Owner:
Lagoon ID
Sludge Survey Received:
Sludge Survey Performed:
Sludge Depth (Row O): (ft)
Existing Treatment Depth (Row P): (ft)
Start Date:
Facility age at time of survey:(yr)
Average Sludge Accumulation (ft/yr):
Requested Extension: (yr)
Requested Due Date
Sludge Accumulation during extension period: (ft)
Treatment Depth Available after Extension: (ft)
Sludge level OK?
Ratio Estimates Based on Depth
Ratio of Sludge layer to total trmt depth
Ratio of Sludge depth OK?
Average Sludge layer thickness (T)
Depth of the lagoon from top of bank to bottom soil surface (D)
Slope=Horizontal/vertical side slope (S)
Length at the top of inside bank (L)
Width at the top inside slope (W)
Thickness of existing liquid treatment zone (Y)
Length at midpoint of sludge layer (Lm)=L-2S(D-(T/2))
Width at midpoint of sludge layer (Wm)=W-2S(D-(T/2))
Volume of sludge (Vs)=Lm*Wm*T
Volume in gallons (Vsg)=Vs*7.481
Thickness of total treatment zone (Z)=T+Y
Length at midpoint of total treatment zone (Lz)=L-2(S)(D-(Z/2))
Width at midpoint of total treatment zone (Wz)=W-2(S)(D-(Z/2))
Volume of total treatment zone (Vz)=Lz*Wz*Z
Ratio(R) of sludge layer volume to total trmt volume
Sludge Volume Ratio OK?
Maximum extension until end of permit cycle
