ITEM NO.: 90-1-2
Public Hearing to Consider Adoption of Regulations Regarding Test
Methods for Determining Emissions from Nonvehicular Sources.
STAFF RECOMMENDATION
The staff recommends that the Board adopt one new test method,
add two new references to existing methods, amend six existing
test methods, and incorporate the methods by reference in new
Sections 94146, 94148, and 94149, and amended Sections 94002,
94003, 94132, 94135, 94139, and 94140, Title 17, California Code
of Regulations.
DISCUSSION
Determinations of gaseous and particulate matter emissions from
nonvehicular sources (stationary sources) are commonly called
"source tests" and are conducted to ascertain whether a source is
complying with air pollution control laws and regulations. The
Board is authorized by Health and Safety Code Section 39607(d) to
adopt procedures ("test methods") by which source tests are
conducted. Since 1972, the ARB staff has developed and the Board
adopted five test methods for the gasoline vapor recovery program
and 45 test methods covering a wide variety of stationary
sources.
The ARB staff is now proposing the adoption of a new ARB test
method, Method 434 - Determination of Chlorine in Unheated Air.
This proposed method has been adapted from a method developed by
the National Institute of Occupational Safety and Health.
The staff originally proposed that the Board consider the
adoption of another new method as well, Method 435 -
Determination of Asbestos in Bulk Samples. The staff has
concluded that this proposed method would benefit from further
development; it will be proposed for Board adoption at a later
date.
The ARB staff is proposing amendments to the following existing
ARB Test Methods to expand their applicability to include
chloroform and polychlorinated biphenyls.
* Method 422 - Determination of Volatile Organic Compound
Emissions from Stationary Sources [new name].
* Method 428 - Determination of Polychlorinated Dibenzo-p-dioxin (PCDD),
Polychlorinated Dibenzofuran (PCDF), and
Polychlorinated Biphenyl (PCB) Emissions from Stationary
Sources [new name].
In addition, the staff is proposing amendments to the four
existing test methods listed below to update the methods, to
improve their accuracy, and to clarify certain sampling,
analytical, and quality control procedures.
* Method 202 - Certification and Test Procedures for Vapor
Recovery Systems at Gasoline Bulk Plants [new designation,
incorporated by reference in Sections 94002 and 94148, Title
17, California Code of Regulations].
* Method 203 - Certification and Test Procedures for Vapor
Recovery Systems at Gasoline Terminals [new designation,
incorporated by reference in Sections 94003 and 94149, Title
17, California Code of Regulations].
* Method 425 - Determination of Total Chromium and Hexavalent
Chromium Emissions from Stationary Sources.
* Method 501 - Determination of Size Distribution of
Particulate Matter Emissions from Stationary Sources.
The public was given an opportunity to provide written or oral
comments on the proposed methods at a workshop held on July 27,
1989. A second workshop was held on October 19, 1989, to give
the public another opportunity to comment on the proposed
methods. In addition the proposed methods were discussed at the
June 22, 1989, meeting of the California Air Pollution Control
Officer's Subcommittee on Source Test Methods for Toxic Air
Contaminants.
The staff is also proposing regulations which reference the
"Certification and Test Procedures for Vapor Recovery Systems at
Gasoline Terminals" and "Certification and Test Procedures for
Vapor Recovery Systems at Gasoline Bulk Plants" as methods for
determining compliance with district emission limitations for
bulk plants and terminals. As provided in Section 94100, Title
17, California Code of Regulations, applicable test procedures
established by districts would take precedence over the ARB
methods.
Adoption of standardized test methods promotes uniformity and
quality assurance in source testing activities by establishing a
consistent data base of air pollution information to which all
testing organizations would be contributing. The broadened data
base afforded by the standardized test methods would support and
enhance such activities as emission inventory mandated by the
"Air Toxic Hot Spots Information and Assessment Act of 1987,"
control measure development, and air quality modeling.
SUMMARY AND IMPACT OF PROPOSED BOARD ACTION
Significant issues and public comments raised at workshops have
been addressed by subsequent proposed revisions to the test
methods. The staff believes that adoption of the proposed
methods would not result in any significant adverse air quality,
environmental, or economic impacts.
ITEM NO.: 90-1-3
Adequacy of the Statewide Carbon Monoxide Ambient Air Quality
Standard: The Impact of Recent Health Effects Studies.
RECOMMENDATIONS
The Air Resources Board Staff concurs with the Department of
Health Services and recommends that the Board (1) affirm the
staff finding that the current statewide California ambient air
quality standard for carbon monoxide is adequately protective of
public health, and does not need to be revised at this time, (2)
direct staff to review this standard again in five years, or
sooner if research indicates that the existing standard may no
longer be appropriate, and (3) direct staff to monitor research
and regulatory issues relevant to the review of this standard and
to inform the Board of any significant new developments.
The California Department of Health Services (CDHS) staff
recommends that the existing California standards remain in
effect and that additional research be initiated to resolve
uncertainties.
DISCUSSION
Staff has prepared this report to update the Board on relevant
new information concerning the health effects of carbon monoxide
exposure and to provide the board with the information needed to
decide if a detailed regulatory review of the California ambient
air quality standards for carbon monoxide is required.
Health effects research indicates that the primary mechanism of
toxicity of carbon monoxide is interference with the transport of
oxygen to the cells and tissues of the body.
Research also indicates that groups potentially at risk to carbon
monoxide exposure include individuals with coronary artery
disease, congestive heart failure, obstructive lung disease,
vascular disease, anemia, the elderly, new born infants and
fetuses.
Important new health effects studies confirm that carbon monoxide
exposures can produce significant effects on the heart of
exercising patients with coronary artery disease.
