New Staff.  Ms. Stephanie Parent joined the Indoor Exposure Assessment Section on June 16,.  Stephanie has a Masters degree in Environmental Science and Policy from Clark University, and a BS in Environmental Policy Analysis and Planning from UC Davis.  She is working on several projects including updating some of ARBs indoor air quality fact sheets and guidelines, reviewing literature on indoor concentrations and sources of acrolein, and conducting outreach related to the air cleaner regulation.


Presentations at the ISEE - ISEA JOINT Conference.  ARB Research Division staff presented results from several in-house projects at the joint annual conference of the International Society for Environmental Epidemiology (ISEE) and the International Society of Exposure Analysis (ISEA), held in Pasadena in October. One presentation (by Tom Phillips) showed our current estimates of health and productivity impacts of indoor air pollution, updated from our estimates presented in the AB 1173 Report to the Legislature on Indoor Air Pollution in California. The current estimate of indoor air pollution costs in California is $71 billion annually. Another presentation (by Peggy Jenkins) discussed formaldehyde concentrations in California residences. These concentrations have shown a downward trend over several decades but have decreased little over the past 10 years, leaving levels in homes well above health benchmark levels. A third presentation (by Ryan Johnson) discussed a recent study of VOC concentrations in 24 new California homes, garages, and vehicles; results showed that several of the homes exceeded California health benchmarks for cancer and/or developmental toxicity for at least one VOC. Finally, Dane Westerdahl organized and conducted a half-day workshop on methods for fine and ultrafine PM measurement, which emphasized the importance of understanding the capabilities and limitations of standard instruments used for measuring PM.



Regulation Paper Presented at INDOOR AIR in Copenhagen.  At the conference of the International Society of Indoor Air Quality and Climate, Peggy Jenkins presented a paper on the necessity of regulation of some indoor sources to protect citizens from involuntary, high risk exposures indoors. The presentation reviewed the history of the perspective on regulation of indoor air, from the early days in which indoor air was viewed as a private good to recent years when indoor air has been recognized as a public good. In California, landmark regulations were recently adopted for two sources that provide examples of the situations for which regulation is a necessary, appropriate solution. In , the California Air Resources Board (ARB) adopted two new regulations: formaldehyde emission limits for composite wood products, and a regulation limiting ozone emissions from indoor air cleaning devices used in occupied settings. The composite wood products regulation was necessary because an industry that had previously self-regulated its formaldehyde emissions was hampered from further self-regulation in part due to competition from foreign manufacturers who could produce similar, but higher formaldehyde, products at lower cost. Here, government regulation was needed to create a level playing field for all manufacturers. The indoor air cleaner regulation evolved from a different situation, where a faction of the industry remains in denial of the adverse health impacts of ozone, and continues to market their products through misleading advertising.  Such actions leave government no choice but to adopt a clear regulation that prevents such abuse. These regulations will reduce the risk from two serious indoor air quality problems for Californians. Adoption of similar regulations at the national and international levels would provide more effective protection for all. 


Indoor Air Cleaner Regulation.   This regulation, which limits ozone emissions from portable air cleaning devices and requires electrical safety testing, became final on October 18, (see    Manufacturers, distributors, and retailers are required to be in full compliance with notification, testing, certification, labeling, and sales requirements by October 18,.  Underwriters Laboratory, Inc. (UL) and Air Quality Sciences (AQS) have joined together to provide testing services for Section 37 (the ozone emissions test) of UL Standard 867, and successfully completed ARBs audit process in late.  Intertek (ETL) is expected to have their test chamber ready in Spring,.  The certification application form and instructions have been made available on ARBs website at , and a set of Frequently Asked Questions has been posted at .


