Our 15th Annual Water Seminar, “Risky Business on the Colorado River” was held on September 14th, 2018 in Grand Junction, Colorado.

We heard from speakers with Southern Nevada Water Authority, the Utah Division of Water Resources, a member of the Board of the Colorado Water Conservation Board, the Colorado River District and others as they discussed current conditions on the river and how water is managed.

“This can’t be the United States”: An excerpt from River of Lost Souls — Jonathan Thompson @jonnypeace

Below is an excerpt from Jonathan Thompson’s beautiful book about the people and the historic economies of the Four Corners area and the resultant water pollution, health problems, and climate effects left over from the extractive industries that flourished there. The book centers around the Gold King Mine spill in August 2015 and that is the context Thompson uses to explain the area’s history. He even introduces you to his grandmother and that’s quite a story in itself. River of Lost Souls is an important book. The reader ends up smarter about dealing with folks that disregard environmental issues in the name of economic gain.

From RiverOfLostSouls.com (Jonathan P. Thompson):

Jonathan’s Note: Among the many things in the path of Florence, the tropical storm that battered North Carolina in September, were coal ash dumps. A lot of folks don’t know what those are, or why they are cause for concern. So I’m running this long excerpt from River of Lost Souls: The Science, Politics, and Greed Behind the Gold King Mine Disaster to shine some light on the issue of coal combustion waste.

To drive west out of Farmington is to travel through the borderland, where the northeastern edge of the Navajo Nation melds with the non-Indian world. It’s a cultural and economic mishmash. Here’s a sex store next to a plumbing supply shop across the highway from a sprawling automobile burial ground not far from a Mennonite church. Justalaundry, Zia Liquors, Family Dollar, and numerous little booths or shacks where Diné sell kneel down bread or tamales or piñon nuts to passersby. And the “quick cash” joints that have sprouted like weeds in Gallup, Farmington, and other reservation border towns, preying on the poor, the desperate, and the “unbanked” with their thousand-percent interest loans. It’s just an update of the exploitative pawn shops of yore. “It’s a border town, and tribes around it constitute economic colonies,” John Redhouse, who grew up in Farmington, told me, adding that things haven’t improved that much since the 1970s.

Trailers perched on cinder blocks, tires on a roof. An old man in a recliner, sipping a tumbler of warm whiskey, selling his junk. Down in the lush Jewett Valley a sign pointing to an old metal building reads: “RABBITS GOATS CHICKS AVON AT DOUBLEWIDE.” Just up the road, the Original Sweetmeat Inc., aka “Mutton Lover’s Heaven,” a slaughterhouse and butcher shop, sits alongside the highway and the Shumway Arroyo.

A few miles north looms the San Juan Generating Station, built in 1973 in the arroyo. Eight miles away, on the Navajo side of the river, sits the older, larger Four Corners Power Plant.

The Original Sweetmeats is owned and run by Raymond “Squeak” Hunt, a tall, gruff man prone to muttering inscrutable aphorisms, who deals mostly with mutton, or sheep (as opposed to lamb), and sells to a mostly Diné clientele. “You may think I’m one hard, mean son-of-a-bitch,” Hunt told me when I first met him in 2002, as he unloaded a trailer full of sheep, bound for slaughter. “But it hurts me every time I kill one of these animals.”

I wasn’t there for the sheep, though. I was visiting because Hunt is surely the most stubborn—if unlikely—thorn in the corporate side of Public Service Company of New Mexico, the operators of San Juan Generating Station and the supplier of electricity to the entire state. That doesn’t make him unique; hundreds of activists have agitated against the air pollution from the two coal plants’ smokestacks over the decades. But Hunt was one of the most ferocious fighters against a rarely noticed form of pollution spilling out of the plants: the slag, ash, and dust left over from burning coal, otherwise known as coal combustion waste.

Hunt has lived here, along the banks of the Shumway Arroyo, for much of his life. Prior to 1973 the upper reaches of the Shumway contained water only after rains. Once the arroyo reaches the San Juan River Valley near Hunt’s place, however, irrigation return and groundwater resulted in the arroyo’s transformation to a perennial stream. The stream was a source for both domestic and livestock water for early settlers of the Jewett Valley, including Hunt’s family.

