Cañon City community members will meet again with Cotter Corp. on Thursday to hear about the former uranium mining company’s pilot groundwater cleanup project.
Cotter hopes the project will reduce uranium and molybdenum contaminates to safe levels, but so far, community members have had mixed feelings about the effectiveness of the program.
Doni Angell, a member of the Lincoln Park Community Advisory Group that hosts the meetings and frequently comments on Cotter projects, said the proposed project, known as the Organic Bioreactor Work Plan, will only create a more concentrated toxic environment…
The project proposes an organic method using wet hardwood mulch to remove contaminates from the groundwater, rather than synthetic chemicals that most uranium mills use. The mulch, Cotter believes, would remove oxygen from water flow areas, causing the uranium to separate from the water. Because the water is migrating down slope through the mulch, Cotter anticipates successful contamination reduction using the natural aquifer as opposed to a mechanically propelled system.
“This is the simpler solution based on our tests, and sometimes the simple solution is the better solution,” Cotter project manager Steve Cohen said, adding that capital costs for this type of project are much lower than synthetic chemical-based ones.
Community Advisory Group member Carol Dunn said she does not know enough about the details of the project to make an assessment.
She said her hope going into Thursday relies on the relationship the community has developed with Cotter – a unique aspect of the Cotter/Lincoln Park site in relation to other Superfund sites where the responsible party is usually no longer present…
The project is in the informal public comment period, which was extended by the Colorado Department of Public Health and Environment from April 21 to May 7 last week after a request from the Community Advisory Group. The EPA and CDPHE – which oversees activities at the site because of its designation as a Superfund site in 1984 – are reviewing the details of the project and will provide comments following the May 7 comment deadline.
At that time, the agencies will also evaluate comments received from other agencies and the public, include the Community Advisory Group…
The original groundwater contamination in the Lincoln Park community was caused by the discharging of the uranium tailings into unlined tailing ponds. The ponds were closed in the early 1980s when the EPA listed the area as a Superfund site, and the waste was excavated and put into new lined ponds. The new ponds cut off most of the groundwater contamination, and, since then, the EPA has since declared the contaminated ground water status as “under control.”
The EPA is currently administering its 5-year review of the site to ensure that the site decision remedies are continuing to protect human health and the surrounding environment. The Community Advisory Group also has contributed to that project, providing the EPA with people to interview in the community about the impacts, or lack thereof, of the remaining contamination.
(The Community Advisory Group meeting will take place on Thursday at 6 p.m. in the Abbots Room at the Abbey Events Complex, 2951 East U.S. Highway 50. The meeting is open to the public.)
Colorado Department of Public Health officials on Friday received a report of a spill that occurred at the Cotter Crop. Uranium Mill south of here.
Steve Cohen, Cotter manager, reported the spill occurred just before 8:30 a.m. as Cotter workers were trying to drain a section of pipes that connect the new and the old pipeline. A new pipeline is being installed to prevent contaminated water escaping the site.
About 5,200 gallons of water was spilled, all of which was contained within the trench and Cotter workers were able to recover most of the spilled water using a water truck, said Warren Smith, health department spokesman.
It’s unclear how much “slightly contaminated” water seeped into the ground or will evaporate, but Steve Cohen, Cotter’s plant manager estimates around 3,000 to 4,000 gallons were picked up with the truck.
The spill happened when Cotter workers were attempting to drain a section of pipe where the old pipe and the new replaced pipe connect. A brittle or cracked valve is to blame, Cohen said. “Basically when the workers touched the valve it blew.”
The valve will be replaced, Cohen added.
The water was contained in the trench where pipeline construction has been ongoing for the last couple of weeks. Now, the water will return to the impoundment pond on Cotter property.
Cotter is replacing the pipeline after several leaks the last couple of years. Last August, Cotter reported a 7,000-gallon leak, which occurred over the course of 48 hours. That leak was the result of a hairline fracture in the pipleline — which is now being replaced on site.
Despite the most recent spill, Cohen said the pipeline replacement is still on track to finish the final week of March.
Cotter is required by Colorado law to report spills to the Colorado Department of Public Health and Environment, which posts the information on its website. CDPHE is expecting a report on the spill next week.
FromColoradoPolitics.com (Peter Marcus) via The Colorado Springs Gazette:
The man who led transition efforts for President Trump at the EPA said the administration’s proposed budget signals a commitment to abolish the agency.
