AGREEMENT
BETWEEN THE LOS ANGELES GATEWAY REGION INTEGRATED REGIONAL
WATER MANAGEMENT JOINT POWERS AUTHORITY
AND THE
CITY OF LYNWOOD
FOR COST SHARING FOR THE INSTALLATION OF MONITORING EQUIPMENT
AND MONITORING PURSUANT TO THE HARBOR TOXIC POLLUTANTS TMDL
This Agreement is made and entered into as of June 3, 2015, by and between
the Los Angeles Gateway Region Integrated Regional Water Management Joint Powers
Authority ( "GWMA "), a California Joint Powers Authority, and the City of Lynwood, (the
"Permittee ").
RFC'.ITAI C
WHEREAS, the mission of the GWMA includes the equitable protection and
management of water resources within its area;
WHEREAS, for the purposes of this Agreement, the term "MS4 Permittees" shall
mean those public agencies that are co- permittees to a National Pollutant Discharge
Elimination System Municipal Separate Storm Sewer System Permit Order ( "MS4
Permit ") issued by the Los Angeles Regional Water Quality Control Board;
WHEREAS, the United States Environmental Protection Agency established the
Total Maximum Daily Loads ("TMDL") for Toxic Pollutants on March 23, 2012, with the
intent of protecting and improving water quality in the Dominguez Channel and the
Greater Los Angeles and Long Beach Harbor Waters ( "Harbor Toxic Pollutants TMDL ");
WHEREAS, the Harbor Toxic Pollutants TMDL regulates certain discharges from
National Pollutant Discharge Elimination System ( "NPDES ") permit holders, requiring
organization and cooperation among the Permittees;
WHEREAS, the Permittee manages, drains or conveys storm water into at least
a portion of the Los Angeles River including the estuary or Coyote Creek or the San
Gabriel River including the estuary;
WHEREAS, various MS4 Permittees desire to facilitate the achievement of the
objectives of the Harbor Toxic Pollutants TMDL by installing one monitoring station in
the Los Angeles River at Wardlow Road, one monitoring station in the San Gabriel
River near Spring Street, and one monitoring station in the Coyote Creek, also near
Spring Street and conducting monitoring at said monitoring stations (collectively
"Monitoring Stations ") to ensure consistency with other regional monitoring programs
and usability with other TMDL related studies;
WHEREAS, installation of the Monitoring Stations and future monitoring requires
administrative coordination for the various MS4 Permittees that the GWMA can provide;
Page 1 of 10
12664/0001/1816452 -2
04/06/15
WHEREAS, individual MS4 permittees that are not GWMA members have
indicated a desire to participate in the cost sharing for the installation of the Monitoring
Stations and the costs of monitoring conducted at the Monitoring Stations (collectively
"Monitoring Costs ");
WHEREAS, the GWMA Board of Directors authorized the GWMA to enter into
individual separate agreements with such individual MS4 Permittees (which shall not
have voting rights in any group relating to the GWMA Members) for purposes of only
cost sharing in the Monitoring Costs;
WHEREAS, the members of the GWMA are the Cities of Artesia, Bell, Bell
Gardens, Bellflower, Cerritos, Commerce, Cudahy, Downey, Hawaiian Gardens,
Huntington Park, La Mirada, Lakewood, Long Beach, Lynwood, Maywood, Montebello,
Norwalk, Paramount, Pico Rivera, Santa Fe Springs, Signal Hill, South Gate, Vernon,
Whittier, Central Basin Municipal Water District and the Long Beach Water Department
( "GWMA Members ");
WHEREAS, because GWMA Members already currently pay annual membership
fees that pay for GWMA administrative costs, GWMA Members that participate in the
cost share for the Monitoring Costs shall pay a three percent (3 %) administrative fee on
each payment to cover various administrative costs;
WHEREAS, MS4 Permittees that are not GWMA Members that participate in the
cost share for the Monitoring Costs shall pay a five percent (5 %) administrative fee on
each payment to cover various administrative costs;
WHEREAS, currently a majority of MS4 Permittees tributary to the Los Angeles
and San Gabriel River systems have committed to cost share for the Monitoring Costs;
WHEREAS, because of the financial savings and benefits resulting from this
cost - sharing arrangement, other MS4 Permittees may request to participate in the cost
sharing of the Monitoring Costs;
WHEREAS, the cost -share formula, set forth in Exhibit "A" of this Agreement,
currently assumes the participation of the maximum number of MS4 Permittees required
to comply with the monitoring requirements of the Harbor Toxic Pollutants TMDL;
WHEREAS, it is currently unknown how many MS4 Permittees will ultimately
participate in the cost sharing of the Monitoring Costs;
WHEREAS, because some definite maximum cost share amount per
participating Permittee is required for planning purposes, this Agreement requires each
participating Permittee to submit an initial payment that includes the first year payment
plus a deposit that is 25% of the first year payment cost identified in Exhibit "A" of this
Agreement, to account for possible non - participation of some MS4 Permittees in the
cost share for the Monitoring Costs;
Page 2 of 10
12664/0001/1816452 -2
04/06/15
WHEREAS, depending on how many MS4 Permittees ultimately participate in
the cost sharing for the Monitoring Costs, each participating Permittee's annual cost
share amount will be adjusted and the GWMA will notify each participating Permittee of
its adjusted annual cost share amount in writing;
WHEREAS, the "Initial Payment Amount" and the "Annual Payment Amount"
identified in Section 8 ( "Financial Terms ") of this Agreement represent the maximum
dollar amounts that the Permittee is required to submit to the GWMA, but may be
reduced based on the final number of MS4 Permittees that participate in the cost
sharing for the Monitoring Costs;
WHEREAS, if the actual cost share amount is less than the Initial Payment
Amount paid by the Permittee, the GWMA will notify the Permittee and shall credit any
balance in excess of the actual cost share amount towards the Permittee's "Annual
Payment Amount" in subsequent years;
WHEREAS, the Permittee desires to share in the Monitoring Costs;
WHEREAS, the Permittee and the GWMA are collectively referred to as the
"Parties ";
WHEREAS, the Parties have determined that authorizing GWMA to hire
additional consultant as necessary to install the Monitoring Stations and conduct the
monitoring required by the Harbor Toxic Pollutants TMDL will be beneficial to the
Parties;
WHEREAS, the Permittee agrees to pay: (a) its proportional share of the
Monitoring Costs to be incurred by the GWMA in accordance with the Cost Sharing
Formula reflected in Exhibit "A ", (b) a deposit of 25% of the initial cost share amount
and a deposit of 25% of the annual cost share amount; and (c) applicable administrative
fees to cover administrative costs; and
WHEREAS, the role of the GWMA is to: (1) invoice and collect funds from the
Permittee to cover its portion of the Monitoring Costs; and (2) hire and retain
consultants to install Monitoring Stations and conduct monitoring at the Monitoring
Stations.

04/06/15
employees of the Permittee.
(b) The GWMA is solely responsible for the payment of salaries,
wages, other compensation, employment taxes, workers' compensation, or similar taxes

negligent or intentional acts, errors and omissions committed by the Permittee or its

intentional act or omission of GWMA's consultants shall be against consultants and their
insurance.
Section 11. Termination.
(a) The Permittee may terminate this Agreement for any reason, or no
reason, by giving the GWMA prior written notice thereof, but the Permittee shall remain
responsible for its entire Annual Payment Amount through the end of the current fiscal
year during which Permittee terminates the Agreement and shall not be entitled any
refund of any portion of said Annual Payment Amount. Moreover, unless the Permittee
provides written notice of termination to the GWMA by February 15th immediately prior
to the new fiscal year, the Permittee shall also be responsible for its Annual Payment
Amount through the end of the new fiscal year (e.g., If the Permittee terminates on
March 1s', 2016, the Permittee is responsible for the Annual Payment Amounts for both
FY 2015 -2016 and FY 2016 -2017. If the Permittee terminates on February 10, 2016,
the Permittee is responsible for its Annual Payment Amount only for FY 2015 -2016, not
for FY 2016 - 2017). If the Permittee terminates the Agreement, the Permittee shall
remain liable for any loss, debt, or liability otherwise incurred through the end of the new
fiscal year.
(b) The GWMA may, with a vote of the GWMA Board, terminate this
Agreement upon not less than thirty (30) days written notice to the Permittee. Any
remaining funds not due and payable or otherwise legally committed to Consultant shall
be returned to the Permittee.

