AGENCY REPORTS ON CURRENT IAQ ACTIVITIES

 

American Lung Association of California

-- Bonnie Holmes-Gen ()

 

Programs. About 2/3 of local lung associations in California are involved in the EPA IAQ Tools For Schools Program, and some are receiving grant funding from EPA.  The Program has recently been named a "Best Practices" Program of the national American Lung Association, which means that additional training and materials will be available to assist local lung associations in program implementation. Local lung associations are involved in additional indoor air quality efforts such as the American Lung Association of Central California's "Healthy Homes" program.  This program is designed to improve the quality of life for agriculture workers and their families through indoor air quality public education.

 

Legislation. The ALA-CA is sponsoring AB 2332 (Keeley), introduced in February.  This legislation would establish authority for the Air Resources Board to regulate indoor air quality and would require the board to set priorities and adopt indoor air pollution prevention and control measures to reduce emissions from products used indoors.

SB25 Indoor Monitoring Study. Field work is in progress for the SB25 indoor and personal monitoring study. The lead investigator, Dr. Steve Colome from UCLA, will measure PM2.5, PM10, elemental carbon/organic carbon, VOCs, carbon monoxide, and aldehydes at three schools in SB25 communities. Schools were selected in Boyle Heights and Wilmington in the Los Angeles area and Crockett in northern California. Two weeks of sampling have been completed at both Boyle Heights and Wilmington. Sampling is currently in progress at Crockett. At each school, weekly air samples are collected in three classrooms, one outdoor site on the school ground, and one residence.

 

Personal monitoring is also part of this study. This component will be initiated in the next visit to each school. Selected students will wear a passive VOC badge for 48 hours and complete a health status questionnaire to determine the incidence of asthma and allergy.

Informational meetings for parents have been held at two of the schools; thus far the schools and parents have been supportive of the study.

 

Portable Classrooms Study. The final report on the Phase I survey of building characteristics and 10-day formaldehyde levels is being prepared, and is expected to be released at the end of March. Public workshops on the report will be scheduled for late April. The Phase II field work has also been completed, and the samples and data are being analyzed. The final report to the Legislature will be submitted in June. See also related item under DHS.

 

Residential Indoor Cooking Exposure Study. The final report on an indoor cooking study conducted for ARB by ARCADIS Geraghty & Miller was released. Results showed very high levels of particles and elevated levels of formaldehyde, nitrogen dioxide, and some other pollutants emitted during certain common cooking activities. This confirmed that cooking can contribute significantly to pollutant exposures of the occupants, especially those of the cook. ARB has recommended practical ways that people can reduce indoor pollutant exposures during cooking. The report can be ordered from ARB or found on-line:

Outdoor Air Quality Particulate Matter Standard. The Air Quality Advisory Committee (AQAC) met with OEHHA and ARB staff in January to consider their draft proposal for possible revision to the State Ambient Air Quality Standard for Particulate Matter (PM). PM was previously identified as the highest priority standard to be reviewed under SB25, which requires, among other things, that ARB and OEHHA review traditional pollutants for their potential impact on children and other sensitive groups, and recommend changes to the standards, if needed, to assure protection of children and others. The AQAC was generally pleased with the draft document, but believed that a short-term PM2.5 (fine particle) standard is warranted by the existing data and needs to be included in the proposal. Staff are currently revising the draft proposal document and preparing responses to comments received on the draft, including responses to comments regarding the relationship among indoor, outdoor, and personal exposure concentrations of PM. The revised report is scheduled to be released in May, and is expected to be considered by the Air Resources Board for action at their June meeting.

 

Fresno Asthmatic Childrens Environment Study, or FACES. Investigators at UC Berkeley recently completed pilot efforts for the home intensive portion of the pollutant monitoring effort in this ongoing study, and have begun collecting detailed pollutant data at a subset of the homes of the participants. Additionally, ARB has assembled two mobile trailers with a full suite of air monitors and samplers, which will be deployed at schools throughout Fresno for the next 14 months.

EMF Mitigation. The SFPD has made recent progress with the proposed changes to department policy that would allow new school sites adjacent to power lines to perform a EMF mitigation plan and by doing so possibly reduce the required set back distance from power lines. Two large So. California. school districts have proposals submitted and they are being evaluated at this time.

