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
DWQ 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 NRCS Standard 359 must be achieved within two years of the
original sludge survey indicating non-compliance. If future sludge surveys do not show improvement in
sludge levels, DWQ may require the owner to develop a sludge management plan that meets the
requirements of SB Interagency Group Guidance Document 1.26.

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. I further certify and acknowledge that compliance with regard to sludge accumulation
must be achieved within two years of the original sludge survey indicating non-compliance.

Sludge Management/Operation Plan
Sludge Management Guidance
Lagoon evaluation data developed by NCSU and a review of lagoon management records of several
lagoons showed that the treatment capability of the swine lagoons evaluated in NC was not
significantly adversely affected by sludge accumulations of 50% or more of the planned treatment
volume of the lagoon. Therefore it is felt that it is permissible to allow sludge accumulation into the
planned treatment zone of property 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) with no excess application.
• 5top•pump level Is easily attained with no adverse deposition of sludge into temporary
storage.
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 2.5 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 DWO.
