(a)
Upon the promulgation of a national categorical pretreatment standard, the authority
shall notify all users holding a wastewater discharge permit which may be subject
to the new standard. If the new standard is more stringent than corresponding requirements
in the permits of such users, the authority shall modify the permits to require compliance
with the new standard within the time frame prescribed by the standard. Where a user
which becomes subject to a new pretreatment standard does not hold a wastewater discharge
permit, the user shall file a completed permit application form with the authority
within 90 days after the promulgation of the new standard, unless a federal or state
statute or regulation requires that the application be filed within a shorter period
of time.
(b)
A wastewater discharge permit is subject to modification by the engineer as limitations
or requirements identified in this division are revised or upon just cause. An industrial
user shall be informed of any permit modification at least 30 days prior to the effective
date of the modification, unless federal or state law or regulation requires an earlier
effective date. Any modification in a permit shall include a reasonable time schedule
for compliance. (Ord. No. 4501, 10/13/07, Sec. 1)
