About this file
This is a Well Schedule document for the 2026 GCCS (Gas Collection and Control System) Construction project at Hoffman Road Landfill, prepared by Tetra Tech for the City of Toledo, Ohio. The document specifies technical specifications and survey data for eight groundwater monitoring wells to be installed at the landfill site, including well identifications (GE 44R5, GE 57R1, GE 59R3, GE 83R1, GE 84R1, GE 54R1, and GE 55R2), their geographic coordinates in feet, ground surface elevations in feet MSL, borehole depths, waste depth measurements, perforation intervals, and solid casing requirements. Ground surface elevations were obtained from a survey performed by DroneView Technologies on November 18, 2025, and current elevations must be re-surveyed prior to the start of drilling operations. The well schedule requires a minimum 15-foot separation between the base of the borehole and the top of the base liner system, with solid casing extending 15 feet below grade unless otherwise noted. Well locations may be relocated during construction to accommodate field conditions, requiring re-survey and updated schedule approval by all parties before drilling commences.
The document includes acknowledgment requirements for the Design Engineer, QA/QC Reviewer, CQA Inspector, and Driller, and explicitly prohibits drilling activities from beginning without obtaining all required signatures. The related City of Toledo bid solicitation requires contractors to submit bids exclusively through the PlanetBids portal and provide supporting documentation including a preliminary construction schedule, three project references for similar work, equipment and labor rates, a signed contract, tax exemption certificate, and a bid guaranty in the form of a cashier's check or bid bond. Bid prices must be stated to two decimal places with only one price per line item accepted. Tetra Tech assumes no liability for delays resulting from confirmation and final approval of well drilling locations.

DEPTH OF WASTE IS ASSUMED TO BE THE MATHEMATICAL DIFFERENCE BETWEEN THE GROUND SURFACE AT THE TIME OF SURVEY AND THE TOP OF THE BASE LINER
SYSTEM.
WELL LOCATIONS MAY BE RELOCATED DURING CONSTRUCTION TO ACCOMMODATE FIELD CONDITIONS. ALL CHANGES MUST BE RE-SURVEYED AND AN UPDATED WELL SCHEDULE FOR THAT LOCATION APPROVED BY ALL PARTIES PRIOR TO THE COMMENCEMENT OF DRILLING.
