ditches, pipelines, or the diversion during the field review. Pond 9 was dry and <br />supported hydrophytic vegetation. <br />Field measurements were taken to spot heck RRDA's drainage control structures and <br />were approximate. Measurements taken were as follows: <br />A. South Diversion: <br />1. culvert @ access road crossing over south trending section @ <br />southeastern part of diversion: <br />`78" diameter. clear at both ends <br />2. culvert @ access road crossing over east-west trending section: <br />@ south end of diversion: <br />'18" diameter, clear at both ends <br />3. @ extreme southwestern end along rock wall, near outlet: <br />'top width = 8'; depth = 15"; diversion well vegetated <br />4. @ south end, about 100' east of location #3 above: <br />'top width = 17'; depth = 14"; diversion well vegetated <br />5. @ pt. near culvert in east-west trending section at road: <br />`top width = 13'; depth = 21"; diversion well vegetated <br />6. @ pt. 100' east of the northwest end of the diversion: <br />'top width = 10.5'; depth = 16" <br />B. Lower Catch Ditch 1: <br />1. @ pt. 175' south of the inlet to pond 8: <br />`top width = 6'; depth = 11.5" <br />C. Lower Catch Ditch 2: <br />1. @ pt. 100' north of inlet to pond 9: <br />'top width = 5'; depth = 14" <br />Conclusions <br />DMG planned to follow-up on a few items noted during the field review before a <br />determination of compliance could be made for all aspects of the piles that we checked. <br />First, the permittee was given until Friday, August 8, to repair the section of the <br />northwest collection ditch at CRDA-1 that was filled with coal refuse.
