(3) using the WLA worksheet according to the 2016 ammonia permitting guidance. • Updated outfall map. Section 4. Comments received on draft permit: • SELC submitted comment on behalf of MountainTrue, the North Carolina Chapter of Trout Unlimited, North Carolina Wildlife Federation, Watauga Riverkeeper, and the Southern Environmental Law Center, in regards of the temperature standard in trout waters. SELC raised Fact Sheet for Permit Renewal July 2022 -- NPDES Permit NCO035149 - Page 2 concerns about not having a temperature standard in the permit, even though the permittee expects to discharge effluent warmer than the maximum in -stream temperature allowed to protect the receiving streams' uses as trout waters. In response to this, NPDES permitting unit management discussed and decided that 100% domestic discharges do not qualify as a "heated liquid" as stated in the rule, and thus no trout water temperature standards should be applied to this permit. Section 5. Chances from draft to final• Updated the sampling location for dissolved oxygen and turbidity to effluent in A. (1), A. (2), and A. (3). Updated the sampling location for temperature to include effluent monitoring in A. (2), and A. (3).

Dear Mr. Rogers: Please accept the following comments submitted on behalf of MountainTrue, North Carolina Chapter of Trout Unlimited, North Carolina Wildlife Federation, Watauga Riverkeeper, and the Southern Environmental Law Center related to the North Carolina Department of Environmental Quality's ("DEQ") failure to apply the trout waters temperature standard in seven recently noticed draft National Pollutant Discharge Elimination System ("NPDES") permits: Laurel Seasons, Permit No. NCO038041; Mill Ridge Development, Permit No. NC0030473; Seven Devils Resort, Permit No. NC0035149; Smoketree Lodge, Permit No. NC0049174; Skyline Lodge & Village, Permit No. NC0036692; Nantahala School, Permit No. NC0067318; and Trillium Links & Village, Permit No. NC0059200. All seven permits would authorize discharges into designated trout waters.' Proper application of the trout waters temperature standard is critical to protecting trout populations in North Carolina. The permits discussed in this letter contain no temperature standard whatsoever for the receiving trout waters, even though permittees expect to discharge effluent warmer than the maximum in -stream temperature allowed to protect the receiving streams' uses as trout waters. This does not reflect DEQ's legal obligation to protect trout waters' designated use by ensuring discharges do not raise water temperature above certain limits or by too much. Inclusion of the trout waters temperature standard is especially important because DEQ has used the wrong water quality standard for temperature —the general mountain waters standard of 290C instead of the 1 Permit No. NC0038041 discharges into Laurel Fork, which is a Class C Trout water in the Watauga River Basin; Permit Nos. NC0030473 and NC0049174 discharge into a segment of the Watauga River, which is designated as a Class B, High Quality Waters, Trout water; Permit No. NC0035149 discharges into a separate section of the Watauga River that is designated as a Class C Trout water; Permit No. NC0059200 discharges to an unnamed tributary of Lake Glenville with a water quality classification of WS-III, High Quality Waters, Class B, Trout waters; Permit No. NC0036692 discharges, into Big Creek which has a classification of WS-11, High Quality Waters, Trout water; Permit No. NC0067318 discharges into Partridge Creek, which is a Class C Trout water. Charlottesville Chapel Hill Atlanta Asheville Birmingham Charleston Nashville Richmond Washington, DC trout waters standard of 20°C—when preparing its list of impaired waters under Section 303(d) of the Clean Water Act for several of the receiving streams at issue here.2 We ask that DEQ correct these deficiencies by adding limits to each permit sufficient to ensure compliance with the Trout waters temperatures standard of 20°C. I. Trout require cold, clean water to survive. Keeping water temperature in designated trout waters below certain thresholds is critically important because North Carolina's three species of trout —brook trout, brown trout, and rainbow trout —require cold, clean, oxygen -rich water to survive and thrive. Water temperature for these trout generally needs to be kept below 20°C (68°F).3 Unfortunately, past and ongoing land management practices threaten trout habitats, including by increasing stream temperatures. As we explained in our comments on North Carolina's draft 2022 Clean Water Act § 303(d) list, numerous trout streams routinely exceed safe water temperatures for trout.4 This problem is being exacerbated by climate change. By 2060, western North Carolina is predicted to see 10-20 more days each year with air temperatures above 35°C (95°F), increasing the potential for water temperatures to rise above 21.1 °C (70°F)levels that can be lethal to trout.5 This combination of past habitat loss, ongoing poor land management practices, and climate change poses an existential threat to many western North Carolina trout populations. Declines in trout populations —driven by increasing stream temperatures or otherwise — will hurt local economies. The total economic benefit of trout fishing in North Carolina is estimated at $383.3 million annually, supporting nearly 3,600 jobs.6 If trout habitats are further reduced, these economic benefits will be at risk. Overall, stream temperatures in North Carolina are increasing, and this trajectory is predicted to continue under a changing climate. To protect trout populations and the businesses that rely on them, North Carolina must take proactive steps to ensure trout waters remain sufficiently cold. 2 See, e.g., North Carolina 2022 Integrated Report at 1035 (assessing compliance with a temperature standard of 290C in sections of the Watauga River designated as Trout waters), available at https://edocs.deq nc.gov/WaterResources/DocView.aspx?dbid=0&id=2361713&cr=1. 3 Trout Species of North Carolina, Fly Fishing NC (accessed Sept. 26, 2022), https://www.flyfishingnc.com/trout- species-of-north-carolina. a S.

N II. North Carolina promulgated a temperature water quality standard to protect trout. Recognizing that trout require cold water, North Carolina exercised its authority under the Clean Water Act to develop a temperature water quality standard designed to keep trout streams cold. The Clean Water Act requires states to designate "uses" of waterbodies and promulgate standards to protect those uses. See 33 U.S.C. § 1313; 40 C.F.R. § 131.10; N.C. Gen. Stat. § 143-214.1. All waterbodies in North Carolina are subject to a temperature standard to protect their associated designated use. 15A N.C. Admin. Code 2B.0211(18). Some North Carolina waterbodies have been assigned a "trout waters" use. See 15A N.C. Admin. Code 2B.0301(b)(3) (explaining trout waters classification). The temperature standard —for both trout waters and non -trout waters —provides that water temperature is: not to exceed 2.8 degrees C (5.04 degrees F) above the natural water temperature, and in no case to exceed 29 degrees C (84.2 degrees F) for mountain and upper piedmont waters and 32 degrees C (89.6 degrees F) for lower piedmont and coastal plain Waters; the temperature for trout waters shall not be increased by more than .5 degrees C (0.9 degrees F) due to the discharge of heated liquids, but in no case to exceed 20 degrees C (68 degrees F). 15A N.C. Admin. Code 2B.0211(18). The standard has two parts —a delta limit and an absolute limit. In non -trout waters, the delta limit prohibits an increase attributable to a discharger of more than 2.8°C above the natural water temperature. The absolute limit provides that temperature shall "in no case" exceed 29°C in mountain and upper piedmont waters and 32°C in lower piedmont and coastal plain waters regardless of the presence of permitted dischargers. The trout waters standard follows this same structure: Stream temperature may not be increased "by more than .5 degrees C ... due to the discharge of heated liquids" but "in no case" shall stream temperature exceed 20°C. This makes sense because keeping trout waters below 20°C—regardless of the presence of permitted dischargers —is critical to sustaining healthy trout populations. North Carolina's temperature standard, including for trout waters, is implemented in part through NPDES permits that regulate point source discharges by setting limits and monitoring requirements for a variety of water quality characteristics. 33 U.S.C. § 1342(a). State agencies with delegated authority to administer the NPDES program, such as DEQ, are responsible for ensuring NPDES permits identify and apply the correct water quality limits for the waterbody into which the permittee will be discharging effluent. 3 III. DEQ failed to apply trout water temperature standards in draft NPDES permits currently out for comment. On Sept. 30, 2022, we filed comments noting DEQ's inconsistent application of temperature standards in five draft NPDES permits authorizing discharges into trout waters.7 In those comments, we applauded DEQ's correct application of the trout waters temperature standard in three of those permits but explained that it incorrectly applied the same standard in the other two. One of the draft permits that incorrectly applied the trout waters temperature standard has now been finalized, and we commend DEQ for rectifying its error and correctly applying the trout waters temperatures standard in the final permit. Specifically, Final Permit No. 0006564 clarifies that stream temperature -increasing discharges are prohibited when the background temperature of a receiving trout stream exceeds 20°C. See generally 15A N.C. Admin. Code 2B.0211(18) (trout streams are "in no case to exceed 20 degrees C (68 degrees F)."). Unfortunately, DEQ continues its inconsistent (and incorrect) application of the trout waters temperature standard in the seven NPDES permits at issue in this letter: None of them contains any limit to ensure compliance with the trout water temperature standard.$ For the reasons discussed above, applying and enforcing these temperature standards is not optional. Doing so is critical to sustaining healthy trout populations. As DEQ has recognized in other permits, if the background temperature of a receiving trout stream is already greater than 20°C, discharges causing further stream temperature increases will be unlawful. As noted above, DEQ corrected its approach in Final Permit No. 0006564 by prohibiting discharges that increase stream temperature if the receiving trout stream already exceeds 20°C.9 In Permit Nos. NC0030325, NC0042358, and NCO062961, DEQ correctly applied the trout waters temperature standard in the first instance by explaining in those permits that "[i]f the stream temperature exceeds 20 degrees C due to natural background conditions, the effluent cannot cause any increase in instream water temperature."10 DEQ must include that same limit in the permits at issue here: If the receiving trout stream temperature already exceeds 20°C, the permittee may not lawfully discharge effluent that will cause further increases in stream temperature. DEQ must also include a limit ensuring that discharges will not cause stream temperature to increase by more than 0.50C when the stream's background temperature is less than 20°C. This I S. Envt'l L.

