A software-based (stand-alone and web-based) technology for the customized collection of complex occupant health symptom data among a cohort of occupants of any workplace or residential building is described. Unique design features and analysis methods in the software are employed to minimize sources of bias, confounding, and effect modification. The data are analyzed in comparison to a control population using multivariate statistical methods to identify and quantify the building-relatedness, determinants and distribution of occupants illness. The results of a case study is presented to highlight the power and utility of this new methodology, and its implications for diagnosing, treating, and preventing a significant amount of indoor air quality-related health complaints. Potential research and field applications of this technology in both problem and non-problem buildings are discussed.
EPA Healthy School Environments Assessment Tool (Beta Version)
Available for Testing. The U.S.
Environmental Protection Agency is developing a new, completely voluntary, and
fully customizable tool to help school districts conduct self-assessments of
their school facilities for potential environmental health and safety hazards.
The heart of the tool is a powerful database file that will let school districts
customize the tool to manage all aspects of a facility assessment program. The
tool comes pre- loaded with a checklist that integrates all of EPA's voluntary
and regulatory programs for schools, and is designed so that states and school
districts can incorporate their own policies and programs, producing a
customized checklist and reference guidebook. To learn more about the draft

Report to the Legislature on Indoor Air Pollution in
Air Purifiers that Generate Ozone Indoors
Back in January , staff presented information on portable air purifiers that purposely generate ozone indoors to the Board. They highlighted a U.S.EPA study that found some brands of these ozone generators can produce indoor ozone levels greater than three times the State ambient air quality standard of 90 ppb, one-hour average. The marketing for these devices has increased markedly in the last year, and is often targeted at vulnerable groups such as those with asthma and other respiratory disease. Staff concluded that agencies need clear regulatory authority to deal with this problem, and listed several brands and models of ozone generators currently on the market. The Board asked staff to seek action from the Attorney Generals Office, and to return with options for actions to address this public health problem at a future Board meeting. The staff presentation and Board press release are both available at
As a result of the Boards concern, a new web page has been developed proving links to general information on air purifiers and air cleaners as well as a list of air purifiers that purposefully generate ozone: .. ARBs Fact Sheet on Residential Air Cleaning Devices, , has also been updated.
Environmentally Preferable Purchasing (EPP) TASK FORCE
Staff from the Indoor Exposure Assessment Section attended several EPP Task Force meetings throughout the summer. The Task Force, chaired by CIWMB, has identified quick win projects to be completed in. The first project is to develop an on-line EPP Best Practices Manual that will be available to guide purchasing officials in their purchases. A draft guide on copier paper and other preliminary materials were reviewed. There are a number of categories related to IAQ planned for the EPP Manual, such as cleaning products, paints, inks, and office equipment.
We met with Sam Rashkin, director of U.S. EPAs Energy Star Program, who
visited CA to discuss a possible pilot program for EPAs new Indoor Air Quality
Package. The Package is an additional set of specifications builders can meet,
once a home design meets the energy conservation-related provisions under the
Energy Star program, to qualify for an Energy Star - Indoor Air Package
label. Homes built using U.S. EPAs indoor air specifications would have
reduced indoor emissions, improved exhaust ventilation for combustion
appliances, and other features to assure healthful indoor air quality as the
homes are tightened for energy conservation. USEPA is interested in a possible

Review Of Research Proposals for Energy commission
We reviewed four
exploratory research proposals for indoor air quality research for the
Environmental Exploratory Grant Program in the Public Interest Environmental
Research (PIER) Program of the California Energy Commission. The proposals
addressed topics such as improved air filtration in commercial buildings, the
impacts of alternative ventilation strategies on indoor PM levels, and the
relationships between mold and ventilation. The primary objective of this
program is to fund projects which will provide the foundation for more-focused,
larger-scale research development and demonstration projects that help resolve
the environmental effects of energy production and use. The program has five
focus areas: (1) indoor air quality; (2) outdoor air quality; (3) land use and
habitat; (4) aquatic resources; and (5) global climate change. This program is

Insulation Manufacturer Provides Products without Formaldehyde
In December, ARB staff met with representatives of Johns Manville to discuss their formaldehyde-free insulation and the ARB Indoor Air Quality Guideline, Formaldehyde in the Home. Johns Manville manufactures fiberglass insulation for buildings with an acrylic binder rather than a formaldehyde containing resin. The Johns Manville company made a decision to manufacture formaldehyde-free fiberglass insulation to provide a healthy product to consumers and to circumvent emission regulations at factory sites. Their product has been tested by an independent laboratory and found to essentially emit no formaldehyde.
EPA Symposium on IAQ Management for Schools
Tom Phillips attended the annual
symposium for Indoor
Air Quality (IAQ) Tools for Schools, sponsored by the USEPA and various
health and education organizations. This symposium focuses on preventing IAQ
problems in K-12 schools. Attendees included school personnel, and
representatives of teachers' unions, administrator organizations, and other
health and education organizations. USEPA developed the IAQ Tools for Schools
program, and sponsors this meeting to share practical information among all

