A sequenced approach to monitoring system development is necessary when 1and~ill development progresses Tn a dawngrad~ent ~ash~an and the pra~ected l~~e/capacity o~ the proposed development is extended. zt is suggested that the wells propas~d for the southern property boundary be moved northward to a posi ti on which coincides wi ~h the ten--year waste ~~ 11 1 ~ mi t . These we I 1 s would subsequently be replaced w~ th . we11s located at the south property boundary when the ~~11 progresses to this point. zt should be noted that ~ •~ the waste recei v~ ng rates decrease, the we11 s waul d be •i n position to moni tar the ~aci 1 ~ ty an an expanded time game conclusion : overal 1, ,the report does a very good ~ ab o-~ characteri ~~ ng the complex geology o~ the expansion site. z think one,o~ the next steps wil~ be tv sit down w~ th WM~ to d~ scuss the approach to the mono tors ng network. wMS ~ s prapos~ ng we11 installation this summer, so this Should happen soon.
