All:
I have attached 8 comment letters for your consideration —one letter addressing both general permits and seven
comment letters on eight different individual permits. All letters have significant exhibits, which are attached to the
hard copies that were mailed yesterday.
We remain disappointed that North Carolina's Phase II Stormwater Program will have no beneficial impact on
water quality and concerned that the permits authorize discharges that contravene the Clean Water Act and state
law. As discussed in more detail in the letters, discharges of stormwater pursuant to the general permits and the
individual permits, especially to sensitive waters and waters providing aquatic habitat for endangered species,
likely will cause water quality violations and degradation of existing uses. Furthermore, the Department's decision
to deem existing stormwater programs compliant with the Phase II post -construction standards is particularly
troubling, and clearly violates federal law and the Phase II session law.
As you review our letters, please do not hesitate to contact me with any questions.
Sincerely,
Amy

RE: Draft NPDES Permit No. NCS000442, Rocky Mount
Draft NPDES Permit No. NCS000437, Greenville
Dear NIr. Bennett:
Please accept these comments from the Pamlico -Tar River Foundation ("PTRF")
and the Southern Environmental Law Center ("SELC") on the draft stormwater Phase I1
NPDES permit NCS000442 for the City of Rocky Mount and NPDES permit
NCS000437 for the City of Greenville. PTRF is a grassroots organization, representing
over 1400 members, whose mission is to protect and improve the environmental quality
of the Tar -Pamlico River, its estuaries and watershed. SELC is a non-profit legal
advocacy group dedicated to protecting the environment of the South. SELC works with
more than 100 partner groups in a six state region. SELC has been actively involved in a
variety of efforts to improve water quality in the Tar -Pamlico watershed, including work
on protections for the dwarf wedge mussel.
As discussed in more detail below, the North Carolina Phase 11 stormwater
program is inadequate to protect water quality and does not fulfill the requirements of the
Clean 'rater Act. In particular, in the Tar -Pamlico basin, those cities and counties already
covered by the Tar -Pamlico Stormwater rule, 15A NCAC 02B .0258 (2004), are deemed
compliant with the Phase Il requirements for post -construction stormwater management
model practices. However, there are requirements of Phase I1 that are not included in the
Tar -Pamlico rule, including requirements for removal of Total Suspended Solids ("TSS")
and requirements to address stormwater quantity. Also, the State's stormwater regulations
have actually weakened the City of Greenville's stormwater program. The city changed
its ordinance from requiring Best Management Practices ("BMP") to address the 2, 5, and
10-year storms, to now only requiring designs for the I-yr, 24-hour storm. This is
unacceptable, irresponsible, and must be corrected before further damage is done to
public trust waterways.
In addition, the conditions and limitations in these draft permits are inadequate to
ensure compliance with water quality standards. The Clean Water Act and North
Carolina law require that all NPDES permits include limitations necessary to comply
with applicable water quality standards. North Carolina law places the burden on the
applicant to demonstrate compliance with water quality standards. Issuance of a permit
without adequate measures to protect federally listed endangered species may result in a
prohibited taking in violation of the Endangered Species Act.
I. General Comments
The Clean Water Act prohibits the discharges that violate water quality standards;
and the federal Phase 11 rules require regulated entities to "develop, implement, and
enforce a stormwater management program designed to reduce the discharge of
pollutants ... to the maximum extent practicable, to protect water quality, and to
satisfy the appropriate water quality requirements of the Clean Water Act." 40 C.F.R.
§ 122.34 (a) (emphasis added). The stormwater programs described by the regulated
entities' applications will not reduce the discharge of pollutants to the maximum extent
practicable, protect water quality, or satisfy the requirements of the Clean Water Act.
Furthermore, because the permits provide only a recitation of Session Law 2004-
163 and only incorporates via reference the Comprehensive Stormwater Management
Program Report, which includes components of the permit application, the program
report, and any approved modifications, the public cannot comment adequately on the
actual stormwater program to be implemented by this permit. Without having the actual
stormwater program subject to public comment, the public has no means to evaluate
whether the program is sufficient to meet the specific water quality needs of this area.
See Envtl. Def. Ctr., Inc. v. United States EPA, 2003 U.S. App. LEXIS 19073 (91h Cir.
2003) (holding that permits that do not require measures that control pollutants to the
"maximum extent practicable" contravene the public notice requirements of the Clean
Water Act).
Countywide coverage is needed to ensure adequate protection of water quality.
Pitt, Nash and Edgecombe Counties are required to develop a stormwater program for the
Tar -Pamlico stormwater rule. However TSS removal is not required under the Tar -Pam
rule and BMP designs to address stormwater quantity are inadequate. The Tar -Pam
stormwater rule states, "At a minimum the new development shall not result in a net
increase in peak flow leaving the site from pre -development conditions for the 1-year, 24-
hour storm event" 15A NCAC 02B.0258c(C). Therefore, the Tar -Pam rule requires the
first flush (the first inch of rainfall) to be treated and detained for 2-5 days. While you get
a peak flow that is no greater than pre -construction peak glow, this peak flow occurs for a
much longer duration than pre -construction conditions. Phase I1 requires the BMP's to
store the difference in volume from pre and post -construction of the 1-yr, 24-hour storm
event, which goes further to address the quantity issue.
II. Specific Comments
The federal rules require municipalities to reduce the discharge of pollutants to
the maximum extent practicable ("MEP"), to protect water quality, and to satisfy the
appropriate water quality requirements of the Clean Water Act. 40 C.F.R. § 122.34(a)
2
(2004). The federal rules also specifically require post -construction measures to prevent
or minimize water quality impacts and "to attempt to maintain pre -development runoff
conditions." 40 C.F.R. § 122.34 (b)(5)(i),(iii) (2004). As discussed below, the Rocky
Mount and Greenville NPDES permits fail to meet these federal standards.