 

High Performance Schools. The SFPD continues to provide input to the CHPS group for energy efficient classrooms and will continue to lobby for incorporation of best IAQ standards as part of the energy efficiency standards.

Chemical Terrorism Preparedness. EHIB personnel are currently involved in preparing materials for multiple focus areas of this grant including preparedness planning and readiness assessment, surveillance and epidemiology capacity, Health Alert Network/communications and information technology, risk communication and health information dissemination and health professional education/training. In addition, staff from DHS EHIB and Communicable Disease Control Division are responding to the most recent request for grant applications by the Center for Disease Control and Prevention (CDC). This grant will provide supplemental funds for public health preparedness and response to biological, chemical and other forms of terrorism.

 

Asthma Resources. Along with DHS Chronic Disease Branch, EHIB staff have been developing an asthma resource list that will provide information on the types of services or information available from state and local government agencies as well as community based organizations in California that serve clients with asthma. This list can be seen on the EHIB web site by going to the Topics page and selecting the bullet titled, Asthma Services by County. This list will provide the basis for developing a statewide asthma partnership and offering these partners a number of web-based services.

 

Presentations. Sandy McNeel discussed health effects of fungi and other indoor allergens at the U.S. EPA-sponsored conference, Indoor Air Quality: Asthma and Allergens, in Fullerton, CA, January 22 & 23,.

BASE Study. We have began analysis of wet and dry bulk samples in the 100 building data set. An abstract entitled, Exposure to Bioaerosols in 100 Large U.S. Office Buildings was submitted for the ISEA/ISEE joint meeting, August 1115,.

 

Environmental Tobacco Smoke (ETS) Study. We are requesting a 1-year, no-cost extension from TRDRP so that we can study few more actual smoking rooms. We are planning to investigate 1 or 2 smoking rooms at out-of state locations, likely Nevada.

 

Emissions of Building Materials With High-Recycled Contents. In the CIWMB funded study to measure emissions of building materials with high recycled contents and compare them to their virgin counterparts, staff has completed Phase I of this study (materials used in portable classroom construction). We have tested a total of 19 building materials. The Phase I draft report is due to the CIWMB on March 15. We anticipate having the Phase I final report available in late spring. We have started contacting manufacturers for samples to be tested in Phase II of the study. This phase focuses on materials characteristic to state office building construction.

 

Portable Classroom Study. A set of abstracts related to the PCS were submitted to be included at the ISEA/ISEE joint meeting, August 1115,.

         How Public Agencies Address Indoor Mold Hazards in California

 

 

California Department of Health Service / Occupational Health Branch

-- Jim Cone (), and Liz Katz ()

 

Playground Surfacing Product Sickens Worker. A contractor employee was hospitalized with a severe respiratory illness after he applied a polyurethane resilient coating product to a playground. The product's active ingredient is MDI (methylene bisphenyl isocyanate) in a pre-polymerized form which has traditionally been considered safe. The monomeric forms of isocyanates are extremely hazardous; isocyanates are the leading cause of occupational asthma. In response to this incident, HESIS is investigating the under-appreciated toxicity of pre-polymeric forms of isocyanates.

 

Pollution Prevention: Collaborative Activities. DTSC's Office of Pollution Prevention and Technology Development is developing a pamphlet for the jewelry industry addressing environmental pollution issues. HESIS helped DTSC integrate worker health and safety and pollution prevention information in the pamphlet to help protect workers and to simplify regulatory compliance for employers in Southern California.

 

Less-toxic Alternative Chemicals. Cal/EPA Office of Environmental Health Hazard Assessment is preparing an environmental justice demonstration project with a community group near San Diego. HESIS provided information on less-toxic alternative chemicals for businesses such as dry cleaners and auto repair shops.

New Tobacco Control Law. In January, AB 188 (Vargas) went into effect, prohibiting smoking a cigarette, cigar or other tobacco-related product within playgrounds and tot lots in parks. In addition, the law prohibits the disposal of cigarette butts, cigar butts or other tobacco-related waste within these areas. Violators of the law are subject to a one hundred dollar ($100) fine. The local governing body determines enforcement of the law. . The new law added Section 104495 to the Health and Safety Code.

