May Board Presentation on Ozone Generator Report. Staff presented its new test results on ozone generator performance to the Board at their May meeting. These devices are so-called air purifiers that purposely emit substantial amounts of ozone. Recent testing by ARB staff of four models of ozone generators showed all four models can produce room ozone concentrations above the one-hour state standard of 90 ppb and the FDA standard of 50 ppb for medical devices.

started with letters to local
Chairmans Briefing on Indoor Air and Formaldehyde ATCM. On July 25, we briefed our new chairman, Dr. Robert Sawyer from UCB, on indoor air quality, and Stationary Source Division staff briefed him on the Air Toxics Control Measure (ATCM) they are developing to limit emissions of formaldehyde from composite wood products. The briefing went well, and afforded staff an opportunity to update Dr. Sawyer on the findings of the AB 1173 report to the Legislature on indoor air, as well as on new information on the health effects of formaldehyde. The ATCM Board hearing has been postponed to January.
Underwriters Laboratories, Inc. Confirms Plans for Revising Ozone Emissions Test Protocols for Air Cleaners. Underwriters Laboratories project managers recently confirmed their schedule for revising the UL test protocol for ozone emissions from electrostatic air cleaners (Section 37 of UL Std. 867) and combining that standard with UL 507, which currently applies to other air cleaners. ARB staff are serving on ULs ad hoc (non-voting) committee for revising UL Std. 837. UL expects to forward the proposed minor changes to Std. 867 for review by the full committee by early August, and the proposal for the fully revised standards by the end of August. For the new combined standard, UL is planning to change from a chamber test method that includes measurement of room air concentrations to an emissions test protocol that measures emissions in the output stream and requires subsequent modeling to estimate the resulting room concentrations.

Indoor PM Health Effects Study. An ARB-funded study of the potential toxicity of particulate matter (PM) from indoor sources of PM began in April. UC Davis Professor Fumio Matsumura and colleagues will use in vitro human cell models to systematically investigate toxicities of indoor sources of PM, as well as associated vapor-phase components. UCD will evaluate the following indoor PM sources for toxicity: 1) cooking, 2) candle burning, 3) incense burning, 4) firewood burning, and 5) vacuuming. UCD will use human cell lines consisting of the two main target cell types for PM: macrophages and lung epithelial cells. This study is designed to develop methods and make a preliminary assessment of which indoor sources of PM are responsible for the greatest toxic impact. The resulting toxicity data should help guide future health effects studies, and help assess the health risk from indoor sources.
Johns Manville Formaldehyde-free Insulation. Representatives from Johns Manville (JM) briefed ARB staff in May on the status of production and sales of their formaldehyde-free insulation products. The company has put together an impressive array of low-emitting products that are enjoying some solid marketing success. Their formaldehyde-free residential insulation product, for example, is the exclusive choice of California Home Depots. The JM representatives indicated that the philosophy of their company changed after their historical asbestos problem: they now strive to develop products that are ahead of their time and as environmentally safe as possible.
Final Report 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 final report that explored this topic, Indoor Air Chemistry: Cleaning Agents, Ozone and Toxic Air Contaminants, by Dr. Bill Nazaroff of UC Berkeley, has been completed and released. Findings indicate ethylene-based glycol ethers, a toxic air contaminant, were present in 6 of the 21 products tested, at levels ranging from 0.8% to 9.6% by weight. Twelve of the products tested contained ozone-reactive compounds at levels ranging from 0.2% to 26% by weight. When cleaning products were used in the presence of ozone, investigators observed a high degree of reactive chemistry. 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. An individuals proximity to these pollutants and 2-butoxyethanol in some cleaning products may lead to unhealthful exposures. The report is available for download at on-line:

Asthma Strategic Plan
The California Breathing Program (CB) implements asthma awareness programs in several target populations across the state via the Disparities Mini-Grantee Program. Several of the and mini-grantees have focused on educating different audiences on the link between indoor air quality and asthma exacerbation.
Lung Association of
Clinica de La Raza
Mid-City Community Advocacy Network San Diego, CA: Educated asthma advocates who targeted East African, Southeast Asian, and Latino populations on indoor air quality and healthier housing and clean neighborhoods by holding local education forums and community meetings. This program led to the formation of the successful Healthy Homes project.
Articulate key issues related to asthma and housing
Highlight solutions and strategies from other regions
Begin a dialog among housing inspectors, code enforcers, asthma experts, and possibly CA apartment owners, insurance companies, and community members.
