Question: Basin F was constructed by the United States Army in 1956, to provide for the disposal of contaminated liquid wastes from the chemical manufacturing operations of the Army and its lessee Shell Chemical Company, at which location, that's a United States chemical weapons manufacturing center located in the Denver Metropolitan Area in Commerce City, Colorado?
Context: The Tooele Chemical Agent Disposal Facility (also called Tooele Chemical Demilitarization Facility) or TOCDF, is a U.S. Army facility located at Deseret Chemical Depot in Tooele County, Utah that was used for dismantling chemical weapons. Destruction is a requirement under the Chemical Weapons Convention and is monitored by the Organisation for the Prohibition of Chemical Weapons.  Deseret Chemical Depot held 44% of the nation's chemical stockpile when processing began, and it had held some of these chemical munitions since 1942.  TOCDF was constructed in the early 1990s and began destruction of chemical agent-filled munitions on 22 August 1996.  As of September 2011, the facility had processed 99% of its stockpile.  TOCDF processed all of its VX, Sarin and mustard gas at its main facility; a smaller incinerator was installed west of the main plant in order to dispose of Lewisite-filled containers.  In advance of plant closing, two ponds were revitalized and the surrounded area reseeded as well as 29 miles of railroad being removed (out of 40-miles of rail in Deseret).  Disposal of all chemical weapons concluded on 21 January 2012.  It was the last depot to complete its disposal operations under the U.S. Army Chemical Materials Agency; although two other depots still store chemical weapons to be destroyed by the Assembled Chemical Weapons Alternatives program at Pueblo, Colorado and Bluegrass, Kentucky. Anniston Chemical Activity was a U.S. Army chemical weapon storage site located in Alabama.  The Army had stored approximately seven percent of the nation’s original chemical weapons stockpile at the Anniston Army Depot since the early 1960s.  In August 2003, the Army began disposing of these weapons at the Anniston Chemical Agent Disposal Facility.  Destruction of the base's stockpile of VX was begun on July 23, 2006.  By December 2008, all of the VX on site had been destroyed.  Destruction of mustard-filled munitions began on July 2, 2009 after several months of retooling.  By July 2010, it had destroyed by incineration 75% of the depot's total stockpile including all 437 tons (397 metric tons) of GB (sarin) and all VX nerve agent on site.  On September 22, 2011, the last mustard gas shells were burned, completing chemical weapons disposal at the facility.  The OPCW inspection team leader Mr.Zhang and facility representative signed the final inspection report.  The facilities were scheduled for dismantlement by about 2013 and some of the weapon-handling equipment was planned for transfer to the depots at Kentucky and Colorado.  Local government emergency departments are expecting to lose millions in annual funding from the federal government related to the presence of the chemical depot and as many as 1000 jobs will be cut on the base. The Rocky Mountain Arsenal was a United States chemical weapons manufacturing center located in the Denver Metropolitan Area in Commerce City, Colorado.  The site was completed December 1942, operated by the United States Army throughout the later 20th century and was controversial among local residents until its closure in 1992. The Blue Grass Chemical Agent-Destruction Pilot Plant (BGCAPP) is a chemical weapons destruction facility undergoing systemization, or testing.  The plant will destroy the chemical weapons stockpile at the Blue Grass Army Depot (BGAD), near Richmond, Kentucky.  The plant is dedicated to the destruction of 523 ST of nerve agents sarin (GB) and VX, and mustard agent, which constitute about two percent of the United States chemical weapons stockpile. The United States chemical weapons program began in 1917 during World War I with the creation of the U.S. Army's Gas Service Section and ended 73 years later in 1990 with the country's practical adoption of the Chemical Weapons Convention (signed 1993; entered into force, 1997).  Destruction of stockpiled chemical weapons began in 1985 and is still ongoing.  The U.S. Army Medical Research Institute of Chemical Defense, at Aberdeen Proving Ground, Maryland, continues to operate for purely defensive research and education purposes. The United States chemical weapons program began in 1917 during World War I with the creation of the U.S. Army's Gas Service Section and ended 73 years later in 1990 with the country's practical adoption of the Chemical Weapons Convention (signed 1993; entered into force, 1997).  Destruction of stockpiled chemical weapons began in 1985 and is still ongoing.  Alleged use of chemical agents by the U.S. in the Korean (1950–53) and Vietnam (1955-1975) conflicts has never been substantiated and there is no reliable evidence that the country ever used chemical weapons on either battlefield.  The U.S. Army Medical Research Institute of Chemical Defense (USAMRICD), at Aberdeen Proving Ground, Maryland, continues to operate. The destruction of Syria's chemical weapons began in September 2013 on the basis of several international agreements with Syria that stipulated an initial destruction deadline of 30 June 2014.  United Nations Security Council Resolution 2118 of 27 September 2013 required Syria to assume responsibility for and follow a timeline for the destruction of its chemical weapons and its chemical weapon production facilities.  The resolution bound Syria to the implementation plan presented in a decision of the Organisation for the Prohibition of Chemical Weapons (OPCW).  On 23 June 2014, the last declared chemical weapons were shipped out of Syria for destruction.  The destruction of the most dangerous chemical weapons was performed at sea aboard the "Cape Ray", a vessel of the United States Maritime Administration's Ready Reserve Force, crewed with U.S. civilian merchant mariners.  The actual destruction operations, performed by a team of U.S. Army civilians and contractors, destroyed 600 metric tons of chemical agents in 42 days.  However, despite these efforts, the use of chemical weapons in Syria have continued to be reported, with the latest being the chemical attack on Khan Shaykhun in April 2017, which has been alleged to have been perpetrated by the Syrian government. Operation CHASE (an acronym for "Cut Holes And Sink 'Em") was a United States Department of Defense program for the disposal of unwanted munitions at sea from May 1964 until the early 1970s.  Munitions were loaded onto ships to be scuttled once they were at least 250 miles offshore.  While most of the sinkings involved conventional weapons, four of them involved chemical weapons.  The disposal site for the chemical weapons was a three-mile (five km) area of the Atlantic Ocean between the coast of the U.S. state of Florida and the Bahamas.  The CHASE program was preceded by the United States Army disposal of 8,000 tons of mustard and lewisite chemical warfare gas aboard the scuttled SS "William C. Ralston" in April 1958.  These ships were sunk by having Explosive Ordnance Demolition (EOD) teams open seacocks on the ship after they arrived at the disposal site.  The typical Liberty ship sank about three hours after the seacocks were opened. The Rocky Mountain Arsenal National Wildlife Refuge is a 15988 acres National Wildlife Refuge located adjacent to Commerce City, Colorado, in the United States.  It is approximately 8 mi northeast of downtown Denver.  The facility is on the grounds of the former Rocky Mountain Arsenal, a United States Army chemical weapons manufacturing facility.  The site was designated a national wildlife refuge in 1992 by the United States Congress, and underwent a costly environmental cleanup in order to remove pollutants.  The refuge is managed by the United States Fish and Wildlife Service.  More than 330 species of wildlife inhabit the refuge, including raptors, deer, raccoons, coyotes, white pelicans, black-footed ferrets, black-tailed prairie dogs, and bison. Basin F was constructed by the United States Army in 1956 at the Rocky Mountain Arsenal, to provide for the disposal of contaminated liquid wastes from the chemical manufacturing operations of the Army and its lessee Shell Chemical Company.
