About the company
Clean Harbors Environmental Services Inc., doing business as Clean Harbors Of Connecticut Inc., delivers hazardous waste removal, treatment, transportation, storage, and disposal services to federal agencies as a prime contractor (99% of awards) operating across full-and-open competition with no SBA set-aside designations. The vendor is a large for-profit environmental services company headquartered in Norwell, Massachusetts, and is a subsidiary of Clean Harbors Environmental Services Incorporated.
Clean Harbors' federal footprint is heavily concentrated with the Defense Logistics Agency Disposition Services, which accounts for 9,760 awards (79% of the vendor's award count) and $410.7 million combined potential value (35% of total) across five primary indefinite delivery contracts—SP450022D0009 (1,851 task orders, $15.8 million), SP450020D0015 (1,101 task orders, $12.1 million), SP450022D0011 (980 task orders, $9.5 million), SP450017D0008 (958 task orders, $7.3 million), and SP450008D0019 (742 task orders, $10 million). Beyond DLA Disposition Services, the vendor serves the Department of Homeland Security U.S. Coast Guard (378 awards, $46.9 million), the Department of the Treasury Bureau of Engraving and Printing (73 awards, $51.8 million), the Department of Agriculture Animal and Plant Health Inspection Service Veterinary Services (76 awards, $38.5 million), and the Department of the Navy Naval Sea Systems Command (224 awards, $21.2 million). These five customer concentrations represent 87% of total awards and 49% of combined potential value. The breadth across 209 distinct federal agencies reflects Clean Harbors' commodity-like standing in hazardous waste and environmental remediation work—individual orders are typically small-dollar delivery orders and blanket purchase agreement calls with firm fixed pricing.
Representative recent work spans hazardous and non-hazardous waste management across federal locations. On July 7, 2026, the Environmental Protection Agency established a single-award BPA ceiling of $815,187 for chemical and hazardous waste disposal services under the GSA Multiple Award Schedule, with the first call valued at $334,055.23 for Cincinnati-based services through July 6, 2029. On May 1, 2026, Veterans Integrated Service Network 12 awarded a five-year indefinite-delivery contract ceiling of $548,884.02 for hazardous waste collection at the Clement J. Zablocki VA Medical Center in Milwaukee, Wisconsin, running through April 30, 2031. Clean Harbors also holds active positions on the GSA Multiple Award Schedule with labor rates spanning $89.51 to $159.61 hourly for roles from foreman through emergency-response supervisor, requiring high school education with no security-cleared labor offerings. Recent DLA Disposition Services delivery orders include hazardous waste management at Hill Air Force Base, Lewis-McChord, Fort Richardson (Anchorage), San Diego, and NAS Point Mugu; hazardous waste testing and analysis; chemical and liquid handling (including PFAS testing and disposal); laboratory pack services; and oxygen canister and PFAS fire-extinguisher disposal. The U.S. Coast Guard places time-and-materials delivery orders for oil spill and hazardous chemical incident response labor, materials, and equipment, with recent orders valued from $9,000 to $70,000.
Clean Harbors operates predominantly as a net prime contractor with minimal subcontracting exposure; the award portfolio shows 99% prime contracts and only 1% subcontract activity. Across SCI-reportable prime contracts, the vendor delivered no sub-hours, indicating in-house execution. Named subcontracting relationships appear in recent work under Leidos (pre-design investigations and PFAS removal designs at Wright-Patterson Air Force Base), HII Mission Technologies Corp (aircraft frame transportation), and V2X Systems LLC (RHS Phase 2 connection work). SCI-reported invoiced revenue for the vendor totals $4.5 million in FY2025 across 8.0 FTEs on prime contracts—a partial and conservative view covering only service contracts above the $150,000 reporting threshold. The FTE trajectory shows growth from 0.5 FTEs in FY2022 to 17.9 FTEs in FY2025 on SCI-reportable work. Activity volume has fluctuated: 735 awards in 2022, climbing to 1,573 in 2024, then settling to 688 in 2026 year-to-date. Within the next twenty-four months, 719 awards with a combined potential value of $20.3 million face completion and recompete exposure. The vendor's dominant NAICS concentration is hazardous waste treatment and disposal (10,238 awards) and product service code Housekeeping-Waste Treatment/Storage (10,229 awards), reflecting the industrial-commodity nature of its federal work centered on post-use environmental remediation at military installations and federal facilities rather than advisory or engineering services.
