AB1173 Listserve and Workshop: Assembly Bill 1173 (Keeley,) requires the Air Resources Board, in consultation with other health and environmental agencies, to prepare a report on indoor air pollution. ARB has established a web page, , to keep the public informed of our progress and plans on this project. The web page currently includes a summary of AB1173 requirements, a link to the complete bill, a tentative schedule for developing the report and receiving public input, and access to the listserve. To register for this or other ARB listservs, please visit


Portable Classroom Study. The Research Screening Committee (RSC), an external peer review advisory group for ARBs research program, continued their review of Research Triangle Institutes draft final report on the Portable Classrooms Study (PCS) to their next meeting on April 29, because the February report was not yet completed. It is anticipated that a completed report will be reviewed and discussed at the RSCs April 29 meeting. Interested parties who have not yet signed up for ARBs PCS listserv should be sure to do so at


Re-thinking the Relocatable Classroom. Staff participated in a February meeting of state agency representatives convened by Southern California Edison (SCE) to review SCEs plans for their Phase II high performance portable classroom project, review design criteria, and identify potential opportunities for collaboration. The Phase II classrooms will be sited at a school in the Pomona District. Planning is scheduled for the next few months. The meeting served as a useful update for all involved. Peggy Jenkins, .


Economic Analysis of Costs And Benefits of Sustainable Buildings. Staff commented on the human health and productivity benefits and the outdoor air quality benefits in the draft report on Economic Analysis of costs and benefits of sustainable buildings. This report was prepared for ARB and several other Sustainable Building Task Force members.


Indoor Cooking Emissions. Staff assisted with draft press releases issued by ARB warning Californians of hazards of indoor CO and indoor cooking emissions (see ), and explained how to reduce those hazards. Keeping appliances properly tuned and maintained and using good ventilation are two of many actions people can take to reduce combustion pollutant exposures, which can be higher during winter.


Fuel Cell for Christmas Lights. Staff assisted the Governors Office of Planning and Research with set-up of a portable fuel cell to light LEDs on a Christmas tree in the courtyard of the Cal/EPA building. Indoor air quality issues were considering because the manufacturer initially proposed operating the unit in the lobby of the building.


Environmental Technology Verification (ETV) for Improved Exposure Monitors. At a January 30-31 meeting of the Air Stakeholders Committee for the U.S. EPAs Environmental Technology Verification (ETV) Program, staff presented information on ARBs past and current projects to develop improved indoor air and personal exposure monitoring equipment, and discussed current needs in this area of technology. The ETV stakeholders include representatives from local and state air pollution agencies, industry, and others. The meeting was coordinated by Battelle, which manages the Advanced Monitoring Systems Center for the ETV program. This part of the ETV Program provides an opportunity for third party testing and verification of the performance of air pollution monitoring technologies. Staff discussed RDs previously sponsored projects to develop portable, real-time nitrogen dioxide and ozone monitors for use in indoor air quality and health study applications, and the current effort under ARBs Innovative Clean Air Technologies Program to support the development and demonstration of new, user-friendly monitoring technologies.


Fresno Asthmatic Childrens Environment Study (FACES). The Air Resource Board voted in December to continue funding for FACES. The UC Berkeley investigators are about mid-way through the work originally planned. The study is an epidemiology study of more than 200 children with asthma to examine both the immediate and long-term effects of air pollutants on childrens asthma. One of its many strengths is that the study includes some of the most extensive exposure assessment ever conducted for such an epidemiology study, which should improve the investigators ability to identify possible relationships between exposure to air pollutants and the progression of asthma in the children. A one-year field effort to measure pollutants, potential asthma triggers and various home conditions (called the Home Intensive) in a subset of participants was completed in February.

BASE Study. Derek Shendell has started working with IAQS staff (I mean, Dr. Shendell). An immediate effort will be to combine results originally in separate files into a single file with bioaerosol measurements by building. We plan to start collaborating with the LBNL-IED group to link moisture-indicating microorganisms with symptoms and descriptive evidence of microbial contamination. Abstracts on BASE research results have been submitted for APHA and the Sarasota Springs Bioaerosol Conference.


