Ozone-generating Air Cleaners

o       Draft Air Cleaner Regulation Released for Comment.

The revised draft regulation to limit ozone emissions from indoor air cleaning devices has been posted at It would require all indoor air cleaning devices used in occupied spaces to be certified by ARB, based on passing a 50 ppb ozone emission concentration test protocol, with a few exceptions. Two public workshops were conducted, in March and June, to discuss the draft regulation and obtain comments. Written comments on the most current draft regulation are now due July 2,. In developing the draft regulation, we met with a number of groups such as Underwriters Laboratories, Inc., the Association of Home Appliance Manufacturers, and Intertek Testing Services NA, Inc., all of whom have provided much useful information. Additionally, UL has been very helpful in moving to complete the updated Clarification of their Section 37 ozone emissions test protocol and move it through the ANSI standards review process, so that it can be used for the ARB regulation. We anticipate taking the regulation to the September Board meeting for approval. Effective dates would be a September 30 manufacturing date, and a March 30, sales date.


o       Final Report on Ozone-generating Air Cleaner Survey.

On December 14th, ARBs Research Screening Committee unanimously approved the draft final report describing a telephone survey of more than 2,000 California households to determine the prevalence and use patterns of air cleaners in the State. The survey report is posted at: . An estimated 828,000 Californians reside in households where an air cleaner that intentionally generates ozone (ozone generator) is used (roughly 2% of all households), and are therefore at increased risk for exposure to ozone. Approximately 14% of all households in California own an air cleaner of some kind, and about a third of those households own more than one. In addition to the 2% of households with ozone generators, another 8% own ionizer or electrostatic precipitator type air cleaners that may emit lesser amounts of ozone as a by-product. The survey found that owners most often purchase air cleaners for health reasons; for example, there may be a family member with asthma or allergies living in the home. It was also learned that 80% of intentional ozone generator owners use their devices year-round, and 72% use them 24 hours a day. These findings are of particular concern given the potential exposure to children (present in 45% of all ozone generator households) and the levels seen in tests by the ARB and others (indoor concentrations as high as 300 400 ppb).


ARB-funded Field Studies

o       New Home Field Study.

In a study of the relationship between ventilation and indoor air quality, Indoor Environmental Engineering recently completed field sampling of over 120 new, single-family homes in northern and southern California in the summer, fall, and winter seasons. They measured indoor and outdoor pollutant levels of VOCs, aldehydes, CO, CO2, PM2.5, and NO2, and measured air exchange rates, HVAC operation, exhaust fan use, and window use. Levels of acrylonitrile and VOCs in the garage and home using canisters also were measured in a subset of homes. Preliminary results from the summer and fall monitoring are expected this month for internal review, and the draft final report is expected in the fall. This project is funded by CEC through PIER funds.


o       Indoor NO2 Monitor Field Measurements.

ARB staff recently completed field testing of a continuous indoor NO2 monitor in about 30 of the New Home Field Study homes in northern and southern California this winter. ARB previously funded the development of this prototype monitor by Battelle Laboratories to allow assessment of short-term, peak exposures to indoor NO2, for which there is a 1-hour, state ambient air quality standard. Preliminary data indicate that gas cooking, candle-burning, and perhaps nighttime furnace use or car operation produce elevated, peak indoor levels of NO2, but overall levels are relatively low.


o       Small & Medium Commercial Building Study.

In early March, ARB and CEC staff met with the investigators from UC Berkeley, LBNL, and UC Davis and an external advisory group to kick-off the Phase I contract to study IAQ and ventilation in small and medium commercial buildings (under 4 stories and less than 50,000 square feet). These types of buildings are the most common type of commercial building in California, but their IEQ and ventilation characteristics have been studied very little. Under CEC PIER funding, investigators will conduct a mail survey of building owners and managers regarding building characteristics, ventilation system characteristics, potential indoor pollutant sources, and IAQ in over 700 buildings statewide. The survey also will provide potential recruit buildings for the Phase II field study of IAQ and ventilation in 40 buildings. The kick-off meeting for the Phase II field study was held in April, and the investigators from UC Davis (Debbie Bennett) and LBNL (Mike Apte) have begun work to prepare for the field portion of this study. A wide array of measurements of ventilation, indoor air quality, and comfort factors will be obtained in the buildings.


o       Fact Sheet on Cleaning Products.

