2.05.3 <br />sediment ponds. Ponds B and C are designed to contain a one year sediment <br />load which is less than the more typical three year sediment design load. Pond J <br />is designed to contain a two year sediment load. Therefore, the sediment from <br />the ponds may have to be removed more frequently. Sediment will be removed <br />from ponds B, C, J, K and F and the gob pile sediment pond no later than when <br />the ponds are 75% full of sediment. Markers will be installed in Pond F clearly <br />indicating the required sediment cleanout level and maximum water level that <br />could occur while still allowing ample storage for the design event. <br />(ii)(D) Sediment ponds B, C, J, K, F and the gob pile sediment pond will be <br />removed after the site has been reclaimed and the vegetation on the <br />reclaimed site is adequate to control erosion. Pond removal must be <br />authorized by the Division and the untreated drainage from the disturbed <br />area ceases to contribute additional suspended solids above natural <br />conditions. <br />None of the sediment ponds meet the size requirements of this section, <br />therefore this section is not applicable. <br />(b) The sediment ponds are considered temporary ponds and are designed to <br />meet the requirements of Rules 4.05.6 and 4.05.9. <br />(c) Not applicable. <br />(d) Collection ditches and diversion ditches have been designed to comply with <br />the requirements of rules 4.05.3 and 4.05.4. <br />Small Area Exemptions (SAE) <br />The locations of the small area exemptions are presented on Maps 20, 21-1, <br />21-3, 35, 36, 36a, 36b, 39, 40 and 42. The Applicant will monitor the flow <br />from the small area exemptions to assure compliance with 4.05.2(3). The <br />Applicant will use its best efforts to obtain samples. The samples will be <br />analyzed for pH, conductivity and total settleable solids. Samples will be in <br />compliance if they contain settleable solid levels of 0.5 ml/I or less and the pH <br />is greater than 6.5 and less than 9.0. <br />MR -168 2.05-41- 11/14 <br />
