The much-maligned company exploring a potential gravel mining operation at the base of Casper Mountain is moving forward with its highly controversial plans that nearby residents and recreationalists say would spoil the area, while offering a long list of commitments in hopes to assuage public concerns.

Prism Logistics LLC will consider drilling deep water wells should mining interrupt existing wells in the area, according to a two-page letter that Prism Manager Kyle True issued Thursday. The company also promises to limit the footprint of active mining operations and ask the state for permission to move its crushing operation away from the area to reduce dust and noise.

“We believe that we can responsibly develop this resource taking into account concerns of locals, develop significant economic activity in the area and leave behind an improved ecosystem with more diversity than currently exists,” True said.

The Casper Mountain Preservation Alliance, which represents opponents of the project, said it wouldn’t comment on Prism’s letter or the commitments it has offered. However, the organization says it would rather see Prism abandon the project or state and local officials block it.

“We hope that the mine doesn’t occur,” alliance organizer Carolyn Griffith told WyoFile. “We’re worried about our water, and we’re also worried about the road and trucks.”

Responding to opposition, as well as criticism that it approved gravel mining exploration leases in the area without public notice, the Wyoming Board of Land Commissioners earlier this month ordered staff to investigate whether the agency could negotiate with Prism to voluntarily “relinquish” its leases and potentially compensate the company. But so far, the agency has not offered further details, nor has it reached out to Prism about a potential negotiation, according to True.

Meantime, the company has applied for a limited mining operation permit with the Wyoming Department of Environmental Quality — the next step in potentially commencing operations on the state trust lands surrounded by hundreds of homes just west of Casper. 

Prism commitments

Homes and grazing operations in the area rely on dozens of shallow water wells, which opponents say are likely to be impacted by mining in the sensitive watershed that flows into the nearby North Platte River.

Though True said he doubts the extent of potential interference envisioned by locals, Prism will consider donating to a homeowners’ association one or two deep water wells that tap a more reliable source of water. “This would provide a much better supply of water than the shallow water supply currently used by area residents,” True wrote in the April 18 letter, which was sent to state and local officials, as well as several lawmakers.

In addition to potentially drilling replacement water wells and moving its crushing operation to another location, Prism also promised to “maintain” or improve roads in the area. True also offered several ideas for potential post-mining recreational improvements to the state lands, including fishing ponds, a polo field and planting trees.

“These are not our decisions particularly to make, but the possibilities with proper planning are significant, and this could become an even more enjoyable piece of state land than it is today,” True wrote.

By the book

Casper-based Prism Logistics primarily mines and processes sand and gravel for construction and road building, and currently operates more than a dozen mining operations in the state, according to the company. 

The company plays a vital economic role in helping to support construction in the state, True has said, and he sees great “economic” potential in the gravel resource in the Coates Road area west of Casper.

So far, the firm has played by the book in pursuit of the effort, according to state and local governments.

Until nearby residents learned about the project, there was no public outcry over permitting such operations or granting leases on state lands. The Office of State Lands and Investments has since come under fire, however, for not notifying nearby residents before the board unanimously approved “exploration leases” on several state land sections last year.

“I think there needs to be a little more scrutiny before these things get put on [the Office of State Lands and Investments’] consent list,” Rep. Steve Harshman (R-Casper) told WyoFile in March. “There’s got to be a way for more public notice and debate.”

Opponents have also taken aim at the state’s limited mining operation program, which essentially rubber-stamps mines smaller than 15 acres without requiring a full slate of environmental analysis.

For its part, Prism has suggested a series of public meetings — which are not required under existing law — after it drafts a mining plan. 

Natrona County commissioners have said they will consider exercising a “conditional use permit” should a mining proposal come before the county. Although counties sometimes exert regulatory stipulations on some industrial operations, state officials have said they will not cede authority over state lands, which are managed as a “trust” to support schools.

WyoFile's goal is to provide readers with information and ideas that foster constructive conversations about the issues and opportunities our communities face. One small piece of how we do that is by offering a space below each story for readers to share perspectives, experiences and insights. For this to work, we need your help.

What we're looking for: 

  • Your real name — first and last. 
  • Direct responses to the article. Tell us how your experience relates to the story.
  • The truth. Share factual information that adds context to the reporting.
  • Thoughtful answers to questions raised by the reporting or other commenters.
  • Tips that could advance our reporting on the topic.
  • No more than three comments per story, including replies. 

What we block from our comments section, when we see it:

  • Pseudonyms. WyoFile stands behind everything we publish, and we expect commenters to do the same by using their real name.
  • Comments that are not directly relevant to the article. 
  • Demonstrably false claims, what-about-isms, references to debunked lines of rhetoric, professional political talking points or links to sites trafficking in misinformation.
  • Personal attacks, profanity, discriminatory language or threats.
  • Arguments with other commenters.

Other important things to know: 

  • Appearing in WyoFile’s comments section is a privilege, not a right or entitlement. 
  • We’re a small team and our first priority is reporting. Depending on what’s going on, comments may be moderated 24 to 48 hours from when they’re submitted — or even later. If you comment in the evening or on the weekend, please be patient. We’ll get to it when we’re back in the office.
  • We’re not interested in managing squeaky wheels, and even if we wanted to, we don't have time to address every single commenter’s grievance. 
  • Try as we might, we will make mistakes. We’ll fail to catch aliases, mistakenly allow folks to exceed the comment limit and occasionally miss false statements. If that’s going to upset you, it’s probably best to just stick with our journalism and avoid the comments section.
  • We don’t mediate disputes between commenters. If you have concerns about another commenter, please don’t bring them to us.

The bottom line:

If you repeatedly push the boundaries, make unreasonable demands, get caught lying or generally cause trouble, we will stop approving your comments — maybe forever. Such moderation decisions are not negotiable or subject to explanation. If civil and constructive conversation is not your goal, then our comments section is not for you.

  1. This will not be a small mining operation. The Limited use permit is just so he can get his foot in the door. I this permit is allowed he will start with 15 acres of mining and the go to 30 acres. After that he has stated that he will apply for a large mining permit. Please keep in mind that he has a total of 3200 acres at the Casper Mountain location that he can mine. He is trying to create a small footprint to get it all started. 3200 acres is no small footprint. If he mines the entire area, it could take 50+ years to do so and that is no impact on our community?

  2. Ol Chuck did it to you again. He took voting rights away from you and he approved this boondoggle that will devalue your home. Adding insult to injury, he’s from California.

  3. Polo field. A polo field?
    Just what most comes to mind as recreation for most Casper residents. True does seem to have our interests at top of his priorities.

  4. We have a “limited mine” in our small community which is dotted with old ranches, an elementary school and a small subdivision close by – and downwind of this quarry mining sherman granite. The community did not want it, it should not be here by all accounts. Close neighbors have had issues with burning eyes after blasting and some have lost water in their wells. We are still trying to get it shut down. Once they have their foot in the door – be very careful they cannot get a permit to increase operations.

  5. Kyle True says, “ this could become an even more enjoyable piece of state land than it is today.” That’s impossible if he removes everything that makes it enjoyable! I guess with only dollar signs in his eyes, it will be more enjoyable for him to see that beautiful land turn into a stack of money, at Casper’s expense.
