To:                   Angela Nugent, Special Assistant/Designated Federal Officer EPA Science Advisory Board Staff Office

From:               Winona Victery and Eugenia McNaughton Management and Technical Services, Region 9

Region 9 of the U.S. Environmental Protection Agency (EPA) is charged with protecting human health and the environment over a large and diverse area (Arizona, California, Hawaii, Nevada, American Samoa, Guam, and the Commonwealth of Northern Mariana Islands). The Region also works with environmental agencies in Asia, Mexico, and the Pacific Islands.

Our regulatory oversight in air, water, land, and waste extends to communities, ecosystems, environmental stewardship, rural areas, tribal lands, large cities, agriculture, fisheries, forests, mining, industry, shipping, and refineries. These are found in diverse environmental settings including deserts, forests, mountains, valleys, tropical islands, rain forests, bays, and coastlines.

Region 9 is fortunate to have a number of talented and motivated scientists on staff with expertise in a variety of disciplines. These scientists are supported by a Regional Science Council, with representatives from each Division, and a Regional Science Team composed of the Deputy Director of the Management and Technical Services Division, the Regional Laboratory Director, the Quality Assurance Office Manager, the Superfund and Technology Liaison (STL), the Regional Science Liaison (RSL), and two Science Policy Advisors.

Our goals for applying science to the regulatory decision-making process in Region 9 include:

  • promoting the use of science to improve the regulatory process and achieve EPA’s mission;
  • “doing the right science” by identifying and addressing science priorities;
  • “doing science right” by encouraging sound scientific practices; promoting scientific innovation;
  • using data of appropriate quality in support of regional priorities and effective decision-making;
  • partnering with our states, tribes, local governments, non-governmental organizations and academic institutions to promote common environmental goals; and
  • collaborating with EPA ORD scientists on projects of regional and national interest.

Included with this memorandum are short biographies of the Senior Management Team, the managers, staff and science team with whom you will be meeting. There is a description of EPA Southwest Region, Region 9 and organization chart, several fact sheets describing science related activities and links to several products that were the result of scientific work initiated and completed by the Region in collaboration with our various partners.

Dust Suppressants and Water Quality


Regional Applied Research Effort Testing of Dust Suppressants for Water Quality Impacts

The use of dust suppressants not only enhances dust control but can also significantly reduce the amount of water needed to effectively control dust. However, application of dust suppres- sants could also negatively impact the quality of underground water and surface water bodies through infiltration or storm water runoff.

The purpose of this research was to identify dust suppressant products with minimal to no adverse impacts on water quality and aquatic life relative to use of water alone. Simulated stormwater runoff from small-scale soil plots treated with six dust suppressant products was evaluated for water quality and aquatic toxicity. The study also evaluated the quality of water leached through soils treated with dust suppressant products. The study design replicated, to the extent possible, conditions under which dust suppressants are typically applied at construction sites in desert climates.

  • Enviro RoadMoisture 2.5 (surfactant)
  • Durasoil (synthetic organic)
  • Jet-Dry (surfactant)
  • Haul Road Dust Control (surfactant)
  • EnviroKleen (synthetic polymer)

Overall, water quality results for the dust suppressant products were favorable and generally minimal, showing concentrations similar to wa- ter-only control tests on untreated soils for the majority of parameters evaluated. However, this study is not a substitute for site-specific monitoring of dust suppressant impacts and results should not be applied to products that were not tested.

What is EPA’s School Air Toxics Monitoring Initiative?

As part of a new air toxics monitoring initiative, EPA, state and local air pollution control agencies will monitor the outdoor air around schools for pollutants known as toxic air pollutants, or air toxics. The Clean Air Act includes a list of 187 of these pollutants. Air toxics are of potential concern because exposure to high levels of these pollutants over many decades could result in long- term health effects.

EPA selected schools after evaluating a number of factors including results from an EPA computer modeling analysis, the mix of pollution sources near the schools, results from an analysis conducted for a recent newspaper series on air toxics at schools, and information from state and local air pollution agencies.

EPA, and our state, local and tribal air pollution control partners are:

  • collect samples of outdoor air near selected schools over 60 days,
  • analyze those samples for air toxics of potential concern,
  • report on levels of air toxics found and their potential for long-term health impacts,
  • evaluate actions that may be needed to reduce levels of pollutants of concern, and
  • take action as needed to ensure that nearby industries are in compliance with clean air regulations.

This web site provides information on this initiative in EPA’s Pacific Southwest Region (Region 9). For additional information, please visit the national Web site.

How Many Schools Will Be Monitored Under This Initiative?

The initial monitoring will take place at 62 schools in 22 states. If your school is not on the initial list of schools to be monitored, it does not mean it might not be monitored in the future. We will use what we learn from the initial round of monitoring to help us determine whether we may need to conduct additional monitoring.

How Did EPA Decide Which Schools To Monitor?

EPA identified schools for monitoring based on the best data available to us about air pollution in the vicinity of the school, information about wind direction and speed, results of a computer modeling analysis, results from a recent newspaper analysis, and information from state and local air agencies.

Which Schools Will EPA Be Monitoring in Region 9?

Picture Placeholder

EPA Region 9, in partnership with the Bay Area Air Quality Management District and the South Coast Air Quality Management District, will initially be monitoring at the following school locations. Please click on the school name for information regarding the monitoring efforts at each school, and on the name of the pollutant(s) for additional information.

School Name



Pollutant(s) to be monitored*

Felton Elementary School



Metals in TSP, PAH, VOC

Santa Anita Christian Academy

El Monte


Metals in TSP, PAH, VOCs

Soto Street Elementary School

Los Angeles


Metals in TSP, PAH, VOCs

Stevens Creek Elementary School




* Pollutants to be measured have been selected based on emission sources in the vicinity of each school.

Cr+6: Hexavalent chromium

Metals in TSP: Toxic metals contained in total suspended particulate matter (e.g., lead, nickel and manganese).

PAH: Polycyclic Aromatic Hydrocarbons (e.g., naphthalene, benzo(a)pyrene).

VOC: Volatile Organic Compounds (e.g., benzene, vinyl chloride).

