PLAN OF ACTION(Poa) FOR HIGH FREEBOARD AT ANIMAL FACILITIES
Facility Number: 82-186 County: Sampson •
Facility Name: Herbert Bowden
Certified Operator Name: Anthony W. Robinson Operator Number: 989092
1. Current liquid level(s)in inches as measured from the current liquid level in the lagoon to the
lowest point on the top of the dam for lagoons without spillways;and from the current liquid level
in the lagoon to the bottom of the spillway for lagoons with spillways.
Lagoon 1 Lagoon 2 Lagoon 3 Lagoon 4 Lagoon 5
Lagoon Name/ID: 1
Spillway(Y or N): N
Level(inches): 17
2. Check all applicable items
Liquid level is within the designed structural freeboard elevations of one or more structures.
Five and 30 day Plans of Action are attached. Hydraulic and agronomic balances are
within acceptable ranges.
X Liquid level is within the 25 year 24 hour storm elevations for one or more structures. A
30 day Plan of Action is attached. Agronomic balance is within acceptable range.
Waste is to be pumped and hauled to off site locations. Volume and PAN content of waste
to be pumped and hauled is reflected in section III tables. Included within this plan is a list
of the proposed sites with related facility numbers, number of acres and receiving crop
information. Contact and secure approval from the DWQ prior to transfer of waste to,a site
not covered in the facility's CAWMP.
Operation will be partially or fully depopulated.
*Attach a complete schedule with corresponding animal units and dates fro depopulation
if animals are to be moved to another permitted facility, provide facility number, lagoon
freeboard levels and herd population for the receiving facility
3. Earliest possible date to begin land application of waste: 6/3/20 Weather permitting.
I hereby certify that I have reviewed the information listed above and included within the
attached Plan of Action,and to the best of my knowledge and ability,the information is
accurate and correct.

x. Crop's remaining PAN balance(fine v from section III)= 803.2 lb. PAN
y. Overall PAN balance(w-x)= -332.3 lb. PAN

Line y must show as a deficit. If line y does not show as a deficit, list course of action here including pump and
haul,depopulation, herd reduction, etc. For pump&haul and herd reduction options,recalculate new PAN
based on new information. If new fields are to be included as an option for lowering lagoon level,add these
fields to the PAN balance table and recalculate the overall PAN balance. If animal waste is to be hauled to
another permitted facility, provide information regarding the herd population and lagoon freeboard levels at the
receiving facility.