A. Rocky Mount NPDES draft permit
Currently, Rocky Mount and Nash County are responsible for a WS-IV
stormwater and the Tar -Pam stormwater programs. Stormwater BMP's for the WS-IV
program are triggered with a sediment and erosion control plan for high -density
development with a built upon area ("BUA") of 24%. Under the Tar -Pam rule, BMP's
are triggered at approximately I 1 % BUA for all new development to comply with
phosphorus requirements. Under the Swift Creek Outstanding Resource Water ("ORW")
stormwater program (within Nash County), BMP's are triggered at 12% BUA and must
reduce TSS by 85%. However, the BMP's are designed for the I-yr, 24-hour storm
whereas the discharge rate shall be no larger than the pre -development discharge rate and
the draw -down is from 2-5 days (as in the Tar -Pam rule & WS-IV rule). The Phase 11
post -construction requirements also required a removal of TSS by 85%. The difference
lies in the stormwater quantity issue, whereas under Phase 11, new development must
implement BMP's that store the difference in volume from pre and post -construction of
the 1-yr, 24-hour storm. However, BMP's are not triggered until you reach it BUA or
24%. The Tar -Pam rule does not adequately address stormwater quantity issues, in that
you may have a pre -construction peak flow for a much longer duration than pre -
construction conditions. This will lead to increased physical deterioration of the streams
and ultimately lead to more erosion and sedimentation problems.
Where does one stormwater program begin and the other end? Rocky Mount and
the unincorporated parts located in Nash County are deemed compliant with the Phase 11
post -construction stormwater rules due to the existing Tar -Pam stormwater program. Is
this also true with WS-IV and Swift Creek ORW requirements? Or does Nash County
now have to implement and run four stormwater programs (Phase II, WS-IV, ORW, and
Tar -Pam)?
Furthermore, Stoney Creek is on the 303(d) list for impaired waters for sediments
based on biological impairment. The 2004 Tar -Pamlico River Basinwide Water Quality
Plan states, "the cause of the depressed bioclassification is likely habitat degradation, as
there was little riparian area and moderate to severe bank erosion." NC Department of
Natural Resources, Tar-Pandico River Basinwide Water Quality Plan, 109 (2004).
Cokey Swamp, located in sub -basin 03 is currently impaired and will be on the 303(d) list
in 2006. The Basinwide plan states, "Habitat degradation, as well as high conductivity,
was noted... Tributaries to this segment drain urban areas in southern Rocky Mount. The
downstream extent of the impaired biological community is not known." The plan
continues, "DWQ will work with the town of Rocky Mount in developing stormwater
programs that will reduce future and current impacts to streams in this watershed." There
are clear indicators that stormwater runoff from urban areas of Rocky Mount is degrading
3
local waterways and that the existing stormwater programs are insufficient to protect
water quality and do not control discharges to the maximum extent practicable.
B. Greenville NPDES Draft Permit
Currently the city of Greenville is responsible for the Tar -Pam and Neuse
stormwater rules and Phase II regulations. Pitt County is responsible for Phase It, Tar -
Pam and Neuse rules, and WS-IV rules.
Prior to Phase 1I stormwater requirements, the City of Greenville required BMP's
to be designed for the 2,5, and 10-year, 24-hour storms. The city recognized that BMP
design for the I-yr, 24-hour storm was inadequate to protect against localized flooding
and to protect water quality. The city has now weakened its ordinance to comply with the
Phase 11 and Tar -Pamlico stormwater regulations. However, the city's staff recognizes
the problem Greenville will face if the ordinance is not amended back to its original
requirements and will work to have the stricter regulations reinstated.
Green Mill Run, whose watershed lies within the City of Greenville, is an
impaired waterway. DWQ does not sample this stream, but the Ecosystem Enhancement
Program has a planned project within this watershed for stream and wetlands restoration.
Green Mill Run is a typical urban stream, with characteristic bank erosion, habitat
degradation due to sediment, and an altered hydrograph resulting in increased frequency
of flooding and peak volumes. Parker Creek, located in the northern section of Greenville
also show signs of impairment, although DWQ did not rate this stream in the 2004
Basinwide Plan. The plan stated, "Parker Creek drains parts of northern Greenville and
had a low habitat score with high conductivity noted at site )~-1. There were also elevated
numbers of tolerant macroinvertebrate species, indicating water quality impacts." The
2003 Basinwide Assessment Report states "the stream had the lowest rated habitat of any
stream in the basin in 2002 (habitat score = 39)." NC Department of Natural Resources,
Tar -Pamlico River Basinwide Water Quality Plan (2004). Stormwater is clearly causing
impairments in these two streams and the existing stormwater programs are failing to
protect water quality or control pollutant discharges to the maximum extent practicable.
111. Endangered Species Concerns
Where water quality protection and maintenance of existing and anticipated uses
is not being achieved, more stringent stormwater measures must be required. Existing
uses include federally listed endangered species. As explained below, the draft permit for
Rocky Mount does not adequately protect the existing uses as endangered mussel habitat.
A. The areas subject to stormwater limitations affects waters that provide habitat to
federally -listed aquatic species that would be adversely affected by stormwater.