 

In order to promote this law, a mass mailing to the following groups will be distributed in February: Head Start Grantees, WIC Program Directors, Police Chiefs, County Sheriffs, Parks and Recreation Officials, City Managers, Mayors, Day Care Providers, and County Boards of Supervisors. Enclosed with cover letters describing the law will be a fact sheet of H.S. Code Section 104495, a copy of the chaptered legislation, and information on ordering promotional stickers and camera-ready copies of signs from their county/city tobacco control programs. In addition, a Communications Kit, developed by Rogers and Associates, was distributed to all CDHS/TCS-funded programs in December . The kit described the new tobacco control laws that were signed into law in, including HS Code 104495. The kit included a quick-reference summary of the law, a swiss-cheese press release for programs to submit to local media, sample letters to the editor, talking points, a fact sheet about the new law, and an order from TECC (Tobacco Education Clearinghouse of California) for camera-ready signage and promotional stickers in English and Spanish.

 

Enforcement Grants. The law enforcement grants awarded by CDHS/TCS represented a new effort to increase compliance with the state and local secondhand smoke and other tobacco-related laws. The awarded agencies included 4 local health departments, eight police departments, two county sheriffs offices, one fire department, and one District Attorneys office.

 

Updated California Smoke-free Workplace Law Brochure. When the California Smoke-free Workplace Law first went into effect in, a brochure was developed to educate the public about the various provisions of the law. Since that time, the smoke-free bar provision went into effect, thereby outdating the original brochure. In, another version of the brochure was developed with the assistance from the Secondhand Smoke Workgroup, an expert body convened to provide CDHS/TCS advice and technical assistance in developing campaigns and materials focusing on secondhand smoke. This brochure has been widely disseminated throughout California and to other states.

 

AB 13 Case Study. In, a case study was written to describe the actions taken by the California Tobacco Control Program, in concert with county health departments throughout California, to prepare for the statewide ban on smoking inside bars, taverns and gaming clubs. The Case Study describes the groundwork conducted for smoke-free workplaces, the legislative chronology to achieve the statewide law, implementation strategies, public support, and the economic and public health impact. The Case Study has been a useful tool for other states as they embark on the road to smoke-free bars, and as a lesson to Californians on how to successfully implement complex and political tobacco control policies.

 

California Lessons in Clean Indoor Air. A companion piece to the AB 13 Case Study is California Lessons in Clean Indoor Air, a manual developed in May. It consists of a compilation of campaign stories, implementation tools, and compliance strategies to implement local smoke-free laws. Developed by a LLA project director who interviewed 53 veterans of Californias tobacco control campaigns, the manual provides an insiders view on what is involved in working toward local clean indoor air policies.

 

 

Local Program Activities. CDHS/TCS emphasized the importance of secondhand smoke interventions in its LLA Guidelines. In putting together their new comprehensive plans, LLAs were required to assess four CX community indicators related to secondhand smoke: 1) the extent of enforcement/compliance of state/local smoke-free bar and gaming law(s); 2) the extent of compliance with the state law that prohibits the use of tobacco by all students, school staff, parents and visitors in public school district-owned or leased buildings, on district grounds, and in district vehicles; 3) the proportion of homes with a smoker in the household who report their home is smoke-free; and 4) the extent of outdoor recreational facilities (e.g. fairgrounds, amusement parks, playgrounds, sport stadiums, etc.) that have policies designating a portion or all the outdoor areas as smoke-free. LLAs could also assess other secondhand smoke-related indicators if they desired.

 

The social norm change approach that CDHS/TCS requires of its local projects is most often operationalized through adoption and implementation of policies. This focus is clearly seen in the continuing adoption of polices related to secondhand smoke at the local level. As of July, 325 local clean air ordinances had been established in California. Of those, 22 applied to outdoor areas.

