HomeMy WebLinkAbout06 - Port of Long Beach Memorandum of Agreement - Lower Bay DredgingNEWPORT CITY OF NEWPORT REACH: FERN'" City Council Staff Report Agenda Item No. 6 October 11, 2011 TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL FROM: Public Works Department Stephen G. Badum, Public Works Director 949 - 644 -3311, sbadum @newportbeachca.gov PREPARED BY: Chris Miller, Harbor Resources Manager APPROVED: --� A TITLE: Approve First Amendment to Memorandum of Agreement with the Port of Long Beach for the Lower Bay Dredging Project ABSTRACT: The Port of Long Beach ('POLB) requires an amendment to the Citys existing Memorandum of Agreement ('MOA) to dispose of the sediments from the Lower Bay Dredging Project. RECOMMENDATIONS: 1. Approve and execute the First Amendment to the Memorandum of Agreement with the POLB to dispose of the sediments from the Lower Bay Dredging Project; and 2. Authorize the City Manager or his designee to execute any future agreements related to the Lower Bay Dredging Project to ensure the City meets the strict project schedule imposed by the POLB. FUNDING REQUIREMENTS: The Lower Bay Dredging Project is estimated to cost approximately $6.4 million. Of this amount, approximately $2.2 million will be paid by the federal government, and approximately $2.5 —$3.0 million of unappropriated Tidelands funds will be contributed by the City pending Council approval in the coming months. The remaining —$1.2 million is unaccounted for at this time. DISCUSSION: The federal government has been planning to dredge Newport Harbor for many years, but because of funding issues and a disposal site for some of the unsuitable material, the project has remained on the backlog of potential projects for the Corps of Engineers ( "Corps "). 1 Approve First Amendment to Memorandum of Agreement with the Port of Long Beach for the Lower Bay Dredging Project October 11, 2011 Page 2 To help solve the problem of unsuitable material disposal, the City authorized a testing program in 2008 to assist the Corps so that the project would remain on their high priority list. The result of this testing effort was that the harbor was fully characterized, and the unsuitable material was clearly defined into manageable areas. From a funding perspective, the Corps was allocated approximately $2.2 million towards the project. Although this amount is far below the fully funded project cost of $25 million, it represents a significant step in a positive direction to dredge the Lower Bay. To help solve the problem of funding, the City sent a Letter of Intent to contribute approximately $2.5 —$3.0 million towards the project so that more dredging can occur. The Port of Long Beach Earlier this year, the Council approved an MOA with the POLB to dispose of the sediments from the Rhine Channel Contaminated Sediment Cleanup Project. This project is approximately 75% complete and the POLB is pleased with the City's performance in delivering the material on time and per their strict requirements. In order for the Corps to dredge the Lower Bay's unsuitable material however, a disposal location had to be located. In June 2011, the City formally requested that the POLB accept an additional 130,000 cubic yards of material for their Middle Harbor Project. The POLB agreed to this request, and has therefore submitted a'First Amendment to Memorandum of Agreement between the City of Newport Beach and the City of Long Beach'to be considered by Council. The major points of the amendment are: (1) the POLB is allowing the City to dispose of 130,000 cubic yards ( +, -10 %) from the Lower Bay, and (2) the Citys deadline to dispose at the POLB is March 14. 2012. ENVIRONMENTAL REVIEW: The approval of funding this activity is a'projecf for California Environmental Quality Act ('CEQA) purposes. In this case, the Army Corps of Engineers ('Corps) has prepared an Environmental Assessment ('EA) under the National Environmental Policy Act ('NEPA). CEQA authorizes the City to rely upon a NEPA document for purposes of CEQA compliance. (CEQA Guidelines, sec. 15221.) The Corps concluded through the EA that there will not be a significant adverse impact upon the existing environment or the quality of the human environment. City staff has reviewed the EA prepared by the Corps, and has determined that this document meets the requirements of CEQA. `] Approve First Amendment to Memorandum of Agreement with the Port of Long Beach for the Lower Bay Dredging Project October 11, 2011 Page 3 NOTICING: The agenda item has been noticed according to the Brown Act (72 hours in advance of the meeting at which the City Council considers the item).

