The land surface and mineral ownership are State and federal. The areas within the bond release were reclaimed between 1978 and 2005. Permanent features of the bond release are shown on Map 2, which accompanied the SL-4 application and is available on Laserfiche. The drainages were walked to determine reclamation success and the revegetated areas observed for vegetative cover, diversity, and potential presence of weedy species. A detailed write-up of the bond release areas and the evaluation of the release of these areas will follow in the Divisions SL-4 findings document. With a few minor exceptions noted below as well as in the SL-4 adequacy letter, dated 8/15/2017, the SL-4 was stable with no erosional features and very well vegetated. One area along a steeper section of permanent access road F1 had notable down-cutting. The operator has armored this downcut area along the road as shown in the photo below. The operator submitted responses to the 8/15/2017 adequacey letter on October 27, 2017. The Division is currently reviewing this submission for 418 Acres for Phase III release. SIGNS AND MARKERS – Rule 4.02: • Additional disturbance boundary markers should be around the portal and facilities areas
