89-7-1 Report on Reducing Exposures to Indoor Air 001
Pollutants in California: Existing Authorities
and Recommended Actions.
89-7-2 Presentation on the Feasibility of Economic
Incentives as a Means to Reduce Emissions.
PUBLIC MEETING TO CONSIDER INFORMATION AND RECOMMENDATIONS
REGARDING REDUCING EXPOSURES TO INDOOR AIR POLLUTANTS IN
CALIFORNIA: EXISTING AUTHORITIES AND RECOMMENDED ACTIONS.
Board staff proposes a number of recommendations for actions
which can be taken by the Board to assure the reduction of indoor
exposures to pollutants in California. Staff recommends that the
Board: accept and endorse the findings and recommendations of the
report; direct staff to develop, in conjunction with other state
agencies, a state plan for action to assure reduction, and where
feasible prevention, of exposure to indoor air pollutants; direct
staff to develop, for Board endorsement, health-based indoor air
quality guidelines for non-occupational indoor environments;
recommend that clear regulatory authority be established within a
single state agency to reduce exposures from indoor sources of
pollutants such as consumer products and home furnishings; direct
staff to assist other government agencies with indoor air quality
education programs; and direct staff to seek additional funding
for indoor air quality research.
General recommendations for actions which may be taken by others
are also presented in the report.
In May, 1987, staff presented information to the Board regarding
the health effects and indoor concentrations of air pollutants
and issues surrounding indoor air quality, including the limited
authority of government agencies to deal effectively with indoor
air quality problems. Examination of available information
indicated that indoor air pollution poses a serious risk to human
health in addition to the known risks from ambient (outdoor) air
At the Board's request, staff has prepared this follow-up report
which examines the various authorities and activities of federal,
state, and local government agencies related to indoor air
quality, and assesses the need for further authority and/or
actions on the part of California government. Draft versions of
this report were reviewed by the agencies discussed in the
report, and all comments received were considered by ARB staff in
preparing the final report.
No federal or state agency has explicit authority to regulate
indoor air quality. At the federal level, indoor air quality
activities are coordinated through the interagency Committee on
Indoor Air Quality, which is chaired by the U.S. Environmental
Protection Agency (EPA) and which includes representatives from
16 different federal agencies. In 1987, EPA produced an Indoor
Air Quality Implementation Plan which indicates that EPA will
address indoor air quality through continued research development
of mitigation techniques, and transfer of information to state
and local governments. The Plan clearly indicates that actual
mitigation of indoor air quality problems will be left to state
and local governments.
In California, no state plan or formal process has been developed
to address indoor air quality problems in a comprehensive way.
Since 1983, the Department of Health Services (DHS) has had
authority to conduct indoor air quality research and to
coordinate the state's response to indoor problems. DHS chairs
the California Indoor Air Quality Interagency Working Group
(IWG), and informal group of state agency representatives who
meet at least quarterly to discuss indoor air quality issues.
Local governmental units have taken significant actions to reduce
exposure to environmental tobacco smoke through passage of many
city and county ordinances which restrict cigarette smoking.
However, local government has neither adequate resources, nor in
most cases, adequate expertise to address the breadth and
complexity of indoor air quality problems and issues that face
the state today. Although local government may be the best body
to implement some indoor air quality mitigation measures, state-level
action and technical and financial assistance appear
