Since <br />that time we have met with their staff and reviewed the MLRB <br />application with them. They concurred with the procedures in the <br />application that would handle erosion control and suggested a <br />ponding method to control sediments. We prepared the attached <br />addendum for inclusion in the MLRB application and hand delivered <br />it to the SCD office for review before submitting it to the MLRB. <br />The SCD response arrived today. Since the sediment basin meets <br />the requirements of the SCD we now submit the addendum for <br />inclusion in the application. <br />Sincerely, <br />/'~ ~, G~ <br />Larry E. O'Brian <br />
