served directly or indirectly, by the public sewer systems and
facilities of The Metropolitan St. Louis Sewer District (Bonfils
Watershed).
WHEREAS, The Metropolitan St. Louis Sewer District
desires to establish surcharges on a uniform District-wide basis
for the removal of suspended solids (SS) and biochemical oxygen
demand (B.O.D.) exceeding normal sewage discharge as defined in
Ordinance No. 2289, adopted May 3, 1972,
NOW, THEREFORE, BE IT ORDAINED BY THE BOARD OF TRUSTEES
OF THE METROPOLITAN ST. LOUIS SEWER DISTRICT:
Section One. Unless the context specifically indicates
otherwise, the meaning of the terms used in this ordinance shall
be as follows: SS = Average concentration of suspended solids in water or waste in milligrams per liter. B.O.D. = Average concentration of 5-day B.O.D. in water or waste in milligrams per liter. 350 = Concentration of total suspended solids in "Normal" sewage in milligrams per liter. 300 = Concentration of 5-day B.O.D. in "Normal" sewage in milligrams per liter. 8.34 = Weight in pounds of one gallon of water. F = Average flow of water or waste express in million gallons per day. 182.5 = The number of days in each semi-annual period. 0.95 = Factor allowance for 95 percent degree of

purification. $80.00 =The cost to the District in dollars per dry ton for removal of suspended solids. $80.00 =The cost to the District in dollars per ton for removal of 5-day B.O.D. 2,000 = The number of pounds per ton.
Section Two. The general requirements for
determination of surcharge applicability in The Metropolitan St.
Louis Sewer District (Bonfils Watershed), and the reporting,
compilation, and use of analytical data and other pertinent
information for said surcharges shall be as follows:
1. The person subject to surcharge is one whose water
consumption is equal to or exceeds fifty thousand cubic feet 500
Ccf) in any six month period.
2. Each person subject to surcharge shall submit to
the District on forms supplied by the District as stated in
Ordinance No. 2289, adopted May 3, 1972, a certified statement
concerning strength and volume of wastewater discharged into the
sewers or sewer works of the District or into any sewer connected
thereto. The analytical data submitted thereby based on Standard
Industrial Classification requirements shall be obtained from
samples collected in accordance with standard accepted procedures
from the manhole or adequate place described in said Ordinance No.
2289 at a time period representative of normal operational
conditions and utilizing accepted analytical procedures.

3. Analytical data reported by the person discharging
subject wastewaters will be considered current for each subsequent
billing period until such data is reported inaccurate and replaced
by updated certified data by said person. The results of routine
scheduled sampling and analyses by the Industrial Waste Division
of the District may bc used in lieu of data reported by said
person if such data is found to be not current or in error.
Section Three. In The Metropolitan St. Louis Sewer
District (Bonfils Watershed), a surcharge shall be collected from
any person discharging or responsible for the discharge into the
public sewerage system of suspended solids (SS) whose average
concentration exceeds 350 mg/l with said surcharge calculated for
each semi-annual billing period according to the following
formula, to wit: Semi-Annual Charge=(SS-350) x 8.24 x F x 182.5 x 0.95 x $80.00 2000
Section Four. In The Metropolitan St. Louis Sewer
District (Bonfils Watershed), a surcharge shall be collected from
any person discharging or responsible for the discharge into the
public sewerage system of biochemical oxygen demand (B.O.D.) whose
average concentration exceeds 300 mg/l with said surcharge
calculated for each semi-annual billing period according to the
following formula, to wit: Semi-Annual Charge =(B.O.D.-300)X8.24 x F x 182.5 x 0.95 x $80.00 2000
Section Five. AlI surcharges in The Metropolitan St.
4
Louis Sewer District (Bonfils Watershed) shall be calculated
separately for each premise using wastewater flow proportioned
average suspended solids concentration (SS) and/or average
biochemical oxygen demand concentrations (B.O.D.) and the adjusted
water consumption figure, and shall be determined and billed semi-
annually in accordance with current billing procedures and using
current reported analytical data.
Section Six. The surcharges herein established shall
become effective January 1, 1980.
