The 1989 Rill and Gully <br />Plan was submitted to the Division on May 23, 1989. Newly <br />identified rill areas from the 1990 survey are shown on <br />the enclosed aerial photograph. - <br />None of the newly identified rill areas appear severe <br />enough to prohibit successful revegetation, disrupt the <br />achievement of the postmining land use, or cause a <br />degradation of water quality standards for a receiving <br />stream. At this time, remedial action is not warranted in <br />these areas; however, they will continue to be monitored. <br />If any of the identified areas increase in severity or <br />cause damage to adjacent areas, the source of the problem <br />will be corrected, the rill or gully will be filled or <br />regraded, and the area will be reseeded. <br />Rill and gully repairs made in areas identified during the <br />1989 survey were also inspected for effectiveness. All <br />1989 repair activities appear to have been successful in <br />these areas. Action taken in 1989 survey areas were <br />consistent with the plan presented in the May 23, 1989 <br />letter to the Division. <br />If you have any questions either contact me or Roy Karo <br />who can be reached at the Seneca Mine. <br />Sincerely, <br />~-' James S.
