r -4- To determine whether the sediment ponds are being properly maintained the operator should submit the latest sediment level survey. If one has not been done recently, a survey must be conducted to determine which ponds need cleaning. Additionally, to assist inspectors in the future to judge sediment levels, the Division is requesting that CYCC install a sediment staff gage or a marker. CYCC will still have the option of doing a survey. ~ki{~ `.~'~'~" ha.e_ loan .~11ea LoSfi" -}opnS,aQl~;c, y,,.v ~cc•,., ptrtr a Win pv,+d6~+~-mac, ~~ ~ ~.. .r~' Fnr Pana ~, Coal fines within the Foidel Creek buffer zone are prevalent in the tipple 2 area from the coal stockpile, trucks or road. Some measure ~r-~m;~~o~l~m't should be undertaken to reduce the amount of coal fines from blowing into '9i- the buffer zone. Possible solutions are windbreaks, better dust ~42/,~ suppressants or fences (fabric fence). Has CYCC tried any of these or taken any other preventive measure to reduce the amount of coal fines blowing into the buffer zone? According to the permit application and the findings in the OSM TEA, permanent diversion ditches around the excess overburden stockpiles are "~,}~ a,a,,d ob 2 to be constructed. Recently, a design change was approved for the ditch around overburden stockpile No. 1 and it is in the process of being rs cor,Pu'~e- constructed. There is no evidence that the permanent diversion ditch _ around overburden stockpile tJo. 2 has been constructed. Therefore, it is ~ oF~2-• "`5~.°u~d` necessary that CYCC construct the ditch around overburden stockpile No. 2 ~ ~J,rn pk~ . according to ttie approved plan. A professional engineer certification that the ditches have been constructed in accordance with the approved ail\ Sub n,.~ wl plan is required per Rule 4.09.1(11). q~ ~•t,~ Because of the numerous revisions regarding the hydrology maps - No. 13 1yQ and 14, the Division finds that these maps need to be revised to reflect the current status. ~ Sp•~•1. Rule 4.05.11(11) requires the operator to submit proof of compliance with Mine Safety and Health Administration and the State Engineer Office's ~' pond inspection requirements. Rule 4.05.6(11)(c) requires pond sc~S5e5}va~'o•n,afi inspections and reports for ponds not meeting and the (SEO) criteria. ~,-~,,., p,b The permit application does not require this and it needs to be revised so that the pond inspection reports are submitted. NPDES requirements have been deactivated for all reclamation areas that are graded to approximate original contour, ,iQhich includes Area 1 and µ all of Energy Mine No. 2. To ensure that the operator is minimizing effects to the hydrologic balance by siltation and contributions of suspended solids the Division acrd'needs TSS or SS data from the deactivated pond sites. (This data is independent of NPDES standards CYCC is collecting this data form the deactivated sites which should included in the Annu__ a~ology Report. ~S~ /~ ~~~6~ be Z e~~~xu The Annual Hydrology submitted by Colorado Yainpa Coal Company ~~ have been found t e unsati •n their present form for the purposes of review b e Division.
