Comments: a -f) The MRF.bz s been exempt from waste discharge requirements by the California Regional Water Quatity. Control Board (CRWQCB) since 1994. Resolution Order No. 94-081 adopted by the C.RWQ,CB on February 2:3, 1994, granted the MRF a waiver from all waste.discharge requirements. It is:assumed:by the project applicants' the waiver is still in effect today. The storm water runoff from all areas except the wood storage and yard wastes composting area -will drain to anon -site retention pond. The retention pond will be sized to contain 200 percent of ithe computed volume of runoff from the 100 year/24-hour storm. The pond shall also be designed to empty by percolation and evaporation 100 percent of the required volume of; storage within 10 days. Storm -water runoff from the wood storage and compost concrete pad area will drain' to an on-site clay -lined evaporation pond. Because the evaporation pond .is conservatively sized for the 100 year/24 hour storm, it also meets the draft.prov(sions of Composting .Facilities Permitting Procedures and Enforcement (Section 17873, Chapter 3.1, Title 14 CCR) requiring the design to contain and collect twice the anticipated. volume of compgst leachate management system, which includes the evaporatigp. pond, teas beenidesigned to recycle the collected compost leachate to the compost processing area or to evaporate the compost leachate within 20 days.
