Lewis Environmental Consulting, LLC

Lewis Environmental Consulting, LLC is a for-profit limited liability company based in Grand Rivers and Farmington, Kentucky that has been registered to receive federal awards since June 2008. The firm specializes in freshwater mussel and dive surveys, providing environmental assessment and monitoring services to federal agencies, particularly the U.S. Army Corps of Engineers. Lewis Environmental Consulting has established itself as a trusted partner for the federal government's water resource management, navigation infrastructure maintenance, and environmental stewardship missions, with particular expertise along the Ohio River and its tributaries across multiple states including Kentucky, Tennessee, West Virginia, Indiana, and Pennsylvania.

Lewis Environmental Consulting has delivered extensive contract work through delivery orders and purchase orders awarded by the U.S. Army Corps of Engineers across multiple districts, including ENDIST Louisville, ENDIST Pittsburgh, and the Huntington District. The company's services encompass comprehensive mussel population surveys, pre-dredging biological assessments, dive surveys, and related biological reporting conducted at various locations including lock and dam facilities, river reaches, and shoreline stabilization project sites. Specific project work has included mussel surveys at the Ohio River in Huntington, West Virginia; the Little Miami River in Loveland, Ohio; Allegheny River Pool Six near Freeport, Pennsylvania; Chickamauga Lock in Red Bank, Tennessee; Kanawha River upstream of Winfield, West Virginia; and numerous additional sites throughout the Ohio River basin. Individual delivery order and purchase order values have ranged from $2,800 to $176,665.50, with contract types classified as firm fixed-price arrangements. All delivery orders and purchase orders identified were awarded without additional small business set-aside designations at the task order level, though many were issued under small business set-aside parent vehicles. The company has demonstrated consistent capability to compete successfully in open market procurements despite its small business status.
