The U.S. Army is applying for a Class 2 permit modification to Rocky Mountain Arsenal’s Basin F Post-Closure Plan. For info, see CDPHE and below:
This is a public notice that the U.S. Army is applying for a Class 2 permit modification to the Basin F Post-Closure at Rocky Mountain Arsenal.
Public comment period: April 27, 2023 through May 26, 2023
Written comments should be directed to Susan Newton, Project Manager CDPHE HMWMD 4300 Cherry Creek Drive South, Denver, CO 80246 (susan dot newton at state dot co dot us).
The draft hazardous waste permit modification and supporting documents are available for review on our website: https://cdphe.colorado.gov/HMWMD-public-notices
** A public meeting to discuss this permit modification request may be scheduled upon citizen inquiry or request for a meeting.
Inquiries regarding this facility should be directed to:
Venissa Ledesma, CDPHE, Marketing and Communications Specialist at 303-692-3432 or venissa dot ledesma at state dot co dot us
or
Patty Lee, U.S Army at 303-298-0300 or patty dot l dot lee6 at civ dot mail dot mil.
The permittee’s compliance history during the life of the post-closure plan is available from Ms. Susan Newton of the Colorado Department of Public Health and Environment.
The U.S. Army manages the Rocky Mountain Arsenal Basin F Former Surface Impoundment and former Basin F Wastepile, collectively referred to as Basin F, that contains hazardous waste from the former Rocky Mountain Arsenal site. Basin F is currently managed under a Post-Closure Plan that was approved by the Colorado Department of Public Health and Environment on July 2, 2009.
The U.S. Army is applying for the following Class 2 permit modification to the Rocky Mountain Arsenal Basin F Post-Closure Plan Rev. 2, April 10, 2023.
This modification includes updates to the inspection and sampling frequencies for the Basin F Cover that are based upon best management practices developed from experience gained over 10 years of managing the site. This proposed modification also includes numerous editorial updates.
Procedures for reaching a final decision:
The public is obligated to raise all reasonably ascertainable issues regarding any condition in the draft permit modification during the public comment period as required by 6 CCR 1007-3, Section 100.509. In accordance with 6 CCR 1007-3, Section 100.61, only those portions of the permit subject to the modification are reopened for public comment. FAILURE TO RAISE AN ISSUE OR PROVIDE INFORMATION DURING THE PUBLIC COMMENT PERIOD MAY PREVENT YOU FROM RAISING THAT ISSUE OR SUBMITTING SUCH INFORMATION IN AN APPEAL OF THE DEPARTMENT’S FINAL DECISION. ONLY MATTERS RAISED DURING THE PUBLIC COMMENT PERIOD MAY BE CONTESTED IN ANY APPEAL OF THE PERMIT (SECTION 6 CCR 1007-3, SECTION 100.506 (D)(1)(VI)).
The Division will consider all comments on the draft permit prior to making a final decision on it. Following the public comment period, the Division will issue a final decision and a response to comments in accordance with 6 CCR 1007-3, Sections 100.511-512.
CDPHE v U.S Army (Again)
Big surprise.
The Colorado Department of Public Health and the Environment’s (CDPHE) Hazardous Materials and Waste Management Division filed a lawsuit in U.S. District Court in April to compel the U.S. Army to comply with standards set by Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), commonly known as Superfund. There are “four claims for relief” that range from lack of dewatering of the Shell Trenches to demanding the Army provide a plan concerning surface water standards for former Basin E.

Deep-Well Injection
A newish CRS report titles Human-Induced Earthquakes from Deep-Well Injection briefly discusses the Army Chemical Corps decision to dispose of its wastes through deep-well injection. The CRS report describes the process, that lead to
an M 4.8 earthquake that struck northeast Denver, on August 9, 1967 was generally accepted as the largest recorded human-induced earthquake in the United States. The M 4.8 earthquake was part of a series of earthquakes that began within several months of the 1961 start of deep-well injection of hazardous chemicals produced at the Rocky Mountain Arsenal defense plant. The earthquakes continued after injection ceased in February 1966.21 The disposal well was drilled through the flat-lying sedimentary rocks into the underlying older crystalline rocks more than 12,000 feet deep, and injection rates varied from 2 million gallons per month to as much as 5.5 million gallons per month.
For additional background, see the original report on deep-well injection (posted below) and of course, that historical treasure, The Blue Book.
The Devil’s Bargain
I recently came across this short film titled The Devil’s Bargain created by students whose school is in proximity to RMA:
The National Contingency Plan
Confusing letters between the RMA Subcommittee and the EPA on 10 x -6 risk and Superfund.
Readers are advised to scan over 40 CFR 300 before reading our letters; our assumption was that cleanup standards/cancer risk for RMA would follow 10 x -6 as outlined in the National Contingency Plan, not 10 x -4 as applied to the Arsenal and in many CERCLA cleanups.
first letter | EPA response | SC response…then we gave up.

It is my understanding the original intent of the CAMU was to provide a framework for the development and use of alternative and innovative technologies by allowing flexibility in the Resource Conservation and Recovery Act (RCRA) Land Disposal Rule (LDRs). But at one time, the use of CAMU subverted the LDRs rule by allowing untreated dioxin laden waste landfilled without treatment. This capricious misapplication of the rule is contrary to the law, and was not the intent of Congress, the EPA and the Colorado Hazardous Waste Commission which promulgated LDRs.

RMA & Shell Oil
Perhaps the most controversial party to RMA cleanup, on April 30, 1952, Shell Oil purchased Julius Hyman & Company, which manufactured “high-potency insecticides.” Hyman officially became integrated into Shell on January 1, 1955 [see Kendall Beaton’s Enterprise in Oil: A History of Shell in the United States, Appleton-Century-Crofts, 1957].

The Puzzling Case of the NSCMP and RMA
In 2000, a press release was drafted from us gals in Sierra Club and the Chem Weapons Working Group (CWWG ) asking the Army to consider alternate means of disposing of sarin bomblets. At the time, the Army was using open detonate “technology” for dealing with potentially unstable materiel, setting off the bomblets in the Arsenal acreage. While we understood the volatility of these weapons and urgency of disposal, open air detontation of Sarin bomblets compromised air quality, public health, and the safety of neighborhoods surrounding RMA.
After much discussion between Colorado Department of Health and Environment (CDPHE), Army, and the U.S. Army Chemical Materials Agency’s Non-Stockpile Chemical Materiel Project (NSCMP), the Explosive Device System (EDS) was brought to the Arsenal from its testbed in Porton Down, UK, as an alternative technology to replace open detonation of bomblets and crude air and weather monitoring.
A huge part of the EDS story involves the NSCMP in providing me with an on the ground education in understanding programmatic authority and other issues involved in using the EDS at RMA. Below are behind the scenes conversations between the CDPHE and myself about the bomblets, NSCMP authority, and the EDS:
my original email | CDPHE response EDS | additional EDS discussion
Also relevant to the EDS discussion is the NSCMP’s Survey and Analysis Report, (2nd ed.); note the section on the Arsenal, but yet the NSCMP’s role was relegated to observer status in Arsenal cleanup. This was of constant amazement (and consternation) to many citizens who served on the Arsenal’s Restoration Advisory Board and the Site Specific Advisory Board. The existence of this report – issued BEFORE the Arsenal’s Record of Decision – would have influenced a better informed cleanup and indeed strengthened the programmatic authority of the NSCMP in working on other nonstockpile sites throughout the country. The history of NSCMP participation on former chem weapons sites remains compelling case study into (I think) DoD, and specifically, Army culture.
