All questions requesting interpretation or clarity to the Contract Documents must be submitted in writing to the Director of Public Works, 2515 Valley Drive, Bristol, Virginia 24201, or by email at jacob.chandler@bristolva.org The City of Bristol, Virginia (City) is requesting bids from qualified contractors to perform landfill gas (LFG) collection and control system (GCCS) operation, monitoring, and maintenance (OM&M) services for the Citys Integrated Solid Waste Management Facility (ISWMF). The project shall be performed in accordance with criteria set forth in the contract documents which shall include these documents. This document contains general information relating to the evaluation process, selection criteria, and mandatory requirements that must be addressed for a bid to receive consideration. The City owns and operates an ISWMF that includes a municipal solid waste landfill constructed in a former quarry pit. The GCCS is installed for the primary purpose of controlling emissions in accordance with air quality regulations, controlling LFG migration and odors, and providing LFG to fuel a LFG to energy plant or a utility flare. The GCCS is critical for removing perched liquids, gases, and heat in order to manage elevated temperature conditions in the quarry landfill. The GCCS conveys LFG to a main blower/flare station consisting of utility flares, blowers, a moisture separator, and ancillary devices. The GCCS incorporates a variety of gas collection devices to meet LFG management goals for the facility and the requirements of the new Source Performance Standards/Emission Guidelines (NSPS/EG) and the National Emissions Standards for Hazardous Air Pollutants (NESHAP). The GCCS must be monitored and balanced, as necessary, on at least a monthly basis. However, more frequent monitoring and inspection of the LFG system is warranted due to the malodorous conditions being experienced at the site as well as the potential elevated temperature conditions. As part of the GCCS operation, various non-routine operations and maintenance services may be required, such as, but not limited to, LFG wellhead apparatus modifications and repairs, liquid management system and pump maintenance, investigation and repair of blower/flare station issues, moving and re-grading of above ground pipes as a result of landfill settlement, or other tasks as directed. This project is to perform OM&M services on the LFG system at the Citys ISWMF located in Bristol, Virginia. The ISWMF consists of various municipal solid waste management units including three (3) solid waste landfills. It is anticipated that in order to effectively maintain GCCS operation and to provide services in a safe and efficient manner, a full-time crew of two field personnel led by an experienced on-site Project Manager will need to be dedicated to the ISWMF. The team is to meet with the City regularly (at least bi-weekly, and more often as needed) to discuss current operating conditions, issues and progress, and to evaluate, plan, and schedule activities necessary to operate and maintain the system. This will include, but not be limited to: Confirm proper operation of the system components.
Confirm/initiate appropriate measures required to maintain regulatory compliance.
Provide recommendations to improve system operation.
Set LFG flow targets and other operational objectives.
Plan and schedule O&M goals and activities. The LFG collection system currently consists of 60 wells, approximately 18 of which are equipped with dedicated pumps to keep them dewatered to enhance gas collection. This project is for monthly services from January 1, 2023 to January 1, 2026.
