Budget estimate

$200,000 – $1,000,000

No contract value is disclosed; however, typical municipal landfill remediation projects in Wyoming range from a few hundred thousand dollars to well over a million, depending on site size, soil conditions, and extent of pipeline work. Assuming a medium‑sized site with moderate pipeline work, a reasonable ballpark estimate would be $200,000–$1,000,000 for the full scope. Factors influencing the final amount include the acreage of the landfill, required earthwork volume, seed and mulch quantities, and any unforeseen site conditions.
