Town of Torrey, Greenidge Sued Over Bitcoin Mining Project’s Potential Thermal Effects on Seneca Lake

DRESDEN, Dec. 19, 2020 — Three environmental groups and 30 individuals are seeking a court injunction to block construction or operation of a Bitcoin data mining facility at the Greenidge Generation power plant. 

The Town of Torrey and its Planning Board are charged with failing to seriously consider whether Greenidge’s bitcoin mining operation will lead to more heated water discharges into Seneca Lake.

The Sierra Club, Committee to Preserve the Finger Lakes, Seneca Lake Guardian and others filed an Article 78 petition Thursday in Yates County Supreme Court against Greenidge Generation LLC, the Town of Torrey and the Torrey Planning Board.

The petitioners claim a planned expansion of Bitcoin mining will create more harmful warm water discharges into Seneca Lake.

Greenidge, a power plant fueled by natural gas, has state permits to provide power to the electric grid during periods of peak demand. But due to light demand in recent years, the plant has operated only intermittently and far below its generating capacity.

Beginning in early 2019, the plant began processing bitcoin transactions with on-site data equipment that draws on plant-generated power that never reaches the grid. State officials say that energy-intensive activity doesn’t violate its state permits.

Greenidge launched its Bitcoin mining operations early last year.

Earlier this year, Greenidge applied to the Town of Torrey to significantly expand the bitcoin data center by adding four new buildings to house computers and cooling equipment. The company has said it expects that future bitcoin processing demand will allow the plant to operate at full capacity, full time. 

The Article 78 petition alleges that Torrey officials violated the State Environmental Quality Review Act by minimizing the environmental consequences of the planned expansion. They have given their approval without requiring a full environmental impact statement, or EIS.

“Greenidge sought approval of this project through two separate but interdependent approval applications, thus segmenting their request for approval,” the petition said. 

In granting the first approval in October 2019, the Torrey Planning Board allowed for data center operations within the existing power plant as a “Type 1” project under SEQRA. Although Type 1 actions “are likely to require an EIS,” the Planning Board concluded that the project would have “no significant impact on the environment” and waived the EIS.

Months later, Greenidge sought additional approval from the Torrey Planning Board to construct the four buildings. The petition alleges that the Planning Board improperly designated the second project as an “unlisted action,” which under SEQRA rules are “less likely than Type 1 projects” to have a significant environmental impact. Again, the EIS was waived.

SEQRA regulations require that any project that will use more than 2 million gallons of water a day must be designated as a Type 1 project. Greenidge’s DEC permit allows it to withdraw nearly 160 million gallons a day.

The Article 78 petition alleges that the Planning Board decided that it was not required to “take a hard look at the need for additional water to cool the generating station and the discharge of super-heated water into Seneca Lake.”

Most of the 30 individuals who signed the petition cited the negative impact of the plant’s warm water discharges — killing fish and raising the likelihood of harmful algal blooms, or HABs, where they enjoy swimming and boating.

For example, Linda and Phil Bracht said their “everyday use and enjoyment of Seneca Lake is diminished and their health may be harmed” by Greenidge’s expanded bitcoin mining operations. Their lakefront property on Arrowhead Beach Road is just north of the Keuka Outlet, where warmed Greenidge discharge water flows into the lake.

Eileen Moreland, a neighbor of the Brachts, claimed harm to her “home activities (including drinking, bathing, laundry, brushing teeth), swimming, kayaking, fishing and other water sports.” 

Many of the petitioners also complained that they expect a substantial increase in the noise they already hear from the plant.

The petition, filed by Buffalo attorney Richard Lippes, claims the Planning Board deferred receiving noise data until after granting project approval, an alleged violation of SEQRA.

The town and Greenidge have not filed formal responses to the petition, but the company did present a lengthy defense of its application process to the Torrey Town Board on Oct. 13. 

“Despite what some people have claimed,” the Greenidge statement said, “even with this (bitcoin expansion) project our plant will remain firmly inside the environmental limits set by the state and federal governments.

“For example, and it’s an important one: this new project will not increase the water withdrawal or discharge form the plant into Seneca Lake.”

