All users of the Village POTW will comply with all standards
and requirements of the Act and standards and requirements promulgated
pursuant to the Act, including but not limited to 40 CFR Parts 406-471.
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. Concentration limits are applicable to wastewater
effluents at the point just prior to discharge into the POTW ("end
of pipe" concentrations).

A. Except for chromium (hex), 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.
B. As determined on a composite sample taken from the user's daily
discharge over a typical operational and/or production day.
C. Other substances which may be limited are:
(1) Alkanes, alkenes and alkynes;
(2) Aliphatic and aromatic alcohols and acids;
(3) Aliphatic and aromatic aldehydes and ketones;
(4) Aliphatic and aromatic esters;
(5) Aliphatic and aromatic halogenated compounds;
(6) Aliphatic and aromatic nitro, cyano and amino compounds;
(9) 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;
(10)
Pesticides, including algicides, fungicides, herbicides, insecticides,
rodenticides;
(12)
Polyaromatic and polynuclear hydrocarbons;
(13)
Total toxic organics (TTO), as defined in 40 CFR 433.11;
(14)
Toxic organic compounds regulated by federal pretreatment standards;
(15)
Unsaturated aliphatics, including those with an aldehyde, ketone
or nitrile functional group;
(16)
Viable pathogenic organisms from industrial processes or hospital
procedures.
The Director of Public Works shall have the authority to copy
any record related to wastewater discharges to the POTW.
Except where expressly authorized to do so by an applicable
pretreatment standard, no user shall ever increase the use of process
water or, in any other way, attempt to dilute a discharge as a partial
or complete substitute for adequate treatment to achieve compliance
with a pretreatment standard.
Grease, oil, and sand interceptors shall be provided when, in
the opinion of the Director of Public Works, 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 type and capacity approved
by the Director of Public Works 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. Materials collected shall not be reintroduced into
the sewage system. The interceptors shall be readily accessible and
open to inspection by the Director of Public Works or authorized representative
upon request, at any time.
The Director of Public Works may reject a user's wastewater,
when it is has been determined that the wastewater contains substances
or possesses characteristics which have a deleterious effect on the
POTW and its processes, or on the receiving water, or which constitute
a public nuisance or hazard.