Having reviewed those tables and footnotes in each of the draft permits at issue here, found on page 3 of each draft permit, we found no mention of a temperature limit. 9 Compare Draft NPDES Permit No. 0006564 (Baxter Healthcare Corp. WWTP) (Aug. 29, 2022), at 4, with NPDES Permit No. 0006564 (finalized Oct. 17, 2022), at 4 (clarifying that permittee could not increase the background temperature of the receiving stream under any circumstances if the background temperature exceeded 20°C). 10 See Draft Permit NC0030325, at 3; Draft Permit NC0042358, at 3; Draft Permit NC0062961, at 3. 2 is because the trout waters temperature standard prohibits discharges that increase stream temperature by "more than .5 degrees C (0.9 degrees F) due to the discharge of heated liquids." 15A N.C. Admin. Code 2B.0211(18). In combination, the trout waters temperature standard prohibits all discharges that cause stream temperature to increase over 20°C but allows increases of 0.5°C so long as the receiving stream remains below 20°C. Application of the trout water temperature standard is especially important here because five of the seven permit applications report maximum summer discharge temperatures higher than 20°C, the upper limit for trout water temperatures." In other words, discharges from these three facilities may risk causing or contributing to violations of the in -stream trout waters temperature standard. The other two permit renewal applications, NCO059200 and NC0035149, do not report the anticipated effluent temperatures.12 DEQ should require all applicants to report expected effluent temperatures. Nevertheless, based on the information before DEQ, inclusion of a temperature standard is justified to ensure the permittees do not violate the trout waters temperature standard. To be clear, DEQ has no authority to issue NPDES permits that do not ensure compliance with water quality standards which includes the trout waters temperature standard. See 33 U.S.C. § 13 11 (b)(1)(C) (requiring NPDES permits to include limitations "necessary to meet water quality standards"); 40 C.F.R. § 122.44(d)(1). As noted above, incorporating the trout waters temperature standard into all seven permits is also important because DEQ has failed to correctly apply this standard to the receiving waterbodies when preparing its Clean Water Act Section 303(d) list. Section 303(d) requires states to identify waterbodies that are not meeting water quality standards, investigate the reasons for noncompliance, and develop a plan to remediate those problems. For several years, DEQ has wrongly applied the water quality temperature standard for mountain waters (29°C) to the Watauga River and other designated trout waters protected by the 20°C standard. 13 The combination of these two errors —failure to include temperature standards in NPDES permits and 11 See Application No. NCO038041 for NPDES Permit to Discharge Wastewater, Laurel Seasons WWTP (rec'd Mar. 22, 2022), at 13 (showing a maximum daily summer effluent temperature of 25°C); Application No. NCO030473 for NPDES Permit to Discharge Wastewater, Mill Ridge WWTP (rec'd Mar. 23, 2022), at 13 (showing a maximum daily summer effluent temperature of 22°C); Application No. NCO049174 for NPDES Permit to Discharge Wastewater, Smoketree Lodge WWTP (rec'd Mar. 22, 2022), at 13 (showing a maximum daily summer effluent temperature of 24°C); Application No. NCO067318 for NPDES Permit to Discharge Wastewater, Nantahala School WWTP (rec'd May 27, 2022), at 11 (showing a maximum summer effluent temperature of 21°C); Application No. NCO036692 for NPDES Permit to Discharge Wastewater, Skyline Lodge & Village WWTP (rec'd July 7, 2022), at 11 (showing a maximum winter effluent temperature of 210C). We assume the Skyline Lodge application mistakenly swapped maximum winter and summer values, as the maximum summer temperature is listed as just 18.4°C, despite the average summer temperature being estimated at 19. VC. DEQ should clarify these parameters with the applicant prior to finalizing the permit. 12 The application for Permit No. NCO035149 lists all temperature parameters as "N/A." See Application No. NCO035149 for NPDES Permit to Discharge Wastewater, Seven Devils Resort WWTP (rec'd Mar. 18, 2022), at 13. The application for Permit No. NCO059200 does not disclose any effluent characteristics whatsoever. See Application No. NCO059200 for NPDES Permit to Discharge Wastewater, Trillium Links & Village WWTP (rec'd June 13, 2022). 13 See supra note 4. 5 failure to assess compliance with the correct temperature standard in the Section 303(d) context —risks jeopardizing trout populations. In summary, before finalizing these permits, DEQ must add language implementing the water quality temperature standard for trout waters. The most straightforward approach is to include language DEQ has already properly applied to other trout water discharge permits: "The instream temperature shall not be increased by more than 0.5 degrees C (0.9 degrees F) due to the discharge of heated liquids, but in no case to exceed 20 degrees C (68 degrees F). If the stream temperature exceeds 20 degrees C due to natural background conditions, the effluent cannot cause any increase in instream water temperature." This expression of the temperature standard, found in the most recent draft NPDES permit for the Buffalo Meadows WWTP, NPDES Permit No. NCO030325 (and others), correctly requires permittees to cause no further increase in temperature when stream temperature already exceeds trout water standards. IV. Conclusion North Carolina has some of the best and most at -risk trout habitat in the eastern United States. Ensuring viable trout populations persist in the future requires keeping trout streams clean and cold. To that end, DEQ must forthrightly apply the trout waters temperature standard in NPDES permits NC0038401, NC0030473, NC0035149, NC0049174, NC0067318, NC0036692, and NC0059200.

