Subject: Transmittal Letter for Industrial User Pretreatment Permit(IUP)#0003
Dear Mr. Dixon:
Your Industrial User Pretreatment Permit(IUP#0003)is enclosed. This permit is issued in
response to your Industrial User Wastewater Survey and Application which was received by the
POTW on September 10, 2021. This permit is issued pursuant to the requirements of North
Carolina General Statute 143-215.1 and the local Sewer Use Ordinance.
I have received the letter stating that the chemicals Bis(2-ethylhexyl)phthalate, Di-n-octyl
phthalate, Aluminum, Antimony, Arsenic, Beryllium, Mercury, Molybdenum, Selenium,
Thalium, Ethylbenzene, Toluene, and Xylene are present at the facility, but absent in your
discharge as they are introduced to the filter making process well after the paper making process
that generates the process water. Therefore,these chemicals are absent in the process water that
is discharged to the sewer system.
If any parts, measurement frequencies, or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within
thirty(30)days following receipt of this letter. Unless such demand is made,this decision shall
be final and binding.
Sincerely,
Palki Desai

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.
Flow- IUP has concentration based limits.
Cadmium, Chromium, Copper, Cyanide, Lead, Nickel, Silver and
Zinc — These limits were based on the available wastewater
characteristics submitted by the permittee. The only parameter ever
receiving an "elevated" limit was Zinc which is used in the process.
This limit will remain in place. The remaining parameters were
limited near or at domestic levels depending on the allowable
amounts.

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.

Industrial User Wastewater Survey
& Permit Application
Part V, Waste Reduction Information :
State Pretreatment Rule 15A NCAC 2H.0916 (c)(1)(M) requires Significant Industrial
Users to include a description of current and projected waste reduction (pollution
prevention) activities. The codes listed are standard EPA codes found on Toxic Release
Inventory and other environmental forms. Please check all applicable codes for your
facility related to wastewater discharge.
Current Projected Code Description
X W13 Improved maintenance scheduling recordkeeping, or procedures
X W14 Changed production schedule to minimize equipment and feedstock
changeovers
W19 Other changes in operating practices (explain briefly in comments)
W21 Instituted procedures to ensure that materials do not stay in inventory
beyond shelf-life
W22 Began to test outdated material-continue to use if still effective
W23 Eliminated shelf-life requirements for stable materials
W24 Instituted better labeling procedures
X W25 Instituted clearinghouse to exchange materials that would otherwise
be discarded
W29 Other changes in Inventory control (explain briefly in comments)
X W31 Improved storage or stacking procedures
W32 Improved procedures for loading,unloading and transfer operations
X W33 Installed overflow alarms or automatic shutoff valves
X W34 Installed secondary containment
W35 Installed vapor recovery systems
W36 Implemented inspection or monitoring program of potential spill or
leak sources
W39 Other spill and leak prevention(explain briefly in comments)
W41 Increased purity of raw materials
W42 Substituted raw materials
W49 Other raw material modifications (explain briefly in comments)
X W51 Instituted recirculation within a process

Dear Mr. Lambert:
Enclosed, please find the completed SIU Inspection Form for 2021 inspection, the City of
Washington conducted on November 8, 2021. Flanders passed the inspection with no violations
for the year.
The paperwork submitted every month needs to be checked to make sure all the reported values
are legible. The pH calibration should show the standards and slope in range. Since the
inspection,the pH probe has been replaced to help with the deviations. I have also received the
update Spill/ Slug plan with the updated contact information.
Whenever there is a change of contact personal in charge of the wastewater treatment for the
facility please promptly update the contact information with the City of Washington.
If you have any questions or if I can be of any further assistance with your discharge
requirements, please feel free to call me at 252-975-9373.
Sincerely,
Palki Desai