Problem
The waters of Dominguez Channel and the Greater Los Angeles and Long Beach Harbor area
Statement
are impaired by heavy metals and organic pollutants. These water bodies are included on the
State's Clean Water Act 303(d) impaired waters list for one or more of the following pollutants:
cadmium, chromium, copper, mercury, lead, zinc, chlordane, dieldrin, toxaphene, DDT, PCBs,
certain PAH compounds, benthic community effects and toxicity. These impairments exist in
one or more environmental media — water, sediment, or tissue. Impairments in fish tissue are
for DDT, PCBs, toxaphene, chlordane and dieldrin.
Beneficial uses designated in these waters to protect aquatic life include the marine habitat use
(MAR) and rare, threatened or endangered species habitat use (RARE). In addition, the
estuaries (EST) are recognized as areas for spawning, reproduction and/or early development
(SPWN), migration of aquatic organisms (MIGR), and wildlife habitat (WILD). Dominguez
Channel also has an existing designated use of warm freshwater habitat (WARM) and the Los
Angeles River Estuary has the designated use of wetland habitat (WET). Beneficial uses
associated with human use of these waters include recreational use for water contact (RECD,
non - contact water recreation (REC2), industrial service supply (IND), navigation (NAV),
commercial and sport fishing (COMM), and shellfish harvesting (SHELL).
Because of the impairments, these waterbodies fail to fully support the designated beneficial
uses. The goal of this TMDL is to protect and restore fish tissue, water and sediment quality in
Dominguez Channel and Greater Los Angeles and Long Beach Harbor waters by remediating
contaminated sediment and controlling the sediment loading and accumulation of contaminated
sediment in the Harbors.
Numeric
Applicable water quality objectives for this TMDL are narrative objectives for Chemical
Targets
Constituents, Bioaccumulation, Pesticides, and Toxicity in the Basin Plan and the numeric
water quality criteria promulgated in 40 CFR section 131.38 (the California Toxics Rule
(CTR)). In addition, sediment condition objectives were determined using the State Water
Quality Control Plan for Enclosed Bays and Estuaries – Part 1 Sediment Quality (SQO Part 1)
and the sediment quality guidelines.2
The following tables provide the water, sediment and fish tissue targets for the Dominguez
Channel and Greater Los Angeles and Long Beach Harbor Waters Toxic Pollutants TMDLs.
Water Column Targets
Water targets were determined by this Basin Plan and the California Toxics Rule (CTR). Site -
specific conversion factors were developed to convert CTR acute dissolved metal criteria to
total recoverable metals using The Metals Translator Guidance for Calculating a Total
Recoverable Permit Limit From a Dissolved Criterion EPA 823 -B -96 -007.
Because exceedances of CTR criteria were only observed in freshwaters of the Dominguez
1 Dominguez Channel includes the Dominguez Channel Estuary and Torrance Lateral Channel and Greater
Los Angeles/Long Beach Harbor waters include Inner and Outer Harbor, Main Channel, Consolidated Slip,
Southwest Slip, Fish Harbor, Cabrillo Marina, Inner Cabrillo Beach, Los Angeles River Estuary, and San
Pedro Bay.

Freshwater toxicity target: This TMDL also establishes a numeric toxicity target of 1.0 toxicity
unit, chronic (1.0 TUc) to address toxicity.
TUB = Toxicity Unit, chronic = 100/NOEC (no observable effects concentration)
Targets based on new toxicity criteria that achieve the narrative Toxicity objective of Chapter 3
of this Basin Plan may substitute for the TUB of 1, when those new criteria are adopted and in
effect.
Sediment Targets
Sediment targets were determined by the narrative standards of this Basin Plan, the SQO Part 1
and the sediment quality guidelines of Long et al. (1998) and MacDonald et al. (2000), which
are recommended by the State Listing Policy. The fresh water sediment numeric targets for
Dominguez Channel are based on the freshwater Threshold Effect Concentration (TEC)
sediment guidelines compiled by the National Oceanic and Atmospheric Administration
(NOAA) in the Screening Quick Reference Tables (SQuiRTs). The marine sediment quality
guidelines of Effect Range Low (ERL), also from NOAA SQuiRTs, were used to establish the
numeric targets for marine sediment for the greater Los Angeles and Long Beach Harbor
waters. These TECs and ERLs are set as the sediment quality thresholds for the calculation of
loading capacity and allocations. This TMDL anticipates that revisions to specific sediment
quality targets may be determined by development of site - specific sediment quality values
(SQV).

n/a indicates that a fresh water sediment target is not established in this TMDL for this constituent, since
impairments for the constituent is in saltwater only.
These sediment targets are not intended to be used as `clean -up standards' for navigational,
capital. or maintenance dredging or capping activities; rather they are long -term sediment
concentrations that should be attained after reduction of external loads, targeted actions
addressing internal reservoirs of contaminants, and environmental decay of contaminants in
sediment. In addition, the categories designated in the SQO Part 1 as Unimpacted and Likely
Unimpacted by the interpretation and integration of multiple lines of evidence shall be
considered as the protective narrative objective for sediment toxicity and benthic community
effects. The thresholds established in the SQO Part 1 are based on statistical significance and
magnitude of the effect. Therefore, this TMDL implicitly includes sediment toxicity and
benthic community targets by its use of the SQO Part 1.
Fish Tissue and Associated Sediment Tareets
Fish tissue targets were determined from Fish Contaminant Goals and Advisory Tissue Levels
for Common Contaminants in California Sport Fish: Chlordane, DDTs, Dieldrin,
Methylmercury, PCBs, Selenium, and Toxaphene, developed by OEHHA (2008) to assist
agencies in developing fish tissue -based criteria for pollution mitigation or elimination and to
protect humans from consumption of contaminated fish. Associated sediment targets required
to achieve the fish tissue targets were determined from several sources depending on the
contaminant.

Channel and Greater Los Angeles and Long Beach Harbor waters.
PCBs, DDT, dieldrin, and chlordane are legacy pollutants for the most part, yet, they remain
present in the environment, bound to fine- grained particles. Because they are legacy pollutants
and are subject to environmental decay, their concentrations are gradually decreasing over time.
When these particles become waterborne, the chemicals are ferried to new locations. Urban
runoff and rainfall higher in the watersheds mobilize the particles, which are then washed into
storm drains and channels that discharge to the Dominguez Channel and greater Harbor waters.
Metals and PAHs are currently generated or deposited in the watersheds and are then washed
into storm drains and channels that discharge to the Dominguez Channel and greater Harbor
waters.
Briefly there are several categories of pollutant sources to the waters of concern in these
TMDLs. Point sources include stormwater and urban runoff (MS4) and other NPDES
discharges, including but not limited to Port operations, Terminal Island Water Reclamation
Plant (TIWRP), refineries, and generating plants. Nonpoint sources include existing
contaminated sediments and direct (air) deposition.
Dominguez Channel waters: The major point sources of organo- chlorine pesticides, PCBs,
and metals into Dominguez Channel are stormwater and urban runoff discharges. Nonpoint
sources include atmospheric deposition and fluxes from contaminated sediments into the
overlying water.
Current loads of metals into Dominguez Channel were estimated using Loading Simulation
Program in C ++ (LSPC) model output from simulated flows for 1995 -2005. Monitoring data
from NPDES discharges and land use runoff coefficients were analyzed along with Channel
stream flow rates to estimate the magnitude of metal loadings. In recognition of the wide
variety of stream flow rates generated by various rainfall conditions, flow duration curves were
utilized to analyze the metals loading during wet weather.
Greater Los Angeles and Long Beach Harbor waters: A variety of activities over the past
decades in the four contributing watersheds (Dominguez Channel, Los Angeles River, San
Gabriel River and the nearshore watershed) and in the Harbors themselves have contributed to
the sediment contamination. The contaminated sediments are a reservoir of historically
deposited pollutants. Stormwater runoff from manufacturing, military facilities, fish processing
plants, wastewater treatment plants, oil production facilities, and shipbuilding or repair yards in
both Ports discharged untreated or partially treated wastes into Harbor waters. Current
activities also contribute pollutants to Harbor sediments. In particular, stormwater runoff from
port facilities, commercial vessels (ocean going vessels and harbor craft), recreational vessels,
and the re- suspension of contaminated sediments via natural processes and/or anthropogenic
activities including (ship) propeller wash within the Ports also contributes to transport of
pollutants within the Harbors. Loadings from the four contributing watersheds are also
potential sources of metals, pesticides, PCBs, and PAHs to the Harbors.
The major nonpoint source of pesticides and PCBs to the greater Harbor waters is the current
sediments. The re- suspension of these sediments contributes to the fish tissue impairments. In
addition, atmospheric deposition may be a potential nonpoint source of metals to the watershed,
through either direct deposition or indirect deposition.

