h. EROSION AND SEDIMENT CONTROL REQUIREMENT #7 STABILIZATION OF TEMPORARY CONVEYANCE All temporary on-site conveyance channels shall be designed, constructed and stabilized to prevent erosion from the expected velocity of flow from a 2-year, 24 hour frequency storm for runoff volumes expected during the construction phase. Stabilization adequate to prevent erosion of outlets, adjacent steambanks, slopes and downstream reaches shall be provided at the outlets of all conveyance systems. i. EROSION AND SEDIMENT CONTROL REQUIREMENT#8 STORM DRAIN INLET PROTECTION All storm drain inlets made operable during construction shall be protected so that stormwater runoff shall not enter the conveyance system without first being filtered or otherwise treated to remove sediment. j. EROSION AND SEDIMENT CONTROL REQUIREMENT#9 UNDERGROUND UTILITY CONSTRUCTION The construction of underground utility lines shall be subject to the following criteria: 1. Every effort shall be made to close utility lines by the end of the day; 2. Where consistent with safety and space considerations, excavated material shall be placed on the uphill side of trenches; and 3. Trench dewatering devices shall discharge into a sediment trap or sediment pond. k. EROSION AND SEDIMENT CONTROL REQUIREMENT#10 CONSTRUCTION ACCESS ROUTES Wherever construction vehicle access routes intersect paved roads, provisions must be made to minimize the transport of sediment (mud) onto the paved road. If sediment is transported onto a road surface,the roads shall be cleaned thoroughly at the end of each day. Sediment shall be removed from roads by shoveling or sweeping and be transported to a controlled sediment disposal area. Street washing shall be allowed only after sediment is removed in this manner. 16
