C. Person(s) Taking Measurements Curtis Barwick
D. Date of Measurement 12/16/2021
E_ Methods/Devices Used for Measurement of:
a. Distance from the lagoon liquid surface to the top of the sludge layer.
sonar
b. Distance from the lagoon liquid surface to the bottom (soil) of the lagoon.
pve pipe
c. Thickness of the sludge layer if making a direct measurement with "core sampler"
F. Lagoon Surface Area (using dimensions at inside top of bank): 1.9 (acres)
(Draw a sketch of the lagoon on a separate sheet, list dimensions; and calculate surface area. The lagoon
may have been built different than designed, so measurements should be made.)
G. Estimate number of sampling points:
a. Less than 1.33 acres: Use 8 points
b. If more than 1.33 ac. acres x 6 = 3251 , with maximum of 24.
(Using sketch and dimensions, develop a uniform grid that has the same number of intersections as the
estimated number of sampling points needed. Number the intersection points on the lagoon grid so that data
recorded at each can be easily matched.)
H. Conduct sludge survey and record data on "Sludge Survey Data Sheet" (Appendix 2). Also, at the
location of the pump intake, take measurements of distance from liquid surface to top of sludge
layer and record it on the Data Sheet (last row); this must be at least 2.5 ft. when irrigating.

Level (measure at the lagoon gauge pole):
0.6

L. Calculate the distance from the present liquid surface level to the Minimum Liquid Level
(Item K Minus Item 1, assuming the present liquid level is below the Maximum Liquid Level)
M. Record from the Sludge Survey Data Sheet the distance from the present liquid surface level to the
lagoon bottom (average for all the measurement points)

Appendix 3. Worksheet for sludge volume and treatment volume
Revised August 2008
The average thickness of the sludge layer and the thickness of the existing liquid (sludge -free) treatment zone are determined
from the information on the Lagoon Sludge Survey Form ( Items 0 and P, respectively). In this example, the average sludge
layer thickness is 2.5 feet and the existing liquid treatment zone is 3.5 feet If the lagoon has a designed sludge storage volume,
see notes at end of the workshee#_ The dimensions of the lagoon as measured and the side slope are needed
for calculations of sludge volume and of total treatment volume_ If the lagoon is a standard geometric shape, the sludge
volume and the treatment volume in the lagoon can be estimated by using standard equations. For approximate volumes
of rectangular lagoons with constant side slope, calculate length and width at the midpoint of the layer, and multiply by layer
thickness to calculate layer volume, as shown in the example. For irregular shapes, convert the total surface area to a square
or rectangular shape. For exact volumes for lagoons with constant side slope, the "Prismoidal Equations" niay be used_
Example Your Lagoon
1. Average sludge Layer Thickness (T) 2.5 ft. 4.7 ft.
2. Depth of the lagoon from top of bank to bottom soil surface (D) 11 ft. 11.9 ft.
3. Slope = Horizontal/ vertical side slope (S) 3 1.5
4. Length at the top of inside bank (L) 457 fir 417.1 ft.
5. Width at top inside slope ()Aj 229 ft. 200.0 ft.
6_ Length at midpoint of sludge layer L", = L-2S(D-(T/2)) 398.5 ft. 388.5 ft.
7. Width at midpoint cf sludge layer Wm= W-2S(D-(T/2)) 170.5 ft_ 171.4 ft.
8_ Volume of sludge (Vs) Vs=L,n Wm T 169,860 ft3 312,994 ft3
9. Volume in gallons: Vsg=V*7.5 galift3. 1,273,950 gal. 2,347,456 gal.
10. Thickness of existing liquid tmt. zone (Y) 3.5 ft 3.4 ft
11_ Thickness of total treatment zone (Z) Z= T+Y 6 ft 8.1 ft
12. Length at midpoint of total tmt. zone Lz = L-2(S)(D-(ZJ2) 409 ft_ 393.6 ft.
13. Width at midpoint of total tmt. Zone WZ = W-2(S)(D-(Z/2) 181 ft_ 176.5 ft.
14. Volume of total treatment zone (Vz) Vz = Lz WZZ 444,174 ft3 562,756 e
15. Ratio ( R ) of sludge layer volume to total Treatment Volume
R = VsNz
0.38 0.56
If the ratio R exceeds 0.50, than a sludge Plan of Action may be required. Check with DWQ for information
on filing the Plan of Action.
Note: If the lagoon has a designed sludge storage volume (DSSV), subtract that volume from both the volume
of sludge (Vs) (Item 8) and from the volume of total treatment zone (Vz) (Item 14), and take the ratio.
Then, R = (Vs-DSSV) / (Vz - DSSV)
Example: If DSSV = 85,000 ft3, then R = (169,860 - 85,000) / (447,174 - 85,000) = 84,860 / 362,174 = 0.24.
16. Design sludge storage volume (DSSV) 85,000
17. Ratio (R) of sludge layer volume to treatment volume adjusted
for designed sludge storage volume 0.24 0.56

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 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 5B Interagency Group Guidance Document 1.27.

microbe use is planned, specify the product to be used.
Sludge Management/Operation Nan
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
properly monitored and managed lagoons providing that:
• Nutrient values of the lagoon effluent are within the normal operating range.
• There is no noticeable lagoon odor.
• Nutrients land applied from the lagoon are properly accounted for in the application plan (WUPJ
with no excess application.
• Stop -pump level is easily attained with no adverse deposition of sludge into the temporary
storage
Sludge Management
Sludge in my lagoon will be managed by the fallowing:
• Adequately monitor to define sludge volume, location, size, 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.
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.