Secondhand Smoke Field Poll. In January, the Field Research Corporation conducted a survey of opinions Californians have regarding exposure to secondhand smoke. The survey of 1,812 adults was conducted using a random-digit-dial telephone survey process. Statewide data and select regional data were gathered for eleven outdoor and indoor environments, essentially areas not currently regulated by state law. These included building entrances, outdoor dining areas, nursing homes, playgrounds, patio dining, entertainment venues, casinos, apartment common areas, apartment units, hospitals, and campus housing. The data indicates a very high degree of public support for protection from SHS in these environments. For example, over 88% agreed that playgrounds and other child play areas should be smoke-free within a minimum of 15 feet from the edge of play areas. Approximately 90% agreed that nursing homes and other long-term health care facilities should be smoke-free. Approximately 86% agreed that hotel and motel lobbies and common areas such as swimming pools and fitness rooms should be smoke-free. The survey sample was selected to be representative of the entire state as well as for eight geographic regions. With two exceptions, the regional data sets represent the CDHS/TCS-defined geographic regions.

 

Secondhand Smoke Conference. On May 30-31, in San Diego, CDHS/TCS held the first national secondhand smoke (SHS) conference. The two-day event was attended by over 500 people from throughout the country and several foreign countries. The conference is a requirement in CDHS/TCS grant with the Centers for Disease Control and Prevention to provide national tobacco control technical assistance. The conference featured sessions on: community organizing around SHS; facing, countering and surviving industry opposition; SHS policy development and advancement, both voluntary and legislative; reducing in-home SHS exposure; successful ethnic community SHS campaigns: getting the media interested in SHS; outdoor tobacco smoke issues, developing SHS educational materials; preemption; following up on the September statewide SHS conference; legal tools to enhance compliance with SHS laws; and SHS reduction strategies in rural environments.

 

Media Campaign. The Tobacco Education Media Campaign produced 22 television, radio, outdoor, and print ads last year to support the programs' efforts in secondhand smoke strategy both in the workplace as well and outdoor public places. Ads were produced in English, Spanish, Korean, Vietnamese, Mandarin, and Cantonese in this category. With regard to print, ads were also produced in Tagalog, Japanese, Thai, Cambodian, and Hmong languages.

Airborne Contaminants: 8CCR 5155. The Division continues to review more Threshold Limit Value changes proposed by the ACGIH. The first meeting of the advisory committee was on May 4,. The next meeting is tentatively set for May 3, in San Francisco at the state building headquarters. The Division coordinator is Bruce Wallace who can be reached at .

 

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. The Division coordinator is Bruce Wallace who can be reached at .

 

Heat Stress Standard. The Division has held four 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.

 

Revision of the Sanitation standard, GISO 3362. HESIS proposed language to the Division to change the sanitation standard to specifically identify mold as an unsanitary condition that must be corrected by the employer. This was proposed as a clarification to the existing standard to the Cal/OSHA Standards Board on September 20th. In response to the comments that were received on the proposal, the Board asked the Division to have an advisory meeting to consider more information about the proposal. This advisory meeting was held on Tuesday, November 13th at 10 AM in the Oakland State Building.

 

The proposal considered at the meeting was as follows:

 

Title 8, Calif. Code of Regulations; General Industry Safety Orders: Article 9 Sanitation, 3362. General Requirements.

(f) Every enclosed workplace and personal service room shall be equipped and maintained, insofar as is practicable, to prevent the entrance or harborage of insects, rodents or other vermin. An effective program of extermination and control shall be instituted whenever their presence is detected. When exterior water intrusion, leakage from interior water sources, or other uncontrolled accumulation of water results in mold infestations on interior building components or furnishings, the water intrusion, leakage, or accumulation shall be corrected, the mold shall be cleaned or removed, and water damaged components shall be repaired or replaced as necessary to prevent the regrowth of mold.

 

As a result of the discussion at the meeting, this proposal was revised and is being prepared for a 15-day public comment period that will be set by the Standards Board.

