f <br />y~ V <br />Operator claims that due to the nature of their refuse (high content of mudstone I believe) it is not feasible for them to <br />maintain terrace drains, as equipment would get buried in muck. They further claim that, because they need large <br />expanses of acreage to spread and dry their refuse, a construction process employing successive benches with terrace <br />drains is not feasible. Does the construction and final configuration of the piles at Deserado appear to conflict with 4.09.2 <br />(5)? Operator states that because the drainage off the piles is dispersed rather than concentrated, the drainage is not <br />"directed" over the outslope. Comments?Suggestions? <br />In the attached photo from May, 2002, RPM ~Sfn the foreground; view is to the east, with RP-2/3/4 immediately to the east <br />of RP-5, and RP-1 across the road to the There is a temporary pile on top of the RP-5 graded surtace. The <br />temporary pile accumulates during the winter, because operator is unable to get sufficient drying to obtain satisfactory <br />compaction during winter months, and must stockpile refuse for final spreading in summer and fall. <br />Please don't spend a lot of time on this, but if possible I would like your input on the questions I have posed, based on your <br />experience and knowledge of refuse pile drainage and construction approaches as related to the cited regulations. <br />Deserado's combative environmental coordinator, along with ttje engineer who designed and certifies the piles and their <br />chief engineer are coming in to the office next week to discuss these issues. <br />Thanks alot. <br />Dsc_0133 530-02 <br />venal jp0 <br />