Note: The groups of chemicals identified for each school as “pollutants to be monitored” include both the specific individual pollutants within the group that our current information indicates may be present at each school at levels of potential concern (i.e., the “driver pollutants”) and some other pollutants that can be inexpensively measured at the same time. While we will be analyzing air samples for both sets of pollutants in each chemical group and will review all the data in drawing conclusions for each school, we intend to focus our data analysis activities primarily on the individual “driver pollutants”.

For information on all schools being monitored nationwide, please refer to the Assessing Outdoor Air Near Schools Web site.

Why Isn’t My School On the List of Schools for Monitoring?

EPA is going to start by monitoring at 62 priority schools in 22 states near large industrial facilitates and in some urban areas. If your school is not on the initial list of schools to be monitored, it does not mean it might not be monitored in the future. We will use what we learn from the initial round of monitoring to help us determine whether we may need to conduct additional monitoring

EPA Region 9 received a significant number of inquiries about monitoring schools in West Berkeley and Bayview/Hunters Point in San Francisco. EPA has prepared responses to these inquiries, which can be viewed below:

Letter to West Berkeley Residents (PDF) (2 pp, 24K)

Letter to Bayview-Hunters Point Residents (PDF) (2 pp, 23K)

What Can Schools Do to Improve Air Quality?

The air children breathe impacts their health. People exposed to toxic air pollutants at sufficient concentrations and durations may have an increased chance of health problems including damage to the immune system, and neurological, developmental, respiratory and other health problems including cancer. In some cases, children may be more vulnerable to these health effects than adults because:

  1. their bodies are still developing; and
  2. their behavior can expose them to more chemicals.

Learn more about children’s health issues

In addition to assessing outdoor air near schools, EPA has several existing programs that take action to help make the air in and around schools safer for children to breathe:

Indoor levels of air pollutants can be two to five times higher than outdoor levels. Sources of poor indoor air quality in schools range from inadequate ventilation systems to fumes from pesticides and cleaning agents. More than half of the nation’s schools are implementing indoor air quality management programs, most of which are based on EPA’s Tools for Schools Program, which helps schools identify, resolve and prevent indoor air quality problems using low- and no-cost measures.

EPA launched the Clean School Bus USA Program in 2003 to address the condition of America’s aging school bus fleet and the health effects that result from exposure to diesel exhaust emitted by idling school buses. EPA has provided grants to many school districts to fund the replacement of old school buses with new buses that use cleaner fuels.

EPA’s Healthy School Environments web site is a “one-stop shop” for resources and information on topics related to environmental health and safety in schools.

EPA is also taking action to be sure that levels of lead, ozone, and fine particle pollution in the air protect children’s health. Learn more about each:

  1. Lead
  2. Ozone
  3. Particle pollution

Using Technology to Assess Air Quality in the San Joaquin Valley

Technical information on this page:

  • Graphic of NASA’s satellite support of air sampling
  • Graphic depiction of aerial data gathered.

It may sound like fiction – NASA pilots, EPA scientists, lidar instruments, and an airplane flying back and forth over the San Joaquin Valley – but it is a fact.

Last week, in an effort to better understand how particulate matter pollution is formed, EPA teamed up with NASA scientists to bring advanced monitoring technology to the valley.

Air pollution is easily trapped inside a valley and the San Joaquin Valley is long, low, and surrounded by mountains on three sides. The recent population boom, busy highways, and other sources of pollution have combined with the natural topography to create some of the highest concentrations of fine particulate pollution in the country. Improving the valley’s air for the 3.3 million people who live there is a priority for EPA.

The plane that flew over the valley was equipped with lidar, an advanced monitoring instrument from NASA that makes unique aerosol (particulate matter) measurements. These measurements give a downward snapshot of the entire aerosol that is in the atmosphere. (See the graphic below.) The measurements are useful for assessing the sources and transport of the aerosol.

The data gathered during the flights can help us better understand the underlying science of particulate matter pollution and help the San Joaquin Valley Air Pollution Control District develop more informed air quality plans. EPA will continue to work with the California Air Resources Board and the SJV APCD, as we strive toward the same goal – cleaner air for the valley residents.

Analysis of dioxin-like compound in fish tissue from San Francisco Bay

In the summer of 2000, the USEPA Region 9 coordinated with the San Francisco Estuary Institute (SFEI) to fund the analysis of dioxins and dioxin-like compounds (furans and co-planar PCBs) in fish collected as part of the Regional Monitoring Program. Samples were collected from six areas from within the Bay: the South Bay, Oakland, San Leandro Bay, San Francisco Waterfront, Berkeley, and San Pablo Bay.

Thirty-two fish composites were analyzed for dioxins, furans and co-planar PCBs (PCB-77, PCB- 126, PCB-169) with High Resolution Mass Spectrometry by the Department of Toxics Substances Control Lab in Berkeley CA. The other dioxin-like PCBs (105, 114, 118, 156, 157 and 189) were measured by a California Department of Fish and Game Laboratory in Rancho Cordova, CA.

The potency of PCBs, dioxins and furans has been assessed by the World Health Organization (1998) and the combined potency of a sample is expressed as a Toxic Equivalency Quotient (TEQ in pg/g). The dioxin toxic equivalents resulting from dioxins and furans alone are expressed as ITEQs. The TEQ and ITEQ were compared to screening level concentration of 0.3 pg/g. A screening value is a concentration of a target analyte in fish tissue that is of potential public health concern. Exceedance of screening value is an indication that more intensive site-specific monitoring and/or evaluation of human health risk should be conducted.

Approximately 80% of total TEQ in fish tissues is due to PCBs. PCB-126, the most potent dioxin-like congener, contributed an average of 49% to the total TEQ. The dioxins and furans contributed about 20% of the TEQ. These were primarily associated with four compounds: 2,3,4,7,8-PCDF, 2,3,7,8-TCDF, 2,3,7,8-TCDD, 1,2,3,7,8-PCDD. Based on the TEQ data three fish species had median concentrations above the screening level of 0.3 pg/g. The ITEQ is more equivocal. All white croaker (n = 14) and shiner surfperch (n = 8) samples were above the screening level of 0.3 pg/g. On the other hand, all striped bass (n =9 ) and the jacksmelt (n = 1) were below the screening level of 0.3 pg/g.

The results are similar to those found in the previous RMP survey conducted in 1997. Most of the TEQ is due to the co-planar PCBs. However, dioxins alone are higher than screening levels in some fish. This study provided data on two Bay species (shiner surfperch and jacksmelt) that had not been previously analyzed for dioxins.

