Available to RPMs

Optimization of 20 Fund-lead P&T systems via Remediation System Evaluations (RSEs) has
identified a number of opportunities for system enhancement, and in many cases, reductions
in annual operation and maintenance costs. Implementing these recommendations, however,
will require expertise in a variety fields, and the Remedial Project Managers (RPMs) of these
systems may need technical assistance. This pamphlet introduces the technical assistance
resources available to RPMs both within and beyond their Region.

The graphic below presents a summary of the resources available to RPMs as they implement
RSE recommendations.

Support within a Region

"In-House" Support

Internal or "in house" support structures for RPMs vary by Region. Some Regions,
including Region 2, Region 3, and Region 10, have hydrogeologists assigned to each
site. Other Regions, such as Region 6, rely on third-party contractors or outside
avenues for technical support. Regardless of the technical support structure, it is
recommended that RPMs exchange information with each other because each RPM
has gained expertise based on previous experience.

Third-Party Contractors

Although site contractors are capable of handling most of the technical issues that arise
at a site, there may be situations where technical assistance from another source is
more appropriate. For example, a site contractor may have expertise on O&M of a
treatment facility, but may not have the expertise necessary for groundwater modeling.
Also, an RPM may need to make a decision based on a technical evaluation, and an
outside party may be needed to provide unbiased support. In such cases, RPMs can
seek support from other contractors:

Response Action Contractors (RACs)

U.S. Army Corps of Engineers (USACE) and associated subcontractors
United States Geological Survey (USGS) (especially for hydrogeological
support)

Support Beyond the Regions

Engineering Forum, Groundwater Forum, and Superfund Technical Liaisons

The Engineering and Groundwater Forums are two independent groups of scientists,
engineers, and support staff that support the Superfund and RCRA programs in each
of the ten EPA Regional Offices. Additional participants come from the EPA
Laboratories, EPA Headquarters, and the states. The groups were organized to
exchange up-to-date information related to engineering remediation and
hydrogeological issues at Superfund and RCRA sites. A Superfund Technical Liaison
(STL) in each Region is assigned as a link between their Region and the EPA Office of
Research and Development. Together these STLs and the Forums promote
communication between the Regions and the Laboratories and have three primary
purposes:

to bring the current state-of-the-science to each regional office as it is
developed through the research efforts at the labs;

to focus laboratory resources on research areas important to the ground-water
scientists working in each EPA Region; and

to maintain consistency in the interpretation of guidance and application of
policy throughout the country.

The members in each of the two Forums are listed by Region or EPA office online at
http://www.epa.gov/tio/tsp.

ORD Technical Support Centers and Contacts

There are eight technical support centers throughout the nation capable of offering technical
assistance through the Technical Support Program. Mechanisms for contacting these
centers vary by Region. In some Regions, such as Region 6, RPMs contact the centers
directly. In other Regions, such as Region 10, the common avenue of communication is
through a Engineering or Groundwater Forum member. Those Forum members have
contacts at the support centers and can facilitate interactions. The cost of the technical
assistance may not exceed $25,000, and formal requests for assistance must be made in
writing. Summaries of the eight centers are provided below and more information can be
found at http://www.epa.gov/tio/tsp.
