ITEM NO.: 74-15-2
Public Hearing Concerning Amendments to the Assembly-Line Test
Procedures for 1975 Model-Year Vehicles.
RECOMMENDATION
Adopt Resolution 74-43.
SUMMARY
This report presents proposed amendments to the "California
Assembly-Line Test Procedures for 1975 Model-Year
Gasoline-Powered Passenger Cars and Light-Duty Trucks". Two
amendments are proposed:
(1) To delete the requirements that steady state idle
hydrocarbons and carbon monoxide control limits and
individual exhaust emission concentrations for each vehicle
be displayed on the window decal, and
(2) To clarify the vehicle sample selection requirement for
quality audit vehicles to emphasize random selection.
ITEM NO.: 74-15-3
Consideration of Lindberg Ecology Corporation's Application for
Accreditation of an NOx Control Device for 1966-70.
Report to be distributed prior to Board meeting.
ITEM NO.: 74-15-4
Status Report on Dealership Surveillance.
RECOMMENDATION
Refer violations noted in Tables I-V to the Attorney General for
appropriate legal action.
SUMMARY
The Staff has been conducting surveillance of new light-duty
vehicles located on dealers' premises as part of the
assembly-line testing program. For the period of April 1 through
June 30, 1974, 711 vehicles at 45 dealerships were inspected. The Staff
and a representative of the Attorney General's office met and
reviewed the test data. Following this review, it was determined
that a number of violations had occurred. Tables I through V
summarize the violations by category, noting the vehicle
preparation and responsible party (or parties). A discussion of
alternative legal actions is also included.
Motion by Harold Sullivan:
The matter be referred back to the staff and jointly to the
Enforcement Committee for review with the Department of Motor
Vehicles and Attorney General, and hopefully, at the next meeting
it could recommend a course of action to be taken on these
matters, as well as a general policy for further action.
ITEM NO.: 74-15-5
Possibility of Controlling Emissions from Used Heavy-Duty
Vehicles.
RECOMMENDATION
Approve Report for Submission to Legislature.
SUMMARY
On September 11, 1973, the State Senate adopted Resolution 69
directing the Air Resources Board (ARB) to study the
possibilities of establishing a program to substantially reduce
the hydrocarbon (HC), carbon monoxide (CO) and oxides of nitrogen
(NOx) emissions from used motor vehicles having a gross vehicle
weight of 6,001 to 20,000 pounds, and to report to the Senate by
September 15, 1974.
The Staff has reviewed the City of New York evaluation program
for retrofitting in-use heavy-duty gasoline-fueled vehicles. The
data show an approximate 40-45% possible NOx reduction using NOx
retrofit systems. The catalytic converter investigations (for HC
and CO) indicate that a 50% reduction in HC and CO could be
expected for these vehicles.
Cost/effective studies show that it costs less to control the
same amount of contaminant by retrofitting gasoline-powered
trucks than passenger cars. Catalytic retrofitting is not
recommended until the problems of sulfates and noble metal
compounds are resolved. The NOx retrofit of heavy-duty
gasoline-powered trucks of 6,001 to 16,000 pounds gross vehicle
weight in large metropolitan areas of the State is recommended.
ITEM NO.: 74-15-6
Progress in Implementing the License Plate Phase of the NOx
Program.
RECOMMENDATION
None. Information only.
DISCUSSION
On June 27, 1974, the California Supreme Court ruled that the
Board's action of December 19, 1973 which delayed the license
plate phase of the nitrogen oxides (NOx) retrofit program
(mandatory) for energy conservation was not justified. On July
10, 1974, the Board reinstated this phase and adopted an
installation schedule commencing August 1, 1974.
Under the program, NOx retrofit devices will be required on all
1966 through 1970 model-year light-duty vehicles unless exempted
by the Board. The 11-month program is scheduled for completion
by July, 1975. Installation on subject vehicles will be
prerequisite for vehicle registration in 1976.
The Staff has initiated the necessary administrative tasks to
ensure notification of the vehicle owners and installers, and is
confident of device availability based on information from the
device manufacturers.
ITEM NO.: 74-15-7
Summary of Vehicle Emission Related Executive order Actions
Authorized by the Board from January-July, 1974.
RECOMMENDATION
None. Informational item.
SUMMARY
This report contains a summary of the vehicle emission related
Executive Order Actions authorized by the Board from January
through July, 1974.
Specifically, this includes auxiliary gasoline fuel tank
accreditations, new vehicle and engine approvals, experimental
permits, Vehicle Code Section 27166 exemptions and miscellaneous
items.
ITEM NO.: 74-15-8
Appeal by Power Genie, Inc. Of Staff Denial Regarding Exemption
from the Prohibitions Imposed by Vehicle Code Section 27156.
RECOMMENDATION
Sustain the Staff's action by denying appeal.
SUMMARY
Power Genie, Inc. Submitted an application for an exemption from
the prohibitions of Vehicle Code Section 27156 for its "Screen
Process" device. The Executive Officer upon the recommendation
of the Staff denied Power Genie's application. The Staff
recommendation was based on an opinion that adverse emission and
engine effects would be produced by the described carburetor and
distributor modifications, inadequate installation instructions
and potential problems due to the improper installation of the
device.
The Staff presents in this report a compilation of all actions
and correspondence leading up to Power Genie's appeal. These
exhibits as numbered are:
I. The Staff Report which is an evaluation of the device and
which recommends denial for the above mentioned reasons.
II. The Power Genie, Inc. application.
III. Letter of denial from the Executive Officer.
IV. Power Genie's rebuttal to the Staff Report evaluation.
V. The Staff's rebuttal to Exhibit IV.
VI. Power Genie's formal appeal to the Board.
Since none of the problem areas initially addressed in the Staff
Report were resolved by the applicant, the Staff recommends the
Board sustain the Staff's action.
ITEM NO.: 74-15-9C-1
Research Proposal No. 7-438-27 entitled "Health Effects of Ozone
Exposure in Asthmatics," submitted by the professional Staff
Association of the Rancho Los Amigos Hospital, Inc.
RECOMMENDATION
Adopt Resolution 74-45 approving research proposal No. 7-438-27
for funding not to exceed $100,000.
SUMMARY
This proposal requests support to conduct a study to document the
clinical effects of ozone (O3) exposure in asthmatics. Male
volunteers aged 21-35, with a history of asthma but otherwise in
normal health, will be recruited and exposed in environmental
chamber to 0.20, 0.30, or 0.37 ppm O3, under conditions
simulating ambient photochemical pollutant exposures -- elevated
temperature (31øC at 35% relative humidity) with intermittent
light exercise during a two-hour exposure. Twenty subjects will
be exposed at each concentration in blind studies comparing
response to O3 exposure with response to pure-air exposure, and
pure-air exposure preceded by exposure to the odor of O3.
Effects investigated will include pulmonary physiological
changes, biochemical changes, behavioral changes, subjects' own
evaluations of symptoms and impairment of activity, and clinical
evaluation of impairment by a physician.
This proposed study of ozone effects on asthmatics will generate
data of pertinence to evaluate the validity of current air
quality standards and alert levels, and to suggest the degree of
control needed to protect the health of a significant section of
the population.