The indoor use of certain common cleaning products and air fresheners can cause an increase in indoor concentrations of gaseous and particulate pollutants. A fact sheet based on results discussed in the final study report, Indoor Air Chemistry: Cleaning Agents, Ozone and Toxic Air Contaminants, by Dr. Bill Nazaroff of UC Berkeley, is available at Findings indicated that when cleaning products were used in the presence of ozone, a high degree of reactive chemistry resulted. Measured reaction products from the terpene-ozone reaction included formaldehyde, ultrafine particulate matter, and hydroxyl radicals. Levels of formaldehyde and secondary organic aerosols produced from the reactions were significant when compared to health-based guidelines. However, there are many actions that can be taken to reduce exposures. See for the full study report.


We participated in a two-day symposium on research needs and priorities for indoor environmental quality (IEQ), which was sponsored and convened by Lawrence Berkeley National Laboratory (LBNL). The workshop focused on indoor exposures and health. ARB staff participated in panels on research priorities for IEQ in classrooms, and on opportunities and strategies for advancing IEQ research. Presentations from the workshop are available on the web at


We participated in a workshop sponsored by Lawrence Berkeley National Laboratory (LBNL) scientists to discuss and develop options to encourage California schools to purchase new heating, ventilating and air conditioning (HVAC) technologies. The new technologies developed by BARD are quieter, more energy efficient, and more effective at maintaining good indoor air quality than previous systems. ARB arranged for the use of a Cal/EPA auditorium for the workshop. See LBNL for more details, or Mike Apte, .


Peggy Jenkins, with Jed Waldman from DHS, presented information on Indoor Air Quality and Job Performance at the Green California Summit held in Sacramento March. They presented on studies that document the benefits of improving indoor air quality, including measurable improvements in the productivity of workers. Many vendors of green products, including low-emitting flooring and paper products, had displays and booths at the Summit.

Strategic Plan to Address Asthma in California. Staff across CDHS programs working to address asthma (EHIB, EHLB, OHB, plus the Chronic Disease Control Branch, Childrens Medical Services Branch, Childhood Asthma Initiative, Medi-Cal Policy And Financial Management Branch, and Medi-Cal Benefits Branch) are drafting the Strategic Plan for Asthma in California, in collaboration with numerous stakeholders across the state.  The  SPAC updates the Plan and contains five key goal areas to comprehensively address the public health burden of asthma. One goal area, Indoor Environments, addresses schools, childcare facilities, residential settings, and workplaces.  Separate sets of objectives and strategies are defined in the SPAC to specifically address each distinct environment. The Plan is expected to be issued early in the summer.


California Breathing (CB). This is a broad-based initiative to implement the state's strategic plan for asthma and is funded by a grant from the Centers for Disease Control. Program areas include asthma surveillance; education and training regarding asthma in schools and preschools; partnership building among asthma organizations, government agencies, coalitions, researchers and others to help reduce asthma in California; reducing disparities in asthma diagnosis, treatment, and prevention between population groups; and work related asthma policy investigations and education. See .

Asthma Surveillance. California Breathing is in the process of updating the County Asthma Profiles which are 1-page documents of county-specific asthma data for each of the 58 counties in California. First released in, the purpose of the Profiles is to provide local data for our local partners. We anticipate having data on outdoor air quality and air monitors per county in the new Profiles. Look for the Profiles in November. For more information on California Breathings Asthma Surveillance activities.

Housing Symposium. California Asthma Partners, a program of California Breathing, convened a symposium entitled Healthy Housing for California: Using Code Enforcement to Reduce the Impact of Asthma on December 8, . The first gathering of its kind, it brought together California asthma experts with professionals involved in housing code enforcement from around the state to learn from and strategize with one another. Over 70 people attended the meeting, representing cities and organizations from Los Angeles, Long Beach, San Diego, Fullerton, Fresno, Sacramento, San Francisco, Oakland/Berkeley, San Mateo County, Santa Rosa and other parts of the state.


