SHM Charleston City Marina, LLC

SHM Charleston City Marina, LLC, a Charleston, South Carolina–based marina operator, receives federal grant sub-awards exclusively as a recipient of pass-through funding from the South Carolina Department of Natural Resources under the Clean Vessel Act–Coastal program, with no prime contracting or IDV participation.

The vendor's federal footprint is narrow and specialized. All four awards in the source data are grant sub-awards flowing from the U.S. Department of the Interior Fish and Wildlife Service Region 4 through the South Carolina Department of Natural Resources, the prime grantee. The awards fund pump-out facilities and vessel waste management services at the Charleston City Marina. Combined federal obligation across all awards is $271 thousand. Recent sub-awards include a July 2025 Clean Vessel Act–Coastal award, a January 2024 award under the same program, and a July 2023 award for additional FY24 Quarter 4 pump-out funding. Activity is infrequent and episodic — one award annually or less across the 2018–2025 window — with the most recent award dated July 2025.

The vendor operates exclusively as a grant sub-recipient with a single federal customer agency (the Department of the Interior Fish and Wildlife Service Region 4 via the South Carolina Department of Natural Resources). No federal contract vehicles, prime contractor relationships, or independent federal contract authority appear in the source. SHM Charleston City Marina functions as a facility operator delivering environmental compliance infrastructure (pump-out and waste reception services) under state-administered federal grant programs, not as a federal contractor or equipment vendor. The vendor has no teaming or subcontracting relationships with federal primes.
