<br /> <br /> <br />., <br />6. Reference to the sediment control plan, sediment pond design details, and <br />surface water monitoring in Sections 2.04.5, 2.04.7, 2.05.6(3) and other <br />sections should be updated to reflect the technical revision changes which <br />have occurred since permit issuance. Technical revision text needs to be <br />incorporated into the application and portions of the text which no longer <br />apply should be deleted. Replacement pages should be numbered and dated. <br />7. The Division has noted that a small infestation of the noxious weed, Canada <br />thistle, has become established on the upper bench slope below the upper <br />diversion ditch. A plan for controlling the weed infestation and stabilizing <br />the slope with desirable vegetation needs to be submitted for inclusion in the <br />application. Other disturbed areas such as berms, ditches, pond embankments, <br />etc. should also be stabilized with desirable, perennial vegetation, and a <br />plan for temporary vegetative stabilization of these areas should be <br />incorporated into the application. <br />8. Section 4.20 of the permit application contains a subsidence monitoring plan <br />and indicates that proposed subsidence monitoring monuments will be installed <br />and monitored at least twice prior to any underground development work. To <br />date, the monuments have not been installed and therefore, the baseline <br />monitoring has not been performed. The application text will need to be <br />modified to clarify that the monuments will be installed and monitored as <br />described prior to resumption of active status. <br />9. The current reclamation map does not provide sufficient detail to document the <br />feasibility of the proposed final topography. Properly certified maps at a <br />scale of 1" = 200' or larger should be submitted to accurately depict both the <br />current and proposed final topography. Contour interval within the affected <br />area should be no greater than 5 feet. A minimum of 3 cross sections <br />depicting the current and proposed final topography should be submitted in <br />addition to the re guested maps. <br />10. The Blue Flame Mine in its current configuration and layout is set up for <br />mining on a very small scale, with Droduction limited to a maximum of 50 tons <br />per day or 13,200 tons per year, and the permit was issued based on the <br />assumption of the small scale operations. Any anticipated increase in the <br />scale of operations or production level will necessitate significant <br />operational and reclamation changes and would reguire a permit revision. At a <br />minimum, the revision would need to address MSHA mandated portal <br />modifications, additions] coo] storage and handling facilities, necessary <br />access and haul road improvements, and an adeguate plan for disposal of <br />underground development waste and unsalable coal fines. If an increased scale <br />of operations is anticipated, the Division would encourage that a permit <br />revision application be submitted well in advance of the projected start-up <br />date. The most efficient approach would probably be to submit a completely <br />~ revised application document which would replace the current document. The <br />~ current document is somewhat out of date, lacks pagination, and insertions and <br />I revisions are not well integrated into the text and are not dated or numbered. <br />-5- <br />
