Scherer/Chelsea Labs Facility) Rogers & Callcott Project Number: 93-121 Dear Mr. Watson: Rogers & Callcott Environmental (Rogers & Callcott) is pleased to submit this report detailing the closure of the infiltration gallery at the subject site. Closure was conducted in accordance with the Infiltration Gallery Closure Plan (August 28, 2023) approved by the Department on August 29, 2023. Rogers & Callcott subcontracted Innovative Environmental Technologies (IET) to grout the infiltration gallery and associated piping and remove the holding tank, flow control sump, and related conduit. The infiltration gallery was abandoned in place to minimize site disturbances for the current property owner and business operations. All work was completed between September 18 and September 20, 2023. Closure Activities In order to abandon the 4-inch discharge line from the infiltration gallery flow control sump that connects to the two 6-inch corrugated lines that run the length of the gallery, the 4-inch line was unearthed and cut close to the holding tank (Photo 1). A fitting was then attached to the end of the 4- inch line that allowed for approximately 500-525 gallons of neat cement grout slurry to be pumped from a grout plant through an injection hose through the 4-inch pipe and into the 6-inch corrugated lines using forced injection (Photo 2). The end of the 4-inch line leading to the gallery, from the holding tank, was also filled with standard concrete to completely block the pipe. The discharge line leading from the old infiltration gallery totalizer meter to the holding tank was abandoned similarly to the 4-inch line. The discharge line was unearthed and cut close to the holding tank (Photo 3), a fitting was attached, and approximately 25-50 gallons of neat cement grout slurry was pumped into the line using forced injection (Photo 4). The holding tank was then removed from the concrete pad and cut into three pieces to be disposed of along with the flow control sump (Photo 5). The conduit and wiring to the flow control sump were cut and removed (Photo 6). All wiring was taped and pushed into the wiring housing below the ground surface before being sealed with neat cement grout (Photo 7).

DPT rods were pushed approximately 16-18 feet below ground surface into the infiltration gallery at 16 different locations (Photo 8). These locations were spaced approximately 10 feet apart along the length of the infiltration zone. Approximately 70 gallons of neat cement slurry was injected through the DPT rods by forced injection at each of the 16 locations, totaling approximately 1,100 gallons of grout (Photo 9). Each of the 16 bore holes was then backfilled with neat cement grout once the injections were complete (Photo 10). Prior to leaving the site, all disturbed ground was reseeded and covered in straw (Photo 11). The old holding tank and the old flow control panel were disposed of in a dumper. We understand at this time that Catalent has fulfilled the requirements needed to close out the National Pollutant Discharge Elimination System (NPDES) Permit #00844344.
