The erosion gully on the backfilled <br /> slope has been repaired with fill material and re-grading. The steps taken seem to have solved the <br /> problem but we will inspect the drainage pattern after the next major storm event and determine if <br /> additional re-grading is required. Please contact me with any further questions or comments. <br /> Sincerely, <br /> Stephen A. Onorofskie <br /> Mine Manager <br />
