FROM: Ron Linville, Regional Coordinator POINT SOURCE
Habitat Conservation Program
DATE: April 19, 2007
SUBJECT: Wastewater Treatment Plant (WWTP) Permits — Dan/Roanoke River Basin
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have reviewed
NC Division of Water Quality (DWQ) notices for the proposed issuance of WWTP permits for
potential impacts to fish and wildlife. Biologists with the NCWRC are familiar with habitat
values in the area. The NCWRC is authorized to comment and make recommendations which
relate to the impacts of this permit or project to fish and wildlife pursuant to Clean Water Act of
1977, North Carolina Environmental Policy Act, US National Environmental Policy Act,
Endangered Species Act (16 U. S. C. 1531-1543; 87 Stat 884), the Fish and Wildlife
Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d) and/or Federal License of
Water Resource Project Act (Federal Power Act-16 U.S.C. 791a et seq.) as applicable.
DWQ is in the process of issuing and/or re -issuing National Pollutant Discharge Elimination
System (NPDES) permits for several WWTPs that discharge into the Dan/Roanoke River basin.
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have reviewed
the location of these sites and have determined that additional scrutiny is appropriate for
ammonia, chlorine, and copper. The specific NPDES permits we have reviewed are:
• Cains Way Homeowners Association (NC0075027)
• Horizons Residential Care Center (NC0056791)
• Kobe Wieland Copper Products, Inc. (NC0035173)
• Stokes County Board of Education (NC0044954, NC0044962, NC0087980)
• Town of Danbury (NC0043290)
• Twin Lakes Mobile Home Park (NC0057720)
Chlorine & Ammonia Concerns -
Chlorine is acutely toxic to aquatic organisms and forms secondary compounds that are also
detrimental to aquatic life, especially eggs and juveniles. We also have concerns regarding daily
ammonia concentrations. Freshwater mussels are among the most sensitive aquatic organisms
tested for impacts from ammonia, and ammonia may be a significant limiting factor for unionids

(Augspurger et al:, 2003). Recent research by Augspurger et al. (2003) found that ammonia
concentrations which may be protective of freshwater mussels range from 0.3 to 1.0 mg/L total
ammonia as N at pH 8.
Copper Concerns -
Treated wastewater from Kobe Wieland Copper Products Inc. is discharged to an unnamed
tributary that flows into the lower portion of the Dan River, a Significant Aquatic Resource as
designated by the North Carolina Natural Heritage Program. The Dan River provides diverse
species habitats and harbors several State and Federally listed mussel and fish species, including
the James (River) Spiny Mussel, Pleurobema collina (State Endangered, Federal Endangered).
There are recent records (2001) for the Green floater, Lasmigona subviridis (State Endangered,
Federal Species of Concern) recorded in the NCWRC Aquatics Database. These records are
directly below the confluence of the aforementioned unnamed tributary to the Dan River.
Although the James (River) Spiny Mussel has not been reported in this lower section of the Dan
River, the possibility strongly exists since the Green Floater is a common species associate of the
James (River) Spiny Mussel in the Dan River. The discharge of copper to the unnamed tributary
is an immediate concern for both mussel species. In a 28-day chronic Copper toxicity
experiment, Wang et al. (in press) demonstrated that as little as 12-21 micrograms of copper per
liter of water (0.012-0.021 milligrams/liter) results in an LC-50 (concentration that kills 50% of
the animals in the sample; i.e., Lethal Concentration) for several species of native juvenile
freshwater mussels. This research suggests that mussels are more sensitive to copper pollutants
than other taxa (e.g., fish and microcrustaceans). Monitoring records indicate that on December
31 st, 2006 Kobe Wieland Copper Products Inc. discharged an average of 136 micrograms of
copper per liter of water (0.136 milliliter) from pipe 001 and 380 micrograms of copper
per liter of water (0.380 milligrams/liter) from pipe 003 (data extracted from E.P.A. Envirofacts
Data Warehouse). Those discharge concentrations are well above detrimental levels for juvenile
freshwater mussels according to recent research (Wang et al. in press).
The following recommendations should be evaluated and incorporated into these and other
NPDES permits as appropriate to avoid and reduce potential impacts to fish and wildlife
resources, especially in areas known to support listed and highly sensitive species:
1. Only non -chemical disinfection like ultraviolet or ozone should be permitted and used,
Chlorine should be expressly prohibited from any use (including emergency operations)
at the WWTP. This should provide the additional benefit of removing hazardous
materials from the environment and the workplace.
2: Ammonia limits should be reduced to the maximum extent practicable. Ammonia and
PH monitoring should be required daily. Daily composite sampling may be appropriate.
3. If not already in place, we recommend provision of automatic stand-by power generation
to prevent plant emergencies and upsets caused by power outages.
4. If publicly owned collection systems and treatment works (POTW) become available,
these facilities should be required to connect to the POTW without delay.
5. Kobe Wieland Copper Products, Inc. and any other NPDES permits with copper issues
should have reduced copper limits to avoid potential impacts to aquatic species,
especially where federally listed aquatic species are known within the watershed.
Although other factors may also contribute to aquatic habitat degradation, we believe the above
evaluations and prevention measures are appropriate. Limits should protect aquatic habitats

(water quality) and preclude acute or chronic issues from WWTP point source discharges. We
are especially concerned about maintaining aquatic habitat values in the Dan/Roanoke, River
basin and similar healthy watersheds. These high value habitats are usually undeveloped
watersheds that need proactive management strategies to preclude impairment from development
as well as from point and non -point issues.
Thank you for the opportunity to provide input during the planning stages for this project. If we
can be of further assistance, please contact me at 336-769-9453. Mr. Robert Nichols, Aquatic
Wildlife Diversity Coordinator is very knowledgeable about the Dan/Roanoke basin's listed
aquatic species as well as the diversity of aquatic species present in the watershed. You may
contact Mr. Nichols at 919-786-1789. You may contact Tom Augspurger with the U.S. Fish and
Wildlife Service at 919-856-4520 for additional information concerning toxicity and federally
listed species.
