Mr. Montebello,
The Yadkin Valley Sewer Authority(YVSA), NPDES Permit No: NC0020567, would like to request the
termination of the Industrial User Permit(IUP)for the Significant Industrial User(SIU)Weyerhaeuser NR
Company, IUP No: IWP002. YVSA was informed by the SIU that they were not going to renew their
permit in a letter dated July 2, 2021, and as the SIU has never released flow from their pretreatment
system to YVSA's collection system, YVSA is on agreement to discontinue the IUP.
As further information, since enactment of the IUP the SIU has only released domestic wastewater to
YVSA's collection system. With the installation and subsequent operation of the SIU's Reverse Osmosis
(RO) pretreatment system, the SIU was able to re-use their treated industrial wastewater for internal
purposes, thus eliminating the need to process through YVSA's wastewater treatment facility.
Sincerely,

Subject: Industrial User Pretreatment Permit IWP002
Ms. Johnston,
This letter is to inform you that Weyerhaeuser NR Co. in Elkin, North Carolina chose not to
renew our Industrial User Pretreatment Permit IWP002. Our permit expired on December 31,
2020. Our permit states that the renewal application must be submitted 90 days prior to the
expiration date. We chose not to renew this permit, as we stated in our February 3'2020
meeting. In our February 3, 2020 meeting, we informed Yadkin Valley Sewer Authority that we
were going discontinue our IUP and continue sending our septic only. We discussed that since
the requirements for our Industrial Wastewater were so stringent, that once we met those criteria,
the water was suitable for re-use within our mill for make-up water for our Pollution Control
Equipment. We (Weyerhaeuser) never utilized this permit or sent Industrial Wastewater to
YVSA for processing.