DELIVERY PERIOD The delivery period for the third party material shall be as stated below. Any changes to the delivery period will be according to the provisions of the MCA. The delivery cannot commence until the City constructs the retention dike and the site Is made available. It is understood, the City has entered into a Contract with Manson /Connelly JV to construct the retention dike for the Slip 1 fill location and coordinate the deposit of Third Party materials. The retention dike is anticipated to be in place and the fill site available by August 2011. The City will notify the third party in writing when the disposal site is available. Delivery Period is August through December, 2011 plus an option at the sole discretion of City to extend this period to March 14, 2012 for additional material from other Federal Channel areas in Newport Beach. VOLUME OF MATERIAL The total volume of material the Third Party anticipates delivering to the City is up to 215,000 cubic yards, which includes 85,000 cubic yards from the Rhine Channel, 65,000 cubic yards from the Newport Channel and the West Lido Channel Area A, and 65,000 cubic yards from the other Federal Channel areas. This quantity is approximate and may vary by 10% without this memorandum needing to be revised. MATERIAL CHARACTERISTICS The materials to be delivered are generally characterized as silt /clay materials dredged from the Rhine Channel, Newport Channel, West Lido Channel Area A and other Federal Channel areas representing contaminated sediment cleanup. The material characteristics are based on geotechnical reports provided by the City of Newport Beach with the application dated June 30, 2010, additional geotechnical data dated September 2010, and the request for a revised application (attached) dated June 23, 2011. Based on the geotechnical information provided, the proposed dredge materials have the following typical geotechnical characteristics: • Mostly fine- grained soils with up to 25 percent clays (percentage of materials finer than 2 micrometers in diameter) and up to 75 percent silts [percentage of materials that are larger Exhibit A Page 1 of 2 8 than 2 micrometers in diameter and smaller than No. 200 sieve opening (75 micrometers in diameter)]. Based on early chemical information provided by the City of Newport Beach, the proposed dredge materials have the following specific characteristics: All boring locations exceed ERL and /or ERM levels for Mercury, Copper and Zinc. Also, all boring locations exceed ERL and /or ERM levels for PCBs and DDT. Any material not consistent with the general characteristics represented by the testing performed will not be permitted to be placed in the fill PLACEMENT METHODS The materials are to be delivered by barge and deposited in the Slip 1 Layer 1 area within the Middle Harbor in the Port of Long Beach as shown on the attached placement drawings. A detailed fill drawing identifying cells to deposit material into the Slip 1 will be provided. The cell arrangement will vary from week to week and Newport Beach will be required to coordinate this arrangement with other Third parties and Port contractors placing material into Slip 1. The deposited materials shall be placed in a manner as to create a relatively consistent elevation, with undulations not to exceed 4 feet vertically from the surrounding area. The material shall be placed in a pattern of barge placement that does not continuously overlap previous placement. In no case shall the material be allowed to be deposited at a height above elevation -20' MLLW. Any debris from the Third Party material disposal shall be removed by the Third Party and properly disposed of outside the Port of Long Beach. GENERAL REQUIREMENTS The Third Party shall schedule a pre - disposal coordination meeting with the City at least fourteen calendar days prior to scheduled delivery. In addition to Conditions Precedent, Section 6 of the MOA, the Third Party shall provide for the City's review and approval copies of all permits, insurance, indemnity forms no less than thirty calendar days prior to scheduled delivery in accordance with the MCA.