The proper identification of impaired waters is essential to improving the quality and preserving the best use of the State's waters. This is critical for people who rely on these waters for their economic livelihoods, for spiritual renewal, and for recreation. Identifying impaired waters is also critical for species that depend on clean water, like Southern Appalachian brook trout. For too long, the Department of Environmental Quality ("DEQ") has ignored exceedances of the temperature standard for trout streams when preparing its 303(d) list. As a result, the causes of these exceedances are never assessed and remediated through preparation of a Total Maximum Daily Load ("TMDL")—all to the detriment of anglers, fishing guides, and, most importantly, trout and other species that rely on cold, clean water. Climate change will only exacerbate this problem. It is past time for DEQ to begin listing waters on its 303(d) list that are exceeding the temperature standard for trout waters, consistent with DEQ's listing methodology.1 DEQ should also explain how it applies narrative water quality standards when preparing its 303(d) list and fix longstanding problems with its listing and delisting methodology and water quality monitoring program. 'See N.C. Dep't of Envd. Quality, 2022 303(d) Listing and Delisting Methodology (May 13, 2021). Using this methodology, DEQ will list a stream as impaired if (1) sample size is greater than nine and (2) there is a greater than 10% exceedance rate with at least 90% statistical confidence, or there is a greater than 10% exceedance rate with less than 90% confidence and there are more than three excursions with 90% confidence in newer data that have not been previously assessed. Id. at 4. For purposes of the 2022 303(d) list, "newer data" consists of data collected in 2019 and 2020. Charlottesville Chapel Hill Atlanta Asheville Birmingham Charleston Nashville Richmond Washington, DC I. The 303(d) listing process is critical to protecting the integrity of North Carolina's waters. Congress passed the Clean Water Act ("CWA") in 1972 to "to restore and maintain the chemical, physical, and biological integrity of the Nation's waters." 33 U.S.C. § 1251(a). To that end, Congress charged states with identifying "designated uses" for each jurisdictional waterbody within its boundaries. 33 U.S.C. § 1313(d); 40 C.F.R. § 131.10. States then set "criteria necessary to protect the uses" as water quality standards. 40 C.F.R. § 130.3.2 Water quality standards "should, wherever attainable, provide water quality for the protection and propagation of fish, shellfish and wildlife and for recreation in and on the water and take into consideration their use and value for public water supplies." Id. "Such standards serve the dual purposes of establishing the water quality goals for a specific water body and serving as the regulatory basis for establishment of water quality -based treatment controls and strategies beyond the technology -based level of treatment required by sections 301(b) and 306 of the [CWA]." Id. States "are required to set water quality standards for all waters within their boundaries regardless of the sources of the pollution entering the waters." Pronsolino v. Nastri, 291 F.3d 1123, 1127 (9th Cir. 2002). In other words, water quality standards are set without regard to existing or future sources of pollution. Water quality standards must be approved by the Environmental Protection Agency ("EPA") and are reviewed at least every three years. See 33 U.S.C. § 1313(a)—(c). If a new or revised state -promulgated water quality standard is insufficient to meet the purposes of the CWA, EPA must promulgate a sufficient water quality standard in its stead. 33 U.S.C. § 1313(c)(3). Every two years, states must identify "water quality limited segments" of jurisdictional waters within their borders and list them on their CWA § 303(d) list. See generally 33 U.S.C. § 1313(d). A "water quality limited segment" is any "segment where it is known that water quality does not meet applicable water quality standards, and/or is not expected to meet applicable water quality standards." 40 C.F.R. § 130.20). More specifically, states must identify water quality limited segments for which: (i) Technology -based effluent limitations required by [the CWA]; (ii) More stringent effluent limitations (including prohibitions) required by either State or local authority preserved by section 510 of the Act, or Federal authority (law, regulation, or treaty); and (iii) Other pollution control requirements (e.g., best management practices) required by local, State, or Federal authority are not stringent enough to implement any water quality standards applicable to such waters. 40 C.F.R. § 130.7(b) (emphasis added). "Water quality standard," as used here, includes "numeric criteria, narrative criteria, waterbody uses, and antidegradation requirements." Id. § 130.7(b)(3). States must also list water quality limited segments "for which controls on thermal z North Carolina implements this procedure by classifying waterbodies and assigning water quality standards for each classification. See N.C. Gen. Stat. § 143-214.1; 15A N.C. Admin. Code 213.0101, .0301. discharges under section 301 [of the CWA] or State or local requirements are not stringent enough to assure protection and propagation of a balanced indigenous population of shellfish, fish and wildlife." Id. § 130.7(b)(2). Once prepared, states submit draft 303(d) lists to EPA for approval. Id. § 130.7(d). EPA may not approve a list that does not meet "the requirements of [40 C.F.R.] § 130.7(b)." Id. § 130.7(d)(2). If EPA disapproves a list, it must add wrongfully omitted water quality limited segments back to the state's 303(d) list. Id. States are obligated to "establish TMDLs for the water quality limited segments identified" on that state's final 303(d) list. Id. C.F.R. § 130.7(c)(1). Total Maximum Daily Loads are developed based on a waterbody's "loading capacity" which is the "greatest amount of loading that a water can receive without violating water quality standards." 40 C.F.R. § 130.2(f). A "load" is an "amount of matter or thermal energy that is introduced into a receiving water" and "loading" is the act of introducing that matter or thermal energy into a receiving water. Id. § 130.2(e). "Loading may be either man -caused (pollutant loading) or natural (natural background loading)." Id. Once the TMDL determines the "loading capacity" of a waterbody, it allocates allowable levels of pollutant discharges among nonpoint and point sources3 via load allocations4 and wasteload allocations,5 respectively. The TMDL is the sum of the load allocations (including background conditions) and wasteload allocations. It thus protects the overall health of waterbodies by ensuring that point and nonpoint discharges are reduced to ensure compliance with water quality standards. TMDLs are also subject to EPA approval. Id. § 130.7(d). Once an approved TMDL is in place, a waterbody no longer must be listed as "impaired" on the 303(d) list. In summary, inclusion on the 303(d) list is the first step toward assessing water quality -limited segments and determining load allocations and wasteload allocations through the TMDL process to ensure water quality standards are not violated and designated uses of waterbodies are protected. II. North Carolina's 303(d) list wrongfully excludes stream segments that violate the temperature standard applicable to classified trout waters. For decades, North Carolina has had a temperature water quality standard specific to classified trout streams. Compliance with the standard is critical for keeping these streams cool enough to sustain trout populations. Many trout waters are increasingly exceeding this ' A "point source" is "any discernible, confined and discrete conveyance, including but not limited to any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock, concentrated animal feeding operation, or vessel or other floating craft, from which pollutants are or may be discharged." 33 U.S.C. § 1362(14). Point source discharges are regulated by National Pollutant Discharge Elimination System permits. Nonpoint source pollution is pollution that enters waterbodies but not via "discernible, confined, discrete conveyances." 4 A "load allocation" is the "portion of a receiving water's loading capacity that is attributed either to one of its existing or future nonpoint sources of pollution or to natural background sources." 40 C.F.R. § 130.2(g). 5 A "wasteload allocation" is the "portion of a receiving water's loading capacity that is allocated to one of its existing or future point sources of pollution." 40 C.F.R. § 130.2(g). temperature standard, threatening trout viability. Nevertheless, DEQ has consistently refused to list these impaired streams on its 303(d) list by a combination of (1) interpreting the trout waters temperature standard to only apply when thermal point sources discharge into the relevant stream segment, but then (2) failing to investigate the presence of thermal point source dischargers. This interpretation is contrary to the plain wording of the trout waters temperature standard, and inconsistent with the requirements of the CWA and how DEQ applies the standard outside of the 303(d) context. Just last year, DEQ initiated an enforcement action in North Carolina Superior Court alleging violations of the trout waters temperature standard even when no thermal point source discharges were present. DEQ correctly applied the trout waters temperature standard in that instance —the same standard it applies when preparing its 303(d) list. A. North Carolina trout depend upon cool, clean water. North Carolina is home to three types of trout: brook trout, rainbow trout, and brown trout. Only brook trout are native to the state. Recent studies "suggest that the native brook trout found in the southern Appalachians, including the mountains of western North Carolina, represent a unique strain called Southern Appalachian brook trout."6 These trout "have endured in North Carolina since the last ice age more than 10,000 years ago."7 "North Carolina mountain streams once teemed with Southern Appalachian brook trout" but 19t'- and 20t'-century logging practices decimated populations.8 "Extensive erosion and siltation from land disturbing activities limited spawning success by smothering eggs and restricting their oxygen supply, and streams that historically supported coldwater fishes were warmed due to lost canopy cover."9 Stocking of rainbow, brown, and northern -strain brook trout also began around 1900.10 These introduced species often outcompeted native brook trout, leading to further declines." Today, "the future of the wild brook trout is of concern, and since 1900, the brook trout range is thought to have declined by about 80 percent."12 Brook trout, brown trout, and rainbow trout require cold, clean, oxygen -rich water to survive and thrive. Past and ongoing land management practices continue to threaten trout habitats and these threats are exacerbated by climate change. By 2060, western North Carolina is predicted to see 10-20 more days each year with air temperatures above 35' C (95' F), increasing the chances that water temperatures will rise above 21.1' C (70' F)—levels that can be lethal to 6 N.C.

Declines in trout populations will also hurt local economies. The total economic benefit of trout fishing in North Carolina is estimated at $383.3 million annually, supporting nearly 3,600 jobs.14 If trout habitats are further reduced, these economic benefits will be at risk. B. North Carolina has specific temperature standards for trout waters. Consistent with its obligations under the CWA, DEQ has classified some mountain streams and lakes as "trout waters." See 15A N.C. Admin. Code 2B.0202(55) (defining "trout waters"). To protect that condition, DEQ assigned trout waters a temperature standard: Their temperature "shall not be increased by more than 0.5 degrees C (0.9 degrees F) due to the discharge of heated liquids, but in no case to exceed 20 degrees C (68 degrees F)." 15A N.C. Admin. Code 2B .0211(18); see also id. 2B.0301 (explaining that the "water quality standards applicable to each classification assigned are those established in the rules of Section .0200 of this Subchapter.").15 For purposes of compiling its 303(d) list, DEQ considers waters to be impaired when state water quality criteria —including temperature —are exceeded in more than 10% of samples with greater than or equal to 90% statistical confidence.16 Waterbodies that meet this numeric criterion must be listed;17 those that do not may still need to be listed if certain other conditions are met.18 DEQ's application of these requirements in compiling its draft 2022 303(d) report falls short for at least two reasons. First, it fails to apply the trout waters temperature standard to multiple classified trout waters. Second, it refuses to list trout waters as impaired even when the underlying data demonstrates impairment using DEQ's listing methodology.

