Entering Institutional Controls
into One-Call Systems

The Environmental Protection Agency's Office of Solid Waste and
Emergency Response initiated a series of innovative pilot projects to test
ideas and strategies for improved environmental and public health results.
This series of fact sheets highlights the innovative approaches, results, and
environmental and economic benefits from the pilot projects that may be
replicated across various sectors, industries, communities, and regions.

PROJECT description/innovation

EPA awarded an Innovation grant to the Office of Superfund
Remediation and Technology Innovation (OSRTI) to test the
viability of including sites with institutional controls (ICs) into
state one-call systems. States established one-call systems
in the 1960s to help excavators identify the location of buried
utility lines. States recognized the need for these systems to
prevent damage to underground facilities and to protect the
public and environment from uncontrolled excavation. The
pilot set out to determine whether the one-call infrastructure
might work to notify these same excavators of underground
environmental considerations protected by ICs. This was the
first time such an idea had been implemented. Building on
existing state and federal authorities, the pilot focused on the
areas where the potential merits of adding IC elements into
one-call systems were widely agreed upon.

BACKGROUND

At many environmental cleanups under federal, state and local
agency jurisdiction, residual contamination and engineering
controls remain after cleanup has been completed. In such
situations, the lead environmental agency typically requires
legal or administrative tools to be implemented on a site.

Known as institutional controls, these tools limit usage so that
contaminated areas or cleanup components already in place
are not disturbed. While these ICs perform a vital function, the
protections they provide may be disturbed during major land
use changes or transactions, but not during more routine site
activities. Therefore, future construction activities, including
site excavation, well construction and grading pose a risk of
unknowingly disturbing the contaminated area and jeopardizing
the efficacy of ICs. Although ICs are important components
of the cleanup plan, they often are implemented, monitored
and enforced by an entity other than the one completing the
cleanup. This separation of responsibility for the implementation,
monitoring and enforcement of institutional controls requires
active management to ensure awareness of the controls.

• Identified and screened a total of 1,124 potentially
conflicting land use activities within or near areas of
concern in California from February to June 2004.

• Identified and prevented 21 land use activities
that could have directly conflicted with areas of
contamination, remedy components or ICs. These
included proposed excavations reported through the
California one-call system as well as building permit,
real estate, water well and construction activities
identified through a combination of local agencies and
public sources.

PROJECT SUMMARY

Phase I of the pilot was initiated in 2002 when OSRTI
partnered with EPA Regions 3 and 5, and the States of
Wisconsin and Pennsylvania, to test the viability of including
sites with institutional controls (ICs) into state one-call
systems. The pilot conducted focused research on how sites
were entered into the state one-call systems of Wisconsin
and Pennsylvania. This information was then used to test
the entry of sites with ICs into one-call systems; test one-
call system variations; and test various methods to receive,
manage and respond to location requests.

EPA worked with Wisconsin and Pennsylvania to further
evaluate whether the one-call infrastructure could also work
to notify the state and EPA of planned excavations at sites
where ICs exist, and notify site excavators of the presence of
environmental contamination or underground cleanup remedy
components, prior to excavation activities.

In Phase II of the pilot, EPA worked with Terradex, Inc
(Terradex) in 2003 to enhance the lessons learned from
Phase I by combining the one-call system with other types of
pre-emptive notifications in California. An informal selection


-------
team consisting of EPA, Terradex, and the California State Water
Resources Control Board selected 18 sites to be evaluated
under the pilot. After the pilot sites were chosen, members of
the selection team organized stakeholder meetings with state
representatives, contractors, responsible parties (RPs), and
regulatory agencies to provide an overview of the Terradex
monitoring service and of the pilot program as a whole.

RESULTS

This project indicated that the one-call system can be utilized
as an effective means for IC notification. The pilot developed
information that will help prevent excavation, grading, well drilling
and other future site activities from compromising contaminated
soil, ground water or cleanup-related components—reducing
risks to the health and safety of site excavators, government
personnel and the public. Some of the more specific results of
the pilot included:

•	Provided specific examples of where one-call systems
successfully informed excavators of ground water
contamination issues.

•	Detected 21 potentially damaging activities in California
before they occurred, demonstrating the ability of a
monitoring service—participating as a member of the local
one-call system and obtaining permitting and other land
transaction information—to effectively monitor use activities
in restricted areas. The pilot also demonstrated that the
monitoring and response system can identify—and in many
cases prevent—actions that could interfere with ICs and
other remedies where contamination remains onsite.

•	Confirmed that one-call systems, the real-estate Multiple
Listing Service (MLS), county permits, and other public
sources of information were very useful in providing
information about site conditions to multiple parties prior to
the initiation of activities at a site.

In general, states with properties that have contamination onsite,
underground remedy components and/or ICs could benefit
from the approach used in this pilot project. Additional work
is necessary to replicate this approach nationwide. The pilot
partners have continued to work with the one-call industry and
states to develop best management practices and refine costs
and benefits.

2010 UPDATE

The pilot raised awareness of ICs and one call systems and
initiated a national conversation about these systems. For
example, Mississippi drew upon the lessons learned from
the pilot to develop a conceptual model for incorporating
institutional and engineering controls into the Mississippi
One-Call System. Several states such as California have
implemented one-call systems that include ICs. In February
2006, EPA developed a summary report on Phase II of the
pilot that can be found at: www.terradex.com/PublicPages/
