unclear as to responsiveness and to reject outright any bid submittal taking
material exception to the specifications herein.

Each bid submitted must be supported by the following:

1.Attachment 1 & 2, Bid Information and Price Sheets.

2.Identification/description of proposed facility locations including
documents evidencing ownership or option to buy or lease. (Reference
Specifications para. 4.1, 5.1 and 5.3.3)

the award of more

                                     V-6
<PAGE>


then one zone will be rejected. Bids must set forth the amount of money to be 
retained by the bidder from the inspection fee in each paid inspection volume 
category over each twelve month end of the contract. The state anticipates 
declining bid pricing based on incremental cost savings to the contractor 
through increased business volume. Consideration will therefore be given to 
volume in the calculation of lowest overall bid.

Calculation of lowest bid for a zone will be done using the following
weighted value formulae. The sum of the bid for each Paid Inspection Per
Twelve Months category times the multipliers indicated below:

The State will not guarantee the Contractor a minimum number of paid
inspections and the number of inspections performed will not be used as a
basis for adjusting the portion of the inspection fee retained. However, the
State does agree to enter into good faith negotiations to amend the contract
if any program changes by the State have a significant impact on the
Contractor(s) cost and/or revenue.

procedures, established in WAC 173-422 as presently written or as may be
amended shall be used by the Contractor with these exceptions:

1. The maximum opacity readings of gasoline vehicles during the test need
only be obtained if the vehicle exhaust is noticeable as the vehicle enters
the inspection lane. These vehicles will not be failed for exceeding the
opacity standards until the Contractor is notified to do so by the State.

2. Checks of the vehicle's onboard diagnostic system will be included in the
inspection of 1994 and later model gasoline vehicles. Computerized test
equipment which connects directly with the vehicle's onboard diagnostic
system must be used to collect this information. Any problem detected shall

<PAGE>


5. All gasoline vehicles under 8500 GVWR except constant four wheel drive
vehicles shall be tested using the Loaded Test sequence.Vehicles which appear
to be unsafe to test may be rejected and no fee collected. The Contractor may
use the initial idle mode procedures of the two speed test sequence prior to
the loaded mode of the loaded test sequence instead of the idle mode
following the loaded mode if the vehicle passes the initial idle mode.

6. No vehicle shall fail the inspection due to an missing or inoperative"
primary emission control component" or incorrect replacement engine until
June 1, 1995 or 24 months following the start date which ever is later.
However the results of the equipment check shall be recorded on the
inspection form provided the vehicle operator and included in the monthly
report as of the start date.

5.4.2 Emission Standards Variations
The emissions standards established in WAC 173-422 are subject to change in
the number and types of vehicle classifications and emission levels. The
Contractor should design their data handling system to be able to
accommodate, without additional cost to the State, changes of the emission
standards during the contract period and to allow the classes of vehicles for
which emission standards are set to vary up to ten.

5.4.3 Certificates of Acceptance
The Contractor is required to visually inspect the vehicle to verify to the
extent possible that the stated repairs have been made and that any emission
control equipment installed by the vehicle manufacturer or an aftermarket
replacement which is acceptable to the state of California or the U.S.
Environmental Protection Agency is installed and operative. On 1994 and newer
model gasoline vehicles this inspection shall include a check of the
vehicle's onboard diagnostic system.

6.0 PROGRAM ADMINISTRATION REQUIREMENTS

6.1 COLLECTION FEES DEPOSITS ESCROW ACCOUNT

The Contractor is accountable and responsible for the collection of all
inspection fees.

All fees collected in excess of the approved contract price are due the State
and will be deposited daily into a federally insured financial institution.
No later than Friday of each week, all fees due the State from the
Contractor, resulting from all inspections conducted through the previous
Sunday, shall be transferred to the State Treasurer's Concentration Account
via wire transfer. Details on how to process a wire transfer will be provided
to the Contractor by Ecology.

For the first six months inspection fees are collected, whenever an amount is
transferred to the State Treasurer an equal amount shall be deposited in a
joint escrow account with a bank or saving and loan institution of their
choice, provided that it is regulated by the State of  Washington. The Escrow
Agreement is to be executed on State form 05P - FL. 786,1 - 3l - 90 "ESCROW
INSTRUCTIONS AND    AGREEMENT."(See Appendix E )

The sums deposited therein shall remain in escrow for the duration of the
contract and may be withdrawn at any time by the State for failure of the
Contractor to submit residual payments on time or meet other contractual
obligations including interest at one percent per month on any balance due,
if the contractor is over thirty days late in transferring funds. In The
event of termination for breach, all funds in the account will be withdrawn
by the State to partially compensate the State for the costs of obtaining a
replacement Contractor(s) including any increase in the portion of the
inspection fee to be retained by the Contractor(s). Additionally such
withdrawal shall not limit the States' right to any other remedy provided in
the contract or by law. The Contract Administrator shall approve total
withdrawal

                                     VI-14
<PAGE>


of the account upon termination or completion of the contract if
all obligations of the Contractor both financial and otherwise have been
satisfied.

The State shall have the right to audit the Contractor's records and
recordkeeping system and procedures to substantiate that the Contractor has
properly collected and accounted for the proper amount.  The Contractor shall
be required to furnish copies of relevant reports, financial statements, and
other information which may be reasonably requested by the State in carrying
out said audits.  If as the result of an audit any discrepancies are found,
the Contractor shall be provided adequate time to respond 
to said discrepancies.

6.2 ACCOUNTABILITY FOR FORMS

Pre-numbered vehicle emission inspection forms will be furnished by Ecology
without charge.  For audit purposes, all of the forms must be accounted for
including voided and damaged forms.  The Contractor may be required to accept
shipment of up to 100,000 inspection forms per station at any one time.The
Contractor is solely responsible for the disposal or recycling of forms or
copies of forms no longer required. The Contractor may be required to
increase the amount of funds transferred to the State Treasurer by $500 for
each stolen,missing or unaccounted form not reported missing when the
shipping carton containing the forms is opened by the Contractor. The
Contractor operating procedures shall require the shipping cartons to be
opened only in the presence of at least two of Contractors staff.


6.3 CHANGES

The state may at any time direct the Contractor to commence amended
performance. In such event, the Contractor or the State may be entitled to an
equitable adjustment in the contract price to reflect the changes costs,
fixed and variable,of amended performance. The Contractor shall not however
delay implementing amended performance pending agreement on any price
adjustment.

The state shall have the right to request detailed cost and pricing data to
audit the Contractor's books and records to verify the appropriateness of any
additional compensation due the Contractor. Material changes in inspection
procedures, contract provisions,and any changes in contract pricing shall be
documented in writing by issuance of a contract change notice by the contract
administrator.


6.4 LIQUIDATED DAMAGES AND PAYMENT ADJUSTMENTS

                                    VI-15
<PAGE>


Any of the following occurrences will result in damage to the State:
(1) Failure to commence inspections on the scheduled start date.(2) Failure
to provide inspections after station open; (3) Questionable inspections; (4)
Excessive waiting times; (5) Failure to meet minimum staffing levels.  The
amount of such damages will be difficult to calculate.  Therefore, by
submitting a bid in response to this document, the Contractor agrees that, it
shall be entitled to reduced or no compensation, or pay liquidated damages,
as set forth below. It is agreed that such reduced compensation or liquidated
damages are a reasonable estimation of the actual damages to the State which
will result from the events specified, and shall not be viewed in any sense
as a penalty.

6.4.1 Failure to Meet Implementation Date
The State at any time may in writing demand adequate assurance that the
scheduled start date will be met at all inspection stations in a zone.

Should acceptable assurance not be forthcoming in a reasonable period of
time, the State may declare the contract in breach, and terminate the
contract. In such event, the Contractor shall remain liable to the State for
any damages it incurs as a result of such breach. Alternately the State may
elect to require the Contractor to pay liquidated damages to the State in the
amount of $1,000 for each working day after the scheduled start date for each
station for which it has not been notified in writing is ready to provide
inspection services pending satisfactory completion of acceptance testing.

The Contractor shall not however be required to pay liquidated damages for
delays beyond their reasonable control that are attributable solely to
extraordinary delays in obtaining local government approvals that were
unforeseen/unavoidable by the Contractor. In the event the Contractor
provides written notice and explanation of such delay and the State
subsequently deems the Contractor is due relief from liquidated damages an
extension of the inspection program scheduled start date will be granted
equal to the actual number of days attributable to the local government
delay. Such relief/extension will not be granted for normal time frames of
local jurisdictions for routine processing and approvals. An extension may
also be granted for any delay by the State in the award of contract(s) beyond
30 days from date of bid opening. Contractor(s) shall not be provided lost
revenue compensation for any extension period(s) granted.

The Contractor is required to provide monthly progress reports and immediate
written notice if the scheduled start date will not be met and submit a date
by which the Contractor will be ready to conduct inspections at all of its
inspections stations in a zone. 

                                     VI-16
<PAGE>


Once the Contractor notifies the State the scheduled start date will be 
missed, or when the State has reason to believe the scheduled start date may 
be missed,the State reserves the right to establish a new start date for any 
zone until after the satisfactory completion of the acceptance testing of all 
the Contractors stations in that zone. The Contractor agrees not to hold the 
State liable for any revenue lost because of the new start dates.

6.4.2 Failure to Provide Inspections after Inspection Station 
Opening:
After the inspection station is open to the public, the Contractor shall pay
liquidated damages at $125 for each whole hour the inspection station could
not provide inspections of gasoline powered vehicles during the required
operating hours.

6.4.3 Incorrect or Questionable Inspections
It is the Contractor's responsibility to correct any incorrect inspection
report.  If an incorrect inspection report results in an additional
inspection being performed, no additional payment will be collected from the
vehicle operator.

The Contractor will adjust the next weekly transfer of funds to the State
Treasurer by the following amounts when Ecology notifies the Contract in
writing that questionable inspections have been performed.

1.Analyzer Audit Failure:If Ecology audits determine that an analyzer exceeds
the tolerances for accuracy, drift,repeatability, response time, flow
restriction, or interference, all inspections performed since the last
Ecology audit or verified multipoint calibration (whichever is most recent)
will be considered questionable.

The Contractor shall pay liquidated damages to the State in the amount of
$250.00 for each Ecology analyzer audit failure.

2.Invalid Lanes: Payment will not be allowed for inspections performed at an
invalid lane. An invalid lane is a inspection location that at the time of
inspection: 1) Has not been formally accepted by Ecology during contract
acceptance testing; 2) Has been ordered closed in writing by an Ecology
representative for miscalibration or malfunction; 3) Has not undergone the
calibration requirements specified in WAC 173-422.

3.Incorrect Inspection Procedure: If the inspection was not performed
according to WAC 173-422 payment will not be allowed.

6.4.4 Excessive Waiting Time:
Waiting time is a measure of the Contractor's ability to serve the public. 
The average waiting time shall not exceed 15 minutes

                                    VI-17
<PAGE>


whether vehicles are the inspection station or on the public street.  The 
Contractor shall be considered in violation of the contract whenever the 
average waiting time exceeded 15 minutes, or if the line of waiting vehicles 
extend onto the public street for more than 10 minutes, unless the Contractor 
can document all lanes were operational and fully staffed during the 30 
minute data collection period.

The payment to the Contractor for inspections conducted during each violation
of the 15 minute waiting time standard will be prorated using the utilization
factor determined by Ecology for that 30 minute data collection period.  (See
example calculations, Appendix F )

The Contractor will adjust the next weekly transfer of funds to the State
taking into account notice of violations and the prorated payments. These
payment adjustments apply only to waiting time violations of which any of the
Contractor personnel at the inspection station are notified in writing by an
Ecology representative that day.