But the local petitioners argue that the planned dramatic increase in power output from the plant will inevitably boost the amount of Seneca Lake water needed to cool plant equipment.

In September, Committee to Preserve the Finger Lakes had asked the DEC to suspend, revise or revoke Greenidge’s four main air and water permits. On Oct. 23, the agency responded, saying: “The facility is in compliance with the terms and conditions in all permits … We will not be suspending, modifying or revoking the Greenidge permits.” 

The petition filed this week against the Town of Torrey does not target either the DEC or the state Department of Public Service, each of which have issued Greenidge permits without requiring an EIS. 

Courts have rejected bids by Sierra Club and others to revoke Greenidge’s state air and water permits issued by DEC.

And in June, the state Public Service Commission ruled that Greeenidge’s use of unmetered electricity to power banks of computers that mine Bitcoin is not subject to PSC regulation. 

John Howard

The commission voted 5-0 on the question, noting that environmental issues were “beyond the scope” of their ruling.

Only one commissioner voiced qualms. Commissioner John B. Howard said the Greenidge case “portends something we should be careful of.”

Referring to the DEC, Howard said: “I think our partners in the environmental regulatory realm need to be (alert), particularly as we decarbonize our generation system.”

Seneca Lake Pure Waters Association had urged the PSC to exercise regulatory authority over Greenidge’s use of energy to process Bitcoin transactions. Jacob Welch, SLPWA’s president, said the commission should not be ‘fooled’ by Greenidge’s efforts to sidestep oversight. He cited unresolved thermal discharge questions.

SLPWA is not a party to the Article 78 petition filed this week.

Meanwhile, Seneca Lake Guardian is asking Finger Lakes residents and businesses to sign letters to Cuomo expressing opposition to the Bitcoin expansion plan.

SLG also questioned whether the increases in greenhouse gas emissions associated with a dramatic increase in “behind-the-meter” power generation for Bitcoin mining at Greenidge would even be counted in new state limits for GHG. Under Cuomo’s Climate Leadership and Community Protection Act, statewide GHG emissions face reduction deadlines in 2030 and 2050.


  1. Most publications state that the plant is gas powered. However, this plant can burn up to 19% biomass according to their DEC permit. I have not seen anything published discussing how the ash will be disposed of, other than “The ash is then processed for proper disposal.” and “Maintaing the outdoor biomass storage piles and limiting the speed of trucks as appropriate to minimize fugitive emissions to the maximum extent possible.”

    As the plant increases production, will the existing ash pile be used, will a new pile be started, will the ash be loaded onto trucks and taken elsewhere? What is the plan to dispose of this ash?

    From the DEC permit:

    Greenidge Generation LLC will operate Unit 4 electric generating operations
    without the use of coal or fuel oil. Electric generation is powered by a boiler,
    with a maximum heat input of 1,117 million BTU per hour. The boiler will burn
    natural gas, with the ability to co-fire up to 19% biomass, which may include
    untreated wood and resinated wood. With conversion of all generating
    operations to use natural gas as the primary fuel with up to 19% biomass
    co-firing, and operations as proposed, the Greenidge Generating Station will
    primarily emit contaminants from boiler powered electric generation and ash
    handling operations.


  2. This lawsuit is another attempt to circumvent the prior losses which the opponents of the Greenidge Project have been dealt by the NYS judicial system. We appreciate the strong support we have received from local government leaders; as was recently reaffirmed by DEC, Greenidge possesses all of the required permits from DEC and Greenidge is operating in full compliance with those permits. The majority of the alleged harms complained of in this new action relate to environmental issues associated with the use of Seneca Lake water. The Town Planning Board does not have the authority to negate those rights granted to Greenidge in its validly existing permits. This complaint seeks to re-litigate those same environmental issues repeatedly determined by the Courts in favor of DEC and Greenidge. As such, there once again is nothing to see here.” I live work and fish here i also am a avid Kayaker ..We at Greenidge care about our environment . we take our job seriously and i am offended by these false accusations.
    This my job !!! our company spends a lot of time and resources taking care of our area and the local community
