County staff recommend allowing small‑scale crypto rigs at inactive oil sites as accessory use; board signals support
Summary
Routt County planners want small on‑site power use for accessory crypto rigs allowed at low‑producing oil wells to avoid flaring, subject to strict permit conditions.
Routt County planning staff told commissioners they found 19 permits in county records but only 13 physical oil wells remain; eight of those are producing. Several well operators had asked whether field gas could be used on‑site to power small data‑processing operations (cryptocurrency rigs) as an alternative to flaring.
Why it matters: The state prohibits routine flaring and encourages “beneficial use” of field gas instead. County staff said some alternatives (like gas‑to‑liquids or gas‑liquid processing) are impractical at very small well sites and that small on‑site electrical generation to run accessory equipment may be the most feasible way to avoid flaring at low‑production wells.
What staff reported: Planning staff reviewed the location and status of county wells; they mapped a small cluster near Hayden and confirmed setbacks: most wells are more than 2,000 feet from occupied structures and only one well had a nearer home. They also reviewed state regulatory language and operator feedback that treating remote field gas as an on‑site fuel for generators is technically feasible, though it does not produce pipeline‑quality gas without additional processing.
Staff recommendation: Planning recommended amending the Unified Development Code (UDC) to allow small‑scale data‑processing/crypto rigs as an accessory use to both existing and new mineral extraction uses, with strict performance standards (noise mitigation, mufflers, directional exhaust, limits on scale and hours of operation) and an explicit public permitting process. The county’s rationale: restricting the allowance only to existing wells would create fairness and property‑access concerns for mineral owners who might seek new wells under similar circumstances.
Board response: Commissioners agreed with staff’s recommendation and asked staff to draft a code amendment that would: (1) classify crypto/data processing as accessory (not a primary industrial use); (2) cap the size and electrical load appropriate to low‑production wells; (3) require public notice and a discretionary permit with conditions (sound, screening, emissions control); and (4) include enforcement provisions. Staff said proposed amendments will return to the board after the public process.
Technical and environmental notes: Planning staff said flaring capture rates and generator capture rates are both high but that crypto generation can be more efficient than open flaring because the heat/energy is put to productive use. Staff also noted neighbors’ potential concerns about noise, visual impact, and emissions and said mitigation language will be included in the draft amendment.
Next steps: Staff will prepare draft UDC language, schedule public hearings and include noise testing and muffler/stack standards in the draft. Commissioners asked staff to organize a site tour of a representative well and bring an FLIR or other emission evidence to illustrate current emissions for the new commissioner.
Ending: The board’s direction preserves operator options to avoid flaring at small wells while reserving discretion for the county to limit scale and protect neighbors through specific permit requirements.