Determine next steps for action by
identifying gaps and discussing strategies for
In order to reach the above goals, the CAP Steering
Committee decided to conduct two housing and asthma meetings in
1st Meeting: Invite
counties/cities/coalitions already working on housing and asthma (teams of
housing inspectors, asthma experts, tenants, etc). At this meeting, we
will share with each other innovative practices and determine common themes.
Potential teams include:
2nd Meeting: Conduct a train the trainer strategy session (building on strategies identified in meeting #1) on how to implement asthma and home inspector programs with other counties/cities/coalitions interested in developing asthma home inspector programs.
If anyone from the Interagency Working Group on Indoor Air Quality would be interested in participating or could tell us about local housing and asthma efforts.
Maternal, Child and Adolescent Health (MCAH) Action,
the organization of
Collaborative for High Performance Schools (CHPS). The CHPS Technical Committee is in the process of revising the Best Practices Manual Volume III (Criteria), and it has issued several beta versions for public comment. DHS-IAQ staff sit on several sub-committees, as well as chair the IEQ sub-committee. The comment period for the 3rd Public Review draft extends to August 18th.
IEQ subcommittee: The IEQ subcommittee completed its first review for the December draft revision, as well as provided responses to public comments and made follow-up changes through July. The key changes in the forthcoming revision include:
o New credit for increased ventilation effectiveness through thermal displacement ventilation;
o Revise credits for Low-emitting Material Selection. It will now employ an expanded list of materials including cabinetry, teacher pupil desks and chairs and composite wood products;
o Require a 14-day flush-out (i.e., 24/7 maximum outdoor air) for all new construction and modernization projects, plus 4-day following touch-up work
o Clarify several HVAC design issues (conformity to Title 24; air intake requirements; provisions for natural ventilation), and source control measures.
The CHPS Policy subcommittee refined the credit for district resolution and provided clarification on what the scope needs to be for a resolution to qualify for the point. In the forthcoming revision, a district must pass a board-level resolution to mandate all new construction projects meet or exceed the CHPS qualifying threshold; all school additions (classrooms and other instructional areas) must incorporate appropriate CHPS best practices; and all modernization projects (i.e. projects that affect the building system-envelope, mechanical system and electrical system) must meet or exceed the CHPS qualifying threshold.
Green Action Team (GAT) Schools Workgroup. Schools work group is working on a School Tour event to showcase successful schools that have used CHPS Best Management Practices and to encourage other schools to take similar actions. The workgroup has drafted an invite list that includes the Governor and other high profile representatives. The team has selected three schools for the tour. Communications director Ken Hunt,Green Team Communications, California Department of General Services is working with the group to develop media and talking points for the event.
Schools Roundtable. Toni Stein and Deborah Moore (Green Schools Initiative )
have been actively organizing a Schools Roundtable focused on improving health
and safety in
o Outreach materials on Health and Safety issues. The goal is to educate stakeholders on how to achieve good Health and Safety conditions in existing and new schools including good IAQ and reducing asthma triggers. These efforts include identifying and evaluating EXISTING outreach materials that are being used throughout CA by different agencies, non-profits, school officials, and other stakeholders through a survey. This work is intended to assess the effectiveness and find gaps and to identify target audiences for outreach. The survey results will be used to establish a new strategy to generate a wave of outreach and improvements in existing and new schools
o Identifying, improving, repairing and
preventing, health and safety issues in schools. The goal is to help identify H&S
problems in schools. This includes
assisting in the development and promotion of a statewide school inspection
checklist and companion guidance document for identifying and making needed
repairs in schools. Such a tool is
envisioned to help standardize and make the process easy. Presently, the State has an Interim Evaluation Instrument used for
school assessments in allocating state repair funds. The work aims to expand upon the IEI and
offer an easy-to-use checklist for Statewide use. This will also be used to identify particular
conditions that cause poor IAQ, asthma triggers, and other health or safety
problems for assessment of "good repair" of
Green Schools Symposium. On
GAT EPP Workgroup. Because the state is engaged in many new construction and modernization projects and is committed to building LEED silver projects, we suggested that it would be very beneficial for the workgroup to seek out and contact the state bodies involved in purchasing of these materials and coordinate a strategy to provide them with standard EPP guidance to aid in selection of green building materials such as composite wood. Some of the constraints of doing this were discussed. Despite these, Rita Hamilton, DGS-PD was supportive and open to exploring the suggestion.
