CHRONIC TOXICITY PERMIT LIMIT (QRTRLY) Until expansion above 0.5 MGD The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 72%. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase R Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be performed during the months of January, April, July and October. Effluent sampling for this testing 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 H Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) 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 TGP313 for the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address: Attention: North Carolina Division of Water Quality Environmental Sciences Section 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30 days after the end of the reporting period for which the report is made. Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Section at the address cited above. Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required during the following month. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring.

Sldge, Bob From: Sledge, Bob Sent: Wednesday, December 19, 2012 1:00 PM To: 'Martin Lashua' Subject: FW: SOC Document - FF Harbour Hi Martin, Here are a couple of updates — not great updates, but updates nevertheless The SOC for Fairfield Harbor is in the Director's Office. I spoke with his administrative assistant yesterday. She's assured me she has placed it under his nose and advised him there is some time sensitivity in the matter. I think our managers are getting caught up in matters associated with the change in administrations, but I expect him to sign it today. Regarding the Sugar Mountain WWTP, the options I can offer you are pretty much what we talked about earlier. The existing ammonia limit (12 mg/L) at 0.5 MGD flow was established back in the 1980s using a model that sets limits based upon predicted effects of the discharge on dissolved oxygen in the receiving stream. Another model was used later when the facility sought the expansion to 1.0 MGD. That model establishes levels protective of toxicity that may result from ammonia and chlorine (you may note they are much more restrictive). It wasn't available when the ammonia limits were first established, but when you use the model today, it suggests monthly average ammonia limits be set at 1.3 mg/L in the summer and 2.6 mg/L in the winter for the 0.5 MGD permitted discharge. The 12 mg/L limit has been retained through the years only because the facility also conducts the toxicity test. What I can offer for your consideration is removal of the toxicity monitoring requirement at the 0.5 MGD permitted flow, but only with the inclusion of tighter limits for ammonia. Those limits would be set at 2 & 4 mg/L as the summer and winter monthly average limits, with associated 10 & 20 mg/L daily maximum limits. I've only eyeballed data for the facility, but it does appear you may have trouble maintaining consistent compliance with those limits. Let me know what you'd like to do and I'll get the permit ready for issuance. I'll give you another update tomorrow regarding the SOC. For now, I'm taking off to attend a class party with my son Joshua's 41h grade class. of � Have a fine afternoon. Bob .X<•. e..

I agree with your thinking. The document was routed through our management for the Director's signature on 12/6. Everything in it is now straightforward and can't be modified because attorneys have been involved. 1 can't tell you why it's taking so long, but I'll look into it and find out. Sometimes state government works just like it's stereotyped. I'll be back in touch later in the day. On another note, the permit for Hound Ears has been signed.

From: Sledge, Bob Sent: Wednesday, November 28, 2012 1:12 PM To: Moore, Cindy; Meadows, Susan Subject: NC0022900 CWS - Sugar Mountain Hi Cindy & Susie, I goofed up on this one and didn't include you on the copies when the draft permit was prepared last month. I've attached a copy now. This one is a bit unusual. It's 100% domestic flow and it has both ammonia limits (summer only) and toxicity testing. The permittee has asked if the toxicity testing requirement can be removed from the permit. There's a cryptic note in the file 1997 where the Asheville Regional Office recommended removal of the tox test, perhaps if the facility would accept ammonia limits of 2 & 4. The note says Matt had no problem with removing the test at that time. Obviously, no action was taken during that permitting cycle. The facility seems to have a pretty good toxicity compliance history, though it's not 100% on the summary. For other parameters, there have been no reported violations during the past 3 years. Would you mind giving the question some consideration and letting me know ATU's wishes? Thank you.

I hope that email is OK for communication but sure you get bombarded with emails and paper. We would appreciate you running the concept up the flagpole so we could see what the other considerations may be and if we could live with them in exchange. Chronic toxicity is a test that can fail for so many reasons and it is a challenge. We don't anticipate any expansion at this facility in the near future. Did Bob Guerra leave? From: Sledge, Bob [mailto:bob.sledge@ncdenr.govl Sent: Monday, November 19, 2012 5:53 AM To: Martin Lashua Subject: RE: Sugar Mountain Draft NPDES Permit NC0022900 Hi Martin, I hope all is well with you and yours. I'm looking into the matter. The decision will be made primarily by our Aquatic Toxicology Unit, but there may be other permitting considerations (and personalities) at play. From looking at the file, there may be some buy in on a removal of the tox limit if the ammonia limits were set 2.0 & 4.0 mg/L summer and winter. Those are just hints from the file; I'm not in a position to offer that to you. From looking at recent data, such limits may place the facility in more compliance jeopardy than you'd be comfortable with. On a different topic, do you foresee this WWTP expanding in the future such that the 1.0 mgd set of limits would come into effect? I'll try to get you some updates on the status of some other permits we have up here. We've had some administrative problems that led to issues regarding the public notice of draft permits, which is partially the reason that some of them have been slow to move to you as final, issued permits. I hope you enjoy the holiday this week.
