Administrative Draft Environmental Impact Report <br /> Gill Medical Center Project <br /> could degrade surface water and/or groundwater and violate water quality standards within the Basin <br /> Plan. <br /> However, the Project would include an onsite sanitary sewer and wastewater treatment system. <br /> Wastewater generated by the Project would be conveyed to an advanced "package plant"wastewater <br /> treatment system that would be specially designed to treat and remove hospital generated liquid medical <br /> waste.The resultant water quality would be treated to a level suitable for National Pollutant Discharge <br /> Elimination System (NPDES) permitting by the Regional Water Quality Control Board with Waste <br /> Discharge Requirements (WDRs). RWQCB Basin Plan limits and drinking water maximum contaminant <br /> levels (MCLS) for a range of parameters is provided in Table 4.12-3.The values in this table provide an <br /> indication of the level to which the wastewater would need to be treated for many substances to obtain <br /> and comply with an NPDES permit and WDRs. Treatment to these levels would also produce "recycled <br /> water" suitable for use in outdoor reflecting ponds, as landscape irrigation, or for agricultural production. <br /> Table 4.12-3.RWQCB Basin Plan Limits for NPDES WDR Discharges <br /> Standards <br /> Tier 3 Constituent Units Basin Plan <br /> Limit Title 22 MCLs <br /> Aluminum pg/L NA 1,000 <br /> Ammonia,as N pg/L NA 25 <br /> Fecal Coliform mpn/mL 100/100 <br /> Iron pg/L 300 300 <br /> Manganese pg/L 50 50 <br /> Nitrate as NO3 mg/L NA 45 <br /> Nitrite as N mg/L NA 1 <br /> Nitrate+Nitrite,as N mg/L 10 10 <br /> pH std units 6.5-8.5 6.5-8.5 <br /> Specific Conductance(EC) pmhos/cm 340 900 <br /> Chloride mg/L NA 250 <br /> Sulfate mg/L NA 250 <br /> Fluoride Mg/L NA 2 <br /> Hydrology and Water Quality 4.12-21 October 2021 <br />
