[Amended 8-3-1998 by L.L. No. 4-1998]
A. No person shall discharge, directly or indirectly,
into the POTW wastewater containing any of the following substances
in concentrations exceeding those specified below on either a daily
or an instantaneous basis, except by permit or as provided for in
this section. Concentration limits are applicable to wastewater effluents
at the point just prior to discharge into the POTW (end-of-pipe concentrations).

All concentrations listed for metallic substances
shall be as "total metal," which shall be defined as the value measured
in a sample acidified to a pH value of two or less, without prior
filtration.
|
|
2
|
As determined on a composite sample taken from
the user's daily discharge over a typical operational and/or production
day.
|
|
3
|
As determined on a grab sample taken from the
user's discharge at any time during the daily operational and/or production
period.

B. Other substances which may be limited are:
(2) Chemical compounds which, upon acidification, alkalinization,
oxidation or reduction, in the discharge or after admixture with wastewater
and its components in the POTW, produce toxic, flammable or explosive
compounds.
(3) Pesticides, including algicides, fungicides, herbicides,
insecticides and rodenticides.
(4) Polyaromatic hydrocarbons.
(5) Viable pathogenic organisms from industrial processes
or hospital procedures.
[Amended 8-3-1998 by L.L. No. 4-1998]

B. To assure that none of the above noted limitations
is violated, the Superintendent shall issue permits to significant
industrial users limiting the discharge of the substances noted above.
Each permit shall restrict the discharge from each significant industrial
user to a portion of the total allowable influent loading. In determining
what portion of the total of each substance that each significant
industrial user shall be allowed to discharge, the superintendent
shall consider:
(1) The quantities of each substance that are uncontrollable
because they occur naturally in wastewater.
(2) The quantities of each substance that are anthropogenic
but are nonetheless uncontrollable.
(3) Historical discharge trends.
(4) Past pollution control efforts of each significant
industrial user as compared to other significant industrial dischargers
of the same substance.
(5) Potential for growth in the POTW service area.
(6) Potential for more restrictive regulatory requirements
to be placed on the POTW discharge or sludge disposal or sludge reuse
method.
(7) Treatability of the substance. The superintendent
shall apply a minimum 10% safety factor to be protective of the POTW.
C. Permits issued in accordance with this section may allow for discharges in excess of limitations set forth under §
110-84.
Grease, oil and sand interceptors shall be provided
when, in the opinion of the Superintendent, they are necessary for
the proper handling of wastewater containing excessive amounts of
grease, flammable substances, sand or other harmful substances; except
that such interceptors shall not be required for private living quarters
or living units. All interceptors shall be of a type and capacity
approved by the Superintendent and shall be so located to be easily
accessible for cleaning and inspection. Such interceptors shall be
inspected, cleaned and repaired regularly, as needed, by the owner
at his expense.
