The <br />current abatement deadline for this NOV is Thursday, July 17th, <br />Step 1 of this NOV required Seneca to remove all sloughed fill <br />material from the channel of Annand Draw near culvert YB-6. The <br />fill has been removed from the channel, the road slopes reshaped <br />and the silt fence at the toe of each slope has been installed, <br />therefore this portion of the abatement has been completed. Step <br />2 of the abatement required us to grade the fill material located <br />adjacent to RCR 27 to the final 5:1 slope proposed in TR-05. The <br />slope has been graded and the final drainage ditch established. <br />We still need to place the erosion control matting in the <br />drainage to finish this portion of the abatement. Finally, step 3 <br />of the NOV was to complete the construction of the relief drains <br />on Yoast Haul Road A per the designs in the permit. We have just <br />initiated the work on these downdrains. I am asking for a 15-day <br />extension of the current deadline to August 1st. <br />Should you or any other members of the Division have any <br />questions regarding this information, please do not hesitate to <br />contact me. <br />Sincerely, <br />~W. ~2.- <br />Michael G.
