Section 900.704 Upgrading
Surety Instrument
a) The owner of a lagoon must increase the total amount of surety
in place so as to equal the level of surety as calculated within 90 days after:
1) a modification resulting in an increase in the volume of the
lagoon; or
2) an increase in the cost factor under Section 900.703(b) of
this Part.

recalculation of the level of surety. Within 90 days after a request by the
owner or operator under this subsection (b), the Department must either:
1) release any surety amount above the level of surety as
recalculated based upon the owner's documentation of reduction of volumetric
capacity; or
2) conduct an inspection and determine the amount by which
volumetric capacity has been decreased.
c) If the Department conducts an inspection under subsection (b),
then the Department must release any surety amount above the level of surety as
recalculated based upon the results of the inspection.
