The Department of the Interior Fish and Wildlife Service seeks herbicide application treatment services for invasive species control at Santee National Wildlife Refuge in South Carolina, with proposals due August 18, 2026. The procurement is a Total Small Business set-aside, restricting competition to certified small businesses.

Place of performance is Clarendon, South Carolina. The scope covers treatment of 257 acres on Dingle Pond using aquatically approved imazamox herbicide at 2 quarts per acre, targeting cattail, cutgrass, water hyacinth, alligator weed, parrot's feather, and Chinese tallow tree to reduce invasive species by 95%. Work may be completed during August 1–September 30, 2026 or June 1–September 30, 2027, with possible weather-related extensions. The contractor must be fully licensed, bonded, and insured in South Carolina and is responsible for all equipment, herbicide, adjuvant, and water transportation.