Environmental Tobacco Smoke (ETS) Study. We have completed the filed study at a non-smoking office building with a designated smoking room in Las Vegas. We have completed the analyses of the data from this field study as well as the CATS data. The final report for this research study is due to TRDRP by August 31st.


Emissions of Building Materials With High-Recycled Contents. The CIWMB funded DHS to conduct a study to measure emissions of building materials with high recycled -content compared to "standard" products. The study includes three phases on products used in school classrooms, state office buildings, and tire-derived [flooring] products. The final report is due in April.


Indoor Air Quality Testing at the Capitol East End Complex.. The IAQ Section conducted side-by-side sampling with the Block 225 contractor during the last IAQ sampling. The DHS-IAQ Section is planning to continue sampling of the indoor air of Block 225 and Blocks 171-174 after occupancy. We are anticipating that we will receive a grant from the U.S. EPA to partially fund this activity.

News Conference Celebrating Californias Successful Smoke-free Work Place Law. On November 20, , the National Conference on Tobacco or Health hosted a news conference in San Francisco celebrating the anniversary of Californias Smoke-free Workplace Act. January 1, marked the eight-year anniversary of smoke-free indoor workplaces and restaurants and the five-year anniversary of smoke-free bars.


At the news conference, State Health Director Diana M. Bont, R.N., Dr.P.H. unveiled two opinion polls conducted in Fall and commissioned by the California Department of Health Services that show overwhelming support for smoke-free bars by bar owners, employees, and patrons.


Some key findings of the bar establishment survey included:

        The majority (77 percent) of bar managers and employees surveyed said a smoke-free environment inside their bar is very or somewhat important to them, compared to 53 percent of those surveyed in.

        The majority of bar managers and employees (77 percent) said complying with the law has been very or fairly easy.

        More than eight in 10 bar managers and employees (83 percent) surveyed said they think the smoke-free workplace law protects their health and the health of other bar employees, while only 15 percent think it does not.


Some key findings of the bar patron survey included:

        The majority of bar patrons (87 percent), including smokers (71 percent), said they are more likely to visit bars, or have not changed their bar-going behavior as a result of the law.

        In, 75 percent of bar patrons surveyed said they approve of the law, compared to 59 percent surveyed in. Even among smokers, support of the law has nearly doubled, increasing from 24 percent in to 45 percent in.


More than 100 media outlets throughout California and the United States covered the news story. Materials developed for the press conference have been reorganized into a Secondhand Smoke (SHS) Update. Available in April, the new issue includes the Fall, Field Poll data on bar owners, employees, and patrons; an interview with Terry Friedman (original author of Assembly Bill [AB] 13); information on the economic impact of AB 13; and, a timeline of SHS activities in California.


Tobacco Education and Research Oversight Committee (TEROC) Master Plan. TEROC released their Master Plan for the Tobacco Control Program for . Of their 6 objectives, one is to decrease exposure to secondhand smoke. Recommended strategies for achieving this are to: 1) continue to educate the public on the health effects and on the tobacco industrys efforts to deny these effects; 2) pass restrictions at the local level eliminating exceptions and expanding protections found in Labor Code 6404.5, the California Smoke-free Workplace Act; 3) pass restrictions on outdoor smoking, such as for building entry ways, college campuses, health facilities, prisons, fair grounds, amusement parks, concerts, and sporting events; 4) promote voluntary home/car smoke-free policies; 5) ensure consistent local compliance and enforcement of state and local smoke-free workplace, school, and outdoor area laws; enhance protections through voluntary smoke-free policies to protect residents in multi-unit housing; 6) require the Department of Alcoholic Beverage Control to assist in enforcing the smoke-free bar law; 7) educate policy makers that ventilation technology is not effective in controlling secondhand smokes health effects; 8) conduct research on indoor and outdoor secondhand smoke exposure.


