Sand Creek: So far Suncor Energy has not been able to stanch the flow of polluted groundwater
May 2, 2012
From The Denver Post (Bruce Finley):
Neither state regulators nor Suncor has calculated how much cancer-causing benzene and other contaminants have entered the waterways from an underground plume spreading from the refinery under the adjacent Metro Wastewater Treatment Plant. But interceptor trenches, vapor-extraction systems and recovery wells over the past five months have removed about 697,200 gallons of material from the ground, Suncor officials said Tuesday in a response to Denver Post queries.
A fountain aeration system designed to separate benzene from water, before the creek reaches the river, has been shut down. Colorado Department of Public Health and Environment regulators ordered the shutdown April 24. Health department spokesman Warren Smith said this was done to evaluate the effectiveness of Suncor’s underground walls and extraction systems installed on Metro Wastewater property near Sand Creek. Smith acknowledged “fluctuations” in benzene levels in the creek and river but disputed any overall upward trend…
“We believe that the permanent solutions being installed and operated — trenching systems and treatment systems on both Suncor and Metro’s property — will effectively isolate and manage the plume and dramatically lower the dissolved benzene level in Sand Creek,” company vice president John Gallagher said in a prepared response. The latest water-test data show benzene levels at 400 parts per billion or higher in the South Platte and at two monitoring wells along Sand Creek. The federal drinking-water standard for benzene is 5 ppb. At the South Platte location (about 50 feet downriver from the confluence with Sand Creek), the 400 ppb detected April 25 was more than double the 180 ppb recorded April 6 and 73 percent higher than the 230 ppb recorded Dec. 2 — when EPA overseers launched an emergency response. Three monitoring sites along Sand Creek were tested April 2-4 and again April 9. During that period, benzene levels at the sites increased — to 150 ppb from 12 ppb; to 490 ppb from 89 ppb; and then to 510 ppb from 73 ppb. On April 25, the two sites nearest the creek bank, where black goo began oozing into the creek in November, still showed benzene concentrations of 410 ppb and 450 ppb.

2012 Colorado legislation: HB12-1161′Nutrients Scientific Advisory Bd Water Quality’ would suspend nutrient rules from the CWQCC
April 24, 2012
From The Pueblo Chieftain (Chris Woodka):
…the Pueblo Board of Water Works broke ranks with the Colorado Water Congress and the city of Pueblo Tuesday and voted 5-0 to oppose HB1161. The bill has cleared committee and is awaiting action by the state House of Representatives. The bill would suspend rules adopted by the Colorado Water Quality Control Commission last month for review by the legislative Water Resources Committee later this year. A recommendation to the commission would be made by Nov. 1…
The Colorado Water Congress represents broad interests, many of which operate both drinking water and wastewater systems, explained Paul Fanning, legislative liaison for the water board. “It’s cheaper for drinking water providers to treat it than for dischargers,” he told the board.
Using political means to answer scientific questions could risk federal Environmental Protection Agency intervention in Colorado water quality regulations, Fanning said.
Brush: New wastewater treatment plant online
April 18, 2012
From the Brush News Tribune (Katie Collins):
The project also is one of the most ambitious that the city has seen in years and as of exactly 10:20 a.m. on April 12, Brush’s newest state-of-the-art wastewater treatment plant is up and running, ready for all the dirtiest business that Brush can dish its way.
On hand to get the facility rolling were Brush Mayor Dan Scalise who, along with City Administrator Monty Torres and Wastewater Manger and City of Brush Director of Utilities Dale Colerick, opened the plant in official fashion that morning as Scalise ceremoniously turned the valve to allow wastewater to flow into the facility.
As of the opening ceremony, just 50 percent of the newest portion of the plant is seeing use as a few more processes are in need of completion, including the building of one more settling tank, completion of the UV filtering system, as well as additional fencing, seeding, grating and solids handling assembly…On March 12, 2012, in fact, the Colorado Water Quality Control Commission opened hearings on proposed water quality standards for nutrient concentrations in the state’s rivers and lakes as well as limits on anyone who discharges into those waters. Limits were adopted and will be implemented over the next 10 years and the City of Brush’s newest plant was designed specifically to utilize new technologies in order to remove nutrients such as phosphorous and nitrates from the City’s discharge to the South Platte River.
Environmental Working Group: The drinking water used by millions of Americans is contaminated!
