CATS Fuel Treating and Cleaning of Diesel Storage Tanks

The City of Charlotte is requesting proposals for fuel treating and cleaning of diesel storage tanks for the Charlotte Area Transit System (CATS) Facilities department, with proposals due August 24, 2026 at 3:00 p.m. EST through the Bonfire e-Procurement Portal.

The scope encompasses quarterly biocide treatments using Primrose MP8 Microbicide, annual fuel polishing with complete vacuum removal of water, sludge, and microbial organisms, and quarterly fuel sample testing to ASTM Standard D4176 across eight diesel underground storage tanks (USTs) located at two sites: 3145 South Tryon (three 40,000-gallon tanks and one 10,000-gallon tank) and 900 North Davidson (four 40,000-gallon tanks). The contractor must demonstrate a minimum of five years' experience in UST fuel sampling and biocide treatment. A 30-day warranty against microbial or biological reoccurrence is required.

The City has established the Charlotte Business Inclusion (CBI) Program to enhance participation of minority-owned, women-owned, and small business enterprises. Evaluation criteria are qualifications and experience, cost effectiveness and value, and acceptance of contract terms.

The estimated annual spend is $97,040. The initial contract term is three years with options to renew for up to two additional one-year terms. Pricing must remain firm for the duration of the contract unless otherwise specified. The contractor bears all costs for labor, materials, waste handling, transportation, disposal of non-hazardous and hazardous waste, and all required permits, certificates, and manifests. Commercial general liability insurance of at least $1 million per occurrence and workers' compensation insurance meeting North Carolina statutory requirements are mandatory.

A non-mandatory pre-proposal conference is scheduled for August 10, 2026 at 2:00 p.m. EST via Microsoft Teams. The evaluation committee may request interviews or presentations from selected proposers prior to award.
