INFORMATION SHEET • • 3 <br /> WASTE DISCHARGE REQUIRMENTS ORDER NO. R5-2002-0213 <br /> U.S. DEPARTMENT OF DEFENSE <br /> DEFENSE LOGISTICS AGENCY <br /> DEFENSE DISTRIBUTION DEPOT SAN JOAQUIN <br /> SHARPE GROUNDWATER REMEDIATION SYSTEM <br /> SAN JOAQUIN COUNTY <br /> groundwater from the DDJC-Sharpe facility, there are periods of limited or no flow in the SSJID <br /> Canal. <br /> Previous Order No. 95-258 considered French Camp Slough the receiving water for this discharge. <br /> This Order considers the impact of the discharge on the existing beneficial uses of both the SSJID <br /> Canal and French Camp Slough. All of these identified waters are considered waters of the United <br /> States. <br /> Beneficial Uses <br /> The Basin Plan at page II-2.00 states that: "Existing and potential beneficial uses that currently <br /> apply to surface waters of the basins are presented in Figure II-1 and Table II-1. The beneficial <br /> uses of any specifically identified water body generally apply to its tributary streams." The Basin <br /> Plan does not specifically identify beneficial uses for the SSJID Canal or French Camp Slough,but <br /> the Basin Plan does identify present and potential uses for the San Joaquin River and the <br /> Sacramento-San Joaquin Delta(Delta), to which they are tributary. A portion of French Camp <br /> Slough downstream of the confluence with the SSJID Canal is located within the designated <br /> boundary of the Delta. French Camp Slough upstream and in the immediate vicinity of the <br /> confluence with the SSJID Canal is not located within the designated boundary of the Delta. <br /> In Table II-1 the Basin Plan identifies the following existing beneficial uses of the San Joaquin <br /> River and the Delta downstream of the discharge: municipal and domestic supply, agricultural <br /> irrigation, agricultural stock watering, industrial process water supply,industrial service supply, <br /> body contact water recreation, other non-body contact water recreation,warm freshwater aquatic <br /> habitat, cold freshwater aquatic habitat, warm fish migration habitat, cold fish migration habitat, <br /> warm spawning habitat, wildlife habitat, and navigation. <br /> The Basin Plan on page 11-1.00 states: "Protection and enhancement of existing and potential <br /> beneficial uses are primary goals of water quality planning..." and with respect to disposal of <br /> wastewaters states that"... disposal of wastewaters is [not] a prohibited use of waters of the State; <br /> it is merely a use which cannot be satisfied to the detriment of beneficial uses." <br /> SSJID Canal <br /> While flow in the SSJID Canal is tributary to French Camp Slough and the Delta,the Canal itself <br /> is a constructed agricultural drain. As a constructed agricultural drain,the SSJID Canal is not <br /> subject to the tributary provisions of the Basin Plan. The SSJID Canal is not a"stream" as used in <br /> the Basin Plan"tributary" language and, therefore,the Regional Board will not apply the <br /> beneficial uses of the downstream water bodies to SSJID. The beneficial uses of the SSJID Canal <br /> are therefore identified by other statutory designations and/or the actual existing beneficial uses of <br /> the receiving water. USEPA's water quality standards regulations require protection of all existing <br /> uses. Existing uses are those uses actually attained in the water body on or after 28 November <br /> 1975,whether or not they are included in the water quality standards. In reviewing what existing <br />
