• <br /> <br />(2) The additional monitoring portion of this report consists of three <br />separate sections; a discussion of the results of an annual rill <br />and gully inspection, an evaluation of revegetation success, and a <br />report on the hydrologic status of the Bourg Mine which underwent <br />final reclamation during the Fall of 1988. <br />Rill and Gully Inspection <br />A rill and gully inspection was conducted at the Bourg <br />property on April 26, 1990. At that time it was noted that <br />the sediment control system had, for the most part, worked as <br />designed. Spring runoff was somewhat lower than average. All <br />terraces appeared to be in good condition. No new rilling was <br />evidenced. <br />The rill along the east side of the 1988 reclamation near <br />the edge of the 1984 reclamation had not increased <br />significantly in size. It was determined by Walden Coal <br />Company personnel that the most prudent course of action was <br />to stabilize it. Hay bales were placed in the rill in order <br />to reduce flow velocity and trap sediment. <br />The rill along the west perimeter road remained stable <br />throughout the runoff season. There is evidence of some <br />vegetation establishment, however some extra seed was <br />broadcast onto the lower portion of the rill in order to <br />encourage faster coverage. Due to the size and location of <br />this rill, the MLRD staff wanted to classify this rill as a <br />drainage ditch. Because the subject area had historically <br />contained a drainage and because this area was a logical <br />location for a permanent drainage, Walden Coal has applied for <br />a technical revision to include a permanent gully into the <br />Bourg Mine permit. Approval of that revision is pending. The <br />culvert which runs under the perimeter road near the former <br />shop pad will be removed. <br />A settlement crack located at the bottom of the slope at <br />the north end of the property has been filled with topsoil and <br />seeded. Walden Coal Company staff will continue to monitor <br />that crack. <br />Another rill was discovered on August 7, 1990 during a <br />topsoil depth survey. It is located in the center of the <br />property (see attached map), and appears to be relatively <br />stable due to good perennial vegetative cover. Walden Coal <br />will place hay bales in the rill in order to ensure its <br />stability. <br />
