Ohio EPA Seeks Public Comments on Remediation Plan at Cincinnati Site

The preferred plan to remediate the former Phthalchem site in Cincinnati will be the subject of an Ohio EPA public hearing on Tuesday, June 4, 2019, at St. Bernard City Hall, 110 Washington Ave.

The meeting will begin at 6 p.m. with an information session, followed by a public hearing. The meeting will be in the lower level conference room.

During the information session, Ohio EPA representatives will present details and answer questions about the preferred plan. During the hearing, which will follow the information session, the public can submit comments for the record regarding the plan.

Multiple chemicals previously were manufactured on the site, which is currently vacant. The site includes two sections. One is the former facility production area; the other is Mill Creek, where off-property contamination has migrated.

The company presented Ohio EPA with multiple options to consider to prevent potential human exposure to contaminants. The preferred alternative includes a risk mitigation plan, maintenance of an existing asphalt cap and former building foundation to prevent direct contact with the soil. An environmental covenant would be placed on the deed to restrict future use of the site to commercial or industrial use, prohibit use of ground water and require a vapor intrusion pathway evaluation should any future structures be built on the site. The plan also requires continued operation of the current ground water interceptor system and slurry wall, long-term water monitoring and removal of floating liquid contaminants known as “free product.”

The preferred plan can be viewed online or at Ohio EPA’s Southwest District Office, 401 E. Fifth St., Dayton; call (937) 285-6357 to make an appointment.

Written comments on the preferred plan will be accepted at the hearing or may be emailed to Chuck Mellon, site coordinator, at charles.mellon@epa.ohio.gov or mailed to Ohio EPA Southwest District Office, 401 E. Fifth St., Dayton, OH 45402. Comments will be accepted until June 14.


The Ohio Environmental Protection Agency was created in 1972 to consolidate efforts to protect and improve air quality, water quality and waste management in Ohio. Since then, air pollutants dropped by as much as 90 percent; large rivers meeting standards improved from 21 percent to 89 percent; and hundreds of polluting, open dumps were replaced with engineered landfills and an increased emphasis on waste reduction and recycling.
