Please provide clarification of potential solutions to permeability issues arising as a result of the intersection of the <br />utilities' pipes (i.e. the water main in the berm between current ponds 2 and 3, also any gas and sewer lines) and the <br />proposed slurry wall. <br />17. As discussed during this inspection, please provide documentation describing how the operator will address the <br />apparent lack of suitable fines on site for slurry wall construction. The requirement is between 20°k and 50% fines for <br />the slurry mixture, and the operator states that present site conditions provide merely 24% to 28%. <br />18. Please provide additional information regarding the location and source of borrow to be used on site. <br />19. Please provide an explanation as to the use or disposal of the cement stockpiles found on site during the inspection. <br />20. Please explain how the asphalt road at the south edge of the ponds (between the main pond and the St. Vrain) will be <br />reclaimed. <br />21. Please provide the acreage of the permitted area and clearly illustrate the size and location of the temporary sediment <br />ponds on a map. <br />22. Please provide documentation revising the grade of the swimming area from 3h:1v to 5h:1v as required by Rule <br />3.1.5(7). <br />23. There appears to be a minor knapweed population on the southwestern side of the current middle pond. Please submit <br />a weed control plan per Rule 3.1.10(6). <br />24. Please choose one of the three options for calculation of the slurry wall bond from the information provided by DMG <br />during this inspection. The current bond held is $46,800. <br />25. Please provide additional detail for revegetation techniques that will be implemented - i.e. mulching (how much/acre <br />and with what) and fertilizer (how much/acre and with what). <br />This list was compiled as a courtesy to the operator so that information can be gathered. However, DMG would appreciate it if <br />these items were not submitted until after the adequacy review letter has been received by the operator. <br />As a courtesy DMG will also provide a recommended seed mixture with the adequacy review letter, that the operator may <br />choose to utilize at his or her discretion. <br />Responses to this inspection report should be directed to Deb E.