New Home Ventilation and Indoor Air Study. The New Home Study draft final report was reviewed and approved, with comments that need to be addressed, in March, by the Research Screening Committee (RSC) meeting.  The final report is undergoing revision by the Principal Investigator (PI), Bud Offermann, to address the RSCs comments.  Delivery has been delayed, but a final report is expected to be available in late spring, .  The PI presented findings from the study at an ARB Chairmans Seminar and at a meeting of CEC staff (see slides at   The key study results are that formaldehyde concentration levels are too high and air exchange rates (AER) are too low in new California homes.  Results showed that 59% of the homes had 24-hour indoor formaldehyde levels above OEHHAs 8-hour Indoor Reference Exposure Level (REL) of 27 ppb for acute irritant effects.  All of the homes had indoor formaldehyde levels that exceeded the Proposition 65 guidelines for cancer and developmental effects, and the chronic REL of 2 ppb.  Indoor levels of acetaldehyde and a few VOCs also exceeded health-based guidelines.  Based on tracer gas measurement results, two-thirds of the homes did not meet current ventilation guidelines.  The CEC staff used the results of this study to help develop their new energy efficiency standard that requires mechanical ventilation in new homes (see below). 


Composite Wood Formaldehyde Regulation.  The composite wood product regulation, which established two phases of increasingly stringent formaldehyde emission limits for composite wood products (hardwood plywood, particleboard, and medium density fiberboard), became effective on April 18, .  The compliance date for most of the Phase I standards was January 1,.  Phase II compliance dates for the different types of composite wood materials vary from January to January .  Presently, over 250 mills have been certified to manufacture ARB compliant composite wood products worldwide.  ARB staff continues to work with industry, test organizations, and others to finalize test methods, approve third party certifiers for mill certifications, promote the availability of ultra-low formaldehyde emitting products and to facilitate the availability of certified products.


Green Buildings. Staff met with the State Building Standards Commission (BSC) and Department of Housing and Community Development (HCD) staff regarding various drafts of the Green Building Standards Code (GBSC) and offered a number of measures for inclusion in the standards.  Some measures were included in the new GBSC approved by BSC in July, but others remain to be incorporated.  ARB plans to work with BSC and HCD to refine and update the measures currently in the GBSC and to include new measures targeted toward reducing greenhouse gases.  Indoor Program staff also have been actively involved in other green building programs, including the revisions to Build It Greens ratings related to indoor air quality in new single family homes, and the revisions to the CHPS criteria for school construction and renovation and for new portable and modular classrooms. 

Comments on State Building Energy Efficiency Standards. Staff submitted comments on the draft Building Energy Efficiency Standards that were proposed by the California Energy Commission. These design standards represent a major change because they will require new homes to have an outdoor air supply via a whole house mechanical ventilation system.  Several other states and nations have required this for some time.  Recent studies funded by the ARB and the Commission, and some previous studies, confirmed that mechanical ventilation is needed in new homes because so many of them have insufficient outdoor air exchange and very high formaldehyde levels.  For the residential building standards, staff recommended improvements for the testing, inspection, and maintenance of mechanical ventilation systems, and for air filtration.  Staff comments on the nonresidential building standards focused on the need to improve air filtration, ventilation control systems that use CO2 sensors, and testing of ventilation systems. The approved standards will become effective in. 


In-Vehicle Study of New Cars.   During summer, , we conducted a pilot study of emissions from materials inside vehicles in a small number of new cars borrowed from ARB employees.  This in-house study measured CO2 (primary source is exhaled breath of vehicle occupants), volatile organic compounds (VOCs), and ozone.  In several of the vehicles, CO2 levels rapidly exceeded 5000 ppm, the Cal/OSHA Personal Exposure Limit (PEL), in 8 of 11 cars, after periods of driving with windows and vents closed.  The maximum value measured was 8163 ppm.  Levels rapidly decreased when a vent was again opened.  While the levels measured do not pose a health risk from commutes of average duration, periodic opening of vents during longer drives may help prevent excessively high CO2 levels and the possibility of drowsiness.  VOC results are still undergoing analysis.  In early, semi-volatile compounds (SVOCs) such as phthalates and PBDEs (fire retardants) will be measured using wipes to sample from dashboards and the inside of windshields. 


Small and Medium Commercial Building Study.  The survey and field study of IAQ and ventilation in small and medium commercial buildings (under 4 stories and less than 50,000 square feet) are both well underway by investigators from UC Berkeley, LBNL, and UC Davis.  A wide array of measurements of ventilation, indoor air quality, and comfort factors will be obtained in 40 buildings.  The data will be used to examine the relationships among indoor air quality, ventilation, and building characteristics.  Results will be used by the Energy Commission to update their Title 24 energy efficiency standards in, and by ARB to assess the need for source emission limits or other actions to reduce exposures to indoor contaminants. 


