The authority may establish, by regulation, maximum mass or concentration discharge
limits for any pollutant that threatens the public health, presents an endangerment
to the environment, interferes with the operation of the POTW or causes the authority
to be in violation of its NPDES permit or any state permit issued to regulate the
treatment of wastewater or the treatment or application of sludge. Such limits shall
be determined at the point where the user's wastewater is discharged to the collection
system, except where the engineer determines that a limit may be applied at the end

otherwise indicated. Compliance with all parameters may be determined from a single
grab sample. In addition, the authority shall impose the validly adopted local discharge
limits of any political subdivision for those users whose discharges are tributary
to a publicly owned treatment works of the subdivision, where the limits are applicable
in the city pursuant to an agreement between the authority and the political subdivision.
(b)
The authority may establish, by regulation or in discharge permits, standards or requirements
for discharges which are necessary to ensure user compliance with section 5-6-111; provided, that no such standard or requirement may be less stringent than applicable
federal standards and requirements. (Ord. No. 4501, 10/13/07, Sec. 1)
