Subject: Wyeth, LLC (a Subsidiary of Pfizer) Permit (000022) Modifi-
cation dated January 13, 2020
Dear Mr. McGee:
In reference to the phone conversation held on Thursday, August 25, 2022 I'm
submitting the modified pages of IUP Number 000022. These changes were
made due to a letter I received on December 12, 2019 from Ms. Vivien Zhong of
the PERCS unit. As you stated, there were no records showing the submittal of
this permit with these modifications. Wyeth, LLC is operating under this modified
IUP currently.
These modifications were submitted prior to the deadline specified in Ms.
Zhong's letter. During our conversation, you deemed that with this duplicate sub-
mission with the modifications completed as requested in the afore mentioned
letter would be acceptable. This letter will serve as an approval as such. I have
included a copy of the letter from Ms. Zhong, the industry transmittal letter, and
the modified permit pages.
If there are questions about the above or enclosed information, please
contact me at [phone] or by email at [e-mail].
Sincerely,
ettua-- go41"—

Dear Ms.Jordan:
The Pretreatment, Emergency Response and Collection System (PERCS) Unit of the Division of Water
Resources has reviewed the Industrial User Pretreatment Permit(IUP) Renewals submitted by the City of
Sanford for the following Significant Industrial Users (SIU). This IUPs were received by the Division on
September 26,2019.Additional information was requested and was received on November 4 2019 and
December 9,2019.

The review indicates that with the following comments,the IUPs are adequate and meet the minimum
requirement of 15A NCAC 2H.0905 and.0916 and 40 CFR 403.8(f)(1)(iii). The allocation table,maintained
in the Division's database,has been updated accordingly.

future modification and renewals.Silver is over allocated.2019 DMR data has shown that the city's
silver influent and effluent has always been below the practical quantitative level of 1 ug/L,thus
over allocation on paper is acceptable. it is recommended to lower the IUP silver limits and keep a
close look of the city's influent silver levels.

439.16 PPES" would prevent such conflict from happening. It was also noted from page 15 of the
application that chloroform was detected thus not eligible for the monitoring waiver. Please make
sure to include such language in the special conditions. Special conditions were not included in the
submission,please incorporate any other applicable changes and resubmit it before January 31,2019.
Federal and State pretreatment regulations require the local delegated pretreatment program to
effectively control and document the discharge of wastewater from Significant/Categorical Industrial
Users to the POTW. It is the POTW's responsibility to ensure that these objectives are consistently met.
Thank you for your continued support of the Pretreatment Program. If you have any questions or
comments, please contact me at(919)707-3627[email:[e-mail].