April 12, 2012
Colorado is debating new standards for nitrogen and phosphorus in wastewater streams to reduce nutrients in surface water ahead of a federal mandate.
Here’s a research paper on the problem from the Environmental Working Group (Olga V. Naidenko/Craig Cox/Nils Bruzelius). Here’s the executive summary:
Water that runs off fields treated with chemical fertilizers and manure is loaded with nitrogen and phosphorus, two potent pollutants that inevitably end up in rivers and lakes and set off a cascade of harmful consequences, contaminating the drinking water used by millions of Americans. Treating this water after the fact to clean up the contamination is increasingly expensive, difficult and, if current trends continue, ultimately unsustainable. The only solution that will preserve the clean, healthy and tasty drinking water that people expect is to tackle the problem at the source. This paper explains why.
Nitrate, the most common form of nitrogen in surface and groundwater, is directly toxic to human health. Infants who drink water with high nitrate levels can develop an acute, life-threatening blood disorder called blue baby syndrome. high nitrate levels in water can also affect thyroid function in adults and increase the risk of thyroid cancer.
Phosphorus stimulates explosive blooms of aquatic algae, including the especially dangerous cyanobacteria (blue-green algae) that produce toxins that can be deadly to pets, livestock, wildlife – and people. Toxins pro- duced by cyanobacteria can harm the nervous system, cause stomach and intestinal illness and kidney disease, trigger allergic responses and damage the liver. Even after a brief exposure, cyanobacterial toxins can cause skin rashes, eye irritation and breathing problems.
The cascade continues when utilities try to combat these and other threats by treating drinking water with chemical disinfectants such as chlorine. Treating algal contamination this way gives rise to carcinogenic disinfection byproducts, whose levels typically spike during the summer months – when algae blooms peak. Commonly used measures to reduce algal contamination add hundreds of thousands of dollars annually to water utilities’ treatment costs. Algae can also give tap water an unpleasant taste and smell, a recurrent annoyance for agricultural areas and the water utilities that serve them.
This report focused on four states in the core of the Midwestern corn belt – Illinois, Iowa, Minnesota and Wisconsin. Nutrient overload in surface and groundwater is a significant water quality problem for these states, making nitrate and phosphorus levels higher and algal blooms more frequent compared to national averages.
To tackle polluted source water, water utilities in the region are often forced to install expensive treatment plants that can cost millions to install and operate. USDA economists estimate that removing nitrate alone from drinking water costs more than $4.8 billion a year. The cost of dealing with algal blooms is particularly daunting. The total capital cost of water treatment that would address cyanobacterial blooms and cyanotoxins, can range between $12 million and $56 million for a town of 100,000 people.
The only true solution is to confront the issue upstream, at the point where pollution – much of it from farms – first flows into America’s precious surface water and groundwater. This year’s debate over renewing the federal farm bill is a referendum on America’s commitment to protecting our drinking water supplies at the source.
With the exception of large animal feeding operations, farm businesses are exempt from the pollution control requirements of the federal Clean Water Act, and few states have authority to compel farm businesses to adopt practices that reduce the amount of farm pollution reaching our rivers, lakes and bays. As a result, the farm bill, which is renewed every five years, serves as the primary tool for addressing the environmental damage caused by polluted runoff from agricultural operations.
Congress should take three steps to ensure the new farm bill protects drinking water:
· Reform Farm Subsidies – Congress should end direct payments, reduce subsidies for farm insurance programs and refuse to create new farm entitlement programs that encourage all-out production to the detriment of the environment. Instead, lawmakers should help farmers when they suffer deep losses in yields and provide options for them to purchase additional crop and revenue insurance at their own expense.
· Renew the Conservation Compact — Congress should renew the “conservation compliance” provisions of the 1985 farm bill by relinking wetland and soil protection requirements to crop insurance programs. In addition, legislators should require farm businesses that receive subsidies to update their conservation plans and should strengthen the government’s enforcement tools.
· Strengthen Conservation Incentive Programs – Congress should strengthen programs that reward farmers who take steps to protect sources of drinking water. In addition to providing adequate fund- ing, Congress should expand “collaborative conservation” tools that award funds to groups of farmers working together to protect drinking water sources. Greater focus should be placed on restoring buffers and wetlands that filter runoff of farm pollutants.
