All users of the 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 405 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 §
196-91. Concentration limits are applicable to wastewater effluents at the point just prior to discharge into the POTW ("end of pipe concentrations").

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.
|
2
|
Average daily concentrations will be as determined on a composite
sample taken from the user's daily discharge over a typical operational
and/or production day.
|
3
|
Maximum instantaneous concentrations will be as determined on
a grab sample taken from the user's discharge at any time during
the daily operational and/or production period.
|
4
|
Other substances which may be limited are:
|
A. Alkanes, alkenes and alkynes;
B. Aliphatic and aromatic alcohols and acids;
C. Aliphatic and aromatic aldehydes and ketones;
D. Aliphatic and aromatic esters;
E. Aliphatic and aromatic halogenated compounds;
F. Aliphatic and aromatic nitro, cyano and amino compounds;
I. 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;
J. Pesticides, including algicides, fungicides, herbicides, insecticides,
rodenticides, phthalates;
K. Polyaromatic and polynuclear hydrocarbons;
L. Total toxic organics, TTO, as defined in 40 CFR 433.11;
M. Toxic organic compounds regulated by Federal Pretreatment Standards;
N. Unsaturated aliphatics, including those with an aldehyde, ketone
or nitrile functional group; and/or
O. Viable pathogenic organisms from industrial processes or hospital
procedures.
The Superintendent shall have the authority to copy any record
related to wastewater discharges to the POTW.
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 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.
Solid waste grinders at or serving commercial establishments,
institutions or industries shall not discharge into the Town of Verona
POTW if there is a combined sewer overflow (CSO) on the sewer lines
conveying the waste to the POTW treatment plant.
The Town of Verona Town Board may reject a user's wastewater, on recommendation of the Superintendent, 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 §
196-124.
