Why We Did This Review
We conducted this review to
determine whether U.S.
Environmental Protection
Agency (EPA) controls ensure
that invoiced contractor costs
are properly supported and
allowable in accordance with
the Federal Acquisition
Regulation.
Background
In 2008, EPA paid
contractors $1.3 billion. To
safeguard EPA funds, invoices
must be reviewed to determine
whether the submitted costs
are allowable, allocable, and
reasonable.
Contractor Invoice Internal Controls
Need Improvement
What We Found
EPA should improve its invoice review procedures to ensure costs are allowable
and supported in accordance with the Federal Acquisition Regulation. During our
review, we found (1) invoice reviews were not always documented as required by
the Contracts Management Manual (CMM), (2) Project Officer reviews were
based on incomplete information, (3) monthly progress reports did not always
contain the information needed to evaluate invoices, and (4) Agency staff did not
perform required rate verifications and math checks. Some responsible for invoice
reviews were unaware of the guidance and checklists in the CMM, did not
understand the level of documentation needed to review invoices, or did not
adhere to the guidance.
EPA's Office of Acquisition Management (OAM) Financial Monitoring Reviews
(FMRs) have identified repetitive findings related to contractor invoices. The
FMRs continue to find errors in invoices that should have been identified when
EPA employees reviewed the invoices prior to approval for payment. EPA did not
develop a corrective action plan to address invoice review internal control
weaknesses identified in FMR findings that were applicable across multiple
contracts. Instead, FMR findings are resolved on a case-by-case basis.
By not using information on trends identified in the FMR process to improve its
policy and procedures, and without adequate controls over the invoice review
process, the Agency is vulnerable to fraud, waste, abuse, and mismanagement of
the funds that it has a fiduciary responsibility to safeguard.

What We Recommend
We recommend that the Assistant Administrator for Administration and Resources
Management require OAM to modify the CMM to require use of the checklist for
invoice reviews, and have Contracting Officers verify compliance with the policy
during invoice reviews. Further, OAM should take corrective actions in response
to the trends identified in the FMR reviews. EPA agreed with the findings and
provided corrective action plans for addressing all but one of the recommendations
in the report.

Chapter 1
Introduction
Purpose
To safeguard U.S. Environmental Protection Agency (EPA) funds paid to
contractors, EPA employees must review invoices to determine whether the
submitted costs are allowable, allocable, and reasonable. Due to the importance
of invoice review, we conducted this audit to determine whether EPA controls
ensure that invoiced costs are properly supported and allowable in accordance
with the Federal Acquisition Regulation (FAR).
Background
During Fiscal Year 2008, EPA spent $1.3 billion to procure goods and services
from contractors. As defined in FAR Part 31.2, a cost is allowable only when it is
(1) reasonable, (2) allocable, and (3) complies with standards promulgated by the
United States Office of Management and Budget's (OMB 's) Cost Accounting
Standards Board or generally accepted accounting principles and practices
appropriate to the circumstances, terms of the contract, and any limitations set
forth in the FAR. A cost is reasonable if, in its nature and amount, it does not
exceed that which would be incurred by a prudent person in the conduct of
competitive business. A cost is allocable if it is assignable or chargeable to one or
more cost objectives on the basis of relative benefits received or other equitable
relationship.
Contracting Officers (COs) are responsible for administering contracts. The FAR
specifies that the CO is responsible for ensuring performance of all necessary
actions for effective contracting and for safeguarding the interest of the United
States in its contractual relationships. In undertaking this effort, COs rely on the
contributions of numerous financial, legal, and technical experts. Due to the size
and complexity of Agency acquisitions, COs frequently appoint Contracting
Officer Representatives (CORs) to perform certain contract administration
activities.
Over the years, EPA has developed a wide range of unique titles for employees
who perform COR duties, such as project officer, work assignment manager,
delivery order project officer, task order project officer, and task monitor. Titles
and roles are based on the acquisition instrument managed - contract, work
assignment, task order, or delivery order. For purposes of this report, Project
Officer (PO) refers to all invoice approvers. We use the term COR to refer to
those who focus on the technical, day-to-day aspects of contract management on
behalf of the CO and who also work closely with POs when approving invoices.
1

