The water quality standard of 10 mg/L is more stringent and controlling. I'm going to get on my soap box here for a moment. We have grossly missed the proper classification of a huge segment of the Cape Fear River for PNA/HQW long ago. I assure you the PNA status was established before these two facilities were built. So, we can also argue that when we have found a mistake in our permit limitations (I'll find that reg in the general statute if you give me time... ) we are obligated to correct the issue in the permit. All we are asking in the region is for DWQ to honor the general statute 143- 215.1(a1) and impose the 10 mg/L limit if the facility has tertiary treatment. We agree, at this point, we can't impose the tighter standards on the rest who don't have tertiary treatment, but will provide appropriate limitations upon expansion or upgrade. I'm not sure how we would explain to our good friends with CHPP that we aren't going to make our ww facilities use their tertiary filters (when they have them) to meet a PNA standard. Please, I've been battling this PNA issue for over two years... I had to explain to the CHPP steering committee, how we managed to miss this.. let's get the stakeholders involved and make sure we make a good and defendable decision on this. Please.... Thanks. Linda From: Hennessy, John Sent: Wednesday, October 26, 2011 1:21 PM To: Hunkele, Dean Cc: Gregson, Jim; Willis, Linda; Scardina, Maureen Subject: RE: DRAFT Permits: NC0065480 & NC0057703 Dean if you look at the rules for HQW (15A NCAC .02B .0244) you are correct that new discharges get a TSS limit of 10 mg/L. We have assumed that meant that was for a monthly average, and have been giving a 1.5 times value for daily maximum. However, you review the rule for expanded discharges, it reads, "All expanded NPDES wastewater discharges in High Quality Waters shall be required to provide the treatment described in Sub -Item (1)(b), except for those discharges which expand with no increase in permitted pollutant loading". So, what I took this to mean was that expanded discharges did have to meet the same 10 mg/L for TSS spelled out in 15A NCAC .02B .0224 (1)(b) that new discharges had to meet unless they could discharge at the higher volume without adding to the total TSS load. Being the new guy, and thus not sure of my interpretation, we brought the issue up at 1 Monday's staff meeting. The discussion that occurred at the meeting confirmed my interpretation. So, what that means, is that limits for an expanded discharge are based on a mass balance calculation. In this case, a doubling of the discharge from 100,000 to 200,000 reduces the concentration from 30 mg/L to 15 mg/L. The increase to 500,000 reduces to 6 mg/L so the limit then becomes the prescribed 10 mg/L. The presence of absence of tertiary filters doesn't come into play in the limit calculation, as much as we might like it to. I hope this helps explain why we used the limits that we did in the various permits that have been swirling around lately. We will be working with Planning to get the PNA/HQW issue in BIMS rectified. Let me know if you have any questions. Thanks. 2 Scardina, Maureen Subject: DRAFT Permits: NC0065480 & NC0057703 From: Scardina, Maureen Sent: Tuesday, October 25, 2011 9:00 AM To: Hunkele, Dean Cc: Gregson, Jim; Willis, Linda; Hennessy, John Subject: RE: DRAFT Permits: NC0065480 & NC0057703 Dean, See responses below. I've included an updated pdf for NC0065480 reflecting a correction to the facility location and the additional treatment components you mentioned. For NC0065480: • The address for the facility is 6606 River Road as in BIMS. It is not located within Beau Rivage Plantation nor on Hwy 421. Thank you for the clarification. The address was carried over from the current permit. I'll make the correction. • In the Description put the flow EQ pump info with the EQ tank size; put the blower info as serving the EQ & digester; add that it is a 100K single train extended aeration package plant with two blowers; tablet chlorination and dechlorination; flow meter The permit description/list of components is pulled from information provided in the renewal application. Both that and the inspection report you provided with the staff report reference 3 blowers. • Why is the stricter TSS limit not being applied to the 200K flow level as their A-to-C had tertiary filters included? Need to change #2 in the Supplement as they already have the A-to-C. They did get new TSS limit based on 15A NCAC 02B .0224(1)(c). The rule does not cover tertiary treatment and the TSS limits are being changed only for new or expanding discharges. #2 on the Supplement page will likely stay, or be modified depending on how far along they are with the construction. Once complete and we receive an engineer certification the list of components will need to transition anyway. • Do the monitoring frequencies not increase as flow increases? Not necessarily — monitoring frequency is typically based on the class of the facility. See 15A NCAC 2B .0500. Thanks Dean Hunkele, Senior Environmental Specialist Wilmington Regional Office 1 Scardina, Maureen From: Scardina, Maureen Sent: Tuesday, October 25, 2011 2:59 PM To: Hunkele, Dean Cc: Gregson, Jim; Willis, Linda; Hennessy, John Subject: NC0065480 Response Attachments: Maureen Scardina.vcf; Microsoft Word - 65480box.pdf Dean, I was able to make some quick corrections to the Supplemental sheet before Dina took the files to process for public notice. Any other tweaks may be made during the comment period. Pardon my rush but I'm running in several directions today on several projects. NC0065480: • The existing plant is only 0.100 MGD without tertiary filters, thus existing 0.100 MGD flow & TSS limits should remain. Both the 0.200 & 0.500 MGD flow limit pages are expansions and should get the new 10 & 15 TSS limits. The A-to-C for 0.200 MGD already approved had tertiary filters included along with UV, but in theory they could request an modified A-to-C to remove the filters and UV as not required and the tighter TSS limits would prevent that. John calculated the limits for the 0.200 MGD limits pages (TSS 15 & 22.5) based on the rule that covers expansions with no increase in permit pollutant loading. The 0.500 MGD limits page did get 10 & 15. John, do you have any thoughts on this? I understand what Dean is saying but based on our units interpretation of the rule.... • Would still list the dechlorination system as liquid and work in "package plant" in the opening sentence of the description so inspector knows to expect the aeration basin & secondary clarifier to be connected. Done. See attached. • Be sure to cut or change the Hwy 421, etc reference below the system description and before Item 2 in Supplement. Done. See attached. • Item 2 in Supplement should say: Operate a 0.200 MGD wastewater treatment facility following construction of As approved in A-to-C No. 065840A01 issued March 30, 2006. It is my understanding that highly unlikely the facility will ever be expanded, but definitely not to 0.500 MGD. Done. See attached. • Gotcha on the increased frequency questions and I don't see any reason to increase them at this point. 1 735/m1 4ge. Au/. A/6„e, dzkic.

