If the testing or other reliable information indicates the presence of contaminated soil, and UDEQ concludes that such soils cannot be stabilized in place and must be remediated as part of the development project, as a prerequisite to receiving initial development approval from the city, the developer shall contact UDEQ, and shall develop and complete a UDEQ prescribed voluntary cleanup plan for contaminated soil remediation. Prior to receiving final occupancy or development use approval from the city for the project, the developer shall submit to the city a state certificate of completion pursuant to Utah Code Annotated section 19-8-101 et seq., and any amendments thereto. (2001 Code § 42-1-102)
