Boulder County Commissioners Respond to Clean Water Act Court Decision

U.S. District Court decision (10/17/24) RE: WildEarth Guardians et. al. vs. Denver Water

Commissioners’ Statement:

The Boulder County Commissioners were pleased to see the decision issued by the U.S. District Court finding that Denver Water’s Gross Dam project violated the Clean Water Act and the National Environmental Policy Act. The Court’s decision is consistent with Boulder County’s long-standing position that the U.S. Army Corps of Engineers failed to consider important issues when conducting its environmental impact analysis. The county is especially gratified that the Court recognized that the Corps’ failure to consider the impacts of climate change on the project violated the Clean Water Act.

It is unfortunate that Denver Water chose to proceed with this project while this litigation was pending. Grave environmental damage has already occurred, and many Boulder County residents have been severely impacted by the project. Although the Court has not yet determined how the Corps should remedy these violations, we are hopeful that significant steps will be taken to protect Colorado’s precious water and environmental resources going forward as required by Federal law.

Gross Reservoir Phase 1 Payments Ended April 30, 2024.

Boulder County has distributed the first round* of payments from Section 2. (“Reduce Impacts to Residents”) of the Denver Water Settlement Agreement. See Gross Reservoir Community Impact Mitigation Fund Phase I Distribution Report for full payment details.

For the most recent updates, please read the e-newsletters posted on the right side column.

* Because Denver Water’s operational plan for tree removal around Gross Reservoir will not be available until mid- to late-2024, there will be two phases of Fund distribution. Phase 1 distributed funding based on ongoing impacts from the full 7-year Gross Dam Expansion Project. Phase 2 will distribute funding based on impacts from the two-year tree removal operations beginning in 2025.

Brief Background Summary

In July 2020, the Federal Energy Regulatory Commission (FERC) issued an Order amending Denver Water’s hydropower license that permitted Denver Water to proceed with the Gross Reservoir Expansion Project. With this Order, Denver Water was able to claim that FERC has “complete authority” over the project and was able to avoid County review of the largest construction project in Boulder County history. In addition, Denver Water sued Boulder County to make sure the County’s local land use (1041) authority was preempted (denied) by federal regulation.

In November 2021, Boulder County reached an agreement with Denver Water to resolve the federal lawsuit by Denver Water v. Boulder County. The settlement directed Denver Water to pay more than $12.5 million to Boulder County to mitigate the impacts of the dam expansion project, including $5 million for a fund to be distributed to area residents to help mitigate noise, light, and air impacts to households near the Gross Reservoir Dam Expansion project.

Gross Reservoir Community Impact Mitigation Fund Community Advisory Working Group

Gross Reservoir Community Impact Mitigation Fund Community Advisory Working Group
From April to June 2023, Boulder County convened a community working group to weigh different scenarios, interests, and collective impacts from both a scientific and subjective standpoint in order to make recommendations to the Board of County Commissioners about a fair process for distributing money from the Gross Reservoir Community Impact Mitigation Fund. The Working Group met five times to consider and discuss the impacts from Denver Water’s project on Gross Reservoir area residents.

The Gross Reservoir Community Working Group met five times to consider and discuss the impacts on Gross Reservoir area residents from Denver Water’s project, from both a scientific and a subjective/experience-based standpoint, in order to make recommendations to the Board of County Commissioners about a fair distribution process. Members of the public were invited to observe and provide written comments during all working group meetings. All meeting notes and documents are provided below.

Gross Reservoir Dam Expansion Settlement FAQ

Denver Water had a strong legal case and the Boulder County stated that it was not going to be able to use its local permitting authority to stop the expansion project. This raises the question of why Denver Water would settle with Boulder County rather than simply waiting for a judgment from the court. In pursuing the expansion project, Denver Water reached agreements with other cities and counties, citing its preference to work with communities rather than have an adversarial relationship. For example, numerous western slope counties, cities, irrigation districts, water authorities, and conservation organizations decided to support the expansion project because of the Colorado River Cooperative Agreement (“CRCA”). Similarly, the City of Boulder and the City of Lafayette agreed to support the expansion project after Denver Water committed to establishing an environmental pool to enhance stream flow in South Boulder Creek during low flow periods. In addition to its preference for working with other Colorado communities, Denver Water was concerned about financial impact that potential delays caused by protracted litigation would have on the expansion project. The settlement removed the uncertainly related to the timeframe of the litigation.

Denver Water made numerous commitments related to the expansion project in the settlement agreement, including a $5 million resident mitigation fund, $50,000 per year for park rangers and other measures during recreation closure, easements for recreational trails, $5.1 million for use in acquiring new County open space, a transfer of 70 acres of Denver Water property to Boulder County for open space, $1 million for a habitation restoration project, $250,000 for a program aimed at minimizing the carbon impact of forest waste, and $1.25 million for a climate innovation/impact fund.

All of Denver Water’s commitments are contingent upon Denver Water’s awarding a construction contract and the project proceeding to construction. Denver Water is required to fulfill most of its monetary commitments when Denver Water begins construction on the dam raise portion of the project (anticipated 2024). Boulder County has received the funding for the $5 million-dollar resident mitigation fund and will be working with Pinyon Environmental and the Gross Reservoir community to determine how best to distribute those funds directly to the impacted community.

The $5 million dollar mitigation fund its intended for use of households near the expansion project who will experience noise, light, and air impacts. The County will hire a third-party contractor with expertise in this area to work with the community to determine impacts, mitigation strategies, and make recommendations regarding fair distributions of the funds. The Commissioners have committed to a transparent process which will include community input into the distribution process.

Once the County has been able to assess all impacts and the County’s contractor has completed its evaluation of impacted households, the Commissioners will determine the process for the distribution of funds. A public meeting has been scheduled for June 29, 2023, for the Boulder County Commissioners to consider recommendations for Phase 1* funding from Section 2. of the Denver Water vs. Boulder County Settlement Agreement.

* Because Denver Water’s operational plan for tree removal around Gross Reservoir will not be available until 2024, the Boulder County Commissioners decided that tree removal impacts will not be considered in the first phase of funding (i.e., money from the full $5 million mitigation fund will be held back for a future round of funding once the tree removal impacts are better known.).

As a result, there will be two phases of funding. Phase 1 will distribute funding based on ongoing impacts from the full 7-year Gross Dam Expansion Project. Phase 2 will distribute funding based on impacts from the 2-year tree removal operations, specifically. The Working Group focused on developing recommendations on the methodology to distribute Phase 1 funding. They also developed recommendations on how much funding to retain for Phase 2 of funding distributions.
