OCSD has converted total flows from residential and other land uses into a flow coefficient related directly to population. The flow coefficient as established in 1997 by OCSD is 118.2 gallons per capita per day (gpcd). Using a District population of approximately 116,700 the flow from the District is: CMSD total daily dry weather flow = 118.2 gpcd x 116,700 population 13/8 mgd (million gallons per day) = 86.5 x 116,700 = 10.1 mgd PIERCE STREET ANNEX, 330 E. 17TH STREET A letter was presented from Attorney Matthew W. Davis, Parker Stanbury LLP; representing Douglas Adsit of Pierce Street Annex with regard to the Food Service Establishment grease interceptor conditional waiver. The objection is to the CMSD classifying them as a business emitting fats, oils and grease. The letter states they are not a restaurant and do not advertise themselves as a restaurant. The complaint was that the Pierce Street Annex was classified by the District as a business emitting fats, oils and grease. District Staff sent a response to the letter stating the background of the State of California Waste Discharge Requirements Order, and defining the District's Fats, Oils and Grease (FOG) Control Program. The response informed the attorney the District will issue a Conditional Waiver of FOG control measures at this time and should the owner still object to this classification, he may appeal the decision in writing to the CMSD Board of Directors. 819 -823 GOVERNOR Mr. Carroll provided an update on a manhole that was buried under a fence.
