RULE 2 - PERMITS <br />• • Houndstongue - Spring spraying (full coverage and spot) with mix of Escort, 2,4 -D amine, and <br />Activator 90 (Plateau is alternative chemical) <br />Colorado State Noxious Weed A and B lists: <br />• Bull thistle - Cutting/pulling prior to formation of seed -heads and then fall spraying with mix <br />of Tordon, 2,4 -D amine, and Activator 90 (Banvel and Curtail are alternative chemicals) <br />• Musk thistle - Cutting/pulling prior to formation of seed -heads and then fall spraying with mix <br />of Tordon, 2,4 -D amine, and Activator 90 (Banvel and Curtail are alternative chemicals) <br />• Canada thistle - Cutting/pulling prior to formation of seed -heads and then fall spraying with <br />mix of Tordon, 2,4 -D amine, and Activator 90 (Banvel and Curtail are alternative chemicals) <br />• Hoary cress (white top) - Spring spraying (full coverage and spot) with mix of Escort, 2,4 -D <br />amine, and Activator 90 (Plateau is alternative chemical), <br />For large areas or significant weed infestations, PSCM may utilize a weed - control contractor to achieve <br />overall control (typically over several years) and then utilize in -house resources (Environmental Staff, <br />student interns, summer students, contract labor) for ongoing maintenance control activities. PSCM <br />may maintain an ATV with spray -tank, spray bar, and hand - sprayer, as well as several backpack tank <br />sprayers for weed control. Chemical control activities are overseen by a U.S. -EPA Certified Pesticide <br />• Applicator and pesticide storage, handling, and use procedures and personal protective equipment are <br />utilized to prevent potentially hazardous personal or environmental exposures. Where control of <br />extensive weed infestations results in limited vegetative cover or bare - ground, the affected area will <br />either be inter - seeded or ripped and seeded, dependent on site - specific conditions. <br />Evaluation of Control Effectiveness - Generally, in conjunction with the spring Environmental <br />Management surveys, areas of previously identified and treated noxious weed infestations are <br />inspected and the effectiveness of control measures is evaluated based on reduction or elimination of <br />weed infestations. PSCM's grazing lessees and any weed - control contractors also provide similar <br />information, based on their field observations. This information is utilized in the management planning <br />process to determine the need for continued treatment and to modify treatment method(s), if indicated, <br />to improve their effectiveness. <br />2.05.4(2)(e)(vii) Soil Testing <br />Soils have been surveyed to an Order 1 and 2 level in the PSCM affected area (see section 2.04.9 <br />Soils Resource Information and Exhibit 2.04.9 -E1 Soils Information. The soils identified for <br />salvage are suitable and stripping depths have been specified, therefore no testing of these respread <br />soils other than replacement depth verification is necessary. Fertilization is not practiced on <br />reclaimed areas. The Wadge spoils do not have unsuitable plant growth characteristics and <br />throughout the long reclamation history of the Seneca II Mine, there has not been a requirement to <br />test for Wadge spoil suitability. All overburden or noncombustible waste rock from the PSCM will <br />have similar characteristics and therefore no testing is anticipated. If testing is deemed necessary at <br />• some point in time, a list of appropriate parameters and a sampling plan will be developed in <br />cooperation with the Division. <br />PSCM Permit App. 2.05 -57 Revision 12/17/09 <br />
