There are three operators at the Facility: GPRM Prestress LLC, Grace Pacific LLC, and GP Maintenance Solutions which is an operating unit of GP Roadways Solutions, Inc. (1) The GPRM Prestress operation occupies 18.9 acres of land within the property and its primary functions are manufacturing and distributing of precast and pre-stressed concrete products. (2) The Grace Pacific LLC operation occupies 5.5 acres of land within the property and its primary functions are a vehicle and equipment maintenance and repair facility, and a transportation baseyard for trucks and intermodal containers. (3) The GP Maintenance Solutions operation occupies 0.4 acres of land within the property and its primary functions are spray application of industrial coatings, warehousing or storage of protective coating products, and operation of a portable asphalt emulsion plant.

GPRM Prestress LLC requests to discharge industrial storm water runoff from the facility. Best Management Practices (BMPs) for storm water runoff and non-storm water sources will be implemented to minimize the discharge of erosion and other pollutants from entering receiving State waters. GPRM Prestress LLC has indicated that structural controls to reduce pollutants in the storm water runoff include concrete washout pit lined with an impermeable material, berms, storm water retention basin and a portable wash rack system for vehicle and equipment washing.