Performance Report

Environmental Management System

The City of Los Angeles processes, recycles and renews 159 billion gallons of wastewater produced annually by more than four million residents. Twenty one billion gallons of this wastewater is used as recycled water for beneficial water-conservation purposes. Two hundred and fifty six thousand tons of biosolids are fully recycled and are treated as a valuable commodity. The City managed 92% of its biosolids as fertilizer, and 8% as compost.

Terminal Island Renewable Energy (T.I.R.E.) Project Start Up

In April 2007, the City of Los Angeles and Terralog Technologies Inc. began construction for the Terminal Island Renewable Energy (TIRE) project. Two wells were drilled and injection equipment was initially installed. The start-up phase commenced in June 2008, and the equipment was tested with brine   and effluent from the Terminal Island Water Reclamation Plant. In August 2008, the City injected the first biosolids from Hyperion Treatment Plant and Terminal Island Water Reclamation Plant. The biosolids were injected successfully and the well accepted the material. In October 2008, the TIRE project reached its first permit milestone: the successful demonstration of biosolids injectivity and the review of well formation response. This mile- stone was accomplished 35 days ahead of schedule. Currently, approximately 150 wet tons of biosolids are injected 5 days a week.

Daily monitoring and measurement are conducted on the project. A Technical Advisory Committee (TAC) monitors the project operations and analyzes the well response data. The committee includes the U.S.

Environmental Protection Agency; Office of Groundwater Protection; Underground Injection Control  and  Biosolids Management; Department of Energy; California Institute of Technology (CalTech);  US  Geological  Survey; Lawrence Berkeley National Lab and California Division of Oil; and Gas  and  Geothermal.  Based  on review of the data and monitoring by the TAC,  the results show that the well has responded soundly to the   injection and the material is contained vertically.

Extensive outreach efforts were provided for the TIRE project. To date, over 60 presentations, including tours, have been given. As a result of the City’s efforts, the TIRE outreach program was recognized by the National Association of Clean Water Agencies for its environmental leadership in providing an effective public outreach and education program for TIRE.

The City has seen several environmental benefits during the start-up phase of the TIRE project:

  1. Reduction in air emissions and green-house gases due to a decrease in truck traffic.
  2. Reduction in the number of trucks transporting the material to management options outside of the Los Angeles basin from 14 per week to an average of 4 per week.
  3. Met permit and regulatory requirements thus far, resulting in protection of groundwater, improved air quality, and odor free operations.

Our Accomplishments

The City continually improves its program each year by accomplishing goals and objectives set. The table below lists some accomplishments the City achieved in FY 07-08.

Turning Food Waste into Energy at the East Bay Municipal Utility District (EBMUD)


EBMUD Helps Mitigate Climate Change Through Anaerobic Digestion

Fact: Food Waste Contributes to Climate Change


Food waste is one of the least recovered materials in the municipal solid waste stream and is one of the most important materials to divert from landfills. Food that is disposed of in landfills decomposes to create methane, a potent greenhouse gas that contributes to climate change.


More about the importance of diverting food waste from landfills


Fact: Food Waste Can Be Transformed Into A Natural Fertilizer


Of the less than 3% of food waste recovered from the waste stream, composting is the prominent diversion method. Composting, either in your backyard or in a commercial facility, creates a natural fertilizer with many beneficial qualities.


More information on composting


Fact: Food Waste Can Be Used to Generate Renewable Energy


In order to decrease food waste and mitigate climate change, East Bay Municipal Utility District (EBMUD) is pioneering an innovative method of reducing the amount of food waste reaching landfills while simultaneously producing renewable energy.

Picture Placeholder

This food waste can be anaerobically digested for energy value and landfill diversion.

In Oakland, California, EBMUD’s main wastewater treatment plant was the first sewage treatment facility in the nation to convert post-consumer food scraps to energy via anaerobic digestion. Waste haulers collect post-consumer food waste from local restaurants and markets and take it to EBMUD. In an anaerobic digester, bacteria break down the food waste and release methane as a byproduct. EBMUD then captures the methane and uses it as a renewable source of energy to power the treatment plant. After the digestion process, the leftover material can be composted and used as a natural fertilizer.

Regional Applied Research Effort

Smart Energy Resources Guide:

A Resource for Greener Remediation

Remedial actions taken to clean up hazardous waste sites for environ- mental restoration and potential reuse are often themselves sources of diesel and green- house gas (GHG) emissions. The Cleanup-Clean Air Initiative (CCA) was established by U.S. EPA Region 9’s Superfund and Air Divisions to encourage GHG and diesel emissions reductions at cleanup sites. Through these efforts, CCA staff engaged in pilot projects and changed Emergency and Rapid Response Service and Response Action Contracts to include language on renewable energy and clean diesel.

Many remediation systems, such as pump-and- treat, may operate for many years, demanding electricity from fossil fuel-powered utilities. Heavy-duty equipment used in construction during site remediation is usually diesel powered. Opportunities to reduce these emissions exist through innovative approaches and new technologies. The purpose of the Smart Energy Resources Guide (SERG) is to provide information on available mechanisms to reduce emissions from energy use at cleanup sites. Examples include energy efficiency upgrades, implementing on-site renewable energy projects, and carbon sequestration.

An overview of renewable energy technologies is presented including costs, availability, applicability, estimated emissions reduction bene- fits, considerations, permitting, vendor information, funding resources, and success stories. Renewable energy technologies covered in this guide are solar, wind, landfill gas, anaerobic digesters, and gasifiers. Additional methods for using renewable energy are provided. Similar information is provided for diesel emissions re- duction technologies and cleaner fuels. This document includes information on reducing diesel emissions through retrofitting diesel equipment, using cleaner and alternative fuels, and simple, low-cost practices such as idle reduction. Currently, approximately 15 EPA cleanup sites are using cleaner diesel technologies and fuels or renewable energy to power their remediation systems.

The SERG is a tool for project managers to help them assess and implement these technologies and practices at cleanup sites. With this information, project managers may be better prepared to discuss emissions reductions strategies with contractors and developers. While resources cited in this document focus on U.S. EPA Region 9, many are applicable in other parts of the United States.

