However, derivations from the above schedule may be authorized
by the Authority at its sole discretion, upon affirmative showing,
by the person requesting the same that such deviation will not be
harmful to the sewer system or the sewage treatment plant or cause
the plant effluent to violate its current NPDES discharge limitations.
For the purpose of this chapter, an allowable deviation may be granted
by the Authority, provided that the corresponding total loading allocated
for each objectionable substance does not exceed the maximum allowable
industrial loading limit. In no event shall any deviation allow the
total loading allocated to all industrial user for any pollutant to
exceed the maximum allowable industrial loading set forth in the most
recent local limits technical evaluation submitted by the Authority
and approved by EPA as part of the Authority's pretreatment program.
Deviations granted by the Authority shall be incorporated in the industrial
user's discharge permit. In no event shall a deviation allow a discharge
to occur that is below the federal pH standard of 5.0 S.U.
