPAAG 1.6.5.5(a) states that "the CO shall appoint a certified COR on all
contracts, purchase orders, work assignments, and delivery/task orders
greater than the simplified acquisition threshold."
•	EPAAG 1.6.5.5(d) states that "the CO shall specify the COR's
responsibilities in a COR appointment memorandum."
19-P-0157
8

-------
•	EPAAG 1.6.5.6(b) (10) states that "the COR shall maintain a file for each
assigned contract."
•	EPAAG 1.6.5.6(b) (10) (iii) states that the file must include "a copy of the
CO's appointment memorandum of designation describing the COR's
duties and responsibilities."
•	EPAAG 1.6.5.10(d) (13) states that "the CO shall maintain a signed copy
of each COR's Nomination Form, Appointment Memorandum, and all
other appointment notification letters in the official contract file."
The EPA was unable to find the COR nomination or appointment memorandums
for either the contract-level COR or the TOCOR for Task Order 12. The lack of
COR appointment memorandums appears to be due to an oversight.
For example, the OAS team lead stated that "this contract has been passed around
so much and these [memorandums] are not in the file. When someone inherits a
contract, the person should review everything. This did not happen."
In another instance, when the CO was asked if the appointment/nomination
memorandums existed, he stated that "if they exist, they would be in the official
paper files"; however, none were present. The CO also stated, "there was some
disorganization with the CO changes, moving to the EPA Acquisition System,
and we moved twice."
In addition, the contract-level COR stated that that the COR "did not know where
to find anything from the contract."
Lack of COR Appointment Memorandums Increases the Risk of
Unauthorized Acts
Without COR appointment memorandums, the COR/TOCOR performed contract
functions without the proper authority to act on behalf of the CO. Without an
appointment memorandum, the contractor and COR may not know the extent and
limitations of the COR's authority and may not be familiar with the requirements
of the contract. The lack of COR appointment memorandums increases the risk
that the COR could be held personally liable for unauthorized acts.
Note: We make no recommendation related to this finding because the contract
has ended.
Contracting Officers Did Not Perform Periodic Invoice Reviews
EPAAG 32.9.1.5(b)(4) states that "the responsibility for invoice review and
approval is first vested with the CO, but with the CO's approval, may be
delegated to the COR." However, even if invoice approval is delegated to the
19-P-0157
9

-------
COR, the CO is still required to perform periodic invoice reviews. Both EPAAG
32.9.1.5(b)(4) and the OAS Invoice Review & Approval Desk Guide state:
A CO's periodic monitoring must include at least one detailed
review of a contract invoice for each contract year. However, for
many contract types one review may not be sufficient. In these
instances, if more frequent monitoring is required to ensure proper
invoice approval, the CO must conduct additional invoice reviews.
The CO has the ultimate responsibility and accountability for
invoice processing under individual contracts. It is highly
recommended that the CO perform these reviews at least quarterly,
or more frequently as needed.
There is no supporting documentation or evidence in the contract files of any
periodic CO invoice reviews, as required by the OAS Invoice Review & Approval
Desk Guide. The lack of periodic CO invoice reviews occurred for various
reasons, such as staffing issues, high turnover within the OAS (i.e., multiple COs
during the contract), and contract management file disorganization.
Without the required CO invoice reviews, the EPA did not provide necessary
assurance that costs were billed in accordance with contract requirements. Had the
CO performed the required invoice reviews, some of the noncompliant invoices
(e.g., invoices missing required data or invoices with incorrect indirect rates or
fees) may have been detected (see Chapter 3).
Note: We make no recommendation related to this finding because the contract
has ended.
19-P-0157

Chapter 3
Inadequate Invoice Reviews Resulted in
Noncompliant Invoices that Were Not Detected
Invoices for Task Order 12 did not comply with specific contract requirements to
manage the task order effectively. Despite requirements for the invoices to be
thoroughly reviewed prior to payment, the invoices reviewed under Task Order 12
were not adequately reviewed and documentation of any reviews prior to
approval, such as completed invoice review checklists, did not exist. As a result,
the EPA did not have reasonable assurance that the costs or fees billed under Task
Order 12 were allowable, allocable and reasonable. Our limited review of
invoices under Task Order 12 found a total of $5,158.29 for an overbilled
subcontract fixed fee.
EPA Requires Thorough and Documented Contract Invoice Reviews
EPAAG 32.9.1.5(a) states:
It is the policy of the government to review invoices thoroughly
for cost reasonableness and to process invoice submittals in a
timely manner. Adherence to this policy will result in payment
of costs which are allowable, allocable, and reasonable, and avoid
interest penalties due to late payment of such costs. Approving
officials involved in invoice reviews must (1) review contract
invoices thoroughly, (2) process invoices in a timely manner, and
(3) maintain records of their invoice reviews and actions taken as a
result of the reviews. It is important that invoice charges be closely
examined and contractor costs questioned, suspended, or
disallowed, when appropriate.
Similarly, the OAS Invoice Review & Approval Desk Guide states:
It is EPA's policy to review invoices thoroughly to ensure
that adequate information, proper rationale, and documentation
exists to support payment of contractor invoices in a timely
manner. Adherence to this policy will result in payment of costs
which are allowable, allocable, and reasonable. ... All CORs
must document in their files that invoice reviews were performed.
A file of all invoices, monthly progress reports, invoice review
checklists, and all other documentation associated with the
reviews must be maintained for the life of the contract or
applicable records retention requirements, whichever is longer.
19-P-0157
11

