Doug Smith <br />Page 2 <br />March 15, 2017 <br /> <br />required for use on BLM and USFS lands (described in Tables 4 and 5 of Exhibit 2.05- <br />E6, respectively). <br /> <br />Weeds identified as requiring control during 2015 were “thistles, hounds tongue and <br />whitetop”. Oxbow employees sprayed disturbed areas with Crossbow and Curtail <br />herbicides. These products are manufactured by Dow Chemical and are approved for use <br />in Colorado. Curtail is described as “a broad-spectrum broadleaf herbicide providing <br />outstanding control of Canada thistle and other problem weeds in small grains”, and is <br />mentioned specifically in the weed control plan in Exhibit 2.05-E6. Crossbow is <br />described as “a post-emergent product that targets woody plants and brush – such as <br />blackberries and poison oak – as well as annual and perennial broadleaves, while leaving <br />grasses unharmed” but appears to have been discontinued by the manufacturer. <br /> <br />Reclaimed areas were inspected for rills and gullies deeper than nine inches, but none <br />were identified. <br /> <br />The 2015 ARR identifies 104.87 acres that have been backfilled and graded and are therefore <br />eligible for Phase I bond release; additional acreage was seeded at least 10 years ago, and could <br />be eligible for Phase II/III bond release. There appears to be an error on the form in the value of <br />this acreage. Per Exhibit 1, the sum of acres seeded in 2006 or earlier is 45.16, not 22.5 as shown <br />on the ARR form. Please review the form, correct the error if necessary, and re-submit. Feel <br />free to contact me if you have any questions. <br /> <br />Sincerely, <br /> <br /> <br /> <br /> <br />Leigh Simmons <br />Environmental Protection Specialist <br />