6.4.5 Minimum Staffing Level:
During certain times and days of the month demand for inspections will be
much than at other times.  Historically there has been increased demand for
inspections during the last week of the month.  To ensure prompt service to
the public, the State may require that each inspection lane at an inspection
station be operational and individually staffed during any period. Each
period shall not be less than four hours and the total of these periods will
not exceed 48 hours at an inspection station in any month.

Thirty days advance written notice of required full staff periods will be
provided by the State to the Contractor.  Note: The office is required to be
staffed at all times, whether a required full staff period or not.  To the
extent possible, maintenance should not be scheduled during full staffing
periods.

The payment to the Contractor for inspections conducted during a required
full staff period, will be prorated (on the basis that the sum of all lanes
is equal to 1.00) if at any time during this period less than full staffing
is detected in any lane or the office.  Not staffing the office will be
considered a violation at any time equivalent to not staffing a lane during a
required full staff period.  If less than full staffing is detected, it will
be presumed to have existed since the station was required to be fully
staffed, or the end of the last observation by an Ecology representative,
whichever is later.  If the Contractor can demonstrate personnel to
individually staff each lane and the office were at the station and
inspections were being conducted

                                    VI-18
<PAGE>


in all lanes during a period in question, then the required staffing 
requirements will be considered met for that period.

The Contractor will adjust the next transfer of funds to the State Treasurer
taking into account the notice of violations and the prorated payments.These
payment adjustments apply only to time periods of which any of the Contractor
personnel at the inspection station are notified in writing by an Ecology
representative of a staffing violation.

6.5 CONFLICT OF INTEREST
The successful bidder shall submit to the Contract Administrator a signed

    RCW 70.120.150  VEHICLE EMISSION STANDARDS--DESIGNATION OF NONCOMPLIANCE
AREAS AND EMISSION CONTRIBUTING AREAS. (EFFECTIVE UNTIL JANUARY 1 1993.) The
director:
    (1) Shall adopt motor vehicle emission standards to ensure that no less
than seventy percent of the vehicles tested comply with the standards.
    (2) Shall designate a geographic area as being a "noncompliance area"
for motor vehicle emissions if (a) the department's analysis of the data,
recorded for a period of no less than one year, at the monitoring sites
indicates that the standard has or will probably be exceeded, and (b) the
department determines that the primary source of the contaminant being
monitored at the sites is motor vehicle emissions.
    (3) Shall reevaluate noncompliance areas if the United States
environmental protection agency modifies the relevant air quality standards,
and shall discontinue the program if compliance is indicated and if the
department determines that the area would continue to be in compliance after
the program is

                                     VI-A6
<PAGE>
discontinued. The director shall notify persons residing in
noncompliance areas of the reevaluation.
    (4) Shall analyze information regarding the motor vehicle traffic in a
noncompliance area to determine the smallest land area within whose
boundaries are present registered motor vehicles that contribute
significantly to the violation of motor vehicle-related air quality standards
in the noncompliance area. The director shall declare the area to be an
"emission contributing area."  An emission contributing area established for
a carbon monoxide or oxides of nitrogen noncompliance area must contain the
noncompliance area within its boundaries.  An emission contributing area
established for an ozone noncompliance area located in this state need not
contain the ozone noncompliance area within its boundaries if it can be
proven that vehicles registered in the area contribute significantly to
violations of the ozone air quality standard in he noncompliance area.  An
emission contributing area may be established in this state for violations of
federal air quality standards for ozone in an adjacent state if (a) the
United States environmental protection agency designates an area to be a
"nonattainment area for ozone" under the provisions of the federal Clean Air
Act (42 U.S.C. 7401 et. seq.), (b) the nonattainment area encompasses
portions of both Washington and the adjacent state, and (c) it can be proven
that vehicles registered in this state contribute significantly to the
violation of the federal air quality standards for ozone in the adjacent
state's portion of the nonattainment area.
    (5) Shall designate areas as being noncompliance areas or emission
contributing areas, and shall establish the boundaries of such areas by rule.
The director may also modify boundaries. In establishing the external
boundaries of an emission contributing area, the director shall use the
boundaries established for ZIP code service areas by the United States postal
service.
    (6) May make grants to units of government in support of planning
efforts to reduce motor vehicle emissions n areas where emission control
inspections are not required.  [1989 c 240 Section 2.]

    RCW 70.120.150  VEHICLE EMISSION AND EQUIPMENT STANDARDS --DESIGNATION
OF NONCOMPLIANCE AREAS AND EMISSION CONTRIBUTING AREAS.  (EFFECTIVE JANUARY
1, 1993.)  The director:
    (1) Shall adopt motor vehicle emission and equipment standards to: 
Ensure that no less than seventy percent of the vehicles tested, comply with
the standards on the first inspection conducted, meet federal clean air act
requirements, and protect human health and the environment.
    (2) Shall adopt rules implementing the smoke opacity testing requirement
for diesel vehicles that ensure that such test is objective and repeatable
and that properly maintained engines that otherwise would meet the applicable
federal emission standards, as measured by the new engine certification test,
would not fail the smoke opacity test.
    (3) Shall designate a geographic area as being a noncompliance area' for
motor vehicle emissions if (a) the

                                     VI-A7
<PAGE>

department's analysis of emission and ambient air quality data, covering a 
period of no less than one year, indicates that the standard has or will 
probably be exceeded, and (b) the department determines that the primary 
source of the air contaminant is motor vehicle emissions.
    (4) Shall reevaluate noncompliance areas if the United States
environmental protection agency modifies the relevant air quality standards,
and shall discontinue the program if compliance is indicated and if the
department determines that the area would continue to be in compliance after
the program is discontinued. The director shall notify persons residing in
noncompliance areas of the reevaluation.
    (5) Shall analyze information regarding the motor vehicle traffic in a
noncompliance area to determine the smallest land area within whose
boundaries are present registered motor vehicles that contribute
significantly to the violation of motor vehicle-related air quality standards
in the noncompliance area. The director shall declare the area to be an
"emission contributing area." An emission contributing area established for a
carbon monoxide or oxides of nitrogen noncompliance area must contain the
noncompliance area within its boundaries. An emission contributing area
established for an ozone noncompliance area located in this state need not
contain the ozone noncompliance area within its boundaries if it can be
proven that vehicles registered in the area contribute significantly to
violations of the ozone air quality standard in the noncompliance area. An
emission contributing area may be established in this state for violations of
federal air quality standards for ozone in an adjacent state if (a) the
United States environmental protection agency designates an area to be a
"nonattainment area for ozone" under the provisions of the federal Clean Air
Act (42 U.S.C. 7401 et. seq.), and (b) it can be proven that vehicles
registered in this state contribute significantly to the violation of the
federal air quality standards for ozone in the adjacent state's nonattainment
area.
    (6) Shall, after consultation with the appropriate local government
entities, designate areas as being noncompliance areas or emission
contributing areas, and shall establish the boundaries of such areas by rule.
The director may also modify boundaries. In establishing the external
boundaries of an emission contributing area, the director shall use the
boundaries established for ZIP code service areas by the United States postal
service.
    (7) May make grants to units of government in support of planning
efforts to reduce motor vehicle emissions. [1991 c 199 Section 207; 1989 c

shall review annually the air quality and forecasted air quality of each area
in the state designated as a noncompliance area for motor vehicle emissions.

                                     VI-A8
<PAGE>
    (2) An area shall no longer be designated as a noncompliance area if the
director determines that:
    (a) Air quality standards for contaminants derived from motor vehicle
emissions are no longer being violated in the noncompliance area; and
    (b) The standards would not be violated if the emission inspection
system in the emission contributing area was discontinued and the
requirements of RCW 46.16-.015 no longer applied. [1989 c 240 Section 3.]

    RCW 70.120.170  MOTOR VEHICLE INSPECTIONS
REQUIRED--FEES--RESULTS--CERTIFICATE OF COMPLIANCE.  (EFFECTIVE UNTIL JANUARY
1, 1993.) (1) The department shall administer a system for biennial
inspection of emissions of all motor vehicles registered within the
boundaries of each emission contributing area.  Persons residing within the
boundaries of an emission contributing area shall register their motor
vehicle within that area, unless business reasons require registration
outside the area. Requests for exemption from inspection for business reasons
shall be reviewed and approved by the director.
    (2) The director shall:
    (a) Adopt procedures for conducting emission tests for motor vehicles.

compensation repairs on any vehicles.  No public body may establish or
operate contracted inspection stations.  Any contracts must be let in
accordance with the procedures established for competitive bids in chapter
43.19 RCW.
    (3) Subsection (2)(c) of this section does not apply to volunteer motor
vehicle inspections under RCW 70.120.020(1)(a) if the inspections are
conducted for the following purposes:
    (a) Auditing;
    (b) Contractor evaluation;
    (c) Collection of data for establishing calibration and performance
standards; or
    (d) Public information and education.
    (4) (a) The director shall establish by rule the fee to be charged for
emission inspections.  The inspection fee shall be a standard fee applicable
state-wide or throughout an emission contributing area and shall be no
greater than eighteen dollars. Surplus moneys collected from fees over the
amount due the contractor shall be paid to the state and deposited in the
general fund.  Fees shall he set at the minimum whole dollar amount required
to (i) compensate the contractor, and (ii) offset

                                     VI-A9
<PAGE>

the general fund appropriation to the department to cover the administrative 
costs of the motor vehicle emission inspection program.
    (b) Before each inspection, a person whose motor vehicle is to be
inspected shall pay to the inspection station the fee established under this
section. The person whose motor vehicle is inspected shall receive the
results of the inspection test.  If the inspected vehicles emissions comply
with the standards established by the director, the person shall receive a
dated certificate of compliance.  If the inspected vehicle's emissions do not

INSPECTIONS--FEES--CERTIFICATE OF COMPLIANCE--STATE AND LOCAL AGENCY
VEHICLES.  (EFFECTIVE JANUARY 1, 1993.) (1) The department shall administer a
system for emission inspections of all motor vehicles registered within the
boundaries of each emission contributing area.  Under such system a motor
vehicle shall be inspected biennially except where an annual program would be
required to meet federal law and prevent federal sanctions. In addition,
motor vehicles shall be inspected at each change of registered owner of a
licensed vehicle.
    (2) The director shall:
    (a) Adopt procedures for conducting emission inspections of motor
vehicles. The inspections may include idle and high revolution per minute
emission tests. The emission test for diesel vehicles shall consist solely of
a smoke opacity test.
    (b) Adopt criteria for calibrating emission testing equipment.
Electronic equipment used to test for emissions standards provided for in
this chapter shall be properly calibrated. The department shall examine
frequently the calibration of the emission testing equipment used at the
stations.
    (c) Authorize, through contracts, the establishment and operation of
inspection stations for conducting vehicle emission inspections authorized in
this chapter. No person contracted to inspect motor vehicles may perform for
compensation repairs on any vehicles. No public body may establish or operate
contracted inspection stations. Any contracts must be let in accordance with
the procedures established for competitive bids in chapter 43.19 RCW.
    (3) Subsection (2)(c) of this section does not apply to volunteer motor
vehicle inspections under RCW 70.120.020(1) if the inspections are conducted
for the following purposes:
    (a) Auditing;
    (b) Contractor evaluation;

                                     VI-A10

    (c) Collection of data for establishing calibration and performance
standards; or
    (d) Public information and education.
    (4)(a) The director shall establish by rule the fee to be charged for
emission inspections. The inspection fee shall be a standard fee applicable
state-wide or throughout an emission contributing area and shall be no
greater than eighteen dollars. Surplus moneys collected from fees over the
amount due the contractor shall be paid to the state and deposited in the
general fund. Fees shall be set at the minimum whole dollar amount required
to (i) compensate the contractor or inspection facility owner, and (ii)
offset the general fund appropriation to the department to cover the
administrative costs of the motor vehicle emission inspection program.
    (b) Before each inspection, a person whose motor vehicle is to be
inspected shall pay to the inspection station the fee established under this
section. The person whose motor vehicle is inspected shall receive the
results of the inspection. If the inspected vehicle complies with the
standards established by the director, the person shall receive a dated
certificate of compliance. If the inspected vehicle does not comply with
those standards, one reinspection of the vehicle shall be afforded without
charge.
    (5) All units of local government and agencies of the state with motor
vehicles garaged or regularly operated in an emissions contributing area
shall test the emissions of those vehicles annually to ensure that the
vehicles emissions comply with the emission standards established by the
director. All state agencies outside of emission contributing areas with more
than twenty motor vehicles housed at a single facility or contiguous
facilities shall test the emissions of those vehicles annually to ensure that
the vehicles' emissions comply with standards established by the director. A
report of the results of the tests shall be submitted to the department.