Clear Creek Management Area

Risk Assessment


Seven typical CCMA use scenarios were created from the individual activities for which EPA collected air samples. Risk estimate calculations were then conducted for the scenarios. The scenarios were designed to make the risk estimations better reflect typical CCMA use patterns and provide more useable information to Bureau of Land Management (BLM) and the public. The scenarios were developed with input from BLM and the California Department of Toxic Substances Control. Five of the seven scenarios represent recreational/volunteer use of CCMA, and two represent typical worker use. The five recreational scenarios are:

Scenario 1 Weekend Rider: Drive in, motorcycle on Saturday, camp on Saturday, sleep in tent, camp on Sunday, motorcycle on Sunday, drive out, vehicle wash, vehicle vacuum.

Scenario 2 Day Use Rider: Drive in, stage (prepare for riding), ATV or motorcycle riding, stage, drive out, vehicle wash, vehicle vacuum.

Scenario 3 Day Use Hiker: Drive in, stage, hike, stage, drive out.

Scenario 4 Weekend Hunter: Drive in, hike/hunt on Saturday, camp on Saturday, sleep in tent, camp on Sunday, hike/hunt on Sunday, drive out, vehicle wash, vehicle vacuum.

Scenario 5 Combined Rider/Workday: Drive in, stage, ATV or motorcycle riding, fence building/repair, stage, drive out, vehicle wash, vehicle vacuum.

The typical worker scenarios are:

Scenario 6 Patrol: Stage at Section 8, drive in and stage at CCMA (lead SUV only, ATV or motorcycle patrolling (lead rider only), stage and drive out(lead SUV only), vehicle wash, vehicle vacuum, unpacking at Section 8.

Scenario 7 SUV/Truck Patrol: SUV/truck patrol (lead SUV only), vehicle wash, vehicle vacuum.

Risk Assessment Methods – Excess Lifetime Cancer Risk estimates were calculated for the scenarios using both the

U.S. EPA Integrated Risk Information System (IRIS) and the California EPA Office of Environmental Health Hazard Assessment (OEHHA) toxicity values for asbestos. These are standard methods for estimating risk.

Adult, Child, and Child/Adult Risk Estimates – Consistent with the EPA Risk Assessment Guidance for Superfund (RAGS), a 30-year exposure duration was used for estimating excess cancer risks from the CCMA adult recreational and worker exposures. The risk assessment estimates risks for an adult who visits CCMA for 30 years, a child who visits for 12 years (ages 6 to 18) with his/her parents and then continues to visit for an additional 18 years as an adult (30 years total exposure), and a child who visits for 12 years from ages 6 to 18.

CCMA Use Frequency – The EPA RAGS guidance requires that risks be estimated for the reasonable maximum exposure (RME) that is expected to occur at a site under both current and future land-use conditions. Based on surveys and interviews, an earlier risk assessment conducted by BLM estimated a CCMA recreational RME of 5 off- road vehicle rides a year. Because some users indicated that they rode more frequently, the BLM assessment also used a “high” estimate of 12 days per year. Risks were also calculated for one-day per year to provide a range of estimates and exposures. The EPA risk assessment incorporates the 1, 5, and 12 visit per year frequency of the earlier BLM assessment for Scenarios 1 through 5 and, at BLM’s request, uses a 1, 60, and 120 day per year frequency for the worker scenarios, Scenarios 6 and 7.

Risk Assessment Results – Excess Lifetime Cancer Risk estimates for Adult, Adult/Child, and Child exposures using the U.S. EPA IRIS risk model are shown in Figures 6 through 8. The Excess Lifetime Cancer Risk estimates using the Cal/EPA OEHHA model are shown in Figures 9 through 11. For reasons that are explained in more detail in the risk assessment report, the OEHHA toxicity value for asbestos is eight times higher than the IRIS value, and the OEHHA risk calculations reflect the greater toxicity. The IRIS and OEHHA risk estimates can be thought of as bracketing the range of possible risks from CCMA asbestos exposure.

The EPA Superfund program defines the acceptable risk range for exposure to a carcinogen, like asbestos, as 10-4 (1 in 10,000) to 10-6 (1 in 1,000,000) excess lifetime cancer risk. Exposures which are calculated to cause more than 1 in 10,000 excess cancers are considered to be of concern and may require action to reduce the exposure and resulting risk. It is important to note that the risk assessment present quantitative estimates of excess cancer risk over a lifetime in a population based on the defined exposure scenarios. The scenarios have been designed to represent current and future exposures for recreational and working users of CCMA. The numbers do not predict individual exposures or individual health outcomes.

Clear Creek Management Area


The Clear Creek Management Area (CCMA) in San Benito and Fresno Counties is located on one of the largest naturally occurring asbestos deposits in the world. The rugged terrain overlaying this 31,000-acre serpentine deposit is a popular and challenging riding spot for off-road motorcyclists. The naturally barren slopes, bald ridges, chaparral and rare plants are also enjoyed by rock collectors, botanists, hikers, hunters and campers, including families with children. Thousands of visitors each year use hundreds of miles of criss-crossing routes, a legacy of historic mining activities in the area.

The CCMA is managed by the Department of the Interior’s Bureau of Land Management (BLM).  Within the boundaries of the CCMA is the Atlas Asbestos Mine Superfund site. In 1991, EPA signed the Record of Decision (ROD) selecting the cleanup remedy for the Atlas Mine. In the ROD, EPA designated the CCMA as one of four geographic areas that comprise the site, but did not propose a cleanup action for the CCMA.  Instead, EPA stated that it would evaluate whether the BLM’s plans for management of CCMA were adequate to protect public health from exposure to asbestos found in the CCMA’s soil and air. BLM has designated the area as hazardous, and asbestos warning signs are posted at entry points and on bulletin boards.

In 2004, as part of the evaluation of the Atlas Mine cleanup for possible delisting of the site from the federal Superfund list, EPA initiated an asbestos exposure and human health risk assessment for the CCMA. The goals of the assessment were:

  • To update the 1992 BLM Human Health Risk Assessment by using current asbestos sampling and analytical techniques, and
  • To evaluate risks to children because families are frequent visitors to CCMA.

BLM will use the information provided in the assessment to evaluate management and use alternatives in an upcoming environmental impact statement for managing the CCMA. The final Clear Creek Management Area Asbestos Exposure and Human Health Risk Assessment report was released by EPA on May 1, 2008 and is summarized on this website, please use the tabs at the top to navigate among the pages.

