Grease, oil and sand interceptors shall be provided when, in
the opinion of the Superintendent, they are necessary for the proper
handling of liquid wastes containing grease in excessive amounts or
any flammable wastes, sand or other harmful ingredients, except that
such interceptors shall not be required for private living quarters
or dwelling units. All interceptors shall be of a type and capacity
approved by the Superintendent and shall be located so as to be readily
and easily accessible for cleaning and inspection.
[Amended 4-4-2017 by L.L.
No. 6-2017]
A. Where preliminary treatment 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.
B. Where preliminary treatment facilities are provided for any waters
or wastes, such business shall file written proof with the Superintendent
every 90 days that the preliminary treatment facilities have been
cleaned or otherwise maintained to meet the requirements of the state,
federal or other public agencies having jurisdiction. Failure to file
written proof as provided above, signed and sworn to, every 90 days
with the Superintendent shall be deemed a violation of this chapter
and subject to the penalties provided herein.
When required by the Superintendent, the owner of any property
serviced by a building sewer carrying industrial wastes shall install
a suitable control manhole, together with such necessary meters and
other appurtenances in the building sewer to facilitate observation,
sampling and measurement of the wastes. Such manhole, when required,
shall be accessibly and safely located and shall be constructed in
accordance with plans approved by the Superintendent. The manhole
shall be installed by the owner at his expense and shall be maintained
by him so as to be safe and accessible at all times.
All measurements, tests and analyses of the characteristics
of waters and wastes to which reference is made in this Part 2 shall
be determined in accordance with the latest edition of Standard Methods
for the Examination of Water and Wastewater, published by the American
Public Health Association, and shall be determined at the control
manhole provided or from suitable samples taken at said control manhole.
In the event that no special manhole has been required, the control
manhole shall be considered to be the nearest downstream manhole in
the public sewer to the point at which the building sewer is connected.
Sampling shall be carried out by customarily accepted methods to reflect
the effect of constituents upon the sewage works and to determine
the existence of hazards to life, limb and property. The particular
analysis involved will determine whether a twenty-four-hour composite
of all outfalls of a premise is appropriate or whether a grab sample
or samples should be taken. Normally, but not always, BOD and suspended
solids analyses are determined from twenty-four-hour composites of
all outfalls, whereas pH analyses are determined from periodic grab
samples.
No statement contained in this article shall be construed as
preventing any special agreement or arrangement between the Riverhead
Sewer District and any industrial concern whereby an industrial waste
of unusual strength or character may be accepted by the Riverhead
Sewer District for treatment, subject to payment therefor by the industrial
concern.
