PLAN OF ACTION (PoA) FOR HIGH FREEBOARD AT ANIMAL FACILITIES M4
Facility Number: _31_ - _871 County:_Duplin
Facility Name:_Earth Right Farms, Inc. — Sow Farm
Certified Operator Name: _Stephen M Williamson Operator #_19128
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.
Structure 1 Structure 2 Structure 3 Structure 4 Structure 5 Structure 6
Lagoon Name/Identifier (ID): _1
Spillway (Yes or No): _No_
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
pumped and hauled is reflected in section III tables. Included within this plan is a list of the
proposed sites with related facility number(s), number acres and receiving crop information.
Contact and secure approval from the Division of Water Quality prior to transfer of waste
to a site not covered in the facility's certified animal waste management plan.
Operation will be partially or fully depopulated.
- attach a complete schedule with corresponding animal units and dates for 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: 6-06-2018
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.

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.
NARRATIVE:
We have received 26.4" of rain since January 1, 2018 with 16.2" coming since April 7 which
combined with changing from winter crops to summer crops and soil condition has made it
difficult to manage the lagoon level. We are working diligently as crops and soil conditions
allow to get the lagoon freeboard back above 19". David Powell with DWR was notified of the
freeboard level being below 19" on June 1, 2018.
