This would also apply to areas where clay is mined. b. Rectanwtlon Ptan Seed miX revision - The following mix will replace the approved mix. This mix is based on recommendations made by U.S.F.W.S. for use on the site. To supplement this planting we will now add a mulch cover of 2 tons of certified weed free native hay or straw per acre, crimped in.

Research of groundwater wells show the water elevation on the site averages 50 feet below the surface. This suggests that the water table slopes west to east across the site. The site its self has a 40 foot elevation in the same direction. Knowing that water eleva-
