Girmes Site Remediation
Buncombe County
Class PC1
Dear Mr. McKay:
SKF USA Inc. (SKF) received the draft NPDES Permit NC 0086088 from your office on November
28, 2011. We have thoroughly reviewed the draft and have no reason to ask for any changes.
The Girmes site has been an active groundwater remediation site since March 1998. In 2009
sodium persulfate (10%) was injected through four (4) injection wells (Injection Well Permit
WI0100043) into the impacted groundwater. The injection wells will permanently be closed in
2012. Since mid-November 2009 the groundwater treatment system has been off-line and no
discharge has occurred. SKF desires to keep the NPDES Permit open in an event that site
conditions dictate that the system should be restarted. We continue to conduct groundwater and
surface water monitoring periodically at the site.
If you have any questions, please contact me at 267.436.6930, or e-mail me at
[e-mail].
Sincerely,

NPDES Permit No.NC0086088
Buncombe County
Dear Ms.Sullins:
RMT North Carolina,Inc. (RMT)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 current NPDES permit sets discharge limitations for the parameters identified in Table 1 (see
Attachment 1). The facility is also required to monitor the effluent for toxicity once per quarter and
has a chronic value limit of 15 percent. This test uses Ceriodaphnia dubia as the test organism.
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,have been detected in
any of the effluent samples collected in at least the past two years of monitoring. Concentrations of
VOCs detected in the groundwater samples collected from recovery wells and monitoring wells
located adjacent to the creek have also been declining over the past three years.

Operating History
As groundwater recovery operations have continued,the volume of water recovered has declined to
the current average of approximately 42,000 gallons per day(gpdwhen the system is in operation.
Also,the concentration of VOCs in the recovered groundwater has decreased. When recovery
operations began in March 1998,the influent trichloroethene(TCE)concentration was approximately
2,900 parts per billion(ppb),but has 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 has declined over the past 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 planned 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,RMT 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 is significantly higher than the
VOC concentrations currently detected in the monitoring and recovery wells near the creek Periodic
monitoring of select monitoring wells near Gashes Creek,surface water and pore water along Gashes
Creek will be 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 and a renewed
NPDES permit will be needed.
We believe that the monitoring data since 1998 show that the treatment system can easily reduce the
influent VOCs to concentrations below the detection limit. The concentration of total suspended
solids(TSS)is also well below the NPDES permit limit.Therefore,we request that the Division of
Water Quality(DWQ)consider the permit modifications that we have detailed below.

1. Flow-The NPDES permit is currently based on the design flow of the treatment plant.
Although the permitted flow is 0.108 million gallons per day(mgd),this flow rate is much higher
than the average or maximum daily flow from the site. The average flow for the first month of
each quarter in 2009 was 0.0229,0.0421,0.0425,and 0.0452 mgd. Therefore,we request that the
DWQ use 50,000 gpd as the flow basis for the revised permit and include monthly average limits
of 0.050 mgd and no maximum flow limit(monitor and report).
2. TSS-The site has never exceeded the permit limit of 30 milligram per liter(mg/L)and the results
have generally been no detection. Because of the nature of the water that is being discharged,we
do not believe that there is a reasonable potential for the TSS limit to be exceeded. Although
continuing the analysis of effluent samples will not provide any useful data,we understand that
TSS limits are minimum requirements on all permits.Therefore,we request that DWQ change the
monitoring frequency for TSS to once per year.
3. Chronic toxicity testing-The toxicity testing that has been conducted quarterly since operations
began in 1998 has never indicated that the discharge may cause an adverse impact to the
receiving stream. With one exception in January 2002,all test results have been reported as a
"pass"according to the bioassay procedure. All of the definitive chronic toxicity tests that have
been run have passed at a Chronic Value(ChV)significantly greater than 15 percent.Most tests
have indicated that the ChV is greater than 60 percent.This concentration is significantly higher
than the in-stream waste concentration in Gashes Creek.
40 CFR 122.44(d)(1)(ii)addresses certain requirements when determining whether a discharge
causes,or has the reasonable potential to cause,an in-stream impact. The regulation specifies
that the State must consider existing controls on point and non-point sources of pollution;the
variability of the pollutant or pollutant parameter in the effluent;the sensitivity of the species to
toxicity testing(when evaluating whole effluent toxicity);and,where appropriate,the dilution of
the effluent in the receiving water. Additional information is provided in the Technical Support
Document for Water Quality-based Toxics Control(EPA/505/2-90-001). RMT's interpretation of
these considerations is summarized below.
- Existing controls on point sources of pollution-The nature of the SKF-Girmes Site
Groundwater System precludes the possibility of chemical spills or dumps,treatment
process upsets,or other incidents that could have an adverse effect on the effluent.

Ms.Coleen H.Sullins
North Carolina Department of Environment and Natural Resources
April 20,2010

- The variability of the pollutants in the effluent-The chemical characteristics of the
treated effluent have been well documented since the system's start-up in 1998. NPDES
permit compliance testing has shown that VOCs of concern are not present in the
discharge. Testing for volatile halocarbons by Method 601 has confirmed that other
volatile pollutants are absent from the discharge as well. The static nature of the site
dictates that it is very unlikely that there is any significant variability in the site's
discharge.
- The sensitivity of the species to toxicity testing-The test organism(Ceriodaphnia dubia)
has been shown to be a species sensitive to a large number of pollutants.
- Dilution of the effluent in the receiving water-The discharge has an average flow rate
of 42,000 gpd. Therefore,the test concentration stipulated in the existing permit is
extremely conservative. Gashes Creek is not effluent-dominated at the location of the
effluent diffuser.
After conducting an examination of these four criteria,RMT believes that there is no reasonable
potential for the treated effluent to cause an in-stream excursion above the ambient concentration of
either a numeric or narrative stream standard. 40 CFR 122.44(d)(1)(v)states that"limits on whole
effluent toxicity are not necessary where the permitting authority demonstrates.. .that chemical-
specific limits for the effluent are sufficient to attain and maintain applicable numeric and narrative
State water quality standards." We believe that chemical-specific limits for the SKF-Girmes Site are
sufficient and,therefore,we request that the DWQ remove toxicity testing from the 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). 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.