Live, Work, and Play Smoke-free Campaign. The Tobacco Control Sections Secondhand Smoke Workgroup is developing a secondhand smoke campaign that will assist in maximizing compliance with existing smoke-free workplace laws and expand protection from secondhand smoke exposure within indoor and outdoor areas where people live, work, and play. The campaign will focus on the collection of existing strategies, policies and other supportive educational and promotional material that can be implemented at the local level to facilitate adoption of secondhand smoke policies. The end product will be a website and training for TCS-funded projects by early.


Secondhand Smoke-Related Bills Recently Introduced.

        AB 210 (Nation)- Smoking in and near residential dwellings. It has three provisions that place limitations on the smoking that can take place in and around residences.

A)    It defines drifting, wafting, or blowing smoke as a nuisance within common interest developments, with some exceptions.

B)     It prohibits smoking in the indoor and outdoor common areas of multifamily residential housing.

C)    By January 1, it would prohibit smoking in units of multifamily residential housing, except those units that have been specifically designated by a landlord as units where smoking is permitted.

        AB 384 (Leslie)- Prohibits tobacco products in prisons and the Youth Authority. It prohibits the Department of Corrections (DC) and the Department of the Youth Authority (DYA) from selling tobacco products to persons confined in their institutions. AB 384 also requires the DC and the DYA to adopt regulations prohibiting the possession of tobacco products by inmates.

        AB 846 (Vargas) - Expands the smoke-free perimeter around state-owned and leased building entrances and exits and city and county buildings. It amends the existing smoke-free distance from the entrances and exits of state-owned and leased buildings from 5 feet to 20 feet.

Revision of the Sanitation standard, GISO 3362. The new subsection (g), now in effect as of September 4, is as follows:


Title 8, Calif. Code of Regulations; General Industry Safety Orders: Article 9 Sanitation

3362. General Requirements.


(g) When exterior water intrusion, leakage from interior water sources, or other uncontrolled accumulation of water occurs, the intrusion, leakage or accumulation shall be corrected because of the potential for these conditions to cause the growth of mold.


IAQ Advisory Committee. The first meeting was held on November 20, in Oakland. The meeting included a presentation by the California Energy Commission on the proposed changes to the California Energy Code regarding Demand Control Ventilation (DCV). The latest draft proposal would make it mandatory for some classrooms and additional assembly occupancies, and would raise the carbon dioxide set point from 800 to 1100 (or 700 above outside CO2). A discussion of the potential effect of utilizing DCV in school buildings followed. CEC has been preparing the proposed changes for the formal rulemaking process that will begin in early. Possible revisions to General Industry Safety Orders 5142 and 5143 were also discussed.


A second meeting was held on March 6,. Attendees discussed the modified proposal for the use of DCV that CEC plans to submit for rulemaking within the next few weeks. Attendees also discussed suggested changes to Title 8, Section 5142. The modifications are intended to address problems in identifying the entity that can make changes to a HVAC system in a workplace. Another meeting will be held later this year.



Airborne Contaminants: 8CCR 5155. The Division is continuing to review Threshold Limit Value changes proposed by the ACGIH. The first meeting of the advisory committee was on May 4,. Another meeting will be scheduled soon. The Division coordinator is Bruce Wallace who can be reached.


Laboratory Fume Hoods: 8CCR 5154.1. The Division has convened five advisory committee meetings to evaluate two different petitions requesting the Standards Board to reduce ventilation rate requirements and establish a performance standard in place of the existing regulation that relies on face velocity measurements. The last meeting was on August 8th in San Francisco. Another draft proposal was presented and discussed by the attendees but no final proposal was adopted. A revised proposal has been circulated to the members of the committee. The Division coordinator is Bruce Wallace who can be reached at .


