<br />- 12 - <br />3.~? The application proposes establishment of approximately 60 woody stems <br />`~ per acre from mature transplant clumps and the planting of <br />approximately 100 woody seedling stems per acre. Thus, in order to <br />meet the woody stem density standard of 1000/acre, a major portion <br />(around 900 stems/acre) of the woody plants would have to establish <br />from natural or artificial seeding or vegetative propagules. Does <br />monitoring data collected at the Eckman Park Mine indicate that such <br />results would be expected? Woody plant density data collected <br />previously by CYCC at the Eckman Park Mine should be submitted for <br />t inclusion in the application, <br />G4 \\ A revegetation monitoring plan should be included in the application. <br />At a minimum, the plan should include provisions for collecting <br />representative data on first year establishment (density and/or <br />frequency would be appropriate) and 3rd or 4th growing season cover, <br />species composition, production and woody density. The plan should <br />also commit to submittal of such data to the Division at permit <br />mid-term and permit renewal time. <br />~(1 <br />V `~ The plan for monitoring vegetation in the aspen reestablishment test <br />~J plots should be included in the application, and that data should also <br />be submitted to the Division at permit mid-term and renewal time. <br />3~ -6.~ ~ The applicant has proposed that vegetation monitoring be employed as a <br />means of documenting adequate fertility of replaced topsoils, as <br />~;~ ,' opposed to regular testing of replaced soils. Oetaii regarding how the <br />~, ~. \ monitoring program would address this concern should be provided. For <br />(~;~: example, if a 4th year revegetation stand does not meet reference area <br />'' _ (' production levels, would a soil sampling and, if necessary, a <br />,~f.~ l fertilization program be undertaken at that time, even though the 10 <br />year liability period would be reinitiated? <br />~;,~ ~~ Our concerns with the fertility status of replaced topsoils are <br />`~' ;primarily in regard to long term stockpiled soils. Is information <br />,. .~~~ 'regarding the source (live handle versus stockpiled) of soil analyses <br />? .:ti ~ ~ presented in Exhibit 23 available? If so, are there any significant <br />v ,,`,, differences between fertility levels of live handle and stockpiled <br />topsoils? <br />i,~ <br />Fish and Wildlife - Rules 2.04.11, 2.05.6(2) and 4.18 <br />1.~/ The applicant should commit to submitting all required wildlife <br />monitoring data to the Division at appropriate intervals (e. g. elk, <br />G~;.i passerine bird and raptor nest survey data should be submitted <br />annually). <br />