Meanwhile, here’s a analysis closer to home from Dan Randolph running in The Durango Herald. From the article:
In 2002, the Animas River through Durango experienced algae blooms, and with the possibility of low water levels again this year, the risk is again on some of our minds. Right now, the Animas River in New Mexico, from the state line down to Farmington, where it joins with the San Juan, is out of compliance with New Mexico’s nutrient standards. This is not a theoretical issue…
For a decade, the Colorado Water Quality Control Commission and hundreds of stakeholders from throughout the state have wrestled with developing nutrient standards for Colorado’s rivers and streams. In March, the commission preliminarily adopted a two-pronged approach to nutrients that reflects Colorado’s needs and abilities. The proposed rules recognize that meeting new standards will take both time and flexibility. The rules include a generous implementation timeline for wastewater treatment plants to upgrade their systems, and voluntary programs for farmers and ranchers.
The system the Water Quality Control Commission has set out will be refined to meet the individual needs of each stream or river during the regular review of water-quality standards done for metals and other pollutants, and treatment-plant reviews. Known as the triennial review process, each of Colorado’s nine river basins is studied in turn, and standards are determined. Under the new rules, these standards will now also include nutrients. The San Juan, Dolores and Gunnison basins will undergo this review process later this year.
Becky Long: ‘Phosphorus and nitrogen are incredibly prevalent…we’ve ignored it for 20 years’
March 23, 2012
From the Summit County Citizens Voice (Bob Berwyn):
“Phosphorus and nitrogen are incredibly prevalent. They’re in animal waste, human waste, fertilizer, and we’ve ignored it for 20 years,” said Becky Long, water caucus coordinator for the Colorado Environmental Coalition. If left unaddressed the pollution causes algae blooms and dead zones in waterways, impacting aquatic wildlife and Colorado’s outdoor recreation opportunities. Long said she’s encouraged by the Colorado Water Quality Control Commission’s early support for the new standards limiting nitrogen and phosphorus pollution. The rule is still subject to challenge at subsequent hearings, as well EPA review and final approval. Long said the standards go beyond simply protecting aquatic life and human health by addressing potential impacts to recreation…
Phosphorus has been identified as a potential problem in Cherry Creek reservoir. In the high country, effluents from Grand County have affected water quality in Grand Lake. The two pollutants are a problem anywhere there’s a lot of effluent going back to the stream, for example downstream of the metro wastewater treatment facilities east of Denver, Long said, explaining that the new rules are forward looking and will protect water quality for the next 50 years, as the state’s population grows by up to 5 million.
While she expects some challenges from agricultural stakeholders and perhaps some municipalities, Long said the rules are written with built-in flexibility and can be implemented in phases, as waste water treatment plants plan for future upgrades. State water quality regulators were responsive to small- and mid-sized communities as they crafted the rule, she said.
Finally, it’s important to remember that the pollution generated in Colorado have impacts far beyond the borders of the state. Addressing the issue of nutrients here helps tackle the serious issue of the dead zone in the Gulf of Mexico, Long said. “We need to own the fact that this is us causing the problem. It’s not Mr. Burns, it’s us, every time we flush the toilet. If we don’t pass the state rule, we could meet the same fate as Florida. The EPA will write a rule that’s a lot more stringent and we’ll lose our chance to do this at the state level,” she said.
Colorado adopts new standards for phosphorus and nitrogen in wastewater treatment plant releases ahead of anticipated EPA rules
March 17, 2012
From NBCNews11.com (Andie Adams):
The Colorado Water Quality Control Commission has given preliminary approval to regulations that would limit the amount of nitrogen and phosphorus in bodies of water statewide.
“When you get too many nutrients in a water body, then it can make algae bloom more, then when that dies, it robs the stream of oxygen. So you can have problems for fish and aquatic organisms,” said Hannah Holm, coordinator of CMU’s Water Center…
“Some people are making the argument that it’s not clear that nutrients are really a major environmental and water quality problem here in the Grand Valley,” said [Hannah Holm, coordinator of CMU's Water Center].
But water director Jennifer Bock with the High country citizen’s alliance said for this area, the regulations would be preventative. “We’ve seen bad algae on the Front Range and we want to protect the west slope so this is just a good first step to get ahead of the problem,” said Bock.
The rules are broken down into two sets. The first would require large wastewater treatment plants, like Grand Junction’s Persigo plant, to control their nitrogen and phosphorus levels. “Those guys will be affected in the next couple of years. Their permits will come up and they’ll work with the state to see what they need to do to come in with compliance,” said Bock.