Aqua has just recently implemented an Asset Management Program, Maintenance Connection, which will help identify & track needed maintenance on all of our facilities. Maintenance Connection will be linked in with our work order program & budgeting process to allow for a more thorough review & tracking of our facility maintenance needs. vvvu c+ (D Th Oap_e- in --tk) pot,m1 66-14,(cf but cm:1(AL] Ai koo--buA, ithCptZ° 1(- . Scardina, Maureen Subject: The Cape WWTP - PNA/HQW From: Scardina, Maureen Sent: Tuesday, October 11, 2011 8:05 AM To: Hunkele, Dean Subject: RE: The Cape WWTP - PNA/HQW Dean, Thank you for the link and the info. At this point, the permit classification has to match the classification in BIMS. PNAs were brought up about a year ago but no real instruction on how to implement changes in the permit and communicating them to the permittee were delved into. I have asked that PNA designated facilities up for renewal be discussed. Jeff mentioned there were some discussions with planning on putting them in BIMS but Planning was opposed to doing so...I'm sure there is probably a reason for this - but I'm not sure what that is at this point, I have a feeling it'll come up again. I'll pass on anything that comes along. I don't know about Southport. I'm being told that we can not threaten to not renew their permit. That decision isn't really mine, I can only recommend that Jim, John, Jeff & Matt come to some consensus on that issue and how to communicate that to the permittee. The Cape is due to go to public notice on 10/12.

