SE? 09 1996 Planning Director City of Carlsbad 1200 Elm Avenue Carlsbad, CA 92008 CITY OF CAFltSf3P.D Planning Depxtnent Dear Don : This letter is in response to your request for ad- ditional information concerning the Encina Power Plant Water Treatment Facilities. Question 1: Wnat is the volume'of water being discharged? \ Answer: The amount of water discharged into the -. _-- ponds will vary from day to day due to the fact that extended power plant operatior,s require varying axounts of fresh water. Our NPDES permit #CA 0001350 application to the California Regional Water Quality Control Board for Encina Stipulates the following: 1. Extended (zeta1 cleaning) discharge waters will not exceed 21,000 gpd. 2, Low vol-une discharge water will not exceed 135,000 gpd. It should be noted that boiler blowdown, which is not to exceed 90,000 gpd, has Eot been included in the above quantities. We will attempt to recover and reuse as much of this water as possible. :!-* Question 2: What is fresh water used for in the __ Lr) dLerinal power plant proccss? Answer: Fresh water is used for: 1. Boiler fee2waker. This prepar3d water replenishes boiler blowdswn and s~~plies steam atomization (for stack No control). X 2. Circulating water pimp lubrication. 3.