Id. at 3-4. 5 C. DEQ is applying the wrong temperature standard to numerous trout streams. DEQ recognizes a 20' C limit for some trout waters in its draft 2022 303(d) list,19 but it omits this criterion for at least forty other classified trout water segments and instead applies the temperature standard for non -trout mountain and upper piedmont streams. 20 This is the wrong standard. Classified trout waters incorrectly assessed for compliance with the 29' C standard applicable in mountain and upper piedmont streams generally -but not the correct 20' C trout waters limit -include: Broad River (12498),21 Cedar Creek (12537), First Broad River (12758), Catawba River (317), Wilson Creek (1034), French Broad River (10925), Davidson River (11278), Avery Creek (11290), Mills River (11421), Pigeon River (10565), Allen Creek (10607), Jonathans Creek (10684), Cataloochee Creek (10798), North Toe River (11971 and 11974), South Toe River (12079), Cane River (12270), Valley River (3278), Cullasaja River (6497), Nantahala River (7235 and 7236), Tuckaseegee River (8610 and 8611), Board Cove Branch (8906), Wolf Creek (9098), Little Tennessee River (5606 and 5607), Flattop Branch (122), Norris Branch (204), Buffalo Creek (233), Brush Creek (290), Crab Creek (299), Dan River (6481),22 Horsepasture River (10512), Watauga River (13574 and 13605), Buckeye Creek (12430), and Yadkin River (13904, 14027, and 14028).23 North Carolina must revise its 303(d) list and sampling approach to assess compliance with the correct temperature standard -which, in classified trout streams, is 20' C. Application of the correct standard can decide whether a stream segment is listed as impaired and therefore whether the sources of impairment will be addressed through a TMDL or another process. For example, the draft 2022 303(d) list applies the temperature standard for mountain and upper piedmont waters of 29' C to the First Broad River (WS-V, Tr; AU ID:12758) and concludes that it complies relying on data from monitoring station A4800000. That data shows that this segment was sampled 53 times during the relevant time period and none of those samples exceeded 29' C.24 But twenty of those samples exceeded the trout waters temperature standard of 20' C-a 38% exceedance rate at 99% confidence.25 Applying the correct standard, this stream should be listed as impaired for temperature. DEQ must revise its approach to apply the correct temperature standard to classified trout waters and include waterbodies on its 303(d) list that are exceeding that standard consistent with its listing methodology. 19 See, e.g., N.C. Dep't of Envtl. Qual., North Carolina 2022 Draft Integrated Report at 289, https:Hedocs.deq nc.gov/WaterResources/DocView.aspx?dbid=0&id=2167748&cr=1 [hereafter "2022 Draft Integrated Report"] (finding that Shooks Creek -a classified trout water- is "[m]eeting" the "20°C" water temperature criteria based on legacy random ambient monitoring data). 20 See supra note 15. 21 The numbers provided in parentheses are the "AU ID" from the 2022 Draft Integrated Report. 22 Compounding its error, DEQ assesses compliance for this segment using the temperature standard applicable to lower piedmont and coastal plain waters (32' Q. 23 For hundreds of other classified trout waters, the 2022 Draft Integrated Report provides no indication about which temperature standard DEQ applies. 24 See N.C. Dep't of Envtl. Qual., BasinSummAMSMCPALMP20162020and20192020_20210820. 25 Id. on D. North Carolina must list trout streams that are exceeding the temperature standard. The First Broad River is not the only trout stream exceeding the trout waters temperature standard but omitted from the draft 2022 303(d) list. The data DEQ used to prepare the draft 2022 303(d) list shows that multiple classified trout waters with ten or more sample results are exceeding the trout waters temperature standard more than 10% of the time at greater than 90% confidence level. DEQ must list these streams on its 2022 303(d) list. Monitoring locations showing exceedances of the trout waters temperature standard include: • First Broad River (A4800000)26 — 38% exceedance with 99% confidence level • Cane River (E9850000) — 32% exceedance with 99% confidence level • North Toe River (E8100000) — 28% exceedance with 99% confidence level • Valley River (F4000000) — 25% exceedance with 97% confidence level • French Broad River (E0150000) — 25% exceedance with 99% confidence level • Pigeon River (E54950000) — 23% exceedance with 99% confidence level • Davidson River (E0850000) — 2 1 % exceedance with 98% confidence level • South Toe River (E8200000) — 21% exceedance with 95% confidence level • Horsepasture River (H6000000) — 20% exceedance with 93% confidence level • North Toe River (E7000000) — 18% exceedance with 92% confidence level. E. North Carolina's trout waters temperature standard is not dependent on the presence of thermal dischargers. Many of these streams have exceeded the trout waters temperature standard for multiple 303(d) listing cycles but have never been listed.27 Indeed, members of the public have been raising this concern with DEQ since at least 2008.28 In response, DEQ has explained that it "interprets [the trout waters temperature] standard to only be assessed with thermal discharges," i.e., thermal point source discharges subject to National Pollutant Discharge Elimination System ("NPDES") permits.29 This interpretation is contrary to the plain wording of the standard and the requirements of the CWA, and it is inconsistent with how DEQ and other state agencies apply the standard outside of the 303(d) context. First, the plain wording of the temperature standard leaves no doubt that it applies regardless of the presence of thermal discharges. In full, the standard states: 26 Data was collected at the monitoring stations provided in parentheses. 27 See N.C. Dep't of Envtl. Qual., 2020 303(d) list Integrated Report Data, BasinSummAMSCoalitl418and1718, https://files nc.gov/ncdeq/Water%20Quality/Planning/TMDL/303d/2020/2020_DATA.zip. 28 N.C. Dep't of Env't and Nat.

Qual., North Carolina 2020 Draft 303(d) List Public Comment Responsiveness Summary Submitted June 3, 2021, at 51, https://deq nc.gov/media/20453/download (the trout waters temperature standard "applies in its entirety to the evaluation of heated discharges"). 7 Temperature: not to exceed 2.8 degrees C (5.04 degrees F) above the natural water temperature, and in no case to exceed 29 degrees C (84.2 degrees F) for mountain and upper piedmont waters and 32 degrees C (89.6 degrees F) for lower piedmont and coastal plain waters; the temperature for trout waters shall not be increased by more than 0.5 degrees C (0.9 degrees F) due to the discharge of heated liquids, but in no case to exceed 20 degrees C (68 degrees F). 15A N.C. Admin. Code 2B .0211(18) (emphasis added). This standard embeds two prohibitions, only the first of which is dependent on the presence of thermal dischargers. The first prohibition is that thermal dischargers may not increase stream temperature by more than 0.5° C. For example, heated discharges that cause stream temperatures to increase from 17 to 18' C are not allowed. The second prohibition is that stream temperatures shall "in no case"—i.e., under no circumstances —exceed 20' C. The second prohibition is not dependent on the presence of thermal discharges but provides a temperature threshold that shall not be exceeded "in any case." This is consistent with the grammatical structure of the standard, which consists of two clauses. The first clause, related to the discharge of heated liquids, is separated from the second by a comma and a "but." The comma indicates a break from the preceding language. And use of "but" indicates that the second clause applies "notwithstanding" the first.30 In other words, notwithstanding the limit on temperature increases caused by thermal discharges, the temperature shall "in no case" exceed 20' C. The first half of the general surface -water temperature standard lends even more contextual support for enforcing the 20' C limit regardless of whether thermal point source discharges are present. The full standard starts by setting a delta limit applicable to thermal discharges: Temperature may not be increased by more than 2.8° C above baseline.31 It then immediately pivots to a limit applicable to all waters: Temperatures are "in no case to exceed" 29 or 32' C, depending on location. The trout waters standard is functionally identical: It sets a delta limit applicable to thermal discharges —temperature may not be increased by more than 0.5° C then immediately pivots to a limit applicable to all trout waters: temperatures are "in no case to exceed 20 degrees C." DEQ does not suggest that the 29 and 32' C limits only apply to thermal point source discharges. Given this context, DEQ cannot say that functionally identical language in the 200 C limit commands a completely different result. Understanding the 200 C limit to apply regardless of the presence of thermal point source dischargers is also the most logical interpretation of the trout waters temperature standard. Trout waters are subject to a more stringent temperature standard because high stream temperatures are lethal to trout. It makes little sense to subject trout to high stream temperatures attributable to 30 But, Merriam Webster (llth ed. 2003), https://www merriam-webster.com/dictionary/but. 31 Although this clause does not itself mention discharges of heated liquids, DEQ interprets this standard to prohibit thermal dischargers from increasing water temperatures by more than 2.8° C. See, e.g., Dep't of Envtl. Quality, NPDES Permit NC0000396 at 5 (Apr. 9, 2020), https://files nc.gov/ncdeq/Coal%20Ash/2020-actions/NC0000396- Final-Permit.pdf. EPA also understands the 2.8° C limit to apply to thermal discharges. See EPA, NC Thermal Water Quality Standards, https://www.epa.gov/sites/default/files/2014-12/documents/nc-thermal-wqs.pdf ("The rule limits thermal discharges to 2.8 degrees C (5.04 degrees F) above the natural water temperature and includes further restrictions based on geographic regions of the state"). N. nonpoint source discharges but prohibit the same increases in temperature attributable to point source discharges. To the contrary, the standard applies regardless of whether the pollution is caused by point or nonpoint sources. Second, DEQ's interpretation cannot be squared with the requirements of the CWA. As discussed above, the CWA requires states to identify designated uses for waterbodies and then set criteria to protect those uses. See 40 C.F.R. § 130.3. "Water quality standards reflect a state's designated uses for a water body and do not depend in any way upon the source of pollution." Pronsolino, 291 F.3d at 1137. DEQ's interpretation turns this on its head by arguing that application of North Carolina's trout waters temperature standard —and therefore protection of designated uses —turns on whether pollution is coming from point sources. North Carolina could not promulgate, and EPA could not approve, a water quality standard that restricts point source temperature pollution but allows unlimited nonpoint source temperature pollution to enter a stream because that standard would not protect the designated uses of the waterbody. North Carolina state law reaches this same conclusion: "[W]ater quality standards relate to the condition of waters as affected by the discharge of sewage, industrial wastes, or other wastes including those from nonpoint sources and other sources of water pollution." 15A N.C. Admin. Code 02B .0205 (emphasis added). Neither can DEQ argue that its trout waters temperature standard applies to point and nonpoint sources generally except in the 303(d) context where only point source discharges are relevant. States must list waterbodies on 303(d) lists that are exceeding water quality standards regardless of "whether a water body receives pollution from point sources only, nonpoint sources only, or a combination of the two." Pronsolino, 291 F.3d at 1132-33. This is consistent with EPA's "long-standing interpretation of section 303(d)" that the "listing requirement applies to waters impaired by point and/or nonpoint sources. ,32 Specific to temperature, EPA has previously advised that: [W]aterbodies that do not meet an applicable State water quality criterion for temperature or a designated use due to temperature should be listed. Listing is appropriate because the applicable water quality standard is not met. Heat, the cause of the impairment, is defined as a "pollutant" under section 502(6) of the Clean Water Act and can be allocated. It is immaterial to the listing decision whether the source of the temperature -related impairment is a thermal discharge or solar radiation. Both are sources of heat, and the heat can be allocated through the TMDL process.33 12 U.S. Envtl. Protection Agency, Decision Document for the Approval of the North Carolina Department of Environmental Quality 2018 Section 303(d) List at 4 (May 22, 2019), https://files nc.gov/ncdeq/Water%20Quality/Planning/TMDL/303d/2018/20190522-NC-208-303d-Approval- Package.pdf. ss U.S. Envtl.

