§ 30.211   RATES AND SURCHARGES
   (A)   
      (1)   On October 1, 2019, the below mentioned sewer rates shall be adjusted in accordance with the Consumer Price Index of the preceding year reported by the United States Government. In no event will there be any increase in the rates based upon the Consumer Price Index greater than three percent (3%). In the event the Consumer Price Index is less than one percent (1%), the rate will be adjusted at one percent (1%). The Consumer Price Index adjustment will be applicable only for a five- (5-) year period following the adoption of Ord. 01-2019.
      (2)   The rates to be charged by the Utility Commission for sewer services to the customers of the Utility Commission, effective March 1, 2019, based upon the recommendation of the Utility Commission, shall be as follows, to-wit:
   SEWER
   (Based on Water Consumption)
   SEWER
   (Based on Water Consumption)
In City Customers:
   First 1,000 gallons
$14.96
   Every 1,000 thereafter
$8.49
Out of City Customers:
   First 1,000 gallons
$21.18
   Every 1,000 thereafter
$8.96
Cooks Family Foods Water Rate:
 
   Wholesale rate
$2.44 per 1,000 gallons
 
   (B)   The charges for sewer user charges shall be levied on all users who discharge, cause, or permit the discharge of sewage into the public wastewater treatment system. Should there be users whose contribution to the system contains biological oxygen demand (BOD), suspended solids (SS), or ammonia nitrogen (NH3-N) in concentrations which exceed limits specified herein for such pollutants and who are permitted to make such contributions to the system by decision of the Superintendent of the city, then there will be charges known as excessive strength charges placed upon said users. These shall be imposed by the Superintendent of the Grayson Utility Commission such that a user discharging waste to the sewage works having an average biochemical oxygen demand (BOD) content in excess of two hundred seventeen (217) mg/l and/or an average SS content in excess of two hundred nine (209) mg/l and/or an average NH3-N content in excess of twenty-four (24) mg/l, with such user being required to pay a surcharge based upon the excess strength of its wastes. Such surcharges shall be billed in addition, to domestic level flows. Surcharges may either be billed separately or shown separately on the normal monthly sewer bill.
   (C)   Surcharge rates applicable to the user that has received permission from the Superintendent to contribute excessive sewage strength will be as follows:
 
SURCHARGE RATES
Parameter
Rate
BOD
$ 0.40/lb.
SS
$ 0.42/lb.
NH3-N
$ 1.45/lb.
 
   (D)   (1)   The excessive strength surcharge shall be based on the following formula, with the total applied to the monthly bill of affected users:
         [a(d-217) + c(f-24)] .00834 X g = Surcharge Payment
      (2)   Where formula components are as follows:
 
A.   Surcharge rate for BOD, in $/pound
B.   Surcharge rate for SS, in $/pound
C.   Surcharge rate for NH3-N, in $/pound
D.   User’s average BOD concentration
E.   User’s average SS concentration
F.   User’s average NH3-N concentration
G.   User’s monthly flow to sewage works in one thousand (1,000) gallons
 
   (E)   No reduction in sewage service charges, fees, or taxes shall be permitted because of the fact that certain wastes discharged to the sewage works contain less than two hundred seventeen (217) mg/l of BOD, two hundred nine (209) mg/l of SS, or twenty-four (24) mg/l of NH3-N. The formula for surcharges may not be construed to generate a negative charge either in any part or in total.
   (F)   Each user shall be notified, at least annually, in conjunction with a regular bill of the rate and that portion of the total charge which is attributable to operations and maintenance of the sewage system.
