The following words and terms, when used in this article, shall
have the following meanings, unless the context clearly indicates
otherwise:
ACT
Federal Water Pollution Control Act, also know as the "Clean
Water Act," as amended 33 U.S.C. § 1251 et seq.
BOD (BIOCHEMICAL OXYGEN DEMAND)
The quantity of oxygen utilized in the biochemical oxidation
of organic matter under standard laboratory procedure in five days
at 20° C., expressed in terms of weight and concentration [milligrams

Schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to implement the general and specific prohibitions listed in §
364-28 and 40 CFR 403.5(a)(1) and (b). BMPs also include treatment requirements, operating procedures, and practices to control plant site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage.
CFR
Code of Federal Regulations.
COMMERCIAL WASTES
The wastes generated from a commercial operation as distinct
from domestic and industrial sewage.
COMPOSITE SAMPLE
A combination of individual samples obtained at regular intervals
over the period of discharge. Whenever practical, composite samples
shall be proportionate to flow rate so as to be representative of
the discharge during the period of sampling. When an industrial waste
discharge is collected over a period of time and discharged as a daily
basis or less frequent batch, a single sample from the batch shall
be considered a composite sample for purposed of this article.
DAILY DISCHARGE
The discharge of a pollutant measured during a calendar day
or any twenty-four-hour period that reasonably represents the calendar
day for purposes of sampling. For pollutants with limitations expressed
in units of mass, the "daily discharge" is calculated as the total
mass of the pollutant discharged over the day. For pollutants expressed
in other units of measurement (i.e., mg/l), except for pH, the "daily
discharge" is calculated as the arithmetic average measurement of
the pollutant derived from all measurements taken that day or by the
measurement of a composite sample taken that day.
DOMESTIC SEWAGE
The water-borne waste derived from ordinary living processes.
GARBAGE
Solid waste from the preparation, cooking and dispensing
of food, and from the handling, storage and sale of produce.
GARBAGE GRINDERS
A mechanical device that shreds or grinds food into small
particles for the purpose of sewage disposal.
GENERAL MANAGER
The General Manager of the City of York Wastewater Treatment
Plant or his duly authorized representatives or designees.
GRAB SAMPLE
An individual sample that is taken from a wastestream without
regard to the flow in the wastestream and over a period of time not
to exceed 15 minutes.
GROUND GARBAGE
The residue from the preparation, cooking and dispensing
of food that has been shredded to such degree that all particles shall
be carried freely in suspension under the normal flow conditions prevailing
in the sewer conduit to which they are contributory and those prevailing
in public sewers with no particle greater than 1/2 inch in any dimension.
INDUSTRIAL WASTES
The wastes from industrial processes as distinct from domestic
and commercial sewage.
INTERCEPTOR
A device designed and installed so as to separate and retain
deleterious, hazardous, or undesirable matter from normal wastes,
while allowing normal sewage or wastes to discharge into the drainage
system by gravity.
INTERFERENCE
A discharge which, alone or in conjunction with a discharge
or discharges from other sources, both:
A.
Inhibits or disrupts the POTW, its treatment processes or operations,
or its sludge processes, use or disposal; and
B.
Therefore is a cause of a violation of any requirement of the
POTW's NPDES permit (including an increase in the magnitude or duration
of a violation) or of the prevention of sewage sludge use or disposal
in compliance with the following statutory provisions and regulations
or permits issued thereunder (or more stringent state or local regulations):
Section 405 of the Clean Water Act, the Solid Waste Disposal Act (SWDA)
(including Title II, more commonly referred to as the "Resource Conservation
and Recovery Act" (RCRA), and including state regulations contained
in any state sludge management plan prepared pursuant to Subtitle
D of the SWDA), the Clean Air Act, the Toxic Substances Control Act,
and the Marine Protection, Research and Sanctuaries Act [40 CFR 403.3(k)].
LOCAL LIMIT
Specific discharge limits developed and enforced by the City
of York upon industrial or commercial facilities to implement the
general and specific discharge prohibitions listed in 40 CFR 403.5(a)(1)
and (b). Local limits are found at Section 931.02(b)(2), Section 931.02(b)(6),
and Section 931.02(b)(13).

MONTHLY AVERAGE
The sum of all daily discharges measured during a calendar
month divided by the number of daily discharges measured during that
month.
MONTHLY AVERAGE LIMIT
The highest allowable average of daily discharges over a
calendar month, calculated as the sum of all daily discharges measured
during a calendar month divided by the number of daily discharges
measured during that month.
NEW SOURCE
Any building, structure, facility, or installation from which
there is or may be a discharge of pollutants, the construction of
which commenced after the publication of proposed pretreatment standards
under Section 307(c) of the Clean Water Act if such standards are
thereafter promulgated in accordance with that section (provided that
certain conditions dealing with the construction and sitting of that
source vis-a-vis other sources are met) [40 CFR 403.3(m)(1)].
PASS-THROUGH
A discharge which exits the POTW into waters of the United
States in quantities or concentrations which, alone or in conjunction
with a discharge or discharges from other sources, is a cause of a
violation of any requirement of the POTW's NPDES permit (including
an increase in the magnitude or duration of a violation) [40 CFR 403.3(p)].
PERSON
Any individual, partnership, firm, company, corporation,
association, joint stock company, trust, estate, governmental entity,

