<br />RESPONSE TO MISCII,LANFAUS QUESTIONS IN <br />NOVE?IDII2 1, 1991 LETTER <br />The following responses are provided for items that did not actually fit <br />into the main format of this response. All other items in the November 1, <br />1991 letter are discussed in the preceding information. <br />ITEl7 8: C<alverts: There is only one true culvert on the site and that is the <br />72" steel culvert that extends under Academy Boulevard and carries the <br />Fountain Mutual Irrigation Ditch. The road tunnel under Academy Boulevard <br />could act as a culvert, but this structure will remain. The tunnel was built <br />in 1972 when Academy was extended southward through this area. Its removal <br />would be impossible without total disruption of traffic on Academy Boulevard. <br />The only way it could be eliminated would be to fill the tunnel completely <br />with sand, rock, or some other material. <br />Other culverts on the site connect some of the old sediment basins, but ~ <br />these are no longer needed or functional and are not generally exposed. These <br />were generally small in dimension and provided overflow routes between , <br />sediment basins. They never served any function for storm water drainage from <br />the operation. Storm water collects in depressions and usually seeps into the <br />ground very quickly. <br />Item 9: Diversion and/or collection ditches that will be reclaimed: <br />None exist on site that serve this purpose. Any incidental drainage <br />routes from the pit to adjacent lands are not through such controlled <br />structures. It is believed that sheet flow provides the most rapid means of <br />controlling runoff because it provides the greatest surface area for seepage <br />into the ground. Therefore, any diversions or collection ditches that locally <br />direct drainage away from buildings or equipment so the water can merge with a <br />general sheet flow pattern will be reclaimed as part of the backfilling and/or <br />grading process and should be covered by those costs. <br />Item 13: Buried tanks: There are no buried tanks on site. <br />Page 16 Bonding Information M-73-007/M-77-213 January 7, 1992 <br />
