Sec. 35-125. Basis for wastewater service charges.

The wastewater service charge for the use of and for service supplied by the wastewater facilities of the City of Rolla shall consist of a basic user charge for operation and maintenance plus replacement plus sewer system reserve fund, and a surcharge.  (See Appendix "A")

      The basic user charge shall be based on water usage as recorded by water meters and/or sewage meters for wastes having the following normal concentrations:

      (a)   A five day, 20 degree centigrade (20oC) biochemical oxygen demand (BOD) of 200 mg/1.

      (b)   A suspended solids (SS) content of 250 mg/1.

      It shall consist of operation and maintenance costs plus replacement costs plus sewer system reserve fund costs and shall be computed as follows:

      (a)   Estimate the projected annual revenue required to operate and maintain the wastewater facilities, including a replacement fund for the year and a sewer system reserve fund, for all works categories.

      (b)   Proportion the estimated costs to wastewater facility categories by Volume, Suspended Solids and BOD, if possible.

      (c)   Estimate wastewater Volume, pounds of SS and pounds of BOD to be treated.

      (d)   Proportion the estimated costs of non-industrial users by Volume, Suspended Solids and BOD.

      (e)   Compute costs per 1,000 gallons for normal sewage strength.

      (f)    Compute surcharge costs per pound and BOD and SS in excess of normal sewage strength.

      A surcharge will be levied to all users whose wastewater exceeds the normal concentrations for BOD (200 mg/1) and SS (250 mg/1).  The surcharge will be based on water usage as recorded by water meters and/or sewage meters for all wastes which exceed the 200 mg/1 and 250 mg/1 concentration for BOD and SS respectively.  Section 35-129 specifies the procedure to compute a surcharge.

      That portion of the total user charge collected which is designated for operation and maintenance including replacement purposes as established in Section 35-126, shall be deposited in a separate non-lapsing fund known as the Operation, Maintenance and Replacement Fund and will be kept in two primary accounts as follows:

      (a)   An account designated for the specific purpose of defraying operation and maintenance costs (excluding replacement) of the treatment works (Operation and Maintenance Account).

      (b)   An account designated for the specific purpose of ensuring replacement needs over the useful life of the treatment works (Replacement Account).  Deposits in the replacement account shall be made annually from the operation, maintenance and replacement revenue in the amount of $272,189 annually.  (See Appendix "B")

      The adequacy of the wastewater service charge shall be reviewed annually by accountants for the City of Rolla and presented in their annual audit report.  The wastewater service charge shall be revised periodically to reflect a change in operation and maintenance costs, replacement costs, or the sewer system reserve fund.

      The City will review the user charge system every year and revise user charge rates as necessary to ensure that the system generates adequate revenues to pay the costs of operation and maintenance including replacement and that the system continues to provide for the proportional distribution of operation and maintenance including replacement costs among users and user classes.

      The City will notify each user at least annually, in conjunction with a regular bill, of the rate being charged for operation, maintenance including replacement of the treatment works.

      The volume of flow used for computing basic user charges and surcharges shall be the metered water consumption read to the lowest even increment of 100 gallons.

      (a)   If the person discharging wastes into the public sewer procures any part, or all, of his water from sources other than the City of Rolla Water System, all or a part of which is discharged into the public sewers, the person shall install and maintain, at his expense, water meters of a type approved by the public works director for the purpose of determining the volume of water obtained from these other sources.

      (b)   Devices for measuring the volume of waste discharged may be required by the public works director if these volumes cannot otherwise be determined from the metered water consumption records.

      (c)   Metering devices for determining the volume of waste shall be installed, owned and maintained by the person.  Following approval and installation such meters may not be removed, unless service is cancelled, without the consent of the city engineer.  (Ord. 2136, §2; Ord. 2886, §3; Ord. 3486, §2; Ord. 3881, §2)

Sec. 35-126. Basic user rate for metered users.

Each user shall pay for the services provided by the City based on his use of the treatment works as determined by water meters acceptable to the City.

User charges shall be based on water used during the current month.  If a user has a consumptive use of water, or in some other manner uses water which is not returned to the wastewater collection system, the user charge for that contributor may be based on a wastewater meters or separate water meters installed and maintained at the contributor's expense, and in a manner acceptable to the City.