     WAC 173-422-010 PURPOSE. This chapter implements the Washington Clean
Air Act. chapter 70.94 RCW, as supplemented by the motor vehicle emission
inspection provisions codified as chapter 70.120 RCW.

     Motor vehicles are the primary emitters of carbon monoxide and emit
significant quantities of hydrocarbons and oxides of nitrogen. Emission
controls required by the federal government are designed to reduce motor
vehicle related air pollution. However, the effectiveness of these controls
is substantially reduced through deterioration, maladjustment and tampering.
Motor vehicle emission inspection serves to identify high polluting vehicles
and to reduce emissions, when such can be accomplished at reasonable cost.
These rules establish the emission standards, testing procedures, and
associated activities necessary to implement a program of air pollution
prevention and control involving motor vehicle emission inspections.

     WAC 173-422-070  TEST PROCEDURES. All persons certified by, or under
contract to, the department to conduct motor vehicle emission inspections
shall use the following test procedures. Variations to the procedures
specified may be used if approved by the department after receipt of evidence
that such changes will not interfere with the validity of the test.
     (1) A two-speed (idle and 2500 rpm) test with the transmission in
neutral or park shall be used to measure vehicle exhaust emissions for carbon
monoxide, hydrocarbons, and carbon dioxide. A vehicle with an automatic
transmission may be tested in drive for the idle test if the idle rpm in
neutral or park exceeds 1200 rpm. However, the idle rpm as tested cannot
exceed 1200 rpm unless allowed to do so by the vehicle manufacturers
specifications.
     (2) The engine shall be at normal operating temperature during the
emission test with all accessories off.
     (3) Any vehicle causing an unsafe condition, such as the continuous
leaking of any fluid onto the floor, may be rejected from the inspection
site.
     (4) Vehicles shall be approximately level during the test.
     (5) Vehicles with more than one exhaust pipe shall be tested by sampling
each tail pipe and averaging the results, unless the exhaust pipes originate
from a common point in the exhaust system. Simultaneous sampling from
multiple exhaust pipes may also be used.
     (6) The following steps shall be taken to prevent excessive dilution.
The exhaust sample probe must be inserted at least ten inches into the tail
pipe. If this is not possible, an extension boot shall be used. The exhaust
emission test results shall not be recorded if the carbon dioxide
concentration does not meet or exceed five percent.
     (7) If the engine stalls during the test, the engine shall be restarted
and one additional attempt will be made to complete the test.
     (8) If a vehicle is capable of being operated with either gasoline or
gaseous fuels, the vehicle shall be tested using the fuel it is operating on
when it enters the testing facility.
     (9) If a multiple range analyzer is used, the exhaust analyzer range
shall be selected so that the standard for the vehicles being tested is
between twenty-five percent and seventy-five percent of full scale if
possible.
     (10) Before testing a 1981 and later model Ford Motor Company vehicle
with a gross vehicle weight of 8500 pounds or less, or a 1984 85 Honda
Prelude, the engine shill be turned off and then restarted.
     (11) Increase the engine speed to 2500 +300 rpm.
     (12) Insert the probe into the tailpipe. After at least thirty seconds
record the exhaust emissions averaged over the last five seconds.
     (13) Slowly reduce the engine speed to idle (less than 1200 rpm). After
at least thirty seconds or when the readings have stabilized at a level
meeting the emission standards record the exhaust emissions averaged over the
last five seconds.

PROPOSED REGULATION REVISIONS                                    April 21, 1992

    WAC 173-422-010 PURPOSE. This chapter implements the Washington Clean
Air Act, chapter 70.94 RCW, as supplemented by the motor vehicle emission
inspection provisions codified as chapter 70.120 RCW.
    Gasoline motor vehicles are the primary emitters of carbon monoxide and
emit significant quantities of hydrocarbons and oxides of nitrogen.  Diesel
motor vehicles are emitters primarily of particulates, hydrocarbons, and
oxides of nitrogen.  Emission controls required by the federal government are
designed to reduce motor vehicle related air pollution.  However, the
effectiveness of these controls is substantially reduced through
deterioration, maladjustment and tampering.  Motor vehicle emission
inspection serves to identify high polluting vehicles and vehicles with
tampered or missing emission controls and to reduce their emissions, when
such reduction can be accomplished at reasonable cost.  These rules establish
the emission standards, testing procedures, and associated activities
necessary to implement a program of air pollution prevention and control ()
resulting from motor vehicle emission inspections.

this escrow agreement is to guarantee that all provisions of the above
referenced Washington State contract are satisfactorily performed by the
Contractor. The following are the terms, conditions, and instructional for this
escrow agreement, which is the only form which will be accepted by OSP.

1.  The monies to be deposited shall be used by you to purchase certificate(s)
    of time deposit or other interest bearing securities agreed upon by you and
    the Contractor, provided they shall be in a form which shall allow you
    alone to reconvert them into money, if you are required to do so by OSP as
    provided in paragraph 5 below.

2.  When and as interest accrues and is paid, you shall collect such interest
    and forward it to the Contractor at its address designated below; unless
    with your consent, you are otherwise directed in writing by the Contractor.

3.  Other than accrued interest you are not authorized to deliver to the
    Contractor all or any part of the certificate(s) of time deposit or other
    interest-bearing securities or monies held by you pursuant to this
    agreement except in accordance with written instructions from OSP by the
    Contract Administrator assigned to the administration of the above
    referenced Washington State Contract. Compliance with such instructions
    shall relieve you of any further liability related thereto.

4.  The expiration date of the above referenced contract underlying this
    agreement is ________________. OSP shall advise you in writing of any
    change in the contract expiration data including additional contract terms
    and you will be authorized to reinvest the monies held hereunder
    accordingly.

I.  Introduction

    A draft of this document was originally developed for use by Kentucky's
Jefferson County Air Pollution Control Distract to assist in the preparation of
a Request for Proposal (RFP) for a vehicle Inspection and Maintenance (I/M)
program consisting of transient emission testing, transient purge testing and
evaporative system pressure testing. Although Kentucky is only required to
implement a basic I/M program under the terms of the current Clean Air Act, in
its particulars, the Louisville program resembles EPA's currently recommended
enhanced I/M program design.

    This document was written in RFP style, with references to "the contractor"
and "the state" as appropriate.  Some of the provisions discussed here are
tailored to the specific needs of Louisville, Kentucky and may not fit with
other states' needs.  EPA's intention is not to recommend specific RFP language,
but rather to provide information to states so that they can develop their own
RFPs and include specific details on procedures, quality control and other
essential program features.  Much of the data used in this report was based on
the best information available at the time of drafting, but states should be
aware that EPA's test programs are continuing to be refined.  EPA intends to
update estimates of fast-pass and fast-fail rates, overall failure rates, and
other test-related information.  In addition, EPA will be refining test
procedure algorithms to maximize the effectiveness of the tests. For those
states needing to move ahead with program development, however, these estimates
provide a sound basis for drafting an RFP.

II. General Requirements

    The transient dynamometer test will be the IM240 described in EPA Report
No. EPA-AA-TSS-91-1.

    The transient testing system must operate accurately and relIably during
all ambient and climatic conditions in which the facility accepts any vehicle
for testing.  In addition, the transient dynamometer facilities shall comply
with QSHA, State, and County background pollution concentration levels and noise
levels.  The contractor is also responsible for maintaining ambient background
pollution concentration levels below those required by the Quality Assurance
program.

    The contractor shall provide a safe, convenient, and comfortable waiting
area for public use during vehicle testing.

III.     Number of Transient Test Lanes

    The contractor is responsible for determining the actual number of vehicles
subject to transient testing, by model year, and making 


<PAGE>

appropriate assumptions for the numbers of reset and fast-pass vehicles, as a
prerequisite to designing a sufficient number of transient lanes to accommodate
actual test volume.  The network shall be designed so that the average customer
wait time conforms with those specified in the RFP (i.e., no longer than a 15
minute wait to begin testing, except for the last 3 days of each month). 
Furthermore, stations should be sited so that a specified majority of motorists
are within a specified distance of a testing site (i.e., such that 80%  of all
motorists are within 5 miles of a test facility, and 95% are within 12 miles of
a test facility) .  Once in place, if the number of test lanes or facilities is
not adequate to test the number of vehicles in the model year categories
specified in the winning contract, the contractor will be responsible for
implementing corrective action, such as improving efficiency, constructing
additional test lanes, facilities, and the like.

    The state will provide an estimate of the number of vehicles by model year,
but the contractor is responsible for providing facilities to test the actual
number of vehicles in the model years specifIed.  As an additional reference on
throughput, EPA has an on-going test program in Hammond, Indiana that is
conducting transient IM24O tests, evaporative integrity (pressure) tests, and
evaporative purge tests on in-use vehicles.  Bidders may contact EPA to review
this data.  for reference purposes, EPA has provided a preliminary failure-rate
analysis of the data collected.  The failure rates are listed by model year, and
on an overall basis for selected cut points, and combinations of cutpoints. 
Table 1 provides this information for light-duty vehicles, and Table 2 covers
light-duty trucks.  At some cutpoints for the older model years (e.g., 1983 and
1984), the model-year failure rate was quite high for the sample.  It is
expected that such high model-year failure rates would drop significantly after
the first inspection cycle because the repairs needed to pass a transient I/M
test are expected to be durable (as opposed to the short-term repairs often
encountered in idle-test based programs, such as temporary idle adjustments,
etc.). Bidders should consider, however, the effect that the waiver cost limit
may have on the expected decrease in overall retest volume.  Bidders may use the
information in Tables 1 and 2 as a guide, but may not use it to absolve
themselves from the responsibility to provide sufficient facilities to meet the
terms of the RFP.

    Additionally, when using only hydrocarbon (HC) and carbon monoxide (CO)
failure criteria a preliminary EPA analysis estimated that slightly under 50% of
the 1984 and newer vehicles tested would meet a fast-pass exhaust emission
criteria of 1.1 gpm HC and 5 gpm CO by second 93 in the IM24O (i.e., Bag 1). 
The contractor should be aware, however, that a small portion of fast-pass purge
vehicles may need to be operated until second 190.

