Farrell : <br /> In answer to your February 2C , 1980 letter requrstinci <br /> clarification and suggestions concerning the waste Ciisposal t1.n <br /> submitted to the Division ,, the following is submitted . <br /> (1 ) The "rocky over5or&en" proposed for the tot three feet Cf <br /> fill is the material excavated from the zone between the <br /> topsoil layer and Wroc_% . This material is P rocky roil . <br /> The soil portion of the "rocky overburden" was classified as <br /> ,and and gravel , clayey. See attacheO plan map of loccatdon <br /> of stockpiled ovt rburden (CDs 11 and OBS #2 ) . 7h:e <br /> stockpiles, topsoil (TS1 1 and `i'Si 2) has not been coIImitteC to <br /> any reclam:ati or: Efforts . Amendment #_' requires SunnysiVe <br /> Cole, to submit a plan for its usage to the =D and REM for <br /> approval prior to usage . We ,;ill incorporate it into final <br /> reclomation efforts for SunI"Sysiue Basin and will discuss <br /> possible affective a o s of the to"soil during your next Site <br /> visit . <br /> (2) The Lake Emma test plots do not contain overburden material . <br /> it shou1Ci be possible to expaK the test to include <br /> overburden material this summer in order to determine the <br /> feasibility of revegetatino the L ke Emma fill . If the <br /> overhurCen material is ametlable to revegetation , the top two <br /> feet of fill material could be left oncompacted an(' <br /> vegetated as the preferred iaethoC of reclamation. <br />
