* The Gob Pile Sediment Pond is also known as `Pond D. As part of TR -43, Pond D was
redesianed. and the suwortinq documentation for the new design is no longer part of this
Volume. The PHC for Pond D is located in Volume lll, pages Exh. 8 -17 through 19, the
SEDCAD output is now located in Volume lll, pages 207 & 208. The upland runoff areas are
shown on Map 20 in Volume 11. Culverts and ditches have also been redesigned and the design
information is included in Exhibit 8 of Volume ill.