Quantifying Pollutant Emissions from Office Equipment. Investigators from UC Berkeley and LBNL have completed measurements for a study of the relationship between energy consumption and emissions for PCs and printers.  The investigators also are examining the primary temporal and operational factors that influence emissions from this equipment, and identify mitigation measures that operators can take to reduce emissions and exposures from PCs and printers.  The slides from the Chairmans seminar presented by the PI, Dr. Tom McKone, in early January, are available at and provide the preliminary results.  The final report is expected to be available in summer,.   


Revisions to EPAs Energy Star Program.  Staff discussed EPA's revised Energy Star-IAQ Package program requirements with EPAs leadperson for the Program and relevant Region 9 staff, and submitted written comments to press for stronger IAQ Package requirements, especially for low emitting building materials.  The IAQ Package is a set of provisions that builders of Energy Star homes can use to assure healthier indoor air quality.  EPA has conducted a few pilot programs for the IAQ Program, but the provisions remain more focused on eastern problems such as radon, and do not include, for example, ARBs recent limits on formaldehyde emissions from composite wood materials. We encouraged EPA to adapt the IAQ Package for California builders to better reflect California's (more protective) regulations and guidelines.  We recommended that the IAQ Package require compliance with ARBs new Air Toxic Control Measure for Composite Wood Products, rather than just meeting ANSI and HUD standards, which are very weak.  There are already materials on the market that meet ARBs new regulation, and more are expected to become available in the coming months.  EPA also was urged to include a requirement for insulation materials with no added formaldehyde; there are products readily available that can meet all residential needs, and in California, they are marketed at little or no added cost for the home market.  EPA made some changes in response to our comments, and has indicated that they will consider others in the future.    


Review of Federal Guidance Draft on Preventing Environmental Health Problems in Manufactured Homes, Schools and Offices.  On October 17, , ARB staff participated in a meeting convened by the Centers for Disease Control (CDC) in Washington, D.C. to discuss their preliminary draft document on Keeping Safe and Healthy in Manufactured Structures. The purpose of the document is to provide non-regulatory guidance to occupants who live, work, study and play in manufactured buildings, as well as to industry organizations, health and environmental professionals, government agencies, and others involved in the design, manufacture, purchase, installation, regulation, operation and maintenance of manufactured buildings. CDCs purpose in convening the meeting was to obtain input from experts and key stakeholders on an early draft of their guidance document. The impetus for the meeting was the problems experienced with manufactured trailers and homes used for Hurricane Katrina victims, including elevated formaldehyde levels, mold issues, pest issues, inadequate ventilation, and others. CDC plans to revise the document based on the comments and information received, and release the revised version early next spring for public review.  


Health Canada Moving Forward on Indoor Air. Indoor Exposure Assessment Section staff met with staff of Health Canadas Water, Air and Climate Change Bureau via conference call at Health Canadas request to share information on our respective indoor air quality programs.  Health Canada is launching a 4-year program to assess the risks posed to Canadians by indoor air contaminants.  They plan to identify a priority list of substances for which assessments will be conducted and guidelines and regulations developed.  Accordingly, the Canadians were especially interested in our authority over indoor air and how we fund our activities.  They also are engaged in a number of indoor air quality studies, some of which may provide very useful information for ARB as well (see   Both parties learned much from the exchange, and we agreed to talk again every six months or so. 


Scientific Review Panel Approves Noncancer RELs.  At their December 5, meeting, the Scientific Review Panel approved OEHHAs recommendations for proposed Reference Exposure Levels (RELs) for acetaldehyde, acrolein, arsenic, formaldehyde, manganese, and mercury.  The RELs provide health protective guidance levels for acute, 8-hour, and chronic exposures to chemicals that have non-cancer health impacts.  Reference exposure levels are concentrations of a chemical at or below which adverse non-cancer health effects are not anticipated to occur for a specified exposure duration.  Although developed for the purpose of meeting outdoor Air Toxics Hot Spots Program needs, OEHHAs RELs provide good guidance for health-protective indoor concentrations of air pollutants in non-occupational indoor settings for the stated exposure times. 

For more information on the SRPs actions, see   For information on the new RELS, see .