The area subject to stormwater limitations affect waters that provide habitat to
two federally -listed endangered aquatic species —the dwarf wedge mussel (Alasmidonta
4
heterodon) and the Tar River spinymussel (Elliptio stein.stan.sana). The dwarf wedge
mussel is known to exist in Stoney Creek and Swift Creek, which are both receiving
waters for stormwater runoff from Rocky Mount. One of the last remaining populations
of the Tar River spiny mussel exists in the Tar -Pamlico watershed and is susceptible to
stormwater runoff from Rocky Mount.
Dwarl' Wedge Mussel
The dwarf wedge mussel was listed as endangered on March 14, 1990. 55 Fed.
Reg. 9447 (March 14, 1990) (attached as Exhibit 1). In listing the dwarf wedge mussel,
the United States Fish and Wildlife Service "USFWS" concludes:
The dwarf wedge mussel was once widely distributed in river systems of
the Atlantic slope from New Brunswick, Canada, south to the Neuse River
system in North Carolina. It was recorded from 70 localities in 15
drainages in I I states and one Canadian province. River systems
historically inhabited by this species included: the Petitcodiac River
system in New Brunswick; the Taunton River, Agawam River, Merimac
River, Connecticut River and Quinnipiac River systems in New England;
the Hackensack River, Delaware River, and Susquehanna River systems in
the Middle Atlantic states: the Choptank River, Rappahannock River,
James River, Tar River and Neuse River systems in the Southeast. Based
on The Nature Conservancy's rangewide status survey and other recent
survey data, A. heterodon is now thought to be extirpated from all but ten
small sites in five drainages in four states...
The disappearance of the dwarf wedge mussel from most of its historic
sites can best be explained by agricultural, domestic, and industrial
pollution of its aquatic habitat. Mussels are known to be sensitive to
[.many elements]. Pesticides, chlorine, excessive nutrients, and ,silt
carried by runoff also present a threat to this species.
Id. at 9449 (emphasis added) (for more information on the dwarf wedge mussel, see
Exhibit 2). The Stoney Creek and Swift Creek watersheds in Nash & Edgecombe
Counties, which contain one of the last populations of the dwarf wedge mussel, receive
much of the stormwater runoff from the Town of Rocky Mount. Id.; see also Rocky
Mount Map (attached as Exhibit 3). Because the draft NPDES permit does not contain
adequate measures to protect this endangered mussel population, the stormwater runoff
regulated under the permit will result in adverse impacts to the dwarf wedge mussel.
2. Tar River Spinymussel
In June 1985, the U.S. Fish & Wildlife Service listed the Tar River spinymussel
as an endangered species. 50 Federal Register 26572-2657 (June 27, 1985) (attached as
Exhibit 4). in listing the species, the Service concludes:
5
Results of it recent Service -funded survey of the Tar, Neuse, and Roanoke rivers
indicate that the Tar River spiny mussel (with an estimated total population size
of 100 to 500 individuals) exists only in approximately 12 miles of the Tar River
in Edgecombe County, North Carolina. This represents a significant reduction in
known range, as historic records show the species was once also found both
upstream (Nash County, North Carolina) and downstream (Pitt County, North
Carolina) of its present range.
The Service has carefully assessed the best scientific and commercial information
available regarding the past, present, and future threats faced by this species in
determining to make this rule final. Based on this evaluation, the preferred action
is to list the Tar River spiny mussel as endangered. The mussel's small
population and present restricted range (12 river miles) make it extremely
vulnerable to a single catastrophic event, and its range has greatly contracted
within the immediate past.
Id. at 26574 (emphasis added) (for more information on the Tar River spinymussel, see
Exhibit 5). The Tar -Pamlico watershed contains the only remaining population of the Tar
River spinymussel. The endangered mussel has been extirpated from the Tar River above
Rocky Mount but an extremely small population remains extant downstream of Rock
Mount in the Tar River near Tarboro. The North Carolina Wildlife Resources
Commission ("WRC") now recognizes populations of the Tar River spinymussel in
Franklin, Nash, Halifax, and Edgecombe Counties. The adverse impacts to the Tar River
spinymussel identified by the USFWS Service include erosion, siltation, and reduced
water quality and are associated with stormwater runoff. This population is impacted by
stormwater runoff from Rocky Mount. See NatureServe, Comprehensive Report Species
— Elliptio steinstansana (attached as exhibit). Because the draft NPDES permit does not
contain adequate measures to protect this endangered mussel population, the stormwater
runoff regulated under the permit will result in adverse impacts to the Tar River
spinymussel.
B. Endangered or threatened aquatic species require enhanced protection from
stormwater.
Scientific information and conclusions that formed the basis for listing of critical
habitat for the dwarf wedge mussel establish that the impacts from stormwater runoff
associated with new development are the types of impacts that will appreciably reduce
the likelihood of the survival and recovery of the endangered mussel. The North
Carolina Wildlife Resources Commission ("WRC"), in consultation with the USFWS,
has identified measures that if implemented and enforced would avoid adverse impacts
from stormwater. WRC, Guidance Memorandum to Address and Mitigate Secondary
and Cumulative Impacts to Aquatic and Terrestrial Wildlife Resources and Water Quality
(August 2002) (attached as Exhibit 6). These measures constitute the best scientific
information available on actions to avoid adverse modification of habitat and jeopardy of
the dwarf wedge mussel. DWQ and the permit applicant must assure that these measures
are included in the final NPDES permit.
6
For watersheds that support federally listed species, the WRC recommends that
certain measures be implemented to provide a higher degree of protection. The WRC
encourages the maintenance and establishment of 200 foot native, forested riparian
bttffers on perennial streams and 100 foot forested buffers on intertnittettt streants.
