Adams County approves 26‑well Bennett DPAD at Manila with extensive monitoring and mitigation conditions

The Adams County Board of County Commissioners approved OGF 20251, the Bennett DPAD at Manila, on Oct. 28, authorizing up to 26 horizontal wells and a production facility on a 143.7‑acre parcel in agriculture zoning. The vote was 5–0.

Staff summary and waivers

Greg Dean, Adams County oil and gas administrator, told the board the applicant, Crestone Peak Resources (a subsidiary of Civitas Resources), will disturb up to 23 acres during drilling and reclamation will reduce the permanent disturbance to about 7.4 acres after completion. The site sits adjacent to an existing crude‑oil transfer facility (Bennett Station), and much of the parcel lies inside the CASP (Colorado Air and Space Port) airport restriction zones, which restrict future occupiable development.

Because of measured parcel distances and how county setbacks are measured to parcel lines, two waivers were before the board: a waiver from the 2,000‑foot setback to environmentally sensitive areas (wetlands) and a waiver from the 2,000‑foot residential setback. Dean said the applicant obtained Colorado Parks and Wildlife (CPW) concurrence for the wetlands and had one tenant within 1,500 feet who provided informed consent; one adjacent landowner opposed the project and was selling the property. Staff recommended the waivers because they found “substantially equivalent protections” from proposed mitigation measures.

Mitigation and monitoring conditions

The board required multiple enforceable conditions of approval. Key measures include:

- Electric drilling rigs during drilling operations and a requirement to halt drilling if grid power is unavailable. - Temporary 32‑foot sound walls around the pad during drilling and completion to reduce noise. - Continuous, county‑approved air monitoring for the life of the wells, including multiple real‑time sensors, a meteorological station, and automatic SUMA canister sampling when thresholds are exceeded; data sharing with the county and the state is required and third‑party laboratory analysis will follow triggered samples. - Limits on on‑site liquid hydrocarbon storage (no permanent crude oil storage; only two produced‑water tanks permitted) and secondary/tertiary containment meeting county and state standards. - A traffic‑impact fee payable prior to construction; the applicant submitted an independent fee assessment that reduced the fee from a theoretical $510,951 to $120,586 based on localized impacts and state statute guidance limiting fees to impacts directly tied to the development. - If the pipeline takeaway is unavailable, wells must be shut in; the operator may not truck crude off‑site or store it permanently on location. - If the operator elects to conduct on‑site produced‑water recycling during completions, it must follow an approved produced‑water recycling plan with emissions controls and closed systems; the county explicitly reviewed that plan though state‑level produced‑water rules take effect in 2026.

Inspections and enforcement

Dean and engineering staff detailed an inspection regime that includes weekly site‑status inspections during active operations and at least annual inspections of active wells. The county uses gas‑imaging cameras as part of inspections and requires regular calibration and data review of air monitors; triggered SUMA canisters are sampled and analyzed by an approved laboratory (typical turnaround cited as roughly two to three weeks for lab results), and the county receives near‑real‑time sensor data for early detection and response.

Applicant and alternatives

Crestone representatives said they selected the pad to collocate with existing midstream infrastructure to minimize new surface disturbance and pipeline mileage. Crestone presented seven alternative locations that they said would have required additional pads, more pipeline infrastructure or greater impacts to residences or high‑priority habitat. Crestone pledged multiple BMPs — enclosed systems, sand handling with dust controls, lined containment under equipment, and community outreach including quarterly neighborhood meetings and pre‑construction notices to residents within a mile.

Board action and reasons

Commissioners asked detailed questions about noise, monitoring cadence, produced‑water recycling and future land use. Several commissioners noted the parcel’s CASP restriction zones and concluded that future residential or commercial occupiable development is constrained, reducing the risk of future land‑use conflicts. After discussion, the board approved the permit with findings, two waivers, multiple conditions precedent and conditions of approval, and a three‑year permit term requiring the operator to drill and complete all wells within three years or return for reauthorization. The motion passed 5–0.

Why this matters: The approval allows a major oil‑and‑gas operation within Adams County but includes an extensive set of monitoring and mitigation conditions the board and staff said are intended to protect air quality, limit noise and control runoff and traffic impacts. The conditions also bind the operator to county‑level data sharing and inspections that go beyond some state baseline requirements.

What happens next: Provided the applicant pays required fees and meets conditions precedent, construction may begin; the first phase of drilling and completions is projected across 2025–2027 and continuous air monitoring and community outreach are required for the life of the wells.
