Dear (4Is Knight:

November 11, 2016
The analytical results of a stormwater sample collected from Outfall-001 on September 29, 2016 contained a fecal
coliform (FC) concentration of (2,430 colonies per 100 ml) which is above the benchmark (1,000 colonies per 100
ml) outlined in NCG120000 (see attached SWU-248 form). The benchmark exceedance is believed to not be
attributed to leachate rather originatin5 from wildlife excrement. A voluntary supplemental raw leachate sample
collected on November 4, 2016 in support of this ASD contained low levels (49 CFU/100 ml) of FC. Since
analvtical results indicate FC was considerably lower in raw leachate and wildlife excrement has been observed
throughout the drainage area it is reasonable to assume the source of FC as detected in Outfall-00I is not attributed
to a release of leachate. Concentrations of FC in raw leachate samples at several other facilities have also been
consistently lower relative to stormwater outfall samples and the benchmark.
A full Tier One response for this FC exceedance at Outfall-001 can/will not be prepared at this time since the
suspected source of FC is likely not attributed to landfill activities and controls/improvements to mitigate FC levels
at a landfill are realistically impractical. The facility plans to continue following permit conditions including semi-
annual analytical/qualitative monitoring. In the future additional raw leachate samples may also be tested for
stormwater sample comparison purposes. If the NCDEQ does not accept this alternative source demonstration in
lieu of a Tier One response please provide us a list of acceptable FC control measures or case studies which have
been proven effective in a landfill setting. If you have any questions or concerns regarding this project please
contact me by phone at [phone] or by email at [e-mail].
