notify the Pretreatment Coordinator as soon as possible,but in no case beyond 24 hours
after first becoming aware of the failure. Repair shall be under taken as quickly as
possible.
3. High Strength Surcharges
Notwithstanding any concentrations permitted for total suspended solids, 5 day BOD or
nitrogen ammonia stated in Part I, Section F of the Permit,the permittee shall be responsible
for the payment of high strength surcharges at rates that may be established in the future by
the Monroe City Council.
4. Total Toxic Organics
The term"Total Toxic Organics"shall mean the sum of the concentrations of each of the toxic
organic compounds listed in 40 CFR Part 433.11(e)which are found at concentrations greater
than 0.010 mg/I.
5. Total Toxic Organics Sampling
If there is a change in process which may result in discharge of Total Toxic Organics(TTO),
the permittee shall perform a TTO sampling event based on a sample that is characteristic of
the permittee's usual wastewater flow,and submit the laboratory results from this sampling
event to the City of Monroe Industrial Pretreatment Office within 45 days of the process
change.
6. Total Toxic Organics(TTO)Certification
In lieu of monitoring for TTO,the permittee may,upon submitting to the City of Monroe one
sample showing TTO compliance and a Toxic Organic Management Plan,provided no
process change affecting TTO has occurred,make the following certification every six month
compliance period:
"Based on my inquiry of the person or persons directly responsible for managing compliance
with the permit limitation for total toxic organics (TTO),I certify that,to the best of my
knowledge,no discharging of concentrated toxic organics into the wastewater has occurred
since filing of the last monitoring report.I further certify that this facility is implementing the
Toxic Organic Management Plan submitted to the City of Monroe.

PART III
Special Conditions
Industrial User Pretreatment Permit (IUP)
The certification statements are due on June 15 of each year covering the January through
June six month reporting period,and November 15 of each year covering the July through
December six month reporting period.
If the certification is not submitted for both periods within 7 days of the due date the City of
Monroe will collect TTO samples before December 31 and the permittee shall be billed for
the cost of the TTO sampling.
7. Toxic Organic Management Plan
Within sixty days of the effective date of this Industrial User Permit,the permittee shall develop
and submit to the City of Monroe a toxic organic management plan.
8. Special Reopener
The City of Monroe reserves the right to reopen and modify/change limits and or sampling
frequency as deemed necessary.
9. Sludge Management Plan
Within sixty days of the effective date of this Industrial Users Permit, the permittee shall
submit a sludge management plan to the City of Monroe.
10. Certified Operator
Pursuant to Chapter 90A-44 of North Carolina General Statutes,and upon classification of the
facility by the Certification Commission, the permittee shall employ a certified wastewater
pretreatment plant operator in responsible charge (ORC) of the wastewater treatment
facilities. Such operator must hold a certification of the type and grade equivalent to, or
greater than the classification assigned to the wastewater treatment facilities by the
Certification Commission. The permittee must also employ a certified backup operator of the
appropriate type and grade to comply with the conditions of Title 15A,Chapter 8A.0202. The
ORC of the facility must visit the wastewater facility as required; must properly manage and

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.

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.
•

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.

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)

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: Cr,Ni, Fluoride, TTO
RATIONALE#3a:
Over Allocation Prevention, with IU pollutant redaction:
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.

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.
