       American Gas Equipment,   Inc.   of 1111 Green Island Road,   American Canyon,

California 94589 has applied for an exemption from the prohibitions in Section

27156 of the California Vehicle Code (VC) for the TESCOM high pressure natural

gas engine fuel regulator,   P/N 20—1032—2915.    The TESCOM high pressure natural

gas engine fuel regulator, P/N 20—1032—2915,     is designed for instal;ation on

1993 and older model—year passenéer cars,     light—duty trucks, medium—duty

vehicles and heavy—duty engines operating on compressed natural gas and

utilizing an Impco conversion system.

       Based on an engineering evaluation of the TESCOM high pressure natural

gas engine fuel regulator, P/N 20—1032—2915, the staff concludes that the

TESCOM high pressure natural gas engine fuel requlator, P/N 20—1032—2915, wili

not adversely affect exhaust emissions from vehicies for which an exemption is

requested.

       The staff recommends that American Gas Equipment, Inc. be granted an

exemption as requested and that Executive Order D—315 be issued.

EVALUATION OF AMERICAN GAS EQUIPMENT, INC.‘S NATURAL GAS ENGINE FUEL REGULATOR
                   FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE
       CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE
                         CALIFORNIA CODE OF REGULATIONS
I.       INTRODUCTION
        American Gas Equipment, Inc. of 1111 Green Island Road, American Canyon,

California 94589 has applied for an exemption from the prohibitions in Section

27156 of the California Vehicle Code for the TESCOM high pressure natural gas

engine fuel regulator, P/N 20—1032—2915.    The TESCOM high pressure natural gas

engine fuel regulator, P/N 20—1032—2915, is designed for installation on 1993

and older model—year passenger cars, light—duty trucks, medium—duty vehicles

and heavy—duty engines oberating on compressed natural gas and utilizing an

Impco conversion system.

        American Gas Equipment, Inc. has submitted a sample and specifications

of the device for evaluation.



II.     CONCLUSTON
        Based on an engineering evaluation of the TESCOM high pressure natural

gas engine fuel.regu1ator, P/N 20—1032—2915, the staff concludes that the

TESCOM high pressure natural gas engine fuel regulator, P/N 20—1032—2915, will

not adversely affect exhaust emissions from véhic]es for which an exemption is
requested.


III.    RECOMMENDATION
        The staff recommends that American Gas Equipment, Inc. be granted an

exemption for the TESCOM high pressure natural gas engine fuel regulator, P/N

20—1032—2915, for 1993 and older model—year passenger cars, light—duty trucks,

medium—duty vehicles and heavy—duty engines operating on compressed natural gas

and utilizing an Impco conversion system.   The staff also recommends that

Executive Order D—315 be issued.


IV.     DEVICE DESCRIPTION
        The TESCOM high pressure natural gas engine fuel regulator, P/N 20—1032—

2915, is designed for installation on 1993 and older model—year passenger cars,

light—duty trucks, medium—duty vehicles and heavy—duty engines operating on

compressed natural gas (CNG) and utilizing an Impco conversion system.     As with

the Impco high pressure regulator, the function of the TESCOM high pressure

natural gas engine fue? regulator is to reduce the CNG tank pressure to 100

psi.   The 100 psi outlet pressure is required by the Impco brand second stage

regulator.   The functional difference between the two regulators is the
TESCOM‘s ability to operate with a maximum tank pressure of 3600 psi compared
to 3000 psi of the Impco system.     .

        The regulator operates in conjunction with the OEM computer controlled

electronic port fuel injection or carburetor, and emission control systems

already certified with the stock engine.   The tune—up specifications also

remain the same.



V.      EVALUATION AND DISCUSSTON

        An engineering evaluation was conducted to evaluate the impact of the

TESCOM high pressure natural gas engine fuel regulator on emissions.     The

TESCOM high pressure natural gas engine fuel regulator functions the same as

the Impco regulator it replaces.    It reduces the pressure from 3600 psi to 100

psi.   American Gas Equipment claims the only difference between the two

regulators fs the Tescom‘s ability to withstand an increased maximum tank

pressure.


       Therefore, since the device functions the same as the Impco‘s high
bressure regd]ator, the staff concludes that the installation of the TESCOM

high pressure natural gas engine fuel regulator, P/N 20—1032—2915, will not

have an adverse effect on exhaust emissions of 1993 and older model—year

passenger cars, lTight—duty trucks, medium—duty vehicles and heavy—duty engines

operating on compressed natural gas and utilizing an Impco conversion system.

American Gas Equipment, Inc. submitted all the required information and

fulfilled the requirements for exemption.
