Clairson Plastics Tank Closure Assessment Project


The Property was developed in 1975 by Moore-Handley, Inc., a residential contracting company. In 1978, Moore-Handley, Inc. sold the Property to Scotty’s, Inc. Scotty’s, Inc. operated a building material supply company at the Property from 1978 to 1979. From 1979 to 1982, Closet Maid, a closet shelving manufacturing facility, occupied the Property. Since 1982, the Property has been occupied by Clairson Plastics, an injection molding manufacturing facility. In 1989, Scotty’s, Inc. sold the Property to Clairson Plastics. AEC’s client, The Baraboo National Bank, obtained ownership of the Property from Clairson Plastics in 2011.

In June 2014, a consultant for a potential purchaser completed a Phase I Environmental Site Assessment (ESA) of the Property. The consultant’s inspection of the Property identified the presence of an underground storage tank (UST), concrete dispenser island, and vent pipe near the northwest corner of the loading bay area. A fill port for the UST and capped off fuel dispensing piping were visible, but no dispensing equipment was present. Interviews with onsite personnel revealed that the UST system had been present since the 1982, however, it was never used by Clairson Plastics. Review of the Florida Department of Environmental Protection (FDEP) storage tank databases revealed no registration for a storage tank system at the Property.

In July 2014, AEC completed a soil assessment at the Property in the area surrounding the UST. Based on available information and experience with sites in Marion County, AEC estimated the shallow groundwater at the Property to be greater than 25 ft bls, therefore, AEC’s assessment of the Property was limited to soil. No odors or staining were observed in any of the soil borings. Laboratory analysis of the soil samples identified no petroleum constituents exceeding the State’s Direct Exposure Residential Soil Cleanup Target Levels (SCTLs) specified in Chapter 62-777, FAC.

On July 30 & 31, 2014, AEC demolished the concrete dispenser island and excavated a 3,000 gallon UST in accordance with Chapter 62-761, FAC and FDEP’s guidance document titled “Storage Tank System Closure Assessment Requirements” dated April 1998. No odors, staining, or organic vapors were detected in the soil under and around the UST. No petroleum constituents were identified in soil samples collected adjacent to and underneath the UST. Since the UST system was unregistered, its origin and use were unknown, and no discharge had occurred, AEC recommended no further action respective to the UST system at the Property. A Tank Closure Assessment Report (TCAR) was prepared by AEC in August 2014.
