CASPER, WY — The Natrona County Commission is taking its fight to stop the Prism Logistics gravel mine to the Wyoming Supreme Court. The commission argues that a 2024 amendment to county zoning regulations, which prohibits mining in the MR‑1 “mountain residential” area at the base of Casper Mountain, is fully supported by state law and is essential to safeguard local families and the environment.
Legal arguments
Attorney William Phillip Schwartz, representing the commission, told the justices that the Wyoming legislature gave counties broad authority to protect local interests by regulating commercial and industrial operations. He emphasized that the amendment was adopted after extensive public input and reflects the will of Casper‑area residents who fear increased traffic, dust, and a drop in property values.
Prism’s position
Prism Logistics LLC and its CEO, Kyle True, are represented by Deborah Roden. Their argument rests on a separate chapter of state statutes that classifies gravel as a mineral under the jurisdiction of the state land board, which originally approved the leases in 2023 before many residents were aware of the project.
True has repeatedly told Oil City News that the proposed operation poses “more rhetorical fear than actual risk.” He notes that only about 1% of the 3,000‑acre surface area would be mined at any one time and that the project could generate tens of millions of dollars in severance‑tax royalties for the state while helping to lower construction costs in the Casper area.
Public opposition
Opponents, organized through the Casper Mountain Preservation Alliance, gathered roughly 20,000 petition signatures demanding a halt to the mine. Throughout 2025, they packed public hearings and attended meetings hosted by Prism to voice concerns about traffic, dust, property devaluation, and potential depletion of the local water table.
State land board actions
The state land board, overseen by Wyoming’s five top elected officials, voted 3‑1 and later 3‑2 in the summer of 2025 not to renew the two sets of leases issued in 2023. The board cited a constitutional mandate to monetize state‑owned land to fund schools, but also recognized the growing local opposition.
Prism sued both the Natrona County Commission and the state land board, winning both cases in Natrona County District Court. The board appealed, bringing the matter before the Wyoming Supreme Court for oral arguments last month. Both cases now await a final decision from the justices.
Why the amendment matters to families
For many Casper residents, the amendment represents a concrete step to protect the quality of life for families living near the mountain. By keeping large‑scale mining out of the residential zone, the commission aims to preserve clean air, maintain property values, and ensure that the water table remains stable for future generations.
“Our community’s health and safety come first,” Schwartz said. “The amendment is not about opposing industry; it’s about exercising the authority granted to us to protect our neighbors and our children.”
Looking ahead
The Wyoming Supreme Court’s ruling will set an important precedent for how counties can use zoning tools to balance economic development with local quality‑of‑life concerns. If the justices uphold the amendment, Natrona County will retain its ability to block similar projects that threaten residential areas. If the court overturns the amendment, the commission may need to seek alternative protective measures, such as state‑level legislation or additional local ordinances.
Regardless of the outcome, the case underscores the ongoing tension between state‑wide resource development goals and the desire of local communities to preserve their neighborhoods, families, and natural surroundings.
