Current Site Status
The Interstate Lead Company (ILCO) site includes the area where ILCO operated a secondary lead smelter and lead battery recycling facility from 1970 until 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 National Priorities List (NPL) in 1986 because of contaminated ground water, 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 ground water and undertaking Five-Year Reviews, EPA, ADEM and the site’s PRPs continue to protect people and the environment from site contamination.
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.
Site investigations found contamination in ground water, sediment, soil and surface water that could potentially harm people in the area. Investigations at the seven satellite sites found contamination in soil, sediment and ground water contamination. Contaminants of concerns include lead, antimony, arsenic, cadmium, chromium and nickel.
Some ground water contamination remains below the main ILCO facility and the ILCO Parking Lot and Fleming’s Patio satellite sites. However, a water line connects people living or working in the area to the public water supply.
Investigation and Cleanup Responsibility / Oversight
ILCO Site Remediation Group, the site’s PRPs, lead site investigation and cleanup activities, with oversight provided by EPA and ADEM.
Site Cleanup Plan
Site investigations and cleanup activities have focused on three areas, which EPA refers to as operable units, or OUs. These areas include OU-1: soil, sediment and ground water contamination in the seven satellite sites near the main ILCO facility, except for ground water at the ILCO Parking Lot satellite site; OU-2: soil and ground water contamination at the Main ILCO facility and ground water contamination at the ILCO Parking Lot satellite site; and OU-3: contamination of surface water, sediment and fish in the unnamed tributary, Dry Creek and Little Cahaba River.
In 1991, EPA issued a cleanup plan (a Record of Decision, or ROD) for OU-1. The cleanup plan was amended in 1994 and 1996. The plan included the following activities:
- Digging up contaminated soil and sediment at the satellite sites.
- Transporting the dug-up soil and sediment to a centralized location at the main ILCO facility.
- Solidifying and stabilizing the contaminated soil and sediment.
- Removing contaminated debris from the satellite sites.
- Placing clean soil in the dug-up areas.
- Revegetating the dug-up areas.
- Placing institutional controls on the site property.
- Monitoring ground water.
In 1994, EPA issued a cleanup plan (a ROD) for OU-2. EPA amended the cleanup plan in 1996. The plan included the following activities:
- Digging up contaminated soil.
- Placing clean soil in the dug-up areas.
- Implementing a pump-and-treat system to address contaminated ground water.
- Placing institutional controls on the property to limit ground water and land use.
In 1995, EPA issued a cleanup plan (a ROD) for OU-3. The plan included the following activities:
- Using monitored natural attenuation to address contaminated sediment.
- Placing fishing advisory signs to warn of the presence of contaminated sediment and to inform people about the surface water, sediment and wildlife monitoring.
Data collected since the initial remedy was selected indicate that the soil, sediment, and groundwater remedies specified for the City of Leeds Landfill, Gulf/BP Service Station, and Dry Creek and unnamed tributary are no longer necessary. The remedies for the soil and groundwater at the City of Leeds Landfill and the Gulf/BP Service Station were changed to No Action. The soil and groundwater at these sites no longer pose a hazard, making additional cleanup action unnecessary.
Also, recent data supports amending the groundwater remedy for the ILCO Main Facility and Parking Lot from pump and treat to In Situ Precipitation. The amended remedial action for the OU-2 ILCO Main Facility and Parking Lot addresses the remaining contamination in the OU-2 groundwater. The remedial action for the soil, which included excavation and off-site disposal at an approved facility, was not changed. The major components of the selected remedy for the amended remedial action include:
- Injection of reagent into the soil in the former battery breaker area at the Main Facility to increase the pH and thus reduce the solubility of metals in the subsurface soil. The subsurface soil contains a diffuse source of acid which lowers the pH, leaches metals from the subsurface soil, and provides a source of metals contamination to groundwater via rainwater percolation. This results in levels of manganese, nickel, beryllium, and cadmium that exceed remedial goals in the onsite groundwater. Levels for these contaminants meet drinking water standards off-site.
- Monitoring of the contaminants of concern (COCs) in the groundwater to verify that the groundwater pH is neutralized and that groundwater meets remedial goals;
- Institutional controls until remedial goals are met. This includes, but is not limited to, restricting groundwater for potable or drinking water uses and maintenance of access controls and warning signs around the ILCO Main Facility.
For OU-3, Dry Creek and the unnamed tributary, the amended remedy for the sediment and surface water is No Action. No additional remedial action is necessary since sampling shows that lead levels in all media no longer pose an unacceptable risk to human health and the environment. As a result, the fish advisory and surface water, sediment, and biota monitoring are no longer necessary.EPA issued the final amended ROD to the OU-1, OU-2, and OU-3 RODs in September 2012 to reflect these changes.
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 approximately 5,000 cubic yards of waste material and soil. In 1992, EPA conducted cleanup activities at the main ILCO facility. EPA removed and transported over 5,000 tons of contaminated material to a permitted hazardous waste landfill and collected and treated 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 2004 and 2005, 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 In Situ Precipitation remedy for the OU-2 groundwater. The PRP Group will provide the design documents for EPA and ADEM review and approval and proceed with the implementing the ground water remedy. The PRP Group plans to implement the OU-2 groundwater remedy activities in summer 2012.
The site’s second Five-Year Review, completed in 2011, 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.
EPA negotiated legal agreements with the site PRPs to fund site cleanup, monitoring and oversight activities.
EPA has 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 has 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 and information meetings.
For the 2012 amended Record of Decision, EPA issued an Amended Proposed Cleanup Plan to the public as part of the process to modify the remedies. ADEM reviewed and concurred with the remedy described in the Amended Proposed Plan for the modified remedial actions prior to the plan being released for public comment. EPA published a notice of availability for the final Amended Proposed Plan in the Leeds Herald newspaper and provided the public with an opportunity to provide written and oral comments to EPA from June 18 to July 18, 2012. No comments were received from the public.
Prior to beginning the OU-2 groundwater remedial action, EPA will notify the surrounding community of the activities.
EPA is working to implement the OU-2 remedy to address ground water contamination. Monitoring of ground water will continue until remedial goals are reached.
EPA completed the last Five-Year Review in 2011 and plans to complete the next Five-Year Review in 2016.
