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
Lagoon Name (ID): 1
Spillway (Yes or No): No
Level (inches): 18. 5"
2. Check all applicable items
X 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: as conditions per mi t
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.
Waste will be applied as soon as weather permits.
