Region 5 Oversight of PRP-lead Remedial Design and Remedial Action
El SGF8-05-0035-8100208
August 17,1998
EXECUTIVE SUMMARY
INTRODUCTION
The Office of Inspector General (OIG) performed an audit of Region 5's management of potential responsible
party (PRP) lead remedial design and remedial action activities (remedial construction projects). We selected
this audit because PRPs perform the majority of Superfund cleanup activities and many of these are in the
remedial design and action phases. When the PRPs conduct the cleanup, the Environmental Protection Agency's
(EPA) role is to ensure that the PRP complies with all applicable laws, regulations, and requirements; and meets
all performance standards in the settlement agreement or order.
OBJECTIVES
The objectives of the audit were to determine, for PRP lead sites in the remedial design and action phases:
•	if Region 5 was effectively overseeing responsible parties and
•	the impact of the Superfund Administrative Reform on reducing oversight for cooperative responsible
parties.
RESULTS IN BRIEF
Region 5 provided effective oversight of PRPs. Regional project managers (RPMs) ensured that remedies were
being completed in accordance with the record of decision and that time schedules in the settlement agreement
or order were met. The RPMs accomplished effective oversight by establishing good working relationships with
the PRPs. This included open communication and working through issues as they occurred, before they turned
into major problems. More frequent use of independent quality assurance teams is one area where Region 5
could improve its oversight of PRPs.
The impact of the reduced oversight administrative reform in Region 5 was difficult to measure due to (a) the
inherent nature of the oversight process and (b) cost savings from reductions in oversight not being computed.
As a result, for fiscal years (FY) 1996 and 1997, the Agency could not determine the extent of the impact of this
reform and whether it was successful in Region 5. For FY 1998, the Agency has developed an evaluation form
that, when completed, may provide management with the information it needs to evaluate the impact of the
reform.

RECOMMENDATIONS
We recommend that the Acting Regional Administrator, Region 5, take the following actions.
•	Require the Superfund division to (1) use independent quality assurance teams for PRP lead remedial
construction projects, and (2) verify that independent quality assurance teams are being used
appropriately. When independent quality assurance teams are not used, the reasons for not using them
should be documented.
•	Ensure the Superfund division yearly completes the evaluation form for sites in the reduced oversight
administrative reform in order to compute costs savings.
AGENCY COMMENTS AND ACTIONS
Region 5 agreed to take action to address the findings and recommendations in the report.
•	Starting October 1, 1998, the RPM will evaluate the appropriateness of using an independent
construction quality assurance team for each workplan received for PRP remedial construction projects
performed pursuant to an EPA settlement or order. In any case where such a team will not be used, the
RPM will document the reasons in a memorandum.
•	The evaluation form for sites in the reduced oversight reform will be completed and submitted to EPA
Headquarters by October 10, 1998.
OIG EVALUATION
Region 5's actions, when completed, will address the findings and recommendations in the report.
