Atlantic Wood Industries, Inc

Fact Sheet: June 1995, Proposed Plan

EPA Issues Proposed Plan

On June 9, 1995, the U.S. Environmental Protection Agency (EPA) released its Proposed Remedial Action Plan (Proposed Plan) for the Atlantic Wood Industries Superfund Site, located in Portsmouth, VA. This Proposed Plan summarizes the results of recent environmental studies at the site. It also presents cleanup alternatives and describes EPA's recommended course of action for cleaning up the site.

Proposed Plan

As with many Superfund sites, the environmental problems at the Atlantic Wood Site are complex. As a result, site studies and cleanup have been organized into separate units. The Proposed Plan discussed in this fact sheet addresses the primary areas of soil, sediment, and Dense Non-Aqueous Phase Liquid (DNAPL) contamination at the site. DNAPLs are heavy liquids that exist beneath certain surface areas at the site. These liquids are related to creosote, which is a chemical used in the wood-treating industry. The potential cleanup of other areas (site impacts to groundwater and the Elizabeth River) will be studied separately. The site was divided into separate units because soils, sediments, and DNAPLs are a continuing source of environmental contamination. In addition, more investigation and studies are needed to determine proper clean- up actions for groundwater and the River.

EPA seeks your comments and questions on the Proposed Plan during the public comment period and at the public meeting (see box below). EPA encourages your participation and welcomes your input. The complete Proposed Plan, along with technical documents relating to the site investigations and studies, can be found in the public information files listed on page 3. Unlike the Proposed Plan, this fact sheet is not a legal or technical document. This fact sheet reviews the information in the Proposed Plan, outlines EPA's recommended actions, reviews the site history, and tells you how to get further site-related information. All bold underlined words are defined in the glossary inserted in this fact sheet.

Site Contamination

A Remedial Investigation was conducted at the site to determine the nature and extent of contamination. Soils, sediments, and groundwater were sampled and analyzed. In order to better evaluate clean-up actions, the site was divided into the five distinct Units described in the box below.

Soil samples revealed polynuclear aromatic hydrocarbons (PAHs), pentachlorophenol (PCP), and metals such as arsenic, copper and zinc. PAHs (compounds related to creosote) and PCP were used in the wood-treating process at the site. Several groundwater samples in the upper aquifer revealed the presence of DNAPLs. Aquifers are areas below the surface of the ground that hold and transport groundwater.

In addition to the Remedial Investigation, a Risk Assessment was conducted for the site. The Risk Assessment evaluated the potential risks posed by site contamination. The evaluation concluded that the site, in its present condition, poses a potential threat to human health and the environment.

A Feasibility Study was also conducted to evaluate the available technologies to clean up site soils, sediments, and DNAPLs. For soils and sediments, two general categories were evaluated. One category deals with treatment alternatives, and the other category deals with disposal-only alternatives. For DNAPLs, various recovery technologies were evaluated. All clean-up alternatives include surface water, groundwater, and sediment monitoring; deed restrictions; erosion controls; dust controls; and treatability studies. The alternatives EPA evaluated are listed in the table below and are numbered to correspond with the Proposed Plan.

EPA's Preferred Alternatives

After carefully reviewing all the alternatives, EPA has chosen a recommended course of action for each Unit. EPA evaluated each alternative against several criteria before choosing the preferred alternatives. (See box in right hand column for EPA's list of criteria.) The preferred alternative for each Unit is summarized below.

UNITS 1 & 2

On-site Soils and On-site Sediments - Alternative 7: Excavation, Engineered Land Treatment, and Backfill

This alternative involves excavating and biologically treating approximately 20,000 cubic yards of soil, and 564 cubic yards of sediments. The soils and sediments would be placed in an on-site treatment plot and mixed with nutrients and water which would help microorganisms break down the contaminants. Once the required clean-up levels are achieved, the soil and sediments would be returned to the general area from which they were excavated. If the required clean-up levels are not achieved, a back-up plan would be implemented. (See the Proposed Plan for details.)

UNIT 3

DNAPLs - Alternative 11: Extracting DNAPL for Reuse

This alternative calls for the installation of new recovery wells and the use of existing wells for the purpose of pumping or bailing out DNAPLs from the underground areas. This alternative would reduce the concentrations of DNAPLs underground and in the groundwater.

UNITS 4 & 5

Southeast Ditch Sediments and Waste Lime Area Soils- Alternative 3: Excavation and Off-site Landfill

This alternative involves excavating an estimated 250 cubic yards of sediments and 2,370 cubic yards of soils and transporting them to a regulated off-site landfill for disposal. Following excavation, the areas would be backfilled with clean soil and graded to control drainage.

EPA's preferred alternatives are only recommendations at this time. EPA welcomes community input on all of the alternatives during the public comment period. Based on input received, EPA may change its preferred clean-up alternatives. (See Public Comment Period on Page 1.)

Site Background

The 47.5-acre Atlantic Wood Industries Superfund Site is located on the industrialized banks of the South Branch of the Elizabeth River in Portsmouth, Virginia. The site operated as a wood-treating facility from 1926 to 1992. Chemical compounds that were used in the treatment operations such as polynuclear aromatic hydrocarbons (PAHs) and pentachlorophenol (PCPs), have contaminated soils, sediments and groundwater at the site.

Based on environmental investigations of the site, EPA determined that the site posed a potential threat to human health and the environment, and therefore placed the site on EPA's Superfund National Priorities List on February 15, 1990. Under EPA oversight and in consultation with the Virginia Department of Environmental Quality, Atlantic Wood Industries conducted a Remedial Investigation and Feasibility Study of the site. Atlantic Wood Industries has also conducted initial clean-up actions at the site whereby a leaking storm sewer was re-lined to prevent the spread of subsurface contamination to an adjacent inlet. Also, approximately 520 cubic yards of heavily contaminated inlet sediments were removed and replaced with clean fill.
