| Objectives | Santa Fe Aggregates, Inc. and Walter John Seaborn (hereinafter Discharger) is currently discharging pursuant to Order No. R5-2005-0058 and National Pollutant Discharge Elimination System (NPDES) Permit No. CA0082201. The Discharger submitted a Report of Waste Discharge, dated 16 December 2009, and applied for a NPDES permit renewal to discharge up to 1.99 million gallons per day (mgd) of groundwater and storm water from the Sand and Gravel Plant, hereinafter Facility.
For the purposes of this Order, references to the “discharger” or “permittee” in applicable federal and state laws, regulations, plans, or policy are held to be equivalent to references to the Discharger herein.
Santa Fe Aggregates, Inc. owns and operates a sand and gravel excavation and processing facility. Walter John Seaborn owns the land on which the Facility is located. The treatment system consists of a settling pond where groundwater and storm water are collected prior to discharge. Wastewater is discharged from Discharge Point 001 (see table on cover page) to the St. Johns River, a water of the United States and a distributary of the Kaweah River (at a point below Lake Kaweah) within Kaweah Delta Hydrologic Area (No. 558.10). A portion of the pumped groundwater is diverted to a groundwater recharge system west of the Facility (Discharge Point 002). The groundwater recharge system is a drainage basin that consists of underground perforated pipes within a layer of gravel. The perforated pipes allow water to drain into the surrounding gravel layer and percolate into the local groundwater aquifer. The Discharger also operates an aggregate processing facility. Wash water that is generated from processing is discharged to a second settling pond, Settling Pond No. 2 (Discharge Point 003), and recycled. Wash water is not discharged to the St. Johns River. |
