PREVIOUS COUNCIL ACTION: None. BACKGROUND: Apex Companies, LLC and its subcontractor, GDI Drilling, are requesting permission to install 5 remediation wells within the Court Street right-of-way between 14th Street and 15th Street. The purpose of the remediation wells is to clean-up petroleum hydrocarbon-impacted soil and groundwater, associated with a gasoline release being regulated and managed by the Division of Oil and Public Safety (OPS) (Event lD 6531). Well installation is anticipated to take approximately five days. Appropriate traffic control will be utilized per a subcontracted traffic control plan. Concrete and/or asphalt coring, approximately 24-inches in diameter, will be used to access the boring locations. Potholing will be performed to clear boring locations of utilities to 6-feet below grade before drilling. Apex and GDI will then use hallow-stem augur technology to wells to approximately 15 feet below grade, per location. FINANCIAL IMPLICATIONS: None. BOARD/COMMISSION RECOMMENDATION: The Revocable Permit Review Committee recommends approval. STAKEHOLDER PROCESS: None. ALTERNATIVES: Denying the Resolution will prevent remediation of impacted soil and groundwater.
