reasonable until a better determination can be made of how much topsand is • available for the final reclamation areas. A manure mulch will be applied at 30 tons/acre. After manure spreading, the approved seed mix will be drilled through the m anure mulch. Seeding will be from~April 1 to May 1. The seed mixture that is being used is: Rate in Lbs.

Species diversity success determination has been resolved as follows: CEC will establish a minimum of seven perennial species of which four are warm season grasses, two are cool season grasses and one is a forb to be measured by relative cover. No one component of the above should comprise greater than 40% relative importance nor less than 3% relative importance. CEC will continue to monitor revegetation in August. The established Osgood reference site and all plantings that have experienced three growing seasons will be monitored until such time as success standards for cover, production, and diversity have been attained. These areas will also be monitored in years nine and ten before final bond release. CEC estimates the number of samplings that will meet adequacy requirements for a given years monitoring, then divides the area into a 100' grid pattern, assigns consecutive numbers to each grid line intersection and takes a list of random numbers to determine which quadrant sites will be monitored. At least 10 samples from the reference area and 15 samples for post-mine sample areas will be taken. • 115 5/96
