(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 W10100043) 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 William.C.McGlocklin@skf.com.

This treatment system has been in operation since 1998. Permit Issues: SKF USA Inc. is requesting permit renewal, reduction of flow rating, the elimination of TSS monitoring, and chronic toxicity testing. None of the requested changes were made, as all are germane to groundwater remediation monitoring. Facility Description: The treatment system consists of an air stripping unit, a parshall flume and effluent diffuser. COMPLIANCE REVIEW Review of the correspondence indicates that facility has a good compliance record. During previous permit cycle no NOVs were issued. Compliance Evaluation Inspection Conducted on 10/31/2010 found no violations of permit requirements or applicable regulations were observed during this inspection. Whole Effluent Toxicity (WET) Test WET requirement is a Quarterly Chronic Toxicity Pass/Fail using Ceriodaphnia at 15%. They have passed all 12 toxicity tests from January 2007 until the shutdown in November, 2009.

(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.

Sullins North Carolina Department of Environment and Natural Resources April 20, 2010 Page 2 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. L• 1 WPGVLIPMOO-701441531000041IA07014453-002.DOCX CREATIK-G 0ALANC Ms. Coleen H. Sullins North Carolina Department of Environment and Natural Resources April 20, 2010 Page 3 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. L•1 WPGVL\PJt100-7014415310000111AD7014453o02AOCX CREAT:I,NG 8ALANCE;' Ms. Coleen H. Sullins North Carolina Department of Environment and Natural Resources April 20, 2010 Page 4 — 77te variability of the pollutants in the effluent — The chemical characteristics of the treated effluent have been well documented since the systems 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. — DiIution 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 SIG — Girmes Site.