The EPP Best
Practices Manual was posted on-line on
Additionally the CA Gold Carpet Standard also was posted on DGS GAT website, and a DGS Management Memo was put in place to implement use of the standard.
o VOC limits: The new specification moved from specifying VOC category sums (i.e. aldehydes, aliphatics, etc.) to limits on each of the individual VOCs identified and quantified by testing. The specification specifies not-to-exceed concentrations for all of the air contaminants with health-based exposure limits. The limit for formaldehyde was reduced from 25 ug/m3 down to 16.5 (1/2 the crel). Additionally no first year allowance to not meet the formaldehyde limit was included. Additionally the new specification incorporated a provision to meet the LEED VOC requirements to assure harmony.
o Emission Test Protocols: The specification moved away from requiring full workstation emission testing in the large chamber according to an EPA RTI ETV test protocol to the option to test the primary workstation components (work surface, panels, and storage units) in small or medium chambers using the CDHS standard practice, or the BIFMA FES M7 standard test.
o Ventilation Rate: The IAQ specification was updated to incorporate the most recent Title 24 room ventilation rate parameters from the values for concentration calculations for meeting the limits.
o Component disclosure: The IAQ specification required all bidders to disclose the materials and processes used in the offered product line. This was not required in.
o Data submission requirements: In all bidder were required to report the identified chemicals of concern, the bid requires bidders to provide proof that they comply with the LEED requirements and only the awardee to provide compliance proof for the individual VOCs.
o Laboratory reporting: Companion to the specification a standardized automated electronic worksheet was distributed and required for reporting. The worksheets required input of laboratory measured chamber emissions and automatically calculated the resulting room concentrations for comparison to the cRELs.
After the initial bid was released, bidder questions were received by DGS; CDHS responded to ten IAQ questions. Clarification was provided to explain that the specification gives bidders flexibility to use a variety of testing options. It was clarified that any of the following testing protocols were acceptable testing methods for obtaining the US GBC LEED criteria: BIFMA M7.1 test protocol, California DHS Standard Practice, Environmental Technology Verification Test Protocol, Greenguard testing, or Indoor Advantage testing. Furthermore, it was clarified that Greenguard testing could be used as an option to show compliance to the California VOC acceptance criteria. Clarification was made to documents showing that the offered workstations are certified as meeting EQ Credit 4.5 Low-Emitting Materials, Systems Furniture and Seating under US GBC LEED CI were required at the time of bid submittal. The acceptance criteria and quality assurance provisions were amended to delete pre-delivery airing-out. The bid due date has been extended several times, and currently the due date is August 16th.
To begin developing a roadmap for harmonizing the development, testing and certification of green building products
o A collective vision of what harmonization will look like in 5 years
o Articulation of the critical issues/questions that stakeholders must pursue to achieve that vision
o Identification of the specific steps that stakeholders will take to pursue these issues
A presentation on related
CRI Adhesives Test Program. Toni and Jed met with Frank Hurd (CRI) to discus issues surrounding the CRI Adhesives Testing Program relative to the current California 01350 Standard Practice. Evaluation of their program for conformity to our Standard was started and indicates that their test program uses the same maximum allowable exposure limits as the CA 01350. However, further evaluation has been continued until September when their programs detailed test protocol will be reviewed and evaluated for further discussion. CRI has agreed to compile and send their test protocol documentation prior. This work complements DHSs efforts on wet products testing, i.e.,. defining a test protocol tailored to wet products addressing both long term emissions as well as short term (drying off period) emissions.
BIFMA Sustainability Standard. Toni is on the Ecosystems and Human Health Subcommittee and helping to develop a Target list specific to the Furniture industry, and issues of verification for their low-emission credits. BIFMA will be transitioning this standard development to NSF, and balloting may occur around April.
Harmonization with Greenguard Environmental Institute. Greengaurd has asked CDHS, CARB, and OEHHA to consider adopting an MOU to establish equivalency of GEIs Standard for Children & Schools certification to the CDHS standard practice used for the CHPS criteria.
Technical Assistance to ARB on Composite Wood Rulemaking. DHS-IAQ is providing guidance and technical support to ARB related to formaldehyde emissions testing of composite wood products. ARB staff from its Stationary Source Division (Jim Aguila and Lyn Baker) and Monitoring Lab Division (Mike Poore and Russell Grace) and the Enforcement Division (Chuck Beddow, Elizabeth Miller, R.C. Smith, and John Oback) visited the DHS-IAQ laboratory to view our large chamber and laboratory facilities.