Heat Stress Standard. The Division has held three advisory committee meetings to review the need and issues involved in proposing a standard for heat stress. The last meeting was on February 15, in Oakland. A draft proposal was reviewed at the meeting, and revisions will be forthcoming based on the outcome of the meeting.

School Sites. OEHHA has made available the first Draft Guidance for Assessing Exposures and Health Risks at Existing and Proposed School Sites. This draft guidance document was prepared to comply with California Health and Safety Code Section 901(f), which requires OEHHA to develop and publish a guidance document for use by the Department of Toxic Substances Control and other state and local environmental and public health agencies to assess exposures and health risks at existing and proposed school sites, and including child-specific routes of exposure unique to the school environment, in addition to those in existing exposure models. The draft document was posted on the OEHHA Web site on December 20 ; see . A one-day public workshop was held on January 24, to discuss the scientific basis of the proposed guidance document.


Hot Spots Toxicity Equivalency Factors. OEHHA released a draft document, Proposal for the Adoption of the Revised Toxicity Equivalency Factor (TEFWHO-97) Scheme to solicit public comment. This draft document has been developed by OEHHA for use in implementing the programs for Toxic Air Contaminants and Air Toxics Hot Spots. Chlorinated dioxin-like compounds are widespread and persistent environmental contaminants, emitted by various combustion processes, which are suspected of causing cancer and other adverse health impacts. In, the California Air Resources Board identified chlorinated dibenzo-p-dioxins and dibenzofurans as toxic air contaminants, and OEHHA determined a cancer potency value for 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The cancer potency for other dioxin-like congeners varies according to their chemical structure. Toxicity Equivalency Factors (TEFs) are numerical factors that express the toxicity of an individual dioxin-like compound relative to the toxicity of TCDD. The original International TEFs were developed by a group of scientists convened by the World Health Organization (WHO). These are used in the Air Toxics Hot Spots Program to evaluate the cancer risk due to exposure to mixtures of chlorinated dibenzo-p-dioxins and dibenzofurans. More recently, WHO has sponsored revisions of the original TEF table, in order to reflect new data and improved understanding of the nature and mechanisms of toxicity of dioxin-like compounds. Chlorinated dioxins and dibenzofurans were recently identified as priority chemicals for evaluation of their impact on children's health under the Children's Environmental Health Protection Act (SB25). OEHHA proposes that the revised version of the TEF scheme (TEFWHO-97) should be adopted for use by the Toxic Air Contaminants Program. Following the public comment period, the document and any comments received, along with OEHHA's response to these comments, will undergo review by the state's Scientific Review Panel on Toxic Air Contaminants. The draft can be found on-line at .


Hot Spots Cancer Potency Factors. The Technical Support Document for Describing Available Cancer Potency Factors (TSD) contains cancer unit risks and potency factors for 121 of the 201 carcinogenic substances or groups of substances for which emissions must be quantified in the Air Toxics Hot Spots program. The purpose of this document is to provide a summary of the data supporting the carcinogenic potential of the substance or group of substances and to provide the calculation procedure used to derive the estimated unit risk and cancer potency factors. This document has been revised from the April version; link to it on-line at . You can download just the table of Hot Spots Unit Risks and Cancer Potency Values at


Wildfire Guide A Guide for Public health Officials. This document was written the California Office of Environmental Health Hazard Assessment, the U.S. Environmental Protection Agency; and the Missoula County Health Department, with input from individuals in several other state and federal agencies, in particular the California Department of Health Services, the California Air Resources Board, and editorial support Washington State Department of Health. It was developed in part as a result of a workshop held at the University of Washington in June, under the auspices of the U.S. Environmental Protection Agency, Region X, and the Department of Environmental Health, School of Public Health and Community Medicine of the University of Washington. The Wildfire Guide (27 pp) is on-line at: .


Proposed Public Health Goals for Drinking water. Chemicals present in drinking water can impact indoor environments due to their use in cleaning and washing (baths, showers, dish washings, etc), laundry, and other activities. OEHHA has released draft Public Health Goals (PHG) for Arsenic and Chromium 6.