As part of the settlement and resultant legislation for Uniform Complaint Procedures (UPC), school districts must respond in a timely manner to citizen complaints regarding immediate threats to health and safety in the classroom. These complaints may include IAQ issues. In addition, the complainant can appeal to CDE if they deem the district response to be inadequate and CDE then determines if the complaint/response is valid. CDE has received and is reviewing such complaint appeals (e.g., mold). If CDE finds that a complaint is valid and the district response inadequate, CDE must takes steps to investigate and make recommendations for remedy to the State Board of Education.
o AB315 (Hancock) has become a two year bill. This bill would require districts that use future statewide school bonds to follow CHPS guidelines concerning energy efficiency and IAQ for new construction projects. The Bill was amended to include a funding mechanism and eliminate the requirement for modernization projects. With these amendments the bill is now supported by various school interest representatives.
o AB1297 (Evans) was approved has been sent to the Governor. This bill would require inspection, maintenance or repair of HVAC systems by only school district employees or contractors who have been certified by certain associations. This bill has been opposed by various school interest representative because the requirements will be extremely expensive to implement and contains no funding provisions. It would be a reasonable guess that the Governor will veto this bill.
Previous USEPA and ASTDR investigations into NOA in the El Dorado Hills, including several schools sites, had determined that the levels detected were of concern and that precautionary mitigation and further health investigations and comparison with other areas were warranted. Recently the USEPA and ASTDR have reversed there earlier commitment to conduct comparison studies in other areas outside of the ElDorado Hills to determine if the results of activity based sampling are out of the ordinary. They have instead decided to use computer modeling based upon existing data. The affected districts have indicated their desire to pursue comparison studies and may challenge the prior study methods used which would overstate the presence of harmful types of asbestos. The Department of Toxic Substances Control (DTSC) has developed NOA draft Operation and Maintenance (O&M) guidelines for sites that have been remediated for NOA. Districts must commit to long term (forever) monitoring and reporting to confirm that NOA safety issues will not reoccur on the sites.
CDE has met with US EPA, reviewed HSEAT and has actively provided information to school district about the pilot tests and the upcoming release of the model.
CDE has a non-voting seat on the CHPS board. CHPS is currently updating it's Best Practices manuals. CDE has participated in the review and comment of "Volume 1 - Planning." CHPS has created a low-emitting materials list. In addition, CHPS has developed specifications for high performing relocatable classrooms.
The Division of State Architect (DSA) has been charged by the Governor to ensure that all state buildings are energy efficient, Executive Order S-20-04. To that end DSA has created the Green Action Team to recommend standards, etc. CDE is member of a sub-committee, the Schools Workgroup. Although Executive Order S-20-04 is more concerned with energy efficiency, the Schools Workgroup is recommending that the CHPS standards are adopted. If the CHPS standards are adopted for energy efficiency it should add more weight to their IAQ recommended standards, as well.
CDE has reviewed a June draft document prepared by ICG Consulting for the South Coast Air Quality Management District which provides guidance in selecting school site locations that mitigate effects of airborne pollution. CDE will continue to monitor and provide input as necessary.

Tire Derived Flooring Study
In June, OEHHA executed a contract with the Public Health Institute (PHI) funding a study of VOC emissions of tire-derived rubber flooring. The study is supported under OEHHAs cooperative agreement with CIWMB to develop indoor reference exposure limits (IRELs) for a set of VOCs, with funds from the Tire Fee Fund.
Under the PHI
contract, Weldon Hall and Paola Taranta were hired to
assist DHS staff in conducting the study.

DHS Standard Practice & Section 01350
DHS-IAQ continues to support implementation and applications of the DHS Standard Practice for the Testing of Volatile Organic Emissions from Various Sources using Small Scale Environmental Chambers,
The Standard Practice presently includes a copy of the Memorandum of Understanding (MOU) that was forged with the Carpet Research Institute for equivalency reference of the States 01350 requirements and testing protocols with those of the CRI Green Label Plus certification program. We are continuing to engage a variety of certification programs that currently reference the DHS Standard Practice or wish to in the future.

