2 At the conclusion of the Division's June 17, 1993 inspection, the operator was instructed to do some earthwork in order to improve drainage from the lowest portion of the area in question. At that time, there was a flat stretch in the ditch at the toe of the hill which was not adequately draining water. A Field Minor Revision (number 38) was issued which approved construction of an additional diversion across the face of the borrow area. This ditch was to intercept surface runoff and runoff from a few seeps before it reached the bottom of the hill. Prior to the end of the inspection, the operator had also excavated the ditch at the toe of the hill so that water was flowing away from the area and toward a sediment pond. At the time of the July 7, 1993 inspection, the drainage from the lower ditch was considerably better than it had been prior to the June 17 inspection. However, there was still a low-lying area with marginal drainage. A second Field Minor Revision (number 39) was issued during the later inspection which allowed excavation of additional borrow material to be used to further improve drainage from the low lying area. During the July 22 , 1993 follow-up inspection this was verified by observing that adequate ditches had been installed and positive drainage had been established. In order to fulfill the requirements of the Field Minor Revisions, the operator was required to submit permit replacement pages which detail the final configuration of the area. These pages were received by the Division on July 20, 1993, and are currently being reviewed. Issue 2 of the TDN alleges a violation of Rule 4.05.2 (1) for failure to pass disturbed area drainage through a sediment pond. The area cited is the west end of the same topsoil borrow area cited in issue 1 of this TDN. Subsequent to the inspection, the operator implemented the plans approved in Field Minor Revision No. 39 which was issued during the inspection. This work involved establishing a new grade across the toe of the borrow area to improve drainage from the area near a seep. As a result of this work, surface runoff from the entire area, except a small portion of the borrow area (NW corner) , goes to a sediment pond. The drainage from the small area drains to a gravel filter, through a straw bale filter and will be sampled to demonstrate compliance. The alternative sediment control specifics have been submitted and are being reviewed. This was verified during a reinspection of the site on July 22, 1993 . At that time, there was no violation of Rule 4. 05. 2 . Therefore, no enforcement action is being taken on this issue.