 

Revision of Recordkeeping requirements. In keeping with a Federal OSHA mandate, the recordkeeping requirements for injuries and illnesses in California workplaces have been revised and were adopted on January 2,. This includes replacing the Log 200 with a Log 300 form and revising recording criteria, access requirements, and new recording requirements. These changes affect most of the employers in California. These changes can be viewed on-line at:

LAUSD Office of Environmental Health and Safety Website. The Los Angeles Unified School District's Office of Environmental Health and Safety Website just went online. While they are still populating a number of the sections, it already has some great information. Over time, they will be adding a wide range of data and information. Of particular use are the most recent version of their Safe School Inspection Guidebook, the Standard Emergency Procedures for Schools, and Safety Grams. See

 

LAUSD IAQ Advisory Group. This Group is comprised of district staff from OEHS, Medical Services and UTLA, with staff from ALA-LAC, U.S. EPA Region IX, SCAQMD, and CARB, plus community members. The focus is to support in outreach and education on the Tools for Schools (TFS) and Open Airways (OA) programs. An outreach memorandum, with an attachment to request assistance with either TFS or OA, to was sent to all school/site administrators in February. Since then, we have received 73 requests for information and/or implementation assistance for both programs. All of these requests have been forwarded to ALA-LAC to begin the outreach process.

Chronic Reference Exposure Levels (RELs) for Airborne Toxicants. The Scientific Review Board reviewed a number of proposed chronic RELs and at its November 28, meeting, endorsed 12 additional chronic RELs, bringing the total number to 72. Additional RELs are currently undergoing review. The toxicants with new chronic RELs are acrylonitrile, beryllium and beryllium compounds, chloropicrin, diethanolamine, ethylene dibromide, isophorone, maleic anhydride, methyl isocyanate, 4,4-methylene dianiline, selenium and selenium compounds, sulfuric acid, and vinyl acetate. Some of these chemicals are known or potential indoor air pollutants. Summaries are available at:

 

East Bay Children's Respiratory Health Study. This cross-sectional study of school-aged children examines the relationship between respiratory health and exposure to traffic-related air pollutants. Ten schools in a Northern California area were selected based on their proximity to major roadways. Approximately 1600 third- and fourth-graders participated. The child's respiratory health and his/her home environment will be assessed through parental responses (questionnaire). The parental health questionnaire data are being analyzed. Preliminary results show several factors are associated with bronchitis symptoms: parental health history of asthma, building history of water damage, and the presence of mold and pests in the home within the previous 12 months. The location of the school is associated with current physician-diagnosed asthma. The final outdoor air pollution monitoring was conducted in the Fall. Preliminary results of air pollutant analysis show that only NOx was weakly associated with an increased prevalence of bronchitis symptoms. Currently, we are planning for the neighborhood air monitoring study with the goal of exploring the spatial variability of pollutants in the neighborhoods where the study population resides.

 

Ambient Air Quality Standards for Particulate Matter and Sulfates. The Staff of OEHHA and ARB in November released a report including quantitative risk assessments and recommendations for standards for PM10 and PM2.5:

     PM10 Annual-average Standard: 20mg/m.

     PM10 24-h-average Standard: 50mg/m (retain previous standard).

     PM2.5 Annual-average Standard: 12mg/m.

     PM2.5 24-h-average Standard: NO recommendation.

     Sulfate 24-h-average Standard: 25mg/m (retain previous standard).

 

Moving current levels of PM10 and PM2.5 in California to attainment of the recommended standards was estimated to result in a reduction of 6500 cases of premature mortality per year. The corresponding estimated mean annual reductions in hospitalizations were 600 for chronic obstructive pulmonary disease (COPD), 900 for pneumonia, 1500 for cardiovasculsr disease, and 500 for asthma cases. Among children ages 7 14, attainment of the PM2.5 standard was estimated to result in about 209,000 less days of lower respiratory symptoms per year. The full document is available at .

 

Although CalEPA staff report did not recommend establishing a PM2.5 24-h-average standard in the report, at their January 23-24, meeting, the Air Quality Advisory Committee (AQAC) directed them to do so. The proposed value for this new standard is expected to be available in March.

