Stephen Ngotho

Stephen Ngotho supports the Defense Logistics Agency Disposition Services – Ebs (SP4500) in managing procurement activities critical to the safe, compliant, and environmentally responsible disposition of Department of Defense hazardous and nonhazardous waste streams. He plays a pivotal role in acquiring specialized treatment, transportation, and disposal services that ensure regulatory adherence across DoD installations and overseas operations. His acquisitions primarily focus on hazardous waste management contracts, requiring deep technical understanding of EPA and DOT regulations, treatment technologies, and chain-of-custody protocols. Ngotho ensures all procurements align with federal environmental stewardship mandates and support global military readiness through reliable, auditable waste resolution solutions. He maintains established working relationships with key contractors including Boh Environmental, L.L.C., TRI-STATE GOVERNMENT SERVICES INC, INDUSTRIAL WASTE UTILIZATION, INC, STREET LEGAL INDUSTRIES, INC, and TRADEBE ENVIRONMENTAL SERVICES, LLC. These vendors are selected for their proven capabilities in handling complex waste streams, permitting compliance, and regional service coverage. Ngotho’s contracting approach emphasizes performance-based outcomes, technical validation, and long-term vendor reliability, fostering strategic partnerships with firms that demonstrate operational excellence and environmental accountability. His procurement patterns reflect a strong preference for open competition, with 83.3% of awards issued without set-asides, indicating a focus on capability-driven selection over socioeconomic categorization. However, he consistently allocates 16.7% of opportunities to Total Small Business Set-Asides under FAR 19.5, demonstrating a measured commitment to small business participation without compromising mission-critical performance standards. Ngotho’s portfolio is exclusively focused on NAICS 562211—Hazardous Waste Treatment and Disposal—reflecting deep specialization in managing regulated waste streams such as solvents, heavy metals, PCBs, and contaminated soils. He procures services including incineration, chemical treatment, secure landfill disposal, and recycling technologies, requiring contractors to maintain RCRA permits, hazardous material transport licenses, and environmental monitoring capabilities. His expertise lies in evaluating technical proposals, compliance documentation, and site-specific operational readiness to ensure mission continuity and environmental integrity.