-------
09-P-0242
According to EPA's Contracts Management Manual (CMM), the CO is
responsible for performing periodic reviews of invoices to ensure that the
contractor, PO, and CORs are properly fulfilling their roles, and that all issues
relevant to contract performance are being addressed. The CMM also requires the
CO to perform at least one detailed review of an invoice on each contract each
year.
Noteworthy Achievements
EPA's Office of Air Quality Planning and Standards has been responsive to the
audit team's comments regarding invoice reviews. During our field work, we
expressed our concern about instances where POs did not ensure CORs certified
the actual invoice, but rather allowed them to complete checklists based upon
monthly progress reports. Immediately, the Office of Air Quality Planning and
Standards Team Leader issued guidance to POs to ensure invoices and progress
report were in agreement, correct, and accurate. The guidance clarified the
process for certifying and approving contractor invoices for payment.
Additionally, two COs called a meeting with all their POs and highly
recommended they start using the checklist to complete their invoice reviews.
Scope and Methodology
We conducted this performance audit in accordance with generally accepted
government auditing standards issued by the Comptroller General of the United
States. These standards required 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.
We conducted the audit from September 2008 to August 2009. We also used
information collected as part of a separate review of the invoice process the OIG
conducted in 2007.
We obtained an understanding of the contract invoice review process through
analysis of the laws, regulations, and guidance, and an evaluation of internal
controls over the process. We reviewed the FAR, the EPA Acquisition
Regulation, and the CMM to understand regulations and directives governing
contract invoice review. We reviewed OMB Circular A-123 and EPA Order
1000.24 to understand management's responsibility for internal controls. Our
analysis of internal controls focused on control activities. We examined the
policies and procedures that management established to address the risks
associated with the invoicing process.
We visited the Office of Air and Radiation (OAR) and the Office of Acquisition
Management (OAM), both in Washington, DC, and in Research Triangle Park
2

-------
09-P-0242
(RTP), North Carolina. We also visited EPA Region 9 in San Francisco,
California, and RTP's Financial Management Center. We interviewed COs, POs,
CORs, managers in the payment office, and others to determine the process for
paying invoices. We reviewed contract clauses, invoices, monthly progress
reports and various backup documentation for invoices to determine whether costs
were supported and allowable.
We obtained a universe of 368 EPA time and material, cost-reimbursable and
level-of-effort contracts with a current contract value of almost $8.2 billion from
the July 2008 active contract listing. We focused on cost-reimbursable contracts,
as opposed to fixed-price contracts, as cost-reimbursable contracts pose a greater
risk to the government. Unlike fixed-price contracts, cost-reimbursable contracts
charge the government for expenses incurred and do not place full fiscal
responsibility and the resulting profit or loss with the contractor. The team
judgmentally selected a sample of 10 EPA contracts. We chose five contracts
each from EPA Region 9 and OAR to capture a nonstatistical sample from both a
national headquarters program office and a region. OAR and Region 9 offices
were selected based on the Fiscal Year 2007 OAM accomplishments reports that
showed that these offices accounted for a sizeable share of the contract dollars in
EPA. The two offices represented 19 percent of the universe of time and material,
cost-reimbursable, and level-of-effort contracts.
Once the contracts were selected, we selected two of the more recent invoices for
each contract. The dollar amount of the invoice was a consideration but not a
determining factor. We also selected invoices not related to the same work
assignment, task order, or line of accounting so that we would be speaking with
different POs and CORs. The 10 OAR invoices selected for review had a total
invoice amount of $196,285 (.002 percent of the universe). The 10 invoices
selected for Region 9 totaled $3,567,966, of which we reviewed $964,614 (.01
percent of the universe). Since it was a nonstatistical sample, the error rate in the
sample cannot be projected to the universe. See Appendix A for more details on
the sample of contracts and invoices we reviewed.
We reviewed the June 2004 OAM Intranet document titled Lessons Learned
From the FMR Program, to obtain an understanding of findings identified by
Financial Monitoring Reviews (FMRs) performed for 2004 and prior years. We
reviewed more recent FMRs for 2005 and subsequent years to determine if these
findings have continued.
We are not aware of any recent prior report recommendations specifically related
to this report's audit objective.

