_l <br /> OUR-A) SILIER 1191tiEs <br /> OSMI Response: None of the structures listed in Section 3.3 require a crane for removal. <br /> H. Can the steel portal doors be removed with a cutting torch and CAT 365C Hydraulic <br /> Excavator or is specialized equipment required? <br /> OSMI Response: Yes, the steel portal doors can be removed with a cutting torch and an <br /> excavator;no specialized equipment is required. Alternatively, OSMI may leave the portal doors <br /> in place to act as support for the portal backfill. <br /> III. What specific equipment will be required to conduct the backfill of the underground storage <br /> room and the mill facility openings? <br /> OSMI Response: A loader and a trackhoe will be used to backfill the underground storage room <br /> and the mill facility openings. <br /> IV. For all areas to be revegetated please clarify the method of seeding. Please note that for <br /> slopes 2H.• I V or steeper, drill seeding is not recommended, broadcast or hydro-seeding may be <br /> more applicable in those situations. In addition, the resulting Reclamation Cost Estimate will <br /> include a secondary mobilization for revegetation equipment for a secondary seeding task based <br /> on the estimated failure rate and need for a secondary seed application. <br /> OSMI Response: The method of seeding will be broadcast seeding. It is not anticipated that a <br /> second round of seeding will be required; however, reseeding costs have been included in the <br /> reclamation cost tables as a contingency. Test plots done by Trout Unlimited at the Atlas Mill <br /> site located just upstream of the affected lands area demonstrated that seeding and revegetation is <br /> expected to be successful after one application.However, an additional round of seeding was <br /> included in the reclamation cost table. <br /> V. Pocking(surface roughening) is mentioned in the reclamation plan,please estimate the total <br /> area to be roughened, distribution of pocks, equipment used to create pocking and the estimated <br /> volume of material to be handled during this task. Note that drill seeding is not practical in areas <br /> where pocking is implemented. <br /> OSMI Response: As stated above, OSMI will use broadcast seeding as its method for <br /> reclamation seeding. The reference to pocking has been removed from the reclamation plan. <br /> VI. What method is proposed for the application of mulch on revegetated areas? <br /> OSMI Response: Mulch will be applied via hydro-mulching. <br /> 9 1 P a g e <br />