    As experience is gained on the throughput capabilities, failure rates,
fast-pass rates, and fast-fail rates, the state may elect (at no cost to itself)
to increase the model years covered, or tighten the standards to take advantage
of the improved network efficiency, thereby increasing the number of transient
tests to be conducted for a fixed number of existing transient test lanes.  If,
subsequently, the average wait time exceeds specifications, the state may elect
to readjust the model year coverage downward, with the understanding that such
coverage shall not fall below the range originally specified in the contract.

IV. Vehicle Standards

    The contractor shall make provisions to allow for a phase in of emissIon
standards, as well as potential future changes in the numerical levels of the
following standards at no cost to the state.  Potential future standards would
be limited to one set of changes per year.  Implementation of the initial
phase-in standards will be at the discretion of the state at the time of program
implementation. Implementation of intermediate phase-in standards will be
limited to once per quarter during the first year and a half of implementing
pass/fail standards on the transient test.

    1.   Exhaust Standards

    All 1984 and later model year light-duty vehicles and light-duty trucks
(EPA classes LDT1 and LDT2) exceeding the gram per mile (gpm) limits listed in
Table 3 on the IM240 transient driving cycle shall fail the exhaust portion of
the test.  The phase-in standards shall apply for at least one calendar year
from program implementation.  However, the contractor shall make provisions that
will allow the state to exercise (at no cost) alternate phase-in standards
necessary to arrive at the final standards specified with a minimum disruption
to the public.  If needed, as determined by the state, the contractor shall also
provide for phase-in and final standards for light-duty trucks with test weights
above and below a value selected by the state 

                                    -7-

<PAGE>

(e.g., LDT1 and LDT2) .  The state shall be able to implement standards below
the final standards specified (at no cost to the state); however, the contractor
is not obligated to exceed the maximum throughput of the specified final
standards if the state Implements lower standards.

    2.   Purge Standards

    Vehicles with an evaporative purge rate measuring less than one liter over
the transIent dynamometer test shall fail the evaporative purge test. 
Additionally, vehicles with a missing or obviously damaged canister shall be
failed for a malfunctioning canister.

    3.   Integrity Standards

    Vehicles which cannot maintain a pressure of 8 inches of water for 2
minutes (or equivalent as demonstrated by an acceptable alternative procedure)
shall fail the evaporative integrity test.  Additionally, vehicles shall fail
the evaporative integrity test if the canister is missing or obviously damaged,
if evaporative hoses are missing or obviously disconnected, or if the gas cap is
missing.  If it is determined that a vehicle's gas cap appeared to be
insufficiently tightened after it has failed the integrity test, the gas cap
shall be properly (not excessively) tightened, and the test shall be repeated.

<PAGE>

    4.   Retest Standards

    Standards for retest vehicles shall be the same as the initial test
standards.  Retest vehicles shall be retested against all standards (i.e.,
exhaust, purge, and integrity) regardless of the initial failure category.

    5.   Fast-Pass Standards

    The contractor shall make provisions that would allow the implementation of
fast-pass routines (at no cost to the state) to increase lane throughput. 
Before implementing any fast-pass routines that are proposed by the contractor,
the contractor shall obtain authorization from the state to implement such
proposals.  Exhaust fast-pass routines will likely be based on the level of
emissions in Bag 1 (see Section V), the level during certain modes of the
driving circle, or a combination of the two that is below a projected level. 
The contractor may also choose to store second-by-second readings from each
vehicle which, upon analysis of the data base created by these readings, might
allow a vehicle to meet a fast-pass criteria before the end of Bag 1.  Purge
fast-pass routines will likely be based on the measured purge flow exceeding the
minimum purge level by some point In the driving cycle.  Integrity fast-pass
routines will likely be based on minimum parameters developed for the integrity
test.

    At the state's discretion, the implementation of a fast-pass routine may
quickly pass all cars meeting the criteria, or may only quickly pass cars
meeting the criteria when there is a backup of vehicles waiting for a test.

    6.   Fast-Fail Standards

    The contractor shall make provisions that would allow the implementation of
fast-fail routines (at no cost to the state) to increase lane throughput. 
Before implementing any fast-fail routines that are proposed by the contractor,
the contractor shall obtain authorization from the state to implement such
proposals.  Exhaust fast-fail routines will likely be based on the level of
emissions in Bag 1, the level during certain modes of the driving cycle, or a
combination of the two exceeding a pre-selected level.  It is also likely that
any fast-fail routine will use an initial portion of the transient cycle for
vehicle preconditioning before making a fail decision on some other portion of
the cycle.  Purge fast-fail routines will likely be based on a measured purge
flow significantly below the minimum purge level by some point in the driving
cycle, or obviously disconnected purge hoses.  In the case of low purge flow, a

                                   -10-

<PAGE>


vehicle shall not be failed for purge flow until after 190 seconds of the
IM240, unless the contractor makes provisions for fast-fail test duration by
manufacturer.  Integrity fast-fail routines will likely be based upon minimum
parameters developed for the integrity test, such as failure to achieve initial
evaporative system test pressure. Obviously disconnected evaporative system
hoses, a missing canister, or a missing gas cap shall be used to place a vehicle
in the fast-failing category.

    At the state's discretion, the implementation of a fast-fail routine may
quickly fail all cars meeting the criteria, or may only quickly fail cars
meeting the criteria when there is a backup of vehicles waiting for a test.

    7.   Special Considerations

    Some vehicles may be difficult to test on the transient driving cycle or
using the purge or vapor-integrity tests. The state will develop procedures as
necessary for such vehicles utilizing equipment provided by the contractor.  The
contractor shall implement such procedures and develop any necessary software at
no cost to the state.  The contractor may propose to the state, at any time,
procedures to minimize the number cars needing specIal consideration; however,
all such special procedures shall require state approval prior to
implementation.

V.  Test Procedures

    The contractor shall develop and maintain written, up-to-date procedures
for conducting the required tests.

    1.   Vehicle Prep

      -  Prior to the dynamometer procedure, the following shall occur:

      -  All accessories shall be turned off.

      -  Vehicle Information shall be determined, so that the proper inertia
         and power absorption can be automatically selected, and so that test
         data and test status (i.e., initial, retest, etc) can be properly
         stored for the vehicle.

      -  The vehicle shall be checked for a missing gas cap.  The tightness of
         the gas cap may also be checked.  If

                                   -11-

<PAGE>

         loose, the cap shall be properly (not excessively) tightened, and the
         owner shall be informed of the air pollution impact of a loose gas
         cap, and advised that they can do their part to help clean the air by
         properly tightening the gas cap after refueling.

      -  The evaporative purge measurement system shall be pneumatically
         attached to the vehicle.

      -  The vehicle shall be checked for a missing or obviously damaged
         evaporative canister, or obviously disconnected evaporative system
         hoses.

      -  Preparation equipment for the evaporative integrity analysis system
         may also be pneumatically attached. However, the preparation equipment
         shall not interfere with the proper operation of the vehicle's
         evaporative system.

    2.   Dynamometer Procedure

         The dynamometer procedure shall Include the following events:

      -  Maneuvering the vehicle onto the dynamometer.  Note: the transient
         driving cycle shall be conducted with the hood up.

      -  Automatically restraining the vehicle.

      -  Automatically positioning the cooling system, and activating it.

      -  Sampling the background concentrations for a minimum of 15 seconds
         prior to the beginning of the transient driving cycle.

      -  Checking vehicle/dynamometer alignment, and drying wet-tires with the
         preselected load and inertia weight.

      -  Allowing the vehicle to idle with a vehicle speed of zero for a
         minimum of 10 seconds.

      -  Beginning the transient emission test driving cycle.

                                   -12-


<PAGE>

      -  Sampling the emissions over the driving cycle.

      -  Integrating the exhaust emission concentration (not voltages) over the
         specified test modes.

      -  Recording the evaporative purge results.

      -  Sampling the background concentrations at the conclusion of the
         driving cycle.

      -  Deactivating the cooling system, and automatically stowing the cooling
         system.

      -  Automatically removing vehicle restraints, and maneuvering the vehicle
         off the dynamometer.

    3.   Evaporative System Purge Test Procedures

         The purge test procedure shall consist of measuring the totalized
purge flow (in standard liters) occurring in the vehicle's evaporative system
during the transient dynamometer emission test.  The purge flow measurement
system shall be connected to the purge portion of the evaporative system in
series between the canister and the engine, preferably near the canister.

    4.   Evaporative System Integrity Test Procedures

         The evaporative system integrity analysis system shall determine the 
ability of a vehicle's evaporatIve system to maintain pressure above 9 inches 
of water for 2 minutes after being pressurized to 14 (PLUS/MINUS .5) inches 
of water.  All components and lines of the evaporative system between the 
evaporative canister and the gas cap that primarily convey or control fuel 
vapor, or separate liquid from vapor shall be checked (components conveying 
or controlling liquid fuel are not included).  Although alternative 
procedures may be used to increase throughput (subject to the contract 
equipment specifications), the existing procedure includes:

     Connecting the test equipment to the fuel tank canister hose at the
     canister end.  Although not part of the current procedure, it is
     recommended that the gas cap be checked to determine if it is secured
     properly during vehicle check-in, and if not, to properly (not excessively)
     tighten to cap.  The tightness of the cap could also be checked before the

                                    -13-


<PAGE>

    system is pressurized at the lane Integrity-checkIng station.  For
    vehicles with obviously loose caps, the owner shall be Informed of the air
    pollution Impact of a loose gas cap, and advised that they can do their
    part to help clean the air by properly tightening the gas cap after
    refueling.

    -    Pressurizing the system to 14 (+/-O.5) inches of water (without
         exceeding 26 inches of water system pressure)

    -    Closing off the pressure source, and sealing the evaporative system.

    -    Monitoring the pressure decay in the system for up to 2 minutes.

    -    Removing the gas cap after integrity is established to monitor for a
         sudden drop in system pressure.

                                   -14-


<PAGE>

    -    On failed vehicles only, if the gas cap appears loose when checking
         for fuel tank pressure, and it has not been previously checked for
         tightness, the cap shall be properly (not excessively) tightened, and
         the test shall be repeated.

    -    For vehicles that pass the repeated test after the the gas cap is
         properly tightened, the owner shall be informed of the air pollution
         impact of a loose gas cap, and advised that they can do their part to
         help clean the air by properly tightening the gas cap after refueling.

(INFO BETWEEN PAGE 10 AND 12 MISSING)

average emission index (grams second) values need to be stored.

4.  Consumer Report

    The contractor shall provide the consumer with a report clearly indicating
the pass, fall status, the test scores, and whether the test was an initial test
or a retest.  Additionally, the consumer report shall provide information on any
applicable warranty coverage, and include an inspector's signature block.  The
specific language on warranty shall conform to EPA I/M regulations and 40 CFR
Section 85 Subpart W on warranty statements for the model year of the vehicle at
the time of I/M testing.  Required changes to the warranty statement shall be at
no cost to the state.  (NOTE:  Because the Clean Air Act of 1990 changed the
period of the performance warranty and of the defect warranty for 1995 and later
vehicles, the contractor may need to make provisions to give the consumer a
different warranty statement depending on the model year of the vehicle, and
final EPA guidance.)  

    The contractor shall provide the consumer with a "retest" report that
includes all of the information in the initial test report, but is clearly
distinguishable from the initial test report.  Additionally, the retest report
shall provide information on the change in fuel economy (in an acceptable form
to the state and EPA with appropriate caveats based on state and EPA guidance)
and the pounds of emissions reduced per 10,000 miles of driving from the
required repairs.  The state may (at no cost) choose to delay printing of the
fuel economy and emission reduction information upon initial start up pending
analysis of data collected.  The state may also choose to highlight the

                                   -15-



<PAGE>

 emissions reduction with a short spirited statement on the report.

