The basis for the industrial cost recovery rates and charges included in Section 9-126, above, are as follows:
a. Total estimated federal grant amount to be awarded for the plant improvements and interceptor sewers under Project Number C-180474 01 amounts to approximately $1,162,050.00
b. The consulting engineers estimate that an equitable distribution on a percentage basis of the total cost of construction and equipment included in the treatment plant project would be as follows:
Treatment of sanitary waste flow 40%
Treatment of suspended solids 25%
Treatment of BOD 35%
c. The design capacity of the treatment plant is as follows:
Flow: Annual design flow capacity of 365 M.G.
Suspended Solids: Design capacity 200 mg/l, times annual flow
capacity 365 M.G., times weight will result in
608,820 # average annual design capacity.
capacity 365 M.G., times weight will result in
608,820 # average annual design capacity.
Biochemical Oxygen Demand: Design capacity 240 mg/l, times annual flow
capacity 365 M.G., times weight will result in
729,971 # average annual design capacity.
capacity 365 M.G., times weight will result in
729,971 # average annual design capacity.
d. Industrial cost recovery period will be thirty (30) years.
e. Average annual basis for the cost recovery charge will amount to $38,735.00 ($1,162,050.00 federal grant, divided by thirty (30) years recovery period).
f. Total annual basis for the cost recovery charge allocated to treatment functions, is as follows:
Treatment of waste volume ($38,735.00 x 40%. = $15,494.00)
Treatment of suspended solids ($38,735.00 x 25%. = $ 9,683.75)
Treatment of BOD ($38,735.00 x 35%. = $13,557.25)
g. The industrial cost recovery rates for the treatment charges are computed on the basis of the annual functional costs of treatment, divided by average annual design capacity in the following manner:
Treatment of sanitary waste volume:
Annual functional cost of $15,494.00 divided by annual capacity 365 M.G., equals $.042 per 1,000 gallons.
Treatment of suspended solids:
Annual functional cost of $9,683.75 divided by annual capacity of 729,971 pounds equals $.0159 per pound.
Treatment of biochemical oxygen demand:
Annual functional cost of $13,557.25 divided by annual capacity of 729,971 pounds equals $.0186 per pound.
h. The rates computed in subsection (g) above, would result in total recovery of the federal grant amount if all users were subject to the industrial cost recovery requirements, and provided that the treatment plant was operated at capacity during the cost recovery period. Therefore, these rates will ensure that each industrial user will pay only that portion of the federal grant amount applicable to the costs of the treatment facilities actually utilized to treat industrial wastes, as determined by each industrial users flow and pollutant loadings.
