The reports were <br /> received on; August 1 , 2019 (July report), September 18, 2019 (August report) and <br /> October 9, 2019 (September and Yd quarter report). The reports corer the time period of-, <br /> July 1, 2019 through September 30, 2019. The Division finds the reports to be in <br /> compliance with Rule .0 .1 . <br /> There are two outfalls associated with the CO-002714611PI S permit, Cutf ll 002 and Cutfall <br /> 016. During the months of July, August and September no flow was recorded out of Cutf ll 002. <br /> No exceedances occurred at this location. Outfall 016 discharged during July, August and <br /> September. The reports indicate that no a ceedances occurred for the reported parameters during <br /> the quarter. to other concerns were identified during this time period. <br /> The 11vision was notified that the discharge monitoring point for Cutf ll 016 was re-installed on <br /> May 17, 2019. Parameters monitored at the station have shoved no major changes in water <br /> quality. The rate of grater flog has changed between the months of May and June. The Daily <br /> max flow rate 'in May r prior to the re-installation of 016 was 0.415 NICK or 288.2 GPM. The <br /> maximum daily flow recorded in June after the re-installation of 016 was 0.211 NICK or 146.5 <br /> GPM. The gauge was thought to have been placed incorrectly in the culvert prior to the re- <br /> installation resulting in inaccurate flow recordings. Recorded data for the flog through Cutfall <br /> 016 has remained consistent during the Yd quarter. Flows ganged from 111 to 130 gpm during <br /> the 3rd quarter. <br /> This concludes the Division's review of the 3rd Quarter 2019 Discharge Monitoring Reports for <br /> the Roadside Portals Mine.
