A.
All sewage and allowable industrial waste may be discharged
to the sewerage system except those which the Authority deems harmful
to the system or which are specifically prohibited by this chapter.
The Authority may from time to time amend these Rules and Regulations
to specifically prohibit certain discharges, and these Rules and Regulations
shall not be deemed to create any vested rights to any particular
discharge.
B.
No user shall discharge or cause to be discharged
any stormwater, surface water, groundwater, roof runoff, subsurface
drainage, cooling water, drainage from tile fields or unpolluted process
waters to any sanitary sewer.
C.
No user shall contribute or cause to be contributed,
directly or indirectly, any pollutant or wastewater which causes interference
or pass-through. These general prohibitions apply to all such users
of the sewerage system whether or not the user is subject to National
Categorical Pretreatment Standards or any other national, state, or
local pretreatment standards or pretreatment requirements.
D.
Except as otherwise provided in this chapter, no user
shall discharge or cause to be discharged to the sewerage system any
sewage, industrial waste, pollutant or other matter or substance:
(1)
Having a temperature which will inhibit biological
activity in the sewage treatment plant resulting in interference and/or
cause the temperature at the treatment plant to exceed 40° C.
(2)
Containing 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
or be injurious in any other way to the sewerage system or to the
operation of the sewage treatment plant, including, but not limited
to, waste streams with a closed-cup flash point of less than 140°
F. or 60° C. using the test methods specified in 40 CFR 261.21.
At no time shall two successive readings on any explosion hazard meter,
at the point of discharge into the system (or at any point in the

However, derivations from the above schedule may be authorized
by the Authority at its sole discretion, upon affirmative showing,
by the person requesting the same that such deviation will not be
harmful to the sewer system or the sewage treatment plant or cause
the plant effluent to violate its current NPDES discharge limitations.
For the purpose of this chapter, an allowable deviation may be granted
by the Authority, provided that the corresponding total loading allocated
for each objectionable substance does not exceed the maximum allowable
industrial loading limit. In no event shall any deviation allow the
total loading allocated to all industrial user for any pollutant to
exceed the maximum allowable industrial loading set forth in the most
recent local limits technical evaluation submitted by the Authority
and approved by EPA as part of the Authority's pretreatment program.
Deviations granted by the Authority shall be incorporated in the industrial
user's discharge permit. In no event shall a deviation allow a discharge
to occur that is below the federal pH standard of 5.0 S.U.

E.
If any waters or wastes are discharged, or proposed
to be discharged to the sewerage system, which waters or wastes contain
the substances or possess the characteristics enumerated and prohibited
in this chapter or which in the judgment of the Executive Director
may have a deleterious effect upon the sewerage system or receiving
waters, the Executive Director may, upon giving official notice to
the discharger:
(1)
Reject the waste.
(2)
Require pretreatment to reduce characteristics to
daily maximum allowable concentrations permitted by this chapter or
any other applicable rules or law.
(3)
Require control over the quantities and rates of discharge.
(4)
Require immediate discontinuance of the waste discharge
until such time as it meets the requirements of this chapter.
F.
Grease, oil, and sand interceptors or traps shall
be provided where, in the opinion of the approving authority, they
are necessary for the proper handling of liquid wastes containing
grease in excessive amounts or any flammable wastes, sand, or other
harmful ingredients. All interceptors shall be of a type and capacity
acceptable to the Executive Director and shall be located as to be
readily and easily accessible for cleaning and inspection.
G.
The use of mechanical garbage grinders producing a
finely divided mass, properly divided mass, properly flushed with
an ample amount of water, shall be permitted upon the condition that
no such mechanical garbage grinder to serve premises used for commercial
purposes shall be installed until permission for such installation
shall have been obtained from the Executive Director.
H.
Where pretreatment or flow-equalizing facilities are
provided for any waters or wastes, they shall be maintained continuously
in satisfactory and effective operation by the owner at his expense
and shall be accessible to the Authority for inspection and testing.
A.
Upon the promulgation of the categorical pretreatment
standards for a particular industrial subcategory, the general standard,
if more stringent than limitations imposed under this chapter for
sources in that subcategory, shall immediately supersede the limitations
imposed under this chapter. The Authority shall notify all affected
users of the applicable reporting requirements under 40 CFR 403.12.
The categorical standards found at 40 CFR Chapter I, Subchapter N,
Parts 405-471, are incorporated herein by reference.
B.
Modification of federal categorical pretreatment standards.
Where the Authority's sewage treatment plant achieves consistent removal
of pollutants limited by federal categorical standards, the Authority
may apply to the regulatory authority for modification of specific
limits in the federal categorical standards.
C.
"Consistent removal" shall mean the average of the lowest 50% of the removal measured according to § 60-4D. All sample data obtained for the measured pollutant during the time period prescribed in § 60-4D must be reported and used in computing consistent removal. If a substance is measurable in the influent but not in the effluent, the effluent level may be assumed to be the limit of measurement, and those data may be used by the Authority. If the substance is not measurable in the influent, the data may not be used. Where the number of samples with concentration equal to or above the limit of measurement is between eight and 12, the average of the lowest six removals shall be used. If there are less than eight samples with concentration equal to or above the limit of measurement, the Authority may approve alternate means for demonstrating consistent removal. The term “measurement” refers to the ability of the analytical method or protocol to quantify as well as identify the presence of the substance in question.
