As listed on the IUP Limits Page(s), PART I, Section F of the IUP.
RATIONALE #1:
Review of IU Monitoring Data, with no Over Allocation situation:
The following pollutants were assigned numerical limits in this IUP based on
a review of monitoring data for the permittee to determine what ranges of
concentrations are currently being discharged. To account for sample
variability a factor was applied to the monitoring data to determine the permit
limit. Permit limits assigned by the Local IUP Control Authority can not
result in an Over Allocation situation for any pollutants.

Categorical Industrial Limits, with no Over Allocation situation:
Check here if Combined Wastestream Formula (CWF) or other categorical
limits calculations were used. If used, Please attach calculations: (see CWF
Spreadsheet, Appendix 6-F)
Were used(attach calculations)
Were not used X
The following pollutants were assigned numerical limits in this IUP based on
the categorical regulations. These limits do not result in over allocations.
Pipe 01: Ammonia, Cr, Cn-,Ni, Pb, Zn, Fluoride, TTO
RATIONALE #3a:
Over Allocation Prevention, with IU pollutant reduction:
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.
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 result in over allocations.

The following rationale was used for developing IUP Limits.
Parameter Rationale
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 IU is considered
insignificant at this time.

As listed on the IUP Limits Page(s), PART I, Section F of the IUP.
RATIONALE#1:
Review of IU Monitoring Data, with no Over Allocation situation:
The following pollutants were assigned numerical limits in this IUP based on
a review of monitoring data for the permittee to determine what ranges of
concentrations are currently being discharged. To account for sample
variability a factor was applied to the monitoring data to determine the permit
limit. Permit limits assigned by the Local IUP Control Authority can not
result in an Over Allocation situation for any pollutants.

Categorical Industrial Limits, with no Over Allocation situation:
Check here if Combined Wastestream Formula (CWF) or other categorical
limits calculations were used. If used, Please attach calculations: (see CWF
Spreadsheet, Appendix 6-F)
r -
The following pollutants were assigned numerical limits in this IUP based on
the categorical regulations. These limits do not result in over allocations.
Pipe 01: Cd, Cr, Cu, Fluoride, Pb,Ni, Ag, Zn, Cn-, TTO
RATIONALE #3a:
Over Allocation Prevention, with IU pollutant reduction:
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.
Ammonia
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 result in over allocations.

4.) Other Rationale for Limitations:
The following rationale was used for developing IUP Limits.
Parameter Rationale
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 IU is considered
insignificant at this time.

Application Form(see appendix 6-A)
C. IU Inspection form
Attach a copy of an Industrial User Inspection Form(see chapter 7) completed
by the Control Authority within the past 12 months.
D. RATIONALE FOR LIMITATIONS:
As listed on the IUP Limits Page(s), PART I, Section F of the IUP.
RATIONALE#1:
Review of IU Monitoring Data, with no Over Allocation situation:
The following pollutants were assigned numerical limits in this IUP based on
a review of monitoring data for the permittee to determine what ranges of
concentrations are currently being discharged. To account for sample
variability a factor was applied to the monitoring data to determine the permit
limit. Permit limits assigned by the Local IUP Control Authority can not
result in an Over Allocation situation for any pollutants.
1

IUP Synopsis
RATIONALE#2a:
Categorical Industrial Limits,with no Over Allocation situation:
Check here if Combined Wastestream Formula (CWF) or other categorical
limits calculations were used. If used, Please attach calculations: (see CWF
Spreadsheet, Appendix 6-F)
Were used (attach calculations) Pipe 02 X
The following pollutants were assigned numerical limits in this IUP based on
the categorical regulations. These limits do not result in over allocations.
Pipe 02: Cd, Cr, Cu, Pb, Ni, Ag, Zn, Cn-, TTO
RATIONALE#3a:
Over Allocation Prevention, with IU pollutant reduction:
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.
BOD, TSS, Ammonia
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 result in over allocations.
2

IUP Synopsis
RATIONALE#4:
4.) Other Rationale for Limitations:
The following rationale was used for developing IUP Limits.
Parameter Rationale
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 IU is considered
insignificant at this time.
Pollutant Avg SIU mg/1 Avg SIU lbs/day 5% MAHL, lbs/day
RATIONALE#5b:
Categorical Parameters with Waived Monitoring:
Monitoring is waived for the following categorical parameters (attach
documentation of waiver justification).

As listed on the IUP Limits Page(s), PART I, Section F of the IUP.
RATIONALE#1:
Review of IU Monitoring Data,with no Over Allocation situation:
The following pollutants were assigned numerical limits in this IUP based on
a review of monitoring data for the permittee to determine what ranges of
concentrations are currently being discharged. To account for sample
variability a factor was applied to the monitoring data to determine the permit
limit. Permit limits assigned by the Local IUP Control Authority can not
result in an Over Allocation situation for any pollutants.
