d) Substantially alter the existing ❑ ❑ X ❑ drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surfaceirunoff in a manner which would result in flooding on-or off-site? e) Create'&contribute runoff ❑ ❑ X ❑ water'which would exceed the capacity of existing or planned storm water drainage systems or provide substantial additional sources of polluted runoff? f) Otherwise substantially ❑ ❑ X ❑ degrade.water quality? g) Place housing within a 100- ❑ ❑ ❑ X year flood hazard area as mapped on a federal Flood Mazarq..Boundary or Flood Insura,�,ce Rate Map or other flood.hazard delineation map? h) Place.Within a 100-year flood ❑ ❑ ❑ X hazard,area structures which would impede or redirect•(lood flows? i} Expose people or structures to ❑ ❑ ❑ X a significant risk of loss, injury or death involving flooding, including flooding as a result of the failUre of a levee or dam?

Comments: a-f) The MRF has been exempt from waste discharge requirements by the California Regional Water Quality Control Board:(CRWQCB) since 1994. Resolution Order No.94-081 adopted by the CRWQ>ti.B on February 23, 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 an on-site retention pond.The retention pond will be sized to contain 200 percent of-:the 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.provisions 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 compost leachate management system,which includes the evaporation pond,has been designed to recycle the collected compost leachate to the compost processing area or to evaporate the compost leachate within 20 days.