Wildfire Smoke Guide

Staff assisted with updating a guide to help local officials cope with smoke from wildfires. Various ARB staff worked with staff from the Department of Public Health, the lead agency, as well as Cal/OSHA and other agencies.  A major improvement to the guideline included a policy regarding the operation and management of ventilation systems in commercial and public buildings to protect workers during periods of especially high PM levels.  Other noteworthy additions include an extended section on respiratory masks (e.g., N95s, P100s), improved discussion of home air cleaning options, and sample public advisories from local communities. For further information see the revised guideline and Appendix A at ).

New Asthma Report and Strategic PlanThe Strategic Plan for Asthma in California, 20082012 (SPAC) was released in April.  Five major Goals are identified in the SPAC: Implementation, Monitoring and Evaluation; Surveillance and Research; Health Care; Indoor Environments, and; Outdoor Environments. Recommendations in the Plan are intended to mobilize individuals, organizations, communities, and state and local agencies to collectively take clearly defined, comprehensive, and coordinated action on asthma over the next five years.  To learn more about asthma in California, see The Burden of Asthma in California: A Surveillance Report 


California Breathing (CB) Grants and Awards  

CB completed its Mini-Grants Program to address asthma disparities, with several grantees working on IAQ issues:

         San Francisco Dept. of Environment - Analysis of asthmagens in cleaning products found in stores near a housing development in Bayview Hunters Point area. Trained community health workers to interview residents, provide alternative cleaning products, and then conducted another interview to evaluate changes.

         EarthTeam - Reached over 500 students in Richmond and Oakland with the curriculum  Somethings in the Air

         INMED/Mothernet Conducted home assessments as part of case management for 25 African American children in Los Angeles


(NEW!) In, CB also initiated a second grant program, Strategic Plan Implementation Grants (SPIG), with higher funding amounts, aimed at a broader audience and intended to further implementation of the CA Strategic Plan for Asthma in California.  Focus areas for include housing, outdoor environments and community engagement in local planning and policy. In the funding cycle three grant projects are focused on IAQ issues in homes:

         Californians for Pesticide Reform Working with partner organization Physicians for Social Responsibility/LA on implementation of Integrated Pest Management strategies in MUH. Using a combination of tenant education, organizing negotiation with managers of non-profit housing developments.

         Sonoma County Asthma Coalition Multi-pronged approach to address mold and moisture intrusion through code enforcement strategies, especially with regard to home-based problems. Using existing relationships with building departments and others in the county the Coalition is conducting trainings and enhancing web-based information for code enforcers on healthy homes principles and strategies for dealing with mold in homes.

         Shasta County Tobacco Control Program Working with senior mobile home parks to implement SHS policies


(NEW!)  California Breathing has launched a new recognition program called AIR Health (Achievements in Respiratory Health), that is being piloted in San Francisco Bay Area elementary schools. The AIR Health Awards recognize schools that are working to create healthy environments for children and school personnel and challenge schools that have not yet addressed key environmental issues to get started. Schools that qualify must meet a list of criteria that are focused on reducing common air pollutants and other contaminants that exist in the school environment, both inside buildings and in adjacent outdoor spaces. By addressing these criteria, schools create a healthier atmosphere for learning, not just for staff and students with asthma, but for everyone at the school site.  Based on the number of criteria achieved, schools will receive both an plaque and a monetary stipend.  After evaluation of the pilot, we hope to broaden eligibility to schools statewide.


Healthy Homes & Schools. 

        CB staff hosted an Essentials for Healthy Homes Practitioners Course in Richmond on May 20-21. The two-day training was co-sponsored with the CLPPB and LA County Environmental Healths Healthy Homes Program (DPH). Curriculum developed by Natl. Center for Healthy Housing. 40 participants included code enforcers, health workers, environmental health specialists, housing advocates.  

        CB has also convened two meetings of an Intra-Divisional DEODC Work Group on healthy housing, which includes representatives from IAQ (Environmental Health Labs), California Breathing Asthma Program (Env. Health Investigations Branch), Childhood Lead Poisoning Prevention Branch (CLPPB), Occ Health (OHB) and  the Environmental Exposures Section (EHIB.)  The group is looking into possible collaboration on healthy homes issues.

        CB staff provided a presentation on Healthy Homes and Asthma at Cal Environmental Health Association symposium in March and APHA in Oct.  