WRC, Guidance Memorandum (August 2002) (emphasis added). These buffer widths are
based on detailed studies that establish the need for wider buffers to protect endangered
aquatic species.' The WRC goes on to say that if forested buffets do not exist, the buffer -
area should be allowed to revegetate naturally to increase its functionality. Id. The WRC
also advocates maintenance of the natural predevelopment hydrograph. In order to do so,
the guidelines recommend that "new developments can build rising traditional designs at
a level of 7%n impen4ousness, or build more densely, using dedicated open space and
other stormwater practices to mimic the hydrograph which would occur at only 7%
imperviousness." Id (emphasis added).
C. The proposed NPDES stormwater permit_fails to provide adequate._ protection_ to
endangered or threatened aquatic species.
The draft NPDES permits for Rocky Mount includes conditions and limitations
that fall well short of the WRC's guidelines. The following table compares —with
emphasis added —the stormwater permit's wholly inadequate requirements with the
WRC's guidelines for the protection of mussel populations.

DWQ must require the more stringent measures recommended by the WRC
within the areas that drain to the Swift Creek watershed, the Tar -Pam watershed, and the
Stoney Creek watershed in order to protect the endangered dwarf wedge mussel and the
endangered Tar River spinymussel. Although a portion of Swift Creek is classified as
ORW and has more stringent stormwater measures in place, the portion of the watershed
which will receive stormwater from Rocky Mount is not protected by the ORW
designation. The draft NPDES permit sets a definition for low -density development in
the Tar -Pamlico Riverbasin at approximately 11% BUA. Low -density developments are
not required to implement engineered stormwater management controls, such as
infiltration systems or detention ponds. Well documented scientific studies have found
that sensitive waters begin to loose uses and sensitive values decay once built upon areas
reach 10 %l.2 For areas with endangered and threatened aquatic species, the studies
suggest that BUA be limited to 7% imperviousness. This can be achieved through the
use of conventional design at a level of 7% imperviousness or using conservation clusters
with higher densities which incorporate dedicated open space and other controls to

preserve the natural hydrograph. In the Chesapeake Bay area of Maryland, these
measures have been implemented with much Success.I DWQ must require the 7% BUA
trigger for all areas of Rocky Mount that drain to Swift Creek, Stoney Creek, and the Tar
River.
DWQ must also require the more stringent buffer requirements in areas that drain
to Swift Creek, Stoney Creek, and the Tar River, The Tar -Pamlico River Basin —
Nutrient Sensitive Waters Management Strategy sets buffer requirements to control for
nutrient problems at 50 feet landward of all perennial and intermittent streams. The
Water Supply Watershed rules for WS-IV waters sets buffer requirements at 30 feet for
low density development and 100 feet for high density development on all perennial and
intermittent streams. Water dependent uses are allowed to invade the buffer area under
certain circumstances. Neither of these buffer requirements are stringent enough to
ensure survival of the dwarf wedge mussel and the Tar River spinymussel. WRC
guidelines recommend 200-foot forested buffers for perennial streams and 1.00-foot
buffers for intermittent streams. DWQ must include these more stringent measures in the
draft permit for areas within the Swift Creek watershed in order to protect the endangered
mussel populations.
D. The NPDE_S permit must include limitations necessary to meet water quality_
standards.
The NPDES permits must satisfy the federal Phase II requirements. The Clean
Water Act prohibits discharges that violate water quality standards. The rules
promulgated pursuant to 33 U.S.C. § 1342 (p) by the United States Environmental
Protection Agency ("EPA") require regulated entities to "develop, implement, and
enforce a stormwater management program designed to reduce the discharge of
pollutants ... to the maximum extent practicable, to protect water quality, and to
satisfy the appropriate requirements of the Clean Water Act." 40 C.F.R. § 122.34 (a)
(emphasis added).
Based upon existing case law, "maximum extent practicable" means to the fullest
degree technologically feasible for protection of water quality, except where costs are
wholly disproportionate to the potential benefits. See Haeuser v. Department of Law, 97
F.3d 1152, 1 155 (91h Cir. 1996) ("practicable" has been defined as "capable of being
done: feasible"); Rybachek v, United States E.P.A., 904 F.2d 1276, 1289 (9" Cir. 1990)
(EPA must select best level of technology unless costs are "wholly disproportionate" to
the benefits); Assn of Pac. Fisheries v. United States E.P.A., 615 F.2d 794, 805 (91' Cir.
1980). In the stormwater context, these stringent definitions of the term "practicable" are
further narrowed by the use of "maximum," clearly indicating that the measures to be
required must be more protective than standard practice, or than ordinary measures,
where those measures are failing to protect water quality. Such a definition would also
comport with the recent Ninth Circuit decision interpreting Phase II program
requirements. The court there suggested that the "maximum extent practicable" standard

Design Strategies (1999) (attached as Exhibit 9).

may require more of permittees than mere compliance with water quality standards or
numeric effluent limitations designed to meet such standards. Envtl. Def. Ctr., Inc. v.
United States EPA, 319 F.3d 398, 425-26 (9`t' Cir. 2003) (noting that although general
permits will explicitly require compliance with numeric effluent limitations designed to
ensure compliance with water quality standards, additional review of permittees' notices
of intent is required to ensure that permittecs have also designed programs that do in fact
reduce their stormwater pollution to the maximum extent practicable).
