A bond or alternative financial assurance is required for each site and multiple sites of less than one acre by the same operator, except that government units are not required to obtain bonds or alternative financial assurance.
Note: The base of 1989 dollars requires that the bonding level must be adjusted to reflect inflation or the cost of living increases. For 1992, the inflation of 4.6 % for 1989, 6.1% for 1990 and 3.1% for 1991, or a total of 14% (1.046 x 1.061 x 1.031 = 1.144) must be added to the listed rates resulting in amounts of $ 2280 per acre or $ 0.285 per cubic yard. For permits issued after 1992, remember to correct for cost of living adjustments for all years back to 1989.
