Bishop Tube Development Proposal
The Bishop Tube Site is a former metals processing plant located in East Whiteland Township, PA. The site is bordered by Little Valley Creek, a tributary to the exceptional value Valley Creek. Portions of the site are wooded. As a result of the historic uses at the site it has been designated as a Brownfields site.
Groundwater, soil and surface water at the Site are contaminated with TCE, which is classified as a probable human carcinogen by the EPA, and related products. TCE is chlorinated solvent and one of the problematic volatile organic compounds (VOCs) identified at the site, first in 1987. Chlorinated solvents are dense non-aqueous phase liquids, or DNAPLs. They are denser than water and have a low solubility. However, they are sufficiently soluble to cause a problem in both ground and surface water. The EPA maximum contaminant level (MCL) for TCE is 0.005 mg/l, with a zero desirable concentration (https://www.epa.gov/ground-water-and-drinking-water/table-regulated-drinking-water-contaminants#Organic, visited 2/18/17). EPA lists it as a discharge from metal degreasing sites or other factories and that it causes liver problems and an increased risk of cancer (Id.). Related compounds could include 1,1,1-trichloroethane and 1,1,2-trichloroethane (Id.).
Constitution Drive Partners, the current owner, is proposing a residential development at the site. They want a $1 million grant of state funds to undertake a partial remediation of the site so they can cut the trees, alter the landscape and build over 200 residential townhomes. Saturated soils and groundwater, including discharges to neighboring Little Valley Creek, would remain with plans for full remediation unknown.
The Delaware Riverkeeper Network opposes the project. We are joining the community in calling for full remediation of the site, at the expense of the known responsible parties, the natural woods, wetlands and creek protected, and the property turned over to the community as preserved natural open space.
The 13.7 acre Bishop Tube site (located in Chester County, PA, on the east side of Malin Road, south of US Route 30) has been abused by industry for over 50 years. The site, formerly used to process precious metals and fabricate tubing and pipeline products, is heavily contaminated with chlorinated solvents, acids and heavy metals. This contamination has impacted neighboring communities and the environment.
Rather than continue the abuse, and destroy all the natural beauty of the site for a massive, oversized, development, the community wants the site contamination fully cleaned up by responsible parties and the site protected as natural open space. Protection will benefit all who live around the site in Frazer, Malvern and East Whiteland, and will benefit all who appreciate, enjoy, and live along Little Valley Creek, tributary to Valley Creek, the stream directly in jeopardy from the proposal.
Contaminants currently at the site include TCE, nitric and hydrofluoric acids; various oils; and other hazardous materials not properly handled or disposed of. Industrial operations began in 1951. The plant closed in 1999.
While the site is dangerously contaminated, there is also beautiful nature worthy of saving. Woodlands, wetlands and Little Valley Creek, part of the exceptional value Valley Creek watershed, grace the location as well.
The proposed development, including approximately 200 new homes, would cut trees, damage the creek and wetlands, and only partially address contamination at the site. Saturated soils and groundwater would remain highly contaminated. Contamination would continue to affect the surrounding environment and community, including ongoing discharges of contaminated groundwater to Little Valley Creek. It is unknown if full remediation would take place under this current plan.
