The following pollutants were assigned numerical limits in this IUP based
on allocating the Maximum Allowable Industrial Loading (MAIL)
determined with the Headworks Analysis (HWA) among all Industrial
Users. The total loading of each pollutant from all permitted discharges
does not exceed the MAIL. These limits do not result on over allocations.
N/A
RATIONALE#3b:
Interim Limits for IU pollutant reduction:
The following pollutants were assigned interim numerical limits in this IUP
to allow time for the industry to come compliance with final limits that will
not in over allocations.

RATIONALE#5a:
Non-Categorical Parameters where No Limit needed or assigned in an IUP:
The following pollutants were not assigned numerical limits in this IUP
because the loadings for these pollutants from this IU were less than 5% of
the MAHL. The loading of these pollutants from this RI is considered
insignificant at this time.
