Re: Campbell Soup Spray Irrigation meeting: Permit number WQ0003626
The following are items for discussion during the meeting here in ,Fayetteville on 18 June 2008 with
Campbell, Soup and DWQ. After reviewing the NDAR/NDMR's submitted for the past couple, a number
of the items below reflect thedifferences between what Campbell Soup is reporting verses permit
conditions and operations:
1. Permit language of 4 MGD. Campbell Soup has historically looked at the wastewater flow rate as a
4 MGD 30 day average verses a strict interpretation of 4 MGD maximum limit; not to exceed: After
reviewing the submitted monthly reports back to September 2004 to the present; the 4 MGD limit
was exceeded 5 to 6: times/month on 'average. When looking at the 30 day average ,of the
wastewater flow rates, the 4,,MGD limit was not exceeded. Notrecord exists in the files for NOV's
issued concerning flow rate;
2. After reviewing the same window of records identified in, item #1, a issue that needs` to be
addressed is the exceedence of -the daily field hydraulic capacity of 4.23 MGD. Based on the
application rates identified in the permit (156"/yr, 91"/yr and 51"/yr)and the field acreage for each
field; in 2004 six exceedences occurred, in 2005 twelve exceedances occurred, in 2006 thirteen
exceedences occurred and in 2007'eight exceedences occurred. In other cases there were
application rates that approached the 4.23 MGD hydraulic limit'.and rainfall occurred the day of the
application; but I didn't calculate to see if the hydraulic capacity of the spray fields was exceeded
with rain and wastewater applied;.
3. In relation to the application rate(s)in item #2, in reviewing the NDAR's for the same window of
time; Campbell Soup is reporting only one yearly application rate of 156"/yr when there are three
different application rates (as identified in item #2 above);
4. The application acreage reported on the NDAR is reported as one 400.78 acre field, when there
are nine fields (7 pivot systems and 2 solid set fields with multiple zones, each zone'. having a
distinct acreage per the permit). When calculating the total acreage listed in the current permit,that
Campbell Soup isutilizing, the' total acreage is only 384.64 (the current permit has a incorrect
acreage_ listed for "J" field :per the engineers certification. "J field should be listed with a total- ,
acreage of 50.10 verses 54.00. This will need to be corrected during permit renewal.

5. In reviewing a drawing in the permit file of the center pivots at the facility, there is a discrepancy
between the acreage listed in the current permit for pivots A,C,D,E,F & G verses the calculated
acreage using the radius shown on the drawings. Again, during permit renewal a wetted acreage
determination will need to be done to verify the exact acreage being applied to;
6. Field "J" has two application rates depending on which zone is being applied to. Zones J-1 to J-7 &
J-10 have a rate of 91"/yr and zones J-8, J-9 & J-11 have a application rate of 51"/yr. Campbell is
reporting all application rates at 3"/week (156"/year).
7. Facility modification request concerning the replacement of the existing DAF unit (217K gallon) and
the addition of a new DAF unit (217K) for an increase in' total treatment capacity to 434,000
gallons??
. These items are provided as a outline for the discussion at our meeting on 18 June. If additional
