This document is a comprehensive set of design plans and technical drawings for the Mid-Valley Sanitary Landfill Landfill Gas Flare Station project prepared by San Bernardino County Department of Public Works, Solid Waste Management Division. The project involves the construction of a new flare station facility located at 2390 N. Alder Avenue, Rialto, California 92377, designed to manage and safely dispose of landfill gas from Units 1-4 at the facility. The design includes installation of two low-NOx flare stacks (5,000 SCFM and 1,000 SCFM capacity), two gas handling skids (GHS-1 and GHS-2), two rotary screw compressors with associated equipment, a condensate management system with an 8,700-gallon poly storage tank, site improvements including grading and drainage infrastructure, a 40-foot by 40-foot pre-fabricated steel canopy structure, and ancillary equipment and controls. The project requires a Class "A" Contractor's License and encompasses 42 sheets of detailed civil, structural, mechanical, and electrical design drawings prepared under the supervision of registered professional engineers.

The design plans contain comprehensive technical specifications for concrete foundations, structural steel components, HDPE piping systems, electrical systems including a 2,000-amp switchgear, seismic design criteria consistent with the 2022 California Building Code, and various equipment anchorage requirements. The project includes demolition and salvage of the existing flare station and relocation of existing equipment including storage containers, operational trailers, and utility infrastructure. Construction details specify material requirements, reinforcement specifications, installation procedures, and special inspection requirements for structural elements, welding operations, and post-installed adhesive anchors. The site plan indicates the relocation of existing condensate sumps, compressed air lines, and interconnect piping systems, with field verification requirements for underground facilities. Equipment specifications identify manufacturers including PEI, Kaishan, ISCO Industries, Grundfos, and other suppliers, with major components including Lonestar Blower centrifugal blowers, condensate sump assemblies, and granular activated carbon treatment systems.