Mini-Grants for Asthma. CB staff members are in the process of putting together a mini-grants program on asthma and housing. They will be awarding 5-6 grants of up to $15,000 in the fall of and. The grants will focus on multi-unit rental properties, especially those with a predominance of low income tenants. CB is also organizing a new advisory committee to help guide their work on housing.

Burden of Asthma in California. California Breathing surveillance report, The Burden of Asthma in California, is approved and ready for printing! The Burden Report is a comprehensive asthma data source book that provides information for asthma stakeholders to reduce the impact of asthma in California. There are a total of 19 sections, with ten data sections that include information on indoor asthma triggers and other risk factors associated with asthma. The report will be available on the CB website and hard copies are expected by the end of July.

U.S. EPA Grant. California Breathing, in partnership with RAMP and the Mendocino County Department of Public Health, recently completed a US EPA-funded project to build an asthma coalition in Mendocino County and provide educational workshops on environmental asthma triggers that commonly affect children.  Three workshops covered the following topics: outdoor air pollutants that impact people with asthma; indoor air quality in homes and other settings including child care; and indoor air quality in schools. Close to 120 people attended the workshops.


Starlight Tool Kit Trainings. Early in, California Breathing sponsored nine trainings across the state focused on increasing utilization of the Starlight Asthma Tool Kit for Schools (Tool Kit), a unique resource for schools designed to educate school staff about asthma and about asthma management in the school site. A key idea presented in the Tool Kit is that all staff have a role to play in reducing environmental triggers. As a result, the Tool Kit focuses special attention on describing strategies that improve indoor air and supports implementation of the U.S. EPA's Tools for Schools. By attending the training, school nurses were able to spend time discussing these strategies and ways to communicate their importance to other school personnel.  Almost 300 people participated in these trainings.


Mini Grants to address Asthma Disparities Among African Americans. Two projects funded by California Breathing's Mini Grant program focus on indoor air quality issues.  INMED/Mothernet LA is providing home assessments as part of their case management to their enrolled families for this round of mini grants.  Healthy African American Families II is being funded to work with property owners to develop and distribute a toolkit aimed at educating property owners on asthma triggers in home environments, specifically multi-unit housing.

The New State Department of Public Health. On July 1, the State Department of Health Services is being reorganized to elevate the visibility and importance of public health issues in the policy arena. The result will be creation of a Department of Public Health. The remaining programs will be consolidated in a Department of Health Care Services to increase accountability and improve program effectiveness for the public health and health care purchasing functions of state government. The mission of the Department of Public Health (CDPH) will be to protect and promote the health status of Californians through programs and policies that use population-wide interventions. Core functions in the new CDPH will include: Emergency Preparedness; Communicable Disease Control; Chronic Disease and Injury Prevention; Laboratory Sciences; Environmental and Occupational Health including Drinking Water, Environmental Management, Food, Drug and Radiation Safety; Health Statistics; and Health Facility Licensure and Certification. Look for our web site under as well as new email addresses starting soon.


Collaborative for High Performance Schools (CHPS). A face-to-face CHPS meeting was held in Sacramento on February 6th to organize and brainstorm changes for the upcoming CHPS Volume III Best Practices Manual. There was an IEQ Sub-committee breakout workgroup that discussed broad ideas for future direction. A parking lot of ideas was recorded and a subset presented to the Full Tech Committee as priority. Highest priority included devising notes for EQ 2.2, the low emitting material credit, to enable credits to be given for cabinetry, and teacher student desks and chairs and for office furniture in principal offices. Listed as priority were:

        Credit option for other HVAC systems that have additional environmental features in addition to providing ventilation minimum (EQ 2.1);

        Deck-to-deck partitions and separate exhaust for wood shops in schools (EQ 2.3);

        Provision for CO2 monitors and for window open indicators (perhaps in EQ 4.0);

        Increasing the stringency of the filtration requirements (EQ 2.0 P3 and EQ2.5).


There was also interest in considering improving criteria for paint to address carcinogens/ repro-toxicants as addressed in the Green Seal certification program and to consider acute exposure considerations. Additionally, the Full Tech committee asked the sub-group to consider adding green cleaners.