        CDPHs Tobacco Control Program put on a 3-day conference on Second-Hand Smoke in December. Half the conference was devoted entirely to SHS and Multi-Unit Housing. (Cal Breathing was on planning committee)

        With the SF Asthma Task Force, and the Green Purchasing Institute, CB held a kick-off meeting in SF on developing a pilot project to promote less toxic products and safer cleaning practices in childcare centers.

Composite Wood.  California Air Resource Board (CARB) funded CDPH-IAQ under an Interagency Agreement for technical assistance in development and evaluation of methods to be used in the enforcement of their Composite Wood Airborne Toxic Control Measure (ATCM 93120) regulation.  The project includes several sub-tasks which continue through June (and possible longer).  The project tasks include:


Evaluation of a field protocol for formaldehyde emission testing of composite wood.  To facilitate the enforcement of this regulation, CDPH-IAQ staff developed a field protocol for use of the Field and Laboratory Emission Cell (FLEC) emissions chamber and a real-time formaldehyde monitor (INTERSCAN 4000 formaldehyde analyzer). The performance of the field set was evaluated for its precision and correlation with ASTM (D 6007) and ISO (16000-10) small chamber test methods over a range in temperature and relative humidity.  Sampling conditions, e.g., sampling air flow rate and equilibration time and the wood product properties were examined for their effects on the performance of the field set.  We compared the averaged response of the INTERSCAN monitor to time-integrated cartridge (DNPH) measurements.  In the formaldehyde range of 50~300 μg/m3, measurements of these two methods correlated well (r2~0.97) with a 10% bias (Interscan lower than DNPH) in this concentration range.  We also found that sampling from small chamber was equivalent to that of FLEC method, although the FLEC/INTERSCAN underestimated formaldehyde levels compared to the small chamber/DNPH set.


Establishment of equivalence between large and small chamber tests.  CDPH-IAQ staff conducted large chamber and small chamber emission tests on composite wood samples provide by ARB staff.  The wood samples included panels made of industrial hardwood plywood (HWPW), industrial particleboard (PB), and medium density fiberboard (MDF).  ARB staff cut the panels into 4x4 and 5x5 pieces and developed them to the CDPH Lab prior to each test.  Emission tests were conducted in CDPHs large and small chambers, following ASTM E 1333 and D 6007 methods, respectively.  For small chamber tests, the ATCM 93120 requires testing nine specimens per sample in groups of three pieces per chamberParallel small chamber tests were conducted in the ARB test facility.  Formaldehyde concentrations were determined using DNPH cartridges and HPLC-UV analysis, and corrected for temperature and relative humidity per ASTM methods.  In each large chamber test, duplicate DNPH samples were collected.   Sample concentrations fell into the three different ranges defined under ATCM (as measured by the large chamber method).


Comparison of laminated board to raw board emissions is the next task that is beginning in early.

Report Supports Improved Workplace Standard Setting for Cancer and Reproductive Hazards.  Many California environmental regulations are based on scientific risk assessments performed by the Cal/EPA Office of Environmental Health Hazard Assessment (OEHHA). OHB commissioned OEHHA to assess the feasibility of using the same scientific methods to develop recommendations for health-protective exposure limits in the workplace. The project focused on evaluating chemicals known to cause cancer or reproductive harm (i.e., chemicals on Californias Proposition 65 list). The report shows that health-protective exposure limits for workers can be calculated based on existing OEHHA risk assessments. This information will assist OHB in recommending priorities for Cal/OSHA rulemaking and promoting an improved methodology for health-based PELs.  The reports Executive Summary is available on-line at:

California Safe Cosmetics Program Releases Chemical Lists.  The California Safe Cosmetics Act of requires cosmetics companies to report products that contain chemicals known or suspected to cause cancer, birth defects, or reproductive harm. This information will be reported to the California Department of Public Health. To assist companies with reporting, the California Safe Cosmetics Program in the California Department of Public Health has compiled a list of these chemicals using reports and lists from authoritative bodies. The list is now available online in English, Spanish and Vietnamese. The cosmetics online ingredients database system is under development. Please note: the system is not yet ready for manufacturers to submit chemical information. For more information, visit .


 Asthma Update: OHB Activities and Publications. 