pH, temperature, TSS, turbidity, color, BOD, COD, toxicity, or odor).
PRETREATMENT
The reduction of the amount of pollutants, the elimination
of pollutants, or the alteration of the nature of pollutant properties
in wastewater prior to or in lieu of discharging or otherwise introducing
such pollutants into a POTW. The reduction or alteration may be obtained
by physical, chemical or biological processes, process changes or
by other means, except as prohibited by 40 CFR 403.6(d). Appropriate
pretreatment technology includes control equipment, such as equalization
tanks or facilities, for protection against surges or slug loadings
that might interfere with or otherwise be incompatible with the POTW.
However, where wastewater from a regulated process is mixed in an
equalization facility with unregulated wastewater or with wastewater
from another regulated process, the effluent from the equalization
facility must meet an adjusted pretreatment limit calculated in accordance
with 40 CFR 403.6(e).
PRETREATMENT REQUIREMENTS
Any substantive or procedural requirement related to pretreatment,
other than a national pretreatment standard, imposed on an industrial
user.
PUBLICLY OWNED TREATMENT WORKS or POTW
A treatment works as defined by Section 212 of the Act, which
is owned by a state or municipality (as defined by Section 502(4)
of the Act);this definition includes any devices and systems used
in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes sewers,
pipes and other conveyances only if they convey wastewater to a POTW
treatment plant. The term also means the municipality as defined in
Section 502(4) of the Act, which has jurisdiction over the indirect
discharges to and the discharges from such a treatment work [40 CFR
403.3(q)].

A.
An industrial user subject to categorical pretreatment standards;
or
B.
An industrial user that:
(1)
Discharges an average of 25,000 gallons per day (gpd) or more
of process wastewater to the POTW (excluding sanitary, noncontact
cooling and boiler blowdown wastewater);
(2)
Contributes a process wastestream which makes up 5% or more
of the average dry weather hydraulic or organic capacity of the POTW
treatment plant; or
(3)
Is designated as such by the City of York on the basis that
it has a reasonable potential for adversely affecting the POTW's operation
or for violating any pretreatment standard or requirement.
C.
The General Manager may determine that an industrial user subject
to categorical pretreatment standards is a nonsignificant categorical
industrial user rather than a significant industrial user on a finding
that the industrial user never discharges more than 100 gallons per
day (gpd) of total categorical wastewater (excluding sanitary, noncontact
cooling and boiler blowdown wastewater, unless specifically included
in the pretreatment standard) and the following conditions are met:
(1)
The industrial user, prior to the General Manager's finding,
has consistently complied with all applicable categorical pretreatment
standards and requirements;
(2)
The industrial user annually submits the certification statement
required in 40 CFR 403.12(q), together with any additional information
necessary to support the certification statement; and
(3)
The industrial user never discharges any untreated concentrated
wastewater.
D.
Upon a finding that a user meeting the criteria in Subsection
B of this definition has no reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, the General Manager may at any time, on its own initiative or in response to a petition received from an industrial user, and in accordance with procedures in federal pretreatment requirements of 40 CFR Chapter I, Subchapter N, determine that such user should not be considered a significant industrial user.
SLUG or SLUG DISCHARGE
Any discharge at a flow rate or concentration, which could cause a violation of the prohibited discharge standards in §
364-28 of this article. A slug discharge is any discharge of a nonroutine, episodic nature, including, but not limited to, an accidental spill or a noncustomary batch discharge, which has a reasonable potential to cause interference or pass-through, or in any other way violate the POTW's regulations, local limits or permit conditions.

