Jackie - I just have a couple of minor comments on these. Thanks for including the nutrient stuff in
these corrections.
• In the cover letter, check the allocations - a couple of them have a period where the comma should
be
• Since we talked, I did some work on the NRCA's allocations and decided to start adding allocations
'as viewed,' to get rid of these rounding errors that keep coming up. So WiLson's new allocation
should be 157,684 + 202 =157,886 lb/yr. Please correct the total in the cover letter and fact sheet
and remove the reference to rounding in the cover letter.
Thanks again for including this in the corrections. And for your patience.

Mr. Brice,
You are correct. The sample type for chloroform and dichlorobromomethane should be
listed as "grab" not "composite". A permit correction with a new effluent page
showing the proper sample type will be forwarded to you next week. Your lab is
authorized to collect samples for chloroform and dichlorobromomethane as grab, pending
receipt of the corrected effluent page.
Thank you,
Jackie Nowell

Dear Ms. Nowell:
This refers to the City of Wilson NPDES permit that became effective December 1,
2008. In Part A. (1) Effluent Limitations and Monitoring Requirements -Final, the
monitoring requirements for Chloroform and Dichlorobromomethane list the sample
type as composite. Generally a grab sample is required for volatile compounds.
Could you confirm that the sample type, composite, in the permit is correct for
these two volatile compounds?
Your help on this is appreciated.
Thanks,
