OJVOC proposes that monthly averages be <br />tracked aril utilized to determine replacement water delivery rates aryl <br />that replacement water delivery rates be recalculated on an annual <br />basis. Initially, CL'fVOC prapoe~es the following replacement water <br />delivery rates used upon data collection efforts to date: <br />Month Replacement Volume (cr[an) <br />Jan 2 <br />Feb 2 <br />Mar 7 <br />Apr 11 <br />May 7 <br />Jun 5 <br />Jul 5 <br />Aug 4 <br />Sep 3 <br />Oct 3 <br />Nw 2 <br />Dec 2 <br />• <br />~VCC will only honor a call far replacement water if an anomalous or <br />sudden diminution or disruption of flow occ~u-s which can be reasonably <br />linked to mine activities. To the extent possible, other similar <br />resources or features in the area will be monitored concurrently with <br />Spring 31 and used for ~arative purposes. A water meter <br />installation will be established downstream on the pipeline at a point <br />below the Lower Cabin Spring. OOVCC will also monitor this point on <br />a monthly basis to record ir-stantanears and average flow rates. Zhe <br />Division will have final authority as to whether trucked water <br />deliveries arri further water replacement plan provisions should be <br />initiated. <br />Phase 3:) In the unlikely event that flan from the Upper Cabin Spring <br />is cctt~letely and suddenly disrupted or noticeably diminished as a <br />result of mining, or if water quality is adversely impacted, repair <br />procechrres as detailed in Volume 3, Sutsidence Repair Handbook, will <br />be implemented. <br />Phase 4:) In the event repair efforts are unsu~sful, steps will be <br />taken to extern the pipeline now serving the Orchard Valley West Mine <br />south to a point at which water from the Steven's c~ilch water well <br />known as Orchard Valley Well No. 3 can be introduced into the Stucker <br />Mesa Domestic Water Company's pipeline as a permanent replacement <br />sur~lv._ 'Eae orr-t,a.-rt_ VaLlav, Well No. 3 can provide water o£ r ~ hlP <br />• quality and senior priority to the Stucker Mesa system.
