Public Hearing to Consider Adoption of Amendments to Regulations
Regarding the Procedures for Exemption of Add-on and Modified
Parts from the prohibitions of Sections 27156 and 38391 of the
California Vehicle Code.
The staff recommends that the Board adopt the proposed revisions
to the current "Criteria for the Evaluation of Add-on and
Modified Parts." The proposed revisions would allow the ARB to
focus limited ARB staff and testing resources on aftermarket
parts which are most likely to cause increases in emissions.
This would permit the staff to examine more parts which may
impact emissions, and would result in the most cost-effective use
of state resources.
ARB staff and members of the aftermarket parts industry have
worked together to develop revised regulations which streamline
the exemption process for part manufacturers while not
compromising air quality.
The proposed revisions fall into two broad categories. The first
category of parts is described as "General Criteria" parts for
which vehicle or engine emission testing may still be required.
The testing requirements have been streamlined in terms of test
procedures, and numbers and types of test vehicles. The second
category of parts is "Compliance Criteria" parts. These are
parts for which written criteria for exemption have been
developed, and require no emission testing.
In addition, new heavy-duty testing procedures are proposed in
SUMMARY OF IMPACTS
There are potential cost savings to aftermarket part
manufacturers seeking exemptions from the prohibitions of VC
27156 and VC 38391 under the revised regulations. Manufacturers
employing Compliance Criteria would have their costs reduced to a
minimum. General Criteria part manufacturers would realize a
cost benefit as a result of fewer test vehicles, and lower cost
The staff has determined that there would be a small,
unquantifiable emission benefit from the adoption of the proposed
ITEM NO.: 90-2-2
Guidance related to the Transportation Requirements of the
California Clean Air Act.
That the Board adopt Resolution #90-11 in support of the approach
and policies presented in this guidance document.
This document provides guidance on implementing the
transportation provisions in the California Clean Air Act for air
pollution control districts, as well as transportation agencies.
The guidance outlines the various requirements and recommends how
the districts and transportation agencies can address the
requirements in their development of the 1991 air quality plans.
In addition to addressing the specific requirements of the Act,
the guidance suggests a framework for integrating transportation
and air quality planning so that the two efforts are mutually
Transportation Control measures (TCMs) are required to the extent
that they are needed for an area to attain the state air quality
standards as soon as practicable. transportation provisions in
the Act are dependent upon area classification. They address
control measure development and set transportation performance
In general, nearly all of California's urban areas will be
expected to adopt reasonably available transportation control
measures, make provision to develop indirect source control
programs, and provide for public education programs in support of
reducing emissions from transportation and areawide sources.
Areas with serious air quality problems will need to adopt TCMs
to substantially reduce passenger vehicle trips and miles
traveled per trip. Severe areas will need to achieve an average
weekday commute of 1.5 or more persons per vehicle by 1999 and no
net increase in vehicle emissions after 1997.
The guidance document also includes discussion of monitoring and
The guidance includes a suggested list of reasonably available
transportation control measures. The list includes:
1) Employer based trip reduction rules
2) Trip reduction rules for other sources
3) Management of parking supply and pricing
Transportation System Improvements
1) High occupancy vehicle system plans and implementation
2) Comprehensive transit improvement programs for bus and rail
3) Development policies to strengthen transit access and reduce
auto trips for new and existing land developments
The guidance document has been discussed at meetings of the
CAPCOA Planners and the Transportation Air Quality Review Group
and was presented at a public workshop held on December 6, 1989.
In addition, staff has consulted with Caltrans on an ongoing
basis in the development of the report. Since the workshop,
staff has received considerable written comments through letters
from local air districts, transportation agencies, etc. In
general, the comments have been supportive of the approach taken
with suggestions for strengthening or clarifying specific
portions of the text. These suggestions have been addressed in
the final draft document. Staff anticipates wide distribution of
the final document to air districts, state, regional and local
transportation agencies, transit districts, cities, and counties.
ITEM NO.: 90-2-3
Public Meeting to consider a Proposed Update to List of
Substances: Toxic Air Contaminant Program.
The staff recommends that the Board approve the revisions to the
Toxic Air Contaminant Identification List as proposed in the
This report presents the latest update to the list of substances
in the Board's Toxic Air Contaminant Program. This list contains
substances identified as toxic air contaminants by the Board and
those which are candidate toxic air contaminants.
The list is prepared and used by the staff in setting priorities
for evaluating substances as toxic air contaminants. The first
list was approved by the Board in January 1984 and has been
updated each year thereafter. The proposed Toxic Air Contaminant
Identification List - January 1990, reflects changes to last
The proposed changes were developed after reviewing updated
information on substance health effects, usage, emissions, and
exposure. In consultation with DHS staff we reviewed health
effects information from the International Agency for Research on
Cancer, the U.S. Environmental Protection Agency and the National
Toxicology Program. Emissions information from the Superfund
Amendments and Reauthorization Act, Title III, Section 313, 1988
Toxic Chemical Release Inventory and toxics inventories from
selected local air pollution control districts were also
reviewed. Along with this emissions information, the staff
reviewed the 1986 Toxic Substances Control Act Inventory List
citing production volumes for listed substances within
California. Staff also conducted modeling and a review of health
effects, exposure, usage, and atmospheric chemistry information
and discussed relevant issues with the staff of the Department of
Health Services. A request for information on substances
included on the proposed January 1990 list and the substances
under consideration for addition to the list was mailed to the
public in September 1989, as part of Board staff review of
available information regarding substances. The Scientific
Review Panel on Toxic Air Contaminants was notified of the
proposed changes to the list.
SUMMARY AND IMPACTS OF PROPOSED ACTION
The following changes are proposed to the list in 1990: (1) move
methylene chloride from Category II-A to Category I as a result
of its July 1989 adoption by the Board as a toxic air
contaminant; (2) move from Category II-B to Category II-A
acetaldehyde, benzo(a)pyrene and diesel exhaust because they have
entered the air toxic contaminant identification review proess;
(3) remove the footnote on PAHs because benzo(a)pyrene and diesel
exhaust are now under review; and (4) add acrylamide, 1,1-dimethylhydrazine and hydrazine to Category II-B of the list due
to the potential for exposure in California and the potential
carcinogenicity of these compounds.
