ITEM NO.: 74-7-2
Consideration of Air Quality Products, Inc. Application for
Accreditation of an Exhaust Emission Control Device for Used Cars
(1955-64 Model Years).
Approve application and adopt Resolution 74-19.
Air Quality Products, Inc. Has submitted an application for
accreditation of its 1955-65 KAR-KIT device for vehicles with
classes (b) through (f) engines. This device is similar to the
previously accredited 1966-70 KAR-KIT device, and to the General
Motors used vehicle (1955-1965) device.
The applicant cites several previous ARB staff reports and
research studies in support of this application. The applicant
has submitted emission data from a previously accredited device
(General Motors) to indicate the effectiveness of his device.
This is in accordance with amendments to the used car device test
procedures which were approved by the Board at its March 13, 1974
meeting. The staff concurs with the applicant's claim of device
similarity, and presents the basis for its recommendation in the
attached staff report.
The applicant has been asked to reconsider certain previous
statements concerning the General Motors device, in particular
"In summary, the General Motors system does not meet the
requirements of the law because of the adverse effects on the
engine operation or performance . . ." This request was made to
remove the inconsistencies between the applicant's statements and
his current application.
ITEM NO.: 74-7-3
Public Hearing Concerning Proposed Changes to Regulations
Relating to Enforcement of New Vehicle Emission Standards and
Adopt Resolution 74-22.
This report presents proposed amendments to Article 2, Subchapter
2, Chapter 3, Title 13 of the California Administrative Code
concerned with the enforcement of new vehicle emission standards
and surveillance testing. A public hearing was held on February
13, 1974 and Resolution 74-8 as amended was adopted. Held over
for reconsideration were proposed revisions to Sections 2103 and
2109(c), and additional revisions to Section 2104.
It was suggested at the hearing that the proposed revisions to
Section 2109 were more appropriate to Section 2109(b).
Consequently a notice of hearing was published to consider this
revision. The changes are intended to provide the Board with the
authority to withhold approval of the following year vehicles or
vehicles which are substantially equivalent if a manufacturer
does not take necessary corrective action on new vehicles as
required by applicable sections of Article 2, Subchapter 2,
Chapter 3 of Title 13.
The staff proposes that Section 2109 be amended as presented in
Resolution 74-22. This amendment does not vary substantially
from the published hearing notice. Instead the intent of these
sections is accomplished and the section is simplified by
combining the three subdivisions (Sections 2109 a, b, and c) into
subdivisions 2109 a and b. Further changes to Section 2103 and
2104 are not recommended. Adoption of these changes necessitates
amendment of Section 2108.
ITEM NO.: 74-7-4
Public Hearing to Certify Emergency Regulations of NOx Retrofit
Device Installation Schedule.
Adopt Resolution 74-20.
On December 19, 1973 the Board adopted Resolution 73-27G thereby
initiating emergency regulations amending Section 2008, Title 13
of the California Administrative Code. This emergency action
based on the energy crisis altered the schedule for installing
oxides of nitrogen (NOx) devices.
The then concurrent transfer of ownership (and also initial and
out-of-state registration) schedule was retained for the counties
within the Bay Area, San Diego and South Coastal Air Basins, but
the expanded transfer of ownership phase (and also initial and
out-of-state registration) for statewide implementation was
deferred from January 1, 1974 to April 1, 1974. The license
plate phase was deferred one full year until January 1, 1975.
This regulation was adopted without a public hearing. Section
11422.1 of the Government Code allows an emergency finding to
remain in effect for only 120 days. Within this time period the
finding must be certified or it reverts to the prior regulation.
Adoption of Resolution 74-20 would affirm the previous action of

ITEM NO.: 74-7-6
Summary of Manufacturers' Assembly-Line Reports for Second
Quarter - 1974 Model Year (October 1, 1973-December 31, 1973).
Refer procedural deficiencies to the Enforcement Committee.
The staff has reviewed the reports submitted by vehicle
manufacturers concerning the 1974 model-year second quarter
production (October 1, 1973-December 31, 1973). Tables I, II and
IIA of the attached staff report show those manufacturers that
did not quality audit test a 2% sample of quarterly production
vehicles and/or had more than 10% of the quality audit sample
exceed the approval standard for a given compound. Steady state
inspection control limits are given in Table III for HC and CO.
The average exhaust emissions for the first quarter (July 1,
1973-September 30, 1973) and second quarter quality audit (CVS-1
test) are tabulated in Table IV by engine family. Letters have
been sent to those manufacturers whose reports indicated
ITEM NO.: 74-7-7
Fourth Quarterly Report on the Efforts and Progress of Vehicle
Manufacturers in Meeting the 1975 and 1976 Statutory Federal
Vehicle Emission Standards.
Approve report for submission to the Legislature.
In accordance with provisions of Section 39158 of the California
Health and Safety Code, nineteen motor vehicle manufacturers
submitted fourth quarterly reports outlining the efforts and
progress made in meeting the Statutory Federal Exhaust Emission
Standards for the 1975 and 1976 model years. The majority
indicated that the catalytic approach is most promising. The
durability of the catalyst and degradation of emission control
were cited problems.
The non-catalytic approach includes use of the thermal reactor,
the rotary engine with thermal reactor, diesel engines, and the
stratified charge engine. Total engine system improvements are
mentioned with the emphasis on refinements in fuel/air mixture
ITEM NO.: 74-7-8
Surveillance Testing of Exhaust Emissions from In-use Light Duty
None. This is an information item.
The report presents results of mor than 20,000 tests on 1966-1974
model-year cars with factory installed exhaust emission control
systems. Emissions are tabulated for the last three model years
and emissions vs. Mileage are plotted for the 1966-1973 model
years. In general, these data show a reduction in emissions from
each model year.
Exhaust emission levels of vehicles equipped with accredited NOx
retrofit systems are discussed. Sixty eight vehicles of the
1966-1970 model years equipped with NOx retrofit control systems
were tested and yielded lower emissions than a comparable group
without the systems.
The report further presents emission levels obtained from 187
cards of the 9155 through 1965 model years equipped with retrofit
systems, and compares their emissions to 842 recently tested
equipped vehicles of the same age group. The data show that the
retrofitted cards which have received the required Certificate of
Compliance have lower emissions than unequipped vehicles.