Chapter 2
Improvements Needed in Invoice Review Process
EPA should improve its invoice review procedures to ensure costs are allowable
and supported in accordance with the FAR. We found that:
•	invoice reviews were not documented,
•	PO reviews were based on incomplete information,
•	monthly progress reports did not always contain the information needed to
evaluate invoices, and
•	Agency staff did not perform required rate verifications and math checks.
Some responsible for reviews were unaware of the guidance and checklists in the
CMM, did not understand the level of documentation needed to review invoices,
or did not adhere to the guidance. Without adequate controls over the invoice
review process, the Agency becomes vulnerable to fraud, waste, abuse, and
mismanagement.
Guidance Requires Review of Invoices for Cost Reasonableness
According to CMM Section 11.2.5, it is the policy of the government to review
contract invoices thoroughly for cost reasonableness. The FAR states that no
presumption of reasonableness shall be attached to the incurrence of costs by a
contractor. The CMM invoice review checklists for POs and CORs illustrate the
important items they are to verify prior to invoice approval. The following are
some of the questions listed on the invoice review checklists.
•	Does the invoice period of performance cover the progress report period
of performance?
•	Are the labor categories and hours billed appropriate for the work
required?
•	Are indirect rates and costs billed at the authorized rates for that period of
performance?
•	Are other direct costs reasonable and within the contract approved dollar
ceiling?
•	Is the math accurate?
Invoice Reviews Not Documented
POs did not always document their review and approval of contractor invoices.
This occurred because POs did not understand the level of documentation needed
to sufficiently document invoice reviews. Appropriate documentation is necessary
4

-------
09-P-0242
to demonstrate that EPA is implementing its responsibility for invoice review.
Without documentation, EPA does not have assurance that the costs were
evaluated as to whether they are allowable and reasonable.
Although the CMM provides checklists for POs and CORs to use in reviewing
invoices, the use of the checklists is not mandatory. In the absence of checklists,
the CMM requires that the EPA staff reviewing the invoice provide
documentation to show that the appropriate review was performed.
We found 12 of 20 invoices (60 percent) were not supported by evidence of
review, either with a checklist or other documentation. For example:
•	An OAR contractor submitted an invoice for over $29,000 that was paid
without any evidence of review. The COR stated that he has the checklist,
but he does not use it every time. He explained that it would be helpful to
have some kind of training on what he should do and what should go in
the file. The COR stated that more guidance on what forms to use and
what records should be kept would be beneficial.
•	An invoice for over $413,000 submitted to Region 9 was approved and
paid without a checklist or any other evidence of tick marks or other
means of showing that it had been reviewed. The PO explained that she
spot-checks the cost among the invoice categories and did not document
her review.
Three factors contributed to the lack of documentation for invoice reviews. First,
EPA staff that review invoices believed that they were insufficiently trained in
reviewing invoices and documenting those reviews. However, EPA's required
training for CORs includes a chapter on the invoice review process, which
emphasizes the importance of the function and states that the COR must maintain
a file of all invoices, invoice review checklists, and all other documentation
associated with the invoice. The training materials include a copy of the invoice
review checklist from the CMM.
A second reason for the lack of documentation to support the invoice review is
that EPA does not require POs to use the checklist in the CMM. According to
OAM's Acting Director of Policy, Training and Oversight, the checklist is not
mandatory because it is provided as general guidance on how to perform invoice
reviews and as a tool to assist those who review invoices.
Finally, COs were not ensuring that invoice reviews were appropriately
documented. According to the CMM, the CO is responsible for performing
periodic reviews, as needed, to ensure that the POs and CORs are fulfilling their
roles properly in regard to invoice review. Several COs told us that they do not
check on how the POs and CORs are documenting their invoice reviews.
5

