It also addresses groundwater sampling required in NCDWR Water Quality Certification No. 2008-0868, version 2.0 Special Condition 12, issued January 15, 2009. This data includes results of groundwater monitoring from 14 wells around the R12 reclamation area, 7 in the Yorktown Formation and 7 in the Castle Hayne Aquifer (Figure 1, attached). Baseline data is from January 2018 — July 2019, and post -blend sampling data is from August 2019-December 2019. No action is required at this time because there were no significant increases in the levels of any sampled substance above established baseline conditions, as outlined in the March 29, 2019 submittal to David May of the DWR Washington Regional Office. If you have any questions, please call me at (252) 322-8249 or email me at leff.furness@nutrien.com. Sincerely, IU 41 Jeffrey C.
