Attached is a copy of my most recent Sludge Survey. This survey
shows I currently have ft. of permanent liquid treatment
storage in my animal waste lagoon, which is more than the
required four feet. Based on these findings I request to be exempt
from further sludge surveys for the life of my current permit, or the
number of years you and your office deem adequate.
Thank you for your consideration of this request.

led Pe 4
c. Thickness of the sludge lyeif tankting a direct measuremenwith "core sampler":
F. Lagoon Surface Area (using dimensions at inside top of bank): ,? ,1 / (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, someasurements should be made.)
G. Estimate number of sampling points:
a. Less than 133 acres: Use 8 points
b. Ifmore than 1.33 acres, 2, 2i-iicres x 6 = /',V . , with maximum of24.
(Using sketch and dimensions, develop a uniferfli grid that has the same number of moons as the
estimated number of samplingpoints 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 measurement of distance from liquid surface to top of sludge layer and record it
on the Data Sheet (last row); this must be at least LS ft. when irrigating.
I. At the time of the sludge survey, also measure the distance from the Maximum Liquid Level to the Present
Liquid Level (measure at the lagoon gauge pole): /t de

L. Calculate the distance from the present liquid stance level to. the

O. Record from the Sludge Survey Data Sheet the average thickness of the sludge layer: Y d 3
P. Calculate the thickness of the existing Liquid Treatment Zone (Item N minus Item L): _ 4, 2.0
Q. If Item 0 is greater than Item P, proceed -to the Worksheet for Sludge Volume and Treatment Volume.
If Item 0 is equal to or less than Item P, you do not have to determine volumes.
