to clarify that this is the case, and include an appropriate section addressing <br />success demonstration methods far the NH-1 Irrigated Hay I'?ropland area. <br />c} While the general plans presented in the twa sections conform with Rule 4.15.11 <br />r?qulrernents, presentation t? ?Mf,R ?f a detailed pr?toeol far dad. collection, <br />evaluation, and presentation is strongly advised, prior to initiation of data collection <br />for bond release prefer to the 1995 Band Release Guideline document}. <br />d? The t-test listed under item 3, on amended page 3? of Tab ?? is identical tv the <br />"general form" of the reverse null t-test as listed in Rule 4.15.11 ??}?c}. This ?s in <br />fact the enact form of the "one Sample" t?tet that would be employed if a <br />technical standard is involved. It is also the exact farm of the t-test rriployed if a <br />reference area is involved, and sample adequacy i achieved in the reference area, <br />where the Standard ("}? in the formula} is the reference area sample rr?ean prefer to <br />the 199 Bond Release guideline for further explanation}. However, in the event <br />that sample adequacy were not achieved in the reference area after 3? or mere <br />sample observations, a mare complicated two sample t-test, with Satterthwaite <br />corrected standard error and degrees of freedom would be warranted, to <br />demonstrate that the reclairr?ed area population mean is greater than 9o°Io of the <br />reference area population mean, at the So°I? level of statistical confidence. Please <br />Include a narrative commitment under Item of the statistical procedures <br />section, to clarify that, in the event that sample adequacy is not demonstrated <br />in the reference area, reverse null testing wn?ld employ atterthwaite <br />corrected two sample t-testing. <br />?. ?11?I? requested a revised Pren?ining Land Llse Map and corresponding narrative and <br />table, delineating and describing land use categories in corr?pliance with Rule 1,?4?71}, to <br />clear up confusion and inconsistencies in the Sections x.04,3 and Z.?4.10 of the <br />application, pertaining to the ?H?2 mine area <br />A new map was prepared and the narrative of section 2.4.3 was substantially revised. <br />The new reap aril text revisions are substantial improvements to the document, and the <br />clarity ofthe section is much Improved. Item Resolved. <br />7. ?I?R noted and operator had previously described coneerr?s regarding the high extent of <br />perennial Farb cover and low extent of perennial grass cover an the Dryland Pastureland <br />reference area Apparently, drought conditions since 1999 have resulted insubstantial die <br />off of grasses and increase in perennial fortis, operator is concerned that the high cover <br />provided by the (orbs rriay make demonstration of cover success for dryland pasture areas <br />diffcult. The operator conducted a search of the general area in the vicinity of the mine, <br />with the assistance of local NR?S and BL personnel, but reports that they were unable to <br />locate a preferable location for a dry pasture reference area, with the appropriate <br />combination of soils, vegetative type, and management. For the present, the current <br />dryland pasture reference area will be retained; no change is being proposed within TR-54. <br />Far the purposes afTR-54, the Item is Resolved. <br />3