        Revised Consensus Standard for Safer Cleaning Products. OHBs Work-Related Asthma Prevention Program submitted comments and vote on revision of GS-37, the Green Seal standard on institutional cleaners. CDPHs Indoor Air Quality section was also involved. This new version of GS-37 has stronger health and environmental protections including a prohibition of ingredients known to cause allergic-type asthma, strengthened toxicity and corrosivity limits, tighter limits on ingredients that can cause indoor air pollution, and strengthened limits on chemicals that can be absorbed through the skin. Employers should purchase products using guidelines such as GS-37. See information posted at

Name Change.  The Tobacco Control Section has begun to take steps to become a Branch in the California Department of Public Health.  One of the first steps is a name change; we are now called the California Tobacco Control Program (CTCP).


Secondhand Smoke in Cars.  CTCP was awarded a NPHIC Gold Award (National Public Health Information Council) for its Smoke-free Cars with Minors Law implementation educational campaign.  To see portions of the award winning campaign go to and click on 'smoke-free cars'.


Smoke-Free California: Celebrating our Success and Envisioning our Future.  The CTCP Secondhand Smoke (SHS) and Multi-Unit Housing (MUH) Workgroups collaborated this year to host a statewide conference that addressed limiting exposure to SHS throughout California.  The December conference was a huge success with over 230 attendees, including some of our national partners.  Many participants stated that this was "one of the best conferences they had ever attended".  The conference link is:


Secondhand Smoke Workgroup.  The workgroup continues to meet bi-monthly to assist in the development and implementation of strategies to increase the number of voluntary and legislative policies that eliminate exposure to SHS.  In, the workgroup developed various educational materials that addressed SHS messaging as well as held quarterly Technical Assistance calls to assist the field in their efforts.  The majority of was spent planning the statewide conference as well as providing technical assistance to the California Air Resources Board as they gathered information for their soon to be released report Environmental Tobacco Smoke Risk Reduction Plan.


Multi-Unit Housing Workgroup.  This 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 quarterly technical assistance calls to TCP-funded agencies, planning the statewide conference and developing a soon-to-be-released toolkit to assist the field to creating smoke-free multi-unit housing.


Tribal Casinos/Workplaces.  CTCP-funded agencies provided technical assistance to the National Conference of Legislators from Gaming States as they drafted and adopted a smoke-free gaming resolution.  The NCLGS resolution encourages lawmakers to include casinos and other gaming venues in smoke-free workplace laws.  In addition, it recommends that smoke-free air be included in state-tribal gaming compact agreement. The resolution is on-line at .


Secondhand Smoke Research.  CTCP-funded agencies have begun to work with the WinRiver Casino, in Redding, CA., and Dr. Neil Klepeis, from Stanford University, to do pre- and post-smoke-free casino policy air quality measurements.  The WinRiver Casino is slated to go completely smoke-free by June of .

Wildfire Information.  During the unprecedented wildfires that occurred in, Cal/OSHA issued a guidance document about protection of employees working indoors from the windborne smoke in terms of advisable approaches to modifying HVAC systems to cope with the problem.  The document discusses the problems posed by turning off HVAC systems or attempting to operate them in a full recirculation mode, and other issues that can be important in these situations.  


Indoor Air/Energy Code Review.  The Division was involved in reviewing the proposals for the California Building Energy Efficiency Standards (Energy Code).  Division personnel identified several concerns that were conveyed to the California Energy Commission.   


Heat Illness Prevention in Indoor Workplaces.  The Division has produced a guidance document for some indoor environments where heat illness can be a problem.  This can be found at   


Permissible Exposure Limit Revision Process.  The Division has convened a number of Health Expert Advisory Committee meetings to assess the need for adopting Threshold Limit Values recently issued by the American Conference of Governmental Industrial Hygienists for specific substances.  The next meeting has been scheduled for March 25, at 930 AM at the Elihu Harris State Building 1515 Clay Street, Room 1304 Oakland.  Some substances have recently been noticed for possible PEL setting by the Standards Board, docuemtation for this can be found at:

A complete list of current activities relating to specific substances can be found at 