When construction began on the large, mine-mouth, coal-burning power plant a few miles upstream alongside the arroyo, the arroyo changed. Coal power plants require vast amounts of water to function, and when SJGS went on-line in 1973, the plant dumped its wastewater and just about everything else into the Shumway. From that time on, the previously dry arroyo became a perennial stream from the plant to the river. Downstream users in Waterflow, in the meantime, continued to drink out of wells fed by the arroyo’s flows and their livestock kept drinking straight out of the stream.

Like the slightly larger Four Corners Power Plant, which was constructed a decade earlier, San Juan Generating Station’s smokestacks were subject to virtually no regulation. During its first decades of operation, Four Corners became notorious for the black plume of smoke—hundreds of tons of sulfur dioxide and fly ash each day—that it sent into the region’s previously crystal clear skies. One account says that one plant produced more smog than New York City. With the addition of SJGS, the air quality in the region deteriorated, vistas were cut short by smog, and the one thing that remained visible from far away were the plumes emitted by the stacks.

It did not take long for citizen groups from around the region to protest the deterioration in the quality of their air. General citizen pressure and lawsuits forced the 1977 Clean Air Act to include a policy preventing the degradation of air quality. In 1978, San Juan Generating Station installed controls to reduce smokestack emissions and Four Corners followed in 1980. Air pollution from the plants was significantly reduced. Other pollution was not.

When coal is burned the carbon reacts with oxygen to form carbon dioxide. But coal is a lot more than just carbon. It’s got sulfur in it, which becomes sulfur dioxide during combustion, the main cause of acid rain. It contains a host of other elements, most notably arsenic, mercury, and selenium, some of which waft from the stack as smoke and particulates. Most end up as solid waste of one form or another. Each year, power plants in the United States collectively kick out enough of this stuff to fill a train of coal cars stretching from Manhattan to Los Angeles and back three times. It’s stored in lagoons next to power plants, buried in old coal mines, and sometimes piled up in the open. It is the largest waste stream of most power plants, and a study by the Environmental Protection Agency found that people exposed to it had a much higher than average risk of getting cancer.

“Anybody who knows anything about coal ash chemistry knows that when you burn coal, what you have leftover is dramatically different from what you had originally,” Jeff Stant, a geologist with the Clean Air Task Force, told me back in 2002. Coal ash can contain seventeen metals. Some, like mercury or arsenic, are already toxic, others become more so during combustion.

Because every pound of pollution kept out of the air ends up in the solid waste stream, the pollution control methods in the stacks only made the problem on the ground worse. The solid waste consists of fine and dusty fly ash; a gravelly, gray material called bottom ash; and the relatively benign glassy clinkers or boiler slag. The stack scrubbers that pull sulfur dioxide and nitrogen oxide out of the smoke create perhaps the most malignant material, called scrubber sludge. All of that was typically piled up near the plant, where it could blow into the air, or get washed into an arroyo, or leach into the ground. In San Juan Generating Station’s case, the stuff was dumped right into or near Shumway Arroyo—an echo of the hardrock mining tailings that had been similarly dumped for decades one hundred miles upstream.

In the early 1980s, people who lived along the Shumway Arroyo and drank from wells began getting sick. Hunt suffered from muscle spasms, lost sixty pounds, and had a cornucopia of other problems. “I looked like a POW after World War II,” he said. His wife and kids got sick; his neighbors, too.

Though Hunt’s illness was never definitively traced to a specific cause, he and other activists are pretty sure some of the stuff in coal combustion waste made it into his water. Around the time Hunt got sick, researchers found extraordinarily high levels of selenium—which tends to be highly concentrated in coal combustion waste—in the Shumway Arroyo. His symptoms match those of selenium poisoning. His illness may have also come from ingesting too much lead, cadmium, arsenic, mercury, or sulfates, all of which are commonly concentrated in coal combustion waste.

Whatever the poison, it soon became clear that the water was tainted. Those who were sick sued the Public Service Company of New Mexico, which operates the plant; the company never admitted fault, but ultimately settled with the affected families. It also tightened up its waste disposal, becoming one of the first power plants in the nation to go to a zero discharge permit, which means it can’t release any water onto the land. After a lot of legal wrangling, Hunt settled, too.

