The revised Drainage Control P should also address the long-term stabilization of unstable ors nificantly eroded portions of the re ated Bull Seep and Bull Seep Slough Channel within the permit area • ~ well as restoration of the p' ometric surface in such areas to the ambient levels that tnay have occurred prior May 5, 2001. Suc plan should include a plan view map showing the location of all planned drainageway , culverts, s ways, or other such hydraulic structures; specific locations of existing drainageways requirin it stabilization, restoration, or reclamation: cross sectional engineering designs to verify the proper siz' each drainageway, culvert, spillway, or other such hydraulic structure; hydrologic inputs • calculan s to verify the proper sizing of each drainageway, culvert, spillway, or other such hyd tic structure; spe 'fic plans and engineering designs for long-term stabilization of unstable or sign' candy eroded areas; spe ' is plans and engineering designs for restoration of the piezome[ric surface i areas where significant channel wncutting has occurred; an estimate of pit inflows and dewatering mping rates; an explanation of how mt waters from pit dewatering, baseflow contributions from ~' Creek and Bull Seep, and runoff waters gener d both within the permit area and entering onto the ermit area will be managed; an explanation of the ma 'mum expected volume and velocity of m e water, runoff water, and baseflows to be discharged offsite the Bull Seep Slough; an expected t' e-schedule for when various stabilization, restoration, or reclamat n measures will be comp) d; and itemized costs for the installation of each stabilization, restora[io or reclamation measure to b employed.

Although no[ specif-icall equired, the revised Drainage Control Plan may also include measures to address the long-term stabiliz 'on of unstable or significantly eroded portions of the Bull Seep Slough channel outside the permit area as we as restoration of the piezometric surface in such areas to the ambient levels that may have occurred or to Mayy 5, 22001. ~~~~ y ~ Q.~17 (((Submit a plan that considers current hyd ologic conditions and is designed to minimize on-site erosion and offsite damage. Such plan must be submitted by November 29, 2001 with the provision that the operator may request an extension for good cause shown and demonstrating that they have made a good faith effort in working with the Urban Drainage & Flood Control District and other parties to meet the deadline.)))
