Enclosed please find analytical sample results from stormwater sampling conducted at outfall SW001 and SWO03 on
October 14, 2014. The representative storm event measured a total of 2.41 inches but it was not enough to produce
any flow from outfall SW-002.
If there are any questions regarding this request, please contact Shannon Langley at [phone] or
[e-mail].
Sincerely,
Garry A. Whisnant

Asheville Steam Plant
Stormwater Monitoring- October 2014
Stormwater samples were collected from two Asheville Steam Plant stormwater outfalls (see attached table)
during a representative storm event on October 14, 2014 measuring 2.41 inches. This stone event did not
produce any flow from outfall SW-002. Samples were collected directly into properly preserved bottles and
shipped on ice to Duke Energy's analytical laboratory in Huntersville, NC.
Analytical parameters for analysis were: TSS, TDS, Oil &Grease, Cl, SO4, F, COD, Al, As, B, Ba, Ca, Cd,
Cu, Cr, Fe, Mn, Mo, Mg, Ni, Pb, Sb, Se, Tl, Zn, Hardness and Hg. Storage and preservation techniques of
the samples after collection, and prior to analyses, were followed according to Appendix A.
Analyses were conducted by Duke Energy's Huntersville analytical laboratory (NC Wastewater Certification
#248) and Pace Analytical Laboratories (NC Wastewater Certification # 12). Laboratory analytical methods
used for each parameter are provided in Table 1 and analytical results are presented in Appendix B.

°Guidance applies to samples to be analyzed by GC,LC, or GUMS for specific compounds.
°If the sample is not adjusted to pH 2, then the sample must be analyzed within seven days of sampling.