Third, DEQ's interpretation of the trout waters temperature standard as only relating to temperature increases attributable to thermal point source discharges is inconsistent with how DEQ and other state agencies apply the standard outside of the 303(d) context. For instance, the North Carolina Forest Service has promulgated "performance standards for the protection of water quality during silvicultural activities." 2 N.C. Admin. Code 60C.0101. One performance measure requires "[s]hade ... [to] be retained to protect [perennial] streams from temperature fluctuations that result in a violation of a water quality standard of the Environmental Management Commission as contained in Rule 1 SA NCAC 2B . 0211." Id. 60C.0208 (emphasis added).36 While the performance measure is not specific to trout waters, it shows that the North Carolina Forest Service understands that nonpoint source pollution can cause a violation of stream temperature water quality standards. Elsewhere, DEQ itself has confirmed that the 20' C trout waters temperature standard is an absolute prohibition regardless of whether a stream is heated by point or nonpoint source discharges. With funding from EPA, DEQ completed a study in 2013 to assess risks to streams from headwater impoundments.37 There, DEQ confirmed that trout waters "have a maximum allowable [temperature] value of 20°C."38 The study ultimately found that "[d]esignated trout [ ] waters showed extremely high levels of exceedences [sic] of the 20°C maximum" with no discussion of whether those exceedances were attributable to point or nonpoint source discharges.39 Finally, and most significantly, DEQ has fled enforcement actions against private landowners for causing exceedances of the trout waters temperature standard even when no thermal point source discharges were involved. These enforcement actions thus relied on an "See U.S. Envtl. Protection Agency, Columbia and Lower Snake Rivers Temperature Total Maximum Daily Load (Aug. 13, 2021), https://www.epa.gov/system/files/documents/2021-08/tmdl-columbia-snake-temperature- 08132021.pdf, Attach. 8. 35 Id. at 33 n.9 (emphasis added). 36 See also North Carolina Forestry Best Management Practices Manual to Protect Water Quality, https://www.ncforestservice.gov/publications/BMP2021/202 INCFSBMPManual.pdf 31 See N.C.

On June 30, 2021, DEQ issued a Notice of Violation to a landowner in Surry County, North Carolina, for violations of water quality standards stemming from widespread clearing of forested lands. DEQ did not allege that the clearing activities resulted in a point source discharge but did state that: Title 15A North Carolina Administrative Code 213 .0211 (18) requires "Temperature: not to exceed 2.8 degrees C (5.04 degrees F) above the natural water temperature, and in no case to exceed 29 degrees C (84.2 degrees F) for mountain and upper piedmont waters ...; the temperature for trout waters shall not be increased by more than 0.5 degrees C (0.9 degrees F) due to the discharge of heated liquids, but in no case to exceed 20 degrees C (68 degrees F);" Forested buffers adjacent to streams are important measures in regulating water temperature of streams, particularly in shallow tributaries as exists on the subject Parcels. Clearing of the vegetated buffers may results in increased temperatures of surface waters draining to Ramey Creek and Big Pine Creek. Temperature field readings collected by DWR staff on June 28, 2021 constitute violations of NC Water Quality Standards.40 The landowner failed to rectify the violations and on August 6, 2021, DEQ filed a Verified Complaint and Motion for Preliminary Injunctive Relief in Surry County Superior Court.41 The Complaint states: Forest buffers adjacent to streams are important measures in regulating water temperature of streams. Clearing of the vegetated buffers may result in increased temperatures. In Trout Waters, the temperature is not to, in any case, "exceed 20 degrees C (68 degrees F). " 15A NCAC 2B .0211(18).42 The Verified Complaint continued by explaining that on "June 28, 2021, [DEQ] staff conducted water quality sampling. [DEQ]'s water quality samples show several temperature exceedances above the maximum allowable temperature of 20°C. 15A NCAC 2B .0211(18).9943 It explained that "clear -cutting trees near the border of streams removes shade and can cause water temperature to exceed the regulatory limit for trout waters." Shade removal is not a point source thermal discharge, though DEQ still recognized that it could contribute to violations of the temperature standard for trout waters.44 The Verified Complaint concluded by alleging that 4' Attach. 10 (emphasis added). On October 5, 2021, DEQ issued a Notice of Continuing Violation related to activities on the same parcels of land and stating more explicitly that "[t]emperature readings above 68 degrees .. .

But the enforcement action removes any doubt that DEQ understands the trout waters temperature standard to apply in situations where thermal point source discharges are not present and to prohibit all exceedances of the 20°C temperature standard. DEQ cannot take the opposite position now as it compiles its 2022 303(d) list. It must list streams as impaired where data shows the streams exceeding the trout waters temperature standard consistent with DEQ's listing methodology. F. Point source dischargers are present on or upstream of several North Carolina trout streams exceeding the trout waters temperature standard. Based on this faulty application of the trout waters temperature standard when compiling past 303(d) lists, DEQ has listed some trout streams as "Category 3a" in its 2022 Draft Integrated Report.46 Category 3a is reserved for instances "where data are insufficient to determine if a parameter is meeting or exceeding criteria."47 Presumably, these streams have been listed under Category 3a because DEQ did not assess the presence of thermal point source dischargers when compiling its 303(d) list and, because it interpreted the standard to only apply when a thermal point source discharger was present, concluded it had insufficient data to know whether the standard was exceeded. As explained above, this interpretation of North Carolina's temperature standard for trout waters is inconsistent with the CWA and DEQ's application of the standard outside of the 303(d) arena. But even under DEQ's incorrect interpretation of the standard, DEQ should have listed more segments because point source dischargers are, in fact, present on or upstream of multiple segments exceeding the trout waters temperature standard. The list provided below is not comprehensive and was compiled using information available on DEQ's "Online GIS Permits Map."48 It also does not encompass general NPDES permits. Data relevant to the French Broad River (AU ID 10925) is collected at monitoring station E0150000. That data shows a 25% exceedance rate of the trout waters temperature standard at 99% confidence level.49 NPDES Permit Nos.