Current loading of metals, PAHs, DDT and PCBs to contaminated sediments within the
Dominguez Channel Estuary and Greater Harbor waters was estimated using monitoring data
from special studies and water body surface area for air deposition; discharge results for
refineries and TIWRP; and Environmental Fluid Dynamics Code (EFDC) model output for
2002 -2005. Model inputs included the existing average sediment concentration in the top 5 cm
of bed sediments and the total sediment deposition rate per waterbody.
Linkage
The linkage analysis connects pollutant loads to the numeric targets and protection of beneficial
Analysis
uses of Dominguez Channel and Greater Los Angeles and Long Beach Harbor waters. To
represent the linkage between source contributions and ambient water and sediment response,
two dynamic water quality models were developed to simulate source loadings and transport of
the listed pollutants in Dominguez Channel and Greater Los Angeles and Long Beach Harbor
waters. The Environmental Fluid Dynamics Code (EFDC) and Loading Simulation Program in
C ++ (LSPC) models were selected to simulate the pollutants in this TMDL.
LSPC for freshwater loadings of metals and total PAHs, DDT, and PCBs. LSPC was
developed for Dominguez Channel based on information initially provided by SCCWRP for
this watershed. In addition, Los Angeles River and San Gabriel River LSPC models were
updated from earlier TMDL models. Model development throughout the Los Angeles Region
relies on Event Mean Concentrations (EMC) as well as simulated flows to estimate pollutant
loadings. Flow data records for 1995 -2005 were used to calibrate LSPC models for each
watershed; similar simulation time frames were used to generate simulated flows for each
watershed. Dominguez Channel freshwater metals TMDLs examined only wet weather flows;
however, LSPC output for dry and wet weather conditions was applied to all estuarine and
inarine receiving waters.
The nearshore watershed was analyzed and modeled using LSPC by breaking it into 67
subwatersheds that discharge directly to the Greater Los Angeles and Long Beach Harbor
waters. These sub - watersheds were then aggregated by receiving waterbody; e.g. nearshore
contributions to Inner Harbor consisted of stormdrains and surface (sheet) flows that discharge
directly into the Inner Harbor.
The table below shows total loads from the four contributing watersheds to the Greater Harbor
waters. Overall, the Los Angeles River is the largest freshwater contributor of pollutants to the
greater Harbor waters; flows from the Los Angeles River primarily impact water quality in
eastern San Pedro Bay. The Inner Harbor receives the bulk of the loading from the nearshore
watershed.

The EFDC was used to model hydrodynamics and water and sediment quality of the greater
Los Angeles and Long Beach Harbor waters. The EFDC model applied a simulated time
period of 2002 -2005. The model was calibrated with numerous sediment monitoring studies,
including Los Angeles and Long Beach Harbor's 2006 sediment characterization study, which
yielded sediment, porewater and overlying water concentrations as well as results from highly
sensitive monitoring devices for detecting DDT, PCBs, and PAHs in the water column. The
EFDC model also considered ocean water (outside breakwater) conditions and fine and coarse
sediment transport and deposition. Ultimately the EFDC model was integrated with LSPC
output - hourly for three watersheds, daily for nearshore watersheds - to model metals, PAHs,
PCBs, and DDT (total) sediment concentrations in the receiving waters. The annual total
(clean) sediment deposition rate for the top 5 cm (active sediment layer) was multiplied by the
corresponding existing sediment pollutant level or the TMDL sediment quality target to yield
pollutant load within each waterbody.

which is dependent on watershed inputs as well as tidal movements between waterbodies, was obtained from the
EFDC model output. These values were summarized across each TMDL waterbody, resulting in the average
deposition of both sediment fines and sand by waterbody. The total deposition rate is simply the sum of the rates for
fines and sand and this value is the waterbody - specific average annual (clean) sediment deposition rate.
The EFDC model was used to evaluate several management scenarios and relative
contributions from various inputs to support water quality management decisions in Dominguez
Channel and Greater Los Angeles and Long Beach Harbor waters. Preliminary results for two
scenarios indicate that reducing freshwater input loads may not be sufficient to achieve target
concentrations in water and sediments; thus reductions in contaminant levels in bed sediments
may be required.
Loading
Loading capacity was calculated for both Dominguez Channel (wet weather) and in the
Capacity
Dominguez Channel Estuary and Greater Harbor waters (dry and wet weather).
Dominguez Channel wet weather metals TMDLs:
During wet weather, the loading capacity is a function of the volume of water in the Channel.
Given the variability in wet - weather flows, the concept of a single critical flow was not
justified. Instead, a load duration curve approach was used to establish the wet - weather loading
capacity. The load duration curve was developed by multiplying the wet - weather flows by the
in -stream numeric targets. The resulting curves identify the allowable load for a given flow.
The wet - weather TMDLs for copper and zinc are defined by these load duration curves.
Loading capacities were calculated by multiplying the daily volume by the appropriate numeric
water quality target or, in the case of lead, the observed existing average concentration. The
wet - weather loading capacity applies to any day when the maximum daily flow measured at a
location within the Dominguez Channel is equal to or greater than 62.7 cfs, which is the 901h
percentile of annual flow rates from estimated/modeled flow rates.
The freshwater toxicity TMDL is equal to 1 TUc.
Dominguez Channel Estuary and Greater Harbor waters, metals and organics in sediment
TMDLs:
Loading capacities for Dominguez Channel Estuary and Greater Harbor waters were calculated
by estimating the sediment load (based on modeled sediment deposition rates) multiplied by the
sediment quality target. The active sediment layer was defined as the top 5 cm of sediment; the
habitat of approximately 95% of benthic organisms.
In addition, chlordane, dieldrin, toxaphene and mercury TMDLs were defined for specific
waterbodies as equivalent to the concentration -based sediment quality target.
Waste Load and

dischargers), and other NDPES dischargers. Final load allocations (LAs) are assigned to direct
atmospheric deposition and bed sediments in both wet and dry weather. Dominguez Channel
freshwater allocations are set for wet weather only because exceedances have only been
observed in wet weather. Mass -based allocations have been set where sufficient data was
available to calculate mass -based allocations, otherwise, concentration -based allocations have

Interim WLA and LA are intended to not allow any decrease in current facility performance.
Interim allocations shall be met upon the effective date of the TMDL.
Interim and final WLAs and LAs shall be included in permits and/or other Board orders in
accordance with state and federal regulations and guidance.
INTERIM ALLOCATIONS
1. Dominguez Channel Freshwater Interim Allocations
A. Freshwater Toxicity Interim Allocation wet weather
An interim allocation of 2 TUc applies to each source, including all point sources assigned a
WLA and all nonpoint sources assigned a LA. The freshwater toxicity interim allocation is set
at 2 TUc based on current monitoring results performed by the Los Angeles County
Department of Public Works, which have shown average values of less than 2 TUc. The fresh
water interim allocation shall be implemented as a trigger requiring initiation and
implementation of the TRE/TIE process as outlined in US EPA's "Understanding and
Accounting for Method Variability in Whole Effluent Toxicity Applications Under the National
Pollutant Discharge Elimination System Program" (2000) and current NPDES permits. The
fresh water interim allocation shall be implemented in accordance with US EPA, State Board
and Regional Board resolutions, guidance and policy at the time of permit issuance,
modification or renewal.
B. Freshwater Metals Interim Allocations - wet weather only
Interim water allocations are assigned to stormwater dischargers (MS4, Caltrans, general
construction and general industrial stormwater dischargers) and other NPDES dischargers.
Interim water allocations are based on the 95`h percentile of total metals data collected from
January 2006 to January 2010 using a log - normal distribution. The use of 95'" percentile values
to develop interim allocations is consistent with NPDES permitting methodology. Regardless of
the interim allocations below, permitted dischargers shall ensure that effluent concentrations
and mass discharges do not exceed levels that can be attained by performance of the facility's
treatment technologies existing at the time of permit issuance, reissuance or modification.

