From Arsenal of Democracy to urban wildlife refuge, the RMA has been critical to achieving U.S. defense, space exploration, environmental remediation and conservation goals. Since there is no further use for the building, the Army will remove it as part of a larger effort to reduce the Armys footprint at RMA. As production declined at wars end, the U.S. Army leased some of the facilities to private companies, one of which Shell Oil Co. purchased, for the production of agricultural chemicals. The location was ideal, not only because of the proximity to the airport, but because of the geographic features of the site, it was less likely to be attacked. One of the lessees, Julius Hyman and Company, manufactures agricultural chemicals at the site. Another strong shock rumbled through the Denver area on November 14, 1966, causing some damage at Commerce City and Eastlake. Known today as an urban national wildlife refuge, the Rocky Mountain Arsenal is one of the most studied environmental cleanup sites in the country. The U.S. For more information please visit U.S. The end result was approximately 165 million gallons of Basin F liquid waste being injected into the well during the period from 1962 through 1966. Slighter rumblings (below magnitude 3.0) occurred throughout the remainder of 1966, and through the first week of April 1967.

Birth defects included in the analysis were: "total congenital anomalies, major congenital anomalies, heart defects, muscle and skeletal defects, and kidney and bladder defects," and these categories were inconsistent in reporting accuracy. More than 600 chemicals have been used or manufactured at the arsenal, including: Diisopropyl methylphosphonate (DIMP), a chemical unique to the Army's manufacture of nerve gas. EPA and the State concurred with the approach. "Without the support of multiple federal agencies including the EPA Commerce City would have not been able to leverage a remediated property into a true community asset." Fish and Wildlife Service to create and later expand the Rocky Mountain Arsenal National Wildlife Refuge. This legacy, they say, requires restrictions on where visitors can go and obligates the government to monitor the sites for perhaps centuries. In September 2017, the state of Colorado filed a lawsuit to sue the United States government for the right to control the contaminated areas of the RMA. A lock (LockA locked padlock) or https:// means youve safely connected to the .gov website.

It stipulates that the majority of the site will become a National Wildlife Refuge under the jurisdiction of the Fish and Wildlife Service when the environmental restoration is completed. At that time, liquid waste disposal methods were employed in an attempt to prevent the chemical contamination from spreading further including lining one of the basins with asphalt, and injection of the waste chemicals into a deep well, but these techniques were ultimately unsuccessful. Many of the surrounding neighborhoods have been provided with potable tap water from other areas of Adams county because of the potential effects of contaminated groundwater from wells. Structures that contain the contaminated soil at RMA are also actively monitored, along with surface water and biological resources. The Off-Post Record of Decision was finalized in December 1995 and its requirements consist of actions for off-site groundwater and soil. Secure .gov websites use HTTPS independent local journalism in Denver. Boulder sustained minor damage to walls and acoustical tile ceilings on April 27, 1967, as result of a magnitude 4.4 earthquake. The waste from the pre-treatment plant was generally a solution containing 13,000 parts per million sodium chloride (salt), with a pH ranging from 3.5 to 11.5. From 1943 to 1956, the US Army and Shell discharged wastes into the unlined basins resulting in the contamination of the South Platte River outside the Arsenal. The Arsenal also played a role in Americas space exploration by manufacturing the rocket fuel used to power the Apollo 11 flights. Since then, the US Army started to operate the site. Rocky Mountain Arsenal, among other post-military sites, was a top priority, establishing RMA as a superfund site. The Rocky Mountain Arsenal, a manufacturing center of United States chemical weapons, is located in Commerce City, Colorado. After the attack on Pearl Harbor and the United States entered World War II, the U.S. Army began looking for land to create a chemical manufacturing center.

The first of the major chemical demilitarization programs to be undertaken at Rocky Mountain Arsenal was the disposal of the obsolete [13], As part of the clean up of the RMA, much of the soil, up to 10 feet below the surface was removed from the site. The injected fluids had very little potential for reaching the surface or useable groundwater supply since the injection point had 11,900 feet of rock above it and was sealed at the opening. During removal of contaminated soil and construction of the remedy containment structures, air monitoring was conducted at multiple sites in the Arsenals interior and fence line, and several sites in the surrounding communities. A 14-year, $2-billion remediation effort begun in 1996 will turn most of the arsenal into a national wildlife refuge. Fish and Wildlife Service inventoried more than 330 species of wildlife that inhabit the Arsenal including deer, coyotes, white pelicans and owls. The military reserved the right to oust these companies and restart chemical weapon production in the event of a national emergency.

This program was designed to address potential Arsenal-related health concerns of those living in communities surrounding the Rocky Mountain Arsenal, including the southernmost portion of Brighton, Commerce City, Green Valley Ranch, Henderson and Montbello. In 1996, after a lengthy process in which site investigations were conducted and completed, an approach to remedy the chemical contamination at the Arsenal was set forth by the US Army. Baseline rates of congenital anomalies in the study area compared to Colorado as a whole did not show significant differences between populations. Some waste disposal pits presented short-term hazards sufficient to preclude their excavation. All manufacturing activities ended in 1982. Manufacturing and waste disposal practices used during these years resulted in extensive soil, surface water, sediment, groundwater and structures contamination, damage to trees and vegetation, and death to wildlife. This led the State of Colorado to take legal action over who has legal authority over RMA remediation efforts, payment of natural resource damages (NRDs), and reimbursement of costs expended for cleanup activities (response costs). 2011In cooperation with federal, state and local regulatory agencies, the U.S. Army permanently maintains 1,000 acres at the site containing the landfills, waste consolidation areas and groundwater treatment facilities. During the cleanup of the RMA, concern for air pollution from the hazardous materials was raised. The history of the Rocky Mountain Arsenal National Wildlife Refuge stretches back more than 60 years. For example, DIMP (diisopropyl methyl phosphonate) was one of the main contaminants in the area. "They have a very distinctive emerald green eye shine. The animals were transferred from the National Bison Range in Montana. Its radiation isnt strong enough to be dangerous outside the body, but its dust is a serious health risk if inhaled or swallowed, the U.S. Environmental Protection Agency says. Depleted uranium fragments are scattered on the firing range among 1.5 million rounds of unexploded shells, which makes cleanup dangerous and expensive. The Army and Shell Oil Co. began conducting detailed site investigations in the 1970s to define the extent of contamination. Additionally, some of this land was used for a prisoner of war camp (for Germancombatants) and later transferred to the city of Denver as Stapleton Airport expanded. The Friends of the Front Range Wildlife Refuges (FFRWR) is a community that supports the two largest national wildlife refuges in the Denver metro area-the Rocky Mountain Arsenal and the Rocky Flats National Wildlife Refuges.

Access a text only version of the Rocky Mountain Arsenal Site Spotlight. From 1962 -- 1963, the fluids were pumped from Basin F into the well. The purpose of this Natural Resource Damage Assessment Plan is to document the State Trustees' basis for conducting the damage assessment that provided the basis of the lawsuit and to set forth the proposed approaches for quantifying harm to natural resources and calculating the damages associated with those injuries. When the cleanup was completed, it was clear that no Arsenal chemicals had been released into the air that exceeded the health-protective levels established for the site since the environmental cleanup began in October 1997. There are multiple paved, boardwalk, or gravel trail options with a variety of lengths and difficulty levels available. [8][9] The well remained unused until 1985 when the Army permanently sealed the disposal well. MORE: Federal prosecutors say they cant find files on investigation into Rocky Flats nuclear arms plant.
