(Also see item#3 in <br /> second adequacy letter—determining how many cubic yards of backfill will be required is also a critical item <br /> for calculating the reclamation bond required). <br /> (d)the size of area(s)to be worked at any one time. DRMS assumes that the entire affected area of the permit <br /> may be impacted by mining activity. <br /> (e)An approximate timetable to describe the mining operation. The timetable is for the purpose of establishing <br /> the relationship between mining and reclamation during the different phases of a mining operation. You will not <br /> be required to meet specific dates for initiation, or completion of mining in a phase as may be identified in the <br /> timetable. This does not exempt you from complying with the performance standards of Section 3.1. Such <br /> timetable should include: <br /> (i)an estimate of the periods of time which will be required for the various stages or phases of the <br /> operation; <br /> (ii)a description of the size and location of each area to be worked during each phase; and <br /> (iii)outlining the sequence in which each stage or phase of the operation will be carried out. <br /> (Timetables need not be separate and distinct from the mining plan,but may be incorporated therein.) <br /> (f)A map(in Exhibit C-Pre-Mining and Mining Plan Maps(s)of Affected Lands, Subsection 6.4.3)may be used <br /> along with a narrative to present the following information: <br /> (i)nature,depth and thickness of the ore body or deposit to be mined and the thickness and type of <br /> overburden to be removed (may be marked "CONFIDENTIAL," as per Paragraph 1.3(3)); and <br /> (ii)nature of the stratum immediately beneath the material to be mined in sedimentary deposits. <br /> (g)Identify the primary and secondary commodities to be mined/extracted and describe the intended use; and <br /> (h)name and describe the intended use of all expected incidental products to be mined/extracted by the proposed <br /> operation. <br /> (i) Specify if explosives will be used in conjunction with the mining(or reclamation). In consultation with the <br /> Office,the Applicant must demonstrate pursuant to Rule 6.5(4), Geotechnical Stability Exhibit,that off-site areas <br /> will not be adversely affected by blasting. <br /> DRMS will require additional discussion/narrative to be provided with the blasting report and monitoring that <br /> was submitted with Adequacy Response#2. Discussion should focus on how this monitored blast is <br /> representative of blasting activity at the site (number of holes,depths,spacing,charges,stemming material, <br /> etc.,)and how the provided materials address all items contained in the "Key Elements of a Blasting Plan" <br /> guidance document which has been attached to this letter. <br /> In addition a map should be provided to illustrate where the monitored blast took place and where the <br /> monitoring instruments were placed. The operator should also be aware that additional monitoring maybe <br /> required in the future to demonstrate that established blast limits will not be exceeded if blasting activity gets <br /> closer to the permit boundary or off-site structures. <br /> 0) Specify the dimensions of any existing or proposed roads that will be used for the mining operation. Describe <br /> any improvements necessary on existing roads and the specifications to be used in the construction of new roads. <br /> New or improved roads must be included as part of the affected lands and permitted acreage.Affected land shall <br /> not include off-site roads which existed prior to the date on which notice was given or permit application was <br />