Hunt, however, remains convinced that the power plant continues to sully the water in the arroyo. He says that water leaks from retention ponds, coal-washing, and dust-control spraying, and even if it’s clean, it picks up and remobilizes contaminants in the sediments of the arroyo, left by the dumping in the 1970s and ’80s. During the late 1990s and early 2000s, 1,400 of Hunt’s sheep, all of which had drunk from the Shumway Arroyo, got sick and died or had to be killed. Hunt blamed Public Service Company of New Mexico, or PNM, the state’s biggest electricity provider. The utility said negligence on Hunt’s part killed the sheep, with the help of minerals occurring naturally in the arroyo and the water. The utility and Hunt have been at loggerheads for years in very public ways. On their way home from work every day, the power plant’s employees have no choice but to see a giant billboard erected by Hunt on his property, bashing both PNM and New Mexico’s environmental regulators. A smaller sign above the big billboard reads: “WAKE UP you bunch of NUTS we ALL live DOWNSTREAM.”

Hunt’s fight isn’t limited to his own situation, though. He’s also worked to shine a light on the coal combustion waste issue in general. Despite the magnitude of the waste stream, and its potentially deleterious effects on human and environmental health, coal combustion waste disposal is regulated much like normal landfills are. The EPA has for decades worked on new rules, implementing some, letting others fall by the wayside.

“I hope you have a cast-iron stomach,” said Hunt as we walked over to the little stand by the road where a Diné couple was selling, along with jewelry, bowls of extremely hot chili and kneel down bread. The lamb sandwiches inside looked good at first, but after a tour of the slaughterhouse and witnessing a sheep get stunned, decapitated, and dressed, I opted for the chili. We sat in a shady spot next to the parking lot and watched a steady stream of customers go into the butcher shop and haul out racks of lamb and mutton, chops, and something a Diné man called b’chee, little strips of meat or fat wrapped up in sheep intestines that Hunt’s wife prepared.

After eating, as the afternoon clouds moved in along with a stiff breeze, we climbed into Hunt’s truck and he drove us to the south side of the river, toward Four Corners Power Plant. We followed a dirt road skirting Morgan Lake, in the shadow of the soot-stained smokestacks of the plant. Each year about nine billion gallons of water are brought up from the San Juan River to form this reservoir, then it’s circulated through the plant to cool the massive generators and for other purposes. The hot water is discharged back into the reservoir, so Lake Morgan is warm and steamy, even in winter, making it a popular, if surreal, windsurfing and fishing spot.

When early provisions of the 1970 Clean Air Act first were being implemented in the early 1970s, the smokestacks looming over Lake Morgan kicked out more than four thousand pounds of mercury each year, along with thousands of pounds of selenium and copper and hundreds more pounds of lead, arsenic, and cadmium, not to mention sulfur dioxide, nitrogen oxides, and other pollutants. Thanks to federal air pollution regulations, and to activists who push the government to enforce those rules, emissions have decreased considerably over the years. Now, with only two of five units still in operation, the plant puts out about 150 pounds of mercury and 520 pounds of selenium each year, along with varying quantities of other toxic metals. Most of these pollutants are then deposited in the surrounding water, on the land, and on homes. For years, rain and snow falling on Mesa Verde National Park—its backside visible from the shores of Morgan Lake—have contained some of the highest levels of mercury in the nation, and elevated levels have even been found on Molas Pass, just south of Silverton. The mercury is then taken up by bacteria in lakes and rivers, which convert it to highly toxic methylmercury, which then enters the food chain. Mercury messes with fishes’ brains, and even at relatively low concentrations can impair bird and fish reproduction and health. It’s not so good for people, either.

We continued out into the desert toward the Chaco River and the Hogback, and as we came over a rise an incongruous scene unfolded before us: a flat-topped, uniformly shaped mesa, its dusty soil gray and smooth, with eerie-looking deep-orange water pools on its surface. Nothing was growing there. I wondered if maybe it was this that I needed a strong stomach for, not the chili.