Non -MS4 point sources such as General Construction, General Industrial, individual industrial
permittees, including power generating stations, minor permits and irregular dischargers into
Dominguez Channel Estuary and Greater Harbor Waters are assigned concentration -based
allocations. Mass -based WLA for other refineries based on appropriate data maybe considered
during the TMDL reconsideration. (Refineries which have provided discharge flow data along
with monitoring results are assigned mass -based allocations, whereas other refineries are
assigned concentration -based allocations because no discharge flow data has been provided.)
Any future minor NPDES permits or enrollees under a general NPDES permit are also assigned
the concentration -based waste load allocations. The allocations are set equal to the saltwater
targets for metals and equal to the human health targets for the organic compounds in CTR.
The averaging period for the concentration -based WLAs shall be consistent with that specified
in the regulation establishing the criterion or objective or relevant implementation guidance

Pyrene of 11,000 pg/L is assigned as an individual WLA to Pyrene. Other PAH compounds in the CTR shall be
screened as part of the TMDL monitoring.
A. Mass -based allocations for metals and PAHs compounds
Mass -based WLAs are assigned to the Terminal Island Water Reclamation Plant (TfWRP)
(based on current discharge volume) and other point sources that have sufficient discharge flow
data. Municipal stormwater sources, including the Los Angeles, Long Beach, Caltrans and
other MS4 co- permittees, are assigned a mass -based allocation for each permit in place at the
time of TMDL adoption, depending on the waterbody. Discharges from the Port of Los
Angeles (POLA) and Port of Long Beach (POLB) are grouped with the MS4 dischargers.
Mass -based WLAs are applied as annual limits. Individual mass -based WLAs for an individual
MS4 Permittee will be calculated based on its share, on an area basis, of the mass -based WLA or other
approved approach available at the time final mass -based WLAs are in effect and incorporated into the
permit. TMDLs and allocations were developed based on existing sediment concentrations in
the active sediment layer defined herein as the top 5 cm of bed sediment concentrations.
Load Allocations are assigned to existing sediments and direct air deposition. All allocations
assigned to point sources and non -point sources are subtracted from the loading capacity and
the remaining allocatable amount is assigned to the bed sediments. Direct air deposition
allocations have been set equal to existing load estimates for Cu, Zn and PAHs based on
atmospheric monitoring results collected in 2006. The Pb air deposition allocation has been
developed by using the SCAQMD air quality Pb criteria (2010) multiplied by the surface area
of each waterbody to produce direct air deposition allocations. Future changes to Cu, Zn and
PAH air quality criteria, other regulation such as brake pad requirements, or other improvement
in air quality may allow for re- calculations of air deposition allocations in future revisions to
the TMDL. If, at some point in the future, a nonpoint source is considered subject to NPDES or
WDR regulations, then the corresponding load allocation established herein may be considered
a waste load allocation for purposes of implementation and enforcement through a permit or
other Board order.
Air deposition allocations for copper and zinc are based on existing loads; by assuming no
direct deposition reductions, this consumes or partially consumes the available loading
capacity. As a result, copper and zinc load allocations for bed sediments are negative values, in
Inner and Outer Harbor, indicating that copper and zinc loads must be reduced. (Each negative
copper and zinc bed sediment allocation may alternatively be interpreted as zero, or not
adversely affecting benthic organisms.) The amount of copper and zinc load reduction may be
revised based on future monitoring results. If future air deposition studies show lower existing
air deposition copper and zinc loads, or if future copper and zinc sediment characterization
studies show lower bed sediment copper and zinc loads, then copper and zinc allocations may
be adjusted.
The bed sediment LA is assigned to the City of Los Angeles (including the Port of Los
Angeles), the City of Long Beach (including the Port of Long Beach) and the State Lands
Commission. After remediation activities that address existing sediment contamination are
complete and when LAs are attained, if bed sediments are recontaminated as a result of
continued polluted discharge from the surrounding watersheds, the WLA compliance
monitoring data will be used, along with other available information, to assess the relative
contribution of watershed dischargers and determine their responsibility and allocations for
secondary remediation activities.

Consolidated Slip and Fish Harbor are impaired for mercury in sediments and the average
sediment concentration (1.1 mg/kg dry) is significantly higher than the target concentration
(0.15 mg/kg dry). Consolidated Slip and Dominguez Channel Estuary are impaired for
cadmium in sediments, and Consolidated Slip is also impaired for chromium in sediments.

Concentration -based Sediment WLAs (m dry sediment)
Mercury applies to both Consolidated Slip and Fish Harbor; Cd applies to Dominguez Channel Estuary
and Consolidated Slip, and Cr applies to Consolidated Slip only.
Compliance with these sediment TMDLs for Cu, Pb, Zn, Cd, Cr, Hg and total PAHs may be
demonstrated via any one of three different means:
a. Final sediment allocations, as presented above, are met.
b. The qualitative sediment condition of Unimpacted or Likely Unimpacted via the
interpretation and integration of multiple lines of evidence as defined in the SQO Part
1, is met, with the exception of Cr, which is not included in the SQO Part 1.
c. Sediment numeric targets are met in bed sediments over a three -year averaging period.
Compliance with mass -based WLAs shall be measured at designated discharge points.
Compliance with concentration -based WLAs for existing sediment shall be determined by
pollutant concentrations in ambient sediment in each waterbody. The average ambient bulk
sediment level within a waterbody at or below the sediment quality target is considered
compliance with these TMDLs.

Fish tissue levels of certain bioaccumulative compounds are above desired numeric targets.
These TMDLs are designed to reduce contaminated sediment levels, which will result in lower
corresponding pollutant levels in fish tissue. These sediment allocations have been derived to
support lowering fish tissue levels using biota - sediment accumulation factors (BSAFs) or
ERLs, whichever is more protective. For chlordane and dieldrin, the ERL values are lower and
more protective than BSAF values. The DDT sediment values are comparable (ERL = 1.58,
BSAF = 1.9); the more stringent one was used for calculation. The PCBs sediment value
associated with fish tissue is more stringent than the ERL sediment value for PCBs.
Mass -based WLAs are assigned for TIWRP and other point sources that have sufficient
discharge flow data. Municipal stormwater sources, including the Los Angeles, Long Beach,
Caltrans and other MS4 co- permittees, are assigned a single, mass -based allocation by permit,
depending on the waterbody. Discharges from the Port of Los Angeles (POLA) and Port of
Long Beach (POLB) are grouped with the MS4 dischargers. Mass -based WLAs are applied as
annual limits.
Individual mass -based WLAs for an individual MS4 Permittee will be calculated based on its
share, on an area basis, of the mass based WLA or other approved approach available at the time final
mass -based WLAs are in effect and incorporated into the pen-nit. Mass -based LAs are identified for
bed sediments and direct air deposition. Direct air deposition allocations for total DDT are
based on estimates of existing loads using atmospheric monitoring results collected close to Los
Angeles/Long Beach Harbor at SCAQMD Wilmington Station in 2006. Pollutant - specific air
deposition values (DDT = 29 ng/m2 /day) were multiplied by the surface area of each
waterbody to produce direct deposition allocations. Direct deposition allocations for PCBs are
not included since air deposition has been measured to be less than water -to -air fluxes.
DDT load allocations for bed sediments are negative values, with the exception of those for the
Los Angeles River Estuary, indicating that DDT loads must be reduced. (Each negative DDT
bed sediment allocation may alternatively be interpreted as zero, or interpreted as minimal
bioaccumulation into the food web.) The amount of DDT load reduction may be revised based
on future monitoring results. If future air deposition studies show lower existing air deposition
DDT loads, or if future DDT sediment characterization studies show lower bed sediment DDT
loads, then DDT load allocations may be adjusted.
The Greater Harbor Waters (excluding LA River Estuary and Consolidated Slip) bed sediment
LA is assigned to the City of Los Angeles (including the Port of Los Angeles), the City of Long
Beach (including the Port of Long Beach) and the State Lands Commission. After remediation
activities that address existing sediment contamination are complete and when LAs are attained,
if bed sediments are recontaminated as a result of continued polluted discharge from the
surrounding watersheds, the WLA compliance monitoring data will be used, along with other
available information, to assess the relative contribution of watershed dischargers and
determine their responsibility and allocations for secondary remediation activities.
DDT and PCBs (total) TMDLs apply to all estuarine and marine waters in Greater Harbor area,
including Inner Cabrillo Beach, Los Angeles River Estuary and Eastern San Pedro Bay.

