To Mr.Touchette:
The Division of Water Resources(DWR or the Division)received on April 27,2020 your application to
renew the subject permit. Please review carefully the attached renewal draft to ensure your understanding
of its limits and monitoring conditions,and to correct errors,if any.
Concurrent with this notification,the Division will solicit public comment on this draft by publishing a
notice in newspapers having circulation in the general Buncombe County area,as required by the NPDES
Program.Please submit your written comments(if any),to my attention,NCDEQ/DWR/NPDES no
later than June 29,2021 (approximately 30 days after receiving this document).We welcome your
written comments,but they are not mandatory.
The Division understands that SKF USA(SKF),since last renewal,has made no significant alterations to
groundwater remediation facilities or processes,and further that the subject treatment facility has remained
shut down since 2009(no discharge).At your request,we renew this permit but have updated the site map
and permit texts only.Updates include:
1. outfall location text[sup.to permit cover sheet]
2. documented WWTP treatment Class PC-1 and cited relevant regulations[Section A.(1.)]
3. included parameter codes for analytes of concern [Section A. (1.)]
4. WET-test language[Section A. (2.)]
5. text for electronic reporting requirements. [Section A. (3.)]
6. Special Condition regarding future renewal [Section A. (1.)-Footnote]
Please be advised of future renewal requirements.With any future request to renew this permit, SKF shall
include with its application all site-assessments and analytical results considered in evaluating if
discharge should continue.These shall include all records and reports compiled during the permit cycle to
determine groundwater remediation progress and/or compliance with surface water quality standards.
Database Evaluation.In keeping with current NPDES Permitting Guidance,DWR will evaluate
monitoring data by applying a reasonable potential analysis(RPA)as required by the EPA.Each
parameter of concern (POC)is considered for its potential to exceed its respective surface water-quality
standard.

A. (2.) CHRONIC TOXICITY PERMIT LIMIT(Quarterly)
[15A NCAC 02B.0200 et seq.]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 15%.
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
January,April,July,and October.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 THP3B for the Chronic Value. Additionally,DWR Form AT-
3(original) is to be sent to the following address:

A. (3.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports(DMRs) and program
reports.The final NPDES Electronic Reporting Rule was adopted and became effective on December
21,2015.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit(Standard Conditions for NPDES Permits):
• Section B.(11.) Signatory Requirements
• Section D.(2.) Reporting
• Section D.(6.) Records Retention
• Section E.(5.) Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.)and Section E.(5.)(a)1
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. The eDMR system may be
accessed at:https://deq.nc.gov/about/divisions/water-resources/edmr.
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
following address:

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. 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.
