Clean Harbors Environmental Services Inc.

Clean Harbors Environmental Services Inc., doing business as Clean Harbors Of Connecticut Inc., is a large for-profit environmental services company headquartered in Norwell, Massachusetts, that operates as a prime contractor delivering hazardous and non-hazardous waste management, environmental remediation, emergency response, and industrial cleaning services to federal agencies. The subsidiary of parent Clean Harbors Environmental Services Incorporated competes predominantly in full-and-open procurements and holds no SBA set-aside designations.

Clean Harbors' federal footprint centers on hazardous waste treatment and disposal, with 99% of recent awards as prime contracts (11,878 of 11,972 total awards). The vendor's core capability portfolio spans hazardous waste removal, transportation, treatment, storage, and disposal; chemical waste management; PFAS liquid handling; laboratory pack services; oil spill and emergency spill response; waste characterization and analytical testing; lead acid battery and lamp disposal; reactive-ignitable toxic liquid handling; and specialized industrial cleaning at military installations and federal facilities. Representative work includes a $832,000 BPA call from the Bureau of Engraving and Printing for industrial hazardous and non-hazardous waste disposal services at Fort Worth, Texas (awarded June 1, 2026); a $455,039.13 BPA call from the same agency for Ordering Period 4 hazardous and non-hazardous waste removal services in Washington, DC (awarded June 15, 2026); a $334,055.23 BPA call from the Environmental Protection Agency for chemical and hazardous waste disposal services in Cincinnati, Ohio under time-and-materials pricing (awarded July 7, 2026); and a $142,500 delivery order from the Pacific West Area for collection, removal, and disposal of hazardous wastes in Wenatchee, Washington, with ultimate completion through March 2031 (awarded March 24, 2026).

Clean Harbors holds active labor categories on the GSA Multiple Award Schedule spanning foreman through emergency-response supervisor roles, with hourly rates ranging from $89.51 to $159.61 and education requirements of high school through bachelor's degree; no security-cleared labor is offered. The vendor's GSA Schedule position anchors delivery orders across civilian agencies including the Environmental Protection Agency, Department of Agriculture, Department of Veterans Affairs, and Department of the Interior.

Customer concentration is heavily weighted to Defense Logistics Agency Disposition Services, which represents 9,467 of 11,972 awards (79% of award count) and $407.5 million of the combined $1.15 billion potential value (35% of dollars). The top five customer agencies by count account for 87% of awards. The secondary tier includes the Department of the Treasury Bureau of Engraving and Printing (73 awards, $51.8 million), the U.S. Coast Guard (373 awards, $46.8 million), the Department of Agriculture Animal and Plant Health Inspection Service (75 awards, $38.4 million), and the Department of the Navy Naval Sea Systems Command (224 awards, $21.2 million). The divergence between award count and potential value reflects the Defense Logistics Agency's high-frequency, smaller-dollar delivery orders alongside larger single awards from Treasury and USDA.

Clean Harbors' vehicle position rests primarily on five Defense Logistics Agency Disposition Services indefinite delivery contracts: SP450022D0009 (1,752 task orders, $15.1 million), SP450020D0015 (1,101 task orders, $12.1 million), SP450017D0008 (958 task orders, $7.3 million), SP450022D0011 (908 task orders, $8.9 million), and SP450008D0019 (742 task orders, $10 million). The vendor also holds a single-award $500,000 Blanket Purchase Agreement with the U.S. Department of Agriculture's Food Safety and Inspection Service through August 2030 and a $900,000 multiple-award BPA with the Bureau of Reclamation under the GSA Multiple Award Schedule through July 2030, both established in 2025. In July 2026, the Environmental Protection Agency established a single-award $815,187.00 BPA for chemical and hazardous waste disposal services under the GSA MAS, running through July 2031. The vendor also holds a single-award indefinite-delivery contract with Veterans Integrated Service Network 12 (ceiling $548,884.02, through April 2031) for hazardous waste collection at the Clement J. Zablocki VA Medical Center in Milwaukee.

Activity has been volatile. Awards per year averaged 1,352 from 2022 through 2025 but dropped to 377 in 2026 year-to-date. Within the next twenty-four months, 667 awards (combined potential value $16.5 million) reach ultimate completion date, creating a discrete recompete window. The vendor's category concentration is extreme: hazardous waste treatment and disposal NAICS accounts for 9,942 awards, and PSC Housekeeping-Waste Treatment/Storage carries 9,931 awards, indicating minimal diversification.

Clean Harbors operates as a net prime across the federal footprint (99% prime split), with minimal subcontracting exposure. Service Contract Inventory reporting captures 39 records (34 as prime, 5 as named subcontractor) spanning FY2022–FY2024, showing no invoiced revenue reported and only 3.8 FTEs recorded in FY2024 across SCI-reportable federal service contracts above the $150,000 threshold. The vendor's federal services work is thus substantially below the SCI reporting floor or concentrated in goods, micro-purchases, classified work, or cost-plus-fixed-fee arrangements outside SCI scope.

The vendor subcontracts to larger primes including Leidos Inc. (pre-design investigations and PFAS removal designs at Wright-Patterson Air Force Base, awarded May 22, 2026), Vectrus Systems LLC (RHS Phase 2 work, April 17, 2026), Environmental Quality Management Inc. (Baldy Mesa sanitizer site removal labor and transportation, April 3, 2026), and Fluor Marine Propulsion LLC (Naval Nuclear Laboratory support work at Knolls Center Road, March 23, 2026).