DHS IAQ website. We recently updated our web pages on Indoor Mold with links to the latest guidance. In addition, we posted a Spanish translation of the current version Mold in My Home: What Do I Do? (in Spanish: Moho en mi casa: que hago?). See
Janitorial Products. The State of
Building Security. Rich Sextro of LBNL visited the CDHS Richmond Campus to demonstrate LBNLs Building Vulnerability Assessment & Mitigation Program (BVAMP). The tool is very useful for preparation for shelter in place.
Pilot Study on Cleaning
Product Exposures Associated with Asthma in Health Care Settings. We
are collaborating with the Occupational Health Branch (Jennifer Flattery) on a
pilot study to characterize exposures in health care settings from selected
janitorial products containing chemicals associated with asthma. We plan to partner with several large health
care facilities to conduct a 3-month pilot project to measure general
cleaning/janitorial product exposures associated with asthma. The purpose of
the project is to better understand chemical exposures in the workplace so that
prevention strategies can be developed. Also helping on the project is Weldon
Hall (chemist) and XimenaVeraga (IH).
Tire Derived Flooring Study.
Laboratory analyses for all materials tested have finally been completed. The schedule is that our Final Report (draft)
will be updated and sent in mid-August for review by the projects Advisory
Group. Then the report will go out for
public review in October. We anticipate
finalizing the report by December.

Smoke-free Multi-unit Housing. A campaign to move forward the issue of smoke-free multi-unit housing was initiated in September,. Representatives of TCS-funded agencies who are working in this area met for a one-day meeting to develop objectives and activities. The workplans goal is to get ten communities to adopt laws that would require new and existing multi-unit rental housing to designate a percent of units as non-smoking by . The provisions would include smoke-free indoor and outdoor common areas, balconies and/or patios, landlord disclosure, and declaring secondhand smoke a nuisance. Workplan activities include the development and/or modification of fact sheets, brochures and power point presentations for tenants and owners/managers, radio/tv, and print ads for the general population and apartment industry professionals, tool kit, model smoke-free multi-unit housing ordinance, incentives for developers to adopt smoke-free housing through insurance, taxes, etc., establish relationships with state housing agencies, and evaluation/surveillance activities which would include adding questions to the California Adult Tobacco Survey and conduct interviews and surveys of tenants, landlords and owners to assess their support for smoke-free multi-unit housing, and to conduct research to assess the economic impact of smoke-free multi-unit housing.

Virtual Asthma Network launched. EPA and the Robert Wood Johnson Foundation/Allies Against Asthma project have launched a new virtual network, "Communities in Action for Asthma-Friendly Environments" The network seeks to mobilize 1,000 communities by to lead the nation in quality asthma care. It is designed for community-based asthma programs and organizations that support them, including representatives of health plans and providers, government health and environmental agencies, nonprofits, coalitions, schools, employers, universities, and more.
As a partner in this Network, community-based programs have access to cutting edge tools and resources that may accelerate a program's impacts, drive conversations with successful asthma programs from across
the country, and improve health and financial outcomes. Network partners also have access to effective strategies which are Key Drivers for achieving positive health outcomes. While posting is limited to partners, anyone can access the information on the site.
The Region 9 Indoor Environments Team encourages colleagues to help spread the word about this important new resource, and can provide a forwardable e-mail announcement.

IAQ Tools for Schools / Environmental
Education. Shelly Rosenblum attended a meeting of the
EPA Environmental Education Workgroup in
IAQ Tools for Schools Curriculum. For the past several years, Shelly Rosenblum
has been working with the Earthteam
Environmental Network ,
an association of Bay Area science teachers and environmentalists who share
information on how to teach environmental science in a way which fully engages
and excites their students. Shelly has
expanded their view of the environment to include the indoor environment - especially the school indoor environment.
On the Saturdays, August 19th & 26th, Shelly attended training sessions for teachers
sponsored by the Earthteam. The training focused on creating videos using Mac
software, with the aim being to assist students in creating their own
environmental videos. Part of the
training was conducted by staff from KQED.
Shelly gave a short discussion of Tools for Schools and described the
video he would like students to make about the indoor environment - essentially
to take the material from the Region 9 "comic book" and turn it into
a video using real school footage.