-------
09-P-0242
PO Reviews Based on Incomplete Information
For 6 of 20 invoices (30 percent), PO invoice approvals were based on incomplete
information. One PO approved two invoices based on invoice review checklists
that CORs completed; these checklists were based upon cost information from the
monthly progress report rather than the invoice. The PO did not provide the
CORs with copies of the invoices to perform their reviews. For the remaining
four invoices, the supporting documentation did not contain the detail needed to
evaluate the allowability and reasonableness of invoiced costs. Without complete
information, costs may be approved without EPA review to assess their
allowability and reasonableness.
The monthly progress report is an important tool in reviewing the invoice. The
report identifies the project's progress, difficulties encountered, and anticipated
future activity. However, without reviewing the invoice, the COR cannot
accurately assure that costs claimed, as identified on the invoice, are reasonable
and commensurate with work performed. For one of the invoices the PO approved
using COR-completed invoice review checklists, we found that the cost summary
information in the monthly progress report was not reliable. For example, the
hours for Professional Level III Engineer reported on the monthly progress report
were fewer than those reported on the invoice. The COR identified no exceptions
and recommended payment of the invoice based on the monthly progress report
alone. The PO approved the invoice for payment. The PO checklist noted,
"Direct charges appear to be reasonable, accurate and commensurate with the
level of effort performed during this time period." However, the PO's certification
was based on the COR's review of information in monthly progress report and not
the invoice.
The contract terms require invoices to contain a description of the cost charges or
detailed explanations for the cost categories when the costs exceeded set dollar
amounts. We identified four invoices with other direct costs totaling $39,065 that
POs approved for payment without a description of the costs as required in the
contracts. For two of the invoices, the costs exceeded the amount specified in the
contract for required detailed reporting. The PO approved the invoice in full
without the required detailed support for other direct costs. Without detailed
information for these costs, the PO cannot determine whether costs incurred and
paid by the government are allowable and reasonable for work performed.
Periods of Performance Differed from Monthly Progress Reports
Four of 20 invoices (20 percent) had periods of performance that differed from
the monthly progress report cost summaries. Each of the contracts required that
the period covered by the progress reports and invoices be the same. The POs
were aware of the different periods of performance, but not all had taken action to
correct the issue. With different periods of performance, it's difficult to match the
costs reported in the monthly progress report to costs invoiced.
6

-------
09-P-0242
EPA Acquisition Regulation Section 1552.232-70 paragraph e.l, which is cited in
contract terms and conditions, states, "when submitted on a monthly basis, the
period covered by invoices or requests for contractor financing payments shall be
the same as the period for monthly progress reports required under this contract."
According to the CMM, Chapter 11.2.5, Agency personnel are responsible for
reviewing the monthly progress report's consistency with invoices and for
verifying compliance of both invoices and monthly progress reports with contract
requirements. This is reflected in item number 2 of the PO and COR checklists,
which questions whether the invoice period of performance cover the progress
report period of performance. The CMM states that the CO is to conduct periodic
oversight to confirm compliance with invoices and monthly report clauses in the
contract.
Two of the four invoices with periods of performance that differed from the
progress report included:
•	For the Region 9 emergency response contract, the invoice period is based
on when relevant documentation is ready, and the progress report is issued
monthly. When we asked the PO how she knows that the invoiced billing
information is correct, the PO stated that it is correct "because it is done
out of the contractor's accounting system." However, just because the
information came from the contractor's accounting system does not ensure
that it is accurate or allowable. A financial monitoring review of this
contractor, performed in July 2008, determined that the contractor was not
complying with cost accounting standards. The PO stated she was not
aware of the results of the FMR.
•	For an air contract, one invoice was for a single day's worth of subcontract
charges, although the subcontractor invoice indicated the period of
performance was 3 days. The corresponding progress report covered 14
days' worth of work. The PO explained that this contractor uses different
periods of performance on its progress reports and invoices. For example,
another invoice that was not in our sample covered four separate monthly
progress reports. The PO said she depends on the CORs to tell her
whether the contractor did the work. If there are no problems, the PO will
approve the invoice.
The POs were taking varying levels of action to enforce the terms of contract.
One of the POs was working with the contractor to get the period of performance
to be the same in the monthly progress reports and invoices. Another PO's team
leader said he would take action to address the issue after we brought it to his
attention during the audit. The PO responsible for reviewing two of the sample
invoices did not consider the differences in period of performance as a problem
and did not take action. Invoices that are approved based upon supporting cost
documentation that covers a different period of performance presents a significant
7

