From 1950 to 1952, the Army constructed the North Plants complex to manufacture the nerve agents VX and GB, (also called sarin). The Denver series was forgotten, however temporarily, in October 1966, when a southeast Colorado tremor rocked a 15,000 square-mile area of that State and bordering New Mexico. Madison, the Fish and Wildlife Service historian, said the refuges are salvaging something valuable from ecological devastation. Known today as an urban national wildlife refuge, the Rocky Mountain Arsenal traces its beginnings to the Dec. 7, 1941, attack on Pearl Harbor, which brought the United States into World War II. The deep injection well was closed in 1985 and Basin F was closed in 1988 [10] Critics say Rocky Mountain Arsenal in Colorado illustrates the shortcomings of a cleanup designed to be good enough for a refuge but not for human habitation. By year end, the United States has out-produced the Axis Powers by 150 percent. A $7 billion cleanup concentrated on 2 square miles (5 square kilometers) where workers assembled plutonium triggers for nuclear warheads, and that area is fenced and closed to the public. The Army needs to find a way to clean up the depleted uranium safely.. Additional cement barriers were placed inside the casing across zones that could access water-bearing formations (aquifers).

Share sensitive information only on official, secure websites. All waste that was left in place is now interred beneath large-area engineered covers that prevent any intrusion into the waste that remains below. 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. 6:54AM. The Rocky Mountain Arsenal was a United States chemical weapons manufacturing center located in the Denver Metropolitan Area in Commerce City, Colorado. (9 of 9). An official website of the United States government. OVERVIEW - Just 10 miles northeast of Denver, Colorado lies one of the largest urban wildlife refuges in the country, an area that only 30 years ago was listed on the Superfund National Priorities List due to being contaminated by over 600 chemicals. Beginning in 1942, the Army used the 27-square-mile arsenal at 5650 Gateway Road in Commerce City for the manufacture and disposal of chemical warfare agents, and chemical and incendiary munitions. 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. He began working at the newspaper in 1998, after writing for newspapers in Mesa, Ariz., and Twin Falls, Idaho, and The Associated Press in Salt Lake City. Contaminants included solvents, metals, pesticides, and miscellaneous manufacturing-related chemicals. 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. biological agent at Rocky Mountain Arsenal was begun in August 1971 and was completed in mid-February 1973. All manufacturing activities ended in 1982. Photo source: Dave Showalter
North of the former Stapleton Airport and west of Denver International Airport, Adams County. [1], The environmental movement began in the United States in the 1960-1970s. CERCLA also gave the Federal government the authority to respond to the release of life-threatening hazardous materials.[2]. Not for the "stupid price" of $150 an acre foot. Shell Oil Co. leased the property and manufactured agricultural pesticides in the South Plants complex from 1952 through 1982. 1943RMA employees work around the clock to manufacture mustard gas, Lewisite, chlorine gas and incendiary weapons. Take the Rocky Mountain Arsenal Self-Guided Wildlife Drive This was the highlight of the park for us. 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. In 1984, the Army began a systematic investigation of site contamination in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), commonly referred to as Superfund. Statistically significant findings (p<0.01) of this study included demographic differences in the mothers as follows: median age 24, compared to 27 years of age in Colorado as a whole, higher percent of mothers who were white/Hispanic and black, mean education level of 11.8 years compared to 13.1 years in Colorado as a whole, fewer mothers who were married, and fewer prenatal visits on average. The Rocky Mountain Arsenal was placed on the National Priorities List of Superfund sites in July 1987. Known today as an urban national wildlife refuge, the Rocky Mountain Arsenal traces its beginnings to the Dec. 7, 1941, attack on Pearl Harbor, which brought the United States into World War II.. Waste further down than 10 is left in place in the former areas where the basins, chemical sewers, manufacturing plants, disposal trenches once were. In 1987, the RMA was placed on the National Priorities List (NPL) of Superfund sites. The U.S. Army constructed the Arsenal in 1942 to develop chemical weapons as a deterrent against the Axis Powers. Feds sue water company for rupture damaging Rocky Mountain National Park -- again, Family gets unexpected bill after Kaiser Permanente Colorado software error that resulted in refunds to thousands, Skygazers will have a great view Wednesday of two planets that look like they are almost touching. A small herd of wild bison was introduced to the refuge in March 2007 as part of the USFWS Bison Project. In 1982, all production at the site stopped, and the Arsenals mission changed to environmental cleanup and restoration. It remained controversial among residents until it was closed in 1992. The 17,000-acre site is 10 miles northeast of Denver. Groundwater treatment will continue until all water leaving the site meets state and federal standards. Now a majority are voluntarily adopting them. Access a text only version of the Rocky Mountain Arsenal Site Spotlight. Further testing revealed that the containment issue is an ongoing problem, the lawsuit says. But forty years ago, a series of quakes rocked the Denver area -- quakes caused not by Mother Nature, but by Uncle Sam. One of the lessees, Julius Hyman and Company, manufactures agricultural chemicals at the site. However, the Army estimates that the waste was a more dilute version of the Basin F liquid which is now being incinerated. 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. Waste that was left in place is now interred beneath largeengineered covers that prevent intrusion by humans or animals,and also preventfurther contamination of groundwater. 1962Treated liquid waste is injected into a deep well located more than 12,000 feet below the ground surface. The Army and Shell took remedial actions to prevent the contamination that includes the installation of the groundwater barrier system which treated approximately 1 billion gallons of water every year. It was also helpful that the location was close to Stapleton airfield, a major transportation hub.[5]. This resulted in subsequent earthquakes in Denver area. Coinciding with these activities, from 1946 to 1982, the Army leased RMA facilities to private industries for the production of pesticides. Its location was selected because it is far from the coast and it has sufficient labor force. The shock shuffled furniture around in homes, and left electrical wall outlets hanging by their wires at Irondale. The U.S. Army selected 17,000 acres of farm land just 10 miles northeast of Denver in Commerce City, Colorado, as the site of the new Arsenal. To read the report, click, Archives: Project Descriptions / Fact Sheets, Hosted by Defense Media Activity - WEB.mil. In 1986, it was discovered that the absence of human activity had made the area an involuntary park when a winter communal roost of bald eagles, then an endangered species, was discovered on site. Fish and Wildlife Service establishes a field office at the RMA to manage bald eagles and other wildlife. The animals were transferred from the National Bison Range in Montana. 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. Another group asked the courts to release documents from a 27-year-old criminal investigation into the weapons plant, hoping they will show whether the government tracked down and cleaned up all the contamination. A medical monitoring program to monitor the success of exposure prevention efforts during the environmental cleanup. These field activities began in the fall of 1997 and significant portions of the cleanup have already been accomplished. A more recent article in 2004 by Pimentel,[19] estimated the cost of removal pesticides from the groundwater and soil at the Rocky Mountain Arsenal by approximately $2 billion. The contaminated soils cleanup phase of the process was completed in 2010. The primary contaminants include organochloride pesticides, organophosphate pesticides, carbamate insecticides, organic solvents and feedstock chemicals used as raw products or intermediates in the manufacturing process (e.g., chlorinated benzenes), heavy metals, chemical warfare material and their related breakdown products and biological warfare agent such as TX. Many projects have attempted to clean contaminated groundwater at the Arsenal. 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. During the development of the remedy for the Arsenals contamination, there was a lot of public concern that the cleanup itself might pose a risk to the surrounding residents. U.S. Roughly 10 miles (16 kilometers) from downtown Denver, the arsenal was once an environmental nightmare where chemical weapons and commercial pesticides were made. The Army discontinued use of the well in Feb. 1966 because of the possibility that the fluid injection was triggering earthquakes in the area. These potential confounders are not clearly addressed in this report and may complicate the analysis as well as raise concern for disparities in exposure risk that is dependent upon demographic factors. The brochure contains general information, license requirements, fee requirements, and a list of fish species. First, the well casing was tested to evaluate its integrity. It was felt at Laramie, Wyoming, to the northwest, east to Goodland, Kansas, and south to Pueblo, Colorado.

