PLAN OF ACTION (POA) FOR LAGOON SLUDGE REDUC*ft
11 Ro�fonfr� U ,
Facility Number: 51-40 County: Johnston
Facility Name; Dunn Farm
Certified Operator Name: Steven Stewart Operator #: 1002865
"Attach a copy of Lagoon Sludge Survey Form and volume worksheets
Note: A certified Sludge Management Plan may be submitted in lieu of this POA.
Compliance Timeframes:
If the sludge level is equal to or higher than the stop pump level of the lagoon or if the sludge level
results In an elevated waste analysis, a sludge management plan that meets the requirements of SB
Interagency Group Guidance Document 1.26 must be prepared by a technical specialist and submitted to
DWR within 90 days. Work to reduce the sludge level must begin within another 180 days. Compliance
with NRCS Standard 359 must be achieved within two years of the original sludge survey.
If the sludge level is non-compliant but below the stop pump level of the lagoon, a POA must be filed
within 90 days and compliance with MRCS Standard 359 must be achieved within two years of the
ori final sludge survey Indicating non -cam liance. If future sludge surveys do not show improvement in
sludge levels, DWR may require the owner to develop a sludge management plan that meets the
requirements of SB Interagency Group Guidance Document 1.27.

depth. If microbe use Is planned, specify the product to be used.
Sludge ManagemenUDperation Plan
Sludge Management Guide
Lagoon evaluation date developed by NCSU and a review of lagoon management records of several lagoons
showed that treatment capacity of the swine lagoons evaluated In NC was not aignlficantly adversely affected
by sludge accumulations of 50% or mors.of the planned treatment volume of tho lagoon . Therefore It Is felt
that it Is permissible to allow sludge accumulation Into the planned treatment zone of properly monitored and
managed lagoons provided that
• Nutrient values of the lagoon effluent are within the normal operating range.
• There is no noticeable Increase In lagoon odor.
• Nutrients land applied from the lagoon are properly accounted for in the application plan (WUP)
Sludge Management
Sludge in my lagoon will be managed by the following
• Adequately monitor to define sludge volume, location, and rate of accumulation by conducting an
annual sludge survey.
• Maintain a minimum 25 feet deep zone, free of sludge at the pump Intake during Irrigation.
• Position the pump Intake and manage the Irrigation operation such that the material Irrigated is not
more concentrated than the nutrient analysis samples.
• Sufficient monitoring to address concerns that nutrients are not over applied.
• Other items as required by DWtd.
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
