<br />(e) Sample adequacy for all measurements will be determined using the appropriate formula <br />found in Part 4 of DMG's "Guidelines Regarding Selected Coal Bond Release Issues". <br />(f) Reference site data obtained during monitoring will be evaluated to determine range <br />condition following NRCS guidelines. <br />(g) Reclamation areas will be compared to their appropriate reference areas (vegetative cover <br />and herbaceous production) or technical standard (diversity and woody shrub density). <br />Revegetation success will be determined by comparing reference areas to revegetated <br />areas (Rule 4.15.7(4)(a)). The statistical test used in the comparison will be consistent with <br />the methods described in Part 4 of DMG's "Guideline Regarding Selected Coal Bond <br />Release Issues". <br />(h) As an alternative to testing the null hypothesis discussed in DMG's 'Guideline Regarding <br />Selected Coal Bond Release Issues' reverse-null hypothesis testing may be used. Prior to <br />using the reverse-null approach the DMG will be contacted to provide appropriate guidance. <br />V.J.4 Literature Cited (Sections I and J) <br />C-b Shale Oil Project. 1976.
