(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 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 2.5 ft. when irrigating.

Appendix 3. Worksheet for sludge volume and treatment Re
The average thickness of the sludge layer and the thickness of the existing liquid (sludge -free) treatment
zone (are determined from 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 worksheet. The
dimensions of the lagoon as measured and the side slope are needed for calculations of sludge volume
and of total treatment volurne. If the lagoon is a standard geometric shape, the sludge volume and
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" may be used.

If the ratio 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:
R = (Vs — DSSV) / (Vz — DSSV)
Example: If DSSV = 85,000 ft3, then R = (169,860 — 85,000) / (444,174 — 85,000)
R = 84,860 / 359,174 = 0.24
