The Colorado Department of Public Health and Environment is seeking competitive bids to conduct Five-Year Reviews for five Superfund sites under EPA CERCLA requirements, with field work to be completed in 2026 and final reports due by early 2027. The sites include Lowry Landfill, Smuggler Mountain, Chemical Sales Co., Captain Jack Mill, and California Gulch, each with specific statutory deadlines ranging from January to September 2027. Proposals must demonstrate prior experience conducting Five-Year Reviews on at least two of these five specific sites, a mandatory pass/fail criterion. The total contract value is capped at $370,000, with required line-item budget breakdowns for each site, inclusive of costs for a Quality Assurance Project Plan, Health and Safety Plan, and all other deliverables. The solicitation follows an Invitation for Bid format and is expected to be awarded on a Lowest Price Technically Acceptable basis. Proposals must include the official Budget Template and align with the Draft Statement of Work, submitting all materials by the July 27, 2026 deadline to the Colorado CDPHE office in Denver. No electronic submission portal is specified, implying physical delivery is required. All work is performed on-site at the five Superfund locations, and acceptance occurs through official review by the contracting office. The sole point of contact for all inquiries and submissions is Kristi Gamble at kristi.gamble@state.co.us. Modification #1 adds Addendum 1 Questions and Responses, clarifying budget allocation and experience requirements, with no other changes to the original solicitation.