But Myron Ebell, a Colorado College graduate and an outspoken climate change skeptic who leads energy and environment policy at the conservative Competitive Enterprise Institute, said it is not an overnight effort.
The administration’s preliminary 2018 budget proposal released Thursday charts a course that could lead to the end of the federal environmental agency, Ebell said, speaking to a conservative group at the libertarian-leaning Independence Institute in Denver on Thursday.
Ebell had proposed Trump make a 10 percent cut to the EPA in his first budget request. The proposal unveiled Thursday would cut the agency by significantly more, up to 31 percent. It represents about a $2.6 billion cut to the agency’s relatively small, when compared to other federal agencies, $8.2 billion budget.
The cuts would result in about 3,200 employees being laid off in the initial wave, which could include many regional staff. Denver is home to Region 8 headquarters, a multi-state jurisdiction that covers much of the Intermountain West, which employs about 500 people.
“I think there’s a serious commitment here to draining the swamp,” Ebell, calling upon a popular Trump campaign mantra, said to applause.
The preliminary budget request would eliminate as much as a fifth of the agency’s workforce, which stands at around 15,000. More than 50 programs would be eliminated, including energy grants that help to fight air pollution. Scientific research would also face massive cuts.
Environmental interests had feared Trump’s budget proposal would start to chip away at the EPA, ultimately leading to closure. News of the preliminary budget sent many into a tailspin, as it potentially signals a much faster outcome.
Trump also proposed a 12 percent cut to the Interior Department and a 5.6 percent cut to the Department of Energy.
“The president’s budget is a moral document, and President Trump has shown us exactly where he stands. These unprecedented cuts will hamper the ability of our park rangers, scientists, those who enforce the law against polluters, and other Coloradans from doing their important work,” said Jessica Goad, spokeswoman for Conservation Colorado.
“This is not just cutting the fat, this is a complete butchering of programs and jobs that are critical to Colorado.”
The move leaves specific uncertainty in Colorado, where the EPA has promised to cleanup toxic leaking mines that are spilling into the Animas River in Durango. The Gold King Mine spill in August 2015 was triggered by an EPA engineering error, causing about 3 million gallons of mustard yellow sludge to pour into the river.
In the aftermath of the spill, the EPA declared the area a Superfund site, which allows it to spend significant resources to implement a long-term water quality cleanup effort. Some worry those efforts would be diminished by reductions at the EPA.
But Ebell said a pushback to the EPA’s “regulatory rampage” does not mean that environmental controls would go away. He said regulations would still be enforced – especially on the state level – including around Superfund sites and clean drinking water.
“The question is, why do we need 15,000 people working for the EPA?” asked Ebell. “I understand why we need some … Maybe abolishing the agency is something that President Trump … would want to have a discussion about … I personally think it’s a good idea.”
Busting up the EPA is not a good idea, Myron.

On April 7, 2016, the Environmental Protection Agency proposed adding the “Bonita Peak Mining District” to the National Priorities List, making it eligible for Superfund. Forty-eight mine portals and tailings piles are “under consideration” to be included. The Gold King Mine will almost certainly be on the final list, as will the nearby American Tunnel. The Mayflower Mill #4 tailings repository, just outside Silverton, is another likely candidate, given that it appears to be leaching large quantities of metals into the Animas River. What Superfund will entail for the area beyond that, and when the actual cleanup will begin, remains unclear. Eric Baker
Cotter Corp. Uranium mill officials say a leak that dumped about 7,200 gallons of contaminated water on the mill property was caused by a rock that punctured a hole in a feeder line.
The feeder line connects to the main pumpback pipeline above a Soil Conservation Service dam that helps prevent rainwater runoff from leaving the mill site. The pipeline carries contaminated water that seeps past the earthen dam and returns it to an impoundment.
“When Cotter personnel excavated the area of the leak, a large rock was discovered above the feeder line. The rock had punctured the pipe, causing the leak,” said Stephen Cohen, Cotter Mill manager.
“Because the puncture and associated crack were small, only a relatively minor percentage of the total actually leaked. Most of the flow continued into the pumpback pipeline,” he explained.
Cotter maintains a pressure monitoring system on the pumpback pipeline that deactivates pumps in the event of a sudden, large pressure drop. However, the feeder is isolated from the main pressure monitoring system, Cohen said. The leak could have occurred on Saturday and continued for 48 hours until workers discovered it on Monday.
It is believed that none of the contaminated water seeped off the mill site, according to Warren Smith, a state health department spokesman.
