Subject: Revised Flows — Permit DRAFT v3 Review
NPDES Permit NCO080853
Nokia Groundwater Treatment System, WPCS Grade PC-1
Salem Business Park Remediation Site
3370 Old Lexington Road, Winston-Salem
Forsyth County
Ms. Dolan:
The Division of Water Quality (DWR or the Division) understands that your client, Nokia of America
Corporation (Nokia), proposes to reduce the treated discharge flowrate for renewal. Based on your email of
16Nov2023, you propose an effluent flow range of 0.060 to 0.080 MGD. We agree that this is reasonable
considering our calculated discharge average of 0.062 MGD over the previously permitted discharge cycle.
However, there is an additional change. DWR considers that receiving -stream flows recorded in the
Basinwide Information System (BIMS) are likely in error. BIMS lists stream -flow average of 0.40 cfs; 30Q2
= 0.14 cfs, 7Q10w = 0.13 cfs, and 7Q10s = 0.05 cfs. We feel these flows reflect the mainstem of Salem
Creek and do not represent the unnamed tributary (UT) at the outfall. In the absence of updated UT data,
DWR must assume zero flow conditions [7Q10 / 30Q2 = 0.0 cfs] at Outfall 001 until revised, stream flows
may be verified and submitted.
It follows that the DWR must recalculate flow -limit reasonable potential analyses (RPAs) and the instream
waste concentration (IWC) as these dictate permit limits and monitoring requirements. We therefore present
this redrafted permit (DRAFT v3) and Fact Sheet for your review and comment. You are afforded an
additional 30 days for review should you want to respond in writing.
Summary of Revisions for Renewal
Discharge flow — previously 0.302 MGD, herein recalculated for renewal as 0.062 MGD.
1. Public Notice - Because effluent flow is revised, additional Public Notice is required by EPA.
2. Receiving -Stream — discharge at the top of the drainage reflects zero flow receiving -stream
conditions [7Q10 / 30Q2 = 0.0 cfs], per USGS. Renewal assumes instream waste
concentration (IWC) = 100%.

Renewal — Draft v3 Review
Jan2024
3. Updates - Supplement to Permit Cover Sheet, other permit texts, Electronic Reporting [A. (5.)]
and the Site Map.
4. Tetrachloroethylene (PCE) — Notwithstanding the modified IWC to 100%, PCE continues to
show reasonable potential to exceed its surface water -quality standard. Monitoring therefore
continues Monthly with permit limits in accord with the RPA. Limits = 3.3 µg/L Monthly
Average (MA), and Daily Max (DM) = 6.6 µg/L (MA x 2). A Schedule of Compliance is
addressed as Special Condition A. (3.).
5. O&G —renewal revises the BIMS analytical parameter code from 00556 to 00552 (as appropriate
for industrial discharges). Renewal O&G limits are 15 mg/L (MA) and 30 mg/L (DM).
6. TSS — renewal retains 30 mg/L as DM [anti -backsliding] but adds 15 mg/L MA [EPA requires
both limits].
7. 1, 4-Dioxane effluent data do not show reasonable potential [see RPA MAX Predicted = 10 µg/L,
Allowable = 80 µg/L]. However, influent 1,4-Dioxane is NOT remediated by current treatment
technology (air striping) and reportedly originates from offsite. Therefore, renewal considers 1,4-
Dioxane a new parameter of concern [see RPA]. Monitoring is hereby revised from Quarterly to
Monthly without permit limits, to establish a viable effluent database [Table A. (1.)]. Monitoring
and reporting are subject to Special Condition A. (4.).
8. pH - added monitoring to the permit [required by EPA for all industrial discharges]

Permit NCO080853
A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
[15A NCAC 02B.0200]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality
to Ceriodaphnia dubia at an effluent concentration of 90%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the
North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure, Revised December 2010, or subsequent
versions or North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure (Revised- December
2010) or subsequent versions. The tests will be performed during the months of March, June, September,
and December. These months signify the first month of each three-month toxicity testing quarter assigned
to the facility. Effluent sampling for this testing must be obtained during representative effluent discharge
and shall be performed at the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below
the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the
two following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -December 2010) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for
the pass/fail results and THP313 for the Chronic Value. Additionally, DWR Form AT-3 (original) is to be sent
to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1623 Mail Service Center
Raleigh, NC 27699-1623
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30 days
after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is
employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required,
the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating
the facility name, permit number, pipe number, county, and the month/year of the report with the notation of
"No Flow" in the comment area of the form. The report shall be submitted to the Water Sciences Section at
the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will
be required during the following month. Assessment of toxicity compliance is based on the toxicity testing
quarter, which is the three-month time interval that begins on the first day of the month in which toxicity testing
is required by this permit and continues until the final day of the third month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Water Resources indicate potential impacts to the receiving stream, this permit may be re -opened and modified
to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls, shall
constitute an invalid test and will require immediate follow-up testing to be completed no later than the last
day of the month following the month of the initial monitoring.

Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)]
The permittee shall report discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month
and submitted electronically using eDMR. The eDMR system allows permitted facilities to
enter monitoring data and submit DMRs electronically using the internet. Until such time that
the state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting
Regulation (CROMERR), permittees will be required to submit all discharge monitoring data to
the state electronically using eDMR and will be required to complete the eDMR submission by
printing, signing, and submitting one signed original and a copy of the computer printed eDMR
to the following address:

Raleigh, North Carolina 27699-1617
Page 5 of 7

Permit NC0080853
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements
may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1,
1.1, 2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be
submitted to the mailing address above. See "How to Request a Waiver from Electronic
Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the month
following the issuance of the permit or in the case of a new facility, on the last day of the month
following the commencement of discharge.
Starting on December 21, 2025, the permittee must electronically report the following
compliance monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• Clean Water Act (CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to Request
a Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the
time of each electronic submission. The permittee should use the EPA's website resources to
identify the initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the
entity (EPA or the state authorized by EPA to implement the NPDES program) that is the
designated entity for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool
for each type of electronic submission and for each state. Instructions on how to access and use
the appropriate electronic reporting tool will be available as well. Information on EPA's
NPDES Electronic Reporting Rule is found at:
hgps://www.federalre ig ster.gov/documents/2015/10/22/2015-24954/national-pollutant-
discharge-elimination-system-npdes-electronic-reporting-rule
Electronic submissions must start by the dates listed in the "Reporting Requirements" section
above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain
an electronic reporting waiver, a permittee must first submit an electronic reporting waiver
request to the Division. Requests for temporary electronic reporting waivers must be submitted
in writing to the Division for written approval at least sixty (60) days prior to the date the
facility would be required under this permit to begin submitting monitoring data and reports.
Page 6 of 7

Permit NC0080853
The duration of a temporary waiver shall not exceed 5 years and shall thereupon expire. At
such time, monitoring data and reports shall be submitted electronically to the Division unless
the permittee re -applies for and is granted a new temporary electronic reporting waiver by the
Division. Approved electronic reporting waivers are not transferrable. Only permittees with an
approved reporting waiver request may submit monitoring data and reports on paper to the
Division for the period that the approved reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found
on the following web page: http:Hdeq.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)l
All eDMRs submitted to the permit issuing authority shall be signed by a person described in
Part II, Section B. (11.)(a) or by a duly authorized representative of that person as described in
Part II, Section B. (I 1.)(b). A person, and not a position, must be delegated signatory authority
for eDMR reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user
account and login credentials to access the eDMR system. For more information on North
Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please
visit the following web page: http:Hdeq.nc.gov/about/divisions/water-resources/edmr
