<br />" <br /> <br />,.... <br />o <br />(1;;. <br />o <br /> <br />Intercepted Groundwater* Policy <br />for Implementation of the Colorado River Salinity Standards <br />. Through the NPDES Permit Program <br /> <br />" <br /> <br />Adopted By <br />The Colorado River Basin Salinity Control Forum <br />October 20, 1982 <br /> <br />The States of the Colorado River Basin in 1977 agreed to the <br /> <br />"Policy fo:!:- Implementation of Colorado River Salinity Standards <br /> <br />through the NPDES Permit Program" with the objective for <br /> <br />industrial discharge being "no-salt return" whenev.er practicable, <br /> <br />That policy required the submittal ofinfo~~ation by the <br /> <br />applicant on alternatives, water rights, quantity, quality and <br /> <br />costs to eliminate or minimize the salt discharge. The <br /> <br />information is for use by the NPDES permit issuing agency in <br /> <br />evaluating the practicability of achieving no-salt discharge, <br /> <br />There are mines and wells in the Basin which. discharge <br /> <br />intercepte4 groundwaters. The factors involved in those <br /> <br />situations differ somewhat from those encountered in other <br /> <br />industrial 'discharges, continued development will undoubtedly <br /> <br />result in additional instances in which permit conditions must <br /> <br />deal with intercepted groundwater, <br /> <br />The discharge of intercepted groundwater needs to be <br /> <br />evaluated fn a manner consistent with the overall objective of <br /> <br />"no-salt return" whenever practicable. The following provides <br /> <br />more detail,ed guidance for those situations where groundwaters <br /> <br />are intercepted with resultant changes in groundwater flow <br /> <br />regime, <br /> <br />I. The "no-salt" discharge requirement may be waived at <br />the option of the permitting authority in those cases <br />where the discharge salt load reaching the main stem <br />of the Colorado Riv.er is less than one ton per day or <br />350 tons per year, whichever is less, Evaluation <br />will b~ made on a case-by-case basis, <br /> <br /> <br /> <br />* The term intercepted groundwater means all groundwater <br />encountered'during mining or other industrial operations, <br /> <br />~ <br /> <br />,1:, ~; <br /> <br />~>_i.cJL '^"_""''''''' <br /> <br />:i,h- <br /> <br />
