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 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 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, DWR
may require the owner to develop a sludge management plan that meets the requirements of SB
Interagency Group Guidance Document 1.27.

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.
1) Sludge Management Plan (In accordance with NRCS Standard 359, Sludge Management Guidance): Continue
current lagoon management and monitoring of sludge as long as:
A) the sludge level is less than the stop pump level of the lagoon,
B)nutrient values of the lagoon effluent are within the normal operating range,
C) there is no noticeable increase in lagoon odor,
D)a minimum 2.5 ft deep zone, free of sludge, at the pump intake is maintained, and
E) nutrients applied from lagoon are properly accounted for in the application plan (NUP).
2) Sludge Removal- Within 90 days of not maintaining the items listed in the above sludge management plan, one of
the following options will commence:
A) Mechanical Removal by Pump and Haul - a sludge utilization/application plan will be developed that identifies land in
the vicinity of the lagoon that will allow for the application of the agitated/mixed sludge layer of the lagoon.
Implementation of the plan will commence within another 180 days. Records will be kept of these applications as
required by the permit.
B) Mechanical Removal by Dewatering - sludge will be removed by dredge or lagoon agitator pump then mixed with
polymer and pumped into geotextile tubes (bags) for dewatering, as outlined in the Management Plan of the Distribution
of Animal Residuals Solids Permit, #W00037487. After curing for approximately 6 months solids will be distributed
within 2 years either
i) as a Class A material in accordance with permit #WQ0037487, or
ii) if the solids do not meet Class A standards, in accordance with a sludge utilization/application plan for
land application.
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.
