What's New?

Updated January 2012

We will no longer periodically update this Web page. In Federal Register notice 58 FR 15287 dated March 22, 1993, the EPA and the state of Colorado determined that this site poses no significant threat to public health or the environment and no further remedial measures are appropriate.

Site Description

The 15-acre Woodbury site is in Commerce City, Colorado, on the north Denver County line. A mobile home park is located one-third of a mile from the property, and about 3,000 people work or live within a one-mile radius.

Woodbury operated a pesticide production facility at the site from the late 1950s until 1971. Five years after Woodbury closed its doors, the local health department was alerted to contaminated storm runoff from the vacant lot. Soil samples revealed mainly chlorinated pesticides and some heavy metals and volatile organic compounds (VOCs). Samples of six wells in the vicinity found no evidence of groundwater contamination.

EPA added the site to the Superfund National Priorities List (NPL) in 1983.

Site Risk

Pesticides in the environment can cause a variety of acute toxic reactions, skin and eye irritations, cancers, birth defects and reproductive system disorders. In addition, pesticides in soil and groundwater can make the habitat unusable for birds, mammals, reptiles and native plants. The risk at this site has been addressed.

Cleanup Progress

These cleanup activities were completed in 1992 by the potentially responsible parties:

  • Excavating and off-site burning of the more heavily contaminated soil.
  • Excavating and transferring less contaminated soils and rubble to a permitted facility.
  • Destroying and transferring site structures to a permitted facility.
  • Backfilling site with clean soil and reseeding with native grasses.

With the contaminated soil removed, clean soil added and a native grass cover, the site is fully restored. The property is available for unrestricted use. EPA removed the site from the National Priorities List (NPL) in March 1993. No further operation and maintenance activities are needed.

Community Involvement

Community involvement plays an important role in the Superfund process. EPA uses a number of different tools and resources to promote effective, on-going, meaningful community involvement. The goals of the Superfund community involvement program are to:

  • Keep communities affected by sites informed throughout the cleanup process
  • Provide opportunities for communities to comment and offer their input about site cleanup plans
  • Facilitate the resolution of community issues tied to a site

No community involvement activities are ongoing.

EPA places a high priority on land reuse as part of its Superfund response program mission. The agency tries to select cleanup options that encourage and support future use of a site. EPA uses two fundamental methods to facilitate reuse of Superfund sites:

  • Exploring future uses before the cleanup remedy is implemented, an approach that gives the Agency the best chance of designing cleanup remedies to support the likely future use of a site
  • Working with landowners and communities to remove barriers not considered necessary for the protection of human health or the environment at those sites where remedies are already in place

One option for reuse is the siting of clean and renewable energy projects on contaminated (or formerly contaminated) lands. As part of this effort, EPA is evaluating the potential for energy projects on these properties and working with landowners and communities to identify ways to remove barriers to such projects.

The Woodbury Chemical site was featured in EPA's Superfund at Work publication in spring of 1994 as a success story now safe for economic redevelopment with unrestricted use: Success in Brief: Site Restored for Unrestricted Use in Colorado (PDF, 4 pp, 404K, about PDF).

Land Use Controls and Other Institutional Controls

Land use controls are the most common type of institutional control (IC). ICs are administrative or legal controls that help reduce the likelihood for human exposure to contamination. ICs can also help protect the integrity of the remedy. Examples of ICs are:

  • Zoning ordinances
  • Environmental covenants
  • Deed notices
  • Well-drilling restrictions
  • Building permits
  • Informational advisories

This site does not require ICs, which means there is no contamination remaining at the site that could result in an unacceptable exposure and/or remedy components at the site that could be damaged.

Five-Year Reviews

EPA or the lead agency conducts five-year reviews following the start of a Superfund cleanup when contamination is left on the site. These reviews are repeated every five years. We use these reviews to determine:

  • How the remedy is working
  • If the remedy remains protective of human health and the environment

Five-year reviews are not required at this site because there is no contamination remaining at the site.