D.
"Consistent
removal data" shall mean influent and effluent operational data demonstrating
consistent removal or other information, as provided for in the definition
of “consistent removal” above, which demonstrates consistent
removal of the pollutants for which discharge limit revisions are
proposed. These data shall meet the following requirements:
(1)
Representative
data, seasonal. The data shall be representative of yearly and seasonal
conditions to which the POTW is subjected for each pollutant for which
a discharge limit revision is proposed.
(2)
Representative
data; quality and quantity. The data shall be representative of the
quality and quantity of normal effluent and influent flow if such
data can be obtained. If such data are unattainable, alternate data
or information may be presented for approval to demonstrate consistent
removal.
State requirements and limitations on discharge
shall apply in any case where they are more stringent than federal
requirements and limitations or those in this chapter.
A.
The Authority has adopted the Chapter 249, Sewers
(adopted September 15, 2007, and amended 11-27-2012), of the Code
of Ordinances of the City of Lancaster pertaining to the sewer lines
in Manheim Township that contribute flow to the City's publicly owned
treatment works.
[Amended 1-24-2013 by Res. No. 13-01-003]
B.
Chapter 249, Sewers, of the Code of Ordinances of
the City of Lancaster and the LASA Rules and Regulations shall be
complementary, and where there is a contradiction between documents,
the more strict requirements will be enforced.
C.
The Authority agrees to cooperate with the City and
Manheim Township in the enforcement and/or prosecution of violators
of LASA's Rules and Regulations, with respect to violations of the
City regulations originating with Manheim Township and the contributing
sections in accordance with the terms of the City's Enforcement Response
Plan. The City will not be obligated to prosecute persons who have
violated regulations regarding conveyance or matters other than treatment.
The Authority reserves the right to establish by resolution more stringent limitations or requirements on discharges to the sewerage system if deemed necessary to comply with the objectives presented in § 60-1 of this chapter. Nothing in these Rules and Regulations shall be deemed to create any vested right in any user to a particular level, amount, concentration, characteristic or type of discharge.
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 Authority or state.
A.
Each user
shall provide protection from accidental discharge of prohibited materials
or other substances regulated by this Authority, and from slugs. Facilities
to prevent slugs or accidental discharge of prohibited materials shall
be provided and maintained at the owner's or user's own cost and expense.
Detailed plans showing facilities and operating procedures to provide
this protection shall be submitted to the Authority for review and
shall be approved by the Authority before construction of the facility.
No user who commences contribution to the sewerage system after the
effective date of this chapter shall be permitted to introduce pollutants
into the sewerage system until slug and accidental discharge procedures
have been approved by the Authority. Review and approval of such plans
and operating procedures shall not relieve the user from the responsibility
to modify the user's facility as necessary to meet the requirements
of this chapter. In the case of an accidental discharge or slug discharge,
it is the responsibility of the user to immediately telephone and
notify the Authority of the incident. The notification shall include
location of discharge, type of waste, concentration and volume, and
corrective actions.
B.
Any user
required to develop and implement an accidental spill prevention and/or
slug control plan shall submit a plan which addresses, at a minimum,
the following:
(1)
Description
of discharge practices, including nonroutine batch discharges;
(2)
Description
of stored chemicals;
(3)
Procedures for immediately notifying the Authority of any accidental or slug discharges, including any discharge that would violate a prohibition under § 60-3, with procedures for follow-up written notification within five days;
(4)
If required
by the Authority procedures to prevent adverse impact from accidental
spills, including inspection and maintenance of storage areas, handling
and transfer of materials, loading and unloading operations, control
of plant site runoff, worker training, building of containment structures
or equipment, measures for containing toxic organic chemicals (including
solvents), and/or measures and equipment for emergency response.
Within five days following an accidental or
slug discharge, the user shall submit to the Executive Director a
detailed written report describing the cause of the accidental or
slug 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 sewerage system, 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 chapter or other applicable law.
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 or unauthorized discharge.
Employers shall ensure that all employees who may suffer such a dangerous
discharge to occur are advised of the emergency notification procedure.
Filter backwash lines shall be discharged to
the sewerage system as follows:
A.
Sand filter backwash may be discharged to the sewerage
system.
B.
Diatomaceous earth filter backwash shall be connected
to the sewerage system through settling tanks with three months' storage
capacity of spent diatomaceous earth, which tanks shall be readily
accessible for removing solid waste for disposal.
A.
The industrial wastes discharged by tank trucks into the sewerage system shall not contain industrial waste, chemicals, or other matter, with or without pretreatment that does not conform to the requirements of this Chapter 60, Industrial Waste, of these Rules and Regulations.
B.
Any industrial waste to be discharged from tank trucks
shall be disposed at the location designated at the sewage treatment
plant at the time or times and at the rate or rates of discharge fixed
by the Authority.
Users shall design, construct, operate and maintain
wastewater pretreatment facilities whenever necessary to reduce or
modify the user's wastewater to achieve compliance with this chapter,
national pretreatment standards, pretreatment requirements, and conditions
or limitations contained in the user's industrial waste discharge
permit, or any sludge limitation imposed by federal, state or local
authorities. The review or approval of pretreatment facility plans,
specifications and operating procedures by the Authority or its consulting
engineer shall not excuse or mitigate any violations by the user of
this chapter or any federal, state or local requirements.