Clean Land

Hazardous Waste in EPA’s Pacific Southwest Region

EPA carries out several federal laws dealing with hazardous waste: First is Superfund, which cleans up the nation’s biggest, costliest abandoned hazardous waste sites (the National Priorities List), as well as sites where quick action is needed to deal with imminent threats to public health or the environment. Second is the Resource Conservation and Recovery Act, which regulates hazardous waste storage, transportation, and disposal; cleans up spills and leaks at hazardous waste and underground fuel storage facilities; and encourages saving energy and natural resources through waste recycling, recovery, and reduction. Third is Brownfields, which promotes cleanup and reuse of sites with less serious contamination. Cleanups under these laws are based on the “polluter pays” principle, which means that in most cases, taxpayers don’t get stuck with the bill.

In 2003, EPA’s Pacific Southwest Region secured binding commitments totaling over $128 million from responsible parties to pay for hazardous waste cleanups. Construction of cleanup facilities (such as groundwater treatment plants) is complete at 44% of the region’s 123 Superfund National Priorities List sites, and construction is underway at another 36% of the sites. The remaining 20% are in the investigation stage, although early action has been taken to deal with immediate risks.

collaborating on Revitalization


Last year, EPA accelerated efforts to revitalize abandoned industrial sites (brownfields) with grants totaling over $7 million in the Pacific Southwest Region to state and local governments, tribes, and nonprofits for assessment, cleanup, a revolving loan fund for cleanups, and job training. This included, for the first time, sites contaminated with leaking fuel from underground storage tanks.

Homes, Jobs and a Ballpark

EPA awarded the city of Oakland, Calif., a $100,000 grant to help assess and clean up abandoned gas station sites where potential soil contamination from leaking underground tanks has hindered redevelopment. At one site, EPA worked with Oakland and Alameda County to clear the way for four homes to be built by Habitat for Humanity on a former gas station site in the city’s Fruit vale neighborhood. Families moved into the new homes in October 2003. Nearby, EPA grant funds are being used to clean up a former industrial area adjacent to the Bay Area Rapid Transit (BART) rail system so that the site can be redeveloped into a “transit village” with homes, shops, and offices clustered around BART’s Fruitvale Station.

In Los Angeles, EPA awarded a $200,000 grant to the city for environmental job training at Brownfields sites. The city’s Community Development Department has targeted the Wilmington industrial tract near the Port of Los Angeles, the

Goodyear tract in South Central and the Crown Coach site near East Los Angeles for assessment, cleanup and redevelopment. The city plans to train 50 students, achieve an 80 percent placement rate, and track students for a full year. The seven-week, 300-hour job training program consists of hazardous waste handling, innovative environmental technologies, lead abatement, and asbestos abatement. Recruitment will focus on low- income residents and placement will be conducted by the city’s WorkSource Centers.

In West Covina, Calif., EPA and California’s Department of Toxic Substances Control entered into two prospective purchaser agreements with the city to clear the way for a planned Big League Dreams sports complex and a municipal golf course on parts of the former BKK Landfill site. Other parts of the property were used as a hazardous waste landfill, and a municipal waste landfill as recently as 1996. The agreements encourage reuse of the land the city plans to purchase from the BKK Corp. The city may sell the land for commercial development, or develop it without incurring liability for cleanup costs. However, the agreements do not relieve BKK, the owner and operator of the landfills, from liability.

At the WDI Superfund Site in Santa Fe Springs, Calif., that city is using a grant from EPA’s Superfund Redevelopment Initiative to develop a specific plan for beneficial reuse of the site. Parts of the 38-acre site, including a buried concrete reservoir, were formerly used for disposal of oil drilling wastes. Construction of an impermeable cap over the waste reservoir and installation of monitoring systems is expected to be underway by mid-2004.

Cleanup Highlights

Iron Mountain Mine

At the Iron Mountain Mine near Redding, Calif., one of the nation’s toughest, costliest cleanup challenges, EPA completed construction of the $40 million Slickrock Creek Retention Reservoir, which collects polluted runoff from the former mine. The runoff is extremely acidic and tainted with toxic dissolved copper and zinc. This dam and reservoir, together with a treatment plant already in operation, now prevent 95% of the mine’s toxic discharges from flowing into the Sacramento River. The river has four salmon spawning runs each year, and supplies drinking water directly to 70,000 people.

The treatment plant, built in the early 1990s, has treated over 1.05 billion gallons of poisoned water, the equivalent of 120,000 tanker trucks, and prevented 1.6 million pounds of copper and 5.6 million pounds of zinc – 80-90% of the mine’s toxic discharges – from reaching the river. Before treatment began, the mine discharged more than a ton of toxic metals into the river per day, making it the nation’s largest discharger of toxic metals.

The mine, active for more than a century but abandoned in the 1960s, honeycombed the mountain with tunnels. The tunnels now act as conduits for air and water, which percolates through the metal-bearing ores of the mountain, sustaining six strains of sulfur- and iron- loving bacteria, which dissolve the metals and acidify the water. The chemical reactions involving the bacteria and water are continuous, creating a constant flow of toxic runoff to creeks that border the mountain. The rainy season increases the flow. Cleanup efforts have focused on capturing the runoff and treating it to neutralize the acidity and remove the metals. The resulting cleaner water can then flow downstream harmlessly, but tons of inert sludge from the treatment process must be trucked back up the mountain for disposal in pits left by earlier mining operations.

In December 2000, EPA successfully settled cost recovery litigation, providing $160 million to assure that the treatment plant will be operated and maintained in perpetuity. It was the largest settlement with a single potentially responsible party in EPA history.

EPA Regional Administrator Wayne Nastri presents a “big check”for a $100,000 grant to Los Angeles Councilwoman Janice Hahn and Deputy Mayor Jonathan Kevles. The grant will help the city assess, clean up, and redevelop abandoned gas station sites like this one, where leaking underground storage tanks may have contaminated soil and groundwater.

Santa Monica Drinking Water Cleanup

In November 2003, EPA and the Los Angeles Regional Water Quality Control Board facilitated an agreement between the city of Santa Monica and three major oil companies to restore the Charnock Sub-basin as a drinking water source. This well field, which formerly supplied about half the city’s water, had been shut down since 1996, when its water was found to be contaminated with MTBE, a gasoline additive that had leaked from underground fuel tanks at 27 sites.

