Current through Vol. 41, No. 19, June 17, 2024

Section 252:517-17-8 - Economic life of CCR unit

(a)New CCR unit. The economic life of a new CCR unit shall be based on the area to be initially permitted for waste disposal, not on the total permitted area.

(b)Economic life. For the purposes of determining the pay-in period for a trust fund or escrow account used as a financial assurance mechanism, or another approved mechanism that allows pay-in over a specified period of time, the economic life for a new CCR unit shall be the lesser of fifteen (15) years from the initial receipt of waste or the life as calculated in accordance with (b) of this Subsection.

(c)Calculation. The life shall be calculated according to the following formula: L = (V x D) / W, where

(1)"L" equals the life of the CCR unit, in years;

(2)"V" equals the total volume of air space in cubic yards available for waste disposal and daily cover. V shall be calculated from the top of the protective layer to final contours minus the amount of air space taken up by final cover;

(3)"D" is the anticipated density of waste compacted in place in pounds per cubic yard. Until an alternative value based on a history of operational practice can be documented, D must not be more than 1000 pounds per cubic yard (1000 lbs/cy); and

(4)"W" is the amount of waste expected to be disposed during one year of operation in pounds per year, until the owner/operator can document actual waste disposed based on a history of operational practice.
