NIGP 92551: Hazardous Waste Engineering Services (incl. Remedial Investigations and Feasibility Studies for Waste Sites)

NIGP 92551 Hazardous Waste Engineering Services (including Remedial Investigations and Feasibility Studies for Waste Sites), an Item code, encompasses environmental site assessment, remediation design, and compliance documentation services that state and local governments procure for contaminated property evaluation and cleanup planning. Recent state and local solicitations under this code reflect a mix of remedial investigation and design work, hazardous waste disposal logistics, and environmental compliance consulting across water infrastructure, brownfield assessment, and underground storage tank incidents. Issuing bodies soliciting under the code include state environmental departments (New Jersey Department of Environmental Protection, North Carolina Department of Environmental Quality), county governments (Jefferson County Kentucky, Marion County Florida, Madison County Georgia), cities (Columbus Georgia, Pembroke Georgia, Wichita Kansas), and special-purpose districts (Great Lakes Water Authority, Seminole County). Repeat buyers include Georgia jurisdictions (multiple RFPs from GDOT and city/county partners) and Florida entities managing water and waste infrastructure remediation.

Recent opportunities span the full remedial cycle. The New Jersey Department of Environmental Protection posted RFQ T2621 for remedial investigation and design services with comprehensive hazard assessment, quality assurance project plan development, and Licensed Site Remediation Professional staffing (quote deadline November 20, 2026). Jefferson County Kentucky solicited environmental site remediation for the Drum Site in Fairdale involving excavation of VOC-, SVOC-, and PCB-contaminated soils (proposals due July 13, 2026). The Consolidated Government of Columbus Georgia sought environmental consulting under an EPA Multipurpose Brownfield Grant covering Phase I and II environmental site assessments for up to 14 properties, remedial design, and Bradley Circle Landfill cleanup oversight (proposals due August 21, 2026). Marion County Florida issued ITB 26B-101 for hazardous waste collection, lab packaging, transportation, and disposal through EPA-permitted TSD facilities, with an estimated baseline of four household hazardous waste events annually over three years (bids due July 16, 2026). Geographic activity concentrates in the Southeast (Georgia, Florida, Kentucky, North Carolina, South Carolina) and Mid-Atlantic (New Jersey), with secondary activity in the Midwest (Michigan Great Lakes Water Authority) and Southwest (Arizona Maricopa County Community College District). The code remains active across municipal water remediation, brownfield redevelopment, and routine hazardous waste stream management, with moderate responsiveness from regional engineering and environmental consulting firms.