3. Diazinon
Los Angeles County monitoring data in Dominguez Channel freshwaters show diazinon
exceedences from 2002 -2005, but none from 2006 -2010. This timing is concurrent with EPA's
ban on urban use of diazinon, effective Dec. 31, 2005. Based these results, no diazinon TMDLs
are developed at this time.
Margin of
The Dominguez Channel freshwater allocations included an explicit margin of safety (MOS)
Safety
equal to 10% of the loading capacity or existing load to account for any additional uncertainty
in the wet - weather TMDLs. The 10% MOS was subtracted from the loading capacity or
existing load, whichever was smaller. Applying an explicit margin of safety is reasonable
because a number of uncertain estimates are offset by the explicit margin of safety. While the
observed dissolved -to -total metals ratios are not similar to CTR default conversion values, there
appears to be very poor correlation between the fraction of particulate metals and TSS. Also,
there is added uncertainty regarding stream flow rates during wet weather conditions, when the
highest metal loads occur, thus an explicit margin of safety is justified.
An implicit margin of safety exists in the final allocations to Dominguez Channel Estuary and
Greater Harbor waters. The implicit margin of safety is based on the selection of multiple
numeric targets, including targets for water, fish tissue and sediment among other conservative
modeling assumptions. An additional explicit margin of safety must be considered and may be
applied if any chemical- specific sediment quality target is revised or updated contingent on
future sediment quality studies. That is, there may be uncertainty associated with revised
sediment quality values, which may warrant including an additional explicit margin of safety.
Seasonal
Wet weather events may produce extensive sediment redistribution and transport sediments to
Variations and
the harbors and the CTR -based water column targets are protective of this condition. This
Critical
would be considered the critical condition for loading.
Conditions
No correlation with flow or seasonality (wet vs. dry season) was found to exist in sediment or
tissue data. Given that allocations for this TMDL are expressed in terms pesticides, PCBs,
PAHs, and metals concentrations in sediment, a critical condition is not identified based upon
flow or seasonality.
Because the adverse effects of pesticides, PCBs, PAHs, and metals are related to sediment
accumulation and bioaccumulation in the food chain over long periods of time, short term
variations in concentrations are less likely to cause significant impacts upon beneficial uses.
Monitoring
Monitoring by assigned responsible parties is required in three waterbody areas:
Plan
1. Dominguez Channel, Torrance Lateral, and Dominguez Channel Estuary
2. Greater Los Angeles and Long Beach Harbor Waters (including Consolidated Slip)
3. Los Angeles River and San Gabriel River
Monitoring shall be conducted under technically appropriate Monitoring and Reporting Plans
(MRPs) and Quality Assurance Project Plans (QAPPs). The MRPs shall include a requirement
that the responsible parties report compliance and non - compliance with waste load and load
allocations as part of annual reports submitted to the Regional Board. The QAPPs shall include
protocols for sample collection, standard analytical procedures, and laboratory certification.
All samples shall be collected in accordance with SWAMP protocols. Monitoring Plans shall
be submitted twenty (20) months after the effective date of the TMDL for public review and,
-22- May 5, 2011
Attachment A to Resolution No. Rll -008
TMDL Element I Regulatory Provisions
subsequently, Executive Officer approval.
Monitoring shall begin six months after the monitoring plan is approved by the Executive
Officer. Responsible parties assigned both WLAs and LAs may submit one document that
addresses the monitoring requirements (as described below) and implementation activities for
both WLAs and LAs. Responsible parties shall submit annual monitoring reports.
The Regional Board Executive Officer may reduce, increase, or modify monitoring and
reporting requirements, as necessary, based on the results of the TMDL monitoring program.
Currently, several of the constituents of concern have numeric targets that are lower than the
readily available detection limits. As analytical methods and detection limits continue to
improve (i.e., development of lower detection limits) and become more environmentally
relevant, responsible parties shall incorporate new method detection limits in the MRP and
QAPP.
Dominguez Channel, Torrance Lateral, and Dominguez Channel Estuary Compliance
Monitoring Program
For Dominguez Channel, Dominguez Channel Estuary, and Torrance Lateral, water and
total suspended solids samples shall be collected at the outlet of the storm drains
discharging to the channel and the estuary. Fish tissue samples shall be collected in
receiving waters of the Dominguez Channel Estuary. Sediment samples shall also be
collected in the estuary.
� Water Column Monitoring
Water samples and total suspended solids samples shall be collected during two wet
weather events and one dry weather event each year. The first large storm event of the
season shall be included as one of the wet weather monitoring events. Water samples and
total suspended solid samples shall be analyzed for a suite of compounds including, at a
minimum, metals, including lead, zinc, and copper, DDT, PCBs, Benzo[a] anthrancene,
Benzo[a]pyrene, Chrysene, Phenanthrene, and Pyrene. Sampling shall be designed to
collected sufficient volumes of suspended solids to allow for analysis of the pollutants in
the bulk sediment.
In addition to TMDL constituents, general water chemistry (temperature, dissolved
oxygen, pH, and electrical conductivity) and a flow measurement will be required at each
sampling event. General chemistry measurements may be taken in the laboratory
immediately following sample collection, if auto samplers are used for sample collection
or if weather conditions are unsuitable for field measurements. In addition, toxicity shall
be tested for in the freshwater portion of Dominguez Channel.
• Sediment Monitoring
A sediment monitoring program shall be developed consistent with the selected method for
compliance and all samples shall be collected in accordance with SWAMP protocols.
a) If compliance will be determined based on achieving sediment quality targets, sediment
chemistry samples shall be collected every two years for analysis of general sediment
quality constituents and the full chemical suite as specified in SQO Part 1. In addition,
benthic community effects shall be assessed in the Dominguez Channel Estuary.
-23- May 5, 2011
Attachment A to Resolution No. Rll -008
TMDL Element I Regulatory Provisions
b) If compliance will be determined based on the SQO compliance method, sediment
chemistry samples shall also be collected every five years (in addition to, and in
between, the sediment triad sampling events as described below), beginning after the
first sediment triad event, to evaluate trends in general sediment quality constituents
and listed constituents relative to sediment quality targets. Chemistry data without
accompanying sediment triad data shall be used to assess sediment chemistry trends and
shall not be used to determine compliance.
Sediment quality objective evaluation as detailed in the SQO Part 1 (sediment triad
sampling) shall be performed every five years in coordination with the Biological Baseline
and Bight regional monitoring programs, if possible. Sampling and analysis for the full
chemical suite, two toxicity tests and four benthic indices as specified in SQO Part 1 shall
be conducted and evaluated. If moderate toxicity as defined in the SQO Part 1 is
observed, results shall be highlighted in annual reports and further analysis and evaluation
to determine causes and remedies shall be required in accordance with the EO approved
monitoring plan. Locations for sediment triad assessment and the methodology for
combining results from sampling locations to determine sediment conditions shall be
specified in the MRP to be approved by the Executive Officer. The sampling design shall
be in compliance with the SQO Part 1 Sediment Monitoring section (VII.E.).
Fish Tissue Monitoring
Fish tissue samples shall be collected every two years from the Dominguez Channel
Estuary and analyzed for chlordane, dieldrin, toxaphene, DDT, and PCBs. The target
species in the Dominguez Channel Estuary shall be selected based on residency, local
abundance and fish size at the time of field collection. Tissues analyzed shall be based on
the most common preparation for the selected fish species.
The Dominguez Channel responsible parties are each individually responsible for conducting
water, sediment, and fish tissue monitoring. However, they are encouraged to collaborate or
coordinate their efforts to avoid duplication and reduce associated costs. Dischargers
interested in coordinated monitoring shall submit a coordinated MRP that identifies
monitoring to be implemented by the responsible parties. Under the coordinated monitoring
option, the compliance point for the stormwater WLAs shall be storm drain outfalls or a
point(s) in the receiving water that suitably represents the combined discharge of cooperating
parties.
The details of the monitoring program including sampling locations and all methods shall be
specified in the MRP to be approved by the Executive Officer.
2. Greater Los Angeles and Long Beach Harbor Waters Compliance Monitoring Program
At a minimum, compliance monitoring shall be conducted at the locations and for the
constituents listed in the table below for water column, total suspended solids, and sediment.
The exact locations of monitoring sites shall be specified in the MRP to be approved by the
Executive Officer. During aspects of the remedial action(s) for the Montrose Superfund Site
that may mobilize sediments and associated pollutants from the on- or near- property soils or
"Neighborhood Areas ", it is recommended that US EPA, as the regulatory oversight agency,
require that Potentially Responsible Parties (PRP) implement monitoring to evaluate pollutant
loads and concentrations leaving the site and surrounding area, as well as pollutant

