9-1-10: RATES:
   A.   User Rates: The town council will establish and change the wastewater rates and charges by resolution after notice and hearing as provided in sections 69-7-111 and 112, Montana Code Annotated (1999).
   B.   Industrial Waste: Industrial wastes hereinafter being established in the town shall be charged the same monthly rates or shall have a rate contingent upon the volume of sewer discharged, the BOD, oil and grease, and suspended solids concentration in relation to the standard domestic concentrations. The assumptions for standard domestic BOD loading will be two hundred fifty milligrams per liter (250 mg/l), two hundred fifty milligrams per liter (250 mg/l) for suspended solids, twenty five (25) milligrams per liter (25 mg/l) for oil and grease, and a residential home per day discharging rate of three hundred fifty (350) gallons. The following formula shall apply:
 
 
Industrial Rate =
$15.45 + $15.45 ( Excess V) + (V x Excess BOD x $1.14 K1)
 
V
+ (V x Excess SS x $1.14 x K1) + (V x Excess oil and grease x $2.28 x K1)
 
$1.14 is the dollar per pound charge for BOD
$1.14 is the dollar per pound charge for SS
$2.28 is the dollar per pound charge for oil and grease
K1 is a constant equal to 8.33 x 10-6 which converts the units to dollars per month.
V is the monthly volume in gallons, equal to 10,500 gallons.
Excess V is the monthly sewage flow from industry in excess of 10,500 gallons.
Excess BOD is the monthly BOD concentration greater than 250 milligrams per liter.
Excess SS is the SS concentration greater than 250 milligrams per liter.
Excess oil and grease is the oil and grease concentration greater than 25 milligrams per liter.
   C.   Disputes: The rates, charges and rentals hereinabove specified shall be deemed prima facie fair, reasonable and equitable. In any case where any contention is made that said rates are unfair, inequitable, or unreasonable, the party objecting thereto shall apply to the town superintendent, stating the facts and grounds of complaint, and the town superintendent shall investigate and report with recommendations to the town council. The town superintendent may also report to said town council any cases where the amount or character of the sewage from any plant, building, or premises is such that collection and disposal thereof is substantially more expensive than average sewage, and give recommendations as to higher rates to be imposed for the collection and disposal of sewage. The town superintendent shall consider each and all of such complaints and reports, and communicate his findings in respect thereto to the town council within one month after the filing of such complaint. The town council shall have the right to order public hearings as to any such matter, and if convinced that an adjustment of sewerage rates or charges for such plant, building, or premises is necessary to provide equality with those charged to others, it shall so provide by law amendatory hereto.
   D.   Special Agreement Or Arrangement: No statement contained in this chapter shall be construed as preventing any special agreement or arrangement between the town and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the town for treatment.
   E.   Liability For Charges: The owner of each premises to which wastewater service is available from a main line owned or operated by the town shall be liable for payment of the charge hereinabove prescribed. (Ord. 13-001, 7-11-2013)