Aerosol Transmissible Diseases.  The Division is in the process of formal rulemaking for an Aerosol Transmissible Disease Standard.  The proposal also addresses zoonotic diseases. The first proposal was noticed the comment period ended on August 21, at the Standards Board hearing.  Division staff are in the process of modifying the proposal in response to comments, and this revision will be noticed by the Standards Board this spring. The Board documentation for the proposed standards can be found at

California Energy Commission


 Obed Odoemelam ()


The California Energy Commission is required to develop cost-effective building energy efficiency standards that include both mandatory and performance requirements.  The Commissions Building Energy Efficiency Standards are specified in the California Code of Regulations (CCR), Title 24, Part 6 (also known as the California Energy Code). These standards are required to be revised periodically to allow consideration and possible incorporation of new energy efficiency technologies and methods.  One of the most important aspects of the Commissions building energy efficiency standards involves specific ventilation to ensure energy efficiency while maintaining healthy indoor air quality and thermal comfort. The Commission modified the ventilation requirements in its revisions of the standards through a process that allows for input from the industry, the general public, governmental agencies and specific stakeholders.

IAQ Tools for Schools (TfS) 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.


Tools For Schools Annual Meeting: Barbara Spark and Kathleen Stewart attended the 9th National IAQ Tools for Schools Symposium in Washington, DC, December 4-6,. They met with representatives from California  school districts (Pomona USD, Coachella Valley, and others) who were new to "Tools for Schools." We provide full Symposium scholarships to representatives of San Francisco USD and Pomona. A number of the Symposium presentations can be downloaded at The 10th National TfS Symposium will take place January 14-16,.


TfS Training and Presentations:  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.


High School presentations: Shelly Rosenblum gave lessons on indoor air quality to two AP science classes at Skyline High School in Oakland.  Shelly has been working with Earthteam, a coalition of Bay Area science teachers.  One of their projects, Something's In the Air, focuses on the air pollution - asthma connection.  As part of their lessons, the teacher had the students completing IAQ surveys in their other classes. Shelly is continuing this work.   More on training follows in other postings.


IAQ Tools for Schools (TfS)/California Teachers Association (CTA): CTA has been awarded another two-year grant from The California Endowment (TCE) for work on school IAQ/asthma. Barbara Spark and Shelly Rosenblum continue to participate in the project's planning committee, and link to individual school district initiatives via this project. 


CTA/Fairfield-Suisun Unified School District:   Fairfield-Suisun USD has become a model of district/teachers' union collaboration on implementation of  IAQ Tools for Schools. Susan White of the Solano Asthma Coalition, part of CAFA (Community Action to Fight Asthma) has played a major role in facilitating this project, with technical support from Shelly Rosenblum and Barbara Spark. As befits a successful project, upper management (the Interim Superintendent) was involved in the initial project meeting, along with Directors of M &O, Custodial Services, Purchasing and Risk Management, along with representatives of the Asthma Coalition, CTA, EPA, and importantly, the highly motivated local teachers union President. The district already had many excellent IAQ and green purchasing and cleaning practices in place, and thanks to union and asthma coalition engagement, has taken the additional step of involving teachers. We participated in the June 28 Solano County Asthma Awards luncheon, where Barbara Spark presented an IAQ TfS "Leadership Award" to the FSUSD Superintendent.


In an extension of union leadership at FSUSD, Fairfield-Suisun Teachers Union president Melanie Driver brought together teachers' union leaders from the Vacaville, Vallejo, Dixon, Travis and Benicia school districts to learn about IAQ Tools for Schools and opportunities for collaboration on Tools for Schools with us, the Solano County Asthma Coalition, and the CTA "Healthy Air, Healthy Kids" project. Shelly and Barbara gave presentations.


CTA/San Juan USD:  A TfS "pilot" project is underway at San Juan USD. The Indoor Environments Team met with Steve Duditch, President of the San Juan Teachers Association, and Don Myers, San Juan USD Facilities Director, to develop a plan for the union/district/EPA collaboration to implement IAQ Tools for Schools at this 78 school, 47,000 student district in Sacramento County. Janis Nielsen of CTA is assisting in this effort. The hope is to create a "model," very high profile TfS program, with a district IAQ team incorporating representatives from every stakeholder from the PTA to the School Board.  We provided a five hour IAQ TfS training workshop for 31 members of the San Juan Teachers Association on Saturday, November 15, with the participation of Bob Davis, the district's Director of Maintenance and Operations. 


