Ruth,
Campbell Soup can cease the background pH monitoring as required by our office and continue the sampling as required
by the NPDES permit. As noted in your letter please complete additional sampling when pH values are less than or equal
to 5.0 and information with a Plan of Action . If you have any questions or we can be of further assistance feel free to
contact me or other DWR staff.

Dear Ms. Henson,
Under Campbell Soup Supply Company's NPDES General Permit NCG500000, the site is
required to perform semi-annual sampling. One of these parameters is for pH with a range of
>6.0 and < 9.0 standard units.
Back in April of2011 during a semi-annual sampling event the iiH was below the required
range. Your office required Campbell's to begin collecting background data to show that the
natural pH within the Glitch area is lower than NPDES permit requirements.
Attached is a spreadsheet outlining the monthly sampling that has been performed since 20J 1.
There continue to be a number of data points that are lower than 6.0 which would indicate this
area is slightly acidic. Based on a review of this data, Campbell Soup would like to discontinue
monthly sampling. At any time during future semi-annual sampling events if the pH is below 5.0
Campbell Soup will resample, investigate and evaluate the possible cause of the. lower pH and
continue monthly Monitoring until the pH levels are above 5.0.
Please contact me at 910-844-1654 or by email at Jamie C;ollins(%campbellsoup.com. should you
need additional information.
Sincerely, ,> /,
y V;2e-er. ( ofL C sta!