-------
The guide is silent on whether TOCORs are required to use the TOCOR "Checklist
for Invoice Review" when reviewing and approving task order invoices. However,
even if the use of the checklist is not required, we believe that the checklist is a good
internal control tool to use when reviewing and approving invoices. The checklist
also serves as supporting documentary evidence that a review was performed.
EPAAG 1.6.5.14(a) states:
This section concerns the removal of a COR from all Agency
contracts for cause, such as performance or conduct reasons.
The OAS Director may permanently remove a COR's eligibility
to serve on all Agency acquisitions for: (1) Violation of Federal
or Agency acquisition regulations and/or policies; or (2) Failure
to comply with Standards of Ethical Conduct for Employees of
the Executive Branch.
Invoices Did Not Comply with Contract Terms and Conditions
All 11 invoices reviewed did not comply with contract requirements. We found
the following:
• Per contract section B.l(f), the subcontractor fee should only be
6 percent, but the contractor billed an 8-percent fee on the entire
invoice for three of the 11 invoices tested. Based on the findings for
the three invoices tested, we reviewed all Task Order 12 invoices with
subcontract labor. The contractor charged 8 percent instead of 6 percent on
subcontractor costs. In later invoices, the contractor tried to correct the
problem but did not provide any detail in the invoice as to how or why the
fixed fee was adjusted. We calculated the 2-percent fixed fee overbilled.
We also provided credit for all the unknown adjustments the contractor
made on later invoices. We then calculated a fixed fee overbilling of
$5,158.29. See Table 2 below for details.

a Invoice 52 fixed fee was excluded as the invoice was not

• Billed indirect costs did not match the approved rates for all
11 invoices tested. In addition, there was insufficient information
regarding the base to apply to each of the indirect rates to determine the
indirect costs that should have been billed.
19-P-0157

-------
•	For all 11 invoices tested, the invoices did not include the details
required for indirect costs (e.g., the rate and the base to apply to the
indirect rates). This is required per the contract's invoice preparation
instructions.
•	Unexplained differences occurred in direct contractor labor rates for
eight of the nine invoices with labor charges. No explanation was
provided for the fluctuation in labor rates for the same contract staff.
•	Invoices combined subcontractor and contractor direct labor to
calculate total direct labor. This was misleading and made the invoices
more difficult to review. The subcontract labor had to be removed from
direct labor to calculate contractor's indirect expenses and a separate fixed
fee.
•	Per contract section F.2, noncompliance occurred with monthly
progress report requirements for all nine regular monthly invoices
tested. Two invoices tested would not require a progress report because
they were indirect rate adjustments. The other nine invoices tested should
have provided additional information to support the indirect calculations
included in the final approved indirect rates, the base for the period of the
applicable rates, the billed indirect rates and the reconciliation. The EPA
did not receive some of the required information needed to manage the
task order effectively because of incomplete monthly progress reports.
During our review of the 11 invoices, we noted that Invoice 51 was paid over
20 months after submission. The TOCOR did not approve the invoice due to
inadequate support in November 2015. After the then OEI manager removed the
TOCOR from the project, the contract-level COR incorrectly approved the
original invoice in August 2017 for $6,269. The contract states that when an
original voucher is submitted but not paid the resubmission should be a separate
invoice showing the original voucher number and designated with the letter "R,"
along with a copy of the removal of suspension notice and appropriate
supplemental schedules. The resubmission of this voucher did not designate the
letter "R," update the date, explain the suspension removal or include the
supplemental schedules per the contract requirements.
Lack of Invoice Review and Supporting Documentation
Multiple causes contributed to the noncompliant invoices:
•	There was no supporting documentation for Task Order 12 invoice
reviews prior to approval, such as completed invoice review checklists.
•	The TOCOR felt pressured by the then OEI manager to pay the contractor.
After the manager informally removed the TOCOR for not paying the

-------
invoices that lacked adequate support, the manager requested the contract-
level COR to pay the invoices.
• The contract-level COR was not familiar with the OAS desk guide for
reviewing invoices. The contract-level COR stated that they paid invoices
based on the request from the then OEI manager and they did not review
anything prior to invoice approval other than making sure there was
sufficient funding to pay the invoice.
Lack of Assurance that Costs Were Allowable
As a result of the lack of invoice review by the COR and TOCOR, the EPA does
not have reasonable assurance that the billed costs and fee are allowable, allocable
and reasonable. Our limited review noted $5,158.29 for an unallowable fixed fee
billed and paid by the EPA. However, without adequate review of all invoices
submitted under Task Order 12, the EPA does not know whether there are further
unallowable costs that it has paid for under the task order.
In response to our discussion document, the OAS stated that it would investigate
and determine whether the contractor overbilled the EPA and whether the EPA
overpaid the contractor. The OAS also stated that all contract/task order actions
that are required to be closed out must be reviewed and documented using a
contract closeout checklist from the EPAAG. The contractor will be required to
comply with all contract terms and conditions. Since Task Order 12 is a cost-type
contract, a final audit (whether formal audit or desk review) is performed and all
questioned costs must be resolved.
Recommendations
We recommend that the Assistant Administrator for Mission Support:
4.	Require the contractor to refund the $5,158.29 fixed fee overbilled to the
EPA under Task Order 12.
5.	Prior to contract closeout, review all Task Order 12 invoices to verify that
costs billed on the contract (e.g., indirect costs) are allowable. Report any
improperly paid costs to the EPA's Office of Inspector General and recoup
overpayments.
6.	Revoke the certification of the contract-level Contracting Officer's
Representative responsible for paying invoices without adequate review.
7.	Investigate the circumstances surrounding the then Office of
Environmental Information manager involved with these contract
transactions and determine whether the manager's actions were
appropriate. If not, implement appropriate actions.