 

Art and Craft Materials List. A new list of art and craft materials, which cannot be purchased or ordered for use in kindergarten and grade one through six, is now available. The Guidelines for the Safe Use of Art and Craft Materials has also been updated. They are available at:

 

Proposed Clarifying Regulations for Proposition 65. On November 2, OEHHA convened a public workshop to solicit input on a proposal in a first in a series of clarifying regulatory amendments. In an effort to continue the orderly process of considering amendments to the Proposition 65 regulations, OEHHA announces the availability of the second draft regulatory amendment package, which is available for downloading at:

A public hearing will be held on Monday, March 18, at 10:00 am (1001 I St, Sacramento). Following the public hearing OEHHA has scheduled to receive testimony on the first set of clarifying regulatory amendments.

 

Others items:

         A fact sheet, Air Pollution and Childrens Health, was recently released by OEHHA and the American Lung Association, available on-line at:

         A booklet, A Guide to Health Risk Assessment, was published by OEHHA to provide a basic explanation of risk assessment for laypeople involved in environmental health issues, including policymakers, businesspeople, members of community groups, news reporters, and others with an interest in the potential health effects of toxic chemicals. Available for downloading at: .

         Staff of OEHHA has reviewed toxicity information for PureDry, a candidate alternative solvent for dry cleaning.  PureDry contains odorless mineral spirit, HFE-7200 (a mixture of ethyl perfluoroisobutyl ether and ethyl perflurobutyl ether), FC-43 (perfluoro compounds of primarily 12 carbons), PF-5070 (perfluoro compounds of primarily 7 carbons), and PF-5060 (perfluoro compounds of primarily 6 carbons).  Based on the reviewed of available literature, OEHHA staff are concerned about the neurotoxicity of mineral spirits and the environmental persistence of perfluorinated chemicals in the product.

Data Validation for Random Component Superposition (RCS) Model. Wayne Ott sent a written request to Ethyl Corporation to obtain the personal exposure, indoor, and outdoor PM-2.5 concentration measurement and activity pattern data from the large population exposure field surveys conducted by Ethyl and Research Triangle Institute in Toronto, Canada, and Indianapolis, IN. It is hoped that these personal exposure and indoor field data can be used with the Random Component Superposition (RCS) model for particles under 2.5 micrometers (PM-2.5). That model was applied successfully to PM-10 in Riverside, CA; Toronto, Canada; and Phillipsburg, NJ, and the RCS model offers the possibility of extending the findings from one population exposure field survey to the populations of other cities.

 

Indoor Air Paper. Paul Switzer, Sandra McBride, and Wayne Ott submitted a research paper to Indoor Air on the Mixing Characteristics of a Continuously Emitting Point Source in a Room. This paper includes time delay statistics based on past indoor experiments on the times at which pollutants travel across a room (that is, their "first hit" times at a monitoring location in the room). The first hit times may permit development of a new model describing the mixing times of indoor pollutants and may help explain the error in indoor air quality models based on the mass balance equation and its assumption of uniform mixing.

IAQ Tools for Schools hotline. A technical and non-technical "hotline" for questions about school IAQ and implementation of the IAQ Tools for Schools Action Kit program has been funded by EPA at the University of Wisconsin at Madison, College of Engineering, HVAC and Research Center. This group has run tech hotlines for ASHRAE and EPRI. This service is available both to school personnel seeking assistance about implementing the Tools for Schools program, and those simply seeking answers to school IAQ questions. The phone number is 866-TFSEPA1 . We welcome assistance in getting the word out on this service. Reminder: the IAQ INFO Clearinghouse answers general IAQ questions and provides copies of many EPA IAQ documents and fact sheets to all stakeholders.

 

Indoor Air Quality Tools For Schools. We are entering a new phase in our efforts to encourage school districts to fully implement the IAQ Tools for Schools (TfS) Action Kit program. Our training and outreach efforts, and those of our American Lung Association grantees, have resulted in widespread use of the parts of the Kit, which help maintenance and operations personnel to improve school IAQ, but implementation at the all-important school-site classroom level has been harder to achieve. We are now making significant progress in bringing together institutional support for full implementation, as noted below.

 

EPA Regional Administrator (R9) Tools For Schools Initiative. Our new Regional Administrator, Wayne Nastri, has decided to become personally involved with our outreach efforts on TfS. He will be directly engaged with efforts in four school districts in our region, 2-3 of which will be in California (including LAUSD). Our strategy includes developing multifaceted local initiatives which include engagement by local government leaders, leadership by statewide governmental agencies and statewide school decision-maker associations, and local health and environmental entities, and community groups. We are working closely on this project with Bill Jones, R9 schools liaison, and our Public Affairs department.