On a monthly basis each contributor shall pay a user charge rate for operation and maintenance including replacement of $5.15 for 0 - 1000 gallons of water (or wastewater) and $5.15 per 1000 gallons of water (or wastewater) for each additional 1000 gallons as determined in a preceding section.

Any user which discharges any toxic pollutants which cause an increase in the cost of managing the effluent or the sludge from the City's treatment works, or any user which discharges any substance which singly or by interaction with other substances causes identifiable increases in the cost of operation, maintenance, or replacement of the treatment works, shall pay for such increased costs.  The charge to each such user shall be determined by the responsible plant operating personnel and approved by the city council

In the event of a user's failure to immediately comply voluntarily with the suspension order, the city engineer may take such steps as deemed necessary, including immediate severance of the sewer connection, to prevent or minimize damage to the POTW, its receiving stream, or endangerment to any individuals. The city engineer may allow the user to recommence its discharge when the user has demonstrated to the satisfaction of the city engineer that the period of endangerment has passed, unless the termination proceedings in Section 35-246 of this ordinance are initiated against the user.

(b) A user that is responsible, in whole or in part, for any discharge presenting imminent endangerment shall submit a detailed written statement, describing the causes of the harmful contribution and the measures taken to prevent any future occurrence, to the city engineer prior to the date of any show cause or termination hearing under Sections 35-241 or 35-246 of this ordinance. Nothing in this section shall be interpreted as requiring a hearing prior to any emergency suspension under this section. (Ord. 3183)

Sec. 35-258 Bypass.

(a) For the purposes of this section,

(1) "Bypass" means the intentional diversion of wastestreams from any portion of a user's treatment facility.

(2) "Severe property damage" means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production.

(b) A user may allow any bypass to occur which does not cause pretreatment standards or requirements to be violated, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provision of paragraphs (c) and (d) of this section. (c) If a user knows in advance of need for a bypass, it shall submit prior notice to the city engineer, at least ten (10) days before the date of the bypass, if possible.

(1) A user shall submit oral notice to the city engineer of an unanticipated bypass that exceeds applicable pretreatment standards within twenty-four (24) hours from the time it becomes aware of the bypass. A written submission shall also be provided within five (S) days of the time the user becomes aware of the bypass. The written submission shall contain a description of the bypass and its cause; the duration of the bypass, including exact dates and times, and, if the bypass has not been corrected, the anticipated time it is expected to continue; and steps taken or planned to reduce, eliminate, and prevent reoccurrence of the bypass. The city engineer may waive the written report on a case-by-case basis if the oral report has been received within twenty-four (24) hours.

(d) Bypass is prohibited, and the city engineer may take an enforcement action against a user for a bypass, unless:

(1) Bypass was unavoidable to prevent loss of life, personal injury, or sever property damage;

(2) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and

(3) The user submitted notices as required under paragraph (c) of this section.

(e) The city engineer may approve an anticipated bypass, after considering its adverse effects, if the city engineer determines that it will meet the three conditions listed in paragraph (d) of this section. (Ord. 3183)

APPENDIX "A" TO USER CHARGE ORDINANCE - (Actual Use Rate Structure)

This appendix presents the methodology to be used in calculating user charge rates and surcharges and illustrates the calculations followed in arriving at the first year's user charges and surcharges. The unit costs established in this appendix are based on estimates of expenses and loadings. The actual expenses and loadings that occur may differ from these estimates and certainly will change as time passes. Therefore, the unit costs must be reestablished whenever necessary to reflect actual expenses and loadings. Once the system is in use, the expenses and loadings can be determined from operating records and the unit costs can be adjusted based on these figures. The City of Rolla presently has 6,290 metered and 364 non-metered residential customers.
1.   Expenses: The total annual expenses associated with the treatment works, as defined in Sec. 35-124, are estimated as follows:
              Item                                                                       Annual Expenses
              Administrative                                                              $274,500
              Power                                                                          $250,000
              Labor (including fringe benefits)                                      $833,142
              Material Costs                                                               $314,949
              Replacement Costs (see Appendix "B")                            $272,189
              Debt Service                                                                 $1,115,000
              TOTAL                                                                         $3,059,780**

** Includes I/I costs.
2.   Allocation of Expenses: The total operation and maintenance including replacement expense is allocated to the appropriate pollutants in the following manner:
Annual $ to Treat Annual Flow                                     $1,223,912
Annual $ to Treat Annual BOD                                     $917,934
Annual $ to Treat Annual SS                                        $917,934

      3.     Loadings:
The initial hydraulic loading is estimated to be 1,064,068,420 gal/year.
The initial water usage (metered and non-metered) is estimated to be 594,132,039 gal/year.
The initial BOD loading is estimated to be 991,606.37 pounds/year.
The initial SS loading is estimated to be 1,239,507.97 pounds/year.