concentrations in the bed sediments of Dominguez Channel Estuary and Consolidated Slip and
coordinate such monitoring with other TMDL compliance monitoring.
• Water Column Monitoring
Water samples and total suspended solids samples shall be collected during two wet
weather events and one dry weather event each year. TSS shall be collected at several
depths during wet weather events. The first large storm event of the season shall be
included as one of the wet weather monitoring events. General water chemistry
(temperature, dissolved oxygen, pH, and salinity) and a flow measurement shall be
required at each sampling event.
Sediment Monitoring
Sediment chemistry samples shall be collected every five years (in addition to, and in
between, the sediment triad sampling events as described below), beginning after the first
sediment triad event, to evaluate trends in general sediment quality constituents and listed
constituents relative to sediment quality targets. Chemistry data without accompanying
sediment triad data shall be used to assess sediment chemistry trends and shall not be used
to determine compliance.

3. Los Angeles River and San Gabriel River Compliance Monitoring Program
Los Angeles River Watershed and San Gabriel River Watershed responsible parties identified
in effective metals TMDLs for Los Angeles River and San Gabriel River are responsible for
conducting water and sediment monitoring above the Los Angeles River Estuary and at the
mouth of the San Gabriel River, respectively, to determine the Rivers' contribution to the
impairments in the Greater Harbor waters.
Water Column Monitoring
Water samples and total suspended solids samples shall be collected at, at least one site
during two wet weather events and one dry weather event each year. The first large storm
event of the season shall be included as one of the wet weather monitoring events. Water
samples and total suspended solid samples shall be analyzed for metals, DDT, PCBs, and
PAHs. Sampling shall be designed to collect sufficient volumes of suspended solids to
allow for analysis of the listed pollutants in the bulk sediment.
General water chemistry (temperature, dissolved oxygen, pH, and electrical conductivity)
and a flow measurement shall be required at each sampling event. General chemistry
measurements may be taken in the laboratory immediately following sample collection if
auto samplers are used for sample collection or if weather conditions are unsuitable for
field measurements.
• Sediment Monitoring
For sediment chemistry, sediment samples shall be collected at, at least one site every two
years for analysis of general sediment quality constituents and the full chemical suite as
specified in SQO Part 1. All samples shall be collected in accordance with SWAMP
protocols.
The details of the monitoring program including sampling locations and all methods shall
be specified in the MRP to be approved by the Executive Officer.
-27- May 5, 2011
Attachment A to Resolution No. Rll -008
Implementation The regulatory mechanisms to implement the TMDL include, but are not limited to, general
Plan NPDES permits, individual NPDES permits, MS4 Permits covering jurisdictions and flood
control districts within these waters, the Statewide Industrial Storm Water General Permit, the
Statewide Construction Activity Storm Water General Permit, the Statewide Stormwater Permit
for Caltrans Activities, and the authority contained in Sections 13263, 13267 and 13383 of the
Cal. Water Code. For each discharger assigned a WLA, the appropriate Regional Board Order
shall be reopened or amended when the order is reissued, in accordance with applicable laws, to
incorporate the applicable WLA(s) as a permit requirement consistent with federal regulation
and related guidance (40 CFR 144.22(d)(1)(vii)(B); US EPA Memorandum "Revisions to the
November 22, 2002 Memorandum `Establishing Total Maximum Daily Load (TMDL)
Wasteload Allocations (WLAs) for Storm Water Sources and NPDES Permit Requirements
Based on Those WLAs "' (November 12, 2010)). LAs will be implemented in a manner
consistent with federal and state laws, regulations and policies, including the Nonpoint Source
Implementation and Enforcement Policy.
Implementation by assigned responsible parties is required in three waterbody areas:
1. Dominguez Channel, Torrance Lateral, and Dominguez Channel Estuary
2. Greater Los Angeles and Long Beach Harbor waters (including Consolidated Slip)
3. Los Angeles River and San Gabriel River
Actions to achieve WLA and LA may be implemented in phases with information from each
phase being used to inform the implementation of the next phase. These sediment targets are not
intended to be used as `clean-up standards' for navigational, capital or maintenance dredging or
capping activities; rather they are long -term sediment concentrations that should be attained
after reduction of external loads, targeted actions addressing internal reservoirs of contaminants,
and environmental decay of contaminants in sediment. The implementation may be adjusted, as
necessary, based on information gained during each phase. Table 7-40.2 contains the schedule
for responsible parties to develop and implement TMDL implementation plans and sediment
management plans to comply with the TMDL.
1. Dominguez Channel, Torrance Lateral, and Dominguez Channel Estuary
Responsible parties can implement a variety of implementation strategies to meet the required
WLAs and LAs, such as non - structural and structural BMPs, diversion and treatment to reduce
sediment transport from the watershed to Dominguez Channel and Greater Harbor waters, and
sediment removal activities.
Nonpoint source elements include legacy sediments and air deposition across Dominguez
Channel and Harbor waters. The responsible parties identified in the Allocation section and in
part 6. Application of Allocations to Responsible Parties of this section are assigned sediment
load allocations and responsibility for remediation of the contaminated sediments to attain the
load allocations.
■ Phase I
The purpose of the Phase I implementation is to reduce the amount of sediment transport
from point sources that directly or indirectly discharge to Dominguez Channel and the
Harbor waters. Phase I should include watershed -wide implementation actions. Important
components of Phase I should be to secure the relationships and agreements between
cooperating parties and to develop a detailed scope of work with priorities.
-28- May 5, 2011
Attachment A to Resolution No. Rll -008
Potential watershed -wide non - structural BMPs include more frequent and appropriately
timed storm drain catch basin cleaning, improved street cleaning by upgrading to vacuum
type sweepers, and educating residents and industries about good housekeeping practices.
Structural BMPs may include the placement of stormwater treatment devices designed to
reduce sediment loading, such as infiltration trenches, vegetated swales, and/or filter strips
at critical points in the watershed. Structural BMPs may also include diversion and
treatment facilities to divert runoff directly, or provide capture and storage of runoff and
then diversion to a location for treatment. Treatment options to reduce sediment could
include sand or media filters.
The Los Angeles County Flood Control District (District) owns and operates Dominguez
Channel; therefore, the District and the cities that discharge to Dominguez Channel shall
each be responsible for conducting implementation actions to address contaminated
sediments in Dominguez Channel. Responsible parties in Dominguez Channel shall
develop a Sediment Management Plan to address contaminated sediment in Dominguez
Channel and Dominguez Channel Estuary.
Sediment conditions shall be evaluated through the Sediment Quality Objective (SQO)
process detailed in the SQO Part 1. If chemicals within sediments are contributing to an
impaired benthic community or toxicity, then causative agent(s) shall be determined using
SQO recommended procedures, SQO Part 1 (VII.F.). Impacted sediments shall be included
in the list of sites to be managed.
■ Phase H
Phase II should include the implementation of additional BMPs and site remedial actions, as
determined to be effective based on the success of upstream source control, evaluation of
TMDL monitoring data collected during Phase I, and targeted source reduction activities as
identified in Phase I. Regional responsible parties should develop, prioritize, and
implement Phase II elements based on data from the TMDL monitoring program and other
available information from special studies. Possible actions include implementation of
additional structural and non - structural BMPs throughout the watershed by municipalities,
LA County, Caltrans, and others. Phase H should include the implementation of site -
specific cleanup actions for areas identified as high priority in the Dominguez Channel
Estuary and in accordance with the Sediment Management Plan.
As management actions are planned for a contaminated site, site - specific cleanup
