Water bearing miscellaneous substances in concentrations above
the standard set for normal sewage shall not be discharged into the
Village of Webster sewerage system before a finding by the Superintendent
determines that such concentration will not adversely affect any of
the biochemical, chemical or other sewage treatment process, sewage
system or receiving waters. The following is a partial list of such
substances:
B. Elemental biomine, iodine, chlorine or fluorine.
D. Phenol and phenol compounds that convert to phenol in the sewerage
system.
E. Sulfonamides or toxic dyes (organic or mineral).
F. Berylium and berylium compounds.
G. Mercury and mercury compounds.
H. Molybdenum and molybdenum compounds.
I. All strong oxidizing agents, such as chromates, dichromates, permanganates,
peroxides, etc.
J. Any strong reducing agents causing hazardous conditions in the sewage
system.
K. Chemical compounds producing toxic, flammable or explosive gases,
either upon acidification, alkalinization, oxidation or reduction.
L. Wastes from industrial processes or hospital procedures containing
viable pathogenic organisms.
When findings of the Village of Webster show that the volume
of a single toxic industrial waste discharge or the combined toxic
industrial waste discharge of a group of industries within a single
contributory area is so large as to raise a question of the ultimate
concentration of toxic substances entering a sewage treatment plant
or in cases where it is not known that the toxic substances in the
concentrations involved will be effectively removed by the sewage
treatment plant without causing deleterious effects of any kind to
the treatment process, the treatment plant sludge or the receiving
waters after treatment, the Village of Webster may rule that separate
or special concentrations limits shall be used by the contributors
in that area. Concentration limits at variance with Federal Categorical
Pretreatment Standards will not be granted.
Upon the promulgation of final Federal Categorical Pretreatment
Standard for a particular industrial subcategory, the federal standard
for sources in that subcategory shall take precedence for and become
the limitations of that category of industrial user on the date the
federal standard becomes effective until and unless a removal credit
is given. In consideration of removal allowance, the revision of any
Categorical Pretreatment Standards to reflect treatment plant removal
of pollutants shall follow the formal process required under 40 CFR
403.7. The Superintendent shall notify all affected users of the applicable
reporting requirements.
