Conditions appeared stable <br />and acceptable at ponds 005 and 009. The trench has been <br />excavated and the riprap for the french drain should start <br />arriving next week to complete the repairs at the slump area in <br />the NE corner of pond 006. Work has been completed on the 006 <br />Pre-Settling Basin and the related inlet and outlet channels. <br />The pond 006 emergency spillway has been revised and we will <br />raise the primary spillway once the water level has dropped low <br />enough at the pond. <br />If you have any questions, please call me. <br />Sincerel <br />Michae <br />Engine <br />Enclosure(s) <br />c: Dennis Jones (SCC) <br />Gary Wendt (PWCC) <br />ltavil~~ P.E. <br />Managlt~ <br />JUL 171~gg <br />Seneca Coel Company • P.O.
