From: Pickle, Ken Sent: Friday, March 13, 2015 2:54 PM To: Kucken, Darlene Cc: Georgoulias, Bethany; Herbert, Laura C; Bennett, Bradley Subject: FW: Borg Warner NCG030075 Hi Darlene, Thanks for sending this to us last Friday and asking for comments. Bethany and I looked at this separately earlier in the week, and discussed together this morning. See our response below. Ken From: Pickle, Ken Sent: Thursday, March 12, 2015 12:45 PM To: Georgoulias, Bethany Subject: FW: Borg Warner NCG030075 1. Our thoughts with respect to the ROS request: a. We don't have a site plan, but I pulled up the facility on Google Maps: I note that the south parking lot looks like employee -only parking. Ditto the front door parking on the west. I see the grassed areas. If 1 these are draining to the Outfalls #4, S, 6, and 7 that you cite, we concur that they appear to be from non -industrial activity areas. The whole site looks pretty clean. One caution: Suggest you make sure that the permittee understands that these four outfalls are unregulated, which is different from Representative Outfall Status. He's getting both responses from DEMLR as a result of your CEI, and clarifying the distinction for him might be helpful in the future. Yes, we talked about this and they understand. b. Remaining outfalls #1, 2, 3: We're ok with your recommendation suggesting sampling for #1; and for #3 as representative of #2 and #3. Again, we don't have a site plan, but you've been there, seen the site conditions, and looked at the monitoring results. We're ok with the RO call on this. Great. 2. Here are our thoughts with respect to relief from the Tier structure requirement of monthly sampling triggered by Cu and Zn exceedances: a. Background: Clayton Creek — Class C to French Broad River — Class B. No TMDL's in the French Broad River Basin except state-wide Hg. => No special concern wrt receiving water. b. We note that AMEC is on the payroll for Borg. Darlene, you might consider requiring Borg (presumably assisted by AMEC) to submit a written engineering argument for the relief from monthly sampling. Based on the CEI perhaps it's a foregone conclusion that you will grant it. But, still, we think it's good to have documentation of the basis for our decision and to begin to build a precedent on what sorts of arguments are meaningful to us, and which ones miss the point. Good idea; they have what they need to do this. c. Such an argument by B-W should address what they have already done in response to the exceedances. I guess the wet mopping, magnet sweep, and sweeping are largely driven by cleanliness needs of the manufacturing process, not in response to stormwater pollution. Darlene, you report that they have investigated everything they can. But, what have they done in response? What action? What have they tried in order to address the exceedances? It would be good to have that in their argument for relief. You could still grant relief even if they have done nothing and if you think there's no point in further monthly sampling. But again, here's a chance to reinforce the precedent that we want folks to try something first, rather than just run to us for administrative relief. Let's first seek an engineering solution (if one is feasible) before an administrative solution. What they have done is what I mentioned in my first email — they added the pre -vent filters, started magnet and wet mopping constantly, are putting in a roof over the waste containers, did a science -based assessment of stormwater, etc. But I can truly see that this place is spotless. But I agree they can send us this in a report. d. Worrisome: the claim that rainwater contains Cu and Zn — it is possible perhaps. But their evidence appears to be that runoff from the galvanized roof contains these pollutants: I would be careful not to confuse the evidence by saying that 'rainfall' has these constituents, unless the rainfall was captured directly out of the sky. Collecting off of a galvanized (i.e. coated with zinc) roof at a facility that may have combustion processes or painting processes or metal finishing processes ALL WITH ROOF STACKS, does not establish that the rainfall is polluted at the levels detected: just that the roof runoff is. Darlene, you might consider if you want to coach them on over -interpreting the data they have. We are also aware of a few literature reports from highly urbanized areas that attribute some rainfall impurities to urban air pollution. But at the moment, the generalized extrapolation to a single manufacturing facility seems an unsupported stretch to us. Amec is actually doing testing of straight rainwater at several facilities by using an open container with no association with the roof, etc. They said they'd be glad to share these results and have already been talking with Bill Hunt. They did a water from the sky test at this facility and gave me the results. He can add this to his report. e. Summary comment: we're ok with ARO moving ahead to grant relief as proposed by Darlene. Contact either of us with any follow up. Have a great weekend!

Apologies on the delay, but Mike, Ken, and I are working against a deadline to have three draft permits for power plants ready by tomorrow, when the Department sends them to notice. Ken and I will be in touch with you on this when we get through those. Thanks!

From: Kucken, Darlene Sent: Tuesday, March 03, 2015 10:47 AM To: Georgoulias, Bethany; Pickle, Ken Cc: Herbert, Laura C; King, Melissa Subject: Borg Warner NCG030075 All, Melissa King and I conducted an inspection at the Borgwarner facility on 2/25 in response to a request for: 1. Representative Outfall Status, and 2. Relief from Tiered sampling for Zinc and Copper. I found their SWPPP in very good condition, the plant itself is spotless, and there is nothing inside or outside of the plant that I noted that seems to be impacting the Zinc and Copper levels. Matthew Wallace of amec is their engineer and he has done some very thorough investigation both inside and outside the facility. They magnet and wet mop their floors constantly every day, have filters on in -plant vents that get changed frequently, clean sweep the loading dock area, and are currently building a galvanized covered roof for the open top dumpsters which collect chips and turnings. Note that they also have a Thermal Oxidizer for on -site destruction of.process coolant and mop water. In addition, Matthew is conducting an assessment of Zn and Cu levels in rainwater and he is finding that natural rainwater has elevated levels ofi With the above in mind, I'd like to recommend the following: 1. Document in the SWPPP outlets #4, 5, 6 and 7 but not require analytical monitoring. These outlets are totally from grassed areas and parking lots and are not connected to any processing. 2. Agree that Outfails #2 & 3 are representative of each other and given that outfall #3 has higher values, only require analytical sampling on #3. There is a small corner of the building that has a new galvanized roof that does not have any coating material on it. They believe the new roof is the culprit and from what I gathered from the site, I would agree this is likely. Both outfall #2 & 3 drain this roof and the loading dock area. 3. Since the levels of Zn and Cu continue to be elevated and they have investigated everything they can, I suggest we either: . a. tell them to continue tiered sampling of just outfalls #1 & #3 for some period of time to see what happens to the levels as the new roof ages and the loading dock roof is installed, OR b. give them relief from tiered sampling and just have them continue normal sampling at outfalls #1 & #3 only (dropping requirements for outfalls 4,5,6 and 7 as noted above and to allow outfall #3 to be representative of both #2 and 3). My recommendation is option b. Please ,let me know if you have any questions and I will prepare an inspection report and letter based on your input. Thanks so much!