But CERCLA empowers Colorado to enforce federal standards, the lawsuit claims. "They have a very distinctive emerald green eye shine. Depleted uranium, a byproduct of nuclear fuel production, is used for armor-piercing shells. How? [20] In the case of Rocky Mountain Arsenal, total indirect cost was not estimated at all. Fish and Wildlife Service, Walter Derr, The Associated Press. The Rocky Mountain Arsenal was placed on the National Priorities List of Superfund sites in July 1987. During 1968, ten slight shocks were felt in Colorado. Rocket fuel was blended on-site for the Titan and Delta missile operations.

Dietrich f. h,_ During the 1968 pumping tests at the Rocky Mountain Arsenal disposal well, the U.S. Geological Survey was responsible for moni wring earthquakes occurring in the area of the arsenal ami making chemical analysis of the fluids removed. 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. Telling stories that matter in a dynamic, evolving state. Further, there have been damages to the rural areas due to contamination resulting in livestock losses, and crop losses. [12] Though the cleanup of the site was considered complete in 2010, soil and groundwater monitoring practices occur every five years to ensure the effects of the clean-up remain. The Rocky Mountain Arsenal (RMA), a few miles northeast of Denver, was originally constructed and operated by the Chemical Corps of the United States Army. The Colorado Department of Public Health and Environment established monitoring systems throughout various locations of the RMA. 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). Exchanging animals among smaller herds. Further, in 1961, the Army constructed a 12,000-foot deep injection well for the disposal of wastes. 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 site was placed on the National Priorities List (NPL), a list of the most contaminated areas in the United States. Groundwater is also pumped and treated at the site. (credit: Rocky Mountain Arsenal/Twitter) That section borders 56th Avenue at the Gateway and Montbello neighborhoods. 1943RMA employees work around the clock to manufacture mustard gas, Lewisite, chlorine gas and incendiary weapons. 1969Powered by rocket fuel propellant manufactured at the RMA, Apollo 11 lands on the moon. 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. State officials say they want long-term and legally binding assurances. Most of the land areas now belong to the U.S. The Rocky Mountain Arsenal National Wildlife Refuge Act was passed in October 1992 and signed by President George H. W. Bush. The Rocky Mountain Arsenal manufactured chemical weapons including mustard gas, napalm, white phosphorus, lewisite, chlorine gas, and sarin. Soon after, Congress enacted legislation designating the RMA as a future national wildlife refuge. Mitchell first started writing the Cold Case blog in Fall 2007, in part because Colorado has more than 1,400 unsolved homicides. The military reserved the right to oust these companies and restart chemical weapon production in the event of a national emergency. 1995-1996Following extensive community input, the Off-Post and On-Post Records of Decision (ROD) are signed.

