[Ord. 1-1997, 1/20/1997, Exh. A, § 2.1]
1.
No user shall contribute or cause to be contributed, directly or
indirectly, any pollutant or wastewater which will interfere with
the operation or performance of the POTW or cause pass through. These
general prohibitions apply to all such users of a POTW whether or
not the user is subject to National Categorical Pretreatment Standards
or any other national, state, or local pretreatment standards or requirements.
A user may not contribute the following substances to any POTW:
A.
Any liquids, solids or gases which by reason of their nature or quantity
are or may be sufficient either alone or by interaction with other
substances to cause fire or explosion to be injurious in any other
way to the POTW or to the operation of the POTW. At no time, shall
two successive readings on an explosion hazard meter, at the point
of discharge into the system (or at any point in the system), be more
than 5% nor any single reading over 10% of the lower explosive limit
(LEL) of the meter. Nor shall the discharge of a waste stream with
a closed cup flash point of less than 140° F. be allowed. Prohibited
materials include, but are not limited to, gasoline, kerosene, naphtha,
benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides,
chlorates, perchlorates, bromates, carbides, hydrides and sulfides
and any other substance which the City, the state or EPA has notified
the user is are a fire hazard or a hazard to the system.
B.
Solid or Viscous substances which may cause obstruction to the flow
in a sewer or other interference with the operation of the wastewater
treatment facilities such as, but not limited to: grease, petroleum
oil, nonbiodegradable cutting oil, or products of mineral oil origin
in amounts that will cause interference or pass through, garbage with
particles greater than 1/2 inch in any dimension, animal guts or tissues,
paunch manure, bones, hair, hides or fleshings, entrails, whole blood,
feathers, ashes, cinders, sand, spent lime, stone or marble dust,
metal, glass, straw, shavings, grass clippings, rags, spent grains,
spent hops, waste paper, wood, plastics, gas, tar, asphalt, residues,
residues from refining or processing of fuel, mud, or glass grinding
or polishing wastes.
C.
Any wastewater having a pH less than 6.0 or wastewater having any
other corrosive property capable of causing damage or hazard to structures,
equipment and/or personnel of the POTW.
D.
Any wastewater containing toxic pollutants in sufficient quantity,
either singly or by interaction with other pollutants, to injure or
interfere with any wastewater treatment process, constitute a hazard
to humans or animals, create a toxic effect in the receiving waters
of the POTW, or to exceed the limitation set forth in a categorical
pretreatment standard. A toxic pollutant shall include but not be
limited to any pollutant identified pursuant to § 307(a)
of the Act.
E.
Any pollutant which results in the production of toxic gases, vapors
or fumes within the POTW or collection system in a quantity that may
cause acute worker health and safety problems.
F.
Any noxious or malodorous liquid, gas or solid which, either singly
or by interaction with other wastes, is sufficient to create a public
nuisance or hazard to life or is sufficient to prevent entry into
the sewers for maintenance and repair.
G.
Any substance which may cause the POTW'S effluent or any other product
of the POTW such as residues, sludges or scums, to be unsuitable for
reclamation and reuse or to interfere with the reclamation process.
In no case shall a substance discharged to the POTW cause the POTW
to be in noncompliance with sludge use or disposal criteria, guidelines
or regulations developed under § 405 of the Act; any criteria,
guidelines or regulations affecting sludge use or disposal developed
pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic
Substances Control Act, or state criteria applicable to the sludge
management method being used.
H.
Any substance which will cause the POTW to violate its NPDES and/or
state disposal system permit or the receiving water quality standards.
I.
Any wastewater with objectionable color not removed in the treatment
process such as, but not limited to, dye wastes and vegetable tanning
solutions.
J.
Any wastewater having a temperature that will inhibit biological
activity in the POTW treatment plant resulting in interference, but
in no case wastewater with a temperature at the introduction into
the POTW which exceeds 40° C. (140° F.) unless the POTW treatment
plant is designed to accommodate such temperature.
K.
Any pollutant, including oxygen demanding pollutants (BOD, etc.),
released at a flow rate and/or pollutant concentration which a user
knows or has reason to know will cause interference to the POTW. In
no case shall a slug load have a flow rate or contain concentration
or qualities or pollutants that exceed for any time period longer
than 15 minutes more than five times the average twenty-four-hour
concentration, quantities or flow during normal operation.
L.
Any wastewater containing any radioactive wastes or isotopes of such
half life or concentration as may exceed limits established by the
Superintendent in compliance with applicable state or federal regulations.
M.
Any wastewater which causes a hazard to human life or creates a public
nuisance.
N.
The discharge of roof water, stormwater, surface drainage and building
foundation drainage to the sewer system is expressly prohibited.
O.
Any trucked or hauled wastes unless discharged at points designated
by the POTW.
P.
Wastewater causing, alone or in conjunction with other sources, the
POTW's effluent to fail a toxicity test.
2.
When the Superintendent determines that a user(s) is contributing
to the POTW any of the above enumerated substances in such amounts
as to interfere with the operation of the POTW, the Superintendent
shall:
[Ord. 1-1997, 1/20/1997, Exh. A, § 2.2]
Upon the promulgation of the Federal Categorical Pretreatment
Standards for a particular industrial subcategory, the federal standard,
if more stringent than limitations imposed under this Part for sources
in that subcategory, shall immediately supersede the limitations imposed
under this Part. The Superintendent shall notify all affected users
of the applicable reporting requirements under 40 CFR 403(12).
