As required by Section B. 1 of Part II of UIC Permit NE012261 1, a second sample was collected within 24 hours and analyzed for the three excursion indicator parameters. The results of the second sample exceeded the SCL for chloride. In accordance with Section B. 1 Part II of the UIC permit, CBO increased the sampling frequency for SM10-21 to weekly. Weekly samples were obtained from May 27, 2015, to July 29, 2015. The samples collected on July 15, 22, and 29, 2015, were below the excursion criteria from Section B. 1 of the permit. Based on these results, CBO removed SM10-21 from excursion status. In accordance with the requirements of Section B.I1, weekly sampling continued for an additional three weeks. During the stability monitoring period, the excursion parameters were not exceeded and SMI0-21 was returned to biweekly sampling status.