BIFMA Sustainability Standard. A two day BIFMA Sustainability Assessment Standard Stakeholder meeting was held on Tuesday, January 9 . The Human and Ecosystem Health Technical Workgroup presented among other credit language for two Furniture Emission Credits, 7.6.1 and 7.6.2. Credit 7.6.1 is aligned with the USGBC criteria (TVOC, Total aldehydes, formaldehyde and 4PC); and BIFMA SAS Credit 7.6.2 is aligned with the criteria found in the State of California bid specification referencing the Bid Specifications Appendix list of maximum acceptable individual VOC limits that are the CREL limits. Both 7.6.1 and 7.6.2 were structured and agreed upon by the workgroup to require testing using the BIFMA M7.1 as the core test protocol. The committee includes members from Steelcase Inc., Herman Miller, Interface Fabrics, Victor Innovatex, NAIMA, US EPA, MI DEQ, Northern Virginia Community College, Cal/EPA OEHHA, and CARB.


Emission Testing for Formaldehyde from Composite WoodA CARB Stationary Source Division contract to collaborate through an interagency agreement is in its final signature step at DGS.  The contract includes CDHS-IAQ assisting in testing composite wood products for formaldehyde emissions in support of their proposed airborne toxic control measure (ATCM) to reduce formaldehyde emissions from composite wood products.   And in assisting in certifying CARBs small test chambers to be used for their routine testing of wood products as part of enforcement of the ATCM.  In particular testing will include:  

1.      Assisting CARB in defining a small chamber test method to identify non-compliant products for enforcement of the ATCM  CDHS will compare large chamber test results to small chamber test results to establish a correlation factor.   

2.      Assisting CARB in developing a test to identify non-compliant finished goods CDHS will compare small chamber test results of a raw board versus boards laminated on one-side to establish a correlation.     

3.      Assisting CARB in determining test preparation steps for finished goods, CDHS will investigate how varying amounts of surface layer removal affects the rate of formaldehyde emissions for particleboards. 

4.      Assisting CARB in developing a field screen test CDHS will compare and correlate testing results from the FLEC test compared to the small chamber test. 

5.      Assisting CARB in quality control assessments of chamber testing, CDHS will participate in a round robin for comparative testing of raw boards with other certified labs, organizations and manufacturers performing large and small chamber tests.

Commissioning the CDHS-IAQ Environmental Chamber. We are in the process of the commissioning the DHS-IAQ large room sized chamber to meet the research requirements for multiple projects. Currently, we are modifying the operation of the facility according to ASTM Standard E1333 (American Society for Testing and Materials).


The large room chamber is constructed of inert, smooth surfaces with stainless steel. All joints and openings are sealed. All seals are made of non-VOC emitting and non-VOC adsorbing/absorbing materials. The air within the chamber is free of any obstructions or contamination such as humidifiers or refrigeration coils. Internally mounted fan is used to keep the chamber air well mixed. The internal chamber air only comes in contact with inert materials. We did a series of background VOCs sampling to confirm that the surfaces and seals of the chamber are sufficiently clean. Air concentrations were measured for individual VOCs <10 g/m3 and for formaldehyde at the levels below 3 g/m3 (2 ppb). We plan to do additional measurements to verify that the surfaces are chemically inert, i.e., chemicals are not lost to the walls or are re-emitted over time.


Air is supplied to the chamber using a single pass system. The target air exchange rate for the chamber is 0.5 0.05 air changes per hour (ACH). To control the air flow rate, we can vary the speed of supply and return air fans and the opening status of dampers. Chamber air exchange rates are calculated from tracer gas decay measurements. An inert tracer gas (SF6) is introduced into the chamber with the inlet air over a short period of time (1 to 10 min). The chamber air concentration of the tracer gas is then measured over time at two or three locations within the chamber. The current configuration of the ventilation control system has made it a challenge to make direct flow measurement, given the low target rate (10 cfm). The inlet air supply to the chamber will be monitored continuously and maintained at a constant temperature and humidity of 23 2 C and 50 5% RH. We are also working on the automatic control of the system and data logging. Below are the Specifications for the Environmental Chamber:

Tire Derived Flooring Study. The release of the Study Final Report was delayed to address comments raised by the projects Advisory Group. The new release date is expected in early July.


