The Interstate Lead Company (ILCO) site is located in Leeds, Alabama. It includes the area where ILCO operated a secondary lead smelter and lead battery recycling facility from 1970 to 1992. The site also includes seven satellite sites located in and around Leeds, Alabama, where the company disposed of contaminated wastes from its main facility. EPA placed the site on the Superfund program’s National Priorities List (NPL) in 1986 because of contaminated groundwater, sediment, soil and surface water resulting from facility operations.
EPA, the Alabama Department of Environmental Management (ADEM) and the ILCO Site Remediation Group, 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. A water line connects residents and businesses to the public water supply. By conducting cleanup activities, placing institutional controls on site properties, monitoring groundwater and undertaking Five-Year Reviews, EPA, ADEM and the site’s PRPs continue to protect people and the environment from site contamination.
What Is Being Done to Clean Up the Site?
The ILCO Site Remediation Group, the site’s PRPs, lead site investigation and cleanup activities, with oversight provided by EPA and ADEM.
In the early 1980s, EPA and ADEM conducted investigations and found the main ILCO facility in violation of hazardous waste storage, disposal and discharge standards. In 1984, EPA conducted short-term cleanup activities at the Acmar Church of God (now the New Life Fellowship) satellite site. EPA removed 5,000 cubic yards of waste material and soil. In 1992, EPA conducted cleanup activities at the main ILCO facility, removing and transporting over 5,000 tons of contaminated material to a permitted hazardous waste landfill and collecting and treating acid stored in several on-site impoundments.
Between 2000 and 2001, PRPs dug up, treated and disposed of 220,243 tons of soil and debris off site. In addition, in 2004 and 2005 the PRPs removed additional contaminated soil. PRPs have completed nearly all cleanup activities. EPA placed institutional controls on the main ILCO facility and the ILCO Parking Lot and Fleming’s Patio satellite sites to restrict land use and the placement of wells on the property.
EPA has directed the PRP Group to proceed with the design of the remedy for OU-2 groundwater. The PRP Group implemented OU-2 groundwater cleanup activities in the summer of 2013.
The site’s third Five-Year Review in 2016 found that the cleanup for OU-1 remains protective of human health and the environment and that the cleanup for OU-2 and OU-3 will be protective of human health and the environment upon completion of cleanup activities. EPA plans to complete the next Five-Year Review in 2021. In addition, EPA is working to implement the OU-2 remedy to address groundwater contamination.
What Is the Current Site Status?
For cleanup, EPA divided the site into three areas, referred to as operable units, or OUs. OU-1 addresses soil, sediment and groundwater contamination in the seven satellite sites near the main ILCO facility (ILCO Parking Lot, the Gulf/BP Service Station, J&L Fabricators, Fleming’s Patio, the Connell Property, the New Life Fellowship and the City of Leeds Municipal Landfill). OU-2 addresses soil and groundwater contamination at the Main ILCO facility and groundwater contamination at the ILCO Parking Lot satellite site. OU-3 addresses contamination of surface water, sediment and fish in the unnamed tributary, Dry Creek and Little Cahaba River.
In 1991, EPA issued a cleanup plan for OU-1 and updated it in 1994 and 1996. In 1994, EPA issued a cleanup plan for OU-2 and updated it in 1996. In 1995, EPA issued a cleanup plan for OU-3.
EPA issued final revised cleanup plans for OU-1, OU-2 and OU-3 in September 2012 based on the results of ongoing data collection. OU-1 and OU-3 data indicate that the cleanup plans for soil, sediment and groundwater for the City of Leeds Landfill, Gulf/BP Service Station and Dry Creek and unnamed tributary are no longer necessary. In 2012, EPA revised the cleanup plan to select “no action” for these areas. In addition, in 2012, EPA revised the cleanup plan for OU-2, changing the remedy for groundwater at the ILCO Main Facility and Parking Lot from pumping and treatment to in-place precipitation with groundwater monitoring; and using institutional controls to restrict groundwater use and limit site access.
EPA is working on the most appropriate way to address ground water contamination. Monitoring of ground water is ongoing. EPA completed the last Five-Year Review in 2016 and plans to complete the next Five-Year Review in 2021.
EPA’s Involvement at the Site
The 11.5-acre site is located in Leeds, Alabama, approximately 15 miles east of Birmingham. The site includes the main ILCO facility and seven satellite sites in and around Leeds. The main ILCO facility is located at 8551 Borden Avenue (formerly 1247 Borden Avenue) in southeast Leeds. The seven satellite sites include: -The ILCO Parking Lot, located across the street from the main ILCO facility. -The Gulf/BP Service Station, located in the center of Leeds on U.S. Highway 78. -J&L Fabricators, located east of Leeds on U.S. Highway 78. -Fleming’s Patio, located west of Leeds on Alaska Avenue. -The Connell Property, located east of Leeds in St. Clair County. -The Acmar Church of God (now the New Life Fellowship), located on Acmar Road in Moody, Alabama. -The City of Leeds Municipal Landfill, located off Dunavant Road. Borden Avenue and the ILCO Parking Lot border the main ILCO site to the north, an abandoned foundry and a wooded area border the area to the south, an unnamed tributary of Dry Creek borders the area to the west, and a commercial business borders the area to the east. Site surroundings include industrial and residential land uses. The main ILCO facility operated as a secondary lead smelter and lead battery recycling facility from 1970 to 1992. From 1970 to 1984, ILCO disposed of contaminated materials and wastewater treatment sludge at the seven satellite sites. In 1986, EPA listed the site on the NPL. ILCO declared bankruptcy in 1992. The vacant main ILCO facility is fenced and gated. ILCO and Interstate Trucking Company, Inc., an affiliated company, own the main ILCO facility and the ILCO Parking Lot satellite site across the street. Residential and other land uses remain in place at several satellite sites.
Sampling and Monitoring
As indicated in the 2013 RD/RA Work Plan, the post remediation long-term groundwater monitoring program was designed to monitor the continued decrease of metals, following the completion of the remedial action, which involved the injection of approximately 72 tons of sodium bicarbonate into the unsaturated soil in the former battery breaker area at the ILCO main facility. The RD/RA Workplan contains recommendations for determining frequency, wells and analytes to be included in the future groundwater monitoring events.
EPA negotiated legal agreements with the site PRPs to fund site cleanup, monitoring and oversight activities.
