The culvert designs in the permit depict several multiple culverts for a road <br />crossing. In all cases where the multiple culverts are used, the combined end areas <br />are greater than 35 square feet. Rule 4.03.1(4)(e)(i) requires all culverts with end <br />areas greater than 35 square feet be designed to convey flows from the <br />20- year -24 -hour storm. The applicant has complied with this regulation. <br />The applicant has proposed that certain haul road segments be retained in reduced <br />configuration for post- mining ranch roads, with other haul roads to be reclaimed to <br />AOC and revegetated. Those road segments proposed to be reduced to a 20 foot <br />travel width to replace pre- existing ranch roads include the Mine Entrance Haul <br />Road (MEHR), and segments or all of Haul Roads A, G, F, H, J, K, and L. The <br />applicant has also proposed to retain the Ridgeline Access Road, to connect Road G <br />with proposed permanent road segments in the reclaimed "A" Pit area and the <br />South Extension Area, and the Oil Well Access Road. Several light use roads are <br />also proposed for permanent retention. All currently approved permanent roads are <br />shown on Exhibit 20 -2 of the permit application package. <br />Based on review of Technical Revision 42 (TR -42), the Division determined that <br />written landowner requests required by Rules 4.03.1(1)(f)(ii) and 4.03.2(1)(g)(ii) <br />had not been provided for various haul road and access road segments proposed for <br />permanent retention. The following stipulation (Stipulation 32) was attached to the <br />Division's approval decision for TR -42, and the stipulation remains in effect. <br />STIPULATION 32 <br />FOR PERMANENT ROAD RETENTION ON RECLAIMED LANDS, THE <br />PERMITTEE WILL SUBMIT, WITHIN A COMPLETE REVISION <br />APPLICATION, DEMONSTRATION OF COMPLIANCE WITH 4.03.1(1)(f) <br />OR 4.03.2(1)(g) AS APPLICABLE. THE DEMONSTRATION WILL <br />INCLUDE COPIES OF SIGNED LANDOWNER REQUESTS FOR ROAD <br />RETENTION FROM EACH AFFECTED LANDOWNER. ALL ROADS OR <br />SEGMENTS OF ROADS REQUESTED FOR RETENTION WILL BE <br />IDENTIFIED CONSISTENT WITH DESIGNATION IN THE PERMIT <br />APPLICATION (HAUL ROAD G, RIDGELINE ACCESS ROAD, OIL WELL <br />ACCESS ROAD, ETC.). THE ROAD RETENTION DEMONSTRATION <br />WILL BE SUBMITTED TO AND APPROVED BY THE DIVISION PRIOR <br />TO APPROVAL OF PHASE 1 BOND RELEASE FOR ANY RECLAMATION <br />PARCEL THAT INCLUDES A ROAD OR ROAD SEGMENT TO BE <br />RETAINED FOR THE POSTMINING LAND USE. <br />Seneca II -W Findings Document 18 C- 1982 -057 <br />Permit Revision No. 6 January 6, 2012 <br />
