Susan Burgmaier -6- November 18, 2014 <br />construction it would not be considered supplemental and design <br />information will also be required. <br />BRL: It is unknown when the ADS drain was installed. The purpose of the <br />pipe is to drain seep S -8. It was not installed in support of mine facilities and <br />it is not part of the sedimentation control plan. Runoff from the surrounding <br />areas will either be routed to Ditch C -1, or be treated by a waddle on the light <br />use road. <br />Half culvert on the east outslope of the office bench, draining to Ditch C- <br />17- BRL indicated that this culvert is not part of the sedimentation control <br />plan. Please provide a description of the half culvert on the east <br />outslope of the office bench, draining to Ditch C -17 including its <br />intended function and the source and destination of water routed <br />through the structure. If the culvert has been installed in support of <br />mine facility or road construction it would not be considered <br />supplemental and design information will also be required. <br />BRL: The installation of the half culvert is supplemental. It is not designed, <br />but installed at a low spot in the parking lot. The flow from the parking lot <br />office is generally directed to D -C17 or D -C24, with a very small portion being <br />passed through the half culvert. <br />Item Resolved. <br />Culvert perpendicular to Culverts J11 and J12, parallel to the Fire <br />Mountain Canal and running under the Gob Pile #3 haul road —BRL <br />indicated that this culvert was not part of the Bowie No. 2 sediment control <br />plan. Please indicate whether the Culvert perpendicular to Culverts <br />J11 and J12, parallel to the Fire Mountain Canal and running under <br />the Gob Pile #3 haul road (conveying the Deer Trail Ditch) was <br />installed to facilitate construction of the Gob Pile #3 haul road. If the <br />culvert was installed for the haul road, please submit design <br />information for the culvert. <br />BRL: It is unknown exactly when this culvert was installed, but it was not installed to <br />facilitate construction of the gob pile #3 haul road. Looking back at old permit maps, <br />this culvert was installed prior to construction of the gob pile haul road, it is used to <br />convey flow in the deer trail ditch only. Therefore a design is not required. <br />10. Item Resolved. <br />11. Item Resolved. <br />12. Item Resolved. <br />
