La Plata proposes to reduce access to the upper bench, to reduce the <br />height of the aerial conveyor as required by the Mine Safety and Health <br />Administration (MSHA), and to reduce access to the tipple and loadout <br />area. Since these actions are in accordance with the required <br />abatement, these actions are deemed appropriate by the Division. <br />C. Cessation Order C-85-067 issued on July 22, 1985 was for "Failure to <br />maintain an adequate and functional drainage control system. All <br />ditches and culverts are blocked causing runoff to be discharged <br />off-site without passing through (the) sediment pond". This CO related <br />to the entire mine site. Abatement for this enforcement action is to <br />" .. clean all ditches and culverts, ensure all structures are <br />functioning properly, and control all runoff from the haul road and <br />lower bench (facilities area)". <br />La Plata proposes the following actions. <br />1. La Plata will clean out the sediment that has accumulated in the <br />sediment pond disposing this material in an appropriate manner. <br />2. La Plata will seal this sediment pond with non-toxic bentonite to <br />protect the alluvial valley floor (AVF) from potential mine <br />drainage contamination. <br />3. La Plata will reestablish Ditch 1 and 2. <br />4. La Plata will fix the piping at the inlet of Culvert A which allows <br />drainage to bypass the sediment pond. <br />5. La Plata will unblock Culvert B and establish drainage to the <br />sediment pond. <br />6. La Plata will unblock Culvert C. <br />7. La Plata will establish a drainage ditch along the upper bench <br />access road to correct road failure problems and control drainage. <br />Since these actions are in accordance with the required abatement, <br />these actions are deemed appropriate by the Division. <br />D. Cessation Order C-85-068 issued on July 22, 1985 was for "Failure to <br />permanently seal (the) underground entries". This CO related to the <br />four open portals on the upper bench. Abatement for this enforcement <br />action is to "Seal open portals permanently in compliance with <br />Rule 4.07.3 and 4.14". <br />La Plata does not propose to permanently seal these portals but rather <br />proposes to reduce access to these portals. While this action does not <br />completely satisfy the required abatement, it does reduce the danger to <br />the public's health and safety. La Plata should consult with Mine <br />Safety and Health Administration (MSHA) or the Division of Mines <br />regarding appropriate management of the portals. The Division deems <br />this action appropriate. <br />-2- <br />
