IRC— Professional Services Provided below is the detailed scope of work SCOPE OF WORK The scope of work within this proposal is divided into the following tasks. TASK 1: New Blower Flare Skid Design - Phase 1 As mentioned previously, the IRC county plans on replacing the existing blower flare skid with a new BFS which can produce the pressure required by the Heartland and IRED Facilities and providing them conditioned LFG which is free of moisture. It is our understanding that IRC and IRED and planning on jointly funding the engineering design, procurement, and construction of the new BFS. Currently, only the engineering design phase (Phase 1) of the project is being funded. Under this task, BGE will work with IRC, Heartland representatives to determine the ideal design for the integration of the BFS and controls communication between the LFG and the Heartland systems. This BFS will be designed to automatically adjust to account for changes at the Landfill and at Heartland's operations. To achieve this the design will likely require multiple sensors, modulating valves and utilization of a variable frequency drive (VFD) to maintain steady state operations and limit shutdowns on both systems. As mentioned above, the BFS design will include a new control panel which will be able to read inputs and control the necessary valves and blower settings at the desired frequency (for controlling the speed of the blowers). The BGE team will perform the following activities under this task. • Engage BCE's design engineering team to work with Heartland controls engineering team for the integration of the project; • Review design basis requirements from the Heartland team to specify a new high pressure blower flare skid; • Review Heartland's control strategy and provide input as necessary to protect IRC's interests and to successfully integrate the Heartland system with the new control panel. • Once the operational requirements for both systems are confirmed, prepare a design basis for all parties to review and approve prior to proceeding with the design; • Once the design basis has been approved, prepare detailed engineering design drawings in order to procure and construct a neer BFS; and • Under the design package of a new BFS, the following drawings will be provided o P&ID; o Process flow diagram including high pressure blowers; o Detailed mechanical drawings for the blower system; o Structural drawings, as necessary to support new installation; o Electrical drawings incorporating design for BFS equipment (aftercooler, chiller and heat exchangers); c A complete set of construction drawings for the procurement and construction of the new BFS; and * Controls integration and network drawings for the integration of the Heartland Facility.
