Harvest-Lathrop Composting Facility - 9- 7 February 2018 San Joaquin County 2) Keep daily records of weather conditions, the elevation of compost wastewater in the detention ponds, daily precipitation totals (24-hour period), and submit such records as part of the annual report and made available to Central Valley Water Board staff upon request; 3) Keep records which are part of the annual report and made available to Central Valley Water Board staff upon request on the date, quantity (gallons), and disposal method (i.e. dust control and compost wastewater removed from the detention ponds to temporary storage tanks necessary or off-site trucking of wastewater to a wastewater treatment plant to lower the detention pond level to below Action Level 2); and 4) Summarize the records kept including photographs taken during the Action Level 1 and Action Level 2 response in the annual report required by the General Order. e. The Discharger is limited to application of wastewater pond water for dust control purposes to areas where low permeability working surfaces have been installed and drainage from those surfaces is directed to the wastewater detention Pond 1 and Pond 2. 7. COMPLIANCE WITH COMPOST WASTEWATER DRAINAGE CONVEYANCE STRUCTURE SPECIFICATIONS The General Order provides minimum specifications for design, construction, and maintenance of Tier II Facility drainage ditches. Drainage ditches must be capable of conveying all precipitation and runoff from a 25-year, 24-hour peak storm event at a minimum, and have a hydraulic conductivity of 1.0 x 10-5 centimeters per second (cm/s) or less. The General Order also requires that berms/curbs and other drainage conveyance systems be designed, constructed, and maintained to manage, contain, and/or redirect precipitation flows from a 25-year, 24-hour peak storm event at a minimum. The Discharger stated in the 2018 Revised Final Technical Report that they shall comply with the General Order requirements for drainage ditches used in composting operations including but not limited to designing and constructing such conveyance structures with minimum six-inch thick Portland cement concrete. Therefore, all drainage ditches shall be constructed using minimum six-inch thick Portland cement concrete as shown in Attachment D, Drainage Ditch Details. The Discharger proposes to construct run-on/runoff control berms using earthen fill as shown in Attachment D, Section C-C. The final materials and size shall be determined during submittal of a final Design Report which prevents at a minimum run-on and run-off from a 25-year, 24-hour peak storm event, adequately protected from erosion, and must not cause, threaten to cause, or contribute to conditions resulting in contamination, pollution, or nuisance. 8. COMPLIANCE WITH CALIFORNIA ENVIRONMENTAL QUALITY ACT (CEQA) To fulfill requirements imposed by the California Environmental Quality Act ("CEQA") (Pub. Resources Code, § 21000 et seq.), San Joaquin County, acting as Lead Agency issued a Notice of Determination (NOD) on 11 April 2012 finding that the mitigated negative declaration that the mitigated negative declaration (See SCH #2012022021) adding urban green waste (including some food waste handling activities) to an existing agricultural waste composting facility is consistent with the Project proponent's existing conditional use permit
