Property owners may elect to postpone payment of the portion of the fee to release the DEUR, described in R18-7-604(A)(3), R18-7-604(B)(3), or R18-7-604(C)(3), on the condition that payment of the reasonable and necessary costs of releasing the DEUR is made with the request to the Department to release the DEUR from the property. Property owners electing to use this option acknowledge that the future amount of the release portion of the DEUR fee will be the amount established by this Article at the time the request for the release of the DEUR is filed with the Department, which may be greater than the amount described in R18-7-604(A)(3), R18-7-604(B)(3), or R18-7-604(C)(3) at the time the DEUR is recorded.