Per our recent conversations, the City of Newport Beach (City) has refined Its estimated dredge volume for the Rhine Channel and other City properties to be approximately 100,000 cubic yards instead of the previous estimate of 150,000 cubic yards. Separately, the Corps of Engineers has also revised its estimated volume of contaminated sediment in the harbor from approximately 700,000 cubic yard§ to around 200,000 cubic yards. Of this amount, approximately 110,000 cubic yards of contaminated material (approximately 130,000 cubic yards with OD included) has been identified as a priority for removal from the Harbor, and the City and the Corps would like to have it dredged towards the end of the year. The attached figure shows the location and quantities of material identified for priority removal. Both clean and contaminated areas are identified with the clean areas currently targeted for disposal at LA -3. The current Memorandum of Agreement (MOA) between the POLB and the City allows for disposal of 150,000 cubic yards (plus 10 %) from the Rhine Channel or a not to exceed amount of 165,000 cubic yards. The City proposes to reduce the amount of material originating from the Rhine Channel area to approximately 100,000 cubic yards and then add the remaining approximately 65,000 cubic yards from the "Newport Channel' and "West Lido Channel Area A" portions of the Federal Channel to meet the previous volume commitment of Newport material to the fill site. These areas are located Immediately to the east in the approach to the Rhine Channel. Also, if the POLB is amenable, the City and the Corps would like to bring the material from the remaining priority contaminated areas to the Middle Harbor fill site as well. This additional volume totals approximately 65,000 cubic yards (with OD included) and Includes material from the following reaches of the Federal Channel: Lido Isle Reach North, Balboa Island Channel, portions of West Lido Channel Area "A" and the area in front of the Coast Guard docks. Attached to this letter are detailed maps of each dredge area proposed for addition to the MOA as well as summary physical and chemical data to assist in the evaluation. The material is chemically similar to the Rhine Channel sediment, but slightly better quality from a geotechnical perspective. The Corps is currently preparing its internal environmental and engineering documents and plans to advertise the project on August 1 with a contractor on -board and ready to dredge by the middle of October 2011. Thus, this work would overlap with the Rhine Channel project, however, depending on the contractor selected and size of the equipment used, it may 829 Harbor Island Drive, Newport Beach, CA 92660 PIi: (949) 644 -3034 FX: (949) 723 -0589 • www. newportbeachca .gov /harborresources 13 require a little more time to place in the fill site than the current window for the Rhine Channel sediment (August 1 to December 31, 2011). The Corps feels confident that it can complete the additional work no later than February 28, 2012. In summary, what the City and the Corps are requesting at this point are the following three items: (1) A substitution of approximately 65,000 cubic yards of material from the "Newport Channel' and "West Lido Channel Area A" portions of the Federal Channel to make up the total volume of material currently identified in the City's MOA with the POLB. (2) The addition of another approximately 65,000 cubic yards of material from other Federal Channel areas for disposal into the Middle Harbor fill site. (3) An extension to the disposal window by up to 60 days for the additional Federal Channel material, if approved for disposal. The City of Newport Beach remains aggressive in its preparation for this work. The Dutra Group has already been authorized to proceed with construction and we are anticipating a start date of August 1, 2011 for the Rhine Channel dredging. As stated in the past, we are very committed to this project and are excited abqut the opportunity to work with the Port of Long Beach on this endeavor. Furthermore, the City recognizes the unique opportunity for contaminated sediment disposal afforded by the Port with the Middle Harbor fill site. Should additional opportunities for disposal become available now or in the future, and pending Council approval, the City is financially prepared to provide additional material for use In the fill. If you should have any questions or require additional information on the details of our project, please do not hesitate to contact me via phone or email. Thank you for considering our application modification.

Beach are summarized in Table 4. Data from both the Guest Docks and Interceptor Beach were compared to the PRO Residential Soil Criteria and Title 22 TTLC levels. Values that exceed the PRG are bolded and highlighted in tan All results were far below the Title 22 Total Threshold Limiting Concentrations (TTLC). Arsenic exceeded the Cal- Modified Preliminary Remediation Goal (PRG) for Residential Soils in both the composite samples from the Guest Docks and Interceptor Beach. The arsenic Cal - Modified PRG was based upon contributions from human sources. In fact, background concentrations measured in California soils are several orders of magnitude higher than the PRG value. A survey of background levels of metals in California soils (Bradford et al. 1996) indicated that the average concentration of arsenic was 3.5 mg/kg and values ranged from 0.6 to 11.0 mg/kg. The only other compounds exceeding EPA's PRG guidance for residential soils were two PAH compounds, benzo(b)fluoranthene and benzo(a)pyrene (Table 4). The concentration of benzo(b)fluomufficne in sedimenik from the Guest Docks (649 µg/kg) was comparable to the residential PRG value of 621 pg/kg. Benzo(a )pyrene in sediments from the Guest Dock composites (284 pg/kg) was over four times the PRG value of 62.1 pglkg. Table 4.
