The Wyoming Department of Environmental Quality has identified the source of a costly gasoline seep that leached an unknown quantity of fuel into the Middle Fork of the Popo Agie River in Lander.

In a Notice of Violation filed with Maverick Inc. Friday afternoon, DEQ accused the gas station operator of failing “to make the necessary repairs to prevent overfilling the unleaded gasoline tanks,” buried near the banks of the river. In an accompanying press release the agency wrote that “Maverik overfilled one of the gasoline underground storage tanks at the facility. The overfill resulted in the release of gasoline that impacted the Popo Agie River.”

A “Red Tag Order” accompanied the NOV, barring Maverick from selling or receiving fuel at its Lander location until the problem is resolved.

The Lander Fire Department, responding to reports of a strong gasoline odor, discovered an oily sheen on the river near its Main Street underpass immediately downstream of a Maverick gas station April 2.

The EPA arrived onscene April 4 to begin trying to stanch the flow of contaminants into the navigable waterway — an ongoing endeavor that’s been hampered by fire and inclement weather. Responders from the federal agency are racing to complete a concrete barrier wall, and backfill the excavated bank, before spring runoff arrives.

The Notice of Violation notes that because it resulted from an overfill, the spill “is not eligible for cleanup under the Corrective Action Account,” and that DEQ can “seek cost recovery.” The DEQ does not yet have an estimate of how much the response has cost state and federal taxpayers, according to agency spokesman Keith Guille.

The NOV is not a “ticket”, Guille said, but rather an allegation — the agency’s official notice to the public, and to the accused violator, of what it believes caused the problem. It is the first step in what typically proceeds as a negotiation, he said. Maverick can respond with an explanation and evidence of its own. Required corrective actions, cost recovery, fines and all other elements leading to a Notice of Compliance resolution are all likewise subject to negotiation. Such discussions can land in court, Guille said, but rarely do.

WyoFile did not receive a response to requests for comment from Maverick by press time.

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. There is more to this story as all these tanks are required to have overfill protections including alarms and shut off valves to prevent this type of spill. Someone knew something at the time of the spill. So either the fuel delivery operator and/or the station had to know immediately that there was a release and no one reported it, hoping it would go away. The lack of candor increased the environmental degradation and should end up costing the operator and/or the fuel delivery company to pay the bill, but there should be some punitive fines and firings for the coverup.

  2. No negotiation. If Maverick is the cause of the contamination, they should bear the total cost of all expenses related to discovery, isolation, remediation, and reclamation, plus all applicable fines. I like to do business with Maverick, but they need to shoulder the responsibility for running a good and sound business
