Greatly appreciate the support and planning efforts. I am available to discuss over the phone tomorrow, <br />if you want. <br />Thanks, <br />Donald L. Stevens, PE QSD <br />Project Manager/Environmental Engineer <br />Direct 916.706.3379 I Cell 559.824.8711 <br />dstevensecostmanage.com <br />From: Pierce, Marcus@Waterboards [mailto:Marcus.Pierce@waterboards.ca.gov] <br />Sent: Wednesday, April 8, 2015 10:05 AM <br />To: Don Stevens <br />Subject: RE: CA ARNG Stockton FMS <br />Hi Don, <br />I am working out of the office through next week, so email me if you need to reach me. It is likely we <br />don't need a new work plan and the additional injections should be covered under the existing <br />NOA. However, I need some more information to make a decision and don't have the latest monitoring <br />report/work plan with me. Please answer the following: <br />Are you injecting at the same locations/depths as the last round? If not, explain where you plan to <br />inject and provide a figure showing all of the planned injection points. <br />Are you injecting the amendment at the same strength as the last round?. If not, how will the <br />amendment be modified? <br />Do any of the recent monitoring results trigger contingency plans or indicate they may be triggered in <br />the future? <br />Are you aware of any problems that have occurred due to the previous two rounds of injections? If <br />so, describe them. <br />When are you proposing to inject? <br />We have a new General Order for In Situ Remediation (adopted in Feb 2015). If you are changing <br />anything significant from the last round of injections or anticipate multiple future injection rounds, I may <br />need to place this proposed discharge under it. <br />Marcus <br />From: Don Stevens [dstevens@ecostmanage.com ] <br />Sent: Wednesday, April 08, 2015 9:14 AM <br />To: Pierce, Marcus@Waterboards <br />Subject: CA ARNG Stockton FMS <br />Marcus, <br />This email is a follow up to the voicemail that I left you this morning, Wednesday April 8, 2015 regarding <br />the CA ARNG Stockton FMS facility.

During our planning process and budgeting process we have the following <br />questions that you may be able to answer: <br />4
