(“SPC”). The SPC proposes to build a multi-purpose yacht club and marina on Bluff Head Avenue in Little Compton, Rhode Island. The Permit regulates discharge from a reverse osmosis treatment system designed to desalinize well water and thereby provide potable freshwater to service the needs of SPC. The source of the brackish water to be desalinized is from three deep bedrock wells on the property. The Permit will allow the discharge of concentrated brackish groundwater from the reverse osmosis treatment system that consists of pre-filtration, reverse osmosis and ultraviolet disinfection.
