Cleanup complete at Allied Chemical Corp. site

By Jessica Coleman

FRONT ROYAL — Fieldwork at the Allied Chemical Corp. Superfund site, adjacent to the Avtex Superfund site, has been completed, according to the U.S. Environmental Protection Agency.

The EPA conducted a final walk-through in mid-June to determine whether the site meets all standards. It passed the inspection, and all cleanup activities are now complete, said Eduardo Rovira, EPA on-scene coordinator.

"As far as the action, it's done," Rovira said. "As far as the EPA, it's done."

According to the EPA, Allied produced sulfuric acid at the site from 1945 to 1986. General Chemical Corp. became the owner/operator in May 1986, but sulfuric acid was still produced. Then, in August 1986, Avtex Fibers Inc. purchased and ceased production at the site, using it instead as a storage and transfer facility for the sulfuric acid used in its production of rayon at the Avtex plant. When Avtex filed for bankruptcy in 1989, the site was abandoned.

At that time, EPA began monitoring the conditions at the 78-acre site, which progressively deteriorated until in 1998 a unilateral administrative order called for the remediation process to begin.

The order states that in September 1998, the director of EPA Region III's Hazardous Site Cleanup Division "determined that a threat to public health, welfare and/or the environment exists due to the actual or threatened release of hazardous substances from the site."

The concern of the EPA, according to the order, was access to the site by the public and transfer of the chemicals to the river. The site is bordered by the South Fork of the Shenandoah River, and there are residences within a half-mile.

"Due to the proximity of the residences and due to the fact that the South Fork of the Shenandoah River, which borders the site, is used as a recreational waterway, there is a potential for human exposure to the hazardous substances at the Site," the document reads. "Additionally, if hazardous substances in the ponds are not removed, they may migrate to the South Fork of the Shenandoah River."

In 2004, the property was transferred to Honeywell International as a result of a bankruptcy settlement with General Chemical, said Victoria A. Streitfeld, a spokesperson for Honeywell, in an e-mail.

When the cleanup began, the site consisted of an abandoned sulfuric acid manufacturing plant, which was demolished in 2001, according to Streitfeld. The fenced area of the site contained numerous processing tanks, piping and buildings. Numerous containment ponds and two areas believed to have been used to dump wastes lay in an unfenced portion portion of the site.

According to the EPA's Web site, updated in December 2007: "Materials which remain at the site include waste materials from the production of sulfuric acid, including polycyclic aromatic hydrocarbons (PAHs), corrosive and flammable materials. Materials in the ponds, disposal areas and in the process equipment may release or may have been released into the environment."

"There was a lot of sulfur," Rovira said. "That's basically what they did last year — remove any soils that contain sulfur."

Honeywell's contractors rece-ntly excavated, backfilled and graded and seeded two small ponds, a bermed pit, a perimeter engineered surface-water drainage ditch and a process-water discharge pit.

"Honeywell has completed the removal of contaminated soil from the former Allied Chemical Site on Kendrick Lane," Streitfeld said. "The investigation and remediation of the site was conducted under the supervision of the U.S. Environmental Protection Agency. All of the soil was taken to an approved, licensed disposal facility in covered, lined trucks."

Once the removal was done, the vegetation at the site came up for review. In May, workers made sure that grasses and plants emplaced last fall were growing well and worked on any problem areas.

Now the only question that remains is what will be done with the site once the EPA has given its approval.

"We will be working with local officials and the community to determine the appropriate reuse for the site," Streitfeld said.

However, no potential use for the Superfund site has yet been determined, she added.