In 1999, EPA and the Regional Board ordered the oil companies to supply replacement water to the city, at a cost of more than $3 million a year – a total of more than $13 million by late 2003. The 2003 legal settlement requires the oil companies to build treatment systems for the Charnock water supply wells, to remove the MTBE as water is pumped out. “This agreement proves that when all levels of government – local, state and federal – work together, we serve the common good and produce a comprehensive solution to a difficult problem,” commented EPA Regional Administrator Wayne Nastri.


Perchlorate is a rocket fuel component that became detectable in water at low levels in 1997, when the state of California developed a new testing method for it. Although the level at which perchlorate poses a risk is under review by the National Academy of Sciences, this chemical can disrupt the thyroid gland, which is essential for proper development of newborns and infants.

Since 1997, perchlorate has been found in groundwater in 348 of 6,400 drinking water wells tested in California, and at 12 Superfund hazardous waste cleanup sites in California and Arizona. The presence of perchlorate has increased the cost of these cleanups, and delayed them, as cleanups already underway have had to be re-evaluated. Several such sites are in the San Gabriel Valley in Southern California, where a 10-square-mile plume of groundwater was found to be contaminated with perchlorate, in addition to other chemicals from industrial facilities. Treatment of the contaminated water to remove perchlorate began in 2000, and is expected to continue for at least 30 years.

The highest levels in EPA’s Pacific Southwest Region were found in Las Vegas Wash in Henderson, Nev., where a Kerr-McGee facility had manufactured the substance. Over the past two years, Kerr-McGee has been pumping the groundwater through a treatment plant, removing about one ton of perchlorate per day and reducing perchlorate levels in the wash by 70%.

In 2003, EPA ordered Goodrich Corp. and Emhart Industries, as potentially responsible parties, to investigate a 160-acre parcel in the Rialto-Colton area of San Bernardino County, which is a suspected source of perchlorate found in 10 nearby drinking water wells owned by several water supply systems.

A number of EPA’s nationally recognized perchlorate experts work out of the Pacific Southwest Regional Office and have played leadership roles in sorting out the technical, legal and regulatory issues surrounding perchlorate. For more information, go to www.clu- in.org/perchlorate.

One Cleanup Program: TCE in Mountain View, Calif.

In the Silicon Valley city of Mountain View, EPA and California state agencies are working together under EPA’s “One Cleanup” program at eight sites where groundwater has been contaminated with trichloroethylene (TCE). EPA is coordinating with the Regional Water Quality Control Board and the Bay Area Air Quality Management District on air monitoring, groundwater cleanup, and public outreach efforts so that investigation and cleanup issues are being addressed consistently across the sites.

In 2001, EPA’s new draft health risk assessment for TCE found that the chemical, which contaminates groundwater at hundreds of Superfund sites throughout the nation, may present a health risk at much lower levels than previously known. The new data caused concern in Mountain View, where TCE-tainted groundwater was being pumped out and treated by air-stripping at the Middlefield-Ellis-Whisman (MEW) Study Area, the Naval Air Station Moffett Field, and GTE sites. Nearby residents and workers worried that they might be exposed to harmful levels of TCE, either from soil vapor rising from the contaminated ground water through foundation cracks or plumbing conduits into buildings (vapor intrusion) or from the air-stripping devices, which can disperse low levels of TCE into the outdoor air.

In response to these community concerns, the potentially responsible parties (PRPs), who have been cleaning up the groundwater contamination at these sites for years, voluntarily replaced nine of the air strippers with liquid phase carbon treatment systems or advanced oxidation systems, both of which release no TCE into the air.

Picture Placeholder

In Mountain View, Calif., responsible parties removed equipment that had treated TCE- contaminated groundwater by air-stripping, and replaced it with systems that release no TCE into the air.

EPA directed the PRPs to test the indoor and outdoor air at 26 buildings and 66 residences that overlie the highest levels of TCE in shallow groundwater. EPA also began testing outdoor air at ten reference sites for comparison, and NASA did air sampling at the former NAS Moffett Field. Over 2,000 air samples were collected in 2003. EPA is using the data to evaluate the potential long-term health risks to building occupants and residents from the vapor intrusion pathway. All the data indicate that there is no short-term or immediate  health risk to residents or workers in the area.

To reduce long-term risks, PRPs took interim measures to reduce levels of TCE in the air in 12 commercial buildings and one residence where elevated levels of TCE were detected. The measures included sealing cracks in floors and potential piping conduits, installing a subslab depressurization system, and optimizing building ventilation systems.

EPA has also helped concerned community members form the Northeast Mountain View Advisory Council, which meets with EPA monthly to discuss air testing results and the ongoing groundwater cleanup, ask questions, and voice concerns.

Construction Complete: Sharpe Defense Depot and Koppers

EPA designated the Sharpe Defense Depot’s cleanup as a “construction complete” in 2003 when all short-term cleanup actions were complete and the groundwater pump-and-treat system was operating successfully. The 724-acre base near Lathrop, Calif., was listed on EPA’s Superfund National Priorities List following confirmation that metals, pesticides, and solvents had contaminated soil and groundwater at the site. The Army successfully remediated contaminated soils using soil vapor extraction and excavation with off-site disposal. Three groundwater treatment systems were installed to clean up the groundwater. Sharpe Defense Depot remains a functioning military base.

EPA also reached the “construction complete” milestone at Koppers, an inactive wood treating site near Oroville, Calif. A covenant of restrictions is in place designating the 205- acre site for industrial use only and restricting use of groundwater at the site. Groundwater contamination is contained and declining as water is pumped out, treated, and pumped back into the ground. This will continue for about 20 more years, until the water is clean.

Emergency Response

Building Emergency Response Capacity, Readiness

Since the tragedy of 9/11/2001, EPA has been increasing its capacity to respond to emergencies, regardless of cause. When chemical spills, oil spills, chemical fires, or hazardous waste present an imminent threat to public health or the environment, EPA has the authority to respond whether the emergency stems from an accident, terrorism, or extreme weather events like floods. In the Pacific Southwest, EPA has enhanced its emergency response infrastructure, opening new Emergency Response Field Offices in Las Vegas, Nev., and Long Beach, Calif., to shorten response time for emergencies in Arizona, southern Nevada, and southern California; a new Pacific Southwest response center in San Francisco; and new emergency response equipment warehouses in San Francisco and the Los Angeles area.

