▸ Full text (the legislation as adopted)

The City of Portland ordains. Section 1. The Council finds: The Bureau of Environmental Services (BES) needs to procure a contractor to replace the Digester Gas Combustion system. The current system is undersized even with temporary measures and is past its useful life. The Digester Gas Combustion System is one of the ways that the gases created in the digesters are processed. The system uses flares to burn the gases that were not processed by other means and is significantly safer than venting the gases directly into the air. While the current system has a 2 nd temporary flare to expand the capacity of the combustion system, it still does not have the capacity to process all the gas created by the digesters. This project will replace both the current and temporary flares with two new flares that have expanded capacity able to handle the anticipated gas volume. This system runs 24 hours a day, 7 days a week, to process the gases created in the digesters safely. If the current system were to fail, it would create a public safety hazard along with jeopardizing regulatory compliance. The established cost is $5,600,000. The level of confidence is high. Funds are available in the Sewer System Operating Fund, FY2024-25 Budget, Bureau of Environmental Services, WBS Element E10649. NOW, THEREFORE, the Council directs: The Chief Procurement Officer is authorized to conduct a competitive solicitation process for the lowest responsive and responsible bidder in accordance with Chapter 5.34 of the Portland City Code. Upon the Council’s acceptance of the Chief Procurement Officer’s report recommending the lowest responsive and responsible bidder, the Chief Procurement Officer is authorized to execute a contract, provided the contract has been approved as to form by the City Attorney’s office. The Mayor and Auditor are hereby authorized to pay for the contract from the Sewer System Operating Fund Budget when demand is presented and approved by the proper authority.
