1.1.1 Incident Category
Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Incident Category:  Manufacturing/Processing/Maintenance - Lumber and wood products/wood preserving/treatment

1.1.2 Site Description
The site is the former Hoosier Wood Preservers.  The site is 7.75 acres in size and has ten buildings, including process buildings, storage buildings, a garage, and office. 

The facility operated from 1969 to 2013 as a wood treating business that used chromated copper arsenate (CCA) and borate in pressurized wood treatment cylinders.   Historically, the facility also used creosote and pentachlorophenol to treat wood.  The facility has been abandoned since 2013. 

1.1.2.1 Location
Hoosier Wood Preservers is located at 3605 Farnsworth Street in Indianapolis, Marion County, Indiana.  Site coordinates are 39.7224100 degrees north latitude and 86.2212300 degrees west longitude.  The site is located approximately 3.5 miles southwest of downtown Indianapolis.

The surrounding area is primarily industrial, although commercial properties are located to the south.  Residential properties are within 200 feet to the east and northeast.

1.1.2.2 Description of Threat
Arsenic was present in soil, material on the ground, and fire debris at a maximum concentration of 272,000 milligrams per kilogram (mg/kg), above the Environmental Protection Agency's (EPA) industrial Removal Management Level (RML) of 300 mg/kg. Arsenic is a hazardous substance as defined by section 101(14) of CERCLA. Laboratory analytical results confirmed the presence of arsenic at concentrations exceeding relevant regulatory and screening levels.  Hazardous substances represented an actual or potential exposure threat to nearby human populations. Possible release mechanisms for arsenic in soil included fugitive dust generation; tracking of contaminated soil, ash, and material on the ground; and dermal contact with contaminated material. Exposure routes included direct contact, ingestion, and inhalation of arsenic particles. Potential human receptors included trespassers, emergency response workers, future site workers, and nearby residents. There was evidence of trespassing at the site.  Residential properties are located within 200 feet of the site.

• Shipped non-hazardous treated soils to Twin Bridges landfill in Danville, Indiana; 
• Shipped highly-contaminated green solid material and liquid to Petrochem Processing in Detroit, Michigan;
• Placed clean fill at the former Treatment Building excavation;
• Conducted air monitoring for particulates;
• Decontaminated equipment; and
• Demobilized equipment and personnel.

2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
