In addition, a small sump, called the Facilities Sump, located immediately north of the North Portal, has <br />been installed as an additional sediment trap leading to Sump 5. It is part of the drainage area to Sump 5 <br />and therefore, does not require a separate calculation for size. However, it will take some burden off <br />Sump 5 and the facilities Sump will be cleaned out of sediment, as needed. <br />It is proposed that this effort be done on the entire slope as shown on Map C -2, however, the lower <br />portion of the slope is on the McIntyre property and access was not allowed there for the work done in <br />2010. <br />Yule Quarry January 2013 33 <br />