Picture Placeholder

In Fiscal Year 2003, EPA responded to 24 incidents in the Pacific Southwest where hazardous chemicals posed an imminent threat to human health or the environment.

Last year, EPA’s Pacific Southwest

Emergency Response staff participated in industry-sponsored spill drills as well as multi- agency simulated responses to biological attacks and intentional releases of radioactive materials in San Francisco, Seattle, and Clark County (Las Vegas), Nev. EPA also participated in exercises to strengthen security at nuclear power plants in the region.

Throughout the Pacific Southwest Region, EPA has been working with federal, state, and local health and air quality agencies to create a system for early detection of biological terrorism incidents. EPA continues to support state and local partner agencies building their capacity to respond to emergencies, in one case providing funding for a new hazardous materials emergency response truck for Washoe County, Nev. (the Reno-Tahoe area).

To deal with emergencies along the U.S.-Mexico border, EPA has worked with Mexican authorities to put bi-national sister city response plans in place that facilitate cooperation between U.S. and Mexican jurisdictions that face each other across the border. The fifth such agreement, for Tijuana and the city and county governments of San Diego, Calif., was signed in October 2003. In 2004, work is underway on the sixth sister city agreement in the Pacific Southwest Region, for the city of Mexicali, Baja California, and Calexico, Calif.

For oil and chemical spill prevention and preparedness, EPA routinely inspects industrial facilities for compliance with Spill Control and Countermeasure (SPCC) regulations, Facility Response Plan requirements, and the Emergency Planning and Community Right-to-Know Act (EPCRA). Violations found at 11 facilities resulted in penalties of over $830,000, including one involving a diesel spill on the lower Colorado River from fuel tanks on a farm. In addition to the routine inspections, last year EPA conducted three surprise oil spill drills at major oil storage and transport facilities, and visited seven high-risk chemical facilities in populated areas in the Pacific Southwest, to test their readiness. In 2004, EPA plans to conduct 12 surprise oil spill simulation exercises at major oil facilities.

Taking Rapid Action

In addition, EPA responded to 24 incidents involving hazardous chemicals and 13 oil spills in Fiscal Year 2003, including:

  • A nearly five-acre, three-story-high pile of construction and demolition debris in Fresno, Calif., caught fire on January 11, 2003. Smoke from the fire stayed low due to the winter inversion layer, creating air quality issues that prompted the local air district to issue health advisories and the state to request EPA assistance. Work ing within a Unified Command structure with more than 20 agencies, EPA conducted air monitoring, water management, fire fighting and heavy equipment operations and provided health and safety support. The Fresno Fire Department, Fresno County Environmental Health and the state’s Integrated Waste Management Board were key players in a month-long effort to extinguish the blaze. Once the fire was out, EPA partnered with the state waste board to remove the remaining 105,000 tons of debris to a permitted landfill.
  • At Ford City, a community near the National Petroleum Reserve in California’s Kern County, EPA worked with the state Department of Toxic Substances Control to remove 3,300 tons of lead-contaminated soil around 14 homes. The soil was disposed at the Clean Harbors hazardous waste landfill in Buttonwillow, Calif.
  • At the request of the Gila River Indian Community, EPA removed thousands of gallons of hazardous waste from an abandoned site on tribal land near Sacaton, Ariz. Nearly 100 55-gallon drums of flammable, toxic chemicals, and 3,000 gallons of hydrochloric acid sludge, were removed from a defunct company that extracted precious metals from mine waste.
  • EPA’s Pacific Southwest Region sent five on-scene coordinators to help with recovery of material from the Space Shuttle Columbia disaster in Texas.
  • On the Pacific island territory of Guam and the Com monwealth of the Northern Mariana Islands, which includes Saipan, EPA recovered, removed, and safely disposed of abandoned lab chemicals and pesticides.

EPA People – Ned Black

Picture Placeholder

Ned Black is the leading ecological risk assessor for the Pacific Southwest Region’s Superfund Division. In this role, he is responsible for laying a firm scientific foundation for EPA’s decisions on Superfund hazardous waste cleanups. His work is essential to ensuring that Superfund cleanups adequately protect human health and the environment.

Often, data is lacking on how each toxic chemical at a contaminated site affects the variety of species and habitats present, making it a challenge to produce scientifically defensible ecological risk assessments. To meet this challenge, Dr. Black chairs a Biological Technical Assistance Group (BTAG), which has become the primary forum for discussion of current technical literature among key staff from state and federal agencies, including the U.S. Fish and Wildlife Service. This group has brought a consistent, scientific, and consensus-based approach to the agencies’ ecological risk assessments. As a result, potential confrontation with responsible parties about assessments that form the basis for costly cleanup work has largely been avoided.

Through his efforts on the BTAG, Dr. Black has been instrumental in progress at some of the more contentious hazardous waste cleanup sites in the Pacific Southwest, including California’s Leviathan Mine, Casmalia, Alameda Naval Air Station, Hunters Point Naval Shipyard, and McClellan Air Force Base sites, and Hawaii’s Pearl Harbor site. Dr. Black has prepared or reviewed ecological risk assessments for each of these sites, and many more.

Dr. Black has also developed a two-day training class in ecological risk assessment, which he has made available to state and local government officials, as well as EPA staff. By sharing his knowledge and experience through this training and by nurturing the BTAG, Dr. Black has leveraged his effectiveness, providing the tools for state and local governments to make cleanup decisions based on defensible ecological risk assessments.

His success is due in large measure to his extensive, and nationally recognized, expertise in biology, ecology, and the scientific principles of ecological risk assessment. Dr. Black has brought a keen professionalism, dedication to EPA’s mission of protecting human health and the environment, and scientific credibility to cleanup efforts in the Pacific Southwest.

Regional Methods Project Summary

Collection of Pyrethroids in Water and Sediment

Regional Methods Program

Collection of Pyrethroids in Water and Sediment Matrices:

Development and Validation of a Standard Operating Procedure Loss of pyrethroid insecticides onto surfaces during sample collection can confound the interpretation of analytical and toxicity test results. Sample collection devices, container materials, and water matrix composition have a significant influence on the association of pyrethroids to container walls, which can be as high as 50 percent.