Definition of VOC for Paint Certification. The Canadian eco-label Terra Choice accepted CDHS recommended comment to modify the definition of VOC in their Paint certification (CCD 166). The former definition was:

VOC means volatile organic compound and is any organic compound which participates in atmospheric photochemical reactions to create smog. It excludes those organic compounds which the ECP designates as having negligible photochemical reactivity.


The revised list of indoor VOCs is broader, as follows:

VOC means volatile organic compound and is any organic compound which participates in atmospheric photochemical reactions to create smog and / or contribute to poor indoor air quality. VOCs include carbon containing compounds (excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides and carbonates and ammonium carbonate) with vapor pressure >0.01 KPa at 20C.


Ventilation Standards in CA Title 24. In May, Leon Alevantis submitted comments to the California Energy Commission on their proposed Multiple Zone System Demand Controlled Ventilation (DCV) for the Energy Code revision. He raised concerns about height, commissioning, and maintenance requirements for CO2 sensors. He also requested that CEC prohibit DCV in high occupancy applications, such as call centers. Cal/OSHA staff submitted written comments regarding DCV proposals.

Cosmetics and Hazardous Chemicals. The California Safe Cosmetics Act of is a law designed to assist consumers and workers who use cosmetic products in getting information about potentially hazardous chemicals contained in these products. The Act requires cosmetics manufacturers to disclose to the California Department of Health Services all products that contain ingredients known to cause cancer or birth defects and other reproductive harm. The California Safe Cosmetics Program (CSCP) was established to collect this information and make it available to the public and is managed OHB. The DHS (CDPH) Division of Food, Drug and Radiation Safety is responsible for enforcing the provisions of the Act.


This information will allow workers, employers, and consumers to make informed decisions about products they purchase and use. All users could potentially benefit if manufacturers voluntarily remove hazardous ingredients from their products. The program will also convene meetings of health advocates, manufacturers, regulators, and other interested parties to promote collaborative efforts to improve product safety.


Developing a Regulation to Protect Workers from Exposure to Heat Indoors. The OHB has been working with others in DHS and Cal/OSHA to track heat fatalities, both occupational and residential, and to determine associated factors. This effort is in support of Cal/OSHAs development of regulatory proposal designed to protect workers from heat illness in indoor environments. Inclusion of office workers in the scope of the proposal is a possibility. A regulation protecting workers outdoors went into effect in.


New Publications

N-Methylpyrrolidone (NMP) is an unregulated solvent that was developed to replace methylene chloride and other solvents that harm the environment. It is used in an increasing number of paint strippers, graffiti removers, and special-purpose cleaning products. HESIS has published the Advisory to warn that NMP may be toxic to the developing fetus and may reduce fertility in men and women. The Advisory lists products that contain NMP and safer substitutes that protect workers, consumers, and the environment. This publication was developed as a part of an EPA Pollution Prevention grant-funded project.


Methylene chloride is a solvent that can harm the brain and the heart, and cause cancer. It also contributes to air pollution. The fact sheet lists products that contain methylene chloride, and describes how it is used in specific job tasks and industries. The publication describes safer alternatives that protect workers and the environment, as well as basic requirements of the comprehensive Cal/OSHA methylene chloride standard.


The HESIS has issued a Health Hazard Alert to warn workers, employers and health care providers about the dangers of diacetyl, a chemical used in many food flavorings.  Exposure to diacetyl can cause bronchiolitis obliterans, a serious lung disease that can result in permanent lung damage and even death.  Workers from two California flavoring companies that use diacetyl have already been diagnosed with this disease.  The Hazard Alert provides information on how workers can be exposed to diacetyl, symptoms and health effects workers may experience, prevention measures and resources.


This new edition of the popular factsheet highlights changes made to the Cal/OSHA Sanitation Standard to address mold hazards and provides up-to-date resources for workers and employers. The factsheet explains the health effects of mold, how to know if mold is present, and what to do if you find mold in your workplace.  Special audiences include teachers, office workers and others who work in indoor environments and their employers.

