Set Environmental Inc.

Set Environmental Inc., a for-profit Subchapter S corporation based in Wheeling, Illinois, operates as a prime contractor (99% of awards) providing hazardous waste disposal, regulated waste shipment, environmental remediation, and emergency spill response services to federal agencies under full and open competition with no SBA set-aside certifications. The company competes in NAICS 562112 (Hazardous Waste Treatment and Disposal) and related environmental remediation categories, with a primary service portfolio centered on routine hazardous materials handling, quarterly waste removal, 24/7 emergency response, and compliance with Resource Conservation and Recovery Act Subtitle C and other federal environmental regulations.

Set Environmental's customer base spans 28 distinct federal agencies, with concentration in three primary agencies accounting for 55% of recent awards by count. The Department of Justice Drug Enforcement Administration leads by combined potential value at $16 million across 97 awards, followed by the Department of Homeland Security U.S. Coast Guard at $12 million across 16 awards, and the Department of Agriculture Animal and Plant Health Inspection Service at $6.9 million across two awards. By award count, the Defense Logistics Agency accounts for 116 awards (though valued at only $25 thousand in combined potential value), followed by DEA at 97 awards, and the Department of Transportation Federal Aviation Administration's Franchise Acquisition Services at 54 awards valued at $3 million combined. This concentration pattern reflects Set Environmental's dual role: high-volume commodity disposal for DLA and high-value environmental response work for DOJ, Coast Guard, and USDA.

Set Environmental holds two active prime IDVs anchoring the recent award portfolio. The FAA single-award Indefinite Delivery Contract (6973GH-25-R-00129), awarded July 1, 2025, carries a ceiling of $1.278 million through July 15, 2030, for comprehensive hazardous waste disposal at the Mike Monroney Aeronautical Center in Oklahoma City, encompassing 23 line items for corrosive cleaning liquids, solvents, waste fuels, paint-related materials, universal waste batteries, and potentially infectious materials, plus quarterly waste removal and 24/7 emergency response within a 60-mile radius. The U.S. Coast Guard single-award Basic Ordering Agreement, awarded April 25, 2024, provides up to $3.99 million through April 24, 2027, for emergency oil spill and hazardous chemical incident mitigation in the Great Lakes region. Set Environmental also places task orders under the DEA's Blanket Purchase Agreement DJDEAHQ060009BPA (72 task orders) and the DLA Indefinite Delivery Contract SP440002D0003 (19 task orders). Recent representative prime work includes a $20 thousand purchase order from Federal Correctional Institution Bastrop for hazardous waste removal (awarded October 1, 2026), a $1.278 million FAA single-award IDC for MMAC hazardous waste disposal (awarded July 1, 2025), a $3.99 million Coast Guard BOA for Great Lakes emergency response (awarded April 25, 2024), and multiple recurring $5 thousand to $45 thousand delivery orders from the FAA for regulated waste shipment, PCB removal, battery shipment, and garnet slurry disposal under contract 6973GH-20-D-00049.

Activity has remained steady, averaging 9.6 awards per year over the past five years (2022–2026), with 558 total awards in the source data spanning from February 1991 to October 2026. Combined potential value is $44.4 million, with $19.1 million obligated (43% realization rate). Only one award faces recompete in the next twenty-four months, carrying $20 thousand in potential value, indicating minimal near-term recompete cliff exposure. Set Environmental subcontracts to Weston Solutions Inc. on environmental assessment and remediation support under a START V CERCLA task order program (three sub-awards in February, October, and November 2024 for sampling, investigation, and remediation services), though subcontracting comprises only 1% of the vendor's recent award footprint. The vendor's service delivery is concentrated geographically at Oklahoma City FAA facilities and distributed across emergency response locations in the Great Lakes region and inland U.S. locations, with recent spill response work at Morris, Minnesota and Windom, Minnesota. Set Environmental has maintained federal contracting relationships since at least August 2001 (SAM.gov registration date referenced in source summaries), demonstrating three decades of continuous federal environmental services delivery.