criteria should be determined following protocols that are consistent with state
and national guidance. The site improvements should be confirmed through a
sediment monitoring program.
There are two Superfund sites located within Dominguez Channel Watershed: the
Montrose Superfund Site and the Del Amo Superfund Site. The US EPA has not
yet reached a final remedial decision with respect to certain of the Montrose
Superfund Site Operable Units (OUs) that remain contaminated with DDT,
including the on- and near- property soils (OU1), the current storm water pathway
(OU2), and the "Neighborhood Areas" (OU4 and OU6). The TMDL, its waste
load and load allocations, and other regulatory provisions of this TMDL may be
applicable or relevant and appropriate requirements (ARARs) as set forth in
Section 121(d) of the Comprehensive Environmental Response, Compensation,
and Liability Act (42 U.S.C. §§ 9621(d)) for those OUs. Whether provisions
within the TMDL are ARARs will be determined in accordance with CERCLA
-29- May 5, 2011
Attachment A to Resolution No. Rll -008
when US EPA develops Records of Decision for the Superfund sites. The TMDL
for DDT should be taken into account in the course of the remedial decision -
making process. The City of Los Angeles and/or Los Angeles County, should
they decide to take action that impacts one of the OUs, shall consult with US
EPA's Superfund Division in advance of such action. Detection of DDT
compounds in water or sediment samples collected within Torrance Lateral shall
trigger additional monitoring, by parties to be determined by the Executive
Officer, in coordination with EPA, to evaluate potential contribution from
contaminated soils related to upstream Montrose operable units discharging via
the Kenwood storm drain. Upon reconsideration of the TMDL, all monitoring
results for DDT compounds collected by responsible parties or other entities shall
be considered as part of source analysis and to determine potential future
allocation(s) that may be necessary to minimize impacts to downstream waters
and restore beneficial uses in TMDL waterbodies.
■ Phase III
Phase III should include implementation of secondary and additional remediation actions as
necessary to be in compliance with final allocations by the end of the implementation
period. TMDLs to allocate additional contaminant loads between dischargers in the
Dominguez Channel, Torrance Lateral and Dominguez Channel Estuary subwatersheds
may also be developed, if necessary.
2. Greater Los Angeles and Long Beach Harbor Waters (including Consolidated Slip)
Responsible parties can implement a variety of implementation strategies to meet the required
WLAs, such as non - structural and structural BMPs, and/or diversion and treatment to reduce
sediment transport from the nearshore watershed to the Greater Harbor waters.
■ Phase I
The purpose of Phase I implementation is to reduce the amount of sediment transport from
point sources that directly or indirectly discharge to the Harbor waters. Phase I should
include actions to be implemented throughout the nearshore watershed and specific
implementation actions at the Ports. Important components of Phase I should be to secure
the relationships and agreements between cooperating parties and to develop a detailed
scope of work with priorities.
Potential watershed -wide non - structural BMPs include more frequent and appropriately
timed storm drain catch basin cleaning, improved street cleaning by upgrading to vacuum
type sweepers, and educating residents and industries about good housekeeping practices.
Structural BMPs may include the placement of stormwater treatment devices designed to
reduce sediment loading, such as infiltration trenches, vegetated swales, and/or filter strips
at critical points in the watershed. Structural BMPs may also include diversion and
treatment facilities to divert runoff directly, or provide capture and storage of runoff and
then diversion to a location for treatment. Treatment options to reduce sediment could
include sand or media filters.
Implementation actions at the Ports should be developed to address different sources that
contribute loading to the Harbors such as Port-wide activities and associated control
measures for water and sediment, control measures to reduce the discharges from various
-30- May 5, 2011
Attachment A to Resolution No. Rll -008
land uses in the Harbors, nearshore discharges, and on -water discharges. The
implementation actions described in the Water Resources Action Plan (WRAP) adopted by
the Port of Los Angeles and the Port of Long Beach represent a range of activities that
could be conducted to control discharges of polluted stormwater and contaminated
sediments to the Harbors.
To meet necessary reductions in sediment bed loads, a Sediment Management Plan shall be
developed by the dischargers assigned a sediment bed load LA, the Cities of Los Angeles
and Long Beach and the State Lands Commission. Phase I implementation elements for the
improvement of the Harbors' sediment quality should be conducted through the
continuation of source reduction, source control, and sediment management. Below are
proposed implementations actions that may be implemented in Phase I to improve sediment
quality at the ports:
- Removal of Contaminated Sediment within Areas of Known Concern. Planned
removal programs are in place for IR Site 7 (former Navy facility in the Port of Long
Beach) and Berth 240 (former Southwest Marine facility in the Port of Los Angeles).
Contaminated sediment will be removed by Port of Long Beach and Port of Los
Angeles.
Sediment Management Plan, Prioritization Assessment for Contaminated Sediment
Management. Sediment will be evaluated through the Sediment Quality Objective
(SQO) process detailed in the Enclosed Bays and Estuaries Plan (i.e., SQO Part 1 as
amended). If chemicals within sediments are contributing to an impaired benthic
community or toxicity, or fish tissue, then causative agent(s) will be determined using
SQO recommended procedures, including SQO Part I (VII. F.). Impacted sediments
will be included in the list of sites to be managed. The sites to be managed by the
responsible parties will be prioritized for management and coupled with other planned
projects when feasible. Prioritized sites shall include known hot spots, including but
not limited to Consolidated Slip and Fish Harbor. For these prioritized sites, the
sediment management plan shall include concrete actions and milestones, including
numeric estimates of load reductions or removal, to remediate these priority areas and
shall demonstrate that actions to address prioritized hot spots will be initiated and
completed as early as possible during the 20 -year TMDL implementation period. This
process will prioritize management efforts on sites that have the greatest impact to the
overall health of the benthic community and fish tissue, and allow sites with lower
risks to be addressed in later phases when opportunities can be coupled to capital
projects. As management actions are planned for a contaminated site, site - specific
cleanup criteria will be determined following established protocols that are consistent
with state and national policy and guidance. The site will then be managed and the
improvements confirmed through a sediment monitoring program.
Superfund Sites. Two Superfund sites are located in Dominguez Channel Watershed:
the Montrose Superfund Site (DDT) and the Del Amo Superfund Site (benzene).
Montrose Superfund Site includes multiple operable units (OUs), which are identified
as investigation areas potentially containing site - related contamination. These
Superfund Sites are located in a community known as Harbor Gateway, which is
situated mostly in the City of Los Angeles and partially in unincorporated land in Los
Angeles County. Harbor Gateway lies within the Kenwood Drain subwatershed, which
discharges stormwater into Torrance Lateral which flows downstream into saline
waters of Dominguez Channel Estuary and Consolidated Slip. The Torrance Lateral,
-31 - May 5, 2011
Attachment A to Resolution No. Rll -008
Dominguez Channel Estuary and Consolidated Slip (OU2) contain sediments
contaminated with multiple pollutants including DDT (potentially from various
sources). The US Environmental Protection Agency (US EPA) has been working with
other government agencies and local agencies including the City of Los Angeles and
Los Angeles County to ensure the protection of both the environment and public
health in the areas surrounding these Superfund sites.
In August 1999, USEPA and the State of California, which includes the Regional
Board, entered into a consent decree concerning the Montrose Superfund site in a case
entitled United States of America and State of California versus Montrose Chemical
Corporation of California, et al., United States District Court Central District of
California, Case No. CV 90- 3122 -AAH (JRx).
The US EPA has not yet reached a final remedial decision with respect to certain of
the Montrose Superfund Site Operable Units (OUs) that remain contaminated with
