On March 4, 2010, the Ohio EPA requested assistance from US EPA Region 5 at the Custom Chrome Plating (CCP) Site in Dayton, OH. The site is the location of a former chrome plating facility. Abandoned wastes include chrome sludge, acids, chromic acid bath solutions and flammable liquids.
On March 10, 2010, U.S. EPA conducted a site assessment at the CCP Site and observed approximately 25 chrome plating vats and tanks and 100 55-gallon drums and other waste containers within the facility. During the site assessment, U.S. EPA collected 9 liquid waste samples and 2 solid waste samples from drums, plating vats and containers. Analytical results indicated seven liquid waste samples having a pH value of less than 2.0 standard units and therefore meet the criterion for hazardous waste by virtue of corrosivity as defined in 40 CFR 261.22. Analytical results indicated that five investigative samples have TCLP chromium concentrations greater than 5.0 mg/L, with a maximum TCLP chromium concentration of 11,900 mg/L, and therefore meet the criterion for hazardous waste by virtue of toxicity as defined in 40 CFR 261.24. Analytical results indicated that two investigative liquid waste samples have flash points of less than 140 ºF and therefore meet the criterion for hazardous waste by virtue of the characteristic of ignitability as defined in 40 CFR 261.21. Hazardous wastes identified at the Site exhibit the following characteristics:
• Corrosivity
• Toxicity
• Ignitability
Based on the analytical results and Site conditions observed during the US EPA Site assessment, the Site meets the criteria for a removal action pursuant to 40 CFR 300.415(b)(2).
The US EPA removal action was initiated on May 3, 2010. See POLREP 1 for details.
The US EPA removal action was completed on June 29, 2010. See Final POLREP for details.