Data relevant to the Horsepasture River (AU ID 10512) is collected at monitoring station H6000000. That data shows a 20% exceedance rate of the trout waters temperature standard with 93% confidence.54 NPDES Permit Nos. NCO05942151 and NCO05943956 discharge into, upstream, or into tributaries upstream of this stream segment. Neither of these permits imposes limits related to temperature except for monitoring requirements. There are two monitoring stations on the North Toe River (E7000000 and E8100000). They both show greater than 10% exceedance of the trout waters temperature standard at greater than 90% confidence level.57 Multiple hard rock mines discharge into the North Toe River. These mines have some combination of general permits, NPDES stormwater permits, and NPDES wastewater permits including but not limited to NPDES Permit Nos. 0000175, 0000361, 0084620, 58 0085839, 0000400, and 0000353.59 None of these wastewater permits appear to impose any limitation related to temperature beyond monitoring. NPDES Permit No. 0021423 also discharges into the North Toe River and lacks requirements related to temperature beyond monitoring.60 The single monitoring station on the Valley River (F4000000) also documents 25% exceedance of the trout waters temperature standard with 97% confidence .6 1 NPDES Permit No. NCO020800 discharges into the Valley River and includes no limitation on temperature discharges beyond monitoring. In conclusion, DEQ has for too long ignored its obligation to include on its 303(d) list stream segments that are exceeding the temperature standard applicable to trout waters. DEQ's data shows this standard has been exceeded more than 10% of the time at greater than 90% confidence level on multiple trout waters that DEQ has refused to list as impaired. These exceedances may be attributable to a combination of point and nonpoint source discharges. DEQ must list these streams as impaired on its 303(d) list as a first step towards addressing these exceedances. ss Attach. 16. 54 Supra note 24.

DEQ must explain how it assesses compliance with narrative water quality standards. When preparing its 303(d) list, DEQ must list those waterbodies for which existing requirements "are not stringent enough to implement any water quality standards applicable to such waters" including water quality standards based on "narrative criteria."40 C.F.R. § 130.7(b). DEQ's draft 2022 303(d) list and listing methodology fail to disclose how narrative criteria are considered in the 303(d) process. DEQ must correct this oversight. Of particular importance, North Carolina's toxic substances standard requires that "the concentration of toxic substances, either alone or in combination with other wastes, in surface waters shall not render waters injurious to aquatic life or wildlife, recreational activities, public health, or impair the waters for any designated uses." 15A N.C. Admin. Code 2B.0208(a). Compliance with this standard is critical especially for emerging contaminants, such as per- and polyfluoroalkyl substances ("PFAS"), for which DEQ has yet to promulgate a numeric water quality standard. EPA recently recognized PFAS as "an urgent public health and environmental issue facing communities across the United States."62 And DEQ has recognized that PFAS "meet the definition of `toxic substance"' under North Carolina law.63 DEQ must disclose how it is applying its narrative toxic substances water quality standards to ensure that waterbodies contaminated by PFAS (and other emerging contaminants that lack numeric water quality criteria) are properly listed on the state's 303(d) list. IV. DEQ's delisting methodology remains statistically unsound. For several years, multiple groups have pointed out flaws in DEQ's delisting methodology. Those concerns remain, and we incorporate previous comments by reference here.64 Briefly, North Carolina's methodology for delisting waters that are impaired for non- toxic pollutants is flawed because it fails to reverse the null hypothesis used for listing decisions. Stated differently, while it is appropriate to complete statistical analysis assuming stream segments are not impaired when evaluating whether a segment should be listed, that assumption must be reversed when evaluating whether a segment should be delisted because already listed segments must be presumed impaired until proven otherwise. Instead, DEQ applies the same method for both listing and delisting—whether waterbodies exceed criteria more than 10% of the time with more than 90% confidence —and attempts to cure the imbalance in statistical confidence by adding a second step to its delisting decisions. But this second step fails to cure 61 EPA, PFA Strategic Roadmap: EPA's Commitments to Action 2021-2024, at 1, available at https://www. epa. gov/system/files/documents/2021-10/pfas-roadmap_final-508.pdf. 63 Amended Complaint, N.C.

"See Letter from Spencer Scheidt, SELC, to Andy Painter, DEQ at 1-9 (Apr. 2, 2021), Attach. 23. 14 the fundamental flaw with the analysis —failure to reverse the null hypothesis —and allows DEQ to remove impaired waterbodies from the list with less statistical confidence than required to list them in the first place. At the second step, DEQ allows previously listed waters with an exceedance rate greater than 10% with but less than 90% statistical confidence to be delisted "if there are less than 2 excursions of the criterion in newer data that have not been previously assessed." 65 For those previously listed waters with less than a 10% exceedance rate, waters are delisted "if there is greater than 40% statistical confidence that there is less than a 10% exceedance of the criterion or if there are less than 3 excursions of the criterion in newer data that have not been previously assessed. ,66 On their own, these exceedance limits are arbitrary and fail to account for sample size. They also fail to bring the delisting methodology to the 90% confidence level required for sound statistical analysis.67 This has real consequences. The Cane River is an important trout stream and is also home to the endangered Appalachian elktoe mussel, both of which are threatened by turbidity and sediment deposition. In 2018, the Cane River was listed as impaired for turbidity. For the 2020 303(d) listing cycle, DEQ assessed data from forty-nine sampling events, eight of which demonstrated violations of the turbidity standard.68 Applying DEQ's listing methodology this translates to a 16.3% exceedance level with 88.8% confidence, just shy of the required 90%. Had DEQ appropriately reversed the null hypothesis, these same numbers would translate to a delisting decision confidence level of 5.2%.69 Yet because the Cane River had a greater than 10% exceedance rate with just under 90% confidence, DEQ moved to step two of its delisting methodology to consider whether "there are less than 2 excursions of the criterion in newer data that have not been previously assessed." Of the sixteen newer samples related to the 2020 303(d) list, only one demonstrated an exceedance of the turbidity standard, leading DEQ to delist the Cane River to Category 3a (insufficient data). Notably, DEQ would have needed to show one exceedance out of at least thirty-eight samples to reach a 90% confidence level for its delisting decision based on this "newer" data only. This 303(d)-listing cycle, the "newer data" under DEQ's methodology shows the Cane River was sampled eleven times and two of those samples exceeded the water quality standard for turbidity —an exceedance rate of 18%.70 Thus the Cane River continues to exceed water 65 N.C.

Had DEQ used a statistically sound delisting approach, the Cane River would never have been removed from the impaired list in the first instance and the reasons for its turbidity impairment should have been assessed and mitigated through preparation of a TMDL. Instead, it continues to routinely exceed water quality standards but remains indefinitely listed in Category 3a to the detriment of species like Appalachian elktoe that require cool, clean water to survive. DEQ also relies on the 10% exceedance rate to assess impairment for toxic pollutants. As EPA has explained, this approach is inappropriate for toxics.71 Nevertheless, DEQ has never "provided a scientifically defensible rationale to support [its] Listing Methodology for toxics."72 DEQ has failed to do so again as part of its draft 2022 303(d) list. During each of the past four 303(d) cycles EPA has rejected DWR's toxics findings and independently reviewed North Carolina's water quality data to determine whether all waterbody impairments were identified — it will be required to do so again in 2022. V. DEQ must collect data at times and locations that reveal the full extent of pollution. Finally, we reiterate and incorporate the concerns raised by several groups in comments on the 2020 303(d) list related to deficiencies in DEQ's monitoring network and sampling approach.73 Specifically, an ambient monitoring program that samples at arbitrary intervals and allows sampling to be delayed for "bad weather" with no limitation is likely to underreport exceedances for pollutants like turbidity. DEQ's ambient monitoring locations also appear to avoid some of the most problematic areas, resulting in underreporting pollution and unjustified delistings. We are mindful of limitations in agency resources and competing agency priorities, but we encourage DEQ to work to develop a more representative monitoring network. VI. Conclusion We appreciate the opportunity to submit comments on North Carolina's draft 2022 303(d) list. We request a meeting with DEQ to discuss the trout waters temperature standard. In particular, we would like to better understand DEQ's position regarding application of the standard and discuss ways to mitigate rising temperatures in trout streams. 71 U.S. Envtl.