        Arsenic in Drinking Water. OEHHA has released a draft Public Health Goal (PHG) for arsenic in drinking water. The draft PHG proposes to identify 4 parts per trillion as a level of arsenic in drinking water that would not be expected to pose a human health risk. In developing the draft PHG, OEHHA conducted an exhaustive analysis of all available scientific studies on the health effects of arsenic. The proposed PHG of 4 parts per trillion is based upon studies of hundreds of thousands of patients in Taiwan, Chile and Argentina with lung and bladder cancers associated with elevated levels of arsenic in drinking water. OEHHA estimates that a level of 4 parts per trillion of arsenic in drinking water would cause not more than one additional cancer case in a population of one million people drinking two liters of water daily for 70 years. OEHHA will hold a public workshop to accept public comments on the draft document on May 2, in Oakland. OEHHA will also accept written comments on the draft document until May 2,. Arsenic is found naturally in air, water, soil, mineral deposits, and food. While arsenic in water typically is naturally occurring, the improper disposal of waste chemicals can also contaminate water supplies with arsenic. Long-term exposure to arsenic in drinking water can increase the risk of lung and bladder cancer and, to a lesser extent, increase the risk of skin, liver and kidney cancer. Other serious health effects stemming from long-term ingestion of arsenic in drinking water include heart attacks, stroke, diabetes mellitus, high blood pressure, liver and nerve damage, abnormal skin growths, and some reproductive and developmental problems. The existing state and federal drinking water standards for arsenic have been set at 50 parts per billion for many years. A new federal arsenic standard of 10 parts per billion will take effect in. A legislative bill authored by Senator Don Perata and enacted into law in. The Draft PHG for Arsenic in Drinking Water is on-line at


        Chromium in Drinking Water. OEHHA in November withdrew its Public Health Goal (PHG) for chromium in drinking water. The PHG, adopted in February, was 2.5 parts per billion (ppb). OEHHA and DHS are committed to develop the nation's first drinking-water standard for chromium 6, also known as hexavalent chromium. The chromium 6 PHG, which OEHHA will develop by Spring, will replace the withdrawn PHG for "total" chromium, which consists of both chromium 6 and a less-toxic form of the metal, chromium 3. A University of California report released recently has been under attack. Senator Ortiz, who sponsors legislation (senate Bill 351) to require the state to adopt chromium 6 standard by January, is seeking to have the report thrown out. There are allegations that the state-mandated blue ribbon panel that prepared this report was manipulated to favor corporate interests. See report from LA Times at


East Bay Childrens Respiratory Health Study. Two manuscripts are prepared for publications: one on the East Bay Children's Respiratory Health Study and the second on the statewide assessment of school proximity to busy roads. For East Bay Kids, we are still validating the data analysis, but we are seeing increased respiratory outcomes in children attending schools with higher pollutant measurements.


Proposition 65 Carbon Black. OEHHA is adding carbon black (airborne, unbound particles of respirable size) to the list of chemicals known to the State to cause cancer for purposes of the Safe Drinking Water and Toxic Enforcement Act of (Proposition 65). The listing of carbon black is effective February 21,. The listing only pertains to airborne, unbound carbon black particles of respirable size. OEHHA and the California Air Resources Board have also noted that, "In general, particles 10 m or less in diameter are considered respirable by humans Thus, for the purposes of Proposition 65, carbon black particles 10 m or less shall be considered respirable. Exposure to carbon black, per se, does not occur when it remains bound within a product matrix, such as rubber, ink or paint. You can find the notice on-line at and the latest Prop 65 list (February 21,) on-line at .

