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 ").

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.

THIRD PARTY FILL PLAN MEMO
Version 2.0 September 7, 2011
This memorandum sets forth specific details associated with the materials to be delivered by the City of
Newport Beach to the City of Long Beach.
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.

RE: REVISED APPLICATION INFORMATION FOR MIDDLE HARBOR DISPOSAL OF
FEDERAL AND CITY MATERIAL FROM LOWER NEWPORT BAY, NEWPORT BEACH,
CALIFORNIA
Dear Mr. Baldwin
On behalf of the U.S. Army Corps of Engineers, Los Angeles District (Corps), and the City of
Newport Beach, I would like to respectfully request a modification to the source and quantity of
material planned for disposal at the Middle Harbor fill site originating from Newport Harbor.
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

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.
Sincerely,
Chris Miller

51 Sediment Chemistry
The results of bulk sediment chemistry analysis of the composite samples from the Guest Docks and Interceptor .
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.
