Time-Critical Removal Action:  Manufacturing/Processing/Maintenance – Electroplating, Metal Finishing

Baycote Metal Finishing (Baycote or the Site) began operation in 1982.  The facility electroplated and anodized steel and steel casings with zinc, cadmium, and chromium for the automotive, recreational vehicle, and trailer industries.  The facility ceased operations in January 2008, however, according to facility records approximately 111,000 gallons of waste remained on site at the time.  In October 2009, the Indiana Department of Environmental Management (IDEM) and the owner of the site entered into an Order to remove and dispose of all hazardous waste.  However, work ceased and in February 2010, approximately 50,000 gallons of waste remained on-site.

1.1.2.1 Location

The Baycote Metal Finishing Site is located at 1302 Industrial Drive in Mishawaka, St. Joseph County, Indiana 46544.  The geographical coordinates for the Site are 41°39’0.03” North latitude and 86°09’57.11” West longitude.  The Site is bordered by industrial properties to the north, east, and south and Industrial Drive and industrial properties to the west.  Residential properties are located approximately 700 feet to the west.  Seven churches and two schools are located within 1 mile of the Site. The St. Joseph River, a major surface water body that terminates in Lake Michigan, is located 0.85 mile northwest of the Site. 

1.1.2.2 Description of Threat

Abandoned and unknown waste in vats, pits, tanks, drums and containers was located throughout the building.  Many vats, pits, tanks and containers are open with contents exposed.  Animal prints were observed in material piles on the building floor.  Several drums are corroded and leaking onto the floor.  Evidence of previous spills was noted in several areas.  The building is in a deteriorating condition; a section of roof in the Wastewater Treatment Room had collapsed, exposing the room and its contents to weather.  Due to the roof collapse and holes in the roof in other areas, rain water has accumulated in several sections of the building.  Vats, totes, and containers that contain incompatible wastes (acids, caustics, cyanides) are present inside the facility.  Based on these conditions, nearby populations and the environment could be exposed to potentially hazardous materials if contaminants migrate off site.

1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results

U.S. EPA On-Scene Coordinators (OSCs) Theresa Holz and Jacob Hassan conducted a Site visit on November 21, 2011, with the St. Joseph County Health Department (SJCHD).  During the visit, the OSCs documented numerous tanks, drums, containers and spilled material on the floor.  The OSCs also observed containers labeled as acid, chromate, nitrate, hexavalent chrome, and cyanide.  The Site was in disrepair, with a portion of the roof collapsed inside the facility.    The containers were not organized, secured, or maintained in a manner necessary to prevent spillage, inter-mixture of potentially flammable or combustible materials, and/or release.  The containers also were not all properly or sufficiently labeled or identified, for safety purposes.

On December 12 and 13, 2011, the Superfund Technical Assessment and Response Team (START) and U.S. EPA OSCs Holz, Hassan, and Atkociunas, performed a Site Assessment including sample collection.  Activities performed during the Site Assessment included:

•           Documenting Site conditions;

•           Conducting air monitoring;

•           Inventorying drums and other small containers; and

•           Collecting samples from vats, pits, tanks, drums and containers and spilled material. 

U.S. EPA collected fifteen samples from drums, plating vats, small containers and spilled material and submitted them for analysis.

The Site Assessment documented numerous drums, plating vats, pits, tanks, small containers, and spilled material.  Drums and containers were labeled as acid, chrome, and caustic.  Numerous plating vats and other process equipment were documented inside the building. 

Analytical results from liquid sample BMF-WL02-121211 documented reactive cyanide and total cyanide at concentrations of 8,000 and 15,000 milligrams per liter (mg/L), respectively.  The analytical results from liquid sample BMF-WL05-121211 documented reactive cyanide and total cyanide at concentrations of 140 and 30,000 mg/L, respectively.  According to 40 CFR § 261.23 (a)(5), these samples represent a cyanide- or sulfide-bearing waste that, when exposed to pH conditions between 2 and 12.5 SUs, could generate toxic gases, vapors, or fumes “in a quantity sufficient to present a danger to human health or the environment.”  These two samples document cyanide bearing waste, which verifies the characteristic of a hazardous waste for reactivity (D003).

Analytical results from liquid samples BMF-WL04-121211, BMF-WL07-121211, BMF-WL10-121211, and solid sample BMF-WS02-121211 documented pH values of less than 2.  According to 40 CFR § 261.22(a), these waste samples represent material that meets the definition of characteristically hazardous waste for corrosivity (D002) because the pH value is less than or equal to 2 standard units (SU) or greater than or equal to 12.5 SUs. 

Analytical results from solid sample BMF-WS01-121211 documented a cadmium concentration of 83 mg/L.  This TCLP cadmium concentration exceeds the TCLP cadmium regulatory limit of 1.0 mg/L.  Therefore, according to 40 CFR § 261.24(b), this sample represent materials that meet the definition of characteristically hazardous waste for toxicity (D006).   

Analytical results from solid samples BMF-WS-02-121211, BMF-WS-03-121211, and BMF-WS-04-121211 documented chromium concentrations of 20,000, 420, and 300 mg/L, respectively.  These TCLP chromium concentrations exceed the TCLP chromium regulatory limit of 5.0 mg/L.  Therefore, according to 40 CFR § 261.24(b), these samples represent materials that meet the definition of characteristically hazardous waste for toxicity (D007). 

Analytical results from liquid sample BMF-WL08-121211 showed a flashpoint of less than 32 degrees Fahrenheit (°F).  According to 40 CFR § 261.21 (a), this waste sample represents material that meets the definition of characteristically hazardous waste for ignitability (D001) because the flashpoint is below 140 °F.

In a letter dated November 11, 2011, the St. Joseph County Health Department (SJCHD) requested assistance from the U.S. EPA to secure hazardous wastes left on-site.  SJCHD was concerned that the Site posed a significant threat to the health and safety of companies within the industrial park as well as the residential area located less than a 1,000 feet from the facility.  On February 23, 2012, the Director of U.S. EPA's Superfund Division approved an Action Memorandum approving funding for a time-critical removal action at the Baycote Metal Finishing Site.

On April 6, 2012, U.S. EPA issued a Unilateral Administrative Order to the potentially responsible parties to conduct a removal action at the Site.  The potentially responsible parties presented and inability to pay argument and indicated that they did not intend to conduct a removal action at the Site.  EPA began time-critical removal actions at the Baycote Site on May 29, 2012. 

Removal activities on Site will include: Develop and implement a Site Health and Safety Plan and Site Security Plan; Develop and implement a Site Work Plan, a Sampling Plan, Air Monitoring Plan and a Site Emergency Contingency Plan; Inventory and perform hazard categorization on substances contained in vats, pits, drums, and other containers; Perform sampling and analysis to determine disposal options; Consolidate and package hazardous substances, pollutants, and contaminants for transportation and off-site disposal; Dismantle and decontaminate process equipment and building components associated with the plating areas, as necessary; Transport and dispose of all characterized or identified hazardous substances, pollutants, or contaminants to a RCRA/CERCLA-approved disposal facility in accordance with U.S. EPA Off-Site Rule (40 CFR § 300.440); and  Take any other response actions to address any release or threatened release of a hazardous substance, pollutant and contaminant that the U.S. EPA OSC determines may pose an imminent and substantial endangerment to the public health or the environment.