-------
09-P-0242
control weakness in the invoice approval process. It also illustrates a lack of
enforcement of contract terms.
Rate and Mathematical Verification Were Not Performed
Agency staff did not perform their required rate verifications and math checks.
We found that RTP's Finance Center did not perform these activities, and POs
and CORs performed these activities for only 20 percent (4 of 20) of the invoices.
Without performing consistent rate verifications and math checks on invoices,
there is increased risk that overbillings could occur and not be detected prior to
invoice approval and payment.
Even though Agency guidance identifies the RTP Finance Center as having
primary responsibility for verifying rates and mathematical accuracy of invoices,
it is not performing this function. A payment section team leader explained that
the RTP Finance Center does not perform the verification because they believe
the task is more suitable to CORs.
Section 11.2.5.1 of the CMM delegates primary responsibility for rate verification
and mathematical accuracy on the invoice to RTP's Finance Center. In particular,
the Finance Center is responsible for confirming that the rates billed for indirect
costs, as well as for fixed or provisional rates for labor and equipment, are billed
consistently with the contract rates. The Finance Center is also required to
confirm that total current and cumulative costs are correctly summed, and that
rates are correctly multiplied to produce dollars billed for direct and indirect costs
(on a sample basis).
According to the CMM, the PO and COR are secondarily responsible for
verifying rates and mathematical accuracy of the invoice, but performed this
function on only 20 percent (4 of 20) of the invoices we reviewed. In one case
where the rates were not verified, we identified an overpayment to the contractor
of $368. This overpayment resulted from a fixed fee that was calculated using an
incorrect base. According to the terms of the contract, the rate for fixed fee was
to be applied to professional labor hours. However, the base on the invoice
calculation was for professional and nonprofessional labor hours. The PO
confirmed that the same problem occurred on additional invoices, which resulted
in a total overbilling of $560. This error would have been identified if either the
RTP Finance Center or COR had verified the mathematical accuracy of the fixed
fee calculation.
While the CMM designates RTP Finance Center as having primary responsibility
for rate and math verification, our observation is that the PO and COR are in a
better position to conduct this review. The PO and COR maintain files that
include the invoices and contract documents that would be needed to verify that
the contractor is billing the correct rates. The PO, when approving the invoice, is
expressing an opinion as to whether EPA should approve the invoice, which
8

