 at least one of six factors in order to justify not meeting the 

 minimtim '*fish2d}le/swimm2U3le'' designated uses or to remove such a 

 designated use. The analysis must show that attaining a use is 

 not feasible becatise of: naturally occurring pollutant 

 concentrations; natural flow conditions or water levels that 

 cannot be made up by effluent discharges without violating state 

 %raiter conservation requirements; htman caiised pollution that 

 cannot be remedied or that would cause more environmental deunage 

 if corrected; hydrologic modifications, if it is not feasible to 

 restore the «rater to its original conditions or operate the 

 modification to attain the tise; natural non-water quality 

 physical conditions precluding attainment of aquatic life 

 protection uses; or controls more stringent thsm those required 

 by §301 (b) and §306 would result in substantial and widespread 

 economic and social impact.