WWTP), and NCO059421 (Sapphire Lake WWTP No. 1). Proper application of the trout waters temperature standard is critical to protecting trout populations in North Carolina. The Department of Environmental Quality (DEQ) has correctly applied the trout waters temperature standard for three of the permits, but not for two others. We ask that DEQ promptly correct these deficiencies before finalizing the permits. I. Trout require cold, clean water to survive. Keeping water temperature in designated trout waters below certain thresholds is critically important because North Carolina's three species of trout —brook trout, brown trout, and rainbow trout —require cold, clean, oxygen -rich water to survive and thrive. Water temperature for these trout generally needs to be kept below 20' C (68' F).' Unfortunately, past and ongoing land management practices threaten trout habitats, including by inducing stream temperature increases. As we explained in our comments on North Carolina's draft 2022 Clean Water Act § 303(d) list, numerous trout streams routinely exceed safe water temperatures for trout.2 This problem is being exacerbated by climate change. By 2060, western North Carolina is predicted to see 10-20 more days each year with air temperatures above 35' C (95' F), increasing the potential for water temperatures to rise above 21.10 C (70' F)—levels that can be 1 Trout Species of North Carolina, Fly Fishing NC (accessed Sept. 26, 2022), https://www.flyfishingnc.com/trout- species-of-north-carolina. 2 S.

Charlottesville Chapel Hill Atlanta Asheville Birmingham Charleston Nashville Richmond Washington, DC lethal to trout.' This combination of past habitat loss, ongoing poor land management practices, and climate change poses an existential threat to many western North Carolina trout populations. Declines in trout populations —driven by increasing stream temperatures or otherwise will hurt local economies. The total economic benefit of trout fishing in North Carolina is estimated at $383.3 million annually, supporting nearly 3,600 jobs.4 If trout habitats are further reduced, these economic benefits will be at risk. Overall, stream temperatures in North Carolina are increasing, and this trajectory is predicted to continue under a changing climate. To protect trout populations and the businesses that rely on them, North Carolina must take proactive steps to ensure trout waters remain sufficiently cold. II. North Carolina promulgated a temperature water quality standard to protect trout. Recognizing that trout require cold water, North Carolina exercised its authority under the Clean Water Act to develop a temperature water quality standard designed to keep trout streams cool. The Clean Water Act requires states to designate "uses" of waterbodies and promulgate standards to protect those uses. See 33 U.S.C. § 1313; 40 C.F.R. § 131.10; N.C. Gen. Stat. § 143-214.1. All waterbodies in North Carolina are subject to a temperature standard to protect their associated designated use. 15A N.C. Admin. Code 2B.0211(18). Some North Carolina waterbodies have been assigned a "trout waters" use. See 15A N.C. Admin. Code 213.0301(b)(3) (explaining trout waters classification). The temperature standard —for both trout waters and non -trout waters —provides that water temperature is: not to exceed 2.8 degrees C (5.04 degrees F) above the natural water temperature, and in no case to exceed 29 degrees C (84.2 degrees F) for mountain and upper piedmont waters and 32 degrees C (89.6 degrees F) for lower piedmont and coastal plain Waters; the temperature for trout waters shall not be increased by more than .5 degrees C (0.9 degrees F) due to the discharge of heated liquids, but in no case to exceed 20 degrees C (68 degrees F). 15A N.C. Admin. Code 2B.0211(18). The standard has two parts —a delta limit and an overall prohibition. In non -trout waters, the first part prohibits an increase attributable to a discharger of more than 2.8° C above the natural water temperature. Under the second part, temperature shall "in no case" exceed 29' C in mountain and upper piedmont waters and 320 C in lower piedmont and coastal plain waters regardless of the presence of permitted dischargers. 3 Emma Johnson, Climate Change Challenges Trout Industry in North Carolina, Carolina Public Press (Feb. 17, 2021), https://carolinapublicpress.org/42527/climate-change-challenges-trout-industry-in-north-carolina/.

Wildlife Res. Comm'n, Mountain Trout Fishing: Economic Impacts on and Contributions to North Carolina's Economy (2015), https://www.ncwildlife.org/Portals/0/Fishing/documents/Economic-Impacts-Trout- Fishing.pdf. OA The trout waters standard follows this same structure: Stream temperature may not be increased "by more than .5 degrees C ... due to the discharge of heated liquids" but "in no case" shall stream temperature exceed 20' C. This makes sense because keeping trout waters below 20' C—regardless of the presence of permitted dischargers —is critical to sustaining healthy trout populations. North Carolina's temperature standard, including for trout waters, is implemented in part through NPDES permits that regulate point source discharges by setting limits and monitoring requirements for a variety of water quality characteristics. 33 U.S.C. § 1342(a). State agencies with delegated authority to administer the NPDES program, such as DEQ, are responsible for ensuring NPDES permits identify and apply the correct water quality limits for the waterbody into which the permittee will be discharging effluent. III. DEQ inconsistently applies the trout waters temperature standard in draft NPDES permits currently out for comment. We commend DEQ for correctly applying the trout waters temperature standard in three recently noticed NPDES permits. But DEQ incorrectly applies this same standard in two additional permits, one of which incompletely states the discharger's obligations, while the other lacks any reference to a temperature standard whatsoever. DEQ must correct its application of the trout waters temperature standard in these final two permits. DEQ correctly applies the trout waters temperature standard in draft NPDES permits NCO030325 (Buffalo Meadows WWTP), NCO042358 (Adams Apple Condominiums WWTP), and NCO062961 (Tynecastle WWTP). All three permits authorize discharges into Class B trout waters.5 And all three explain that "instream temperature shall not be increased by more than 0.5 degrees C (0.9 degrees F) due to the discharge of heated liquids, but in no case to exceed 20 degrees C (68 degrees F)."6 Crucially, the permits explain that "[i]f the stream temperature exceeds 20 degrees C due to natural background conditions, the effluent cannot cause any increase in instream water temperature."7 Restated, all three permits recognize that trout waters may "in no case" exceed 20' C; they therefore prohibit all stream -warming discharges into trout waters already exceeding that threshold.$ We especially commend DEQ for applying the appropriate trout waters temperature standard to draft permits NCO042358 (Adams Apple Condominiums WWTP) and NCO062961 (Tynecastle WWTP), which both discharge into the Watauga River. When preparing its § 303(d) lists, DEQ has incorrectly applied the non -trout "mountain waters" temperature standard to the Watauga River which allows increases in water temperature up to 29' C.9 Those temperatures 5 See Draft Permit NC0030325, Draft Permit NC0042358, Draft Permit NC0062961. 6 See Draft Permit NC0030325, at 3 n.4; Draft Permit NC0042358, at 3; Draft Permit NC0062961, at 3. 'Id. (Emphasis added). s Id. 9 See, e,g., North Carolina 2022 Integrated Report, at 1035-36 (applying the 29' C standard to AU IDs 13574 and 13605), https://edocs.deq nc.gov/WaterResources/DocView.aspx?dbid=0&id=2361713&cr=1. can be lethal to trout, and we are pleased DEQ is appropriately applying the trout waters 200 C standard in Watauga River permits. Unfortunately, DEQ abandons this approach for Draft NPDES Permit NC0006564, which authorizes discharges from the Baxter Healthcare Corp. WWTP into the North Fork of the Catawba River —also a Class B trout water. DEQ starts out on the right foot, explaining that the "facility shall not exceed the instream water temperature of 20' C and not exceed 0.5°C above background temperature." But it missteps by including language stating that "[i]f the instream temperature exceeds 20' C upstream of the facility, the discharge will not be considered out of compliance with this permit limit based on the maximum regulatory limit of 20' C." This latter provision seems to allow increases of "0.5°C above background temperature," even if the "background temperature" already exceeds 20' C. This language must be stricken for the permit to comply with the trout water temperature standard, which requires that trout waters "in no case" exceed 200 C. In other words, the permit must be made consistent with draft NPDES permits NC0030325, NC0042358, and NC0062961, which correctly require that "[i]f the stream temperature exceeds 20 degrees C due to natural background conditions, the effluent cannot cause any increase in instream water temperature." DEQ may be able to address difficulties with meeting this standard through the schedule of compliance being developed for the Baxter Healthcare Corp. permit, but it cannot rewrite the trout waters temperature standard to authorize discharges which cause or contribute to exceedances above the 20' C threshold. Finally, Draft Permit NCO059421 authorizes the Sapphire Lake WWTP to discharge into the Horsepasture River, a designated Class C trout water.10 But this permit makes no mention of any temperature standard (beyond monitoring). DEQ must add language to this permit consistent with permits NC0030325, NC0042358, and NCO062961 requiring that "instream temperature shall not be increased by more than 0.5 degrees C (0.9 degrees F) due to the discharge of heated liquids, but in no case to exceed 20 degrees C (68 degrees F)" and explaining that "[i]f the stream temperature exceeds 20 degrees C due to natural background conditions, the effluent cannot cause any increase in instream water temperature." Applying the correct trout water temperature standard at the Sapphire Lake WWTP is critical because, as we pointed out in our comments on the draft 2022 § 303(d) list, the Horsepasture River routinely exceeds safe temperatures for trout and DEQ has consistently applied the wrong temperature standard.11 Data used in the 2022 § 303(d) process shows with a 93% confidence level that the Horsepasture River exceeds the 20' C threshold for trout waters 20% of the time.12 DEQ must investigate and address the reasons for these exceedances, including by applying the trout waters temperature standard in NPDES permits in this watershed. In the 2022 § 303(d) listing process, DEQ also incorrectly applied the water quality temperature standard for "mountain" waters ("in no case to exceed 29 degrees C") rather than trout waters ("in no case to exceed 20 degrees C") to the Horsepasture River.13 DEQ must not make the same to Draft Permit NCO059421. 11 See Attachment I at 6-7. 12 Id. at 7. is See North Carolina 2022 Integrated Report, supra note 9, at 895. 2 mistake here. Instead, it must apply the 20' C threshold in the Sapphire Lakes WWTP NPDES permit. IV. Conclusion North Carolina has some of the best and most at -risk trout habitat in the eastern United States. Ensuring viable trout populations persist in the future requires keeping trout streams clean and cold. To that end, DEQ must forthrightly apply the trout waters temperature standard in NPDES permits NC0006564 and NC0059421, as it has for permits NC0030325, NC0042358, and NCO062961.

