Landfill gas, air quality and design consulting services at county landfills.

Greenville County, South Carolina is issuing Request for Proposals #26092 for Landfill Gas, Air Quality and Design Consulting Services to provide specialized environmental consulting across three county-operated landfills: Twin Chimneys (active facility), Blackberry Valley (closed facility with gas collection infrastructure), and Enoree Landfill (closed facility with two phases). The County seeks qualified firms to deliver landfill gas and air quality data evaluation, reporting, design, permitting, and regulatory consulting services in compliance with the County's Title V Operating Permit, Greenhouse Gas Reporting Rule, and applicable EPA regulations. Key deliverables include semi-annual Title V reports for Twin Chimneys, annual Title V compliance certifications, greenhouse gas reports, and miscellaneous consultation services, with all final reports due three days before submission deadlines and draft reports due fourteen days prior. Qualified respondents must demonstrate a minimum of ten years of experience in landfill gas and air quality data evaluation and provide examples of similar work for at least four landfills completed within the past four years in South Carolina. Proposals will be evaluated equally across six criteria: responsiveness (16.7%), experience with similar projects (16.7%), cost (16.7%), references (16.7%), contractor qualifications (16.7%), and methodology (16.7%). The proposal submission deadline is April 1, 2026, at 3:00 PM via the County's online procurement portal; questions must be submitted by March 11, 2026, at 5:00 PM. Award is anticipated for April 24, 2026, followed by contract negotiations through June 30, 2026, with a Notice to Proceed issued by June 30, 2026.

The RFP does not indicate any set-aside designations or restrictions limiting participation to specific types of organizations or disadvantaged enterprises. No incumbent vendor or current contractor is identified in the procurement documents. Contractors must obtain and maintain Comprehensive General Liability insurance of $1,000,000 per occurrence/$2,000,000 aggregate, Automobile Liability coverage of $1,000,000 combined single limit, and statutory Worker's Compensation insurance, with the County named as an additional insured on all policies except Worker's Compensation and Professional Errors and Omissions; no bonding is required. Pricing must be structured based on thirty-day payment terms and presented as estimated costs per anticipated deliverable with hourly rates for additional services, including applicable annual inflation rates. The RFP does not specify an explicit contract award value or budget range, though compensation will be determined based on the specific project requirements through the contractor's pricing proposal. The contract term is not explicitly specified in the available documents, though the Sample Services Agreement template indicates provisions for an initial term with options to extend for up to four additional one-year renewal terms with thirty days' advance written notice.
