Please provide this information along with an annual groundwater flow rate in feet. • Please provide well construction log$ for the wells to be used as injection. • Please sample the following monitoring wells prior to injection [baseline], and 3 months, 6 months, 9 months, and 12 months after injection: IW-1, IW-3, IW-7, MW-4, MW-7, MW-8, MW-10, MW- PT, and RW-C. Also, please collect updated groundwater elevation data from all monitoring and injection wells on-site prior to the initial injection. The revised monitoring plan could be inserted as a new, replacement page in the Application (Section 7). • Please add the following parameters to the monitoring plan: temperature, dissolved carbon dioxide, and metals per EPA 3030C. • The cross section line on Figure 10 was omitted. Please submit a corrected Figure 10 showing wells used in the geologic cross-section in Figure 11. • Due the revised injectants to be used for this event (i.e., no ferrous sulfate or citric acids are to be used), please provide updated volumes of injectants (if any) and the calculations used to justify the amount. • There is a reference to a bench-scale study in Section 5 of the Application (page 5-2), but was not included.
