Appropriate storm water controls will be used to retain runoff sediment. <br />All remaining ditches and sediment control facilities will be reclaimed following the specifications in this <br />amendment and applicable Mined Land Reclamation Board regulations. Storm water control structures <br />and facilities will be removed and the areas reclaimed once the major areas of site reclamation are <br />successfully revegetated and stabilized so that storm water controls may safely be removed. <br />There are no large siltation structures at the site. Should one become necessary in the future it will be <br />removed during reclamation. No new earthen dams will be constructed under this Amendment. <br /> <br />Post-reclamation water monitoring is not anticipated. Once the mining has ceased, the water treatment <br />system will continue its operations during reclamation activities. It is anticipated that once vegetation <br />has taken hold and all reclamation activities have been complete, the mine water will no longer require <br />treatment. Following the end of mining, water samples will be taken from the inlet of the water treatment <br />system as well as the discharge. The inlet samples will be compared to water baseline data. If the <br />water treatment inlet water is in line with baseline water quality, the water treatment system will be <br />disassembled and removed.
