Fats, oils, and grease, (FOG) and sand interceptors shall be
provided when, in the opinion of the Director or POTW, they are necessary
for the proper handling of liquid wastes containing fats, oils, or
grease discharges in which the concentration in a grab sample exceeds
the 100 mg/l limit, or any flammable wastes, sand, or other harmful
ingredients; except that such interceptors shall not be required for
single-family or multiple-family dwelling units. All interceptors
shall be of a type and capacity approved by the Director or POTW and
shall be located as to be readily and easily accessible for cleaning
and inspection. Grease and oil interceptors shall be constructed of
impervious materials capable of withstanding abrupt and extreme changes
in temperature. They shall be of substantial construction, watertight
and equipped with easily removable covers which when bolted into place
shall be gastight and watertight. When installed, all fats, oils,
and grease, and sand interceptors shall be maintained by the owner,
at his expense, in continuously efficient operation at all times.
A user may petition the Director or POTW for an exemption from having
to install a fats, oils, and grease (FOG) interceptor in accordance
with provisions specified in the YCUA FOG mitigation program policy,
as amended from time to time. Upon approval by the YCUA, if the Township
has a fats, oils, and grease ordinance/policy the Township can implement
said ordinance/policy in lieu of this section and the YCUA fats, oils,
and grease mitigation program policy.
Upon the promulgation of the National Categorical Pretreatment
Standards, alternative discharge limits, or other federal or state
limitations, for a particular industrial subcategory, the pretreatment
standard, if more stringent than limitations imposed under this Part
4 for sources in that subcategory, shall immediately supersede the
limitations imposed under this Part 4 and shall be considered part
of this Part 4. The PTUD shall notify all affected users of the applicable
reporting requirements.
Sampling and analysis shall be performed in accordance with
the techniques prescribed in 40 CFR Part 136 (March 26, 2007). Where
40 CFR Part 136 (March 26, 2007) does not contain sampling or analytical
techniques for the pollutant in question, or where the EPA determines
that the Part 136 (March 26, 2007) sampling and analytical techniques
are inappropriate for the pollutant in question, sampling and analysis
shall be performed by using validated analytical methods or any other
applicable sampling and analytical procedures, including procedures
suggested by PTUD, POTW, or other parties, approved by the EPA.
With respect to compatible pollutants only, no statement contained
in this Part 4 shall be construed as preventing any agreement between
the Director or POTW and any user whereby an industrial waste of unusual
strength or character may be accepted, subject to payment therefor
by the user, provided such agreement shall not violate EPA guidelines
or NPDES requirements and provided user charges and surcharges as
provided in this Part 4 are agreed to in the agreement.
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 National Categorical Pretreatment Standards, alternative
discharge limits, or in any other pollutant-specific limitation developed
by the PTUD, POTW, or the state.
To determine the sewage flow from any establishment, the PTUD
or POTW may use one of the following methods:
A. The amount of water supplied to the premises by the public water
system as shown upon the water meter if the premises are metered.
B. If the premises are supplied with river water or water from private
wells, the amount of water supplied from such sources may be metered
at the source or metered at its point of discharge prior to entry
into the public sewer.
C. If such premises are used for an industrial or commercial purpose
of such a nature that the water supplied to the premises cannot be
entirely discharged into the sewer system, the estimate of the amount
of sewage discharged into the sewer system made by the utilities authority
from the water, gas or electric supply, or metered at its point of
discharge prior to entry into the public sewer.
D. The volume of sewage discharged into the sewer system as determined
by measurements and samples taken at a manhole installed by the owner
of the property served by the sewer system at his own expense in accordance
with the terms and conditions of the permit issued by the PTUD or
POTW pursuant to this Part 4.
E. A figure determined by the PTUD or POTW by any combination of the
foregoing or by any other equitable method.
Waste from industrial sewage disposal systems shall be disposed of at the wastewater treatment plant or at any other refuse or disposal site approved by the Director. No waters or wastes described in §
36-80 shall be disposed of at the YCUA wastewater treatment plant.
If the results of any sampling performed by the user indicates
that any violation of this Part 4, a permit, an order issued under
this Part 4, the IPP, the Act or State Act has occurred, the user
shall notify the PTUD or POTW within 24 hours of becoming aware of
the violation and shall repeat the sampling and pollutant analysis
and shall submit, in writing, the results of this repeat analysis
within 30 days after becoming aware of the violation. A written follow
up report shall be filed by the user with the PTUD, POTW, and YCUA
within five days of a user becoming aware of the violation. The report
shall specify the following:
A. A description of the violation, the cause thereof, and the violation's
impact on the user's compliance status.
B. Duration of the violation, including exact dates and times of the
violation, and if not corrected, the anticipated time the violation
is expected to continue.
C. All steps taken or intended to be taken to reduce, eliminate and
prevent reoccurrence of such a violation.
All industrial users shall notify the PTUD, POTW, YCUA, the
EPA Regional Waste Management Division Director and the DEQ in writing
of any discharge to the sanitary sewer system of a substance that
would be a regulated hazardous waste under any federal statute if
disposed of otherwise. Such notice shall be given in accordance with
CFR 403.12(p).
