Boulder inks deal to sell hydroelectric power to Tri-State

Small hydroelectric via City of Boulder.

From BizWest (Jensen Werley):

The city of Boulder signed a contract with the Tri-State Generation and Transmission Association for the sale of hydroelectric power generated at five of the city’s eight hydroelectric plants.

The deal is a 10-year agreement with an option to renew for another five years. It’s expected to generate about $500,000 per year in revenue, which will offset water utility capital improvements and operating costs that would otherwise be paid through higher water rates for customers.

The city had previously sold hydroelectric power to Tri-State from the Boulder Canyon Hydroelectric plant. This agreement renews the contract for Boulder Canyon and adds four facilities: the Kohler, Maxwell, Orodell and Sunshine plants…

Hydroelectric generation harnesses the energy generated during the downhill trip from water sources to the water distribution system. Boulder’s hydro program consists of eight plants that generate about 37 million kilowatt-hours of electricity annually, enough to power 4,600 households and displace 20,400 tons of coal.

From The Boulder Daily Camera (Anthony Hahn):

Issues surrounding the long-heralded CU Boulder South annexation plans continue to manifest most consistently within concerns over how eventual flood mitigation designs will play out on the property.

Those concerns were clear at a joint meeting between Boulder’s Water Resources Advisory Board and Open Space Board of Trustees on Monday, where dozens of residents from Boulder’s Frasier Meadows retirement community who wore bright orange shirts reading “Save our neighborhoods” and “Stop flooding of South Boulder Creek” urged officials to take quick action on those plans.

Upon annexation of the property by the city, the University of Colorado plans to build more than 1,000 housing units for students and employees, athletic fields and academic buildings on the 308-acre site over the coming decades. It also intends to devote nearly 100 acres of the site to a flood mitigation plan.

The parcel has proven controversial since its purchase in 1996, as neighbors have worried that university’s plans to eventually develop the site would put nearby homes at greater risk from floodwaters.

The chief flood mitigation concept — proposed under the South Boulder Creek Master Plan — includes a flood wall along the south side of U.S. 36 within the Colorado Department of Transportation right-of-way and a dam along the northern portion of the CU South parcel to contain flood waters, according to a staff report presented Monday.

Under this plan, vehicle access to CU South from Table Mesa Drive would be routed to a ramp up and over a portion of the dam. The flood wall would also include an overtopping spillway, which would be designed to discharge floodwaters “that exceed the design storm.”

“…why I support Denver Water’s Gross Reservoir Expansion project” — Lurline Underbrink Curran

From The Boulder Daily Camera (Lurline Underbrink Curran):

I would like to share why I support Denver Water’s Gross Reservoir Expansion project.

While located in Boulder County, the project obtains the water from Grand County — a county that is currently the most impacted county in the state of Colorado for transbasin diversions. You must wonder why the county and its citizens, stakeholders in the Colorado River Basin, along with Trout Unlimited support this project.

The reason is the Colorado River Cooperative Agreement, which is an historic agreement with statewide environmental benefits which were fought for and gained through sometimes difficult and long negotiations. It has been hailed as a new paradigm and one that will serve as an example of what can be gained when dealing with a finite resource like water. The signatories to this agreement represent the entire Colorado River Basin, and I had the honor of acting as Grand County’s lead negotiator in this agreement. I worked for Grand County for 33 years, retiring as county manager in 2015. I have lived in Grand County over 60 years and have deep roots and interest in the well-being of our waterways.

The environmental benefits gained by Grand County, which include additional flows, river ecosystem improvements, use of Denver Water’s system, participation in an adaptive management process called Learning by Doing, money for river improvements, just to name a few, are necessary to protect and enhance the Fraser and Colorado rivers. Without these benefits, these rivers will continue to degrade, with no hope of recovery or improvement.

Those who oppose the project offer no solutions to the already stressed aquatic environment of the Fraser and Colorado rivers. Through the Learning By Doing format and a public private partnership, partners have already implemented a river project on the Fraser as an example of what can be done. This project immediately produced improvements that were astounding. Colorado Parks and Wildlife can verify this claim. This essential work will not continue without the CRCA.

The impacts that are associated with the construction of the Gross Reservoir Enlargement are substantial and one sympathizes with those who will experience them, but the reality is they will end. Mitigation for the construction impacts can be applied. However, without the CRCA, the impacts to the Fraser and Colorado rivers will continue with no hope of improvement.

The environmental enhancements and mitigation that are part of the CRCA cannot be replicated without the reservoir expansion project, and the loss of these enhancements and mitigation will doom the Fraser and Colorado rivers in Grand County to environmental catastrophe.

Boulder County asks FERC to deny @DenverWater’s Gross Dam hydroelectric permit amendment for the Moffat Collection System Project

From Boulder Daily Camera (Charlie Brennan):

Citing the success of Denver Water’s conservation efforts since it first issued its “purpose and need” statement for the project, and the fact that no service shortfall has yet materialized for its 1.4 million customers in the metro area, Boulder County Attorney Ben Pearlman said that based on prior environmental reviews, “Boulder County does not believe Denver Water has shown that the project’s purpose and need have been met and the FERC must deny Denver Water’s application to amend its permit.”

[…]

“We don’t think they have undertaken the duty they have (under federal environmental law) to analyze this problem thoroughly,” [Conrad] Lattes said…

Denver Water officials on Friday answered back by reasserting the project’s merits.

“The Gross Reservoir Expansion project represents an enormous amount of work, input and collaboration to ensure it is done in the most responsible way possible,” Jim Lochhead, Denver Water CEO/manager said in a statement. “And Denver Water will continue to develop noise, transportation and tree removal plans with input from stakeholders to minimize the impacts to Boulder County and its residents.”