DDT, including the on- and near- property soils (OU1), the current storm water
pathway (OU2), and the "Neighborhood Areas" (OU4 and OU6). The TMDL, its
waste load and load allocations, and other regulatory provisions of this TMDL may be
applicable or relevant and appropriate requirements (ARARs) as set forth in Section
121(d) of the Comprehensive Environmental Response, Compensation, and Liability
Act (42 U.S.C. §§ 9621(d)) for those OUs. Whether provisions within the TMDL are
ARARs will be determined in accordance with CERCLA when USEPA develops
Records of Decision for the Superfund sites. The TMDL for DDT should be taken into
account in the course of the remedial decision - making process. US EPA Superfund
does not need to make a remedial decision prior to individual or collective action (by
City of LA and/or County of LA) to clean up sediments within the OU2 pathway. The
City of Los Angeles and/or Los Angeles County, should they decide to take action that
impacts one of the OUs, shall consult with US EPA's Superfund Division in advance
of such action. The goal of consultation is to ensure the proposed sediment cleanup
will not aggravate the situation or further interfere with the OU2 site. Detection of
DDT compounds in water or sediment samples collected within Torrance Lateral shall
trigger additional monitoring, by parties to be determined by the Executive Officer, in
coordination with EPA, to evaluate potential contribution from contaminated soils
related to upstream Montrose operable units discharging via the Kenwood storm drain.
Upon reconsideration of the TMDL, all monitoring results for DDT compounds
collected by responsible parties or other entities shall be considered as part of source
analysis and to determine potential future allocation(s) that may be necessary to
minimize impacts to downstream waters and restore beneficial uses in TMDL
waterbodies.
■ Phase II
Phase II should include the implementation of additional BMPs and site remedial actions in
the nearshore watershed and in the Harbors, as determined to be effective based on the
success of upstream source control, TMDL monitoring data evaluations, WRAP activities
implemented during Phase I, and targeted source reduction activities as identified in Phase
I. Responsible parties should develop, prioritize, and implement Phase H elements based on
data from the TMDL monitoring program and other available information from special
studies. Possible actions include additional structural and non - structural BMPs throughout
the watershed.
-32- May 5, 2011
Attachment A to Resolution No. Rll -008
Phase II should include the implementation of site - specific cleanup actions for areas
identified as high priority in the Harbor waters and per the Sediment Management Plan.
■ Phase III
The purpose of Phase III is to implement secondary and additional remediation actions as
necessary to be in compliance with final waste load and load allocations by the end of the
TMDL implementation period.
3. Los Angeles River and San Gabriel River
Responsible parties in these watersheds are implementing other TMDLs, which will directly or
indirectly support the goals of this TMDL.
■ Phase I
Responsible parties for each watershed shall submit a Report of Implementation to describe
how current activities support the downstream TMDL.
- Phases Hand III
Implementation actions may be developed and required in Phases II and III as necessary to
meet the targets in the Greater Harbor waters. TMDLs to allocate contaminant loads
between dischargers in the Los Angeles and San Gabriel Rivers watersheds may also be
developed, if necessary.
4. Special Studies and Reconsideration of TMDL Targets, Allocations, and Schedule
This TMDL recognizes that as work to understand these waters and the chemical, physical and
biological processes, continues, the targets, allocations, and the flow threshold for wet - weather
conditions and the implementation actions to reach those targets and allocations may need to be
adjusted. Furthermore, if impairments are identified during flow conditions less than the 90"'
percentile flow in Dominguez Channel and/or Torrance Lateral, additional allocations for those
flow conditions will be developed and applied at the TMDL reconsideration. In addition, it may
be necessary to make adjustments to the TMDL to be responsive to new State policies
including, but not limited to, SQO Part II; toxicity policy; possible changes to air quality criteria
and other regulations affecting air quality.
Optional special studies, which could result in changes to these TMDLs, include but are not
limited to: studies to further refine the site specific link between sediment pollutant
concentrations, depth of bed sediment contamination and fish tissue concentrations;
foraging ranges of targeted fish; additional data to refine watershed and hydrodynamic models,
including that collected pursuant to this TMDL; additional data on contaminant contributions of
the Los Angeles River or San Gabriel River to Greater Harbor waters; stressor identifications;
and additional diazinon data. Completion of studies to further refine the site specific link
between sediment pollutant concentrations and fish tissue pollutant concentrations and
evaluate the range and habitat of specific fish populations will be used to evaluate
changes in TMDL targets, WLAs and LAs, and to guide future implementation actions.
In addition, further characterization of direct air deposition loadings for heavy metals and
legacy pesticides is an optional special study. Allocations of certain pollutants in certain
-33- May 5, 2011
Attachment A to Resolution No. Rl1 -008
waterbodies are confounded by the existing estimates of pollutant loading via direct air
deposition onto the waterbodies. Additional monitoring of these pollutants at air sampling sites
more closely resembling the respective waterbodies will help characterize these loadings.
Limited data exist for dry deposition so this study could be extended over longer timeframes.
Measurements of wet deposition for each pollutant may also be appropriate to estimate air
deposition more completely. Study results could provide data to reconsider pollutant - specific
allocations in this TMDL.
Detection of DDT compounds in water or sediment samples collected within Torrance Lateral
shall trigger additional monitoring, by parties to be determined by the Executive Officer, in
coordination with EPA, to evaluate potential contribution from contaminated soils related to
upstream Montrose operable units discharging via the Kenwood storm drain. Upon
reconsideration of the TMDL, all monitoring results for DDT compounds collected by
responsible parties or other entities shall be considered as part of source analysis and to
determine potential future allocation(s) that may be necessary to minimize impacts to
downstream waters and restore beneficial uses in TMDL waterbodies.
As allocation- specific data are collected, interim targets for the end of Phase II may be
identified.
The TMDL will be reconsidered by the Regional Board at the end of Phase I to consider
completed special studies or policy changes.
S. Compliance with Allocations and Attainment of Numeric Targets
Compliance with the TMDL shall be determined through water, sediment, and fish tissue
monitoring and comparison with the TMDL waste load and load allocations and numeric
targets. Compliance with the sediment TMDL for metals and PAH compounds shall be based
on achieving the loads and waste load allocations or, alternatively, demonstrating attainment of
the SQO Part 1 through the sediment triad/multiple lines of evidence approach outlined therein.
Compliance with the TMDLs for bioaccumulative compounds shall be based on achieving the
assigned loads and waste load allocations or, alternatively, by meeting fish tissue targets. If at
any point during the implementation plan, monitoring data or special studies indicate that load
and waste load allocations will be attained, but fish tissue targets may not be achieved, the
Regional Board shall reconsider the TMDL to modify the waste load and load allocations to
ensure that the fish tissue targets are attained.
The compliance point for the stormwater WLAs shall be at the storm drain outfall of the
permittee's drainage area. Alternatively, if stormwater dischargers select a coordinated
compliance monitoring option, the compliance point for the stormwater WLA may be at storm
drain outfalls or at a point in the receiving water, which suitably represents the combined
discharge of cooperating parties discharging to Dominguez Channel and Greater Los Angeles
and Long Beach Harbor waters. Depending on potential BMPs implemented, alternative
stormwater compliance points may be proposed by responsible parties subject to approval by
the Regional Board Executive Officer. The compliance point(s) for responsible parties
receiving load allocations shall be in the receiving waters or the bed sediments of the
Dominguez Channel and the Greater Los Angeles and Long Beach waters.
