Current Site Status
The Bypass 601 Ground Water Contamination site includes the area where Martin Scrap Recycling (MSR) operated a battery salvage and scrap metal recycling facility from 1966 to 1986. The site also includes 10 additional areas where MSR disposed of battery material. EPA placed the site on the National Priorities List (NPL) in 1986 because of contaminated ground water, sediment, soil and debris resulting from waste disposal operations. EPA, the South Carolina Department of Health and Environmental Control (SCDHEC) and the site’s potentially responsible parties (PRPs) have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. Site contamination does not currently threaten people living and working near the site. By monitoring ground water, placing institutional controls on the site property and undertaking Five-Year Reviews, EPA, SCDHEC and the site’s PRPs continue to protect people and the environment from site contamination.
The 13-acre site is located on the western edge of Concord in south-central North Carolina. The site includes the MSR battery salvage and scrap metal recycling facility and the following 10 additional areas where MSF disposed of battery material and debris:
- Source Area 1 (located next to an unnamed stream, west of Bypass 601).
- Source Area 2 (located south of Montford Avenue and west of Bypass 601; the previous site of the MSR facility).
- Source Area 3 (located at 72 Sumner Avenue).
- Source Area 4 (commercial property north of and adjacent to the MSR facility occupied by an abandoned flea market).
- Source Area 5 (located at a private landfill along the eastern boundary of the MSR facility).
- Source Area 6 (located behind a tire store on the corner of McGill and Bypass 601).
- Source Area 7 (the radio tower site located approximately one quarter-mile north of the MSR facility).
- Source Area 8 (the floodplain area south of an unnamed stream).
- Source Area 9 (a small area south of Montford Avenue next to the unnamed stream, approximately 200 feet west of Bypass 601).
- Source Area 10 (adjacent to a second unnamed stream in a heavily wooded, hilly area next to Barnhardt Avenue, Groff Street and Montford Avenue).
U.S. Highway 29/Route 601 borders the site to the west, a former flea market and landfill border the site to the north, Irish Buffalo Creek borders the site to the east and an unnamed tributary of Irish Buffalo Creek borders the site to the south. Site surroundings include light industrial and commercial land uses, with several residential areas located south and west of the site.
The MSR facility operated from 1966 to 1986. Operations included recovering scrap metal, mostly lead, from scrap vehicle batteries. MSR collected and disposed of waste in a surface impoundment on site. In 1982, MSR began storing waste in stainless steel holding tanks.
A private parking facility is now located on part of the site.
Site investigations found contamination in ground water, sediment and soil that could potentially harm people in the area. Contamination resulted from waste handling and disposal practices. Contaminants of concern identified include metals, including lead, and volatile organic compounds (VOCs).
Investigation and Cleanup Responsibility / Oversight
EPA led site investigation activities. The site’s PRPs lead site cleanup activities, with oversight provided by EPA and SCDHEC.
Site Cleanup Plan
Site investigations and cleanup activities have focused on two areas, which EPA refers to as operable units, or OUs. These areas include OU-1: soil contamination at the MSR facility; and OU-2: the 10 additional source areas and the site’s ground water contamination.
In 1990, EPA issued an interim cleanup plan (a Record of Decision, or ROD) for OU-1. The plan included the following activities:
- Demolishing four on-site structures.
- Disposing of building debris in an off-site landfill.
- Recycling metal materials.
- Crushing and consolidating building concrete and stone with contaminated surface soils.
In 1993, EPA issued a cleanup plan (a ROD) for OU-2 as well as a ROD Amendment for the final cleanup plan identified in the 1990 ROD for OU-1. The plans included the following activities:
- Demolishing and disposing of the abandoned flea market and remaining MSR facility buildings at an off-site municipal landfill.
- Digging up contaminated soil.
- Solidifying and stabilizing contaminated soil.
- Placing clean soil in the dug-up areas and grading and revegetating the areas.
- Using a pump-and-treat system to address ground water contamination.
- Discharging treated ground water to a local water treatment plant.
In 1997, EPA issued a ROD Amendment that modified the 1993 ROD for OU-2. The amended plan included the following activities:
- Using monitored natural attenuation instead of the pumping and treat system to address ground water contamination.
- Treating and placing a cap over dug-up soil from the MSR facility, Source Area 4 and Source Area 5.
EPA did not implement the cleanup plan in the 1990 ROD for OU-1. In 1992, EPA conducted a short-term cleanup to remove contaminated soil on four of the site’s source areas. In 1996, site PRPs conducted a second cleanup to remove remaining contaminated soils on the four areas.
The PRPs conducted cleanup activities for OU-2 in two phases, beginning in September 1996. During Phase 1, PRPs removed approximately 16,750 cubic yards of soil and debris and transported the materials to the MSR facility. The PRPs completed Phase 1 cleanup activities in November 1996.
Phase II began in 1998 and included the solidification/stabilization of approximately 10,420 cubic yards of materials, demolition of old buildings and the construction of a cap over the MSR facility, Source Area 4 and Source Area 5. Site PRPs placed a fence around the edge of the cap. The PRPs completed Phase 1 cleanup activities in 1999.
EPA placed institutional controls on the site property to make sure the cleanup continues to protect human health and the environment.
The site’s second Five-Year Review, completed in 2007, found that the cleanup remains protective of human health and the environment. However, institutional controls need implementing on the fourth property parcel at the site.
EPA negotiated legal agreements with the site’s PRPS to clean up the site. The PRPs continue to fund site cleanup, monitoring and oversight activities.
EPA worked with the community and its state partner to develop a long-term cleanup plan for the site, reflecting the Agency’s commitment to safe, healthy communities and environmental protection. Community engagement and public outreach are core components of EPA program activities.
EPA conducted a range of community involvement activities to solicit community input and to make sure the public remains informed about site activities throughout the cleanup process. Outreach efforts have included public notices, interviews and public meetings.
Ground water contamination remains under one area of the site. PRPs continue to use monitored natural attenuation to address ground water contamination.
EPA plans to place institutional controls on the site’s fourth land parcel.
EPA completed the last Five-Year Review in 2012 and plans to complete the next Five-Year Review in 2017.
EPA keeps additional site documents and information in a site information repository at the location below. EPA also posts site documents, when available, on EPA’s CERCLIS Site Profile page. For documents not available on the website, please contact the Region 4 Freedom of Information Office.
