Mr. Himanshu Mehta June 21, 2024 Page 2 • Install approx. 150 feet of 14 -inch SDR 17 header piping from the tie-in location to the flare station inlet pipe. • Tie-in at existing air -line pipe and install approx. 350 feet of 2 -inch SDR 9 air -line piping. HDPE air -line piping will daylight and connect to the flare skid air -line piping via a flanged connection. • Tie-in at existing condensate line and install approx. 350 feet of 2 -inch SDR 11 condensate piping. HDPE condensate piping will daylight and connect to the flare skid condensate lines via a flanged connection. • Install approx. 120 feet of 2 -inch and 4 -inch SDR 11 conduit piping for the RNG plant facility and leachate evaporator. • Install approx. 250 feet of 8 -inch SDR 11 pipe for the gas line to the leachate evaporator and pig launching station. The pig launching station will consist of a stainless-steel riser with a flange, two 8 -inch HDPE port valves and two valve boxes with lids. All internal fusion beads will be removed from the HDPE pipe and elbows will be sweeping. The 8 -inch pipe will connect to an existing 8 -inch pipe. • Install approx. 250 feet of 12 -inch SDR 11 pipe for the gas line to the future RNG facility pipeline and pig launching station. The pig launching station will consist of a stainless-steel riser with a flange, two 12 -inch HDPE port valves and two valve boxes with lids. All internal fusion beads will be removed from the HDPE pipe and elbows will be sweeping. The 12 -inch gas line will terminate with a blind flange since the gas line to the RNG facility is not currently installed. • All hardware will be stainless steel. Backing rings will be stainless steel where HDPE pipe meets with stainless steel pipe. Backing rings where HDPE pipe meets with HDPE pipe will be ductile iron. • HDPE pipe will be pressure tested at 20 psi for one hour. ASSUMPTIONS The scope of work is based on the following assumptions: • The scope of work or cost does not include the electrical installation scope of work. That scope of work is still under review and will be submitted in a separate proposal. • Concrete encasement of the valve boxes at both the 8 -inch and 12 -inch pig launching stations is not included in this scope of work. SCS -FS can provide concrete work at an additional cost. • Compaction testing will be performed by others. SCS -FS can provide compaction testing at an additional cost. • Pipe pressure testing will be performed at 20 psi for one hour. • SCS -FS does not provide performance guarantees or warranties on equipment that SCS -FS did not purchase. Warranties for equipment supplied by SCS -FS are based on the manufacturer's terms and conditions. • At a minimum, SCS -FS will have site access and permission to work Monday through Saturday from 7:00 AM to 7:00 PM. • The work area will be accessible and free of obstructions or other work activities performed by others that could delay the installation process. • SCS -FS may limit or restrict access to any and all traffic adjacent to the work area as needed. • Any additional drug testing or personnel background requirements to work for this project - those costs need to be passed through. Also, consider the time it takes to perform these checks/tests.