The General Manager and other duly authorized employees of the
City of York bearing proper credentials and identification shall be
permitted to enter upon all properties at reasonable times to carry
out all inspection, surveillance, observation, measurement, monitoring
procedures, sampling and testing necessary to determine, independent
of information supplied by industrial users, compliance or noncompliance
with applicable pretreatment standards and requirements and ordinance
requirements by industrial users. The General Manager shall have the
right to enter any premises of any industrial user in which a discharge
source or treatment system is located, or in which records are required
to be kept under 40 CFR 403.12(o), to ensure compliance with pretreatment
standards or requirements, any wastewater discharge permit, the requirements
of this chapter, or an order issued hereunder. Users shall allow the
General Manager ready access to all parts of the premises for the
purposes of inspection, sampling, records examination and copying,
and the performance of any additional duties. The Authority of the
General Manager shall be at least as extensive as the authority provided
under Section 308 of the Clean Water Act.
A. Where a user has security measures in force that require proper identification
and clearance before entry into its premises, the user shall make
necessary arrangements with its security personnel so that, upon presentation
of suitable identification, the General Manager shall be permitted
to enter without delay for the purposes of performing specific responsibilities.
B. The General Manager shall have the right to set up on the user's
property, or require installation of, such devices as are necessary
to conduct sampling and/or metering of the user's operations.
C. Any temporary or permanent obstruction to safe and easy access to
the facility to be inspected and/or sampled shall be promptly removed
by the user at the written or verbal request of the General Manager
and shall not be replaced. The costs of clearing such access shall
be the responsibility of the user.
D. If the General Manager has been refused access to a building, structure,
or property, or any part thereof, and is able to demonstrate probable
cause to believe that there may be a violation of this article, or
that there is a need to inspect and/or sample as part of a routine
inspection and sampling program of the City of York designed to verify
compliance with this article or any permit or order issued hereunder,
or to protect the overall public health, safety and welfare of the
community, the General Manager may seek issuance of a search warrant
from the appropriate court.
All persons storing or using flammable or hazardous materials
or discharging matter likely to obstruct any part of the sewage works
or injure same or cause a nuisance, shall not connect to any sanitary
sewer except through interceptors, catch basins or screens as may
be prescribed by the City of York. Nothing in this section shall be
interpreted as superseding the limitations and prohibitions on the
discharge of particular wastes or waste characteristics as set forth
elsewhere in this article.
The City of York shall annually provide public notification
in a newspaper of general circulation that provides meaningful public
notice within the jurisdiction(s) served by the POTW of industrial
users which, at any time during the previous 12 months, were in significant
noncompliance with applicable pretreatment standards and requirements.
For the purposes of this provision, a significant industrial user
(or any industrial user that violates Subsection C, D or H of this
section) is in significant noncompliance if its violation meets one
or more of the following criteria:
A. Chronic violations of wastewater discharge limits, defined here as
those in which 66% or more of all of the measurements taken for the
same pollutant parameter during a six-month period exceed (by any
magnitude) a numeric pretreatment standard or requirement, including
instantaneous limits, as defined by 40 CFR 403.3(I).
B. Technical review criteria (TRC) violations, defined here as those
in which 33% or more of all of the measurements taken for the same
pollutant parameter during a six-month period equal or exceed the
product of the numeric pretreatment standard or requirement including
instantaneous limits, as defined by 40 CFR 403 multiplied by the applicable
TRC. There are two groups of TRC:
(1) Group I for BOD, TSS, fats, oil, and grease: TRC 1.4.
(2) Group II for all other pollutants except pH: TRC 1.2.
C. Any other violation of a pretreatment standard or requirement as
defined by 40 CFR 403.3(1) (daily maximum, long-term average, instantaneous
limit, or narrative standard) that the POTW determines has caused,
alone or in combination with other discharges, interference or pass-through
(including endangering the health of POTW personnel or the general
public).
D. Any discharge of a pollutant that has caused imminent endangerment
to human health, welfare or to the environment or has resulted in
the POTWs exercise of its emergency authority to halt or prevent such
a discharge.
E. Failure to meet, within 90 days after the schedule date, a compliance
schedule milestone contained in a local control mechanism or enforcement
order for starting construction, completing construction, or attaining
final compliance.
F. Failure to provide, within 30 days after the due date, required reports
such as baseline monitoring reports, ninety-day compliance reports,
periodic self-monitoring reports, reports on best management practices,
and reports on compliance with compliance schedules.
G. Failure to accurately report noncompliance.
H. Any other violation or group of violations, which may include a violation
of best management practices, which the POTW determines will adversely
affect the operation or implementation of the local pretreatment program.
Information and data on a user obtained from reports, surveys,
wastewater discharge permit applications, individual wastewater discharge
permits, and monitoring programs, and from the General Manager's inspection
and sampling activities, shall be available to the public without
restriction, unless the user specifically requests, and is able to
demonstrate to the satisfaction of the General Manager, that the release
of such information would divulge information, processes, or methods
of production entitled to protection as trade secrets under applicable
state and federal law. Any such request must be asserted at the time
of submission of the information or data if the industrial user stamps
"Confidential Business Information" over all parts for which protection
is sought. When requested and demonstrated by the user furnishing
a report that such information should be held confidential, the portions
of a report which might disclose trade secrets or secret processes
shall not be made available for inspection by the public, but shall
be made available immediately upon request to governmental agencies
for uses related to the NPDES program or pretreatment program, and
in enforcement proceedings involving the person furnishing the report.
Wastewater constituents and characteristics and other effluent data,
as defined at 40 CFR 2.302 shall not be recognized as confidential
information and shall be available to the public without restriction.
In compliance with the Commonwealth of Pennsylvania's Right-To-Know
Law, requests for City of York records shall be submitted to the City
of York's Open Records Officer.
Except as otherwise provided herein, the General Manager shall
administer, implement, and enforce the provisions of this article.
Any powers granted to or duties imposed upon the General Manager may
be delegated to a duly authorized City of York employee.
Should any section or provision of this article be declared
by the courts to be unconstitutional or invalid such decision shall
not affect the validity of this article as a whole or any part thereof
other than the part so declared to be unconstitutional or invalid.