Any sample collection method involving transfer through multiple containers or pieces of equipment increases the potential for pyrethroid loss. This loose “surface-association” with container walls can be reversed through agitation.

When sampling water matrices with pumps or autosamplers, no pyrethroids were lost as long as the water was moving continuously through the system. When collecting water samples in containers, pyrethroid sorption to glass was less than to plastic, and sorption to plastic was less than to Teflon (glass < plastic < Teflon). Additionally, pyrethroids were easier to re-suspend from the glass container walls.

Since the amount of surface-association is proportional to the ratio of volume-to-contact- area of the sample, taking larger-volume field samples (greater than 3 liters) reducedpyrethroid losses to less than 10 percent. The amount of surface-association cannot be predicted easily because of the dependence on water matrix composition; samples with higher dissolved organic carbon or suspended- sediment concentrations were observed to have lower percent loss. Sediment samples were not affected by glass-container sorption (the only containers tested). Standardized sample-collection protocols are critical to yield accurate pyrethroid concentrations for assessment of potential effects (see text box).

Minimizing pyrethroid association to the surfaces of sampling equipment:

  • Container composition affects the extent of aqueous pyrethroid loss; pyrethroids associate less to glass containers than to plastic (HDPE or LDPE), and Teflon has the greatest pyrethroid loss caused by association to the container surface.
  • Containers should be agitated vigorously for at least 1 minute immediately before transfer to another sample container.
  • Maximize the volume-to-contact-area ratio.
  • When using a filtration apparatus or autosampler, pump speeds should be at 500 mL/min when pumping aqueous pyrethroids.
  • Composition of the water matrix affects the extent of pyrethroid association. Higher amounts of DOC or suspended sediments lessen the amount of pyrethroids associated to the container surfaces.
  • Appreciable losses of pyrethroids were not found for sediment samples collected in glass containers.
  • When possible, water samples should be analyzed within 3 days of collection. Sediment samples can be frozen for up to 6 months (prior to extraction).

Regional Science Strategy and Resources

“Science must be the backbone for EPA programs…”

The first of three EPA values articulated by new EPA Administrator Lisa Jackson, All Hands letter, January 23, 2009.

Region 9 of the U.S. Environmental Protection Agency (EPA), is charged with protecting human health and the environment over a large and diverse area (Arizona, California, Hawaii, Nevada, American Samoa, Guam, and the Commonwealth of Northern Mariana Islands). We also have environmental relations with Asia, Mexico, and the Pacific Islands. Our regulatory programs cover air, water, land, waste, communities, ecosystems, environmental stewardship, rural areas, tribal lands, large cities, agriculture, fisheries, forests, industry, shipping, refineries, and everything in between. In addition, Region 9 has diverse environmental settings including deserts, forests, mountains, valleys, tropical islands, rain forests, bays, and coastlines. This fact sheet describes our strategy for using science to help address environmental issues in EPA Region 9. For more information contact Matt Small, Regional Science Liaison (415) 972-3366.

Regional Science Strategy

As Scientists in Region 9, we seek to achieve the following:

  • Promote the use of science to improve the regulatory process and achieve EPA’s mission.
  • “Do the right science” by identifying and addressing science priorities.
  • “Do science right” by encouraging sound scientific practices.
  • Promote science innovation in the Region.
  • Effectively use environmental data in support of regional priorities and effective decision-making.
  • Build better partnerships with our states and academic institutions around common priorities and interests.

To accomplish these goals, we collaborate with the Office of Research and Development (ORD), federal agencies, states, tribes, and academic institutions. We also seek resources for Regional science needs, acknowledge our partners, and communicate our successes.

Regional Science Resources

The greatest science resources in EPA Region 9 are the science and engineering staff. Science and engineering staff work to bring sound science into the regulatory process on a daily basis. These scientists and engineers work together to accomplish multiple science related activities:

  • Communicating science issues and information to management
  • Engaging people at both staff and management levels on scientific priorities
  • Tracking science priorities and results
  • Stressing science as a critical element in decision-making
  • Strengthening partnerships with ORD and other Regions.
  • Communicating to ORD how the laboratory programs benefit our region
  • Helping to ensure that scientists obtain training
  • Identifying opportunities for regional scientists to provide regional training
  • Providing mentoring for regional science staff
  • Identifying and advertise science related opportunities for regional staff
  • Providing peer review/technical support/sounding board for scientists in the Regio

Science Team

The science team is composed of a Management Science Advocate, the Regional Laboratory Director, Quality Assurance Office Manager, Superfund and Technology Liaison (STL), the Regional Science Liaison (RSL), Regional Science Policy Advisors, and the Regional Science Council.

Regional Science Council

The Regional Science Council (RSC) provides focused leadership on science in Region 9. The members of the RSC include a representative and alternate from each Division. Representatives from the Science Team are members at large. The Council holds monthly meetings to discuss science activities and issues.

The council works with the RSL to determine Regional research needs, develop candidates for the Regional Research Partnership Program (RRPP), and assists with the solicitation and selection of grant recipients for the Regional Applied Research Effort (RARE ) and Regional Methods (RM) Programs. The RSC also sponsors seminar series, conferences, and workshops. Most recently sponsoring classes and seminar series on global climate change issues.

The Regional Laboratory

The Region 9 Laboratory (R9 Lab) provides analytical, technical and programmatic support at a regional level. That support is critical to accomplishing EPA’s mission of protecting human health and the environment. The R9 Lab provides a full range of routine and specialized chemical and biological testing of air, water, soil, sediment, tissue and hazardous waste for ambient and compliance monitoring as well as criminal and civil enforcement activities. In FY 2008, the R9 Lab performed over 11,000 analyses. In addition to fixed laboratory analytical support, the lab also provides field sampling and field analytical support.

The R9 Lab also has a significant role in relation to EPA’s Strategic Plan for Homeland Security. In order to enhance regional response capability and preparedness, the R9 Lab participates in several laboratory networks including the Interagency Laboratory Working Group (ILWoG); the California

Mutual Aid Laboratory Network (CAMALNet); the Environmental Response Laboratory Network (ERLN) and the Regional Drinking Water Laboratory Response Plan Network. In addition, the Region 9 Lab along with other regional labs provides technical and analytical support for EPA’s Office of Research and Development’s National Homeland Security Research Center’s (NHSRC) efforts to provide standard methods for agents related to homeland security incidents.

The Quality Assurance Office
