FOR IMMEDIATE RELEASE ENR FRIDAY, FEBRUARY 23, 1996 (202) 616-2771 TDD (202) 514-1888 JUDGE ORDERS LONG-AWAITED CLEANUP OF DENVER RADIOACTIVE WASTE SITE DENIES CITY'S ATTEMPT TO BLOCK CLEANUP WASHINGTON D.C. -- A federal judge in Colorado cleared the way today for cleanup of a radioactive waste site on the south side of Denver. The decision ends a two-year dispute between the United States and the City of Denver, which had sought to block the cleanup approved by the Environmental Protection Agency and the State of Colorado. S.W. Shattuck Chemical Company had begun work in 1992 to clean up the land scarred by decades of dumping of radioactive materials from an ore processing facility. But, cleanup of the radioactive property, part of the Denver Radium Superfund site, has been delayed since May 11, 1994 when Denver served a cease and desist order on Shattuck, the property's owner. The City of Denver was unhappy with the plan because the radioactive materials, though cleaned up, would remain on-site. After discussions with the city failed, the Justice Department, on behalf of the Environmental Protection Agency, took the city to court in August, 1994. In an order issued today, U.S. District Court Judge Wiley Y. Daniel found Denver's order to be unconstitutional, calling it "invalid" and "unenforceable" under the Constitution's Supremacy Clause. The judge reaffirmed the federal government's authority to clean up toxic waste sites under the federal Superfund law. The cleanup is expected to begin in the next 30 days. "We are very pleased by the judge's decision," said Lois J. Schiffer, Assistant Attorney General in charge of (MORE) the Department's Environment and Natural Resources Division. "We are now able to put in place the cleanup plan to protect the health and safety of the residents in the area." For several decades, various ores, including uranium, tungsten and radium, were mined from sites around the Denver area. In the process, radioactive materials were removed from the ores and dumped on-site, contaminating soils and groundwater. The various properties were combined into the Denver Radium Superfund Site and listed on the national priorities list or Superfund list in the 1980s. The radioactive materials in the soil emit gamma radiation that can cause cancer. Prolonged breathing of air polluted by gamma radiation can increase the risk of lung cancer. In 1992, after extensive study and public review, the Environmental Protection Agency and the State of Colorado selected a cleanup method involving the consolidation and immobilization of the contaminated soils at the Shattuck site. Pursuant to an EPA adminstrative order, Shattuck Chemical was directed to destroy contaminated buildings, dig up contaminated soils and place them in one location. The radioactive soils would then be turned into a cement-like block, capped and buried in the earth. At the time Denver issued the cease and desist order, Shattuck Chemical had already destroyed all of the contaminated buildings and had dug up contaminated soils to be buried. The case is United States v. the City and County of Denver, Colorado et al., civil action no. 94-D-2004. ### 96-065