 

Partnerships with Statewide Organizations. We are in the process of formalizing partnerships with major statewide organizations of school decision-makers: California Association of School Business Officials (CASBO), Association of California School Administrators (ACSA), and California Schools Boards Association (CSBA).

         CASBO - A joint letter encouraging implementation of IAQ TfS signed by our Regional Administrator, Wayne Nastri, and the Executive Director of CASBO, Kevin Gordon, will shortly be mailed to Superintendents and Chief Business Officials in every California school district. An MOU detailing a multi-faceted CASBO/EPA partnership is in the works. We also facilitated a meeting between CASBO officials and a number of elected County School Superintendents and EPA Administrator Christine Todd Whitman and other EPA officials in Washington, DC.

         CSBA - CA School Boards Association officials and a number of district School Boards presidents recently met at EPA HQ with Indoor Air and Childrens Health representatives to discuss EPA programs available to support local efforts to support childrens environmental health. The IAQ TfS program was met with great enthusiasm, resulting in CSBA assigning a liaison to work with our Team on collaborative efforts.

         ACSA - The Association of California School Administrators is a very large organization representing not only district superintendents, but all Elementary, Middle and High School principals in the state. We met with ACSA officials (and the CSBA liaison) to describe the TfS program and discuss future collaboration. An MOU is now in development with ACSA, and weve been invited to write articles for their two publications.

 

EPA Healthy Schools Initiative. EPA has launched a multi-faceted schools initiative designed to bring school related programs into sharper focus and help schools put environmental issues into the broader context of their fundamental goal of teaching children. The initiative will utilize many of the principles of High Performance Schools in which planners and other key players in the school community take a "whole-buildings" approach to considering key building systems and technologies together to ensure that the impact of these systems and the building as a whole on occupant, health, comfort, and productivity is understood and optimized at each stage of a building's lifecycle. New web-based guidance on school design, construction, and renovation is now in development and will focus on ensuring superior indoor air quality within the context of energy efficiency and other issues of critical importance to schools. This guidance will be completed and online Summer. A "one-stop shopping" web portal site on school environmental health issues will also be online in the summer of, permitting those interested in school environmental health issues to find resources available from EPA, other Federal Agencies, States, and non-governmental organizations through a single access point.

 

Schools Workgroup to the Children's Health Protection Advisory Committee (CHPAC). The CHPAC advises the EPA Administrator on Children's Health Issues and formed a schools workgroup to provide recommendations addressing how schools should be designed, built and maintained to prevent or minimize exposures and what research needs to be done. The workgroup is finalizing the letter and a final set of recommendations should go to the Administrator within the next month or two.

 

The President's Task Force on Environmental Health Risks and Safety Risks to Children. Established by Executive Orders 13045 and 13229, the President's Task Force on Environmental Health Risks and Safety Risks to Children is charged with recommending to the President Federal strategies for protecting children's environmental health and safety. The Task Force is Co-chaired by EPA Administrator Christine Todd Whitman and the Secretary of Health and Human Services, Governor Tommy Thompson. In October, the Task Force principals met to identify priorities for the coming year. In addition to committing to implement the national lead and asthma strategies, the Task Force also recognized the unique problems and needs of the nation's schools by establishing a new working group, co-chaired by the Environmental Protection Agency, the Department of Education, and the Department of Health and Human Services. The workgroup will likely have a strategy document drafted by late Summer.

 

Federal No Child Left Behind Act of. The No Child Left Behind Act of (Public Law 107-110), signed into law by the President on January 8, includes two important provisions that will directly impact school environmental health as well as the agenda and work of the Task Force Schools Workgroup. Section 5414 requires that the Secretary of Education conduct a study regarding the health and learning impacts of environmentally unhealthy public school buildings on students and teachers. The study must include the characteristics of public schools that contribute to unhealthy schools, health and learning impacts of environmental unhealthy public school buildings and recommendations to Congress on how to assist schools that are out of compliance with federal and state health and safety codes, and a cost estimate of bringing up the unhealthy schools to the minimum federal health and safety building standards. The report is to be completed 18 months after enactment. The Act also authorizes the Department of Education, in consultation with EPA and the Department of Energy, to award grants to state educational agencies to plan and prepare for healthy, high-performance school building projects that: 1) reduce energy use to 30% below that of a school construction plan as outlined in Chapter 8 of the International Energy Conservation Code; 2) meet Federal and state health and safety codes; and 3) support healthful, energy efficient, and environmentally sound practices.

