• The County Utility staff anticipated that regulations were forthcoming during the design of the Central Region expansion, now under construction. A twenty (20) year present worth analysis demonstrated that the cost of an onsite sodium hypochlorite generation system was approximately equal to the scrubbed gas chlorine system. When Central Region is completed, the onsite system will effectively eliminate the chance of an accidental chlorine release, thus Providing increased safety to the surrounding residents. Beginning November 30, 1998, a four-day pilot project was conducted to determine the suitability of a particular type of on-site generation system, new to the market supplied by E.K. Phelps. The results were encouraging and the Department of Utility Services' staff is pursuing a lease/purchase agreement with the supplier to be brought back to the Board for consideration. The North Beach Reverse Osmosis Plant conversion project will also, likewise, incorporate an on-site chlorine generation system. Bids for this project were opened on December 10, 1998. As stated earlier, risk management plans and accidental release prevention programs are required to be submitted to EPA by June 21, 1999. Since some County facilities are located in or near residential areas or schools, the County may want to consider further conversion to alternative systems as part of the plans. Such conversions, if promptly executed, can reduce the RMP scope significantly. Preliminary Task Team suggestions are as follows: 1. Fast-track the lease/purchase of on-site generation units for up to three wastewater treatment facilities, utilizing, in part, deduct change order monies made available through Change Order No. 3, approved by the Board of County Commissioners on August 25, 1998. (Please see attached copy of agenda item and minutes). 2. Develop a work authorization with the County's waxer consultant, Camp Dresser and McKee, Inc., to provide Consulting Services on an as -needed basis, for analysis of alternative disinfection systems or potential safety measures, to be brought back to the Board for consideration. The County's Emergency Management Services Department has reviewed and concurs with the Task Team approach. (Please see the copy of memorandum dated December 4, 1998). The staff of the Department of Utility Services recommends that the Board of County Commissioners approve the task -team's preliminary recommendations and allow staff to fast- track the RMP development, returning to the Board with the appropriate work authorizations and agreements.
