This <br />should include, at a minimum, fertility status and major plant nu rients. <br />2.05.6 Mitigation of Surface Coal Mining Operation Impacts <br />2.05.6(3)(b)(iii) <br />The surface water quality monitoring should occur during the sno ell runoff <br />season and convective storm season. Quarterly monitoring is snap ropriate for <br />ephemeral streams. Four samples should be obtained from snowmelt and rainfall- <br />caused runoff and discharge mould be measured at the same time. <br />2.06 Requirements for Permits for Special Categories of Mining <br />2.06.8 S <br />Regarding Wyoming Fuels' request that the Division make a negative' determination <br />on the existence of an alluvial valley floor in the North Fork of Bolton Draw, <br />more information is required to make that finding: <br />1. A map of the unconsolidated alluvium, Unit 8, should be prepar~d on a scale <br />of 1:6000 or larger showing: <br />•~ A. Areas where the vegetation suggest subirrigation, and <br />B. Areas of alluvium containing streams. The applicant shouldbe aware that <br />ephemeral and intermittant channels are included in the definit'on of streams. <br />As per the OSM guidelines, only channels three (3) feet in bank~ull width <br />and 0.5 feet in bankfull depth need be mapped. <br />2. The acreage of areas containing a stream channel as defined above, alluvium, <br />and vegetation suggesting subirrigation should be estimated. <br />3. The applicant needs to discuss the regional irrigation practic~s on units of <br />equal or lesser size than the area determined in (2) above. <br />The applicant should contact the Division if clarification of any bf the points <br />listed above is needed. <br />
