<br />L4. REVISIONS REQUIRED <br />The fallowing items were identified during the review that rem~;re <br />revisions to the permit application. <br />1. Page No.2 of the permit application should be changed to show the new <br />mailing address of the Salt Creek Mining Company. Due to changes to Rule <br />2.03.4 that recesitly made, you will need to revise the identification of <br />interests portion of your application. Please note the attached rule change <br />labeled Attachment B and memo from Sandy Brown. Changes should be submitted <br />as replacement pages and submitted as a minor revision to the permit <br />application. <br />2. Page 2-21, concerning the design of the haul road, seems to imply that <br />the only design criteria that will be used for the construction of the haul <br />roads will be the size of the haul truck. Page 2-21 states that "Additional <br />tests and considerations will be made during the actual road improvement <br />effort so that the design and construction will be premised upon site <br />specific information. The improved road will be designed and constructed <br />pursuant to the criteria below." The design criteria given is weight, size <br />and wheel load for a haul truck. The Munger mine should add the following <br />to this section. "...pursuant to the criteria below and the design criteria <br />set forth in the performance standards of MLRD Rule 4.03.1 for haul roads, <br />final designs for the haul road will be submitted to the Division as a <br />technical revision." In this way it does not appear that the Division is <br />giving prior approval to haul road designs that may not meet the <br />performance standards of Rule 4.03.1. <br />3. Page 2-36 of the application refers to the Loma loadout surface water <br />control system. This portion of the application does not contain enough <br />information to evaluate the the effectiveness of the system as a small area <br />exemption. Rule 4.05.2 requires that all drainage from disturbed azeas pass <br />through a sediment pond, but allows the Division to grant exemptions from <br />this regm~irement ]f the operator can demonstrate that sedimentation ponds <br />and treatment fadlities aze not necessary for the drainage to meet the <br />effluent limitations of 4.05.2 and the applicable State and Federal water <br />quality requirements for downstream receiving waters. For the purpose of <br />this demonstration Salt Creek Mining should submit calculations to show <br />that the berm will contain all runoff from a 10 year 24 hour predpitation <br />event without discharging. The excess capacity above a 10 year event will <br />allow for water storage and eventual evaporation and infiltration between <br />predpitation events. Minimum design criteria should be submitted for <br />incprlion into the application. This should be submitted aS a minor <br />revision. Page 4-34 describes the sediment control structures on the Munger <br />portal bench. This portion of the application should be revised likewise. <br />IB. ADVISORY COMMENTS <br />The Munger Canyon Mine has been in temporary cessation since January 20, <br />1984. Rule 2.01.5(2) states that "a permit shall terminate if the permittee <br />has not commenced the surface coal mining and reclamation operations <br />covered by the permit within three years of the date of the issuance of the <br />permit" . The Division can grant extensions to the time of commencement of <br />operations, upon receipt of a written statement showing that such <br />3 <br />