Cotter officials are replacing the broken section of pipe and the feeder line should be reactivated today, Cohen said. The main pumpback system continues to operate, Smith said.
Because leaks formed in the main pipeline on two separate occasions late last year, Cotter and state health officials are working to finalize a proposal to build a new pipeline.
“Cotter’s original plan does not include replacing any feeder lines. Because this line has broken, however, company (officials) plan to replace this entire section of feeder line when they replace the main pipeline,” Smith said.
Federal and state health officials also are working with Cotter representatives to come up with a plan to clean up and decommission the now-defunct uranium mill site.
FromThe Pueblo Chieftain (Anthony A. Mestas and Tracy Harmon):
Pueblo County Commissioner Liane “Buffie” McFadyen is calling for sediment testing along the Arkansas River and at the bottom of Lake Pueblo to see if there is possible contamination from the now-closed Cotter Corp. Uranium Mill in Fremont County.
McFadyen said Tuesday during a press conference that she is concerned about the impact the possible “growing uranium and molybdenum plumes could have on Pueblo County.”
However, state health officials say the concerns are unfounded. But McFadyen remains concerned.
“This has been going on for 40 years and we can see that the situation is not getting any better and it’s time for us downstream from Canon City to take a stand,” McFadyen said, referring to the ongoing battle over the Cotter Mill cleanup.
Jeri Fry, director of the Colorado Citizens Against Toxic Waste Inc., shared the history of the Cotter controversy and presented maps from a 1987-89 study sowing ground uranium and molybdenum plumes that stretch from the Cotter Superfund site toward the Arkansas River.
“It’s likely that the molybdenum and the uranium plumes have grown since then. We just want answers,” McFadyen said. “And if the Arkansas isn’t contaminated, then that’s a very positive finding . . . We don’t find what we don’t look for.”
However, the concerns are unfounded, according to Colorado Department of Public Health Public Information Officer Warren Smith and Cotter Corp. Mill Manager Steve Cohen. They agree that Arkansas River water is not impacted by contamination from the Cotter mill.
“The Arkansas River is sampled routinely and the results have been showing that the river water quality has not been impacted,” Smith said.
“We constantly collect samples and data every quarter and there is no evidence that Cotter has impacted the Arkansas River.”
Both state and federal health officials study the data and “nobody has ever found anything to suggest that,” said Cohen.
“I am personally disgusted that the Pueblo County commissioners would have a meeting about this and not invite us to speak on the topic,” Cohen said.
And Jennifer Opila, Colorado Department of Public Health site director, said:
“I understand that the sediment has not been sampled (since 2004), but without impact on the water quality, there is no information that would lead us to believe the sediment would be contaminated. There is no contamination of the Arkansas River near the Cotter site, so Pueblo Reservoir would not be impacted.”
“This issue and all other potential issues will be looked at as part of the remedial investigation as we work toward final cleanup,” she said.
McFadyen said she is aware of water testing, but is calling for sediment testing and if it is positive, “Cotter should pay to treat it.”
McFadyen said in 1986, the USGS suggested on behalf of the federal government that sediment and not only the water be tested in the Pueblo reservoir.
“With the plume growing toward the Arkansas River, it’s time. It’s time to take action,” McFadyen said.
She said the possible contamination also could affect Colorado Springs because of the Southern Delivery System, which pipes water from Lake Pueblo up to that community.
State health officials overseeing the Cotter Corp. mill have not felt the study of Minnequa and Pueblo reservoir water quality pertinent since 2004.
“A 2004 review of water quality of the (Minnequa and Pueblo) reservoirs as well as the Arkansas River and associated drainages concluded that they are not impacted by the mill contaminants,” Smith said.
Part of the reason that the downstream reservoirs have not been tested since 2004 is due to the absence of high levels of radium-226, thoium-230, molybdenum and nickel in bodies of water much closer to the mill.
“Sediment sampling in Sand Creek (just north of the mill site), the Arkansas River and the Fremont Ditch indicate that constituents of concern are similar to (natural) background data. These locations are closer to the mill than the Pueblo reservoir and the Minnequa Reservoir,” the state health review concluded.
While the legacy contamination is still present in Lincoln Park groundwater plume (though declining), remedial measures have been effective in preventing public exposure to the Lincoln Park plume. A 2008 water use survey concluded that only one Lincoln Park water well exceeded a drinking water standard for contamination.
The Agency for Toxic Substances and Disease Registry draft public health assessment in 2010, conducted at the request of Colorado Citizen’s Against Toxic Waste, found that Cotter contamination did not present a current threat to human health or the environment, according to state health documentation.
“We need to understand all of the materials and how they are moving through the groundwater and how after these 30-40 years they have reached the river and if they are moving on downstream,” Fry said.
“That is a terrible trick to play on our neighbors. When you see a barn burning, do you go tell the authorities or do you just turn your head? And I am telling the authorities. Let’s all band together and get this tested.”
“This site is leaking into the neighboring community and it has contaminated the wells and it is a slow moving problem and because of that, people aren’t aware of it,” Fry said.
Fry is calling for more testing of water near the site and they’re looking for help from the community.
“Until we know where it is, we can’t realistically, effectively clean it up,” she said.
She fears the waste may have spread downstream through the Arkansas River and to the Pueblo Reservoir, which has caught the attention of Pueblo County Commissioner Buffie McFadyen.
“I do believe it’s time for Pueblo to get involved and work with the citizens of Fremont County to not only demand a remediation plan that’s realistic to cleanup the site, but also to demand testing along the Arkansas in the sediment and in Pueblo Reservoir,” she said.
McFadyen, now also demanding more testing of the sediment specifically.
And the possibility of tainted water is unsettling to some locals in Pueblo.
“This water comes from the same area, I imagine it passes through, so it’s picking up stuff definitely,” Patricia Hitchcock, a Pueblo resident said.
While others say, this isn’t anything to worry about just yet.
“I think there’s always a little bit of concern about stuff in the water, it wouldn’t keep me out unless it was really serious, but a little bit of concern. In 10 years, I haven’t gotten sick once from the water,” Daniel Rottinghaus, a Pueblo kayaker said.
Cotter officials tell News5 these claims of contamination in the Arkansas River are simply not true and that they routinely test the water and sediment.
From the Colorado Springs Independent (Pam Zubeck):
Tuesday morning, Colorado Citizens Against Toxic Waste gave a presentation to commissioners about their suspicions that the toxic substances have leaked into Pueblo Reservoir.
Why should we in Colorado Springs care? Because one source of water for Colorado Springs and Fountain is the Pueblo Reservoir, via the Fountain Valley Authority line and the Southern Delivery System pipeline.
Commissioner Liane “Buffie” McFadyen is, Pueblo County Commissioner is overseeing efforts to learn more about the situation.
After two recent breaks in the Cotter Corp. Uranium Mill’s pumpback pipeline which returns contaminated water to an impoundment, officials on Friday outlined a plan to replace 3,500 feet of the pipeline.
Cotter officials reported two leaks occurring at the end of November and in early December in a pipeline that captures contaminated water that seeps past an earthen dam on Cotter Corp. Uranium Mill. It appears that both times the leaks were contained to Cotter property, according to Warren Smith of the Colorado Department of Public Health.
The Cotter Corp. reported a water spill at their site [November 26, 2015] to the Colorado Department of Public Health and Environment, the CDPHE said.
“(Cotter) discovered a spill of approximately 1,800 gallons of water at the pumpback line immediately upstream of the SCS dam on Cotter property,” a CDPHE email states. “They believe that the spill occurred overnight or early that morning. All water was drained back to the sump and no standing water was left on the ground. The leak has been repaired and the pumps have been turned back on.”
The CDPHE stated this incident is currently under investigation, but they believe water did not go beyond the property.
“A multi-part containment system keeps surface water and groundwater on Cotter property from entering Lincoln Park,” the email stated. “System features include a compacted clay barrier extending to non-porous shale on the upstream side of the Soil Conservation Service Dam, a water collection pipe and three pumps. An underground cutoff wall downstream adds another layer of protection.”
Meanwhile there was another spill yesterday, December 3, 2015. Here’s a report from Sarah Rose writing for The Canon City Daily Record. Here’s an excerpt:
Thursday morning Cotter employees discovered that the pumping system shut down, CDPHE said.
“Cotter personnel then inspected the SCS pumpback line and found the location of the break,” a CDPHE email stated. “Based on the amount of time between the morning inspection and observing the 10 a.m. shutdown, Cotter estimates that approximately 500 gallons of water leaked from the pipe line. Leaked water flowed approximately 20 feet, ponded in a slight depression and infiltrated into the soil. It appears that the water stayed on Cotter property.”