5.  Mechanic's Vehicle Report  

    Anyone seeking to repair an individual vehicle shall be able to obtain from
the contractor the vehicle's modal test values, bag values, and the
corresponding average values for passing vehicles of the same model year,
manufacturer, and engine family.  For the evaporative system tests, the
contractor shall include information on the type of failure (i.e., integrity or
purge), and for integrity tests, the reason for failure (e.g., failed to hold
pressure, missing canister, disconnected hoses, etc.).  In addition, the
contractor shall also make available in a manner similar to the modal
information, On-Board Diagnostic (OBD) codes/information, and any tampered
components/systems identified, if such information becomes part of the
inspection process.  

    The contractor shall also make available the information in the mechanic's
report to the repair industry by electronic means.  The electronic access shall
be convenient and standardized.  The contractor shall consider BAR 90 access
methods, emerging Society of Automotive Engineering (SAE) standards, AIAG/ANSI
data interchange protocols, and the repair industry's needs and equipment in
selecting a convenient and cost effective (to the repair industry) data exchange
protocol.  The contractor may propose to provide read-only access to data
provided to the state, if the access is limited to the test data (requires
review and approval by the state), if the access to system is convenient, and if
the access equipment is cost effective to the repair industry.  The contractor
shall be responsible for determining and keeping up with demand for data by
electronic means.  

6.  Service Center Feedback Report

    The contractor shall provide a monthly feedback report to each service
center that submits more than five vehicles per month for retesting.  The
feedback report shall be designed and modified as necessary to assist the repair
industry in effectively evaluatIng their progress in improving emission repairs.
Control chart analysis and input from the repair industry is highly recommended.
The following shall be included as a minimum.  

      -   Number of vehicles submitted for retest

      -   Number of vehicles submitted for retest that failed retest

                                   -17-

      -  Contribution of service center to air quality (i.e., total tons, or
         pounds, of pollution reduced from repairs to vehicles submitted for
         retest during a given reporting period).  The contribution of repairs
         to vehicles submitted for retest shall be broken out by the following
         categories, and shall include all pollutants:  

         -    All repairs  

         -    Repairs to complying vehicles  

         -    Repairs to passing vehicles  

         -    Repairs to waived vehicles  

         -    Repairs to failed vehicles  

      -  Contribution of service center to energy savings (i.e., fuel economy
         improvements or savings due to repairs on vehicles submitted for
         retest during reporting period) The contribution of repairs to
         vehicles submitted for retest shall be broken out by the following
         categories, and for each initial failure type (e.g., NOx failure
         repairs, CO failure repairs, etc.).  

         -    All repairs

7.  Calculations  

    Emissions shall be calculated in grams/mile for the composite test; Bags 1
and 2; and Modes 1 through 9.  

    The pre-test background concentrations shall be used to adjust the
    integrated exhaust concentrations as specified in 40 CFR Section 86.144-9O,
    and as specified in the "Integration" requirements included in Section
    VII(4)(C) of this document.  Pre- and post-test ambient background
    concentration levels shall be averaged to determine Quality Assurance
    background validity.  All adjusted exhaust emission concentrations shall be
    converted to mass values using the constants and equations contained in 40
    CFR Section 86.144.  The mass value shall be divided by the appropriate
    measured distance traveled to obtain grams per mile (gpm).  The composite
    test value shall be calculated to determine pass/fail status as follows:  

                                                    239

8.  Dynamometer Settings

    The contractor shall be responsible for maintaining and updating (at no
cost to the state) look-up tables (or an equivalent) for road load absorption
settings and inertia weight selections.  The updating shall include adding model
years and categories, as necessary to reflect the I/M test fleet.  EPA will
provide (likely on a yearly basis) a listing horse power values (at 50 mph)
and/or coast-down times (55 mph to 45 mph), and consolidated vehicle test
weights categorized by model year, vehicle market name (e.g., Chevrolet, Buick,
Geo, etc.), vehicle identity label (historically referred to as the car "line,"
e.g.,

    The contractor shall convert the EPA-supplied test track (i.e., actual)
road load horse power values (or coast-down times) to indicated dynamometer
power absorption settings based on the procedures specified in 40 CFR Section
86.118-78, and as specified in the dynamometer equipment specifications.  

B.  Inertia Weight Selection

    The inertia weight selections should not need any modification to be used
directly.  

C.  Default Settings

    In some cases, a vehicle may not be in the standard look-up table for power
absorption and inertia settings.  In those rare cases, and until the look-up
table is updated, the contractor may use a default setting based on the number
of cylinders in the vehicle's engine.  A record of the number of vehicles tested
with a default setting, the type of setting, and the facility shall be
maintained and available to the state.  EPA will likely provide the default
settings, which will likely be in the form of the following table.  The default
table shall be designed to be updated.

VII.  Equipment Specifications

1.   Dynamometer Specifications

     The dynamometer shall accommodate all LDT's and LDV's up to 8500 pounds
curb weight.  The dynamometer system shall incorporate automatic features
that will select the proper road load horsepower and inertia simulation based
on the vehicle parameters entered into the test system (or already in the
vehicle test record) at the time of vehicle check-in.  The contractor may
propose a non-automatic system, if the contractor also describes a Quality
Assurance method providing equivalent or better assurance of correct
selections, and equivalent or better lane throughput.

A.   Power Absorption

     Range and Absorption Curve - The range of power absorption at 50 mph
shall be 4 to at least 30 horsepower.  The speed versus horsepower absorption
curve shall follow equation  [VII-1] between 5 and 60 mph.  The absorption
shall be adjustable across the specified range at 50 mph in 0.1 horsepower
increments.  The accuracy of the power absorber shall be +/-0.25 horsepower.  

[VII-1]   F = A + { (B)  *  (velocity) }   + { (C) * (velocity)(2)


          Parasitic Losses - The selection of the power absorption for each
test shall account for parasitic losses in the dynamometer system, such as
tire losses, bearing friction, etc.  The power setting selected, in
combination with the proper inertia test weight for an individual vehicle,
shall result in a dynamometer coast-down time (with the test vehicle on the
dynamometer) that is within 1 second of the 55 mph to 45 mph coast-down time
calculated by equation [VII-2] (in English units) using the procedures in 40
CFR Section 86.118-78 (also see Quality Assurance requirements for periodic
calibration).  

[VII-2] Coast-down Time =

(0.06073) * (Inertia Weight Selected)

<PAGE>

B.   Inertia Simulation

          The dynamometer shall be equipped with mechanical inertia weights
providing test inertias of 2000 to 5500 pounds, varying by 500 pound
increments.  It is acceptable to use a base dynamometer inertia of 2000
pounds with three inertia flywheels of 500 pounds, 1000 pounds, and 2000
pounds to provide the specified test weights.  The proper inertia weight for
any test vehicle must be selectable.  The actual inertia weights/flywheels
operating during the test must be identified in the Quality Assurance
process.  Electric inertia simulation, or a combination of electric and
mechanical simulation may be used, provided that the performance of the
electrically simulated inertia complies with the specifications for
electrical Inertia simulation in EPA's "Specifications for Electric Chassis
Dynamometers," RFP No. C100081T1.  

C.   Inertia Weight Selection

          For dynamometer systems employing mechanical inertia flywheels, the
test system shall be equipped with a method, independent from the flywheel
selection system, that identifies which inertia weight flywheels are actually
rotating during the test.  For systems employing electrical inertia
simulation, an algorithm identifying the actual inertia weight curing the
test shall be used.

     D.   Rolls

          The dynamometer shall he equipped with twin coupled rolls.  Either 
8.6 inch (PLUS/MINUS 0.04%) diameter rolls or 20.0 inch (PLUS/MINUS 0.04%) 
diameter rolls may be used.  The dynamometer rolls accommodate an inside 
track width of 36 inches and an outside track width of 108 inches.  The roll 
size, surface finish, and hardness shall be such that tire slippage on the 
first acceleration of the IM24O is minimized under all weather conditions; 
that the specified accuracy of the distance measurement is maintained; and 
that tire wear and noise are minimized.  

E.             Test Distance/Vehicle Speed

          The test system shall measure the distance traveled for each phase 
or the IM240, and shall also measure the equivalent vehicle speed (i.e., roll 
speed).  The measurement of the actual roll distance for each bag shall be 
accurate to within PLUS/MINUS 0.01 mile.  The measurement of the roll speed 
shall he accurate to within PLUS/MINUS 0.1 mph.

                                   -24-

<PAGE>

F.   Vehicle Restraint

          The test system shall provIde for automatic vehicle restraints,
upon operator initiation, that do not require an
operator to 'tie-down' the test vehicle.  The restraint system shall allow
unobstructed vehicle ingress and egress, shall be capable of safely
restraining the vehicle under all operating conditions, and shall not damage
the vehicle.  Operation of the system shall also not damage I/M vehicles, and
shall not impart any adverse vertical or horizontal force.  Idler rollers may
be use in compliance with these requirements.  At the conclusion of the test,
operator initiation shall cause the restraint system to be stowed in a manner
that allows the vehicle to be quickly and safely removed from the
dynamometer.  

G.   Vehicle Cooling

          The test system shall provide for a method to prevent over heating
of the vehicle in a manner similar or equivalent to that specified in 40 CFR
Section 86.135-9O(b).  The cooling method shall direct air to the radiator of
the test vehicle (typical cooling air speed for such equipment is equivalent
to approximately 20 MPH).  Care shall be taken to avoid improper cooling of
the catalytic convertor.  Positioning of the cooling system shall be
accomplished quickly and effortlessly through automatic means.  

H.   System Calibration

          The system shall provide for the automatic computation and
recording of each dynamometer coast-down check performed (see Quality
Assurance procedures).  The clock used to check the coast-down time shall be
accurate to the nearest 0.01 seconds when totalizing 1000 seconds.  

I.   Operator Controls

          The operator shall have a control console or pendant that can be
conveniently operated from the driver's seat of the test vehicle.  The
control pendant shall allow the test vehicle to be easily and quickly
maneuvered onto and off of the dynamometer without damaging the vehicle or
the console.  The pendant shall provide for the operator to:  

     activate and deactivate the automatic vehicle restraint system

     activate and deactivate the positioning of the vehicle cooling system
     (if automatic)

                                    -25-

<PAGE>

     automatically over-ride the cooling system control

     initiate the transient driving cycle and analysis system sampling, if
     not automatic (i.e., part of the overall driving cycle)

     observe the video driver's trace

     observe and verify the test vehicle identification parameters (e.g.,
     manufacturer and model); and the selected inertia weight and the power
     absorption setting

     observe indicated horsepower, and vehicle speed

     observe test time and coast-down time (if not part of video driver's
     aide)

     activate a "test abort" control

J.   Four-Wheel Drive

          The contractor shall include as a separate cost option (which the
state may exercise) the ability to test four-wheel drive vehicles.

          Part-Time Four-Wheel Drive - In general, part-time four-wheel drive
vehicles shall be tested in the two-wheel drive mode by the normal testing
procedure.  

          Full-Time Four-Wheel Drive - The contractor shall include separate
cost options for one test lane in the I/M network capable of testing
full-time four-wheel drive vehicles, and for at least one test lane at each
facility capable of testing full-time four-wheel drive vehicles.  The method
for testing full-time four-wheel drive vehicles shall allow vehicles with
different wheel base lengths to be tested, shall allow the application of
correct vehicle loading for the IM240 driving cycle, and shall not damage the
four-wheel drive system.  At a minimum, if front and rear wheel absorbing
units are used, they shall maintain speed synchronization to the same
tolerances specified in EPA's RFP No. C1000881T1.