We were looking at the Four Corners Power Plant’s dump, made up of ash impoundment piles, decant water, and evaporation ponds, containing some forty years’ worth of accumulated coal combustion waste—tens of millions of tons of it—from three of the plant’s five generators. At the time, Four Corners was burning about 8.5 million tons of coal each year, some 3.3 million tons of which were leftover as coal combustion waste, dumped both here and back into the nearby mine. A trio of unlined sludge-disposal ponds sat less than five hundred yards from the Chaco River, which empties into the San Juan River a few miles away. Two miles upstream is the Hogback Outlier, a Chacoan-era pueblo. A crescent-shaped structure known as a herradura—a piece of AWUF associated with Chacoan roads—sits atop the Hogback nearby.

Darker clouds headed our way and the wind kicked up, whipping the fine, gray ash and dust off the top of the piles and into the air, reducing visibility to thirty feet or so. When the dust cleared we saw a sign stuck into the base of one of the piles. It read: “No Trash Dumping. Walk in Beauty.”

For people who worry about coal combustion waste and the way it’s regulated, this place is Exhibit A. “My first thought when I saw this,” Lisa Evans, an attorney for Earthjustice, told me, “was, this can’t be the United States.”

Like the Shumway Arroyo which runs past Hunt’s home, the Chaco River downstream from this complex of ponds and piles has contained extremely high levels of selenium, as does the groundwater beneath the ponds. When ingested, selenium can adversely affect reproduction in fish, birds, and mammals. Fish along this stretch of the San Juan River often contain elevated levels of mercury, lead, selenium, and copper. In 1992 a U.S. Fish and Wildlife biologist surveyed fish downstream on the San Juan River from the Four Corners Power Plant to Mexican Hat and found that a majority of them had lesions, damaged livers, deformities, or other signs of disease. While the culprit appeared to be bacteria, the particular strains need the fish to be otherwise impaired, by contaminants, for example, in order to invade.

When I returned to Hunt’s place in 2007, he gave me the same tour. Nothing had changed, but the spokesman for the plant’s operator, Arizona Public Service, assured me that they were no longer dumping their coal ash in the piles Hunt and I toured, and that the company planned to clean up the nasty piles and ponds and replace them with lined impoundments. Since then, the piles have been covered, and the old ponds removed. Dumping continues here, but under more controlled conditions. Ash is also dumped back into the nearby coal mine, which has been owned by a Navajo Nation-owned company since the end of 2013. This alleviates some of the problems associated with dumping, but doesn’t solve all of them, critics say. Chemicals can still leach into groundwater (though it’s less likely here, where it’s so arid), and unless the ash is covered, it can still blow around in the air, settling on nearby homes.

Arizona Public Service, which is owned by Pinnacle West Capital Corporation, sells electricity to nearly 1.2 million people across Arizona. The corporation raked in over $400 million in profit in 2015. At the same time, it lobbied hard to change state rules on net metering, which determine how much the utility must compensate homeowners for electricity generated by rooftop solar panels. They’ve managed to chip away at the incentives, thus discouraging people from installing their own panels and generating a bit of their own electricity.

As we drove back around the plant, seemingly to provoke the security guards, Hunt treated me to another rhetorical geode. “It’s just like asking Patty Hearst’s mother what happened…all you get is a bunch of excuses,” he said. “These are some nasty sons-a-bitches. It’s all about profit. They don’t care about anything or anyone, they just care about their profits.” As crude as the delivery might have been, it was hard to refute the concept.

When we arrived back at Original Sweetmeats, the after-work rush was on. We hung back by the truck and watched. It was late afternoon. The cottonwoods cast long shadows on the ground. “If I’m lucky, one day I’ll die of a heart attack,” Hunt said.

After a pause, he perked up to tell me about the petroglyphs that are pecked into the sandstone cliff band that runs up and down the San Juan for miles. I looked out at the valley, sliced up by the four-lane highway and the big transmission towers, and wondered why the Pueblo people would leave such a place, and I tried to imagine what the first Diné people, coming from the North, out of the cold mountains and across the parched high desert, thought when they came upon the silty river and the trees and the willows on its banks. It must have felt like home.

Up on the desert on either side of the valley, the plants chugged on, each burning twenty thousand tons of coal per day. They’ve brought jobs and industry to a once-impoverished and undeveloped place and keep the people in faraway cities cool in the unforgiving summer heat. They each send millions of dollars of property taxes and royalties to various governments. They also spew out thousands of tons of toxic waste each year. Power is not free.

