Early 1980sAll production at the RMA ceases, and the mission shifts to environmental remediation and restoration. Any detected voids behind the casing were cemented to prevent possible contamination of other formations. Beginning in October 2012, testing has revealed that pollutants have escaped the Shell trenches and groundwater is likely coming into contact with the waste and migrating out of the trenches, the lawsuit says. An astonishing array of animals and habitats flourished onsix obsolete weapons complexes mostly for nuclear or chemical arms because the sites banned the public and other intrusions for decades. Mallard carcasses found to have higher levels of Dieldrin. Madison, the Fish and Wildlife Service historian, said the refuges are salvaging something valuable from ecological devastation. The magnitude 5.2 event caused widespread minor damage in the suburban areas of northeast Denver. Air monitoring surveillance continued until the end of July 2009. Waste further down than 10 is left in place in the former areas where the basins, chemical sewers, manufacturing plants, disposal trenches once were. [14] The following data were derived from the Rocky Mountain Arsenal Medical Monitoring Program Surveillance for Birth Defects Compendium prepared by Colorado Department of Public Health and Environment and published in February 2010. During November 1967, the Denver region was shaken by five moderate earthquakes. So theres a huge downside to converting it into a wildlife refuge, because it allows residual contamination to remain in place, said Jeff Edson, a former Colorado state health official who worked on the cleanup. But CERCLA empowers Colorado to enforce federal standards, the lawsuit claims. 1943RMA employees work around the clock to manufacture mustard gas, Lewisite, chlorine gas and incendiary weapons. According to National Resource Damage Assessment, although the contamination has been reduced by the treatment efforts, the water in and around the arsenal may never be fully clean. Current Basin F liquid consists of very salty water that includes some metals, chlorides, wastewater and toxic organics. In the early 1960s, the U.S. Army began to lease out its facilities to private companies to manufacture pesticides. 1989The U.S. Army, EPA and Shell sign the Federal Facilities Agreement, which provides a framework for decision-making and for completing 14 Interim Response Actions (IRAs) while final cleanup plans are developed. Critics sayRocky Mountain Arsenalin Colorado illustrates the shortcomings of a cleanup designed to be good enough for a refuge but not for human habitation. Hanford where the cleanup has already cost at least $48 billion and hundreds of billions more are projected may be the most troubled refuge of all. Thousands of ducks died after coming in contact with its wastewater ponds in the 1950s. In September of that year, the Army began removing fluid from the Arsenal well at a very slow rate, in hope that earthquake activity would lessen.

