SECTION III - STATUS OF STIPULATIONS The Settlement Agreement between P8M and the Division dated November 19, 1987 reduced the list of stipulations to three. They are as follows: Stipulation No. 1 THE PERMITTEE MUST SUBMIT TO MLRD THE DESIGNS FOR THE MOFFAT AREA SEDIMENT PONDS AT LEAST SIX MONTHS PRIOR TO CONSTRUCTION, AND RECEIVE APPROVAL FOR THE PROPOSED DESIGN BEFORE COM1~ NCING CONSTRUCTION OF THE PONDS OR MINING IN THE MOFFAT AREA. THESE DESIGNS WILL REFLECT CURRENT REGULATORY DESIGN CRITERIA AND APPROVAL WILL BE CONTINGENT ON INFORMATION DEMONSTRATING THAT THE PONDS OUTFLOW WILL MEET EFFLUENT LIMITATIONS. Stipulation No. lc THE APPLICANT SHALL SUBMIT DESIGN DATA FOR EACH OF THE MOFFAT AREA SEDIMENTATION POND INFLOW DITCHES. THIS INFORMATION SHALL INCLUDE EVIDENCE THAT DITCH SLOPES WILL PROVIDE POSITIVE DRAINAGE TO THE PONDS WITH ACCEPTABLE VELOCITIES. THE INFORMATION SHOULD ALSO DEMONSTRATE THAT BERMS TO BE CONSTRUCTED WILL NOT SIGNIFICANTLY IMPOUND WATER. Stipulation No. 3 PRIOR TO MINING IN THE MOFFAT AREA, THE APPLICANT SHALL DEMONSTRATE, BASED UPON ON-THE-GROUND PERFORMANCE, THAT THE CONVEX LOWER SLOPES DO NOT CAUSE EXCESSIVE RILLING AND GULLYING OR THAT RILLING AND GULLYING ON THESE SLOPES CAN BE CONTROLLED. IF THE APPLICANT'S EFFORTS TO CONTROL RILLING AND GULLYING IN THE AREAS RECLAIMED PROVE UNSUCCESSFUL, THE APPLICANT WILL REDESIGN THE POSTMINING TOPOGRAPHY TO ELIMINATE THE CONVEXITY FROM THE LOWER PORTIONS OF THE SLOPE. The Division has received Permit Revision 1 (PR1) which addresses proposed mining in the Moffat area. This revision submittal includes discussion on sedimentation pond design (Stipulation No. 1) and the collection ditch system (Stipulation No. lc). The concerns upon which Stipulation No. 3 was based have been addressed in PR1. In this revision submittal mining will occur updip in 100 foot wide pits. Subsequent back filling and grading plans submitted appear to adequately answer Stipulation No. 3. -4-
