the "Unsuitable Subsoil Backfll Mitigation Plan" will be followed to mitigate the <br />problems as much as possible. <br />Both the "Regraded Spoil Backfill Material Monitoring Program" and the "Unsuitable <br />Subsoil Backfll Mitigation Plan" are outlined in Section 2.05.4(2)(d) of the NHN Permit. <br />Acres Topsoiled <br />Work consisted exclusively of pre - production activities and initial boxcut excavation. No <br />topsoil was re- distributed during 2013 on the NHN Permit. <br />In the future, when areas are being topsoiled, the procedures as outlined in Section <br />2.05.4(2)(d) will be followed. Before topsoil is re- applied, the regraded spoil material <br />will be scarified to a depth of 12 -24 inches to reduce compaction. <br />After final grading and topsoiling, the total depth of topsoil and suitable subsoil must be <br />at least 3 -4 feet thick as described in Section 2.05.4(2)(d). <br />Vegetation Planted <br />No permanent seeding or revegetation was performed during 2013 on the NHN Permit. <br />Temporary seeding of the topsoil stockpiles, pond embankments, and collection ditches <br />using the Permit approved seed mix #3 (dryland) was performed. These areas are <br />depicted in Map 2013 -6 associated with this report. <br />Previously Re- vegetated Areas <br />No re- vegetation, fertilizing, or farming activities have taken place on the NHN Permit in <br />2013. <br />Re- vegetation Monitoring Reports <br />Work consisted exclusively of pre - production activities and initial boxcut excavation. No <br />reclamation related re- vegetation, fertilizing, or farming has taken place on the NHN <br />Permit in 2013. For Irrigated Pasture, interim re- vegetation monitoring will occur in years <br />3 (for phase 2) and 7 (prior to final bond release). Final monitoring will occur in years 9 <br />and 10 following final reclamation or later (Sec. 2.05.4(2)(e) pg. 34 -35). These reports <br />will be provided here in future Reclamation Reports when required. <br />Weed and Pest Control Activities <br />Spraying for noxious weeds was evaluated on approximately 91 acres of the NHN permit <br />area during 2013. Map 2013 -4 shows the general areas and number of acres that were <br />sprayed. As noted on the weed applicator's invoice, 80 acres of the total area received <br />weed spray. <br />BackCountry Vegetation Management LLC, Colorado License #11824, of Norwood, CO <br />conducted the spraying activities. Russian knapweed was the main target. <br />M:\DATA \Word\NHN Ann Rec Reports\2013\NHN 2013 Annual Reclamation Report.doc <br />-4— <br />
