I doubt we will need a new work plan and you should be able to work under the <br /> existing Notice of Applicability. We may need a formal letter notifying us of your intent to conduct <br /> another round of injections, but I will discuss that with my supervisor when I am back in the office next <br /> week. <br /> Marcus <br /> From: Don Stevens [dstevensCcbecostmanage.com] <br /> Sent: Tuesday, April 14, 2015 5:17 PM <br /> To: Pierce, Marcus@Waterboards <br /> Cc: Luis Mercado <br /> Subject: RE: CA ARNG Stockton FMS <br /> Marcus, <br /> Below are answers to your questions. Please let me know if the 2015 ISCO injection and soil sample <br /> collection can be performed under the 2014 approved work plans as we are budgeting for the project <br /> currently. Also, please let me know if the existing R5 permit can be extended to cover this work. <br /> 1. Injection intervals are planned to be within the same area and roughly the same injection <br /> interval from 35-55 ft bgs. We are proposing to add a soil boring from the injection interval that <br /> matches the performance monitoring parameters. However, the approved 2014 work plan <br /> included 2 soil samples for ISCO design/performance parameters. <br /> 2. Injection strength will be similar, roughly 14%+/-,as the last injection. <br /> 3. The recent results do not trigger contingency plans. <br /> 4. No issues from the prior injection events. <br /> 5. Injection is proposed to happen between June—July 2015. <br /> 3 <br />
