Pennington County delays decision on Box Elder-area gravel pit after hours of public testimony

Pennington County commissioners on July 1 continued action on a proposed mining permit for 63 Industries LLC, delaying a final decision until an on-site visit and a later hearing so the board could weigh technical, infrastructure and land-use concerns raised by residents, the city of Box Elder and the Douglas School District.

The proposal would allow mining on the northeast quarter of Section 16 (the applicant estimates roughly 160 acres within a 640-acre parcel), with staged operations and a reclamation plan presented by applicant representatives. Planning staff recommended denial, citing incompatibility with existing and planned land uses, uncertain water impacts and inadequate road access under county road standards.

Why it matters: Commissioners heard repeated concerns about increased truck traffic on narrow local roads, potential sediment or groundwater impacts, and the effect of a nearby industrial operation on planned residential growth for Box Elder and on property values. The county must balance landowner property rights, state mining permits and the county comprehensive plan and road standards.

Planning staff summarized the technical issues at length. A planner told the board the application lacked an environmental assessment supporting claims that surface or groundwater would not be affected and that the proposed accesses (150th Avenue and 220th Street) do not meet Pennington County Ordinance 14 road-width standards for commercial/industrial traffic. The planner also noted a floodplain and wetlands inside the larger section and said an 18-inch culvert the applicant proposed would require engineered verification.

Douglas School District operations director Tim Kosters told commissioners the district opposes the permit because of safety and traffic concerns near student routes and a planned elementary site. Box Elder Mayor Larry Larson said the city council unanimously opposed the project, and submitted an estimate that reduced property values could cost local taxing entities about $92,000 a year in lost revenue if nearby home assessments fell.

Applicant representatives said they hold a state mining permit for the described quarter and described a phased operation they said would disturb small acreages at a time (staff described phased activity of roughly 10 to 15 acres). A representative said the permit term listed to 2045 reflected state permitting practice and that the operatorand the landownerhave a shorter commercial agreement (applicant representatives said four years) for the expected economically recoverable material. The applicant also said using a closer pit would reduce haul distances, lowering truck miles on county roads compared with hauling from existing pits farther away.

Several residents described the siteone called it within "a half-mile" of existing subdivisionsand urged the board to deny the permit, citing dust, noise, traffic, safety for pedestrians and schoolchildren, and expected negative impacts to future residential development and commercial recruitment.

At the end of the hearing the board debated whether commissioners should visit the site before deciding. Commissioners expressed differing views: some said the planning record and the completed staff analysis were sufficient to deny, while others said a site visit and further study would clarify topography, exact boundaries of disturbance and whether conditions could mitigate impacts.

The board voted 3-2 to continue the matter and schedule an official, noticed site visit and follow-up hearing for August 5 so the full commission can view the parcel and additional materials. Commissioners asked planning staff and the state's attorney to prepare notice and advise on meeting requirements for an on-site visit and any specific evidence the board should review before the next hearing.

Next steps: The county set a continued hearing and a publicly noticed site visit for August 5. Planning staff and the applicant were directed to supply outstanding technical materials (stormwater and erosion control details, the state NLI responses, a reclamation surety estimate and any additional groundwater or environmental analysis) in advance of the August hearing.
