may have been built different than designed, so measurements should he mado.)

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 O and P, respectively). In this example, the average sludge
layer thickness Is 2 5 feet and the existing liquid treatment zone is 3.5 feel If the lagoon has a designed sludge storage volume,
see notes atend of the worksheet Tne dimensions of the lagoon as measured and the side elope are needed
for ra curalcns of sludge volume and of total treatment volume ;If tl-e lagoon is a standard geometric shape, the sludge
volume and Pre treatment volume in the lagoon can be esbmatec by using standard equations. For approwroate vo.umes
o` rectangular lagoons with constant side slope, calculate length and wldtY at the midpoint of the layer, and multiply by layer
tl cvtess to calculate layer volume, as shown in the examp e. For kregularshapes, convert the total surface area to a square
or rectangular shape For exact volumes for lagoons with constant side slope, the "PristnDldal Equations' maybe used.

If the ratio R exceeds 0.50, than a sludge Plan of Action may be required. Check with DWO for
Information on filing the Plan of Action.
Note If the agcon has a designed sludge storage volume (DSSV), subtract that volume from both the volume
of sludge (Vs) (Item 8) and from the volime of total treatment zone (Vz) (Item 14). and take the ratio.
Then, R = (Vs-DSSV) / (Vz - DSSV)
Eummple If DSSV = 85,OOC its, then R = (169,860 - 65,ODC) / (447;174 - 85,OD0) = 84,8601362,174 = U4.
