About this file

Written by GovTribe AI · Sep 24, 2025

These construction plans, prepared by Environmental Consultants SCS Engineers, detail the Cell 4B 2022 Construction project for the City of Tucson Environmental & General Services Department at the Los Reales Landfill located in Tucson, Arizona. The project involves constructing a new landfill cell (Cell 4B) which includes demolition of existing structures, grading and infrastructure construction, installation of a leachate collection system, process water tank installation, and protective cover placement. The work will take place at 7161 S Craycroft Road and involves detailed engineering specifications for liner systems, drainage infrastructure, road construction, and associated electrical systems.

The project requires careful management of an active landfill environment, with specific safety precautions regarding landfill gas (LFG) and potential hazardous conditions. The construction includes technical specifications for subgrade preparation, geosynthetic liner installation, leachate collection systems, stormwater management, and infrastructure components. Electrical work involves installing new disconnect switches, pumps, conduit systems, and lighting. The plans emphasize precise engineering requirements, including slope stabilization, liner anchoring, and compliance with environmental and safety regulations. The project appears to be funded by the City of Tucson and will expand the existing landfill's waste management capacity through the construction of Cell 4B.

NOTE TO CONTRACTOR:

THE CONTRACTOR IS DULY ADVISED THAT CONSTRUCTION IS BEING PERFORMED AT A SOLID WASTE FACILITY. THE

PRESENCE OF LANDFILL GAS (LFG), WHICH CONSISTS PRIMARILY OF METHANE, CARBON DIOXIDE, HYDROGEN

SULFIDE, AND OTHER GASES COULD BE PRESENT. THE PRESENCE OF LFG CAN CREATE A HAZARDOUS ENVIRONMENT

WITH THE POTENTIAL FOR BOTH COMBUSTION/EXPLOSION AT CONCENTRATIONS BETWEEN 5% AND 15% METHANE, BY

VOLUME. THE CONTRACTOR IS ADVISED TO TAKE EXTRA PRECAUTIONS DURING CONSTRUCTION ACTIVITIES

INCLUDING WELDING OR OTHER ACTIVITIES THAT COULD GENERATE A SPARK OR HEAT. THE CONTRACTOR IS ADVISED

TO MONITOR METHANE CONCENTRATIONS IN THE WORK AREA AND ADHERE TO THE HEALTH AND SAFETY

REQUIREMENTS.
