In addition to any other tax, fee, charge or sewer rent imposed
or levied for the construction, maintenance, operation, repair, improvement
and management of the Village of Webster sewerage system or any public
sewer tributary thereto, the owner or lessee of any parcel of real
property connected with such system or sewer, including but not limited
to real property connected to such system by means of a private sewer
or drain discharging into the Village of Webster sewer systems or
any public sewer tributary thereto, shall pay a sewer surcharge for
the use of the Village of Webster sewerage system or tributary public
sewer for discharging:
A.
Any sewage, industrial wastes or other wastes accepted for admission
thereto in which the characteristics resulting from the pollutants
contained therein exceed the maximum values as stated in the definition
of normal sewage in this Part 2 and the rules and regulations.
B.
Any waters, such as stormwater connections from any building or yard, any drain from catch basins, lakes, swamps or ponds or swimming pool drains, cooling waters or any other source of waters as defined in § 113-14 or 113-19, except with permission of the Superintendent evidenced by a properly issued permit.
C.
Any groundwaters which enter the Village of Webster sewerage system
by infiltration of local or private sewage collection systems.
The formula for the sewer surcharge shall be computed by the
Superintendent. The amount of the surcharge shall be the product of
the surcharge factor and the established sewerage system charge for
operation and maintenance. The general form for the determination
shall be as follows:
|
SF
|
=
|
a(BOD - 300)
300
|
+
|
b(SS - 300)
300
|
+
|
c(CLD - 25)
25
|
+
|
d(P - 30)
30
|
|
Where:
| |||
|
SF
|
=
|
Surcharge factor.
| |
|
BOD
|
=
|
Milligrams per liter of biochemical oxygen demand, as defined in § 113-14.
| |
|
SS
|
=
|
Milligrams per liter of suspended solids, as defined in § 113-14.
| |
|
CLD
|
=
|
Milligrams per liter of chlorine demand, as defined in § 113-14.
| |
|
P
|
=
|
Milligrams per liter of phosphorus, as defined in § 113-14.
| |
|
a
|
=
|
Proportion of operation and maintenance cost to treat a pound
of biochemical oxygen demand (BOD).
| |
|
b
|
=
|
Proportion of operation and maintenance cost to treat a pound
of suspended solids (SS).
| |
|
c
|
=
|
Proportion of operation and maintenance cost to treat a pound
of chlorine demand (CLD).
| |
|
d
|
=
|
Proportion of operation and maintenance cost to treat a pound
of phosphorus (P).
| |
|
NOTES:
| |
|
1.
|
Items a, b, c and d are decimal portions of the total operation
and maintenance cost for the sewerage system. The values shall be
determined by the Administrator on a yearly basis from data accumulated
during each preceding year from the actual operation and maintenance
costs.
|
|
2.
|
If any of the values for BOD, SS, CLD or P as determined by laboratory analysis are less than the respective normal values stated in § 113-14, the factor for the pollutant shall be eliminated from the formula.
|
|
Example 1. Treatment charge based on volume.
| ||
|
An industry discharges into the public sewer system wastes which
have been found to contain the following:
| ||
|
BOD: 630 milligrams per liter; normal value 300 milligrams per
liter
| ||
|
SS: 280 milligrams per liter; normal value 300 milligrams per
liter
| ||
|
CLD: 50 milligrams per liter; normal value 25 milligrams per
liter
| ||
|
P: 45 milligrams per liter; normal value 30 milligrams per liter
| ||
|
Monthly volume of discharge = 100,000 gallons
| ||
|
Normal operation and maintenance sewer charge = $0.70/1,000
gallons
| ||
|
Values for a, b, c and d are, respectively: 0.53, 0.35, 0.08
and 0.04
| ||
|
SF
|
=
|
0.53(630 - 300)
300
|
+
|
0.08(50-25)
25
|
+
|
0.04 (45 - 30)
30
|
|
SF
|
=
|
0.53 (1.1) + 0.08 (1.0) + 0.04 (0.5)
|
|
SF
|
=
|
0.68
|
|
NOTES:
| ||
|
1.
|
The factor for SS is dropped because SS is less than 300 milligrams
per liter.
| |
|
2.
|
Surcharge factors are rounded off to two decimal places.
| |
|
Normal sanitary sewer operation and maintenance charge =
| ||
|
100,000 x 0.70
1,000 gallons
| ||
|
= $70.00 per month maintenance charge
| ||
|
Surcharge = (0.68) ($70.00) = $47.60
| ||
|
Total sewerage treatment charge = $70.00 + $47.60 = $117.60
per month
| ||
|
This example illustrates sewer use by large commercial or industrial
establishments and not average residential users with normal sewage.
|
|
Example 2. Treatment charge based on unit rates.
| |||
|
A commercial establishment discharging wastes into the public
sewer system is rated at 20 equivalent units. (One unit is equivalent
to a dwelling unit or lot or 60,000 gallons per year of water consumption.)
