Please note that during any year when vegetation sampling related to a bond release application is conducted by the permittee, the reference azea and revegetated area shall receive the same management. A statement to this effect should be included in the permit narrative. Sectiou 2.05.4 also needs to address the requirements of Rule 4.15.7(4) describing the primary methods by which the reference are will be utilized to determine revegetation success. For example, will NP be using a weighted average between the reference area and the revegetated area? If so please include the acreage associated with the pre-disturbed pinyon-grassland and the disturbed community. Please update Section 2.05.4 accordingly. NP plans to apply the same methods and techniques used in the baseline inventory for determining revegetation success for cover, production and woody plant density. This adequately addresses the requirements for 4.15.8. NP provided a good discussion of the species diversity in the azeas to be disturbed and also in the reference azeas, but a species diversity standazd was not proposed. Based on the data presented, and also considering the reclamation goals, the Division suggests the species diversity standard include: at least two native warm season grasses with a minimum of 5% relative cover, one native cool season grass with at least 5% relative cover, one native forb with at least 4% percent relative cover and one native shrub/tree species with 3% percent relative cover. Please include a proposed species diversity standard, based on the data in Exhibit J, in Section 2.05.4 of the permit. 26a. Rule 4.15.1(5) requires a Weed Management Plan. Species to be controlled include the weeds from the State Noxious Weed List A (http.//www. colorado.gov/cs/Satellite?c=Page&cid=1174084048733&pagename=Agric ulture-Main%2FCDAGLayout) and those species included on the Fremont County list (http.•//www. ag.state. co. us/NoxiousWeed/counties/Fremont. html). Please provide a weed management plan in Section 2.05.4 of the permit. 29. NP states that Year 9 and 10 monitoring will be conducted in accordance with the sampling methods and statistical demonstrations set forth in Rule 4.15.11. Rule 4.15.11 offers several options. Please describe which sampling methods and statistical demonstrations will be used. Northfield Response: Methods and statistical demonstrations were added to page 2.05.4- 13 of the PAP. DRMS Response: Methods and statistical demonstrations were not found on page 2.05.4- 13. The Division must resolve this question prior to the approval of the permit application. Please submit a response to this question in conjunction with submittal of the forthcoming vegetation survey and revised permit text on page 2.05.4-13.