-------
09-P-0242
would require verification of the rates and mathematical accuracy of the invoice.
OAM should reassign the responsibility for rate and math verifications to the POs
and CORs.
Although in our sample of 20 invoices the amount overpaid was minimal, it
illustrates the importance of checking math and verifying rates. Given that RTP
pays out more than $1 billion annually in contract payments, this dollar value
could escalate considerably if controls are not in place to prevent overpayment.
When the rate verification and math checks are not performed, the Agency is
susceptible to paying costs that are unallowable or unsupported. See Appendix B
for more details on invoice findings.
Recommendations
We recommend that the Assistant Administrator for the Office of Administration
and Resources Management:
2-1 Modify the CMM to require use of the checklist for invoice reviews the
CORs perform, and to ensure CORs receive invoices and supporting
documentation to assist their reviews.
2-2 Where the progress report and invoice did not cover the same time period,
require the contractors identified during this review to revise their progress
reports to match the time period of the invoice.
2-3 Re-evaluate the assignment of the responsibility for math and rate
verifications on contractor invoices and update the CMM accordingly.
2-4 Require that the COs, as part of the annual invoice review, perform
periodic reviews to make certain that the POs and CORs are:
a.	Implementing changes to the CMM made in response to the audit
report.
b.	Requiring contractors to submit invoices and progress reports with
matching periods of performance.
Agency Comments and OIG Evaluation
In responding to the draft report, EPA agreed to take action to address all of the
recommendations, and provided milestone dates for most of the
recommendations.
• Recommendation 2-1. OAM agreed that the CMM should be modified to
better define documentation needs at two levels: first, the supporting
documentation that needs to be supplied by the contractor to assist the COR in
invoice reviews; and second, the documentation that the COR needs to
9

-------
09-P-0242
prepare to prove that a sufficient invoice review has been performed. OAM
will encourage the use of the checklist, and will define the specific
documentation that is needed when the checklist is not used. An interim
policy notice will be issued by December 31, 2009. The CMM will also be
revised, but that may take an additional 6 months.
•	Recommendation 2-2. EPA contracting officers will send a letter to
contractors reminding them of the requirement that progress reports and
invoices cover the same time period. The letter will be issued by
December 31, 2009.
•	Recommendation 2-3. OAM agreed that math and rate verifications are
important and that they would discuss the issue of who is responsible for the
function with the Office of the Chief Financial Officer in greater depth by
November 30, 2009. Based on that discussion, OAM will provide an action
plan for addressing the recommendation. In responding to the final report,
EPA needs to provide an action plan, with milestone dates, to address
Recommendation 2-3.
•	Recommendation 2-4. OAM agreed that contracting officer reviews will be
used to verify compliance with the report recommendations. The quality
assessment plan policy in the EPA's acquisition handbook will be updated by
December 31, 2009.
The Agency's full response is provided in Appendix C.

Chapter 3
Financial Monitoring Reviews Have Identified
Repetitive Findings
OAM FMRs have identified repetitive findings related to contractor invoices.
The FMRs continue to find errors in invoices, some of which the PO and CORs
should have identified when reviewing the invoice. EPA did not develop a
corrective action plan to address invoice review internal control weaknesses
identified in FMR findings that were applicable across multiple contracts.
Instead, FMR findings are resolved solely on a case-by-case basis for a specific
contract. To maximize the usefulness of FMRs as an internal control tool, the
Agency should identify trends in FMR findings and recommendations. The
Agency can use this information to review and improve its invoice review process
and other areas. Doing so will help reduce the Agency's vulnerability to fraud,
waste, abuse, and mismanagement.
Guidance Requires Internal Control Monitoring
OMB Circular A-123, Management's Responsibility for Internal Control, states
that once internal control activities are put into place, continuous monitoring and
testing should help to identify poorly designed or ineffective controls. Findings in
audit and internal management reviews are one source of information about the
effectiveness of internal controls. In addition, a systematic process should be in
place for addressing deficiencies. EPA Order 1000.24, which implements OMB
Circular A-123, states that all methods of internal controls serve as the first line of
defense against fraud, waste, abuse, and mismanagement.
EPA's Cost Advisory personnel (i.e., the Financial Analysis Service Center at
Headquarters and for the Regions, or the Cost Analysis staffs at RTP and
Cincinnati, Ohio) perform FMRs on selected contracts. EPA schedules FMRs on
active contracts in excess of $5 million. The CO and Financial Administrative
Contracting Officer are responsible for resolving cost and financial issues raised
during these reviews. The FMRs target current contractor invoices to determine
whether there is adequate contractor data in the accounting records and systems to
support the contractor's billings, and to identify potential internal control issues
that might not otherwise be found until an audit is performed years later.

