As part of TR-97, a small portion(0.1 acres)of the slope angle will change from 2H:1 V to 1.5H:1 V.
Please see the stability analyses for this section incorporated into Volume IX.
"* The Gob Pile Sediment Pond is also known as`Pond D. As part of TR-43. Pond D was redesigned, and
the supporting documentation for the new design is no longer part of this Volume. The PHC for Pond D is
located in Volume III,pages Exh. 8-17 through 19, the SEDCAD output is now located in Volume 111,pages
207&208. The upland runoff areas are shown on Map 20 in Volume H. Culverts and ditches have also
been redesigned and the design information is included in Exhibit 8 of Volume W.