In August, DHS hosted a meeting with the Carpet Research Institute (CRI) at the Richmond Campus. Attendees included Frank Hurd from CRI, Bill Orr and Dana Papke of CIWMB, and Richard Lam of OEHHA. The meeting continued our dialogue on issues surrounding emission testing. Frank discussed the newly establish CRI Green Label for Adhesives: agreements had been reached with adhesive manufacturer for CRI to oversee the certification of VOC emission testing on all adhesive products, not only those used with carpets. DHS agreed to work with CRI to draft an MOU to incorporate into the current DHS Standard practice for use in Section 01350. DHS requested CRI to provide adhesives testing data from their present adhesives database to review. Data is needed to ascertain emissions on applications where the adhesives are used in assembly with carpet systems as there may be interactions with the carpet backings.
Also, we are working with CIWMB and others in establishing a broader certification standard that addresses all aspect of carpet sustainability, including IAQ. This Standard aims to combine the State EPP goals and the national Sustainable Textile Standards criteria, developed by The Institute for Market Transformation to Sustainability).
Meeting with Greenguard Environmental Institute
CIWMB hosted a meeting with Greenguards CEO, Carl Smith and Air Quality Sciences, CEO and Chief Scientist, Marilyn Black. Attendees included DGS, DHS, CARB, and OEHHA. Smith & Black gave a presentation on the general goals of Greenguard and its new initiatives. They were interested in moving toward harmonization between the Greenguard certification program and CA Section 01350. They described their recent applications to ANSI to develop 13 standards (3 are mold related) for certification and labeling programs with priority in the area of insulation, office furniture, and product emissions standard for children & schools. The children & schools appears to be the closest fit to CA Section 01350 requirements. It was noted that BIFMA has also made an ANSI application for office furniture. Some general discussion occurred on test duration difference (one week vs. 14 day) between the AQS testing and DHSs Standard Practice used for Section 01350.
Follow-up discussions will address review of test protocols and compiled data to compare 1-week vs 14-day test durations; the ANSI roadmap for their standard development process; and an open system for outside labs to have equal access to do Greenguard testing and meet quality standards for reliable testing. Greenguard has been asked to include State staff on the ANSI consensus team for the standard development.

The Division 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 final draft proposal was discussed by the
Occupational Safety and Standards Board at the hearing held on
Federal OSHA announced at the end of that it would be revoking its temporary standard pertaining to respirators used to protect employees from TB exposures, and apply the general industry respiratory protection standard to that segment of respirator users. This accompanied an announcement that OSHA would not promulgate a comprehensive TB standard as planned. The primary effect of this change was to require annual fit testing for respirators used during occupational exposure to TB.
In response to requests from the
regulated public made during this rulemaking, the Standards Board requested the
Division to conduct advisory meetings for developing a standard to regulate
exposures to airborne infectious diseases.
Consequently the Division has conducted several general meetings starting
Airborne Contaminants: 8CCR 5155.
The advisory committee ended its review process in March. A group of substances with PELs (permissible exposure limits) set at the TLV (threshold limit value) were first heard at the December Standards Board Hearing and adopted and the changes took effect in November. A second set of substances, including glutaraldehyde, which had PELs recommended at or below the TLV were reviewed at the Standards Board hearing on September 15, and final adoption is pending further review.

OEHHA Study on Fine Airborne Particles.
In one of the first studies of its kind, scientists at OEHHA and the University of California (UC) have found that fine particles emitted by motor vehicles and other sources may increase deaths from heart and lung ailments in California. The study found associations between levels of fine particles in nine California counties and deaths from heart and lung ailments in the general population of those counties, particularly among diabetics, people with respiratory and cardiovascular diseases, the elderly, and women. This study provides support for initiatives by both the state and federal governments in recent years to specifically regulate fine particles.

Reevaluation of 1,2-dichloroethane.
OEHHA has surveyed the scientific literature for recently published researched studies to determine if there are new toxicity studies on 1,2-dichloroethane that would warrant revising the Public Health Goal (PHG) of this chemical. New data were found that can provide some further insight on the toxic effects of 1,2-dichloroethane, but nothing was found that sheds any further degree of certainty upon the carcinogenicity status of 1,2-dichloroethane. Although there is no basis for proposing a change to the PHG, a few recent studies provide additional information on the toxicity of 1,2-dichloroethane. This 1,2 Dichloroethane PHG update including references is available on-line at .
GasolineRelated Emissions Document.
Gasoline powered vehicles emit a variety of volatile organic pollutants, including alkanes, alkenes, aromatic hydrocarbons and oxygenates. The pollutants that are emitted at the tailpipe and that evaporate from the fuel system are not necessarily the same as those to which the population is exposed, due to the atmospheric transformation processes that these pollutants undergo. The primary objective of this research effort was to identify atmospheric products associated with gasoline combustion and evaporative emissions that may pose a toxicological concern or may be present at relatively high levels in the atmosphere. A secondary objective was to assess the atmospheric lifetimes of gasoline-related pollutants, as constituents with longer lifetimes would be of greater exposure concern. The draft document Atmospheric Chemistry of Gasoline-Related Emissions: Formation of Pollutants of Potential Concern is available on-line at Chemistry Overview.

PNIER is a strategic document intended to capture the indoor environments research needs of all EPA offices with program responsibilities related to indoor environmental quality, and was developed with strong collaboration across several EPA offices. The needs are extensive and range from basic research on sources and emissions (including biological, chemical and particulate matter), through exposure characterization, health effects and mitigation techniques. It is anticipated that PNIER will articulate EPAs indoor environments research needs, for both internal and external uses; identify where knowledge gaps exist; help establish a more well-defined indoor environments research presence at EPA; facilitate collaboration between EPAs program offices and research laboratories; and possibly serve as EPAs foundation towards a larger federal cross-agency research strategy on indoor environments research.