2.   Driver's Aid

     The driver's aid shall be a video-type driver's aid (VDA).

                                    -26-

<PAGE>

A.   Speed-Time Trace

     The speed versus time trace for the transient dynamometer test shall
conform to the IM240 driving cycle in EPA Report No. EPA-AA-TSS-91-1. 
However, provisions shall be made such that alternative driving schedules
(not to exceed four minutes in length) may be conveniently substituted at the
state's request (at no cost to the state).

B.   Shift Schedules

     EPA's standard shift schedules and procedures shall be used for the
transient driving cycle.  When testing vehicles equipped with automatic
transmissions, the inspector shall use the highest gear selectable (i.e.,
overdrive, or - when not equipped with overdrive - drive), and shall be
allowed to shift automatically.  Manual transmissions shall be shifted by the
following schedule.  Shift marks and gear selection shall be located on the
driver's trace.  Only shift marks applicable to the number of gears in the
transmission need to be used (i.e., all shift marks may appear on the trace).

3.   Constant Volume Sampler

     A Constant Volume Sampling (CVS) system of the Critical Flow Venturi
(CFV) type shall be used to collect vehicle exhaust samples.  The CVS system
and components shall generally conform to the specifications in 40 CFR
Section 86.109-90 with the following provisions.

A.   Mixing Tee

     The dilution mixing tee shall be moved to the vehicle tailpipe exit as
in Section 86.109-30(a)(2)(iv).  The contractor is responsible to insure that
the design(s) used collects all of the sample from the variety of exhaust
systems in the fleet, and does not cause static pressure variations in the
tailpipe of more than +5 inches of water (1.2 kPa).  The mixing tee shall
have a device for positively locating the tee relative to the tailpipe with
respect to distance from the tailpipe, and with respect to positioning the
exhaust stream from the tailpipe(s) in the center of the mixing tee flow
area.  The locating device, or the size of the entrance to the tee shall be
such that if a vehicle moves laterally from one extreme position on the
dynamometer to the other extreme, that mixing tee will collect all of the
exhaust sample.  The design of the mixing tee will be evaluated with back to
back testing of several vehicles over a range of adverse conditions with a
positive connection to the tailpipe (i.e., the 


                                   -28-

<PAGE>


mixing tee will be effectively moved downstream, as in typical FTP testing, 
for these qualification tests).

                                   -29-

<PAGE>

B.   Dual Exhaust

     As indicated above, the contractor is responsible to insure that the
design of the sampling system used collects all of the sample from the
variety of exhaust systems in the fleet.  This responsibility includes dual
exhaust systems. In particular, for dual exhaust systems the design used
shall insure that each leg of the sample collection system maintains equal
flow.  The contractor may be required to demonstrate (i.e., measure) that
each leg has equal flow (+ 10%) during acceptance testing.  In addition, the
CVS shall be sized such that the entrance flow velocity of each mixing tee is
sufficient to entrain all of the vehicle's exhaust. The design of the dual
exhaust system will be evaluated with back to back testing of several
vehicles over a range of adverse conditions with a positive connection to the
tailpipe (i.e., the mixing tee will be effectively moved downstream, as in
typical FTP testing, for these qualification tests).

C.   Background Sample

     The background sample probe or probes shall collect a background sample
near the entrance to the mixing tee.  At least three equally spaced locations
around the mixing tee shall be used to sample the background.

D.   Integrated Sample

     A continuous dilute sample shall be provided for integration by the
analytical instruments in a manner similar to the method for collecting bag
samples as described in Section 86.109.

E.   Bag Sample

     The CVS system shall also provide for periodically collecting vehicle
exhaust in sample bags (at least Bag 1 and Bag 2) simultaneously with the
measurement of an integrated sample to conduct Quality Assurance
verifications of the integration system.

F.   Leak Check

     A method to check the vacuum portion of the sample system for leaks
shall be provided.  The method shall be such that it can be easily performed
each time the system integrity is violated (e.g., changing a filter).

                                   -30-

<PAGE>

G.   CVS Flow Size

     The CVS system shall be sized in a manner that prevents condensation in
the dilute sample over the range of ambient conditions to be encountered
during testing.  Historically, this has dictated a 700 ACFM system over the
more traditional 350 ACFM system.  The range of ambient conditions may
dictate heated sample lines.  The contractor may also choose to use the
smaller sized CVS and heated lines to eliminate condensation and to increase
measured concentrations for better resolution (however, the 700 ACFM system
does reduce the dynamic range of the measured concentrations).  Should the
contractor choose to use heated sample lines, the sample line and components
(e.g., filters, etc.) shall be heated to a minimum of 120 F, shall be
monitored and assurance of proper operation shall be covered in the Quality
Assurance program.

H.  Sample Probe

     The sample probe shall be designed such that a continuously proportioned
volume of sample is collected for analysis.  The system shall have a method
for determining if the sample collection system has deteriorated or
malfunctioned such that a proportional sample is not being collected.  A
simple manometer to measure pressure drop across the probe has been used for
this function.

I.   CVS Compressor

     The CVS compressor unit shall be designed to maintain choke flow in the
main CVS venturi with an adequate margin, while minimizing down time and
maintenance.

J.   Materials

     All materials in contact with exhaust gas shall be unaffected by and
shall not affect the sample (i.e., the materials shall not react with the
sample, and neither shall they taint the sample as a result of outgassing). 
Acceptable materials include stainless steel, teflon, and Tedlar.-Registered
Trademark-

4.   Emission Analysis System

     Upon operator initiation, the emission analysis system shall
automatically sample, integrate, and record the specified emission values for
HC, CO, CO(2), and NOx.  Such initiation may occur automatically upon
initiation of the transient cycle, and a



                                   -31-

<PAGE>

quality control check has been made to insure that the vehicle is in the 
proper window to begin the transient test.

                                    -32-

<PAGE>

     The emission analysis system shall automatically determine the pass/fail
status, and print a consumer report.

A.   Analytical Instruments

     The analytical instruments shall comply with the methods of detection
and the specifications listed below.  The instrument ranges specified are
based on a 700 ACFM CVS.  Use of a different size CVS shall require adjusted
ranges with appropriate documentation.  Bidders may propose alternative
detection methods (e.g., FTIR - Fourier Transform Infrared) provided
sufficient engineering information and documentation is provided that will
allow an evaluation of the ability of the alternative method to meet the
overall accuracy, analytical performance, and integration requirements.  The
bidder may provide a separate cost proposal as an option for the case of
alternative detection methods.

     General Requirements - Performance of the analytical instruments with
respect to accuracy and precision, drift, interferences, noise, etc. shall be
similar to instruments used for testing under 40 CFR Section 86 Subparts B,
D, and N.  In particular, the analytical instruments are required to operate
within the stated environment, and meet or exceed the Quality Assurance
requirements throughout the lifetime of the contract.

     Total Hydrocarbon Analysis - Total hydrocarbon analysis shall be
determined by a flame ionization detector (FID).  The analyzer calibration
curve shall cover the range of 2 ppmC to 2,000 ppmC.  The calibration curve
must comply with the Quality Assurance specifications for calibration curve
generation.

     Carbon Monoxide Analysis - CO analysis shall be determined by
Non-Dispersive Infrared (NDIR) .  The CO analysis shall cover the range of 10
ppm to 10,000 ppm (1%). In order to meet the calibration curve requirements,
two CO analyzer may be required - one from 0 to 1000 or 2000 ppm, and one
from 0 to 1% CO.  The calibration curve requirements and the Quality
Assurance specifications apply to both analyzers.

     Carbon Dioxide Analysis - CO2 analysis shall be determined by
Non-Dispersive Infrared (NDIR) .  The CO analysis shall cover the range of
200 ppm to 40,000 ppm (4%) The calibration curve must comply with the Quality
Assurance specifications for calibration curve generation.

     Oxides of Nitrogen Analysis - NOx analysis shall be determined by
chemiluminescence (CL).  The NOx measurement shall


                                   -33-

<PAGE>

be the sum of nitrogen oxide (NO) and nitrogen dioxide (NO2).  The NOx 
analysis shall cover the range of 1 ppm to 500 ppm.  The calibration curve 
must comply with the Quality Assurance specifications for calibration curve 
generation.

B.   System Response Requirements

     The governing requirement for system response is the ability of the
integration system to measure vehicle emissions to within +5% of that
measured from a bag sample simultaneously collected over the same integration
period, on both clean and dirty vehicles.  Historically, continuously
integrated emission analyzers have been required to have a response time of
1.5 seconds or less to 90% of a step change, where a step change was 60% of
full scale or better.  System response times between a step change at the
probe and reading 90% of the change have generally been less than 4 - 10
seconds.  Systems proposed that exceed these historical values shall provide
an engineering explanation as to why the slower system response of the
integrated system will compare to the bag reading within the specified 5%.

C.   Integration Requirements

     The analyzer voltage responses shall be sampled at 5 Hertz, and the 5
Hertz voltage levels shall be averaged over 1 second intervals.  The
one-second average voltage levels shall be converted to concentrations by the
analyzer calibration curves.  The pre-test background concentration (as
calculated using methods established in Section 86.144) shall be subtracted
from the measured concentrations (also as specified in Section 86.144).  The
corrected concentrations shall be integrated over the specified bag or mode
interval.  The grams of emissions per bag or mode shall be determined using
the specified equations to combine the integrated concentrations (over the
specified bag or mode interval) with the CVS flow integrated over the same
interval.

     If multiple analyzers are used for any constituent (e.g., CO), the
integration system shall simultaneously integrate both analyzers.  The
integrated values for the lower range analyzer shall be used for the official
values, unless the emissions exceed the low range scale by a cumulative
amount of 5 seconds (the cumulative amount shall be a variable that can be
changed as experience dictates). If the duration of the emission
concentrations exceed the cumulative time value, only values from the higher
range analyzer shall be used for computing official values. Additionally,
background concentration levels shall be read by both analyzers, and the
background reading used shall be


                                   -34-

<PAGE>


the measurement made by the analyzer used to determine the official 
integrated test values (as specified above).

<PAGE>

D.   System Design

     Materials - All materials in contact with exhaust gas shall be
unaffected by and shall not affect the sample (i.e., the materials shall not
react with the sample, and neither shall they taint the sample as a result of
outgassing) Acceptable materials include stainless steel, teflon, and
Tedlar.-Registered Trademark-

     Bag Ports - All analysis systems shall have provisions for reading a
small volume sample bag, such as daily cross check bags, or integrator
checking bags.  A portable pump for sampling such bags is permitted.

     System Filters - The sample system shall have an easily replaceable
filter element to prevent particulate matter from reducing the reliability of
the analytical system.  The filter element shall provide for reliable sealing
after filter element changes.  If the sample line is heated, the filter
system shall also be heated.

E.   Gases

     Calibration Gases - Gases used to generate and check calibration curves
shall be traceable to NIST Standard Reference Materials (SRM) or CertifIed
Reference Materials (CRM) to within 1% by "Gas Comparison" methods.

     Span Gases - Gases used to for up-scale span adjustment, cross-check
bags, or checks, and for mid-scale span checks shall be traceable to NIST SRM
or CRM to within at least 2% by Gas Comparison methods.

     Zero Gases - The impurities in zero grade gases shall be known, and
shall not exceed 1 ppmC, 2 ppm CO, 400 ppm CO(2), and 0.3 ppm nitric oxide. 
Zero grade air shall be used for the FID zero gas.  Zero grade nitrogen shall
be used for CO, CO(2), and NOx zero gas.

