WASTE DISCHARGE REQUIREMENTS EL RANCHO ROCK AND SAND, INC. , ET AL. SAN JOAQUIN COUNTY -2- 7. Excavated rock and sand will be processed at the plant by washing, crushing, rolling, conveying and screening. It is anticipated that up to 5% of the raw feed will be wasted as fines. Fines from the processing operations will be contained on-site by using a series of sedimentation/recycle ponds. The ponds will be designed and operated to provide containment from overflow for all washwaters and stormwater generated during a 24-hour storm event with a return frequency of 100-years. Fines will be periodically removed from the recycle ponds. Ultimate deposition of the fines will be next to the excavation area. 8. The Board adopted the Water Quality Control Plan, 2nd Edition, for the San Joaquin Delta Basin (5B) which contains water quality objectives. These requirements are consistent with that Plan. 9.