Multi-Unit Housing Workgroup. The workgroup continues to meet monthly to assist in the development and implementation of strategies to increase the number of voluntary and legislative policies related to smoke-free multi-unit housing in California.  Activities include planning and conducting technical assistance calls, and developing media and resources.  The calls occur approximately every three months, and the November call addressed: How to speak with callers who complain about SHS drifting into their home, and the February call: Reaching out to the housing industry:  Market rate and affordable housing Joanne-Wellman Benson and Esther Schiller represented California at the National Smoke-Free Multi-Unit Housing Forum in Michigan, November.  


Latino Renters Survey.

In September, the Hispanic/Latino Tobacco Education Partnership and the American Lung Association of Californias Center for Tobacco Policy and Organizing jointly released Latino Renters Survey: Attitudes about Secondhand Smoke in Apartments. The results from the first-ever survey of Californias Latino renters shows high rates of drifting smoke exposure.  Despite 95 percent of Latino families banning smoking inside their apartments, 63 percent of respondents have been exposed to secondhand smoke drifting into their apartment.


Secondhand Smoke Media. California Department of Health Services released a comprehensive package of anti-tobacco advertising, including ads exposing the dangers of drifting secondhand smoke in multi-unit housing. Media forms include, television, radio and print ads targeting Asian/Pacific Islander, Hispanic/Latino, African-American and general market audiences. Several ads address drifting tobacco smoke in apartments as a health risk.


Workplace Smoking Policy. Assembly Bill (Oropeza) was signed by the Governor in September .  The bill amends Government Code (Section 7596) and Labor Code (Section 6404.5) in order to clarify the smoking banned in the following places of employment:  lobbies, lounges, waiting areas, elevators, stairwells, and restrooms.  AB also includes buildings attached to parking lot, although the parking lot itself remains exempt from the prohibition.


Anti-smoking Legislation. Newly-elected State Senator Jenny Oropeza introduced two anti-smoking bills in December: SB 4: No Smoking at State Parks and Beaches, would establish a fine of $250 for smoking at a state beach or within a state park. The measure includes public posting of the ban.  And SB 7:  No Smoking in Cars with Children, would make it an infraction for a person to smoke in any car with a child younger than the age of 18 in it, even if the car was parked or on private property. 


Secondhand Smoke Policy Database. A Prop 99 funded agency, The California Clean Air Project () has developed a secondhand smoke policy database with an extensive collection of ordinances, statewide laws, and selected voluntary secondhand smoke policies in California.  The database is searchable both by county or topic. 


Housing Tax credit: Language is being proposed by the Tax Credit Allocation Committee to include 1 point on developers applications to include non-smoking sections in apartments. The proposed language (January 18,) is given as:




The proposed project will contain nonsmoking buildings or sections of buildings.  Nonsmoking sections must consist of at least half the units within the building, and those units must be contiguous. 1 point


To receive these points, the applicant and the project architect or mechanical engineer must certify in the application, which of the items will be included in the projects design and specifications, and further must certify at the projects placed-in-service date that the items have been included and/or that the energy efficiency standard has been met or exceeded. Projects receiving points under this category that fail to meet the requirement will be subject to negative points under Section 10325(c)(3) above.


The proposed regulations for the CTCAC application process do not change or delete the availability of this point.  In, CTCAC had a total of 150 applicants for the tax credit.  Of these applicants, 43 utilized the available smoke-free housing point.  Of the 150 applicants, only 60 were awarded the tax credit.

Report on health risks related to play surfaces made from recycled waste tires.. OEHHA recently finished a study to explore the potential health risks to children of using outdoor playground and track surfaces constructed from recycled waste tires. These types of play surfaces are also used in indoor gymnasiums and playgrounds. The study was conducted under contract with the California Integrated Waste Management Board (CIWMB). The Janurary report, Evaluation of Health Effects of Recycled Waste Tires in Playground and Track Products is available online: . Other tire-related publications are also available on the CIWMB web site:


Health Criteria for School Site Risk Assessment. California Health and Safety Code Section 901(g) requires OEHHA to evaluate and publish, as appropriate, numerical health guidance values for those chemicals that could be encountered at school sites and may adversely impact the health of school children. The latest reports are on (a) Manganese and pentachlorophenol, and (b) Blood lead,