The second set would require that all bodies of water comply with the nutrient amounts by 2024. That includes drainage authorities and districts. “We have to monitor this and make sure the quality is what these regulations require it’s going to cost a lot of money to do that,” said Kevin Williams, manager for the Grand Valley Drainage District.
He said he is worried that these regulations will become an unfunded mandate. “A benefit analysis that was done is that right now in this first phase, this is going to encumber the people of the state of Colorado almost $2.5 billion, and it’s unfunded. In other words, the state isn’t helping us out,” Williams.
From The Grand Junction Daily Sentinel (Charles Ashby) via Google Groups:
After nearly three days of public testimony and several more hours of deliberation, the nine-member commission gave its initial approval late Wednesday of more than 600 pages of new regulations that are designed to limit how much nitrogen and phosphorus can be in the state’s rivers and streams.
The final regulations will be reviewed again in May, with the new regulations going into effect June 30, said Steve Gunderson, executive director of the Colorado Water Quality Control Division. “The commission gave preliminary approval to much of the water control division’s final proposal regarding nutrients management,” Gunderson said. “The only major substantive difference is relaxation of the total inorganic limitation for existing facilities from 10 milligrams a liter to 15 milligrams.”
He said the new rules will impact only the largest wastewater treatment plants in the state, which account for 10 percent of all plants. Those 44 plants include the Persigo Wastewater Treatment Plant in Grand Junction. Wastewater treatment plant officials statewide, who opposed the new regulations, said it could cost them up to $2 billion in new equipment, saying those costs will be borne by ratepayers. Persigo officials estimated their new costs at upwards to $24 million.
Gunderson, who calls high nutrient levels one of the biggest water-quality challenges facing the nation, said the limits are designed to protect the state’s waterways from too much algae. High algae levels can create oxygen-dead zones that can kill plants and aquatic life.

Colorado is proposing new nutrient standards for nitrogen and phosphorus in wastewater streams
February 28, 2012
I missed this opinion piece in favor of tougher nutrient standards from Ross Vincent and Seve Glazer that is running in The Pueblo Chieftain. It was part of a point/counterpoint that the Chieftain ran on Sunday. Here’s my original post. Thanks to Desmid for the heads up in the comments for the post. Here’s an excerpt from the article I missed:
…imagine our disappointment at learning that the city of Pueblo has joined forces with some other municipal dischargers in attempting to weaken new clean water protections proposed by the state health department. The issue in this case is nutrients — predominantly chemicals containing nitrogen and phosphorus. These nutrients are commonly found in lawn and agricultural fertilizers, in some commercial products (such as cleaners), in some industrial discharges, and in human and animal excrement. They find their way into our streams and lakes primarily in urban, suburban, and industrial discharges, and in urban and agricultural runoff. Here on the Front Range, the biggest sources are municipal sewage and stormwater discharges.
When nutrient pollution is allowed to accumulate in our lakes and rivers, it can harm aquatic life, sometimes causing fish kills. In drinking water, it can compromise human health because some nitrogen and phosphorus compounds are toxic and others can react with disinfectants used to kill bacteria in drinking water treatment facilities to form cancer-causing disinfection by-products. Levels of both nitrogen and phosphorus in parts of the Arkansas River basin are already more than 10 times higher than what should occur naturally, and we should expect those levels to get worse if Colorado’s Front Range population continues to grow as expected.
Some cities, like Pueblo, are arguing that the cost of reducing nitrogen and phosphorus levels in their discharges will be too high, that no one will want to pay for the necessary treatment, and that we should only address part of the problem — the phosphorus part — because only treating for phosphorus will be cheaper.
That is a stunningly shortsighted and ultimately self-defeating argument. It is eerily reminiscent of the complaints we sometimes hear from big industrial polluters when science reveals problems with pollutants in their discharges. If the state fails to act responsibly on both phosphorus and nitrogen pollution now, it is likely that the federal government will step in with more stringent requirements, with shorter fuses and even more costly solutions.
If the city’s arguments prevail, all the city will have succeeded in doing is to delay the inevitable. The nitrogen pollution problem will not go away. As ratepayers, we will be required to invest in phosphorus-only treatment now and then we will be hit again later with additional and duplicative improvements in our city’s wastewater treatment systems to deal with nitrogen.