Californias Lead-Safe Schools Project. Over the past four years, the Labor Occupational Health Program at U.C. Berkeley has been funded by the California Department of Health Services (DHS) Childhood Lead Poisoning Prevention Branch to develop, implement and evaluate Californias Lead-Safe Schools Project. The Lead-Safe Schools Project provides information and training to school district maintenance departments on lead-safe work practices and setting up a lead management plan. The need for this project was determined through a study conducted by DHS which found that 96% of the states schools have lead in the paint and that maintenance workers were routinely performing tasks that expose school children and themselves to lead dust. To address this need, project staff developed a kit, modeled on EPAs Tools for Schools Kit, that includes an easy-to-understand guide for supervisors on how to implement a lead management plan, booklets in English and Spanish for workers, and a curriculum with an introductory videotape for teaching maintenance staff about lead-safe work practices.


Staff also created a six-hour training of trainers (ToT) program for training supervisors how to teach the curriculum to staff, a website, and a technical assistance hotline. Development of all materials and activities have been guided by an advisory board comprised of agency and school district representatives as well as the union representing school maintenance employees in California and state associations such as the California Association of School Business Officials (CASBO). The Lead-Safe Schools Project was also actively endorsed by then State Superintendent of Education in California, Delaine Easton. She wrote a cover letter to all elementary school districts about the program and appeared in the educational videotape.


The Lead-Safe Schools Guide and worker booklets have been sent to 881 school districts around California. As of January 31, project staff had provided 77 ToTs around the state, with a total attendance of 1279 participants, representing 416 California school districts. Attendees have been very enthusiastic about the ToTs which include numerous participatory activities such as small group activities, hands-on practice and review games.


Project staff have also conducted over 20 presentations at statewide, regional and national meetings of organizations serving school maintenance staff, including the California Association of School Business Officials, the Coalition for Adequate School Housing, and the California School Employees Association as well as the American Industrial Hygiene Association, the American Public Health Association, and EPA. There have been numerous hits on our website which includes copies of our materials as well as a section on frequently asked questions.


The project has been evaluated by an outside evaluator who found, using a quasi-experimental design, that twice as many districts in the intervention group had at least partially implemented a lead management plan than those in the control districts. Sixty-two percent of supervisors attending one of the projects ToTs returned to their district and trained employees. The evaluator also found substantial differences between the two groups in reports of most lead-safe work practices. Those from districts trained by the project were much more likely to report that their workers keep kids away from the work area, work wet, use plastic sheeting, clean the sheeting, and never throw paint chips in the trash. Project funding ends June 30, .

Agency Guidelines for Carcinogen Risk Assessment. In early March , EPA announced the availability of draft final Agency Guidelines for Carcinogen Risk Assessment for a 60-day public comment period. EPA also released for public comment draft supplemental guidance for assessing children's risk, entitled Supplemental Guidance for Assessing Cancer Susceptibility from Early-Life Exposure to Carcinogens. This draft supplemental guidance provides the proposed approach for assessing cancer risk resulting from early-life exposure to mutagenic environmental contaminants. When completed, the Cancer Guidelines (along with the supplementary guidance on children's risk) will set forth a revised set of principles and procedures to guide EPA scientists and risk assessors in assessing the cancer risks resulting from exposure to chemicals or other agents in the environment. They will also inform Agency decision makers and the public about these procedures. This draft supplemental guidance is new and will be peer reviewed by U.S. EPAs Science Advisory Board. Information is available on-line at:


Measures of Contaminants, Body Burdens, and Illnesses in Children. EPA recently released a report, America's Children and the Environment: Measures of Contaminants, Body Burdens, and Illnesses (Second Edition), showing presenting key measures of children's health and the environment that show trends and progress in protecting children's environmental health and show areas that need improvement. Information is available on-line at:


Clean Air Act Violations Settlement. The Department of Justice and the Environment Protection Agency finalized a settlement of the government's lawsuit against Toyota Motor Corporation for Clean Air Act violations involving 2.2 million vehicles manufactured between and. Under the settlement, Toyota will spend $20 million on a supplemental environmental project to retrofit up to 3,000 public diesel fleet vehicles to make them run cleaner and extend the emission control system warranty on affected vehicles. In addition, Toyota will accelerate its compliance with certain new emission control requirements, and pay a $500,000 civil penalty. The settlement will cost Toyota an estimated $34 million.


HQ Division Director moves on. Mary Smith, Director of the Indoor Environments Division for the past seven and a half years, has been appointed as the new Director of the Engineering and Analysis Division in the Office of Science and Technology in the Office of Water, effective February 1,.


Grants. On January 24, IED published and Request for Applications (RFA): "Indoor Air Quality: Communication, Education, and Outreach Programs: Announcement of Availability of Funds and Request for Applications," with applications due February 28. These grants are for national organizations only, as described in the document. Also, a new rule requires that our program, both nationally and in the regions, compete virtually all of the kinds of grants which our program provides, even the small ones which we usually award for IAQ in Region 9. This new situation has led to significant delays our awarding local grants since October 1,.


California Assembly Asthma Hearing, Feb. 19. Barbara Spark has been invited to speak on the IAQ Tools for Schools program during the Improving Air Quality panel at the February 19 California Assembly Committee hearing: Asthma: Why Californias Children Cant Breathe. The hearing is sponsored by the California Assembly Committee on Health, Chair Dario Frommer, California Assembly Committee on Environmental Safety and Toxic Materials, Chair John Laird, and California Assembly Select Committee on California Children's School Readiness and Health, Wilma Chan Chair. Information is posted at


Media. Barbara Spark was interviewed by KRON TV-4 San Francisco for a 9PM news segment for which viewers "vote" for the topic they want to see addressed. The topic on 10/30 was "Is Sick Building Syndrome Real?" Barbara discussed EPA's approach to SBS, as well the syndrome's recognition by other cognizant authorities. The segment ended with a display of a number of our guidance materials, including "IAQ Tools for Schools.


IAQ Tools for Schools

        M.O.U. with California Association of School Business Officials (CASBO). A USEPA/CASBO memorandum of understand formalizing our cooperative partnership to promote implementation of the IAQ Tools for Schools program has been signed by our Regional Administrator Wayne Nastri, and CASBO Executive Director Kevin Gordon.

        Fresno Unified School District. The project to implement the IAQ Tools for Schools (IAQ TfS) program at all schools in the Fresno Unified School District was officially launched at a large (130 person) training workshop on November 13, in Fresno. This project, led by Shelly Rosenblum, is notable not only for the fact that FUSD is the fourth largest district in California (and in an area with very high asthma rates), but that the this endeavor is a full partnership between the district, the Teachers Union (FTA), and EPA, with an signed MOU pledging that all parties will work cooperatively together to improve the indoor environment for students, teachers and staff. About one-half of the people attending the Nov. 13 event were teachers union site representatives, and the other half came from district operations administration or field work (HVAC techs, Enviro. H & S, etc.). Richard Shaugnessy and Shelly Rosenblum were the primary trainers. EPA Region 9 Air Division Director Jack Broadbent presented a Great Start award to the district Superintendent Dr. Santiago V. Wood and teachers union President Sherry Wood.

        Workshop for Asthma Coalitions - An all day workshop focusing on programmatic and marketing aspects of IAQ TfS was presented by Barbara Spark to representatives of asthma coalitions in eight counties at the annual meeting of the Central California Asthma Project, October 11,. In Shelly Rosenblums absence, Barbara was ably assisted by Sue Cox, Risk Manager of Visalia USD, and Adina Neale, IAQ Coordinator at Saugus USD. Also attending was David Nunez, MD, Chief of the California Asthma Public Health Initiative. Thanks in part to substantial grants from the California Endowment (CAFA grants), increasing numbers of asthma groups are addressing indoor (as well as outdoor) environmental issues related to asthma, including implementation of the IAQ Tools for Schools program.


RAMP/Schools - A retreat of the Advisory Committee of the Regional Asthma Management and Prevention Initiative (RAMP) (Barbara Spark is an Advisory Group member), identified asthma in schools as one of four areas of key concern for new hands-on work groups. On a parallel track, Shelly Rosenblum and Barbara Spark have met with a RAMP "schools" sub-committee" looking into the feasibility of an asthma-friendly schools initiative in the five SF Bay Area RAMP counties, with IAQ Tools for Schools as a first project.


Mold Miscellany:

        Roundtable. Barbara Spark gave a presentation on the evolution of EPAs (IEDs) program and policies related to mold at a West Coast meeting of the Environmental Policy Advisory Committee of the Real Estate Roundtable, Nov. 6, . (The roundtable describes itself as: the organization that brings together leaders of the nation's top public and privately-held real estate ownership, development, lending and management firms with the leaders of major national real estate trade associations to jointly address key national policy issues relating to real estate and the overall economy. A number of California real estate interests organizations participated. EPA Region 9 Administrator Wayne Nastri was the key speaker.

        ICMA Webcast. Barbara Spark gave the introduction, and hosted a national webcast on mold for the International City/County Management Association in October.

        Toxic Mold Litigation Conference. Barbara Spark spoke on EPAs mold guidance and program at a mold litigation conference provided by the American Conference Institute in San Francisco in October. Attendees primarily were defense attorneys and insurance companies. The luncheon speaker was the Judge in the $32M Ballard case in Texas.

Capitol Area East End Complex. Construction on Block 225 was completed last summer, and the building is now fully occupied. Indoor air quality tested occurred before occupancy and once after occupancy. The final IAQ testing at this building will occur in the near future. Blocks 171-174 are planned for occupancy in April. Air quality testing was conducted before furniture installation and will be conducted again shortly before occupancy. Block 225 has been awarded the Gold LEED rating. Blocks 171-174 anticipate a Silver LEED rating. The most recent quarterly report on the CAEEC to the Legislatures Joint Rules Committee can be found on-line at:


Article on California's Road to Sustainability. The USC Marshall School of Business Women's Leadership Board, a group of undergraduate students (both men and women), is developing a case study on the State's Road to Sustainability. The State and Consumer Services Agency, representatives from the Green Team, as well as numerous other state agencies involved with the Capitol Area East End Project were interviewed on February 3. Professor Suzanne Savary is organizing this case as well several of the students are working on the project. This is an opportunity to educate young people about organizational behavior and the process required to make major policy changes in state government. A report will be issued in the near future.


Environmentally Preferable Products (EPP) Database. In October, the California legislature passed Senate Bill 373, which included a provision charging the State Architect to develop and maintain on its Web site a database of environmentally preferable products (EPP) that are used in school construction and renovation. Given that identical products are used for both school and office building construction, the development of such a database of construction products is a tremendous opportunity to promote sustainable building materials throughout California. Leon Alevantis is a member of the advisory group for this project.


A draft Sustainable Procurement Charter has been prepared between DGS and CIWMB. This charter outlines a program to provide state agencies with information and assistance regarding environmentally preferable purchasing. It is a result of implementation of Assembly Bill 498 (Chan, Chapter 575, Statutes of), which requires the procurement of goods and services that have a reduced effect on human health and the environment in comparison to competing goods or services that serve the same purpose. Other agencies and departments are being encouraged to sign this Charter. The draft will be presented at the Undersecretarys meeting on 3/11/03.


Economic Analysis of Green Building. Under the direction of the Task Force and with funding from numerous state agencies, a draft report on green building economic analysis has been developed by the subcontractor retained for this purpose. The report seeks to determine how much green buildings cost, what financial benefits they provide, and whether or not green buildings are cost-effective over their lifetime. This report will help determine the level of state funding towards future sustainable state construction.


UC Merced Conference. Members of the Task Force will also participate and give presentations at the UC Merced Conference on sustainable building for higher education scheduled for April 28 and 29, .