Investigation and Cleanup of a Residential Complex. OEHHA conducted an examination of remedial actions used in the investigation and clean-up of the Midway Village Residential Complex in Daly City, CA. The objective was to determine whether these actions were adequate to fully protect the health of residents. The evaluation included human health risk assessment, and review of state and federal guidelines for management of health risks at properties contaminated with hazardous chemicals. The OEHHA review was issued in July, and updated in October. It is available at:

Recognition, Management, and Reporting of Pesticide Illness. OEHHA, with Department of Pesticide Regulations, and the Center of Occupational & Environmental Health (UC), and California Office of Bi-national Border Health (CDHS) prepared a 60-minute training course, primarily designed for physicians and nurses.  It defines the terms "pest" and "pesticide"; presents an overview of pesticide types; defines "pesticide illness"; and provides guidance on how to recognize and manage commonly encountered pesticide illnesses. It also presents case examples and outlines reporting requirements for medical providers. The course can be accessed for free at: .


Di(2-ethylhexyl)phthalate (DEHP). Effective September , the Proposition 65 Maximum Allowable Dose Levels MADLs for DEHP by the oral route of exposure have been set at 410 micrograms/day (μg/day) for adults, 58 μg/day for infant boys and 20 μg/day for neonatal boys. These values are based on the male reproductive effects of DEHP observed in animal studies. As specified in regulation, when the applicable reproductive effect is upon the male, the MADL is calculated based on a human body weight of 70 kg. Accordingly, age-specific MADLs have been calculated for infant and neonatal boys based on body weights of 10 and 3.5 kg, respectively. DEHP is mainly used as a plasticizer of polyvinyl chloride (PVC) in the manufacture of a wide variety of consumer products for building construction, automobiles, home, clothing, toys and medical devices.

IAQ Tools for Schools Activities. The EPA Region 9 Indoor Environments Team has been working with a variety of new and continuing partners on often multi-partner activities to advance implementation of IAQ management plans in California schools. Highlights of these activities follow.

        Schools/CAFA and/or CTA project. Shelly Rosenblum provided "Tools for Schools" (IAQ TfS) trainings for members of the Sonoma and Solano County Asthma Coalitions, including maintenance/facilities managers from the Fairfield-Suisun, Vallejo and Vacaville school districts.

        Oakland USD. Barbara Spark participated in a meeting at the OUSD teachers union office to discuss how the Oakland Education Association (OEA) could work with asthma partners and EPA to improve IAQ and asthma awareness at the district, as well as further implementation of the IAQ Tools for Schools program. The meeting was arranged by Mindy Landmark of the CAFA Coalition based at the Ethnic Health Institute. Participants included OEA President Betty Olson-Jones and Executive Director Ward Rountree, Janis Nielsen, coordinator of the CTA IAQ project, and Kate Lorenzen from RAMP/CAFA.

        Training for Tribes. The EPA sponsored American Lung Association's Tribal Hands-On Indoor Air Training is being held at the Hopland Tribe in California (Mendocino County) on May 21-25,. This course is aimed for homes built in mixed climates and is the second ALA training for Region 9 (the first was in Arizona). Funding for the training comes from a national EPA Grant to the American Lung Association Health House Project. Approximately 20 tribal environmental specialists from Northern California will be attending.  Participants are taught a wide range of effective, affordable, and efficient remediation strategies to address the major IAQ related problems of moisture and mold, combustion gases, leaky buildings, inadequate ventilation, particulate control, and radon. Indoor air quality problems, especially mold and moisture are becoming bigger problems in tribal housing, mostly due to inadequate building construction.

        San Diego USD and Montebello USD. Barbara Spark participated in two events/meetings with key decision-makers at these Southern California school districts on February 16 and 20,. At San Diego USD, she participated in a half-day workshop on "shared decision-making," attended by principals and teachers' union site representatives. Expectations are that IAQ Tools for Schools will be launched at the district inn the new school year within this collaborative process. At Montebello USD she participated in a launch/planning meeting for TfS with the Maintenance and Operations Director, key staff, and the teachers' union Executive Director.