The City of Pueblo supports the phosphorus-only alternative for proposed new nutrient standards for wastewater treatment plants
February 26, 2012
Here’s a guest column written by Gene Michael [wastewater director for the city of Pueblo] running in The Pueblo Chieftain. Click through and read the whole article. Here’s an excerpt:
The state’s original proposal, Regulation 31, would set stringent standards for phosphorus and nitrogen that would cost approximately $25 billion to implement statewide, according to a cost-benefit study conducted by the Colorado Water Resources and Power Development Authority.
An alternative, Regulation 85, would reduce the immediate cost to about $2.5 billion statewide by postponing the more stringent requirement for 10 years. In addition to cost considerations, there are flaws in the scientific methods used to develop the proposed standards that are too complex to discuss here.
Either of these alternatives would require a greater level of wastewater treatment than Pueblo’s water reclamation facility can provide. It will be necessary to raise wastewater rates to comply.
Pueblo supports the third alternative, which sets standards for phosphorus only. The phosphorus-only alternative would cost only about $521 million statewide, because removing nitrogen to low levels is much more costly than removing phosphorus. We know it will work because Colorado has successfully used phosphorus-only controls to protect large lakes and drinking water reservoirs, including Lake Dillon, Chatfield Reservoir, and Cherry Creek Reservoir for more than 20 years. Pueblo’s water reclamation facility will be able to meet a phosphorus-only limit without taking on more debt for construction of new facilities.
Pueblo and the United States in general have a split personality when it comes to water quality. On one hand, everyone knows we need and want clean water. On the other hand, nobody wants to pay. And therein lies the issue. The living cells of your body produce waste products that the body has to eliminate. And when we do, the materials we flush away are rich in phosphorus and nitrogen. With nutrients, you cause the issue, and you have to pay for it.
Proposed new state nitrogen and phosphorus standards for wastewater plants are under attack
January 22, 2012
Here’s a report from Barbara Cotter writing for The Colorado Springs Independent. Click through and read the whole article. Here’s an excerpt:
The proposed regulations are meant to address a stronger nationwide push from the Environmental Protection Agency to cut the amount of nitrogen and phosphorus discharged from wastewater treatment plants into rivers, streams, lakes and reservoirs. But opponents question the science used to support the need for the regulations, and warn that water bills could double or even triple for some Colorado ratepayers if municipalities are forced to upgrade their facilities.
Earlier this month, the Pikes Peak Area Council of Governments sent a letter to Gov. John Hickenlooper urging him to block the proposed regulations. The same day, Republican state Sen. Steve King of Grand Junction introduced a bill that would essentially place a moratorium on the adoption of regulations.
“This action is not mandated by federal law, nor is it based on any demonstrated adverse environmental impacts occurring in Colorado waters from our facilities,” the PPACG wrote to Hickenlooper. “The cost of implementing such regulations on small and medium-sized communities will be staggering, and we ask for your intervention to stop this regulatory mandate.
Steve Gunderson, director of the Water Quality Control Division at the Colorado Department of Public Health and Environment, defends the science, but acknowledges that compliance could be costly. However, he notes, only about 30 percent of wastewater plants in Colorado would be affected by the regulations, which are, at the outset, more lenient than what some environmentalists might consider ideal.
Mostly, he says, the state needs to act before the EPA steps in. “We continue to believe that is to Colorado’s benefit to start addressing the nutrients so it’s not forced on us by means of a lawsuit of the EPA dictating to us what needs to be done,” Gunderson says…
To [Tad Foster, a Colorado Springs environmental attorney specializing in water quality issues], the site-specific approach is ideal, but given the reality of the situation, he and the Colorado Nutrient Coalition are proposing that limits be imposed on phosphorus, not nitrogen, at least for the time being. “Why? Because the cost of doing total nitrogen is six times the cost of doing total phosphorus,” Foster says.
He estimates the cost to wastewater plants to control just phosphorus would be $635 million, compared with $2.46 billion to regulate both nitrogen and phosphorus. And that’s just to meet less restrictive standards. To go whole-hog with the “ultimate set” of restrictions for nitrogen and phosphorus would, according to varying estimates, cost from $20 billion to $25 billion.
Gunderson says the state is proposing regulations on both nitrogen and phosphorus for a reason. “Our science, and what we assert, is, you really have to address both of them,” he says. “If you address one and not the other, you’re not going to see a lot of progress. They’re both fertilizers; if you put nitrogen on your lawn and not phosphorous, your lawn will still turn green.”
But the proposed regulations do not impose the most restrictive limits, he says. “It starts knocking it down. We’re trying to find a way to start putting a dent in this thing,” Gunderson says…
Still, there’s fear among many communities that they’ll be socked with a massive bill. Like the PPACG, the Colorado Rural Community Coalition wrote a letter to Hickenlooper that was signed by 12 wastewater dischargers in El Paso County, expressing concern about the regulations. Gunderson says that about half of the opponents who have signed letters wouldn’t be affected by the current proposal.
Gunderson understands the opposition to the regulations, but says doing nothing is not an option. “I continue to believe that it makes sense to do this here, rather than having it forced upon us, which one day it will.”
From The Grand Junction Daily Sentinel (Charles Ashby):
Officials with the Colorado Water Quality Control Division say the new rules are needed to prevent even stricter ones from being imposed on the state by the federal government. At the same time, local wastewater experts say the proposed rules, known as Regulations 31 and 85, will do little to nothing to clean the state’s waterways. The issue centers on the amount of nutrients that end up in the state’s rivers and lakes. Having too many nutrients — nitrogen and phosphorus — causes algae to grow. That, in turn, saps oxygen from the water, creating so-called dead zones, places where nothing can grow and fish can live, said Steve Gunderson, executive director of the water division.
While the U.S. Environmental Protection Agency isn’t mandating what Colorado is considering, the federal agency ultimately will impose something even more stringent if the state doesn’t act on its own, he said. “The EPA has been pushing for states to do something for quite a few years,” Gunderson said. “It is one of the nation’s biggest water quality challenges. (The nutrients) causes a water body to get choked. It will rob the water body of oxygen, and it will raise the pH, the level of corrosivity, in the water. It can adversely impact aquatic life.”[...]
The division has filed about 600 pages worth of rules and other accompanying documents with the Colorado Water Quality Control Commission that call for lowering phosphorus and nitrogen levels to virtually zero over the next 10 years. The commission is holding a public hearing on the rules in the spring, with an expectation of having them go into effect by June 1…
Eileen List, industrial pretreatment supervisor for the Persigo Wastewater Treatment Plant in Grand Junction, said the city still is studying the proposed rules, but that it could cost as much as $24 million to comply with just with one portion of them. “When you get into Reg 85, there are impacts not just to wastewater facilities, but there are impacts to stormwater facilities as well as drinking water facilities,” List said. “This is where the city is still in the process of understanding the regulation.”[...]
So far, officials from 32 local entities have signed a letter complaining about the proposed rules, including the Clifton and Orchard Mesa sanitation districts, the Grand Valley Drainage District, the Battlement Mesa Metropolitan District and the towns of Rangely, Cedaredge, De Beque and Nucla. In the letter that is to be sent to Gov. John Hickenlooper by the end of the week, the officials say the regulations will cost all of them about $2 billion to be in compliance, and ask that he delay it until more scientific research can be done. “The state has not been able to show us that Colorado has a problem with nutrients,” said Michael Wicklund, manager of the Monument Sanitation District, who started the letter. “There is no funding from the state for any of this, or the federal government.”[...]
Eric Brown, the governor’s press secretary, said Hickenlooper will allow the public hearing process to run its course, and doesn’t plan to intercede.
Meanwhile, state Sen. Steve King, R-Grand Junction, said he plans to introduce a bill when the Legislature reconvenes next month calling for a five-year moratorium on the rule, to give local communities more time to study its impact. King said the proposed regulation is contrary to an executive order issued by the governor earlier this year to limit state regulations that prove too onerous while the state is recovering from the recession.

CWQCD’s proposed stricter wastewater treatment plant effluent standards for nitrogen and phosphorus will be costly

Local wastewater experts…say there’s no scientific evidence that shows all wastewater treatment plants are releasing too many nutrients, and have asked for more time to research the matter…

Gunnison River basin: CPDHE orders U.S. Energy Corp. to clean up water from the Mt. Emmons mine
January 14, 2011
From The Crested Butte News (Mark Reaman):
The first thing to know is that the town of Crested Butte drinking water is fine…
The state is demanding that U.S. Energy Corp, the company that ultimately owns the Mt. Emmons Project molybdenum mine, correct the situation immediately. U.S. Energy CEO Keith Larsen said the company is confident the situation will be rectified. “We can work through the issues. We want to have a face-to-face meeting with the state to talk about the things found in the report,” he said. “But the crux of the issue is, what is the obligation of a landowner to treat those waters that are contaminated with heavy metals that migrate onto your property during a heavy runoff?”
The state’s Water Quality Control Division of the Colorado Department of Public Health and Environment has given U.S. Energy until this week to respond to findings outlined by the department. An official “Compliance Advisory letter” was sent to U.S. Energy at the end of December. That letter “is intended to advise US Energy Corp. of possible violations of the Colorado Water Quality Control Act, its implementing regulations and permits, so that it may take appropriate steps to avoid or mitigate formal enforcement action.” The company must begin increased monitoring of the water immediately and “prepare a plan to reduce concentrations to below the standard, review with the Division and implement the plan as approved by the Division.” A progress report is expected by February 1 with regular updates expected throughout the year.
According to the letter from the state, sampling conducted by the mine company on its property between the fall of 2008 and the fall of 2010 showed violations in water quality standards. In May 2009, huge violations of the water quality standards in terms of heavy metals including aluminum, cadmium, copper, iron, lead manganese, pH and zinc were found. The samples in some cases were more than 30 times the upper limit of the state’s standards. For example, the upper limit for cadmium is 4.3 micrograms per liter but 140.6 micrograms per liter were found. The upper limit for aluminum is 750 micrograms per liter. But the sample showed 11,497.9 micrograms per liter…
“I think what happened was that naturally occurring seepage from the mountain after the snowfall runoff picked up some metals,” Larsen continued. “We are the ones monitoring the situation.” “I think what it gets down to is, what is the obligation of any landowner to treat offsite heavy metals that migrate onto your property with heavy runoff. Is that our obligation?
Other landowners in the Crested Butte area might be subject to the same responsibility.” [High Country Citizens’ Alliance executive director Dan Morse] said HCCA feels the polluted water is coming off U.S. Energy’s private land and unpatented mining claims. “We understand there is a bulkhead in the 2000 level of the Keystone mine [2,000 feet below the Mt. Emmons peak] that is holding back about 170 vertical feet of water,” said Morse. “The question is, does all that water create artificial seeps and springs that allows polluted water to reach the surface? Are there fractures in the rock causing this water to get to the surface and ultimately pollute Coal Creek? The fact is, Coal Creek is contaminated with heavy metals… and the question remains, are they from this source?”

From The Pueblo Chieftain (Chris Woodka):
John Klomp, a former Pueblo County commissioner who now sits on the state Water Quality Control Commission, said there aren’t enough people working in the division to police every waterway. At the same time, there needs to be emphasis on Fountain Creek and Klomp is working to assure the manpower is available to evaluate information provided to the state. “Fountain Creek is a higher priority. It needs to be monitored and monitored regularly,” Klomp said.
The Water Quality Control Division listed the primary “workload drivers” that will lead to the shortage of manpower in the memo:
- Population growth, that increases demand for a static or declining water supply and increases the number of permits needed. The state has nearly doubled the number of stormwater permits since 2004, for example.
- New and revised rules and regulations from the Environmental Protection Agency will mean more complex permit enforcement.
- The number of samples requiring evaluation jumped from about 640,000 in 2002 to more than 1 million last year. Court rulings require more things be monitored. For example, a 2009 ruling by the 6th Circuit Court of Appeals overturned an EPA rule exempting pesticide applications from discharge permits. That action alone will increase the number of discharge permits by 2,000, or 20 percent of the state total.
- Aging and failing water and wastewater infrastructure will increase demand for funds, as well as state oversight.
The impacts of trying to keep up with the required work would mean the division has to prioritize inspections, focusing primarily on emergencies. That would reduce protection, the memo states. The division responds to 40 to 60 emergency situations annually.
Right now, the state annually inspects less than 3 percent of 5,500 activities covered under stormwater permits, and less than half of the state’s 2,000 wastewater discharge facilities. About 200 wastewater facilities are discharging domestic waste to groundwater without a permit, endangering the quality of groundwater.
The Colorado Water Quality Control Commission has scheduled a rulemaking hearing in Denver on June 7
May 28, 2010
From The Crested Butte News (Mike Horn):
The majority of the revisions to Regulation No. 31 are being proposed by the Water Quality Control Division, with the Colorado Mining Association and the Colorado Wastewater Utility Council submitting additional proposals. The proposed revisions include changes to criteria for, among others, dissolved oxygen, E. coli, and molybdenum. Temporary modifications of standards and anti-degradation to protect high-quality waters are also on the docket, as is adoption of new provisions authorizing variances to water quality standards in limited circumstances.
