This letter also serves as a follow-up to January 21 and 24 messages recorded on your voice-mail. During the week, the active pond averaged 0.94 ppm CN-wad and 1.32 ppm CN-total. The collection pond averaged 0.36 ppm CN-wad and 0.56 ppm CN-total. The weekly sample of the inactive pond, collected on January 19, showed 0.16 Fpm CN-wad and 0.16 ppm CN-total. As per my voice-mail message of January 21, the active pond (lower pond) sample for January 20 showed cyanide concentrations of 4.12 ppm CN-wad and 4.69 ppm CN-total. Also, as per my voice-mail message of January 24, the active pond sample for Janaury 21 showed a slightly high CN-total value of 4.54 ppm with a 3.55 ppm CN-wad value. SamFles collected on January 22 showed concentrations of 3.32 ppm CN-wad and 3.93 ppm CN-total. As specified in TR-O1C, the DMG was immediately notified of the cyanide levels. The January 16-22 weekly average and the January simple ironthly average for pond compliance will not be significantly influenced by this anomaly. We will continue to closely monitor the situation and will inform the Division of any changes. If you have any questions, please call. Sincerely, f'~'w-,o~ S~}- Alana L.