An old pickup truck pulled into the parking lot, several cages holding roosters in the back. A large man tumbled out, wearing safety glasses and a dirty jumpsuit, his face spattered with some kind of black soot: a power plant employee, selling his chickens after work.

“Five dollars for the little ones,” he told a man and wife who were inspecting the birds. Then he turned to Hunt and me and told us about how he can no longer smell anything after years at the plant, and about how his friend who lived nearby had to clean his television screen daily to wipe away the buildup of fly ash.

“I won’t make it to sixty, I can guarantee that,” he said, matter-of-factly. His wife sat in the cab of the pickup, smiling and quiet.

The haze seemed to be getting thicker in the west, the sun taking on an orange glow. Under my breath, to no one in particular, I said, “Looks like it will be a nice sunset tonight.”

Construction begins on Southern Water Supply Project II

Crews from Garney Construction have started work on a new pipeline project to bring reliable water supplies to four water providers in Boulder and Larimer counties.

Called the Southern Water Supply Project II, the pipeline will deliver additional Colorado-Big Thompson Project and Windy Gap Project water from Carter Lake to the city of Boulder, town of Berthoud, Left Hand Water District and the Longs Peak Water District.

The $44 million project includes more than 20 miles of steel pipe that will improve water quality and at some portions of the year will act as the primary source of raw water for the project’s participants.

Officials estimate the project will be complete in early 2020.

Mandatory curtailment of water rights in #Colorado raised as possibility — @AspenJournalism @CWCB_DNR #ColoradoRiver #COriver

Water experts say that if the ongoing drought persists, Lake Powell could be empty within three years, and call could be placed on the upper basin to curtail water rights. To avoid the chaos such an unprecedented call might bring, state officials are discussing how a more orderly, but still mandatory curtailment of water uses, might need to be implemented.

From Aspen Journalism (Brent Gardner-Smith):

A state-imposed mandatory curtailment of water in the Colorado River Basin within Colorado was discussed as a looming possibility during a meeting of the Colorado Water Conservation Board on September 19 in Steamboat Springs.

Representatives from the Western Slope told the statewide water-planning board that while they favor creating a new legally protected pool of water in Lake Powell and other upstream federal reservoirs to help prevent a compact call on the river, they have significant concerns about the pool being filled outside of a program that is “voluntary, temporary and compensated.”

However, Front Range water users told the board that a voluntary program may not get the job done and that a mandatory curtailment program, based on either the prior appropriation doctrine or some method yet to be articulated, may be necessary to keep Lake Powell and Glen Canyon Dam functioning so Colorado, Utah and Wyoming can deliver enough water to California, Arizona and Nevada to meet the terms of the 1922 Colorado River Compact.

“With the repeat of historic hydrology beginning in the year 2000, Lake Powell will be dry, and when I say dry I mean empty, within about three years,” Jim Lochhead, CEO and manager of Denver Water told the CWCB board.

Lochhead said that while a voluntary demand management program might help bolster water levels in Lake Powell, “it doesn’t necessarily solve the problem.”

“So we may need — I know we don’t want to implement — but we may need other mechanisms to accelerate the creation of water into Lake Powell in the event of an emergency,” Lochhead said. “This is not something that Denver Water wants, or is asking for. What we are asking for is that the contingency plans be put into place. We need to have those plans in place before the system collapses.”

On Wednesday, Brent Newman, the chief of CWCB’s Interstate, Federal, & Water Information Section emphasized that neither they, nor the state attorney general’s office, is at this point “assessing, pursuing or recommending to the CWCB board any type of involuntary or ‘anticipatory’ curtailment scenario.”

And yet, such scenarios are on a lot of people’s minds.

(Please see related memo, slides and audio from the meeting. The audio is via YouTube, as provided by CWCB. The file opens well into the discussion, so click back to the beginning of the file, which opens just after the agenda item began, with brief introductory comments from CWCB Director Becky Mitchell. It’s well worth listening to. Also please see related story from Sept.18.).

The looming possibility of mandatory curtailment of water use has raised concerns among Western Slope water managers, who feel that such cuts could harm Western Slope agricultural, such as this hay filed in the Yampa River basin. However, as water levels continue to drop to record lows in Lake Powell, mandatory curltailments are being discussed as a real possibility, especially by Front Range water managers.

At hand

Lochhead said Denver Water wants to see a voluntary, temporary and compensated program created as a “first priority,” but also said “I also don’t think that by not talking about mandatory curtailment we can pretend the problem will go away. We need to be thinking about it, and we need to be thinking about it proactively.”

However, Western Slope water interests as represented by the Colorado River Water Conservation District and the Southwestern Water Conservation District are concerned that if a new storage pool is created in Lake Powell, and a mandatory curtailment program is used to fill it, it could have dire consequences for agriculture on the Western Slope.

NPR panel discussion of The Future of Water at CSU May 24, 2016. L to R: Patty Limerick, Roger Frugua, Melissa Mays, Paolo Bacigalupi, Kathleen Curry, and host Michel Martin.

“This is our livelihood,” Kathleen Curry, a rancher in Gunnison who serves on the Gunnison River Basin Roundtable, told the CWCB. “This water is what we depend on. If we move in the direction of mandatory curtailment, and it isn’t equitable, you are going to have significant impacts to the water users in the state of Colorado, especially on the Western Slope.”

The two regional Western Slope water conservation districts had drafted a resolution they wanted the CWCB to adopt Wednesday, which did not happen, as the CWCB declined to vote on it.

The resolution stated that any mandatory curtailment program would be developed on a “consensus basis” with the two districts at the table, and not just be a directive of the state.

However, Bennett Raley, the general counsel for the Northern Water Conservancy District, which provides water to nearly a million people in northeastern Colorado, said the state, as a sovereign entity, should not be constrained by consensus.

He also said that mandatory curtailment may well be necessary in Colorado.

“If the drought continues, there are two paths,” he told the CWCB board. “If there is an infinite source of money, then voluntary works. Great, we’re all happy. If the drought continues and there is not an infinite source of money, then the state will go to mandatory. The Supreme Court will ensure that, sooner or later, it’s not a question.”

Part of the fear of such a mandatory program is that hardly anyone, outside of perhaps the state engineer, knows what it would look like.

“Ultimately it’s a state decision, it’s a decision of the state engineer as to how water rights would be curtailed to meet the state’s obligations under the Colorado River Compact,” said Lochhead, when asked after the meeting how mandatory curtailment would work. “The short answer is, I don’t know. There are a lot of questions and viewpoints.”

Lochhead did say Denver Water is willing to “work with the state and with the West Slope to ensure that any curtailment doesn’t disproportionally impact any region of the state, whether it’s on the West Slope or the Front Range, and that essentially the same rules apply to everybody.”

@USBR revises release forecasts for Olympus and Ruedi dams

Map of the Colorado-Big Thompson Project via Northern Water

From email from Reclamation (James Bishop):

Due to revised demands, releases from Olympus Dam to the Big Thompson River are scheduled to rise from 83 to 101 cubic feet per second (cfs) tonight at midnight (cusp between Thursday and Friday), 21 September. Earlier this week I announced releases from Olympus Dam were planned to rise to 225 cfs and that figure has since changed significantly.

At this point in our forecast, we do not anticipate releases to the Big Thompson River rising above 150 cfs as we use the river to deliver C-BT Project water. On that subject, use of the Big Thompson to make project water deliveries is slated to run through October 12, and those deliveries vary frequently. I will of course continue to provide updates while keeping in mind the old adage: “Plans are disposable. Planning is indispensable.”

A map of the Fry-Ark system. Aspen, and Hunter Creek, are shown in the lower left. Fryingpan-Arkansas Project western and upper eastern slope facilities.

From email from Reclamation (James Bishop):

Yesterday, I messaged you that we at Reclamation no longer planned to increase releases to 400 cubic feet per second (cfs) from Ruedi Dam to the Fryingpan River but would instead be maintaining releases at 355 cfs. That change holds, but I wanted to further explain this.

Due to the persistence of very low river flow conditions in the Colorado River, the U.S. Fish and Wildlife Service, in coordination with Reclamation engineers and other Program partners, has decided to reduce the rate of release of Endangered Fish Recovery Program water stored in Ruedi Reservoir to allow these releases to be extended further into October. The reduced rate of release will enable a longer duration of “fish water” to be delivered to the 15-Mile Reach over the upcoming weeks, optimizing its benefits to the endangered fish.
