All users of the Town 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
through 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 or as provided for in §
125-85. 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. As determined on a grab sample taken from the user's discharge
at any time during the daily operational and/or production period.
D. Any liquid or vapor having a temperature higher than 150° F.
(65° C.), or in such quantities that the temperature at the treatment
works influent exceeds 104° F., (40° C.).
E. Any water or waste containing fats, wax, grease or oils, whether
emulsified or not, in excess of 100 milligrams per liter or containing
substances which may solidify or become viscous at temperatures between
32° and 150° F. (0° to 65° C.).
F. Any waters or wastes containing strong acid iron pickling wastes
or concentrated plating solutions, whether neutralized or not.
G. Any waters or wastes containing a toxic or poisonous substance in
sufficient quantity to injure or interfere with any sewage treatment
process, or constitute a hazard to humans or animals, or create any
hazard in the receiving waters of the sewage treatment plant.
H. Any waters or wastes containing phenols or other taste- or odor-producing
substances, in such concentrations exceeding limits which may be established
by the district operator as necessary, after treatment of the composite
sewage, to meet the requirements of the state, federal or other public
agencies of jurisdiction for such discharge to the receiving waters.
I. Any radioactive wastes or isotopes of such half-life or concentration
as may exceed limits established by the district operator in compliance
with applicable state or federal regulations.
J. Any waters or wastes having a pH in excess of 9.0 or less than 6.0.
K. Materials which exert or cause:
(1) Unusual concentrations of inert suspended solids such as, but not
limited to, Fuller's earth, lime slurries and lime residues,
or of dissolved solids such as, but not limited to, sodium chloride
and sodium sulfate.
(2) Any odor or color exceeding concentration limits which may be established
by the Town for purposes of meeting the Town's national pollution
discharge eliminations systems permit.
(3) Unusual BOD, chemical oxygen demand or chlorine requirements in such
quantities as to constitute a significant load on the sewage treatment
works.
(4) Unusual volume of flow or concentration of wastes constituting "slugs,"
as defined herein.
L. 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.
(7) Aluminum, antimony, barium, beryllium, bismuth, bromine.
(8) Chlorides, cobalt, iodine, iron, lead, molybdenim, selenium, sulfates,
tin, titanium, vanadium.
(11)
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.
(12)
Pesticides, including algicides, fungicides, herbicides, insecticides,
and rodenticides.
(14)
Polyaromatic and polynuclear hydrocarbons.
(15)
Total toxic organics (TTO), as defined in 40 CFR 433.11.
(16)
Toxic organic compounds regulated by federal pretreatment standards.
(17)
Unsaturated aliphatics, including those with an aldehyde, ketone
or nitrile functional group.
(18)
Viable pathogenic organisms from industrial processes or hospital
procedures.
The district operator shall have the authority to copy any record
related to wastewater discharges to the POTW.
Grease, oil, and sand interceptors shall be provided as 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. Grease interceptors shall be installed in
all commercial kitchen facilities serving at a minimum of one large
fueling per month. All interceptors shall be of type and capacity
approved by the district operator 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.
The Town Board may reject a user's wastewater, on recommendation of the district operator, when it 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. See §
125-119.