[Ord. 1-1997, 1/20/1997, Exh. A, § 2.3]
Where the Authority's wastewater treatment system achieves consistent
removal of pollutants limited by federal pretreatment standards, the
Authority may apply to the approval authority for modification of
specific limits in the federal pretreatment standards. "Consistent
removal" shall mean reduction in the amount of a pollutant or alteration
of the nature of the pollutant by the wastewater treatment system
to a less toxic or harmless state in the effluent which is achieved
by the system in 95% of the samples taken when measured according
to the procedures set forth in § 403(7)(c)(2) of (Title
40 of the Code of Federal Regulations, Part 403) — "General
Pretreatment Regulations for Existing and New Sources of Pollution"
promulgated pursuant to the Act. The City may then modify pollutant
discharge limits in the federal pretreatment standards if the requirements
contained in 40 CFR 403(7), are fulfilled and prior approval from
the approval authority is obtained.
[Ord. 1-1997, 1/20/1997, Exh. A, § 2.4]
[Ord. 1-1997, 1/20/1997, Exh. A, § 2.5]
State requirements and limitations on discharges shall apply
in any case where they are more stringent than federal requirements
and limitations or those in this Part.
[Ord. 1-1997, 1/20/1997, Exh. A, § 2.6]
The Authority, or an authorized representative thereof, reserves the right to establish by resolution and or permit more stringent limitations or requirements on discharges to the wastewater disposal system if deemed necessary to comply with the objectives presented in § 18-601 of this Part.
[Ord. 1-1997, 1/20/1997, Exh. A, § 2.7]
1.
No user shall ever increase the use of process water or, in any way,
attempt to dilute a discharge as a partial or complete substitute
for adequate treatment to achieve compliance with the limitations
contained in the Federal Categorical Pretreatment Standards, or in
any other pollutant-specific limitation developed by the City or state.
2.
The City reserves the right to require any industry having large
variations in rates of waste discharge to install suitable regulating
devices for equalizing waste flows.
3.
Industrial establishments discharging sewerage and industrial wastes
to the sewer system having an average five day biochemical oxygen
demand (BOD5) greater than 215 parts per million
(ppm), a suspended solids concentration greater than 250 ppm, a total
phosphorous (as P) content greater than 11 ppm or a total ammonia
nitrogen (as N) content greater than 20 ppm shall pay a strength of
waste surcharge, in addition to applicable volume charges, equal to
1/10 of 1% for each ppm by which the BOD5 exceeds
215 ppm, plus 1/10 of 1% for each ppm by which the suspended solids
exceeds 250 ppm, plus one and 1/10 of 1% for each ppm by which the
P concentration exceeds 11 ppm plus 7/10 of 1% for each ppm by which
the ammonia-nitrogen exceeds 20 ppm. Surcharges shall be applicable
to billing for sewer rentals under §§ 927.03 and 927.04
of the Streets, Utilities and Public Service Code. The strength of
sewerage and industrial waste to be used for establishing the amount
of surcharge shall be determined at least once annually either:
A.
By suitable sampling and analyses of the waste for a three-day period,
during which time the strength of waste discharged or production is
at a maximum.
B.
By relating production of waste strength at the time of sampling
to waste strength at maximum production if sampling is not performed
at the time of maximum production.
C.
From estimates made by the City.
D.
From known relationships of products produced to strengths of wastes
for those industries where such factors have been established.
4.
In establishing waste strengths for surcharge purposes, analysis
shall be made in accordance with procedures outlined in the latest
edition of "Standard Methods for the Examination of Water and Wastewater,"
published by the American Public Health Association. (City of Lebanon
Ordinance 82-1976, 77 & 5. Passed 6/30/77)
[Ord. 1-1997, 1/20/1997, Exh. A, § 2.8]
1.
Each user shall provide protection from accidental discharge of prohibited
materials or other substances regulated by this Part. Facilities to
prevent accidental discharge of prohibited materials shall be provided
and maintained at the owner or user's own cost and expense. Detailed
plans showing facilities and operating procedures to provide this
protection shall be submitted to the City for review, and shall be
approved by the City before construction of the facility. All existing
users shall complete such a plan by January 1, 1986. No user who commences
contribution to the POTW after the effective date of this Part shall
be permitted to introduce pollutants into the system until accident
discharge procedures have been approved by the City. Review and approval
of such plans and procedures shall not relieve the industrial user
from the responsibility to modify the user's facility as necessary
to meet the requirements of this Part. In the case of an accidental
discharge it is the responsibility of the user to immediately telephone
and notify the POTW of the incident. The notification shall include
location of discharge, type of waste, concentration and volume, and
corrective actions.
2.
Written Notice. Within five days following an accidental discharge;
the user shall submit to the Superintendent a detailed written report
describing the cause of the discharge and the measures to be taken
by the user to prevent similar future occurrences. Such notification
shall not relieve the user of any expense, loss, damage or other liability
which may be incurred as a result of damage to the POTW, fish kills,
or any other damage to person or property; nor shall such notification
relieve the user of any fines, civil penalties or other liability
which may be imposed by this Part or other applicable law.
3.
Notice to Employees. A notice shall be permanently posted on the
user's bulletin board or other prominent place advising employees
whom to call in the event of a dangerous discharge. Employers shall
insure that all employees who may cause or suffer such a dangerous
discharge to occur are advised of the emergency notification procedure.