Classification was changed on draft paper permit for NC0075540 think. Planning/Basin group was supposed to get all these fixed during the past year from what we were led to believe according to Linda. At a minimum, is should list it as a (pending classification correction/amendment) on the paper permit. think CO decided to use 10 mg/L monthly & 15 Mg/L daily for TSS even though regulation only mentions a 10. Facilities that have tertiary filters get the limit now, otherwise only new or expanded limits and speculative limits ge them. How was it that we forced Southport to abandon its plant & NC00 permit this year? I was told we told them after last renewal that we would not renew this time. Why can't we do the same here? I. Dean Hunkele, Senior Environmental Specialist Wilmington Regional Office From: Scardina, Maureen Sent: Monday, October 10, 2011 3:02 PM To: Hunkele, Dean Subject: The Cape WWTP - PNA/HQW Dean, Had a quick discussion with John and Jeff on this one this morning. Can you send me or show me where it is shown that their outfall is in PNA area? I'll poke around on my end and ask some of the other permit writers. I'm not sure who else has dealt with them but we/CO needs to discuss them and be sure we're all on the same page. I need to be able to show this somehow so that I can document any changes. It's my understanding that whether a facility is in PNA or not could change from year to year. Is there a map you use that is online? If so can you point me to the correct area? Is there a list of permits that are affected? If this is indeed in PNA then the TSS limits for the expanded limits will be changed to 10.0 mg/L. Per 15A NCAC 02B .0101 (e)(5) & 15A NCAC 02B .0224(1)(b)(i0. Will put this in the draft cover letter for their reference. The classification in the permit will remain "SC" but will be treated as HQW. On a separate note...we can't make them connect Dolphin Bay but what was decided was that we'll put in language/condition that specifies that the expanded limits only apply upon connection of....we haven't worked out the language yet....but something to that affect.

I've attached a copy of Dean's staff report for your review along with an updated draft. • The TSS limit has been re -corrected (see attached draft). Dean's staff report states in bold that the expanded permit TSS limits should be changed...perhaps I misunderstood....regardless, I've changed the expanded flow limit back to what it was. • The permit is currently classified "SC." The staff report recommended the permit be "corrected" to water classification of PNA HQW. PNA is not used currently, it is not an "official" stream class and changing the stream class isn't something done by our unit. BIMS says it's "SC." • May want to meet with Matt to since Dean mentions Matt was onboard with requiring Dolphin Bay (55107 — expires 1/31/12) to connect to this permit, The Cape (57703 — expires 12/31/11). It's not our usual procedure to hold up one permit renewal for another. Permits up for renewal are on a schedule based on their expiration dates - and are sent to notice based on those. If mgmt is okay with delaying a renewal, I'm okay with it. However...the issue of forcing Dolphin Bay to connect to The Cape (the subject draft -attached) and whether we can threaten to not renew their permit next cycle is not typically done. If so, I will need some direction. Let me know when you want to discuss this draft. It's scheduled for public notice on 10/12. Feel free to pass this onto Matt if necessary. Maureen From: Hunkele, Dean Sent: Monday, October 03, 2011 12:45 PM To: Scardina, Maureen Cc: Gregson, Jim Subject: RE: DRAFT Permit: NC0057703 The Cape Maureen, So what reason are we giving for lowering the TSS limit? It is a HQW classification, I do not know about the PNA. The Belville WWTP (NC0075540) has been listed as SC-HQW in it draft/renewal, thus assume that is how we are listing it. We are not asking that this facility be connected to anything. We are requesting that we require their Dolphin Bay facility (NC0055107) be connected to this facility by not renewing its permit next time —just like we did to Southport in 2006 which got them off-line in the past year. Reason that Matt signed off on the staff report was that he was on -board with it. We should simply notify them in this permit of our intent for Dolphin Bay to make sure everyone is clear. I would not issue the two permits separately as they are linked by our request. Otherwise, we should take back the expanded, regionalization flow from 0.4 to 0.75 at the bare minimum if not all the way back to 0.26 MGD.

Your staff report is in PDF so I was unable to copy and paste from it to address the line items you submitted. Number 1 & 2 have been addressed in this draft. Number 3 — PNA is not an official stream class so at this time we are not putting that in the permits. Number 4 —We can't force permittee to connect.

During normal operation, waste solids are wasted to the solids holding tank to be thickened by settling & decanting. Thickened sludge is tested to determine when it reaches approximately 2% solids content before hauling. McGill brings a mobile dewatering unit onsite & dewaters the sludge, adding polymer & returning the released water back to the head of the plant. The sludge is stabilized by McGill's composting process to meet the requirements of Class A Biosolids, at McGill's permitted facilities, WQ0006816 & SWC1906. TCLP analyses are kept on file at McGill & Aqua offices.
