Please explain or clarify this <br />sentence with regazd to the discussion of mitigation of impacts to fish and wildlife (Rule 2.05.6(2)(b). <br />'8. Since the submittal of pages 2.05-171 through 2.05-171.12 (rev. 2/24/99 and 8/27/99), technical <br />revision No. 32 has completely revised and replaced these pages.

Please submit these pages. nlo-r o-x <br />\` <br />~. On page 2.05-184.7 there is a significant difference between the predicted flooding of Fish Creek as a <br />result of subsidence between the mathematical model, 262 acres, versus 39 acres in the GEIv1COM <br />model for panel 13R. The comparison between the two models for the other panels are much closer. <br />Please explain the lazge difference between the two predictions. <br />13. Exhibit 4E-3, discusses subsidence predictions, impacts and monitoring of the energy spur (rail line) <br />and Fish Creek. Although this exhibit discusses potentially flooded areas of Fish Creek and its <br />associated alluvial valley floor, resulting from subsidence, there is no discussion of potential impacts <br />to adjacent land that may be saturated as a result of subsidence. Please include a discussion of <br />impacts to potentially saturated areas resulting from subsidence. <br />C:/jhb/C82056/PROS/jhbadgl.doc ~ `YI 2 3/10100 <br />
