RE: [External] FW: Stormwater Question
Wade,
It sounds like tier one investigations are already pointing to a background influence. If a second exceedance for either of
these parameters occurs, I would recommend taking the alternative route of contacting the regional office (see 4.
below) so they can work with you on relieving the obligation to monitor monthly, if the inspector concurs it is
appropriate. As far as tier one for this occurrence, recording the sampling efforts and possible external influence that
was identified is a good start and appropriate response to record in this site's SPPP. Also include a record of whether
on -site problems were ruled out. For future tier one responses, the facility should at least record potential issues on -site
were not identified as a cause.
Permir No. NCG030000
TierTwo
If: The first valid sampling results from two consecutive monitoring periods (omitting periods %vith no discharge)
are above the benchmark values, or outside of the benchmark range, far any specific parameter at a specific
discharge outfall;
Then: The permitter shall:
L. Repeat all the required actions outlined alcove in Tier one.
2. Immediately institute monthly monitoring and reporting for all n= The permitter shall conduct
monthly monitoring at every outfall where a sampling result exceeded the benchmark value for two
consecutive samples. Monthly (analytical and qualitative) monitoring shall continue until three
consecutive sample results are below the benchmark values or within benchmark range.
3, if no discharge occurs during the sampling period, the permittee is required to submit a monthly
monitoring report indicating "No Flow' to comply with reporting requirements.
4. Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances, exercise the
option of contacting the DEMLR Regional Engineer as provided below in Tier Three. The Regional Engineer
may direct the response actions on the part of the permittee as provided in Tier Three, including reduced or
additional sampling parameters or frequency.
G. Maintain a record of the Tier Two response in the SPPP.
& Continue Tier Two response obligations throughout the permit renewal process.
I hope this helps answer your questions.

Hey Bethany,
I have some questions in regards to results of a recent stormwater analytical monitoring for the Robert Bosch Tool facility,
located on 1980 Indian Creek Road in Lincolnton.
This facility just recently submitted a NOI for coverage under the NCG03 General Permit. Their first analytical monitoring
sampling indicates that pH was below 6.00 for three of the four outfalls. Upon conducting an inspection and investigation
for these exceedances, we found that pH was below 6.00 even on the neighboring property which is upstream of the
Bosch facility outfalls. In addition to pH, copper was also exceeded, and copper was also found in exceedance upstream
on the neighboring property.
Was wondering how we should proceed with the TIER One investigation? Could this be contributed to natural
background? In the future if we find the same, do we still need to complete the TIER One.
Your response to this issue is greatly appreciated. I can also be reached on mobile below if you have any questions.
Best regards,

Good Morning Matt,
I am providing assistance to the Robert Bosch Tool, Lincolnton facility with their recent storm water sampling and would
like to discuss the sampling results with you. Based on their Analytical Monitoring sampling conducted on 12/17/19, the
results indicate that pH was below 6.00 for three of the four outfalls. Upon conducting an inspection and investigation for
these exceedances, we found that the pH was low even on the neighboring property which is upstream of Lincolnton's
outfalls.
Was wondering how we should proceed with the TIER One investigation? Could this be contributed to natural
background? Your response to this issue is greatly appreciated. I can also be reached on mobile below.
