Pond 3 was holding water and not discharging, Pond 4 was not observed as it was release <br />with SL4. NPDES #7, which is at a ditch near the office that was not discharging. On going pond maintenance <br />items are listed below in the general mine compliance section. <br /> <br />The broken pipe coming out of the bottom of Pond 2, as noted in the complete inspections in June 2017 and <br />August 2017, and October 2017 remains in the process of being repaired. No water was discharging from the pipe <br />at the time of inspection. <br /> An additional pipe, of smaller diameter, right next to the one repaired appears highly corroded and <br />is beginning to leak. This pipe needs to be fixed before it breaks. This should be done as soon as <br />possible and before winter weather and freezing occurs. See photo below.
