Mr. Heok indicated that he <br />collected about six inches of precipitation in his rain gauge for that storm event, Thus, it can <br />be assumed the August storm created severe Hood eondidons at the quarry site. Once runoff <br />waters flowed over the spillway, significant amounts of suspended pertfcles must also have <br />discharged from the 16.5 acres of bare around onto downstream properties, <br />Summary <br />1. The hydrologic twaluation submitted to the DMG is not correct nor complete. <br />2, The; slsing and design of a eedimeat containment system are not correct nor adequate. <br />3. SuBloierst infotrnadon has sot been provided to meet S WMP criteria. <br />4. The quarry appears to be a moot source of sediment onto downstream properties. <br />Please call if you have any <br />Yours truly, <br />HydroDynnmic~~o~ <br />`'Jerald S.
