The Custom Design site is located at 46 South Street, Danbury, CT, on an approximately .5 acre lot which includes a two story cinder block building. The site is located in a residential/commercial neighborhood, with the closest residence adjacent to the west of the building. The site is bordered to the north by High Street and a residential property, to the east by South Street, and to the south by residential properties. The Connecticut Department of Environmental Protection (CTDEP) has been involved with regulatory and compliance issues with this now defunct printed circuit board plating shop since September, 2001. The owner has periodically undertaken portions of the necessary cleanup, removing some waste and consolidating others. In December 2001, the CTDEP asked the EPA’s Removal Program to assist with site clean up because of the current owner’s inability to fund the remaining portions of the site activities. On December 27, 2001, EPA visited the site with CTDEP representatives. More than 75 containers ranging in size from 55 gallon drums to 1 gallon pails where stored inside and outside the building. Approximately 25-55 gallon drums were stored haphazardly in a non restricted area at the parking lot of the site adjacent to the building. Portions of the interior concrete floors, under the former plating vats were visibly contaminated with powders and sludge. There where several vats, half to three quarters full, with unidentified liquids. There was also residual waste in the floor troughs, sump pump pits, pipes, lines, and on the walls. There were also four tanks ranging from 275-5000 gallon capacity that appeared to have product. On January 22, 2002, EPA returned to the site with contractor personnel to conduct a Preliminary Assessment and Site Investigation (PA/SI). The drums and other containers that were stored outside had been brought in the building by the owner. A number of containers were sampled to confirm the presence of acids/caustics. Seven drums and two trays were tested for pH, and the results varied from 0 to 13 on the pH scale. Three drums had a pH of 0, four drums had a pH of 13, and one plating tray had a pH of 1. The pH of four vats was tested; three had a pH of 2 and one had a pH of 4. Two floor sumps were also tested for pH, both had a pH of 3. According to 40 CFR §261.22 (a)(1) a solid waste exhibits the characteristic of corrosivity, if a representative sample of the waste has either of the following properties: a pH less than or equal to 2 or greater than or equal to 12.5. This designation renders this material a hazardous waste.
Based upon the amount of inventory and the field confirmation, EPA will conduct a removal action of the above mentioned plating wastes that are in containers and on various surfaces where they present a threat.