Furthermore, because the stormwater management program is regulated through a
National Pollutant Discharge Elimination System ("NPDES") permit other requirements
apply. "Since 1973, EPA regulations have provided that an NPDES permit shall not be
issued 'when the imposition of conditions cannot ensure compliance with the applicable
water quality requirements of all affected States.' n 10 40 C.F.R. § 122.4(d) (1991); see
also 38 Fed. Reg. 13533 (1973); 40 C.F.R. § 122.44(d) (1991); Arkansas v. Oklahoma,
503 U.S. 91, 105 (1992). Federal and North Carolina law require that NPDES permits
ensure compliance with water quality standards. NPDES regulations issued under the
Clean Water Act "specifically require that each NPDES permit contain `any
requirements ... necessary to: (1) achieve water quality standards established under
Section 303 of the Act.' 40 C.F.R. § 122.44(d)(1). Thus any permit that fails to contain
conditions necessary to achieve water quality standards violates both the Act and 40
C.F.R. § 122.44(d)(1)." Champion Intl Corp. v. United States EPA, 648 F. Supp, 1390,
1395 (D.N.C. 1986) (vacated caul reman(led for clifferent reasons by 850 F.2d 182, 186
(4th Cir. 1988).4
North Carolina law prohibits the discharge of waste to waters of the state in
violation of water quality standards. N.C. Gen. Stat. § 143-215.1(a)(6). Permitted
stormwater discharges (direct or indirect) must not result in "water pollution" or
"alteration of the ... biological ... integrity of waters of the state." N.C. Gen. Slat.
143-215.1(a)(11) - 213(19). The FMC's permitting regulations place the burden on an
NPDES permit applicant to demonstrate a proposed system will meet water quality
standards. North Carolina NPDES permitting regulations state:
The permit applicant has the burden of providing sufficient evidence to
reasonably ensure that the proposed system will comply with all
applicable water quality standards and requirements. No permit may be
issued when the imposition of conditions cannot reasonably ensure
4 "1'he Preamble to EPA's stormwater permitting regulations describe the circumstances in which
stormwater permits must comply with water quality standards:
...small MS4 permittees should modify their programs if and when available information
indicates that water quality concentrations warrant greater attention or prescriptiveness in
specific components ofthe municipal program. if the program is inadequate to protect
water quality, including water quality standards, then the permit will need to be modified
to include any more stringent limitations necessary to protect water quality.
64 Fed. Reg. 68753.
compliance with applicable water quality standards and regulations of all
effected states.
15A N.C.A.C. 2H.01 12(c),
E. North Carolina water duality standards require protection and maintenance of
threatened or endangered aquatic species.
Water quality standards applicable to all waters identify "best usage of waters" to
include "maintenance of biological integrity" and further state "[tlhe waters shall be
suitable for aquatic life propagation and maintenance of biological integrity..., sources of
water pollution which preclude any of these uses on either a short-term or long-term basis
shall be considered to be violating a water quality standard." 15A N.C.A.C. 213.021 1(1),
(2). "Biological integrity means the ability of an aquatic ecosystem to support and
maintain a balanced and indigenous community of organisms having species
composition, diversity, population densities and functional organization similar to that of
reference conditions." 15A N.C.A.C. 2B.0200(11). Loss of endangered or threatened
aquatic species, often the most sensitive and vulnerable organisms in an aquatic
ecosystem, contravenes the requirement of water quality standards that the biological
integrity of all waters must be maintained.
North Carolina's antidegradation policy also requires that "existing uses" of all
waters be maintained. 15A N.C.A.C. 2B.0201(b). "Existing uses mean uses actually
attained in the water body, in a significant and not incidental manner, on or after
November 28, 1975, whether or not they are included in the water quality standards..."
15A N.C.A.C. 2B.0200(30). North Carolina's water quality regulations recognize that a
use of a water may include providing habitat for endangered or threatened species:
"Certain waters provide habitat for federally -listed aquatic animal species that are listed
as threatened or endangered by the U.S. Fish & Wildlife Service or National Marine
Fisheries Service under the provisions of the Endangered Species Act, 16 U.S.C. 1531-
1544 and subsequent modifications. Maintenance and recovery of the water quality
conditions required to sustain and recover federally -listed threatened and endangered
aquatic animal species contributes to the support of maintenance of a balanced and
indigenous community of aquatic organisms and thereby protects the biological integrity
of the waters." 5 15A N.C.A.C. 2B.0110
F. Issuance of stormwater permits without adequate protection for federal) -listed
endangered or threatened species violates the Endangered Species Act.
Under Section 9 of the Endangered Species Act, it is "unlawful for any person" to
"take any [endangered] species within the United States...." 16 U.S.C. § 1538(a)(1)(B).
' 15A N.C.A.C. 28.0110 directs the Division of Water Quality to develop site -specific management
strategies under the provisions of 15A N.C.A.C. 213.0225 (Outstanding Resource Waters) or 15A N.C.A.C.
2B.0227 (Water Quality Management Plans) to protect the endangered or threatened aquatic species in
these waters. Although the rule was adopted in August 2000, the Division has yet to propose or designate
any waters under these provisions.