VAN DER VAART secremry Water Resources ENVIRONMENTAL QUALITY S. JAY ZIMMEi RMAN Director Memorandum To: NPDES Complex Unit From: Tom Belnick Date: July 20, 2016 Subject: NPDES Permitting Guidance NPDES Implementation of Ammonia Criteria- Update NC has still not adopted an ammonia standard, though it is on our WQS Triennial List for next round. NC did establish ammonia chronic criteria for use in NPDES permitting back in 1989/90, which was based on EPA's 1986 criteria development document that factored in pH/Temp across three regions of the State (see attached). This evaluation resulted in ammonia chronic criteria of 1.0 mg/l NH3-N (summer) and 1.8 mg/l NH3-N (winter) for use in permitting purposes. NC implements these chronic criteria as Monthly Averages limits utilizing instream dilution. In 2002, NC developed procedures for complimentary acute permit limits (discussed below). The current ammonia permitting procedures should be as follows: • The NH3/TRC Wasteload Allocation (WLA) spreadsheet automatically calculates appropriate ammonia Monthly Average limits for summer and winter. The spreadsheet assumes a background ammonia concentration of 0.22 mg/1. • For any permit (new/renewal), always run the NH3/TRC WLA spreadsheet to verify appropriate Monthly Average Ammonia Limits for protection of aquatic life. • If the allowable ammonia concentration is greater than 35 mg/l, no limit should be imposed. • If the allowable concentration is less than 35 mg/l, then the allowable limit is needed and the spreadsheet will automatically calculate it. • For Municipal facilities, the acute limit will be expressed as a Weekly Average, and is based on multiplying the Monthly Average limit by a factor of 3. • For non -Municipal facilities, the acute limit will be expressed as a Daily Maximum, and is based on multiplying the Monthly Average limit by a factor of 5. • If a new more stringent ammonia limit is required, discuss the need for a Compliance Schedule with senior staff and then with the Permitee. • There is no RPA procedure used for ammonia; it is implemented strictly based on WLA spreadsheet results (similar to TRC). State of North Carolina I Environmental Quality I Water Resources 1617 Mail Service Center I Raleigh, North Carolina 27699-1617 919 707 9000 Page 12 • A sample NH3/TRC WLA is attached. In this example, the spreadsheet indicates that Monthly Average ammonia limits of 3.2 mg/1 and 12.7 mg/1 should be imposed for summer and winter, respectively, in order to protect for NC's chronic ammonia criteria. Some additional considerations: This guidance will need to be revisited after NC formally adopts an ammonia standard for both chronic and acute aquatic life protection. In the past, some ammonia limits were based strictly on protection of our DO standard rather than ammonia toxicity, and that is why the permit writer should always verify the correct ammonia limit with any permit renewal using the WLA spreadsheet. In the past, some practices allowed for maintaining a less stringent ammonia limit if the facility was consistently passing the WET test (i.e., biology trumps chemistry). This is no longer a valid approach and EPA would object. In April 2016 EPA expressly stated that NC cannot use biology to override chemical results. EPA also disallowed the use of Action Levels in permitting, in which toxicity test results (if passing) were used to override the need for permit limits for copper/zinc/silver/iron/chloride.

(4.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS [NCGS 143-215.1 (b)] Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December 21, 2015. NOTE: This special condition supplements or supersedes the following sections within Part II of this permit (Standard Conditions for NPDES Permits): • Section B. (11.) Signatory Requirements • Section D. (2.) Reporting • Section D. (6.) Records Retention • Section E. (5.) Monitoring Reports 1. Reporting Requirements [Supersedes Section D. (2.) and Section E. [5.) (a)1 The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application. Monitoring results obtained during the previous month(s) shall be summarized for each month and submitted electronically using eDMR. The eDMR system allows permitted facilities to enter monitoring data and submit DMRs electronically using the internet. Until such time that the state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation (CROMERR), permittees will be required to submit all discharge monitoring data to the state electronically using eDMR and will be required to complete the eDMR submission by printing, signing, and submitting one signed original and a copy of the computer printed eDMR to the following address: NC DEQ / Division of Water Resources / Water Quality Permitting Section ATTENTION: Central Files 1617 Mail Service Center Raleigh, North Carolina 27699-1617 If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being physically located in an area where less than 10 percent of the households have broadband access, then a temporary waiver from the NPDES electronic reporting requirements may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be submitted to the mailing address above. See "How to Request a Waiver from Electronic Reporting" section below. Regardless of the submission method, the first DMR is due on the last day of the month following the issuance of the permit or in the case of a new facility, on the last day of the month following the commencement of discharge. Starting on December 21, 2020, the permittee must electronically report the following compliance monitoring data and reports, when applicable: • Sewer Overflow/Bypass Event Reports; Page 6 of 9 NPDES Permit NC0035149 • Pretreatment Program Annual Reports; and • Clean Water Act (CWA) Section 316(b) Annual Reports. The permittee may seek an electronic reporting waiver from the Division (see "How to Request a Waiver from Electronic Reporting" section below). 2. Electronic Submissions In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time of each electronic submission. The permittee should use the EPA's website resources to identify the initial recipient for the electronic submission. Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity (EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity for receiving electronic NPDES data [see 40 CFR 127.2(b)]. EPA plans to establish a website that will also link to the appropriate electronic reporting tool for each type of electronic submission and for each state. Instructions on how to access and use the appropriate electronic reporting tool will be available as well. Information on EPA's NPDES Electronic Reporting Rule is found at: htt www2.e a. ov com fiance final -national- oliutant-dischar e-elimination- system-npdes-electronic-rep ortin.g-rule. Electronic submissions must start by the dates listed in the "Reporting Requirements" section above. 3. How to Request a Waiver from Electronic Re ortin The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to the Division. Requests for temporary electronic reporting waivers must be submitted in writing to the Division for written approval at least sixty (60) days prior to the date the facility would be required under this permit to begin submitting monitoring data and reports. The duration of a temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring data and reports shall be submitted electronically to the Division unless the permittee re -applies for and is granted a new temporary electronic reporting waiver by the Division. Approved electronic reporting waivers are not transferrable. Only permittees with an approved reporting waiver request may submit monitoring data and reports on paper to the Division for the period that the approved reporting waiver request is effective. Information on eDMR and the application for a temporary electronic reporting waiver are found on the following web page: httR: / /deg. nc.gov/ about / divisions/ water -resources / edmr Page 7 of 9 NPDES Permit NC0035149 4. Signatory Requirements [Supplements Section B. (11.)_(b) and Supersedes Section B. I I.) Idll All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II, Section B. (11.)(a) or by a duly authorized representative of that person as described in Part II, Section B. (11.)(b). A person, and not a position, must be delegated signatory authority for eDMR reporting purposes. For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user account and login credentials to access the eDMR system. For more information on North Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please visit the following web page: http: / / deq.nc.e ov f about/ divisions/ water -resources/ edmr Certification. Any person submitting an electronic DMR using the state's eDMR system shall make the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF CERTIFICATION WILL BE ACCEPTED: "I certify, under penalty of law, that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fines and imprisonment for knowing violations." 5. Records Retention [Supplements Section D. [6.)i The permittee shall retain records of all Discharge Monitoring Reports, including eDMR submissions. These records or copies shall be maintained for a period of at least 3 years from the date of the report. This period may be extended by request of the Director at any time [40 CFR 122.411.