        Presentation to state legislators. Barbara Spark provided a detailed talk on IAQ Tools for Schools and EPA's Healthy SEAT program - and the reasons why school districts do or don't adopt these programs - at the Council of State Government (CSG) health policy forum, "Asthma and Respiratory Health: Policy Approaches to Create Asthma-Friendly Environments, May 3-5, in San Diego. The very engaged audience included seventeen state senators and representatives from fifteen states and territories. They asked a lot of questions about mold.

        New publication on achieving improved school IAQ. Envisioning Excellence: Lessons from Effective School Indoor Air Quality (IAQ) Programs can be accessed from the web page:   Envisioning Excellence  helps schools take effective action to advance health, safety, and wellness initiatives. Envisioning Excellence  presents the Framework for Effective School IAQ Programs: Six Key Drivers--guidelines that detail the organizational approaches and practices that are fundamental to school IAQ program success--and presents five profiles in excellence to demonstrate how different school districts applied the Framework to create effective and enduring IAQ programs.

        Other TfS training. Among other such events, Shelly Rosenblum provided TfS workshops for the California Breathing project to help develop the Mendocino County Asthma Coalition; and well as the CAFA/S.F. Asthma Coalition TfS project at San Francisco USD.

IAQ Tools for Schools (IAQ TfS) National Symposium. Shelly Rosenblum and Barbara Spark attended the 7th Annual TfS Symposium in Washington, DC. December 7-9,. Thanks to scholarships from our HQ division, a number of key decision-makers attended the Symposium from the ranks of both California school district administration (including San Diego and Montebello USDs), and teachers unions, including the California Teachers Association (CTA) and the Oakland Education Association, resulting in significant commitments to move forward on TfS implementation. Shelly was the moderator for the plenary session on students and TfS.

National Education Association (NEA) Pre-TfS Symposium training.  Barbara Spark provided EPA's welcoming talk to more than 100 members of NEA at the all-day pre-Symposium training on December 6, in Washington, DC. Barbara provided a regional perspective, focusing on the value of unions' identifying the fears about Tools for Schools implementation on the part of district administrators, and addressing these barriers head-on by entering into a frank dialogue between management and unions, along with the unions offering to assist with TfS.  

IAQ Tools for Schools (IAQ TfS) National Symposium. Registration opens June 8, for this year's symposium, December 6-8, to take place in Washington, DC. The faculty will include representatives of seven Excellence Award winning school districts, including two from California: Saugus and Visalia. Attendance at this very successful annual event is capped at 500, so prompt registration is necessary to assure a place, at   Presentations from last year's event can also be viewed at that site.

EPA National Asthma Forum, May 31-June 1, Washington, DC. This is the follow-up to last years very successful initial offering. Award winners and new Forum materials will be posted at  

CTA Healthy Air Healthy Kids IAQ project. A major new player was added in October when The California Endowment awarded a grant to the California Teachers Association "Teachers for Healthy Kids" program to fund their new "Healthy Air, Healthy Kids" project.  In this statewide initiative, CTA will raise awareness of its members about school IAQ, and steps that they can take to avoid asthma triggers and encourage adoption of constructive IAQ policies and practices. IAQ Tools for Schools is included where Community Action to Fight Asthma (CAFA) coalitions are working on this objective. Along with RAMP/CAFA staff, we have been participating in the workgroup which is providing technical advice, as well as planning and helping to implement this project. Coordinators for CTA are consultants Janis Nielsen and Hellan Dowden.

EPA HealthySEAT. HealthySEAT Version 2 Beta is now available for testing and comment until June 20,.

EPA sponsored national asthma network. The Communities in Action for Asthma-Friendly Environments Network website,  has undergone substantial revision and upgrading. Seventeen California coalitions, organizations, and programs have joined the network.

Memorandum of Understanding to Reduce Health Risks from Secondhand smoke. The U.S. EPA and the U.S. Department of Health and Human Services (HHS) signed a Memorandum of Understanding (MOU) to improve the quality of life for Head Start and Early Head Start families nationwide. The MOU establishes a framework between EPA's Indoor Environments Division (IED) and the HHS' Office of Head Start (OHS).  The agencies intend to work together to conduct nationwide outreach to nearly a million families in an effort to deliver health risk reduction messages related to secondhand smoke and other environmental asthma triggers. Activities of the MOU can be read at:
