PLAN OF ACTION (POA) FOR LAGOON SLUDGE REDUCTION
Facility Number: 82-358 County: Sam�:,son
Facility Name: Garland-Petty
Certified Operator Name: Ken Avery Operator#: 26028
Note: A certified Sludge Management Plan may be submitted in lieu of this POA.

c. Sludge Depth to be 1 0 0
Removed for Compliance (ft)
d. Sludge Volume to be
Removed (gallons) 1,267,943 0 0
e. Sludge PAN
(Ibs/1000 gal) NA NA NA
f. Liquid PAN
(Ibs/1000 gal) .06 .05 .12
g. PAN of Sludge (Ibs)
(d x e)/1000 NA NA NA
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 SIB 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 SIB Interagency Group
Guidance Document 1.26.

NARRATIVE: Use this section to describe the method(s) that will be used to lower the sludge depth. If
microbe use is planned, specify the product to be used.
Sludge Management/Operation Plan
Sludge Management Guide
Lagoon evaluation data 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 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 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 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 DWQ.
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.