      4.     Unit Costs:
Initial unit cost for flow in (expressed in usage) $/gallons =
$1,223,912.00/594,132,039 = $0.0021
Initial unit cost for BOD in $/pound = $917,934.00/991,606.37= $0.926.
Initial unit cost for SS in $/pound = $917,934.00/1,239,507.97 = $0.741.

              The unit costs for BOD, SS and other Pollutants are to be inserted in Sec. 35-128 of the ordinance.

      5.     User Unit Charge: The user unit charge is calculated as following using the pollutant concentrations defining normal domestic wastewater in Sec. 35-124 of this ordinance.

              Unit charge = $2.06/1000 gal.
+ ($0.926 unit BOD charge) (200 mg/1 BOD) (.00834)
+ ($0.741 unit SS charge) (250 mg/1 SS) (.00834)
= $5.15/1000 gal.

Where:  Unit charge is in $/1000 gallon or $5.15/1000 gallon
Unit flow charge is in $/1000 gallon from paragraph 4
Unit BOD charge is in $/lb BOD from paragraph 4
Unit SS charge is in $/lb SS from paragraph 4
BOD is the normal domestic BOD strength in milligrams per liter (mg/1) as
defined in Sec. 35-124 of the ordinance.
SS is the normal domestic SS strength in mg/1 as defined in Sec. 35-124 of the ordinance.
and .00834 is a unit conversion factor.

              This total unit charge is to be inserted in Sec. 35-126 of the ordinance.

             An example of the calculation of a residential charge for a resident of the City of Rolla
follows:

              Six thousand (6,000) gallons usage @ $5.15/1000 gallons = $30.90/month sewer
user charge.

      6.     Extra Strength Users: For users who contribute wastewater that has greater strength than normal domestic wastewater, the user charge will be calculated as follows:

              Total monthly charge to extra strength user =
V ($5.15/1000 gal unit charge)
+ V ($0.926/1000 gal unit BOD charge ) (BODes-BODnd)(.00834)
+ V ($0.741/1000 gal unit SS charge) (sees - SEND)(.00834)

              Where:

                     V is the Volume of wastewater in 1000 gallons discharged by the extra strength
user during the month.
Unit flow charge is in $/1000 gal from paragraph 4
Unit BOD charge is in $/lb BOD from paragraph 4
Unit SS charge is in $/lb SS from paragraph 4
BOD is the normal BOD strength in milligrams per liter (mg/1) as
defined in Sec. 35-124 of the ordinance.
SS is the normal domestic SS strength in mg/1 as defined in Sec. 35-124 of the
ordinance.
and .00834 is a unit conversion factor.
es is extra strength
nd is normal domestic

              An example user charge calculation for an extra strength user of the City of Rolla treatment works follows:

              20,000 gallons usage, BOD = 300, SS = 350

              Charge = 20 ($5.15) = $103.00
+ 20 ($0.926) (300-200) (.00834) = $15.45
+ 20 ($0.741) (350-250) (.00834) = $12.36
= $130.81/month

      7.     Basic user rate for non-metered residential users: Calculation of charges to users in residential classes.

((Total Water Usage) X (User Rate))/Total Number of Residential Meters

 

              This average annual cost to be used for non-metered residential users and inserted in Section 35-127. 

      This Ordinance shall be in full force and effect as of the first billing of the Sewer and Water Charges after passage.  (Ord. 2950, §2; Ord. 3017, §2; Ord. 3082, §2; Ord. 3215, §2; Ord. 3267, §2; Ord. 3359, §2; Ord. 3418, §2; Ord. 3486, §2; Ord. 3530, §2; Ord. 3703, §2; Ord. 3770, §2; Ord. 3830, §2; Ord. 3881, §2; Ord. 3935, §1; Ord. 3966, §1; Ord. 4060, §1; Ord. 4117, §1, Ord. 4166, §1, Ord. 4234, §1, Ord. 4306, §1)
