Re: Stormwater NPDES Permit Alternative Source Demonstration for Fecal Coliform at SDO-1
Cleveland Coun Land 1
Permit No.NN O -0072
Permit Period Benchmark Exceeded:Year 4 Period 1
Dear Mr.Khan:
The analytical results of a stormwater sample SDO-1 collected on June 15,2016 indicated a concentration of fecal
coliform(FC) (>1,200 colonies per 100 ml)which is above the benchmark outlined in NCG120000(1,000 colonies
per 100 ml)(see attached SWU-248 form). The benchmark exceedance is likely not attributed to leachate but rather
originating from wildlife excrement that has been consistently observed in the SDO-1 drainage area. Voluntary
supplemental (not required for compliance purposes) raw leachate samples previously collected from the landfill
leachate collection system has not contained detectable levels(<10 CFU/100 ml) of FC. Since previous analytical
results indicate FC was not detected 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 SDO-1 is not attributed to landfill activities.
Concentrations of FC in raw leachate samples at several other facilities have also been consistently lower in relation
to stormwater outfall samples and the benchmark. /
A full Tier One response for this FC exceedance at SDO-1 can/will not be prepared at this time since the source of
FC as identified in SDO-1 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(919)772-5393 or by email at [e-mail].
Sincerely,

3The total precipitation must be recorded using data from an on-site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
4 See General Permit text,Table 3, identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
Note:Results must be reported in numerical format. For example,do not report Below Detection Limit, BDL,<PQL, Non-detect, ND,or other similar non-
numerical format. When results are below the applicable limits,they must be reported in the format,"<XX me/L",where XX is the numerical value of the
detection limit, reporting limit,etc. in mg/L. Conversely,where fecal coliform results exceed the dilution upper limit, report the result as">XX".
Note: If you report a sample value in excess of the benchmark,you must implement Tier 1, Tier 2, or Tier 3 responses. See General Permit text.
