Bureau of Land Management <br /> �a <br /> Colorado River Valley Field Office <br /> Mineral Materials Compliance Inspection Report <br /> The recontouring that was performed in 2017 is still present and appears stable. However, evidence of recent <br /> and extensive OHV travel across the reclaimed slopes was present.The unauthorized OHV hill-climb up the <br /> tallest slope in the central portion of the quarry has been re-established by users. <br /> The "Area Under Reclamation" signs that Mayne Block and Stone installed in 2017 have almost all been <br /> knocked down. The one remaining sign is located on the northern side of the quarry. Some posts are still <br /> present, but all of the other signs are lying on the ground. <br /> On numerous occasions in 2017 and 2018, BLM requested that Mayne Block and Stone block the the non- <br /> designated OHV access points into the site.The northwestern access point to the pit was blocked with at least <br /> six downed mature pinon and juniper trees and there did not appear to be OHV travel around them. I <br /> observed that the downed tree at the north central blocked access route to the top of the quarry had been <br /> moved to the side and there was evidence of OHV travel around the moved trees.The northeastern access <br /> road to the top of the pit remained sufficiently blocked with a large downed tree. The eastern hill-climb <br /> remained successfully blocked with numerous piles of slash; however, a new route was created to the east of <br /> the blocked route. <br /> Carla DeYoung and l observed evidence of recent weed spraying activities;there were dead plants throughout <br /> the permit area. However,there were large infestations of living noxious and invasive plant species in the <br /> current permit area including multiple infestations of Musk and Scotch thistle in the central, eastern, and <br /> southeastern areas of the permit area and thick patches of Halogeton in some areas. Kochia, also an invasive <br /> plant species,was abundant in the current permit area. Grasses and sage brush were growing on some existing <br /> and stable slopes which had not been disturbed for some time. We observed the occasional native plant and <br /> species from the specified seed mix.These plants included blazing star, cateye, Indian rice grass,wheat grass, <br /> and bottlebrush squirreltail. However, these plants were not abundant. It appeared that the seed mix was not <br /> successfully establishing. <br /> Corrective Actions Required <br /> • Within 30 days of receipt of this report, Mayne Block and Stone must re-establish the road block on <br /> the north-central access point to the quarry. Do not cut down any live trees to aid in the fulfillment of <br /> this requirement. <br /> • Within 30 days of receipt of this report, Mayne Block and Stone must perform noxious and invasive <br /> weed eradication within the permit area. <br /> • BLM requires Mayne Block and Stone to reseed the permit area to ensure successful revegetation.To <br /> increase the potential for success, it is recommended that this seeding be performed in the fall of <br /> 2019. <br /> o Mayne Block and Stone may consider adding an organic soil amendment during reseeding such <br /> as compost or Sustain. <br /> o Because the Blue gramma was not observed in the permit area and the wheat grasses <br /> infrequently observed, Mayne Block and Stone may also consider updating the seed mix and <br /> replacing a portion or all of these grasses with Wyoming sagebrush (at 0.1 Ibs per acre) or <br /> Rubber rabbitbrush (at 0.25 Ibs per acre). <br /> Page 2 of 10 <br />