Boulder County comes out against FERC issuing @DenverWater’s requested license amendment for Moffat Collection System Project

Here’s the letter from Boulder County to FERC via SaveTheColoradoRiver. Here’s an excerpt:

Boulder County is an intervenor in this action and offers the following comments on the Supplemental Environmental Assessment (EA) issued by the FERC’s staff on February 6, 2018, related to the Gross Reservoir Hydroelectric Project (FERC Project No. 2035-099).

As detailed below, Boulder County continues to object to the FERC issuing Denver Water’s requested license amendment. The FERC staffhas failed to address significant issues related to the project; as a result, approval by the FERC is premature and would result in negative and unnecessary impacts on the residents and natural resources of Boulder County.

The EA analyzes only those potential environmental effects of oe·nver Water’s proposal to expand Gross Dam and Reservoir which were not addressed in the 2014 Final EIS prepared by the Army Corps ofEngineers (Corps). The FERC’s staffreviewed the EA, made a finding of no significant impact, and recommended approval by the Commission, as mitigated by environmental measures discussed in the EA.

This approach is flawed because ofthe resulting narrow scope ofthe EA, the lack ofspecificity related to adoption of mitigation measures for project impacts, and the FERC staffs wholesale and unquestioning adoption of the Army Corps of Engineer’s Final Environmental Impact Statement (FEIS), which FEIS was completed on April 25, 2014, and for which a Record of Decision was issued on July 6, 2017. The FERC should determine that both the FEIS and the EA fail to meet the standards ofthe National Environmental Policy Act (NEPA) and therefore reject staff’s unreasonable approach.

FERC extends Gross Reservoir hydroelectric license comment period to April 9, 2018

From The Boulder Daily Camera (Charlie Brennan):

The Federal Energy Regulatory Commission, which is weighing a Denver Water request to raise the Gross Reservoir Dam, expand the reservoir and amend its hydroelectric license for the utility, issued a supplemental environmental assessment of the plans Feb. 6. At that time, the commission set a 30-day window for public comment on the document, set to expire March 8.

Save the Colorado and The Environmental Group of Coal Creek Canyon, through Boulder attorney Mike Chiropolos, and, separately, WildEarth Guardians, filed requests to extend that comment period by 60 days.

“Upon consideration, we find that a 30-day extension is warranted,” the commission’s secretary notified parties in a letter on Tuesday. Comments on that supplemental environmental assessment are now due to FERC by April 9…

Tim Guenthner and his wife, Beverly Kurtz, who live in the Lakeshore Park neighborhood on the north side of the reservoir, have studied issues around the proposed project for years.

Guenthner, with his background in engineering, has concerns about environmental, quality of life and safety considerations relating to Denver Water’s plans for development of an on-site quarry at Osprey Point, as well as the use of roller-compacted concrete to enlarge the dam. That’s a technique that he says has never been applied to a dam project at so great a scale. Previously, a dam raise of 117 feet at San Vicente Reservoir in San Diego County was the highest using this technique — not only in the United States, but the world…

The couple, who are part of The Environmental Group of Coal Creek Canyon, urge those interested in learning more about the $380 million Denver Water project to attend a meeting at 3:30 p.m. Sunday at the Coal Creek Canyon Improvement Association Community Center located at 31528 Coal Creek Canyon Road. The session will be used to plan social media campaigns and educate the public about the project’s current status and implications.

@NOAA: 50 trips around the Sun collecting CO2 samples on Niwot Ridge

From NOAA (Theo Stein):

A climate science milestone on Colorado’s Continental Divide

On January 16, 1968, in a bracing chill at 11,568 feet above sea level, a Colorado researcher collected an air sample at Niwot Ridge, on the doorstep of the Indian Peaks mountain range. The sample was carried down the mountain and then measured for carbon dioxide at a lab in Boulder, Colorado. The result: 322.4 parts per million.

NOAA was not officially established until 1970, but this air sample produced the first measurement for NOAA’s Global Greenhouse Gas Reference Network. In the 50 years since, more than 274,000 air samples have been collected at over 60 sites around the globe, including more than 9,000 at Niwot Ridge. All have been transported to what is now NOAA’s Global Monitoring Division labs in Boulder for measurements of carbon cycle gases, like carbon dioxide, methane, carbon monoxide and other gases.

From this inauspicious start, NOAA’s Global Greenhouse Gas Reference Network has evolved into one of the international climate science community’s most valuable resources – a long, uninterrupted and highly accurate accounting of Earth’s changing atmosphere.

Air samples are collected on a weekly basis from locations spanning the Canadian Arctic to the South Pole – continental sites ranging from deserts to tropical forests to barren ice caps, on small islands, and on ships crossing the oceans, by scientists and technicians, as well as soldiers, ranchers, mariners, school teachers, lighthouse keepers, a monk, and a host of other volunteers. One dedicated group of volunteers in Mongolia sends a hearty soul on a 12-hour overnight train ride once a month to deliver air samples to a shipping destination.

Over the years measurements were refined and added, and now samples are analyzed for as many as 60 different trace gases, some at a resolution of parts per trillion. Collection and measurement methods have changed over the decades, but extraordinary steps taken to ensure accuracy mean that historical data are valid and continue to be used by researchers around the world to understand the carbon cycle.

Thanks to that 1968 Niwot Ridge sample, NOAA’s Global Greenhouse Gas Reference Network database is the third-longest continuous carbon dioxide record in the world, behind the Scripps Institution of Oceanography’s Mauna Loa, Hawaii, and Antarctic records. NOAA maintains independent sampling stations at Mauna Loa and the South Pole as well.

On January 15, 2018, almost 50 years to to the day since the first sample was collected, a researcher sampled the air at Niwot Ridge. This time, instruments measured 410.24 ppm of carbon dioxide, an increase of 27 percent over that first sample.
