The Wrigley Charcoal Plant Site includes seven distinct areas affected by various industrial activities. The U.S. Environmental Protection Agency (EPA) placed the Site on the National Priorities List (NPL) in 1989 because of contaminated debris, ground water and soil resulting from facility operations dating back to the 1880's.

In 1995, Industrial Plastics Recycling started operating a small-scale recycling facility on the southern portion of the Site. Industrial Plastics Recycling conducted metals and plastics recycling, storage of waste products and other related activities on the southern portion of the Wrigley Charcoal Plant NPL Site. Industrial Plastics Recycling utilized approximately 15 acres of the NPL Site and consisted of a large warehouse, a large processing building and approximately five acres of outside/uncovered storage of processed and unprocessed acrylic, poly-carbonate, ABS, polyethylene, polypropylene, styrene, PVC and PETG plastics in totes and piles. The Site is surrounded by residential communities and directly adjacent to the North Fork of Mill Creek.

On December 18, 2013, the Industrial Plastics Recycling facility caught fire. Approximately five acres of plastics and surrounding buildings were involved and on fire. A large smoke plume ensued that extended for miles downwind. Numerous homes and business were impacted by the smoke plume. State and local officials implemented a 1½-mile evacuation zone in all directions.  The EPA responded under emergency authority and assisted with extinguishing the fire. The fire resulted in significant damage to the buildings and structures at the Site, and Industrial Plastics Recycling ceased operating at the Site.  For additional information regarding the Industrial Plastics incident, please visit the following website: http://epaosc.org/industrialplasticscofire
 

The fire, time, and weather events have impacted the roofing tiles on the old buildings.  The majority of the tiles have fallen onto the ground. Testing by TDEC and EPA verified the tiles contain asbestos.  A time critical removal action will be conducted by EPA to address the asbestos tiles and any soil areas impacted by the asbestos.

1.1.2.1 Location

The Site address is 8526 Plant Road, Lyles, Hickman County, Tennessee. The Site is located northwest of Highway 100, about 45 miles southwest of Nashville. The Site is surrounded by residential communities and directly adjacent to the North Fork of Mill Creek. 

1.1.2.2 Description of Threat

On April 20, 2015, the EPA and Tetra Tech collected 66 bulk samples from suspect asbestos-containing materials associated with the site buildings and site building debris. Analysis of the bulk samples indicated 10 of the 66 samples contained asbestos concentrations greater than one percent. The concentration of asbestos in the roof material ranged from 10 to 60 percent. On April 21, 2015, the EPA and Tetra Tech collected composite soil samples from 25 delineated surface soil areas outside of the building and structures. These samples were collected to determine if surface soils located further away from the building exterior walls contained asbestos. Five of the 25 samples contained concentrations of asbestos ranging from 0.30 to 0.60.

The disease and pathology associated with the inhalation of asbestos fibers is well documented in the medical literature. Congress has found that “medical science has established that no minimal exposure to asbestos fibers which is considered safe to exposed persons.” (20 U.S.C. § 3601(a)(3). If inhaled, asbestos fibers can increase the risk of developing lung cancer, mesothelioma, pleural fibrosis and asbestosis.

In addition to potential exposure to nearby residents, the EPA SRSEB plans to undertake extensive sampling and remedial action as part of the NPL process; therefore, human exposure is likely under current Site conditions. Site conditions are consistent with criteria outlined in the September 2008 EPA OSWER Directive 9200.0-68 “Framework for Investigating Asbestos-Contaminated Superfund Sites”, which supports a removal action when human exposure is likely. An action is warranted to prevent exposure to workers who will be operating at or near the area of contamination, future tenants and nearby residents.

1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results

In December 2013, the TDEC Division of Air Pollution Control collected samples from the Site. Sample results verified that asbestos-containing material (chrysotile) was present at the Site.

On April 20, 2015, the EPA and Tetra Tech collected 66 bulk samples from suspect asbestos-containing materials associated with the site buildings and site building debris. Analysis of the bulk samples indicated 10 of the 66 samples contained asbestos concentrations greater than one percent. The concentration of asbestos in the roof material ranged from 10 to 60 percent. On April 21, 2015, the EPA and Tetra Tech collected composite soil samples from 25 delineated surface soil areas outside of the building and structures. These samples were collected to determine if surface soils located further away from the building exterior walls contained asbestos. Five of the 25 samples contained concentrations of asbestos ranging from 0.30 to 0.60 percent.
