INDUSTRIAL COST RECOVERY

§ 52.090 COST RECOVERY FORMULA.

   (A)   Purpose. All industrial users shall pay that portion of all federal grant amounts expended upon the city’s sewerage treatment works subsequent to 3-1-1973, allocable to the treatment of their sewerage wastes, based upon the following formula set forth in division (B) of this section.

   (B)   Industrial cost recovery formula. Industrial cost recovery amounts based on each industrial contributor’s flow, BOD and SS, as compared to the design load of flow, BOD and SS. Each industrial contributor would then pay the federal grant amount allocated to each flow, BOD and SS according to the contributor’s percent of the design land, such as:

   a — percent federal grant — flow      =   $475,303.95

   b — percent federal grant — BOD      =   $136,898.03

   c — percent federal grant — SS      =   $136,898.03

   d — design flow                  =   0.650 MGD

   e — design BOD load               =   1105 lbs. per day

   f — design SS load                =   1430 lbs. per day

   g — useful life                  =   30 years

      (1)   Amount contributed for flow:

          a = cost/year/gallon = $24,374.56/MGD/year

          d × g

      (2)   Amount contributed for BOD:

          b = cost/year/lb. BOD = $4.13/lbs/day/year

          e × g

      (3)   Amount contributed for SS:

          c = cost/year/lb. SS = $3.19/lbs/day/year

          f × g

§ 52.091 LETTER OF INTENT.

Each letter shall also contain a statement of the industrial user’s intended period of use of the sewerage treatment works.

(1994 Code, § 52.081) (Ord. 263, passed 3-8-1976)

§ 52.092 BASES FOR USER’S COSTS.

   The industrial user’s cost for treatment of its wastes shall be based upon all factors which significantly affect the cost of the treatment works, including strength, volume and flow characteristics of the sewerage as defined and set forth § 52.002 of this chapter.

(1994 Code, § 52.082) (Ord. 263, passed 3-8-1976)

§ 52.093 ANNUAL PAYMENTS BY USERS.

   During the industrial cost recovery period defined herein, each industrial user of the sewerage treatment works shall pay is share of the total grant moneys expended divided by the recovery period years. The payments shall be made on an annual basis by each industrial user. The first payment by an industrial user shall be made no later than one year after the user begins use of the sewage treatment works.