CTA Outreach Video:  CTA is creating a DVD on the "Healthy Schools/Healthy Kids" IAQ/asthma project for internal distribution. Shelly Rosenblum was interviewed about IAQ TfS. 


California School Boards Association (CSBA):  School IAQ/Asthma and California School Boards Association (CSBA): CSBA has received a grant from The California Endowment to advance school policies on indoor air and asthma in California schools. CSBA brought in Dr. Joan Edelstein as their Senior Health Consultant. We've been working closely with this project, beginning with coaching on the history of IAQ efforts in California schools. CSBA is forming a Steering Committee to advance the school asthma objectives (including IAQ) in the Strategic Plan for Asthma in California. We've been participating in the planning group, which met with California Superintendent of Public Instruction Jack O'Connell in December. The Superintendent's office will co-chair this important initiative. 


IAQ Tools for Schools at Los Angeles Unified School District (LAUSD): Barbara Spark met in September  with Joel Jordan, Director of Special Projects and senior policy advisor to A.J. Duffy, the President of the 48,000 member United Teachers of Los Angeles (UTLA) union. Jordan agreed on the value of UTLA engagement with TfS at the district. However, the IET has put this collaboration "on hold" due to staffing changes in EH&S at the district, and distractions related to the current school budget crisis. In November, the LAUSD nursing program gave a TfS presentation to the district's Elementary Principals' Association, thanks to Association President Dr. Christopher Ortiz, an active member of the LAUSD IAQ Advisory Group. The principals were very responsive: about 50 expressed interest in implementing IAQ TfS at their school sites.


IAQ Tools for Schools at San Francisco USD: The IET has been supporting the efforts of Jacqueline Chan, the Indoor Air Quality Coordinator hired by the San Francisco Department of Public Health to assist SFUSD with implementation of Tools for Schools. This position was funded partly by a grant from our program. In particular, Shelly Rosenblum has provided coaching, walkthrough assistance, and training for site-based Coordinators.


IAQ Tools for Schools at  Santa Ana USD: Promising initial conversations on IAQ TfS were held with Camille Boden, Risk Manager for SAUSD, and Dr. Dave Barton, President of the SAUSD teachers' union.


IAQ Tools for Schools (TfS) in Kern County : Shelly Rosenblum and Barbara Spark provided a half-day TfS workshop for school district Superintendents and CBO's, hosted by the County Superintendent of Schools, in Bakersfield on February 15, . Also attending was the President of the CTA chapter at Kern H.S. district, the largest H.S. district in California.


IAQ Tools for Schools (TfS)/Sacramento area: Shelly Rosenblum and Barbara Spark provided a 5-hour IAQ TfS workshop for 21 school Risk Managers and Maintenance and Operations Directors from several area school districts on behalf of Schools Insurance Authority, a nonprofit insurer in Sacramento, on November 19,. Randy Smith from the University of Tulsa also presented and assisted with a demonstration school walk-through.




EPA National Asthma Forum:  Barbara Spark participated in EPA's 3rd national Asthma Forum, May 1-2, in Washington, DC. This very well-developed event reflected significant national progress in the development of asthma coalitions. We were able to provide only two Asthma Forum scholarships this year, one of which went to the Stanislaus County Asthma Coalition. Due to the budget situation, out of approximately 250 attendees, just ten were from California, including presenters. The National Asthma Forum will take place June 4-5, in Washington, DC. For more information:  


RAMP/CAFA:  Barbara Spark continues to serve on the Advisory Group for RAMP, the Regional Asthma Management and Prevention Initiative, which serves as the statewide coordinator of CAFA, Community Action to Fight Asthma. Barbara also participates in the Schools and Environment committees. RAMP has greatly increased the scale and scope of its activities, thanks for a major grant from CDC.




"Radon Leaders Saving Lives" campaign:  , EPA launched a new program which seeks to double effective actions taken by stakeholders to reduce radon risk in the next five years. 


EPA Audit of the California Radon Program:  The audit  revealed that the program is meeting or exceeding workplan goals. The audit also revealed challenges imposed by the on-going lack of a State budget at the time the audit was conducted. Even after the passage of the State budget, the monetary crisis looms large; the State Radon Program was temporarily cut in October but subsequently reinstated.