In addition to the containment structures, the agreed-upon remedy directs that the entire area is subject to restrictions on land use in perpetuity, including residential development, agricultural use, any potable use of the groundwater, and any consumption of fish or game from the Arsenal. The U.S. Congress responded to the movement in 1980 with the creation of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), most commonly referred to as a Superfund. The CDPHE issued the Army a notice of non-compliance, claiming its containment and treatment measures were not working. All manufacturing activities ended in 1982. independent local journalism in Denver. U.S. Rocky Flats National Wildlife Refuge, a former nuclear weapons plant northwest of Denver, opened to hikers and cyclists last September, but some activists question whether its safe. The Army replied by indicating federal authorities should regulate the arsenal superfund site through the CERCLA, and not state environmental authorities. The Rocky Mountain Arsenal (RMA) is a former chemical weapons manufacturing facility located just outside and northwest of the Denver, Colorado metropolitan area (Figure 21). Fish and Wildlife's Rocky Mountain Arsenal website. However, when the Basin F liquids were actually introduced, the process required more time than anticipated to complete because of the impermeability of the rock. 1941Japan attacks Pearl Harbor, and the United States enters World War II. In 2004, 5000 acres along the perimeter of the site were deleted from the National Priorities List of Superfund sites to establish the National Wildlife Refuge. 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. Photo source: Denver Post 1942The U.S. Army establishes the Rocky Mountain Arsenal to produce chemical weapons as a war-time deterrent. Residents may see flames, too, but are asked to not call 911 for this reason. Some waste disposal pits presented short-term hazards sufficient to preclude their excavation. Other demographics of the mother were gathered as well. Many of the conversions came after the first and second world wars. Just watch where you step. In the early 1960s, the U.S. Army began to lease out its facilities to private companies to manufacture pesticides. [citation needed]. Fish and Wildlife Service, and Shell Oil for failure to obtain a proper-post closure permit for Basin F, a section of the Rocky Mountain Arsenal. More by The Associated Press, Got a story tip? From 1964 -- 1966, waste was removed from an isolated section of Basin F and was combined with waste from a pre-treatment plant, located near Basin F, and then pumped into the well. (1 of 9) SITE HISTORY - Rocky Mountain Arsenal was listed on the NPL in 1987. The Rocky Mountain Arsenal, a manufacturing center of United States chemical weapons, is located in Commerce City, Colorado. 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. 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. A .gov website belongs to an official government organization in the United States. Also, they noted that if all groundwater were to be cleared for human consumption, the cost would be $500 million annually. The Rocky Mountain Arsenal manufactured chemical weapons including mustard gas, napalm, white phosphorus, lewisite, chlorine gas, and sarin. Rocky Mountain Arsenal National Wildlife Refuge (credit: CBS) Nick Kaczor and his team were also out -- trying to find the black footed ferrets. Slighter rumblings (below magnitude 3.0) occurred throughout the remainder of 1966, and through the first week of April 1967. The Rocky Mountain Arsenal National Wildlife Refuge has been transformed from a 17,000+ acre facility used for weapons and chemical manufacturing into a beautiful nature sanctuary. After the war, it became a bustling center of industrial activity -- a top-secret center that created a lot of dangerous waste. [20] In the case of Rocky Mountain Arsenal, total indirect cost was not estimated at all. Known today as an urban national wildlife refuge, the Rocky Mountain Arsenal is one of the most studied environmental cleanup sites in the country. Researchers have not examined the health risks to wildlife at the cleaned-up refuges as extensively as the potential danger to humans, but few problems have been reported. The Colorado Department of Public Health and Environment established monitoring systems throughout various locations of the RMA. State and federal officials say its safe, but skeptical activists filed a lawsuit saying the federal government didnt test the refuge carefully enough. A local shock awakened a few persons in Commerce City November 25. the Rocky Mountain Arsenal Disposal Well By D. B. Hoover and J. [4], The Arsenal's location was selected due to its relative distance from the coasts (and presumably not likely to be attacked), a sufficient labor force to work at the site, weather that was conducive to outdoor work, and the appropriate soil needed for the project. 1943From 1943 to 1946, the Rose Hill Prisoners of War Camp houses captured German soldiers at the RMA.

A small herd of wild bison was introduced to the refuge in March 2007 as part of the USFWS Bison Project. 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. Exchanging animals among smaller herds. Solid and liquid chemical hazardous wastes were disposed of in trenches, burn pits and pooled in open basins covering wide areas. Several were felt, but none caused damage until the window breaker that surprised Dupont and Irondale on the night of December 4. The U.S. Army constructed the Arsenal in 1942 to develop chemical weapons as a deterrent against the Axis Powers. Much of the site is now protected as the Rocky Mountain Arsenal National Wildlife Refuge. 2004After the EPA certifies that cleanup actions are complete, the U.S. Department of Defense transfers 5,000 acres of RMA land to the U.S. Department of the Interior to officially establish the Rocky Mountain Arsenal National Wildlife Refuge. Damage on a lesser scale occurred throughout the area. It was also helpful that the location was close to Stapleton airfield, a major transportation hub.[5]. CERCLA was a tax imposed on chemical and petroleum industries. 2007The EPA honors the RMA with its national Land Revitalization Award. The Army needs to find a way to clean up the depleted uranium safely.. Additionally, ordnance (including incendiary munitions) was manufactured and tested, and asbestos and polychlorinated biphenyls (PCBs) were used at RMA. Due to the early completion of this program, the Army realized a savings of 300,000 dollars. By the end of December 1962, 190 earthquakes had occurred. Who makes the best hot chicken sandwich in Denver?

