Work continues on the former National Vulcanized Fiber plant in Yorklyn, as the state of Delaware seeks partners for their plans for the site including possible residential and commercial development, with park land for recreational uses.
Matt Chesser, Planning Preservation and Development Section Administrator with the Delaware Department of Natural Resources and Environmental Control, said he is tasked with working on the redevelopment side from the state parks perspective.
The state purchased 40 acres of the 80-acre site for $2.6 million following NVF’s bankruptcy in 2008.
In the past four months, Chesser said he’s overseen the demolition of some of the roughly dozen or so buildings left, as well as the near-completion of the Gun Club Road portion of the project.
The biggest delay, Chesser said, was in waiting for power lines to be installed along Yorklyn Road, which was completed roughly two weeks ago. The entire portion of the Gun Club Road project, which will connect the new road with the brick pathway installed by DNREC on the site, should be completed in the next six to eight weeks.
“Right now, it’s 80 percent complete,” he said. “There are turn lanes that need to be installed into the site, and it will connect by the railroad tracks on the back end. It’s exciting for us, as it’s the next step to shut down the existing Gun Club Road, which goes over a contamination area.”
Chesser said they’re also working with area water supplier and manager Artesian to bring water to the site, noting that they have already surveyed old Wilmington road down and portions of the site.
While contamination remediation continues on the site, Chesser said that the main reason they’re working with Artesian is that it’s the cheapest option.
“If we had wells, that would require a treatment plan to produce enough water for domestic consumption and fire prevention,” he said. “By the time you create that and have (water) towers, it was easier and more cost effective to have them run lines.”
He added that Artesian has been looking at both the NVF site and the surrounding area as wellhead sites.
“If they had any (contamination) concerns they wouldn’t be doing that,” Chesser said.
SITE REMEDIATION
Project co-manager and DNREC hydrologist John Cargill said that they have conducted tests at an existing well on the Snuff Mill Road side of the site, and found that it was not contaminated with “anything to be of concern.”
He added that the shallow groundwater is still contaminated with zinc, and that they have been correcting the problem through the onsite remediation system since 2008.
“We’re keeping it out of the creek, which is a big concern,” Cargill said. “The zinc is not very healthy to be in the creek.”
He added that while any groundwater is in the aquifer and could it potentially make it to the supply portion it hasn’t in over “decades and decades of use,” and that it was “not very likely” to happen.
“We’re removing 600 to 800 lbs. of solid zinc waste per month,” Cargill said. “That means it’s not getting into the creek, and we are pulling it from areas that are most contaminated based on the processes that went on there.”
He added that while Artesian is considering well sites, they would not be located on main plant sites.
“From a public perception standpoint, having centralized water is a very easy selling point,” he said.
DNREC has spent $4 million in combined state and federal funds on the cleanup of the site, with FEMA providing a portion of those funds with a grant through their flood recovery program.
NEVER THE SAME
Hockessin Historical Society head Joe Lake said that while DNREC’s plans for the site are ambitious, they’re not likely to find a partner with the reach and impact of NVF.
“It’s not just a matter of jobs, which they certainly provided – it was the support they gave to organizations like the Lions and the Hockessin Fire Company,” he said. “You’ll never find that again.”
He also lamented the way certain things were handled in the time after the plant closed over seven years ago.
“There were one-of-a-kind pieces of machinery in there, things that were as tall as the buildings they were in, and they’re gone,” he said. “We would have liked to see some of that kept in some way, and some of the buildings, too.”
Chesser said that demolition is slated to begin again in autumn, with five to six buildings that still need to come down due to location and deterioration.
While the site has been largely free of “active work” in recent months, Cargill said that just because no one sees workers and machines onsite doesn’t mean things aren’t progressing behind the scenes.
“There is a lot of stuff to juggle in background, with the removal of asbestos, monitoring wells – all those things being done, but they’re not highly visible activities.” Cargill said. “When the community sees that things appear idle, they’re not idle at all.”
Chesser said the project is still moving forward and progressing, with 2016 expected to be a year of a lot of changes.
“We’re still working on creating private development partnerships, and working on outreach and potential tenants and other partners,” he said. “We just help by supplying them with information. Meanwhile, we’re working on the contamination, structural changes and recreational parts of the parks components.”
ABOUT NVF
The company now known as NVF was formed by the merger of American Vulcanized Fiber Company, the National Fiber and Insulation Company and the Keystone Fiber Company on Jan. 1, 1923, according to a 1979 article in the New York Times.
The company created numerous products over the years, including Forbon, which was used in guitar pickups, and Yorkite, which has a wood grain pattern printed directly on the vulcanized fiber material.
NVF struggled with environmental issues in its later years, with a facility in Kennett Square, Pa. identified as a Superfund site in the 90s, when the soil was found to be contaminated with polychlorinated biphenyl.
Polychlorinated biphenyl is a synthetic organic chemical that has a zero Maximum Allowable Contaminant Level in the United States, with known toxic effects as endocrine disruption and neurotoxicity, according to the European Journal of Endocrinology.
The main product at the Yorklyn facility was created by soaking the plant cellulose essential to producing vulcanized fiber in a zinc chloride solution; that in turn lead to a buildup of the mineral in both the soil and the groundwater immediately beneath the site.
