Public Comment Period: Draft Restoration Plan - Shattuck Chemical, Denver

Date Posted: November 25, 2009

The Draft Restoration Plan and Environmental Assessment (RP/EA) for the Shattuck Chemical Restoration is now available. The Service, on behalf of the Department of the Interior, is proposing restoration actions within the South Platte River watershed to address known and potential impacts to migratory birds and their habitats resulting from environmental contaminants released from the Shattuck Superfund Site located in southwest Denver, Colorado.

The long-defunct Shattuck Chemical facility operated from 1917 to 1984. The company processed radium, uranium, molybdenum, rhenium and other heavy metals. These operational activities resulted in releases of hazardous substances from the site to South Platte River watershed environments. The Shattuck site is designated as Operable Unit 8 of the Denver Radium Superfund site. The U.S. Environmental Protection Agency (EPA) placed Denver Radium on the National Priorities (Superfund) List on September 8, 1983.

The proposed actions covered in this RP/EA outline projects that would be performed at Overland Pond Park in the Denver metro area and on private lands along the South Platte River on Colorado’s eastern plains.

Restoration actions to be implemented at Overland Pond Park will restore native plant communities surrounding Overland Pond and the adjacent South Platte River riparian habitat; provide improvements within the park to enhance educational opportunities that emphasize migratory birds; and incorporate volunteer efforts to include the community in the restoration efforts. The Greenway Foundation will provide overall management, supervision, and coordination for the Overland Pond Park project, and will serve as project lead for Denver Parks and Recreation as landowner.

Wildlife habitat improvement along the urban river corridor will restore aquatic, riparian, wetland and terrestrial habitats to benefit migratory birds - waterfowl, shorebirds, passerine songbirds and raptors - and increase healthy bird populations to, or hopefully exceeding, the levels prior to the hazardous chemical releases. The restored habitat will also provide enhanced opportunities for citizens to engage in wildlife-related activities such as bird-watching, volunteering, and learning about the river ecosystem.

Restoration actions on the eastern plains will restore and enhance multiple types of wetland habitats that especially improve spring and fall stop-over migration habitats and breeding habitats for migratory waterfowl, shorebirds, and wetland-dependent songbird species. The Service is soliciting information from all interested parties regarding the draft RP/EA. . All comments and scientific information must be received by December 23, 2009. Copies of the Draft RP/EA will be available for review at the Decker and Athmar branches of the Denver Public Library and at the U.S. Fish and Wildlife Service’s Colorado Field Office (134 Union Boulevard, Suite 670). The draft document is also available on the Service’s internet web site at:

Written comments should be sent to Laura Archuleta, U.S. Fish and Wildlife Service, Saguache Field Office, 46525 Highway 114, Saguache, CO 81149. Comments may also be sent via electronic mail to