12
It is also "unlawful for any person" to "attempt to commit, solicit another to commit, or
cause to be cointnitte(f' a taking of any endangered species within the United States. 16
U.S.C. § 1538(g) (emphasis added). The term "person" is defined to include "any
officer, employee, agent, department, or instrumentality of the Federal Government, [or]
of any State..." and thus includes DWQ. 16 U.S.C. § 1532(13). "Take" under the Act
includes any "harm" to an endangered species and specifically includes habitat
degradation.' Section 9 prohibits not only the actions of those who directly exact the
taking of endangered species, "but also bans those acts of a third party that bring abOUt
the acts exacting a taking." Strahan v. Coxe, t27 F.3d 155, 163 (1st Or. 1997). In
Strahan, the State of Massachusetts was found to have exacted .a taking of endangered
Northern Right Whales through its licensing and permitting of certain fishing practices
that exacted a taking of the species.7 In Loggerhead Turtle v. County Council of Volusia
County, a federal district court in Florida held that the Volusia County government
caused takings of endangered sea turtles through its authorization of vehicular beach
access during turtle mating season. 896 F. Supp.1 170, 1 180-1181 (M.D. Fla. 1995). As
currently proposed, the draft permit for Rocky Mount would "cause to be committed" a
taking of the endangered dwarf wedge mussel in violation of federal law.
IV. Summary
The Phase 11 requirement that triggers BMP implementation at 24%n BUA is
completely inadequate and will not protect water quality. Well documented scientific
studies have found that sensitive waters begin to lose uses and sensitive values decay
once built upon areas reach 10 percent.8 The Tar -Pam rule triggers implementation of
BMP's as 1 1% BUA, which PTRF agrees is adequate for unimpaired streams, and
waterways that do not have endangered or threatened aquatic species present. We further
understand that as the BUA increases so do the number of BMP's needed to comply with
nutrient reduction requirements. However, we continue to be concerned about several
issues:
No stormwater program looks at downstream effects, this must be addressed

■ The Tar -Pam rule does not require removal of 85% of TSS. For example, grass
swales comply with Tar -Pam rule to address N and P reductions but do not reach an
85% reduction of TSS.
■ BMPs designed for the I-yr, 24-hour storm event is inadequate in urban areas. The
City of Greenville wishes to strengthen their stormwater ordinance to require 2,5, or
10-year designs, because they recognize that the current requirements are insufficient
to protect against flooding and protect water quality.
■ Without a comprehensive or watershed program, water quality will not be protected.
■ In Rocky Mount and Nash County's jurisdiction, this NPDES permit applies, as well
as ORW for Swift Creek, Tar -Pamlico Stormwater rule, and WS-IV. In Greenville
and Pitt County's jurisdiction, the NPDES permit, Tar -Pamlico Stormwater rule,
Neuse Stormwater rule, and WS-IV all apply. This makes it extremely difficult to
implement and to enforce.
In Rocky Mount and Greenville's jurisdiction, Phase II is not necessarily the less
stringent stormwater program. For example, Phase 11 may impose a more stringent
requirement of treating the difference in pre- and post -development runoff for one
year, 24 hour storm (as opposed to just the first inch of runoff).
In Rocky Mount and Greenville's jurisdiction, Phase II requires an 85% reduction in
TSS, whereas the Tar -Pam rule does not. Therefore, the Tar -Pam rule does not ensure
compliance with the Phase I1 program or the Clean Water Act.
An effective stormwater rule would include the following:
i.) Countywide coverage
ii.) Consider downstream effects
iii.) Require implementation of all stormwater BMP's at 10% BUA
iv.) Require removal of TSS
v.) Require BMP's to be designed for the t0-year, 24 hour storm
In the Swift Creek watershed, the implementation of WRC's guidelines to protect
endangered mussels is essential to ensure the survival of the endangered dwarf wedge
mussel.
Because of the significant public interest evidenced by the vital issues raised in
the above comments, we also request a public hearing on the merits of granting these
proposed permits. As you know, N.C. Gen. Stat. § 143-215.1 requires DWQ to consider
all written requests for a public hearing made within thirty days following the notice of
intent to take action on a permit application and to grant such a request if there is
significant public interest. The permits will allow significant degradation of water
quality in the Swift Creek watershed and will have a significant effect on the survival of
the dwarf wedge mussel. DWQ should carefully weigh the effects of its permitting
decision before implementing lax stormwater controls in the habitat of the endangered
14
mussel. Considering the potential effects the permit may have on Swift Creek and more
specifically on the dwarf wedge mussel, we respectfully request that DWQ hold a public
hearing on the proposed NPDES stormwater permit for Wake County. ?
We appreciate the opportunity to provide these comments on the permits. If you
have any questions please feel free to contact us.

MEMORANDUM
TO: Mr. Bradley Bennett, Supervisor
Stormwater Permits Unit
Division of Water Quality
FROM: Maria Tripp, Northeast Coastal Region Coordinator
Habitat Conservation Program
DATE: December 20, 2004
SUBJECT: Draft NPDES Permit to Discharge Stormwater for City of Rocky Mount, Nash County,
North Carolina, NPDES Permit No. NCS000442.
Biologists with the North Carolina Wildlife Resources Commission have reviewed the subject
document and we are familiar with the habitat values of the area. Our comments are provided in
accordance with provisions of the Clean Water Act of 1977 (as amended), the Fish and Wildlife
Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d), and North Carolina General Statutes
(G.S. 113-131 et seq.), and the North Carolina Administrative Code 15A NCAC 10I.0102.
The City of Rocky Mount has applied for a NPDES permit to discharge stormwater
runoff from their municipal separate storm sewer system (MS4) into receiving waters Compass
Creek, Cowlick Creek, Goose Creek, Grape Branch, Hornbeam Branch, Little Cokey_Swamp,
Maple Creek., Stony Creek, Swift Creek, and their tributaries in the Tar River basin. jThere are
records of the Tar spinymussel (Elliptio steinstansana) (FE, SE), Yellow lance (Elliptio
' r lanceolate) (FSC, SE), Atlantic pigtoe (Fusconaia masoni) (FSC, SE), Yellow lampmussel
(Lampsilis cariosa) (FSC, SE), Triangle floater (Alasmidonta undulata) (ST), Creeper (Strophitus
undulatus) (ST), Eastern lampmussel (Lampsilis radiata) (ST), Roanoke slabshell (Elliptio
roanokensis), (ST), Notched rainbow (Villosa_constricta) (SSC), and Carolina madtom_(Noturus
furiosus) (FSC, SSR) within the waters of Swift Creek. Stony Creek is on the State's 303(d) list
due to impaired biological integrity. The potential-stressors are unidentified.