     FID Fuel - The fuel for the FID shall consist of a mixture of 40% (+/-2%)
hydrogen, and the balance nitrogen.  The FID oxidizer shall be zero grade
air, which can consist of artificial air containing 18 to 21 mole percent of
oxygen.

5.  Evaporative Purge Analysis System

                                   -36-

<PAGE>
 
     The evaporative purge analysis system shall measure the instantaneous
purge flow (in standard liters/minute) during the transient dynameter cycle,
and shall compute the totalized flow (in standard liters) over the cycle. 
The purge flow measurement system shall be connected to the purge portion of
the evaporative system in series between the canister and the engine,
preferably near the canister.  The purge flow meter (and/or system) shall
comply with the following requirements.

-    Flow Rate           0 to 50 liters/minute

-    Totalized Flow      0 to 200 liters

-    Response Time       1 second to 90% of step change

-    Accuracy            1% of full scale (rate and total)

-    Calibration Gas     Air

     The process for monitoring the vehicle purge flow, entering it into the
data base, and making a pass/fail decision shall be automatic, and not
require operator intervention.  The test sequence shall be automatically
initiated when the transient driving cycle test is initiated. The only
operator intervention allowed includes identifying the vehicle, and
pneumatically connecting or disconnecting the test equipment to the vehicle
and, if necessary, activating an abort sequence.

     The system shall have sufficient adapters to connect in a leak-tight
manner with the variety of evaporative systems and hose deterioration
conditions in the vehicle fleet.  To the extent possible, the purge
measurement system should identify leaks at the connection to the evaporative
system.

6.   Evaporative System Integrity Analysis System

     The evaporative system integrity analysis system shall determine the
ability of a vehicle's evaporative system to maintain a system pressure above
8 inches of water for up to 2 minutes after being pressurized to 14 (+0.5)
inches of water.  All components and lines of the evaporative system between
the evaporative canister and the gas cap (including the gas cap) that
primarily convey or control fuel vapor shall be checked (components conveying
or controlling liquid fuel are not included).  Pressure gauges used for this
test shall have an accuracy of 0.3 inches of water (2% of 15) or better. 
Nitrogen (N2), or an equivalent non-toxic, non-greenhouse, inert gas


                                   -37-

<PAGE>

(other than Helium), shall be used for pressurizing the evaporative system.

                                   -38-

<PAGE>

     The process for filling the evaporative system, monitoring for
compliance, entering it into the data base, and making a pass/fail decision
shall be automatic, and not require operator intervention.  The only operator
intervention allowed includes identifying the vehicle, pneumatically
connecting or disconnecting the test equipment to the vehicle, initiating the
test sequence and, if necessary, activating an abort sequence.

     The process of filling the evaporative system shall not over-pressurize
the evaporative system.  In general, the pressure in the evaporative system
shall not exceed 26 inches of water during the filling process.

     The system shall have sufficient adapters to connect in a leak-tight
manner with the variety of evaporative systems and hose deterioration
conditions in the vehicle fleet.  To the extent possible, the integrity
system should identify leaks at the connection to the evaporative system.

     The evaporative system integrity analysis system shall be equipped with
an abort system that positively shuts off and relieves pressure to the
vehicle.  The abort system shall be capable of being activated quickly and
conveniently by the operator should the need arise.

     Bidders may propose an alternative procedure to evaluate the integrity
of the evaporative system for the purpose of increasing throughput.  Such
alternatives shall fully describe the process, and shall include engineering
rationale and calculations documenting how the alternative procedure provides
an equivalent or better evaluation of the evaporative system's integrity than
the specified two minute pressure decay method.  An alternative integrity
checking procedure may also be proposed as an optional procedure.  In that
case, the bidder shall indicate the effect that the optional procedure has on
the required number of test lanes and facilities, as well as effects on cost.

VIII.     Quality Assurance Requirements

     The contractor is required to develop, maintain, and update a written
Quality Assurance plan.  The Quality Assurance plan shall be designed and
implemented in such a manner that it will identify when the level of accurate
tests conducted in the program drops below 95% in any one reporting period. 
A test is not considered  accurate if the actual test results differ from the
true values by more than an absolute value of 10% when the true values are
above 0.6 times the standard.  No specific accuracy requirement is specified
for true values below 0.6 times


                                   -39-

<PAGE>

the standard; however, it is expected that the inherent performance of the 
analysis systems will maintain reasonable accuracy in this range.  Test 
quality not meeting this Quality assurance goal will require corrective 
action by the contractor at the contractor's expense.

     As a minimum, the contractor shall include the following Quality
Assurance procedures, or equivalent, as part of the implemented QA
procedures.  However, including the specific procedures listed, does not by
itself relieve the contractor from the responsibility to meet the overall
Quality Assurance goal stated above.

     As indicated below, there are two types of assurance procedures; those
done upon installation and on a periodic basis thereafter, and those done
during each test (Test Assurance Procedures).  For those done on a periodic
basis, the contractor shall begin with a period at least as stringent as
indicated, however, the contractor may (with concurrence of the Project
Officer) implement procedures that adjust the frequency of the periodic
checks, if based on collected data measuring the system's performance.  To
assure the overall health of the system, the contractor shall maintain
"control charts" of the performance of key parameters in the system.  When
key parameters approach control chart limits, the contractor shall closely
monitor such systems and take such actions as are necessary to prevent such
systems from exceeding control chart limits.  If any key parameter exceeds
the control chart limits, the contractor shall take corrective action to
bring the system into compliance with the accuracy and Quality Assurance
specifications.  Such control charts shall be available to the Project
Officer upon request.

     In addition to the Quality Assurance checks specified below, the
contractor is expected to develop routine maintenance procedures (e.g.,
periodically lubricate dynamometer bearings) to assure reliability of the
testing system over the life of the contract.

1.   Dynamometer

A.   Periodic

     Calibration - Once per week, the calibration of each dynamometer shall
be checked by a dynamometer coast-down procedure comparable to EPA National
Vehicle and Fuel Emission Lab (NVFEL - formerly the Motor Vehicle Emission
Lab (MVEL)) procedure TF-302A or 40 CFR Section 86.118-78.  Each prime
inertia


                                    -40-

<PAGE>

weight flywheel (i.e., base dynamometer, base plus 500 pound inertia weight 
(IW), base plus 1000 pound IW, and base plus 2000 pound IW) shall be checked 
with at least 2 horsepower settings within the normal range of the inertia 
weight.  The coast-down procedure shall use a vehicle off dyno type method 
(i.e., if a vehicle is used to motor the dynamometer to the beginning 
coast-down speed, the vehicle shall be lifted off the dynamometer rolls 
before the coast-down test begins), or equivalent.  If the difference between 
the measured coast-down time and the theoretical coast-down time is greater 
than +1 second, a flag shall be set, and corrective action shall be taken to 
bring the dynamometer into calibration.

     Roll Speed - On a daily basis, the roll speed and roll counts shall be
checked by an independent means (e.g., photo tachometer, etc).  Deviations of
greater than +0.2 mph or a comparable tolerance in roll counts shall require
corrective action.  Alternatively, a redundant roll speed transducer may be
used for comparison.  Accuracy of redundant systems shall be checked monthly.

B.   Test Assurance Procedures

     Power Absorption - For each test, the measured horsepower shall be
integrated from 55 seconds to 81 seconds (divided by 26 seconds), and
compared with the theoretical road load horsepower (for the vehicle selected)
integrated over the same portion of the cycle.  The same procedure shall be
used to integrate the horsepower between 189 seconds to 201 seconds (divided
by 12 seconds).  If the absolute difference between the theoretical
horsepower and the measured horsepower exceeds 0.5 hp, a flag shall be set
indicating an invalid test.

     The comparison to the theoretical horsepower of the vehicle selected
will be an indication of whether the correct horsepower was selected. 
Deviations between the two points and from the horsepower selected, will
provide an indication of the health of the dynamometer horsepower calibration
curve.

     Distance Traveled - The total number of dynamometer roll revolutions
during each Bag shall be measured, and used to calculate the distance
traveled.  If the absolute difference between the distance calculated from
the measured roll revolutions and the theoretical distance for the composite
test, and for each Bag, exceeds 0.02 miles, a flag shall be set and
corrective action shall be taken to bring the speed and distance measurIng
system into compliance.

                                   -41-

<PAGE>
     Inertia Weight Selection- The mass of the actual inertia weights
operating (or electrically simulated) during the test cycle shall be compared
to the Inertia weight for the vehicle under test.  If the operating weights
differ from the vehicle specification by more than 100 pounds, a flag shall
be set, and the test voided.

2.   Driver's Aid

A.   Periodic - Not applicable.

B.   Test Assurance Procedures

     Driver's Trace - All excursions in the transient driving cycle shall be
evaluated by the procedures defined in 40 CFR Section 86.115-8(b) (1) and
Section 86.115(c), except that a speed tolerance of 4 mph instead of 2 mph
shall be used. Excursions exceeding these limits shall set a flag.

3.   Constant Volume Sampler

A.   Periodic

     Flow Calibration - The CVS flow calibration shall be checked every day
by a procedure that identifies deviations in flow from the true value. 
Deviations greater than +4% shall require corrective action.  A procedure
comparable to SPA NVFEL Test Procedure No. 210 with a Critical Flow Orifice
may be used.  Alternative procedures will require engineering justification.

     Cleaning Flow Passage - The sample probe shall be checked and cleaned
(if necessary to maintain proportional ample) at least once per month.  Once
per year, the CVS venturi passages shall be checked and cleaned, if
necessary.

     Probe Flow - The indicator Identifying the presence of proportional
probe flow shall be checked on a daily basis. Lack of proportional flow shall
require corrective action.

B.   Test Assurance Procedures

     Flow Volume - The CVS flow measured by the integrator or each Bag and
each Mode shall be compared to an historically derived nominal value for each
Bag and Mode. Deviations greater than 2% shall set a flag, indicating a void
test.

4.   Analysis System

                                   -42-

<PAGE>

A.   Periodic

     Calibration Checks - Upon initial operation, calibration curves shall be
generated for each analyzer.  The calibration curve shall consider the entire
range of the analyzer as one curve.  At least 6 calibration points plus zero
shall be used in the lower portion of the range corresponding to an
approximate IM240 emission level of 0 to 2 gpm HC, 0 to 30 gpm CO, 0 to 3 gpm
NOx, and 0 to 400 gpm CO(2).  For the case where both a low range analyzer and
a high range analyzer are used (e.g., CO), the high range analyzer shall use
at least 6 calibration points plus zero in the lower portion of the high
range scale corresponding to approximately 100% of the full-scale value of
the low range analyzer.  For all analyzers, at least 6 calibration points
shall also be used in the area of the maximum nonlinearity of non-linear
instruments, or the upper one third of the linear instruments.  Between the
range defined by the emission level and the range defined by linearity, an
additional 6 calibration points shall be used. Gas dividers may be used to
obtain the intermediate points for the general range classifications
specified.  The calibration curves generated shall be a polynomial of no
greater order than 4th order, and shall fit the data within 0.5% at each
calibration point.  (For reference, see EPA NVFEL procedure No. 204A)

     For all calibration curves, curve checks, span adjustments, and span
checks, etc., the zero gas shall be considered a down-scale reference gas,
and the analyzer zero shall be set at the trace concentration value of the
specific zero gas used.

     For the emission-specified range, experience with a 700 ACFM CVS has
indicated that appropriate emission levels at the defined ranges are
approximately 0 to 100 ppmC HC, 0 to 500 ppm CO, 0 to 50 ppm NOx, and 0 to
0.7% CO(2).

