The primary bases for the conclusion of dewatering effects approxinately a mile from the plant is the absence.of an aquifer confining layer in the vicinity of the location in question. The USGS, and to my knowledge no noe else, has dada to support such a conclusion. The USGS and.1ational Park Service plan to attempt to verify the assumption in the future (possibly by FY 81).
I recernend that the Pemitteels proposed changes to the monitoring and mitigation program be disapproved. Eurthemore, I reco:nend that I&E monitor construction dewatering activities to assure that the Pemittee adequately meets his CP requirenents, and has not violated reporting require-ments. Finally, as a matter of clarification, I was informed by the Pemittee's representative at the January 31 meeting that anomalies in the Novenber 1979 data supplied to us in support of the Construction Pemit were caused by testing of the mitigation program and by a landslide in the southwest corner of the excavation.
