TOTAL FLOW FROM CMSD
As owner of the treatment plants and disposal facilities, the Orange County Sanitation District
(OCSD) has developed flow coefficients for forecasting total daily dry weather (without storm
water inflow or infiltration) flow from a tributary area. 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. The property owner
is allowing the District to cut into the fence and make some modifications. Mike Kilbride
employees will be raising the manhole and adding a gate.
ELDEN PUMPING STATION ODOR CONTROL ANALYSIS
Mr. Carroll noted Staff is looking at cost effective processes to control odor including scrubbers,
additives, Little John Digester (pumped air through digester cylinder), superoxygenation,
hydrogen peroxide, cleaning wet well, masking and blocking agents.
