Dear Applicant:
The Water Quality Permitting Section acknowledges the April 27, 2020 receipt of your permit renewal application and
supporting documentation. Your application will be assigned to a permit writer within the Section's NPDES WW permitting
branch. Per G.S. 150E-3 your current permit does not expire until permit decision on the application is made.
Continuation of the current permit is contingent on timely and sufficient application for renewal of the current permit. The
permit writer will contact you if additional information is required to complete your permit renewal. Please respond in a
timely manner to requests for additional information necessary to allow a complete review of the application and renewal
of the permit.
Information regarding the status of your renewal application can be found online using the Department of Environmental
Quality's Environmental Application Tracker at:

Subject: National Pollutant Discharge Elimination System (NPDES) Permit Renewal
SKF USA, Inc. —Girmes Site Remediation NC0086088
Buncombe County
Dear Ms.Thedford:
TRC Environmental Corporation (TRC) has been retained by SKF USA Inc. (SKF)to operate and maintain
the SKF—Girmes Site Groundwater System in Buncombe County near Asheville, North Carolina per an
approved Corrective Action Plan (CAP). The system began discharging treated groundwater on
March 4, 1998. Groundwater is recovered using three groundwater recovery wells, treated in an air
stripper, and discharged under the site's NPDES permit. The receiving stream is Gashes Creek, which
was classified in 1997 as a "Class C"tributary of the Swannanoa River in the French Broad River basin.
The recovery system was taken off-line in November 2009. If site conditions change, there may be a
need to put the recovery system back on-line. Therefore, SKF is requesting renewal of this NPDES
permit(NC0086088).
Since the system began operation in 1998,there have been no instances where the concentration of a
permitted parameter exceeded the limit specified in the current NPDES permit. In fact, no volatile
organic compounds(VOCs), which are the parameters of concern at this site, were detected in any of
the effluent samples collected in at least the last two years of operation.
Operating History
As groundwater recovery operations continued, the volume of water recovered declined to an average
of approximately 42,000 gallons per day(gpd) in 2009, prior to taking the system offline. Also, the
concentration of VOCs in the recovered groundwater decreased. When recovery operations began in
March 1998, the influent trichloroethene (TCE) concentration was approximately 2,900 parts per billion
(ppb), but declined to approximately 300 to 400 ppb. In an effort to increase VOC removal, in
November 2002,the system began operation in a pulsed pumping mode,with the recovery system in
operation for six to seven weeks,then shut down for the remainder of the quarter. The pulse pumping
cycles started in the beginning of January, April,July, and October of each year. When the pulsed
pumping mode of operation was initiated,the concentration of TCE in the influent increased to
approximately 1000 ppb. Pulse pumping continued through the last quarter of 2009, when in October
the influent concentration of TCE was 338 ppb. Additionally,the amount of TCE removed by the
recovery system declined over the last four years of its operation where over 80 pounds of TCE was
removed in 2007 and 22 pounds of TCE were removed during 2009. The recovery system has been off-
line since mid-November 2009 and may remain off-line pending results of periodic monitoring at the site
and Gashes Creek.

An evaluation of the effectiveness of the recovery system was conducted prior to the system being shut
down in November 2009. This evaluation included reviewing the groundwater sampling data collected
from the recovery wells and monitoring wells situated adjacent to Gashes Creek. Using flow data for
Gashes Creek,TRC performed an initial calculation to estimate VOC concentrations that could be present
in groundwater without contravening a surface water standard. The concentration of TCE that could
potentially discharge into the creek while protecting the surface water standard was significantly higher
than the VOC concentrations detected in groundwater near the creek. Periodic monitoring of select
monitoring wells near Gashes Creek, surface water and pore water along Gashes Creek is conducted to
evaluate any possible changes in the impact of the groundwater on Gashes Creek. If groundwater VOC
concentrations increase to a point that water quality standards in Gashes Creek are threatened,the
recovery system may again be put back on-line hence the need for a renewed NPDES permit.
Other Requirements
Per the instructions for NPDES renewal packages, we are including the following additional information:
• United States Geological Survey(USGS)topographical site location map (Attachment 2) indicating
the location of the outfall diffuser.
• A summary of analytical results for January, April,July, and October 2009 (see Table 2,
Attachment 1),the last four sampling events prior to taking the system offline. Please note that
these months include results for VOCs, TSS, and chronic toxicity.
Since this facility does not generate sludge or other treatment residue, a sludge management plan has
not been developed for the SKF—Girmes Site. A signed statement regarding sludge management is
presented in Attachment 4.
SKF has designated Mr. Dan O. Madison,TRC as their Authorized Representative to prepare this permit
renewal package. Mr. Madison also retains delegated signatory authority for NPDES DMR forms for this
site.
We appreciate your efforts to work with us to develop an appropriate permit for the SKF—Girmes Site
Groundwater System and look forward to discussing the permit renewal with you. If there are any
questions, please call me at [phone]/[e-mail] or Mr. Greg Touchette at
SKF at [phone]/[e-mail].
Sincerely,
TRC Environmental Corporation