Although the Phase II stormwater rules represent an appropriate baseline for proactively
addressing stormwater issues, we believe additional, more protective measures are appropriate and should
be required to preserve the existing uses and ecological integrity of North Carolina waters over the long-
term, k ' In wagers where federal threatened and endangered species are known to occur, the following
additional measures should be incorporated as permit conditions.

I. Permits for new developments exceeding 6% imperviousness shall be required to include stormwater
controls designed to replicate and maintain the hydrographic condition at the site prior to the change
in landscape and at a minimum include provisions that satisfy WS II-HQW minimum standards
(WSII-HQW waters as precedent; Schueler 1994; Arnold and Gibbons 1996; Doll et al. 2000; Mallin
et al. 2000; May and Horner 2000; Stewart et al. 2000).
2. Infiltration practices (e.g., reduced road widths, rain gardens, parking lot bioretention areas, increased
sheet flow instead of ditching, and disconnect impervious areas) to maintain predevelopment
hydrographic conditions shall be emphasized over detention ponds. Condition information should
include the base flow for low flow conditions.
A 200-foot native; forested buffer on perennial streams and a 100-foot forested buffer on intermittent
streams, or the full extent of the 100-year floodplain, shall be required for new developments. If
wooded buffers do not exist, then these areas shall be revegetated or allowed to naturally revegetate
(so long as the area is pervious) to increase the functionality of a forested buffer. (Knutson and Naef
1997, and references therein; 200-foot buffers on Randleman Lake; 200-foot buffers associated with
protection of aquatic endangered species habitats required for Buckhorn Reservoir Expansion Project
in 1995 — City of Wilson).
4. Delineation of streams should be conducted for the municipal service area according to U. S. Arm% -
Corps of Engineers (USACOE) or N. C. Division of Water Quality (NCDWQ) methodology, This
information can be found at htt ://h2o.enr.state.nc.ushigwetlands/strmfrm.html (accessed December
2004), Stream delineation should occur prior to site clearing activities including tree removal.
5. Commercial or residential development within the 100-year FEMA floodplain and jurisdictional
water floodplains should be prohibited and floodplains should be protected as undisturbed forested
areas.
Grassed swales shall be used in place of curb and gutter for new developments, except in areas with
>5% slope. Check dams, level spreaders, and other associated best management practices shall be
used to minimize the effect of stormwater runoff entering the riparian buffer areas. In areas where
slopes exceed 5%, stormwater collected in piped conveyance systems shall be directed away from
surface waters and best management practices shall be employed at both the intake and the outlet
areas.
7. Direct discharges of stormwater to streams should not be allowed. Effective energy dissipation at the
pipe outlet shall be accomplished to prevent scour of the stream channel and buffer. The ditching or
piping of stormwater except when used in combination with grassed swales, level spreaders and
check dams shall not be allowed in the riparian buffer. At no time should any mandated vegetated
buffer zone be used for these engineered devices.
8. Sewer lines, water lines, and other utility infrastructure should be kept out of riparian buffer areas
(Knutson and Naef 1997; and references therein). Where practicable, utilities should follow the
contours along the edge of floodplains. All utility crossings should be kept to a minimum and the
directional bore (installation of utilities beneath the riverbed, avoiding impacts to the stream and
buffer) stream crossing method should be used for utility crossings wherever practicable. A
minimum I00-200 feet setback on all streams, lakes, and wetlands should be maintained. Pesticides
should not be used for maintenance of rights -of -way within 200 feet of perennial streams and 100 feet
of intermittent streams, or within floodplains and wetlands associated with these streams.
NPDES Permit No. NCS000442 Page 3 December 20, 2004
City of Rocky Mourd
9. Local governments shall encourage and offer incentives for new developments; as part of the
subdivision review process, to use low impact development technique for stormwater control (Low
Impact Development; EPA Document # 841— B-00-002 and 84 1 -B-00-003), and reduce impediments
to implementing the plan. Proposed projects that are subject to NCEPA review shall identify as a part
of the subdivision review process anticipated impervious surface amounts prior to plat approval.
10. Municipalities should incorporate the elements listed below into their erosion and sediment control
plans (see Brown and Caraco 2000 for additional information).
a) Minimize clearing and grading.
b) Protect waterways by preventing clearing adjacent to waterways, and stabilize drainage ways.
c) Phase construction for larger construction sites (>25 acres).
d) Stabilize soils as rapidly as possible (<2 weeks).
e) Protect steep slopes, and avoid clearing or grading existing steep slopes as much as possible.
f) Establish appropriate perimeter controls.
g) Employ advanced settling devices.
h) Implement a certified contractors program.
i) Perform regular inspection of erosion control measures, and sediment control devices.
11. In addition to the items listed above, locally enforced stringent erosion and sedimentation control
requirements shall be developed and implemented for all construction. The development of these
requirements shall be fully coordinated with the state and federal agencies involved in aquatic
endangered species protection. These measures shall be state -of -the -science and significantly exceed
state minimum requirements for sediment and erosion control. Local ordinances shall be developed
to prevent agricultural or forestry exemptions from turning into development opportunities.