 

Los Angeles Unified School District's Office of Environmental Health and Safety Website. The Los Angeles Unified School District's Office of Environmental Health and Safety Website just went online. While they are still populating a number of the sections, it already has some great information. Over time, they will be adding a wide range of data and information. Of particular use are the most recent version of their Safe School Inspection Guidebook, the Standard Emergency Procedures for Schools, and Safety Grams. See

 

Environmental Livability and Smart Schools Symposia. The first of at least two Environmental Livability and Smart Schools Symposia in CA took place last Tuesday, December 5 in Los Angeles. The second symposium took place on February 26 in Sacramento and focused on the specifics of getting Joint Use/Schools as Centers of Community and High Performance School Design and Construction incentives in legislation.

IAQ: Asthma and Allergens Course. Our University of Tulsa provided course in Fullerton, California January 22-23, provided excellent opportunities to reach new audiences, with people new to EPA training making up the vast majority (perhaps 80% or more) of the 220 people attending. There was significant participation by health providers and educators, for example physicians, Public Health Directors, HMO asthma educators, and community asthma workers. Schools were represented by school nurses and risk and maintenance managers and staff. Thanks to outreach by the California Apartment Association, there was attendance by a number of apartment management companies.

 

Ozone Generators. Recently, there has been publicity concerning the purchase of ozone generators by a California public school to combat mold. We recently learned from colleagues in Atlanta and Chicago that these devices have been marketed with the EPA Logo and/or an EPA registration number. Everyone should be aware that EPA does not endorse these devices and recommend against using them in occupied space. The Federal Trade Commission fined a major manufacturer, Alpine, for misleading advertising. If anyone should see such a device being sold with the EPA Logo or any EPA registration numbers, etc. please notify Shelly Rosenblum () at .

 

If anyone should see such a device being used in homes, offices or schools, please explain to the user that ozone is ineffective in dealing with indoor air problems and should not be used in occupied spaces. Refer them to our website for more information and as well as links to other agencies' statements on ozone generators.

State Blueprint for Sustainable State Facilities.. The States Sustainable Building Task Force released their comprehensive plan to transform Californias state-owned buildings into state-of-the-art facilities designed to save precious environmental resources and taxpayer dollars. The report, Building Better Buildings: A Blueprint for Sustainable State Facilities (Blueprint), was release during the East Ends Topping Out Ceremony on December 19, and recommends a 10-point plan to implement the sustainable building goal set forth by the Governor in Executive Order D-16-00. This report is a powerful testament to the benefits of sustainable buildings, as well as partnerships among diverse agencies that come together to solve problems and produce outstanding results, said Aileen Adams, Secretary of the State and Consumer Services Agency and chair of the Task Force. The interagency task force of more than 32 governmental departments represents the best in government -- a unique partnership, whose combined expertise in environmental, facilities, and fiscal matters -- is truly helping to improve our buildings and our environment.

 

 

The Blueprint emphasizes sustainable building strategies that include:

        Modifying the states capital outlay policies and process to incorporate sustainable building goals;

        Incorporating integrated design, life cycle costing, building commissioning, and post occupancy evaluation processes into the states capital outlay program;

        Developing cost-effective building performance standards to measure the effectiveness of sustainable building practices;

        Establishing a systematic reporting and review process to ensure that state building performance improves continuously;

        Developing exemplary projects and model sustainable buildings that demonstrate the effectiveness of sustainable building and operating processes; and

        Assisting state agencies in the development of sustainable building projects.

The Task Force continues to meet to discuss the various deliverables shown in this report, most recently on March 5, to assess progress towards implementation of their specified plan.  The report can be found at:
