Thank you for your cooperation in the Division's lagoon waste sampling efforts on April 13, 2018. On that
day seven teams of Division staff sampled 35 farms and a total of 55 waste lagoons. Multiple teams were
necessary to assure that teams followed proper biosecurity protocols to protect your animals. I apologize
for the short notice that was provided to you by our staff. It was our intent to do the sampling as efficiently
and effectively as possible with as little disruption to you and other operators. Staff notified you as soon
as possible once we were comfortable that weather would cooperate and we had staff prepared to complete
the desired sampling on a single day. Complete results of the sampling are available on the NCDA&CS
Agronomic Services Division PALS website and can be accessed there at your convenience.
httpJ/www.ncagr.gov/agronomi/pals/
The Division submitted the samples to the lab on April 13, and the standard waste analysis was performed
the following week. The certified results are available to use for loading rate calculations in you waste
application records. Our staff followed sampling protocol established by NCDA&CS Agronomic Sampling
Folder No. 6, revised April 2014, a copy of which is included with this letter. You may at any time resample
your lagoons to establish updated results if you feel more representative sample is desired for future
application events.
One of the intents of the sampling effort was to look at observed changes in lagoon sampling results in a
relatively short period of time. Our records show that a previous sampling event took place on March 17,
_2018. Results of -the April-13 and-March-la-samplirg-events are shown en -the -following -pages -for each
lagoon sampled on your farm.
The results show a significant difference in the PAN concentrations as well as other macro and micro
nutrients that put into questions the validity of the March I r sampling results. It is unlikely that a lagoon
make-up will change significantly in a month without significant operations event occurring like a lagoon
sludge clean out. Staff also noted a high observed sludge blanket in your lagoon; however, have not yet
obtained records of the last sludge survey to verify visual observation: For these reasons the Division has
deemed the March 1716 sampling results for lagoon NG3 to be invalid until additional information or
explanation can be provided to justify differences in sampling results. More details on the information
requested to validate the March I sampling data is included below.

As a result of initial evaluation of the sampling results the Division will be conducting additional evaluation
of historic data at your farms and at the other farms that were sampled on April 13, 2018. It is necessary to
further investigate the unusual changes in lagoon characteristics between March 17 and April 13, 2018.
To assist in the investigation please provide the following to the Wilmington Regional Office no later than
June 21, 2018.
• Results of the last 2 years of sludge survey, including information on who conducted the survey.
• Records of any sludge removal that occurred between March 17 and April 14, 2018.
• Any operational changes that may have contributed to the lagoon characteristics between March
17 and April 13, 2017.
• Results of any additional lagoon waste analysis for the lagoon in question conducted since March
17, 2018
Please contact the Wilmington Regional Office at [phone] or Christine Lawson at (919) 807- 6354
if -you have fi ther questions. - -- - - - - - - - - -
