LochheaA <br />E.ecwive Dueaor <br />Michael B. Long <br />Division Dnecmr <br />We currently hold $16,559 in forfeited bond monies for this site. Here's what remains to be done <br />(see attached memos from Janet & Byron): <br />Water from Pond 4 may be seeping out below the pond's embankment and possibly <br />contributing to a small slump downhill. Byron has suggested that the base of the primary <br />riser be grouted, that the pond be lined with bentonite, that the exit low-flow discharge plastic <br />tube be replaced with a metal pipe, and [hat the new metal exit pipe be extended to the base of <br />the slope. <br />2. A hairpin turn in Pit 4's access road needs reinforcement or repair. <br />3. A ditch along the access road to Pit 2/3 needs riprap and repair. <br />4. Spring water flow across the access road to Pit 2/3 needs managing (water bars, etc.). <br />I've attached copies of some recent inspection reports for Grassy Gap. These provide some <br />additional detail that may be useful. <br />If you have any questions, see me or Janet. <br />Cc: Janet Binns <br />Byron Walker <br />graS S yg apmOM:\oss\~ rc\grusygapmo. doc <br />
