The Saticoy Sanitary District Treatment Plant has a capacity of 2.2 milliongallons per day and is undergoing expansion and upgrading to tertiary treatment. Of thewastewater sent to the Ventura WRF, a minimum of 5.6 MGD of the effluent is discharged tothe Santa Clara Estuary as required by the existing Regional Water Quality Board (RWQCB)Permit. The remaining effluent is either transferred to recycling ponds, where a portion isdelivered as reclaimed water, or lost through percolation or evaporation. Methods fortreatment of residual solids include thickening, anaerobic digestion, and dewatering by filterpresses prior to land application.d. Wastewater Conveyance Infrastructure. Wastewater conveyance infrastructureserving the Project Area is owned and operated by the City, the County, and Saticoy SanitaryDistrict. The wastewater conveyance infrastructure consists of gravity collection mains and onewastewater lift station. The City collection system includes seven major tributary, or planning,areas (see Figure 4.14-1) with a total service area of 31,309 acres. The Project Area is serviced bythe Wells Road Valley Trunk Sewer.e. Solid Waste. Solid waste generated in the Project Area would likely be taken toeither the Toland Road Landfill or the Simi Valley Landfill. The Toland Road Landfill has amaximum permitted capacity of 1,500 tons/day and receives on average 1,300 tons/day (Sally4.14-9City of Ventura
Saticoy & Wells Community Plan and Code EIRSection 4.14 Utilities and Service SystemsColeman, 2008) while the Simi Valley Landfill has a maximum permitted capacity of 3,000 tonsper day. There are 200 tons available capacity at the Toland Road Landfill.4.14.2 Impact Analysisa. Methodology and Significance Thresholds. Development facilitated by the Projectwould result in potentially significant impacts if growth accommodated by the Project wouldresult in substantial adverse physical impacts associated with provision of new or physicallyaltered governmental facilities, or the need for new or physically altered governmental facilities,the construction of which could cause significant environmental impacts, in order to maintainacceptable service ratios or other performance objectives.Water. Water demand was estimated using factors from the City of Ventura’s UrbanWater Management Plan. Impacts related to the implementation of the Project would beconsidered substantial if development facilitated by the Project would:• Substantially deplete groundwater supplies or interfere substantially withgroundwater recharge such that there would be a net deficit in aquifer volume or alowering of the local groundwater table level (e.g., the production rate of pre-existingnearby wells would drop to a level which would not support existing land uses orplanned uses for which permits have been granted);• Require or result in the construction of new water facilities or expansion of existingfacilities, the construction of which could cause significant environmental effects; or• Fail to have sufficient water supplies available to serve the project from existingentitlements and resources, or are new or expanded entitlements needed.Wastewater. Wastewater generation was estimated using factors from the VenturaStandards and Design Manual. Table 4.14-5 lists wastewater generation factors applied to newdevelopment in Ventura.Impacts related to the Project would be considered substantial if growth accommodated underthe Project would:• Require or result in the construction of new wastewater treatment facilities orexpansion of existing facilities, the construction of which could cause significantenvironmental effects; or• Result in a determination that the wastewater treatment provider that it does nothave adequate capacity to serve projected demand in addition to existingcommitments.Solid Waste. Solid waste generation was estimated using factors from the 2005 GeneralPlan FEIR. Impacts are considered significant if solid waste generated by growth that could beaccommodated under the Project would exceed the existing or planned capacity of landfills ordo not comply with federal, state, and local statutes and regulations related to solid waste.4.14-10City of Ventura
