I r.l ') I ':.. "'" TUESDAY JANUARY 10, 1984 years. In addition, Mr. Crush presented the following general notes or comments which relate to the data identified as "Table 1" and Table 2"; We have made the assumption that regardless of whether or not the City's plant is expanded beyond the present 6 MGD, the additional sludge stabi- lization and odor control improvements will be added to effectively treat the industrial wastes by increasing sludge detention time to conform with good design practices and to maximize odor abatement. The following comments are based on three significant assumptions as to possible actions of the Henry County Public Service Authority. They are: (1) Based on the 12/19/83 meeting, it appears the P.S.A. will not at this time share in the expansion from 6 to 8 MGD of the City's W.P.C.P. (2) The H.C.P.S.A. will honor the terms of the existing 1974 Wastewater Agreement and share proportionally in the cost of the digester and odor control improvements. The P.S.A. may, however, seek additional clarification as to capacities and cost. (3) The H.C.P.S.A. corrected buy-in cost to the City for use of the Upper Smith W.P.C.P. is now $1.07 per gallon (Option 5, December, 1983). This cost could be subject to change based on further negotiations and actual construction bids. A comparison of the estimated capital costs shows approximately a $0.07 dif- ference per gallon capacity between the two basic alternatives and a $0.06 difference per gallon capacity in the two 20 year alternatives. Present operational and maintenance costs per 1,000 gallons for waste treated at the two plants are approximately the same. However, little analysis has been made of the impact the diversion of the Jones Creek flow will have on the sludge handling and other operations and maintenance costs at either plant. This is an important consideration since the total life-cycle of any facility is usually categorized as 2 to 5 percent design costs; 35 to 45 percent construc- tion costs; and 50 to 60 percent operation, maintenance, and repair costs. If the City elects to buy-in initially to the P.S.A. 's Upper Smith Plant to the maximum capacity needed of 2.3 MGD, the City would be faced in the future with providing for an additional projected need of 1.33 MGD. Since the City's W.P.C.P. cannot be economically expanded by this increment, the City would want assurance by the P.S.A. of their eventual intent to buy-in to the City's 2 MGD expansion - or the City would have to expand its plant from 6 MGD to 8 MGD unilaterally. In fact, until the County's Marrowbone Plant became a topic of discussion, it was agreed that both jurisdictions would share in the two-plant concept (H.C.P.S.A. Upper Smith Plant at 8 MGD and the City's W.P.C.P. as 8 MGD). This would supply the foreseeable needs of the area for the next 20 years. The only point of contention centered around which plant to expand first.
