WASTE DISCHARGE REQUIRE._ _NTS ORDER NO. 3 <br /> LINNE ESTATES,LLC <br /> LINNE ESTATES WASTEWATER TREATMENT SYSTEM <br /> SAN JOAQUIN COUNTY <br /> 18. Both good practice and Section 3.3.2.b of the San Joaquin County Public Health Services <br /> Environmental Health Division Sewage Standards requires that 100-percent of open land equal to <br /> the size of the installed sewage system be available for future use if needed. The Discharger <br /> complies with this requirement. The replacement area is identified on Attachment C, which is <br /> attached hereto and made part of this Order by reference. <br /> 19. Untreated wastewater quality was estimated from published sources and is presented below: <br /> Constituent Units Concentration <br /> Biochemical Oxygen Demand mg/L 240 <br /> Total Suspended Solids mg/L 218 <br /> Total Nitrogen mg/L 34 <br /> 20. The RWD presents anticipated treated wastewater quality. The projected effluent quality <br /> constituents are presented below: <br /> Constituent Units Concentration <br /> Biochemical Oxygen Demand mg/L 15 <br /> Total Suspended Solids mg/L 15 <br /> Total Nitrogen mg/L 12 <br /> Total Coliform Organisms mpn/100 ml 23 <br /> Total Dissolved Solids mg/L 810 <br /> pH Std. Units 7 - 8 <br /> Collection System <br /> 21. A collection system "overflow" is a discharge to ground surface or to surface water from the <br /> collection system, wastewater treatment system, or disposal area. Temporary storage or collection <br /> facilities may be utilized during maintenance operations and discharges to these facilities are not <br /> considered overflow events, provided that the waste is fully contained and properly disposed of. <br /> 22. Potential causes of overflows within this system include grease blockages, root blockages, debris <br /> blockages, sewer line flood damage, vandalism, storm or groundwater inflow/infiltration, lack of <br /> capacity,power failures, and contractor caused blockages. <br /> 23. Sanitary sewer overflows often contain high levels of suspended solids, pathogenic organisms, <br /> nutrients, oxygen demanding organic compounds, oil and grease, and other wastes. Sanitary sewer <br /> overflows can cause temporary excedences of applicable water quality objectives, pose a threat to <br /> public health, adversely affect aquatic life, and impair the public recreational use and aesthetic <br /> enjoyment of surface waters in the area. <br /> 24. The Discharger is expected to take all necessary steps to adequately maintain and operate, and <br /> thereby prevent overflows from its collection system. A reasonable means to accomplish this is to <br /> update and implement a collection system operation and maintenance manual that includes <br /> overflow prevention and response features. <br /> W9.StaWbriwTl San loaquin\Linnc Estatm\Unnc WDR rLdoc <br />
