ITEM NO.: 73-8-2a
Staff report on comparative effects of NOx retrofit devices.
RECOMMENDATION
Information item only.
SUMMARY
As requested by the Board, this report presents a staff
evaluation of the effects of seven NOx retrofit devices. The
report discusses NOx emissions, exhaust gas temperature, coolant
overheating, and fuel consumption.
ITEM NO.: 73-8-2b
Report of Emissions and control Committee on the Applications of
Contignitron and Carco for Accreditation of their NOx Retrofit
Control Devices.
RECOMMENDATION
The two devices be conditionally accredited.
SUMMARY
Report of findings from a review of the applications of the
Contignitron and Carco using criteria applied to the four NOx
devices previously accredited.
ITEM NO.: 73-8-2c1
Contignitron Company's Application for Accreditation of an NOx
Control Device for 1966-70 Model Year Vehicles.
RECOMMENDATION
Deny Accreditation.
SUMMARY
At its March 21, 1973 meeting, the Board considered Contignitron
Company's application for accreditation of its device for NOx
exhaust emission control for 1966 through 1970 model year
vehicles in engine size classes a, c, d, e, and f. The Board
deferred action on the application and referred it to the
Emissions and Control Committee for review and recommendation.
The applicant has submitted data verifying compliance with the
oxides of nitrogen emission reduction standard of 41.6 percent.
Although the applicant has also submitted data showing compliance
with the general standards except for the adverse effects
criterion, the staff has reservations concerning his financial
responsibility, and his capability to adequately meet the
requirements for training, franchising and servicing a state-wide
program.
If it is the Board's decision to grant accreditation of
Contignitron's device, a proposed resolution is attached to the
staff report.
ITEM NO.: 73-8-2c2
Clean air Research Company, Inc. Application for Accreditation of
an NOx Control Device for 1966-1970 Model Year Vehicles.
RECOMMENDATION
Deny accreditation.
SUMMARY
At its March 21, 1973 meeting, the board considered Clean air
Research Company's application for accreditation of its device
for NOx exhaust emission control for 1966 through 1970 model year
vehicles in engine size classes b, c, d, e, and f. The Board
deferred action on the application and referred it to the
Emissions and Control Committee for review and recommendation.
The applicant has submitted data verifying compliance with the
oxides of nitrogen emission reduction standard of 41.6 percent.
Although the applicant has also submitted data showing compliance
with the general standards except for the adverse effects
criterion, the staff has reservations concerning his financial
responsibility, and his capability to adequately meet the
requirements for training, franchising and servicing a state-wide
program.
If it is the Board's decision to grant accreditation of the CARCO
device, a proposed resolution is attached to the staff report.
ITEM NO.: 73-8-3
Proposed Exemptions of Class (a) 1966-70 Model Year Vehicles from
Required NOx Controls.
RECOMMENDATION
Comment on the proposed Executive Order listing the general
vehicle exemptions.
SUMMARY
The Air Resources Board has recently accredited an NOx control
device for Class (a), 140 CID or less, vehicles. The blanket
exemption from the NOx retrofit program for these vehicles is
removed by the proposed Executive Order, G-19-2. Information was
sought from the manufacturers concerning exemptions for class (a)
vehicles for other reasons, and the information received to date
is summarized. Also included are revisions to the previous
exemption list to clarify and make more specific certain
exemption categories. The proposed changes to Executive Order G-19-1
are set forth in italics.
ITEM NO.: 73-8-5
Consideration of Proposed Exhaust Emission Standards and Test
Procedures for 1975 and Subsequent Model Gasoline Powered Motor
Vehicles under 6,001 Pounds Gross Vehicle Weight.
RECOMMENDATION
None. (A public hearing concerning these procedures will be held
at a future Board meeting.)
SUMMARY
In order to make the California approval test procedure
compatible with the Federal certification procedure for New Motor
Vehicles, the format for the California procedure is being
changed to identify the unique California requirements as stated
in the Health and Safety Code and Title 13 of the California
Administrative Code in addition to the applicable Federal
Regulations. The format contained herein makes maximum use of
the Environmental Protection Agency procedures by reference to
the applicable Federal Register Vol. 37 No. 221, dated November
15, 1972 and for subsequent revisions which may be adopted.
These procedures are applicable to exhaust emissions from new
light-duty vehicles first sold and registered in the State of
California. Where specific differences exist between the Federal
and California requirements, the California regulations are
stated. The requirements for crankcase and evaporative controls
for new vehicle approval have been pre-empted by the
Environmental Protection Agency.
ITEM NO.: 73-8-6
Proposed restriction on certification of crankcase emissions
control devices.
RECOMMENDATION
Hold a public hearing on proposed changes.
SUMMARY
Positive crankcase ventilation (PCV) valves on late model
vehicles have flow characteristics which may be critical to the
exhaust emission control system.
The proposed restriction will limit the certification of
replacement crankcase devices to 1967 and earlier vehicles.
The operative standard for post-1967 vehicles will be the
original equipment design, as is the case with other replacement
parts.
ITEM NO.: 73-8-7
Report of Emissions and Control Committee on investigation of
effect of fuel surfactant additives on emissions.
RECOMMENDATION
No immediate action. Review situation in 1974.
SUMMARY
Report of findings from two meetings with gasoline and automobile
manufacturers.
ITEM NO.: 73-8-8a
Gas Turbine Peaking Units at the Glenarm Plant of the City of
Pasadena.
RECOMMENDATION
None. This is an informational report.
SUMMARY
The attached report is submitted in response to the Board's
request at the April 4 meeting, and provides updated information
on the status of the power plant proposed for construction by the
City of Pasadena.
ITEM NO.: 73-8-8b
Research Contracts.
RECOMMENDATION
Adoption of Resolution 73-19 and 73-20.
SUMMARY
Research projects recommended by the Research Proposal Screening
Committee.
ITEM NO.: 73-8-8c
Report of Implementation Plans and Compliance Committee on review
of deficiencies noted in staff report presented to the Board at
its March 21, 1973 Meeting on "Assembly-Line Test Results for the
2nd Quarter Production of 1973 Model Year Vehicles."
RECOMMENDATION
No further action at this time.
SUMMARY
The Implementation Plans and Compliance Committee met on April
10, 1973 at the Air Resources Board Laboratory to review the
deficiencies noted in the results of the 2nd quarter reports of
assembly-line tests of 1973 model year vehicles. The committee
reviewed the letters sent to manufacturers noting these
deficiencies. Most manufacturers noted what steps they were
taking to correct these deficiencies. The staff is waiting for a
reply from these manufacturers.
Certain deficiencies noted were the results of some
misunderstanding and misinterpretation of the assembly-line test
procedures which have since been clarified by the latest
revisions. Most other deficiencies were resolved by agreements
reached with the various manufacturers.