The U.S government acquired the Arsenal land in 1942 to manufacture chemical warfare agents, including mustard gas and incendiary munitions, for use in World War II. Restrictions on well water use, residential development, consumption of fish and game from the arsenal, and agricultural use of the arsenal will exist in perpetuity until further scientific research is completed at the site. [citation needed] The site was operated by the United States Army throughout the later 20th century and was controversial among local residents until its closure in 1992. Provisions for a permanent water supply for off-post residents affected by arsenal groundwater contamination. The deep injection well was closed in 1985 and Basin F was closed in 1988 [10] After 42 years of chemical manufacturing, in 1984, the United States Army began to inspect the level of contamination at Rocky Mountain Arsenal (RMA). Today, only the foundation of a watch post from Rose Hill is visible, and then only when pointed. An acoustical ceiling and light fixtures fell at one school. The contamination of the underlying alluvial aquifer occurred due to the discharge of waste into unlined basins. In 2009, the state of Colorado, Shell Oil Co., and the United States Army settled a lawsuit pertaining to damages to the states natural resources from past activities at the Rocky Mountain Arsenal that caused extensive contamination of soil and water at the site. 4300 Cherry Creek Drive South Denver, CO 80246, Colorado Health Information Data Set (CoHID), Office of Public Health Practice, Planning, and Local Partnerships (OPHP), Air Quality - Monitoring, Modeling and Data. It was felt at Laramie, Wyoming, to the northwest, east to Goodland, Kansas, and south to Pueblo, Colorado. The Army discontinued use of the well in Feb. 1966 because of the possibility that the fluid injection was triggering earthquakes in the area. selected for the Rocky Mountain Arsenal includes the removal of contaminated soil down to 10 over much of the contaminated area, and that contaminated overburden is contained in two hazardous waste landfills that remain on the site. Its not because the Department of Defense has some ecological ethic, said Havlick, author of a book about conversions, Bombs Away: Militarization, Conservation, and Ecological Restoration.. Over 1,300 earthquakes were recorded at Bergen Park between January 1963 and August 9, 1967.

Shell Oil Co. leased the property and manufactured agricultural pesticides in the South Plants complex from 1952 through 1982. Rated magnitude 1.5, it was not strong enough to be felt by area residents. In 1975, Colorado Department of Public Health and Environment ordered the Army and Shell to stop the non-permitted discharge of contaminants, to control the contaminated groundwater leaving the site, and to implement a monitoring plan. Brighton is 6 miles north, and Barr Lake State Park is about 5 miles northeast. The well was cased and sealed to a depth of 11,975 feet, with the remaining 70 feet left as an open hole for the injection of Basin F liquids. 1989The U.S. One monitoring project has demonstrated incremental improvements over time, and specifically measured 640 parts per billion (ppb) in 1987 and 55 ppb in 1989, while a different off-post monitoring well measured 138 ppb in 1985, 105 ppb in 1987, 14 ppb in 1988, and 6.7 ppb in 1989. Theyre not going to want to be in a place with chemical pollution or radiation problems., Email: newsroom@coloradosun.com 1943RMA employees work around the clock to manufacture mustard gas, Lewisite, chlorine gas and incendiary weapons. In April 2007 Dick's Sporting Goods Park, a soccer-specific stadium, was opened on part of the former Rocky Mountain Arsenal land that was transferred to Commerce City. 1984The U.S. Army conducts the RMA Remedial Investigation / Feasibility Study, which includes the systematic investigation of contamination and the development and evaluation of cleanupalternatives.

The Rocky Mountain Arsenal, located ten minutes outside of downtown Denver, Colorado, offers one of the most unique urban wildlife refuges in the country. Roughly 10 miles (16 kilometers) from downtown Denver, the arsenal was once an environmental nightmare where chemical weapons and commercial pesticides were made. [18] While it is difficult to capture the societal cost to clean up the site, the list of actions dealing with groundwater contamination listed by Mears and Heise include: Direct economic totals add up to approximately $111 million and this estimation does not include operation and maintenance costs. In 1942, during World War II, the U.S. Army bought 17,000 acres of farmland outside of Denver to develop chemical weapons to be used as a war deterrent.

(5 of 9), Mayor Pro Tem Ren Bullock, who also sits on the Board of Directors for the Friends of the Front Range Wildlife Refuges, stated "As a decades-long participant in transitioning this site from munitions manufacturing to wildlife sanctuary, I can honestly say the Refuge is an shining example of promises made, promises kept and should serve as the gold standard for how to make former Superfund sites benefit the communities in which they are located." The land has a unique story - it has survived the test of time and transitioned from farmland, to war-time manufacturing site, to wildlife sanctuary. Join the Westword community and help support The On-Post Record of Decision was signed in June 1996 and describes the cleanup plan for soils, groundwater and structures within the approximately 27-square-mile on-post Operable Unit. Then, on April 10, the largest since the series began in 1962 occurred; 118 windowpanes were broken in buildings at the Rocky Mountain Arsenal, a crack in an asphalt parking lot was noted in the Derby area, and schools were dismissed in Boulder, where walls sustained cracks. 1995-1996Following extensive community input, the Off-Post and On-Post Records of Decision (ROD) are signed. Fish and Wildlife Service andShell Oil Company. CERCLA also gave the Federal government the authority to respond to the release of life-threatening hazardous materials.[2]. Depleted uranium, a byproduct of nuclear fuel production, is used for armor-piercing shells.
