About this opportunity
The Department of the Army Corps of Engineers Nashville District awarded a sole-source contract to Lewis Environmental Consulting, LLC on June 1, 2026 for mussel relocation services under a limited sources justification.
The justification cites RFO 12.102(a), only one source available. The rationale centers on urgency and contractor-specific knowledge. The Federal Navigation Channel at Tennessee River Mile 155 (Beech Creek area, Cliffton, Tennessee) has narrowed from approximately 1,000 feet to 280 feet due to shoaling, creating navigational hazards that threaten commercial shipping. Environmental regulations restrict mussel relocation to a June 1 through August 31 window, creating time pressure incompatible with full and open competition. Lewis Environmental Consulting conducted the original mussel survey and possesses critical knowledge of mussel locations within the designated dredge area; soliciting competition would require independent surveys by other contractors, duplicating costs and causing unacceptable delays. A Notice of Intent posted to SAM.gov for five calendar days on April 6, 2026 drew only one contractor response. The contract is a fixed-price purchase order with a 10-calendar-day performance period, procured using FY 26 Civil Works funds. Work involves relocating endangered mussels from the Federal Navigation Channel and placing them in a designated area outside the authorized channel behind Beech Creek Island. Contracting Officer Alison Abernathy approved the award on April 21, 2026 after legal review by Assistant District Counsel Kathleen Miller confirmed adequacy of the justification and fair and reasonable pricing.
