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 so located as to be readily
accessible for cleaning and inspection.
Where preliminary treatment or flow-equalizing facilities are
provided for waters or wastes, they shall be maintained continuously
in satisfactory and effective operation by the owner at his/her expense.
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 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/her expense and shall be maintained by him/her
so as to be safe and accessible at all times.
All major contributing industries (as defined by 40 CFR 128.124)
having in their waste a toxic pollutant must comply with Federal Pretreatment
Standards and any other applicable requirements promulgated by the
Environmental Protection Agency in accordance with Section 307 of
the Federal Water Pollution Control Act amendments of 1972 and any
more stringent pretreatment standards necessitated by local conditions
as such acts and regulations may be amended from time to time.