12. Developers and builders, including land -clearing operators, shall be required to participate in a local
government stormwater and sediment erosion control education program. Certification and bonding
is recommended.
13. Conservation Reserve Program lands and restoration of prior converted wetlands shall be encouraged
to help manage overall stormwater impacts as part of a regional integrated stormwater management
plan.
14. The local government shall solicit assistance and concurrence from resource agencies such as
NCDWQ, N. C. Division of Land Resources, NCWRC, N. C. Natural Heritage Program, and USFWS
during the initial development and assessment of best management practices for stornnwater
management, sediment and erosion control, utility placement, etc.
15. The local government shall provide an environmental check -off list that a developer must complete
before the issuance of development approvals or any land disturbance, including timbering, to ensure
protection of aquatic habitats for threatened and endangered species and that proper state and federal
permits have been obtained. This shall preclude the issuance of any subdivision plan, building, and
utility permits without inclusion of pertinent protective measures. This process shall ensure that land
clearing does not occur without a site plan, including erosion control.
16. A watershed impact evaluation board shall be established to review projects within the service area
with aquatic, endangered species. The board would ensure compliance, preview infrastructure and
development plans, and be eligible to seek funding for conservation initiatives designed to protect and
preserve aquatic, endangered species.

Comments on Draft Permit
Comment 1. Part II, Section C
Language in item c) needs to provide more flexibility. It appears to require establishment of a permanent
standing advisory panel. The City of Rocky Mount, in keeping with past practice, intends to seek feedback on
the annual report and Stormwater Management Plan through the City Council Committee of the Whole meetings.
When specific policy changes or major initiatives dictate a need for additional outreach and/or input, the city will
consider establishment of a stakeholders group tasked with addressing the item of concern. This same
stakeholder process was used when developing the stormwater utility and updates to the stormwater design
manual.
Comment 2: Part II, Section D
Illicit Discharge Schedule needs to be modified as noted to be consistent with the City of Rocky Mounts Tar -
Pamlico Nutrient Management Plan which calls for dry weather screening of 10% of the jurisdiction per year to
start with the identified highest priority area in 2007. (Year 3 assuming approval of permit in early 2005).
Comment 3: Part II, Section E
Erosion control provisions of this permit shall be implemented in accordance with the requirements of the local
program delegation authority granted to the City of Rocky Mount by the Environmental Management
Commission. The City will rely on NCDENR Land Quality Section to administer these provisions within the ETJ.
Comment 4: Part II, Section F
The City of Rocky Mount intends to regulate post development controls in accordance with the provisions of the
Nutrient Management Program and Post -Development ordinance approved by the EMC in September 2004 and
the provisions of the Water Supply Watershed protection ordinance. Items (a), (b) and (d) are already being
implemented under this plan and ordinance.
Comment 5: Part II, Section G
The City is proposing an adjustment to the implementation of this program to more closely coincide with the
implementation schedule for the illicit discharge program and to provide time to fully implement other provisions
of the program.
Comment 6: Part III
The City would like to use the same annual report for compliance with Tar -Pamlico and NPDES and would prefer
that that these reports be submitted at the same relative time.
Comment 7: Part V, Section A
The City is concerned that items 2 and 3 of Part V, Section A could be construed to hold the City liable for an illicit
discharge from facilities not operated by the City.

Comment 8: General Comment
The individual permit issued to Rocky Mount appears to be essentially the same document as the General
Permit except that the implementation schedule is included as and integral part of City's permit. If the
implementation schedule for each element were to be referenced as the stormwater management plan rather
than within the permit it would appear that the City would be covered under a General Permit subject to General
Permit fees

Subject: NPDES Phase II Stormwater Program
In 1990 the U.S. Environmental Protection Agency's (EPA) Phase I stormwater program was promulgated under the
Clean Water Act. Phase I relies on National Pollutant discharge Elimination System (NPDES) permit coverage to
address stormwater runoff from: (1) "medium" and "large" municipal separate storm sewer systems (MS4s) generally
serving populations of 100,000 or greater, (2) construction activity disturbing 5 acres of land or greater, and (3) ten
categories of industrial activity. The NPDES Stormwater Phase 1I Final Rule was promulgated in December 1999 and is
the next step in EPA's effort to preserve, protect, and improve the Nation's water resources from polluted storm water
runoff. The Phase II program expands the Phase I program by requiring additional operators of MS4s in urbanized areas
and operators of smal l construction sites, through the use of NPDES permits, to implement programs and practices to
control stormwater runoff. Phase II is intended to further reduce adverse impacts to water quality and aquatic habitat by
instituting the use of controls on the unregulated sources of stormwater discharges that have the greatest likelihood of
causing continued environmental degradation.
The NPDES Stormwater Phase It Final Rule requires nationwide coverage of all operators of small MS4s that are
located within the boundaries of a Bureau of the Census defined "urbanized area" based on the latest decennial Census.
We are writing to you to remind you that the City of Rocky Mount has been identified as being located within a census
designated urbanized area in both the 1990 and 2000 decennial census. As a regulated community, you are required to
develop a stormwater management program and apply for stormwater permit coverage, if you own and operate a small
MS4 or file a certification that the City of Rocky Mount does not own or operate a small MS4. The deadline for
submitting your application package or non -ownership certification is March 10, 2003. Application and certification
documents, as well as additional information on the NPDES stormwater program, are available for download at our web
site . Our web address is http://h2o.enr.state.ne.us/su/stormwater.hIm1. You may also contact us for hard copies of the
