FACT SHEET FOR EXPEDITED PERMIT RENEWALS
This form must be completed by Permit Writers for all expedited permits which do not require full Fact
Sheets. Expedited permits are generally simple 100% domestics (e.g., schools, mobile home parks, etc)
that can be administratively renewed with minor changes, but can include facilities with more complex
issues (Special Conditions, 303(d) listed water, toxicity testing, instream monitoring, compliance
concerns).

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
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. Changes from draft to final:
• Updated the sampling location for dissolved oxygen and turbidity to effluent in A. (1)

Re: Application of the trout waters temperature standard in draft NPDES Permit
Nos. NC0038401, NC0030473, NC0035149, NC0049174, NC0036692, NC0067318,
and NC0059200.
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.

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.

290C in sections of the Watauga River designated as Trout waters), available at

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.

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

NCO042358 (Adams Apple Condominiums WWTP), NCO062961 (Tynecastle WWTP), NC0006564 (Baxter
Healthcare Corp. WWTP), and NCO059421 (Sapphire Lake WWTP No. 1) (Sept. 30, 2022), Attachment 2.
a In recent draft permits for discharges into trout waters, temperature standards have been included in footnotes
below the table containing proposed effluent limitations. 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).

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

Mar. 22, 2022), at 13 (showing a maximum daily summer effluent temperature of 25°C); Application No.

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.

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.
Please notify Henry Gargan at hgargankselcnc.org or 828-258-2023 when DEQ issues
final versions of the above permits. We remain available as always to discuss any of these
concerns.

Re: Comments on North Carolina's Draft 2022 003(d) List
Dear Mr. McNutt:
On behalf of North Carolina Wildlife Federation, North Carolina Trout Unlimited, and
MountainTrue we are submitting comments on North Carolina's draft 2022 § 303(d) list of
impaired waters. 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.

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

trout. 13 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 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.

upper piedmont waters and 32 degrees C (89.6 degrees F) for lower piedmont and coastal plain Waters." 15A N.C.

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.

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:

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

Indeed, EPA recently prepared a TMDL to address exceedances of temperature water
quality standards promulgated to protect salmon and steelhead in the Pacific Northwest.34 That
analysis noted, as an example, that "temperature TMDLs typically identify loss of riparian shade
as a nonpoint source of heat."35
In short, to comply with the CWA, North Carolina may not 1) interpret its trout waters
temperature standard as only applicable to temperature increases caused by point source
discharges or 2) otherwise exclude effects from nonpoint source discharges when preparing
303(d) lists.
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

interpretation of the temperature standard DEQ has sought to disclaim in the 303(d) listing
context.
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

activities on the same parcels of land and stating more explicitly that "[t]emperature readings above 68 degrees .. .

the landowner remained in violation of North Carolina's water quality laws, including the
temperature standard applicable to trout streams, and asking the court to order the landowner to
prepare a "Temperature Restoration Plan" to "restore streams to the proper temperature for
trout."4s
We applaud DEQ for taking action to resolve the water quality violations in Surry
County. 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

NCO08622353 all appear to discharge into or upstream of this stream segment. None of these
permits impose limits, aside from monitoring requirements, related to temperature except Permit
No. NC0000311, which states that the "temperature of the effluent shall be such as not to cause
an increase in the temperature of the receiving stream of more than 0.5°C and in no case cause
the ambient water temperature to exceed 20°C."
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.

III. 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

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

quality standards more than 10% of the time, but DEQ proposes to keep it listed under Category
3a based on its faulty delisting methodology. 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.

Dear Mr. Rogers:
Please accept the following comments submitted on behalf of the Catawba Riverkeeper
Foundation, MountainTrue, North Carolina Chapter of Trout Unlimited, North Carolina Wildlife
Federation, Watauga Riverkeeper, and the Southern Environmental Law Center related to
application of the trout waters temperature standard in five recently noticed draft National
Pollutant Discharge Elimination System (NPDES) permits: NCO030325 (Buffalo Meadows
WWTP), NCO042358 (Adams Apple Condominiums WWTP), NCO062961 (Tynecastle
WWTP), NC0006564 (Baxter Healthcare Corp. 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

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

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.

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.
Please notify Henry Gargan at hgargankselcnc.org or 828-258-2023 when DEQ issues
final versions of NPDES permit Nos. NC0006564 and NC0059421. We remain available as
always to discuss any of these concerns.
