One-Call Pilots
Utility companies prevent damage to their underground facilities by utilizing One-Call systems to inform excavators about the location of underground utility lines. EPA is evaluating the feasibility of expanding the protection provided by such One-Call systems by entering cleanup sites, which contain residual contamination or underground cleanup-related mechanisms, into One-Call systems.
Under EPA's One-Call pilot strategy, EPA hopes to prevent excavation, grading, well drilling, and other future site activities from contacting contaminated soil, groundwater, or cleanup-related mechanisms. In turn, EPA hopes to reduce the risks of harm to the health and safety of site excavators, other site personnel, and the public. Without the entry of such sites into One-Call systems, excavators might unknowingly contact or otherwise disturb residually contaminated media or underground environmental cleanup mechanisms.
Demonstration Areas
EPA - Pennsylvania Department of Environmental Protection One-Call Pilot - This pilot involves the efforts of EPA, the Pennsylvania Department of Environmental Protection (PA DEP), and the Pennsylvania One-Call system, Pennsylvania One-Call System, Inc. (POCS). This pilot is exploring the feasibility and impact of regulatory or legislative changes that would expand the Pennsylvania One-Call legislation to expressly cover subsurface contamination, or otherwise require residually contaminated sites to join POCS. Such amendments would mark the first step, nationwide, to formally require owners/operators of residually contaminated sites to join the One-Call system.
EPA - Wisconsin Department of Natural Resources One-Call Pilot - This pilot involves the efforts of the Wisconsin Department of Natural Resources (WDNR), EPA Region 5, EPA Headquarters, and the Wisconsin One-Call service, Diggers Hotline. Together, these organizations are coordinating to place IC information associated with Superfund, Resource Conservation and Recovery Act (RCRA), Underground Storage Tank (UST), and State Voluntary Cleanup sites within the Diggers Hotline system. Through the efforts of this pilot, it is envisioned that in addition to learning the location of underground utility lines, excavators will learn whether subsurface environmental contamination exists.
EPA - New York Department of Environmental Conservation One-Call Pilot - This pilot involves EPA, the New York State Department of Environmental Conservation (NYSDEC), and the New York One-Call system, Dig Safely New York, Inc. Together, these organizations are beginning efforts to prove the concept of environmental site entry into the One-Call system.