(2 of 9), CLEANUP - The remedy selected for the Rocky Mountain Arsenal included the removal of contaminated soil down to 10 over much of the contaminated area, which is contained in two hazardous waste landfills that remain on the site. Estimating exact direct and indirect impact of the contamination is very challenging as the cleaning and monitoring costs are complex. Soldiers test-fired millions of artillery rounds at the proving ground, some made of depleted uranium. The cleanup was completed in 2010 and five large parcels of land have been deleted from the NPL, creating opportunities for reuse development and expansion of the Refuge. (6 of 9), TOURISM - Nearly 500,000 people annually visit the 15,000-acre Rocky Mountain Arsenal National Wildlife Refuge where they can see more than 330 species of animals including bison, deer, bald eagles and black-footed ferrets. Finally, the Act provides for the transfer of some Arsenal land for road expansion around the perimeter of the Arsenal and 915 acres (3.70km2) to be sold for development and annexation by Commerce City. State and federal officials say its safe, but skeptical activists filed a lawsuit saying the federal government didnt test the refuge carefully enough. Some parts of the refuge have been deemed safe but visitors must watch a safety video and sign a waiver promising not to sue if theyre injured by an exploding shell. After the war, it became a bustling center of industrial. 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. 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. Fish and Wildlife Service enter into a unique public-private teaming arrangement called the Remediation Venture Office (RVO) to facilitate the safe, timely and cost-effective cleanup and transition of the site. Additionally, ordnance (including incendiary munitions) was manufactured and tested, and asbestos and polychlorinated biphenyls (PCBs) were used at RMA. Thousands of ducks died after coming in contact with its wastewater ponds in the 1950s. The U.S. Army permanently manages. 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. A lot of the environmental stories are kind of doomy and gloomy, and these are successful ones, something positive, he said. No significant increase was observed in congenital anomalies during the clean-up period compared to pre-clean up, although there are no baseline data prior to initial contamination events because data was not yet being collected and the population was very different at that time. The Army and Shell Oil Co. began conducting detailed site investigations in the 1970s to define the extent of contamination. Damage on a lesser scale occurred throughout the area. 1992Congress passes the 1992 Rocky Mountain Arsenal National Wildlife Refuge Act, which designates the site as a future national wildlife refuge. 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. Next, the injection zone at the bottom 70 feet of the well was closed by plugging with cement. Last week, on December 8, 2015, the Rocky Mountain Arsenal rounded up the bison herd to gather animals that had been selected for donation to the Crane Trust--a bison conservation .

For more information please visit U.S. The magnitude 5.3 tremor caused the most serious damage at Northglenn, where concrete pillar supports to a church roof were weakened, and 20 windows were broken. There is no appropriate standard by the EPA, but the state of Colorado has a standard treatment protocol for this chemical. The manufacturing of these weapons continued until 1969. They would be worse if they were surrounded by a fence and left off-limits for decades and decades, said David Havlick, a professor at the University of Colorado at Colorado Springs who studies military-to-wildlife conversions. After 42 years of chemical manufacturing, in 1984, the United States Army began to inspect the level of contamination at Rocky Mountain Arsenal (RMA). As cleanup actions were successfully completed, the U.S. Army transferred land to the U.S. If you have additional questions, please call 303.289.0300.

Is there a risk of cancer related to Rocky Flats contamination? The facility was built in 1942, in response to the outbreak of World War II in Europe. The arsenal's animals are intended to refresh bloodlines of the national park's herd, Rocky Mountain Arsenal Refuge Manager David Lucas told CBS4. A separate study of cancer incidence by the Colorado Department of Health did not find convincing evidence of increased cancer risk in people living in residential areas surrounding the arsenal,[15] although the study was made more difficult by the large demographic changes in the area and was also confounded by smoking and obesity rates. Despite the complicated and expensive cleanups, significant contamination has been left behind, some experts say. 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. In 1942, the US Army acquired 19,915 acres (80.59km2) of land on which to manufacture weapons in support of World War II military activities at a cost of $62,415,000. The defendants must build a system to actively dewater Shells trenches to prevent the mixing of effluent with groundwater, the lawsuit says.

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. Fish and Wildlife Service and the Army will retain areas where hazardous wastes are managed, such as the landfill and soil covers. In September 2010, the cleanup was considered complete, and the remaining portions of land were transferred to the U.S. The Rocky Mountain Arsenal was created out of farmland on the eastern edge of metro Denver during World War II to arm the U.S. Army.
