This proposal is pursuant to the additional testing required by the Regional <br />Water Quality Control Board (RWQCB), as part of the Dredge Material Management Office <br />(DMMO) due to the high PAH results identified in the previous test results. <br /> <br />The sediment chemistry results are being fast-tracked with the intent of meeting the next <br />DMMO meeting on July 22. A breakdown of the scope of work is below. <br /> <br />Scope of Work <br /> <br />We propose the following scope of work based on our discussions. <br /> <br />1. Samolina & Testina Suooort (June 8 - June 27) <br /> <br />M&N worked with Kinnetic Laboratories Inc. and Huffman-Broadway Group to expedite test <br />results to the RWQCB, from the sampling that took place on June 8, and reach consensus <br />on the sediment test results. Based on the discussions with RWQCB and a subsequent <br />email dated June 12, additional higher resolution testing was required in Zone 9 to further <br />characterize the extent of the high PAH readings from the previous samples. Additional <br />sampling points were proposed by the project team and a figure was sent to the RWQCB <br />identifying the extent of the additional sediment cores. The plan was accepted by the <br />RWQCB and Kinnetic began testing on June 26. The effort to date, by M&N is sixteen (16) <br />hours. A figure of the approved sediment testing locations is attached. <br /> <br />2. Permittina Suooort - DMMO Meetinas & Permit Suooort <br /> <br />This effort includes the review of sediment test results prior to the DMMO meeting and <br />attendance at the DMMO meeting to discuss the sediment test results and determine the <br />possible extent of dredging in Zone 9. <br /> <br />3. Revisions to Contract Plans <br /> <br />This task includes amending the current set of contract plans to include all revisions to <br />dredge areas and disposal locations from the most recent sediment testing results.
