PLAN OF ACTION(Poa) FOR HIGH FREEBOARD AT ANIMAL FACILITIES
Facility Number: 82-160 County: Sampson
Facility Name: Darden Farms Nursery
Certified Operator Name: Andy Darden Operator Number: 18370
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 1
'Spillway(Y or N): N N
Level(inches): 17 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: 6/17/2020
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.

IV. FACILITY'S PoA OVERALL HYDRAULIC LOAD TO BE LAND APPLIED PER ACRE
line o = 0.16 inches per acre to be applied within 5 days
PoA(3g.Day)2/21/00

line x
If unable to land apply hydraulic load listed in line y, list course of action here including pump
and haul,depopulation, herd reduction, etc. For pump& haul and herd reduction options,
recalculate new hydraulic load based on new information.
Plan to land apply hydraulic load:
1. Describe moisture conditions of fields? (e.g. Is there water standing in field; does irrigation
equipment mar down in field; "trafficability" across soils; will soils absorb application without runoff, etc.)
fairly wet
2. Date and amount of last rainfall event?
DATE: 06/20/16 AMOUNT: inches
3. Dates of last waste application event per field:
4. Given optimum soil and weather conditions, is irrigation equipment capable of applying the volume in
line"n"at appropriate seasonal (i.e. winter) application rates within 5 days?
yes
5. Irrigation schedule for next 5 days-include daily schedule; proposed application rates and amounts
per irrigation event; changes made in gun sizes, nozzles, "o" rings, operating time, travel speed, etc. to
meet proposed changes in application rates and amounts; and any other information for consideration.
Irrigate daily with 2 reels moving as needed.