The unit charge is $45 per unit per year. The establishment discharges
wastes into the public sewer system which has been found to contain
the following concentrations of pollutants:
| |||
|
BOD
|
=
|
450 MG/L
| |
|
SS
|
=
|
200 MG/L
| |
|
CLD
|
=
|
15 MG/L
| |
|
P
|
=
|
60 mg/l
| |
|
Values for a, b, c and d are, respectively: 0.3, 0.3, 0.1 and
0.2
| |||
|
Normal sanitary sewer charge = (20 units x $45.00)) + $1.00;
fixed district parcel charge = $901.00 per year.
| |||
|
SF
|
=
|
0.3 (450 - 300) + 0.2 (60 - 30) 300 30
| |
|
NOTE: The factors for SS and CLD are dropped because values
are below normal limits.
| ||
|
SF = (0.3)(0.5) + (0.2)(1) = 0.35
| ||
|
Portion of unit charge which is cost of treatment =
| ||
|
$27.55
$45.00
|
= $0.61
| |
|
Surcharge = (0.35) ($0.61) ($901.00) = $192.36
| ||
|
Total sewer charge = $901.00 + $192.36 = $1,093.36
| ||
|
Both of these examples illustrate sewer use by large commercial
or industrial establishments and not average residential users with
normal sewage.
| ||
|
The sewer surcharge for unpolluted water discharge into the
Village of Webster sewerage system or tributary public sewer shall
be:
| ||
|
A.
|
In the case of a volume charge as in Example 1, double the normal
sanitary sewer treatment charge based on the volume of metered water;
and/or
| |
|
B
|
In the case of unit charge, the product of the following:
| |
|
(1)
|
Unit charge portion due to treatment cost.
| |
|
(2)
|
Pollutant surcharge factor, if any, as computed by formula.
| |
|
(3)
|
Normal sewer charge (see Example 2).
| |
|
NOTE: When excessive volumes of water (stormwater, surface water,
groundwater, etc.) enter the Village of Webster sewerage system directly
or by inflow or infiltration of the local sewage collection systems,
the Village shall take the following actions:
| ||
|
(1)
|
Notice shall be given to the property owner or local governmental
unit responsible for the sewage collection system contributing excessive
volumes of water into the Village of Webster sewerage system.
| |
|
(2)
|
Within 30 days after notification to the property owner or local
governmental unit, an informal timetable for the elimination and/or
control of the excessive water infiltration shall be filed with the
Village.
| |
|
(3)
|
A property owner or local governmental unit failing to provide
said timetable or not substantially complying with the scheduled abatement
of excessive inflow or infiltration to the timetable filed with Village
shall be surcharged for the excessive water.
| |
|
(4)
|
The surcharge shall be based in proportion to the determined
excess volume of water entering the Village of Webster sewerage system.
| |
The surcharge for permittees with a permanent connection to the Village of Webster sewerage system or a tributary public sewer shall be surcharged on the Village charges. Other users requiring a permit, as provided in Article XI, will be charged administrative cost and the surcharge in the fee required to obtain the permit from the Superintendent.
The Superintendent shall compute all surcharges using the formula in § 113-53 and factors adopted by the Village of Webster. The data used to compute the surcharge will be supplied by inspections, by the application for permit and/or any method determined by the Village of Webster after the Superintendent's review of the facts which, in the Superintendent's belief, give, as nearly as possible, accurate volume determination and/or the average pollutant concentration. All surcharges shall be based on the analysis of wastes from any plant or premises in relation to the total volume of wastes and waters, except in the case of special contract in accordance with § 113-57. The data, once established as the average pollutant concentration, shall be used until inspection or other reliable proof justifies a change in the average pollutant concentration.
Adjustment of an account for which payment has been received
that results in an overpayment shall be made. Said overpayment shall
be a credit to the account.
A.
The Village of Webster may negotiate special contracts for handling
sewage, industrial wastes or other wastes. One of the following conditions
must exist before a special contract can be negotiated:
(1)
If an industry or establishment has a New York State Department of
Environmental Conservation approved permit to discharge in a classified
watercourse.
(2)
If the total volume or contribution of waste to the public sewer
system is greater than 1,000,000 gallons per day or 5% of the average
design capacity of water pollution control facility receiving the
waste.
(3)
If the contributor is a local, state or federal governmental agency.
(4)
If scavenger waste or other waste is so unusual that it is not covered
by the scavenger waste or surcharge provisions of this Part 2.
B.
The terms and conditions of special contracts shall not be at variance
with Federal Categorical Pretreatment Standards.
