Do you have any comments?

In section 2A, average daily withdrawal was also entered as the maximum daily withdrawal per guidance from John Barr for the 2015 report and therefore kept the same. The data is not collected on a daily basis. Well totalizers are read monthly. Pumping capacity is entered in 2B; however, is not used to calculate the maximum daily withdrawal as the site does not pump at max capacity. Wells are pumped at a steady rate throughout the month. In section 3B, the discharge capacity of 001 is listed as the same as the averaged discharged. There is no permitted limit on 001 outfall because the storm water also discharges through here. Well H2 ceased to operate in March 2020 and well OG2 ceased to operate in May 2020. Well C ceased to operate prior to 2020. All wells were properly abandoned. As of October 1, 2020, the new company name is INV Performance Surfaces, LLC, and INVISTA Wilmington Plant (Facility Name)
