amend the sections as appropriate. <br />12. Paragraphs V.J.3(e) and (g) are out of date, and (h) is no longer required, due to <br />the inclusion of specific sample adequacy formulas and hypothesis tests within <br />Rule 4.15.11. Please amend (e) and (g) on page V-64 to replace reference to <br />the guideline with reference to Rule 4.15.11, and delete the outdated <br />paragraph (h). <br />13. The wording of Item (c) on page V-61 could be interpreted in different ways, but <br />we assume what is intended is that perennial herbaceous production in the <br />revegetated area would be compared to perennial herbaceous production in the <br />reference area (an "apples to apples" comparison). Please amend the <br />language for clarification. <br />14. Additional detail is requested regarding the "adjacent undisturbed area" <br />comparison approach/ paired transect sampling technique described in Section <br />V.J.3(d), on page V-63. The paired sampling approach with adjacent site as <br />reference area is conceptually distinct from the independent sample approach <br />typically employed in reclaim area/reference area comparisons. For small and <br />linear disturbed sites as proposed in the permit, the approach would appear to <br />be a logical and valid method of disturbed/undisturbed area comparison. The <br />general form of the statistical tests associated with paired sampling is consistent <br />with the tests set forth in Rule 4.15.11, but the applicable terms differ (e.g. <br />means and variances used in paired sample statistical testing are means and <br />variances of the population of differences between paired sample observations, <br />rather than the means and variances of individual observation values used in the <br />case of independent samples). Please describe in more detail, the following <br />approaches and procedures applicable to paired sampling: <br />Sampling approach (e.g. random or systematic) employed to ensure <br />unbiased selection of reclaimed area transecUquadrat locations, <br />within logically grouped bond release blocks of drill sites or small & <br />linear features; <br />Minimum number of transect/quadrat pairs per bond release block <br />(15 for "standard null" and 30 for "reverse null" comparisons), and <br />specific form and terms for sample adequacy formula applicable for <br />"standard null" comparison, and; <br />Specific form, terms, and null hypothesis for the one sample t-test, <br />applicable to "standard null" and "reverse null" comparisons. <br />13 <br />