09-P-0242
Financial Monitoring Reviews Identify Repetitive Contractor Invoice
Findings
OAM FMRs have identified repetitive findings related to contractor invoices,
meaning similar issues were identified during FMR reviews at different
contractors. The OAM Intranet document titled Lessons Learned From the FMR
Program (June 2004) identified issues that were noted during FMR reviews,
including:
•	overtoiling of indirect costs
•	costs exceeding contract ceilings
•	inadequate support for contract billings
•	ineffective internal controls
•	inadequate policies and procedures
•	noncompliance with contractual and/or regulatory requirements
•	billing costs that are either unallowable, unallocable, or unreasonable
•	missing mandatory contract clauses
•	incorrect billing of fees
We found weaknesses and invoice errors during our review of 20 sample
contractor invoices similar to the findings identified in the FMRs. For example:
•	For 4 of 20 invoices, the monthly progress report dates differed from the
invoice dates, contrary to the requirements stipulated in the contract
terms.
•	For 4 of 20 invoices, there was inadequate support for other direct costs.
•	For 1 of 20 invoices, the fee was calculated incorrectly, resulting in an
overbilling of the fixed fee.
Because OAM's list of findings was several years old, we reviewed more recent
FMRs to determine if the issues continued. According to more recent FMRs we
obtained for 2005 and subsequent years, these FMR findings have continued.
Overall, there were a total of 51 findings identified in the more recent FMRs and
our invoice reviews combined. Of the 17 FMR findings from the OAM Intranet
document, the more recent FMRs and invoice reviews identified 12 of these
findings as continuing, with the most prevalent findings being (1) noncompliance
with contractual and/or regulatory requirements, and (2) inadequate support for
contract billings. Table 3-1, on page 13, illustrates the trends identified by the
FMR findings and this audit.
The FMRs continue to find errors in invoices that should have been identified
when EPA employees reviewed the invoices prior to approval for payment. For
example, overbillings of costs and incorrect fixed fee calculations should be
identified during invoice review. Improved internal controls over the invoice
review process, such as requiring the use of the invoice review checklist and
12

ensuring math checks and rate verifications are performed, would help ensure
such errors are detected prior to invoice approval for payment.

EPA Needs Action Plan in Response to FMR Trends
EPA has not used the FMR findings to identify changes that are needed in Agency
policy and procedures. Consequently, EPA did not develop a corrective action
plan to address invoice review internal control weaknesses identified in FMR
findings that were applicable across multiple contracts. Instead, FMR findings
are resolved on a case-by-case basis for the specific contract reviewed.
FMRs are useful tools that serve as a valuable internal control to identify trends
that should be addressed. EPA is not using the FMRs as a tool to identify where
improvements may be needed in EPA processes. In accordance with OMB
Circular A-123, EPA should take corrective actions in response to the trends
identified in the FMR findings. These changes may decrease the number of
13

-------
09-P-0242
repetitive findings and invoice errors identified by the FMRs for contractor
billings and reduce vulnerability of contract funds to fraud, waste, abuse, and
mismanagement.
Recommendations
We recommend that the Assistant Administrator for the Office of Administration
and Resources Management:
3-1 Analyze FMRs to identify findings that are recurring on multiple
contracts.
3-2 Develop a corrective action for addressing the common findings identified
in FMRs.
Agency Comments and OIG Evaluation
In responding to the draft report, EPA agreed with the recommendations and
provided milestone dates for completing corrective actions. EPA agreed to
conduct an analysis of the results of financial monitoring reviews by
November 30, 2009, and to develop a corrective action plan for addressing
common findings by December 31, 2009. The Agency's full response is provided
in Appendix C.

Re-evaluate the assignment of the responsibility for
math and rate verifications on contractor invoices
and update the CMM accordingly.
Require that the COs, as part of the annual invoice
review, make certain that the POs and CORs are:
a.	Implementing changes to the CMM made in
response to the audit report.
b.	Requiring contractors to submit invoices and
progress reports with matching periods of
performance.
Analyze FMRs to identify findings that are recurring

Agency Response to Draft Report
September 16, 2009
MEMORANDUM
SUBJECT: Response to Draft Audit Report: Contractor Invoice Internal Controls
Improvement, Project OA-FY08-0373
FROM: Craig E. Hooks
Assistant Administrator
TO:	Janet Kasper
Director, Contracts and Assistance Agreements
Office of the Inspector General
We appreciate the opportunity to comment on the report entitled "Contractor Invoice
Internal Controls Need Improvement," dated August 10, 2009. Our comments on the report and
recommendations are below:
Recommendation 2-1 - We recommend that the Assistant Administrator (AA) for the
Office of Administration and Resources Management (OARM) modify the Contract
Management Manual (CMM) to require the use of the checklist for invoice reviews the
contracting officer representatives (CORs) perform, and for CORs to receive invoices and
supporting documentation to assist their reviews.
Response - We agree that the CMM needs to be modified to better define documentation needs
at two levels: first, the supporting documentation that needs to be supplied by the contractor to
assist the COR in invoice reviews; and secondly, the documentation that the COR needs to
prepare to prove that a sufficient invoice review has been performed. We will encourage CORs
to use the checklist if it is applicable to their specific contract. However, that particular list is not
suitable for all contracts or all invoices. For cases where it does not apply, we will define the
specific documentation that the COR needs to prepare to properly document that an invoice
review has been performed. We propose to develop the new documentation definitions by
December 31, 2009, which we will promulgate via an Interim Policy Notice. (Formal CMM
revisions generally take about 6 months to complete.)
18

-------
09-P-0242
Recommendation 2-2 - We recommend that the AA for OARM require contractors, where
the progress report and invoice do not cover the same time period, to revise their progress
reports to match the time period of the invoice.
Response - We concur with this recommendation. EPA's contracting officers (COs) will notify
their contractors of this requirement, via a written letter, by December 31, 2009. In cases where
the contracts do not contain the requirement that progress report and invoice periods match, the
contracts will be modified.
Recommendation 2-3 - We recommend that the AA for OARM reassign the responsibility
for math and rate verification on contractor invoices to project officers (POs) and CORs,
and update the CMM accordingly.
Response - While we agree that math and rate verifications on invoices are an important internal
control that should be required, we believe that assigning responsibility for these reviews needs
to be further discussed. In some case, the PO or COR is the most logical candidate to perform
such checks; in other cases, OCFO-RTP may be in a better position to do so. We suggest that
you modify your recommendation and remove the identification of a specific party as being
responsible in all cases. We need to discuss this issue with OCFO in greater depth, and will do
so by November 30, 2009. Once this discussion has been held, we will respond to this
recommendation accordingly.
Recommendation 2-4 - We recommend that AA for OARM require that the COs perform
periodic reviews to make certain that POs and CORs are: (a) implementing changes to the
CMM made in response to the audit report; and (b) requiring contractors to submit
invoices and progress reports with matching periods of performance.
Response - We agree with these recommendations. These reviews will be carried out in each
COs annual review of invoices as required by their Division's or Region's Quality Assessment
Plan (QAP). The QAP policy will be modified accordingly in EPA's Acquisition Handbook, by
December 31, 2009.
Recommendation 3-1 - We recommend that the AA for OARM analyze financial
monitoring reviews to identify findings that are recurring on multiple contracts.
Response - We agree with this recommendation. The analysis will be completed by November
30, 2009.
Recommendation 3-2 - We recommend that the AA for OARM develop a corrective action
for addressing the common findings identified in financial monitoring reviews.
Response - We concur with this recommendation. The corrective action plan will be developed
by December 31, 2009.