     The basic curve shall be checked monthly by the same procedure used to
generate the curve, and to the same tolerances.

     On a daily basis prior to vehicle testing, the curve for each analyzer
shall be checked by adjusting the analyzer to correctly read a zero gas and
an up-scale span gas, and then by correctly reading a mid-scale span gas
within 2% of point. If the analyzer does not read the mid-scale span point
within 2%, the system shall lock out.  The up-scale span gas shall correspond
to the average emission concentration over the test equivalent to
approximately 2 gpm HC, 30 gpm CO, 3 gpm NOx, or 400 gpm CO(2).  The mid-scale
point shall be approximately one half of the up-scale point.

                                   -43-

<PAGE>


     Also on a daily basis and after the up-scale span check, each analyzer
in a given facility shall analyze a sample bag filled with a random
concentration corresponding to approximately 0.5 to 3 times the cutpoint (in
gpm) for the constituent.  The value of the random sample may be determined
by a gas blender.  The deviation in analysis from the sample bag
concentration for each analyzer shall be recorded and compared to the
historical mean and standard deviation for the analyzers at the facility and
at all facilities.  Any reading exceeding 3 sigma shall cause the analyzer to
be placed out of service.

     During the performance of the contract, the contractor may propose to
modify the calibration frequencies based on the performance of the system, a
control chart analysis, or other pertinent information.  Should performance
deteriorate as a result of the modification, the state can direct
reinstatement of the specified frequencies.

     FID Check - Upon initial operation, and after maintenance to the
detector, each Flame Ionization Detector (FID) shall be checked, and adjusted
if necessary, for proper peaking and characterization by the procedures
described in SAE Paper No. 770141.  Additionally, every month, the response
of each FID to a methane concentration of approximately 50 ppm CH(4) shall be
checked.  If the response is outside of the range of 1.10 to 1.20, corrective
action shall be taken to bring the FID response within this range. The
response shall be computed by the following formula:


                                       FID response in ppmC
       Ratio of Methane Response  =   ----------------------
                                       ppm CH(4) in Cylinder 


     Spanning Frequency - The zero and up-scale span points shall be checked
(and adjusted If necessary) at 2 hour intervals following the daily mid-scale
curve check.  f the zero or the up-scale span points drift by more than 2%
from the previous check (except for the first check of the day), a system
flag shall be set and corrective action shall be taken to bring the system
into compliance.

     During the performance of the contract, the contractor may propose to
modify the spanning frequencies based on the performance of the system, a
control chart analysis, or other pertinent information.  Should performance
deteriorate as a


                                   -44-

<PAGE>

result of the modification, the Project Officer can direct reinstatement of 
the specified frequencies.

     Spanning Limit Checks - The tolerance on the adjustment of the up-scale
span point is 0.4% of point.  A software algoritin to perform the span
adjustment and subsequent calibration curve adjustment shall be used. 
However, software up-scale span adjustments greater than +10% shall cause a
flag to be set requiring system maintenance.

     Integrator Checks - Once per week in each test lane, emissions from a
randomly selected vehicle with official test value greater than 60% of the
standard (determined retrospectively) shall be simultaneously sampled by the
normal integration method and by the bag method.  The data from each method
shall be put into a historical data base for determining normal and deviant
performance for each test lane, facility, and all facilities combined. 
Specific deviations exceeding 5% shall require corrective action.

     Interferences - CO and CO(2) analyzers shall be checked for water
interference prior to initial service, and on a yearly basis thereafter.  The
specifications and procedures used shall generally comply with either
86.122-78 or 86 .321-79.

     NOx Convertor Checks - The convertor efficiency of the NO2 to NO
convertor shall be checked on a weekly basis.  The check shall generally
conform to 86.123-78 or EPA NOEL Form 305-01.  Equivalent methods are
acceptable, but are subject to approval by the Administrator.

     NO/NOx Flow Balance - The flow balance between the NO and NOx test modes
shall be checked weekly.  The check may be combined with the NOx convertor
check as illustrated in EPA NVFEL Form 305-01.

B.  Test Assurance Procedures

     System Artifacts (Hang-up) - A comparison shall be made between the
background HC reading, the HC reading measured though the CVS sample probe,
and the zero gas before each test.  Deviations from the zero gas greater than
10 ppmC shall set a flag.

     Ambient Background - The average of the pre-test and post-test ambient
background level shall be compared to the permissible levels of 10 ppmC HC,
20 ppm CO, and 1 ppm NOx.  If the permissible levels are exceeded, the test
shall be voided,


                                    -45-

<PAGE>

and the contractor shall take corrective action to lower the ambient 
background concentration levels, including, if necessary correcting building 
ventilation.

5.   Evaporative Purge Analysis System Flow Checks

     On a daily basis, each flow meter used to measure purge flow shall be
checked with simulated purge flow (e.g., auxiliary pneumatic pump) against a
reference flow measuring device with performance specification equal to or
better than those specified for the purge meter.  The check shall include a
mid-scale rate check, and a totalized flow check between 10 to 20 liters. 
Deviations greater than +5% shall require corrective action.  On a monthly
basis, the calibration of purge meters shall be checked for proper rate and
totalized flow with three equally spaced points across the specified ranges. 
Deviations exceeding the specified accuracy shall require corrective action.

6.   Evaporative System Integrity Analysis System Check

     Relevant parameters of the evaporative system integrity     analysis
system shall be checked on a daily basis, or on a periodic basis consistent
with good engineering practice as  indicated by the various Quality Assurance
requirements.  At a minimum, systems that monitor pressure leak down shall be
checked for integrity.  If, after the canister end is capped and is
pressurized to 14 inches of water, the pressure loses more than 0.1 inches of
water over 5 minutes, corrective action shall be taken.  On a weekly basis,
pressure measurement devices shall be checked against a reference device
equal to or better than the specified performance requirements.  Deviations
exceeding the  performance specifications shall require corrective action.

7.   Overall System Performance

A.   Periodic

     Emission Levels - The contractor shall monitor the average, median, 10th
percentile and 90th percentile of the composite emissions (HC, CO, CO(2), and
NOx) measured over a defined period for each test lane.  The defined period
shall be selected and adjusted, if necessary, (and if the state concurs) to
assure that a reasonably random sample of vehicles was tested in each lane. 
Initially, the defined period shall be weekly.  Differences in the weekly
average (or defined period average) of greater than +/-10% by any one lane from
the facility-average or combined facility-average, or by any one facility
from the combined facility-average shall require an investigation to
determine

                                   -46-

<PAGE>

whether the single lane or facility has a systematic error.  Where it can be 
determined that the averages from one facility (or facilIties) are offset 
from the average of the other facilities based on the mix of vehicles tested, 
the +10% limit shall be compared to the expected offset.  If systematic 
errors are found, such errors shall be corrected.

     Pass/Fail Status - The contractor shall monitor the average number of
passing vehicles, and the average number of failing vehicles over a defined
period for each test lane. The defined period shall be selected and adjusted,
if necessary, (and if the state concurs) to assure that a reasonably random
sample of vehicles was tested In each lane. Initially, the defined period
shall be weekly.  Differences in the weekly average (or defined period
average) of greater than +15% by any one lane from the facility-average or
combined facility-average, or by any one facility from the combined
facility-average shall require an investigation to determine whether the
single lane or facility has a systematIc error.  Where it can be determined
that the averages from one facility (or facilities) are offset from he
average of the other facilities based on the mix of vehicles tested, the +15%
limit shall be compared to the expected offset.  If systematic errors are
found, such errors shall be corrected.

B.   Test Assurance Procedures

     Fuel economy - For each test, the health of the overall analysis system
shall be evaluated by checking the test vehicle's fuel economy for
reasonableness, relative to upper and lower limits for the test inertia and
horsepower selected.  For each inertia selection, the contractor shall
determine the upper fuel economy limit (with state concurrence) using the
lowest horsepower setting typically selected for the inertia weight, along
with statistical data, est experience, engineering judgement, and possibly
EPA guidance.  A similar process for the lower fuel economy limit shall be
used with the highest horsepower setting typically selected for the inertia
weight.  For test inertia selections where the range of horsepower settings
is greater than 5 horsepower, at least two sets of upper and lower fuel
economy limits shall be determined and appropriately used for the selected
test inertia.  The upper and lower limits shall be variables that can be
changed (at no cost to the state) if needed to improve the usefulness of this
Quality Assurance Check to flag questionable test results.  Flagged tests
shall require an Investigation to determine if there is an equipment problem. 
Flagged tests with fuel economy results in excess of 1.5 times the upper
limit shall require an immediate

                                    -47-

<PAGE>

shut down of the test lane to determine the cause of the out-of-limit 
condition.

8.   Control Charts

     The contractor shall prepare and use control charts of key system
parameters as necessary to determine, forecast, and maintain performance of
each test lane, each facility, and all facilities combined within the
contract specifications.  At a minimum, the contractor shall prepare and
maintain control charts for the parameters specified below.  However,
including the specific control charts listed does not by itself relieve the
contractor from the responsibility to meet the overall Quality Assurance goal
stated above.  Quality control charts shall be made available to the state
within 24 hours of a request.

A.   Control Charts for Individual Test Lanes

     In general, control charts for Individual test lanes shall Include
parameters that will allow the cause for abnormal performance of a test lane
to be pinpointed to individual systems or components.  Test lane control
charts shall include at a minimum:

-    Overall number of flags set

-    Number of specific flags set

-    Level of difference between theoretical or selected values and measured
     values for each flag parameter

-    Level of difference between theoretical and measured coast-down times

-    Level of difference between theoretical and measured CVS flow

-    Level of up-scale span change from last up-scale span (not required if
     software corrections are tracked)

-    Level of mathematical or software correction to the calibration curve as
     a result of an up-scale span change (if used)

-    Level of difference between the analyzer response to the daily
     cross-check bag, and the bag concentration

                                   -48-

<PAGE>


-    Level of difference between the integrated measurements and the bag
     measurements

-    Level of the FID CH4 response ratio

-    Level of the ambient background concentrations

-    The average, median, 10th percentile and 90th percentile of the
     composite emissions (HC, CO, CO(2), and NOx) measured over the defined
     periodIc basis

-    Average number of passing vehicles, and average number of failing
     vehicles over the defined periodic basis

B.   Control Charts for Individual Facilities

     Control charts for IndivIdual facilities shall consist of
facility-averages of the test lane control charts for each test lane at the
facility.

C.   Combined Control Charts for All Facilities

     Combined control charts for all of the facilities shall consist of an
average of the facility-average control charts for each facility.

D.   Quality Control Statement

     Every three months after commissioning, the contractor shall make a
written statement to the state on the precision and accuracy of the tests
conducted during the three month period.  The analysis supporting the
statement shall be included, and may use control charts and/or other Quality
Assurance measures as necessary.

IX.  Technical Proposal Evaluation

     For a technical proposal to be eligible for the zone of competition, it
must provide sufficient information to describe how the bidder plans to meet
each and every required specification of this RFP.  If the RFP Evaluation
Committee determines that the elements of the bid proposal (i.e., processes,
equipment, etc.) can achieve the transient testing specifications, the
technical proposal will be considered in the zone of competition.  After
determination that a technical proposal is within the zone of competition, it
will be evaluated by the following criteria.  For evaluation purposes, it is
recommended that the technical proposal follow the general


                                   -49-

<PAGE>

outline of the transient test portion of the RFP, or at least clearly 
identify what portions of the transient test requirements are being addressed.

1.   Throughput Capability

     The transient test system will be evaluated based on the ability of the
system to meet the required number of tests versus the number of test lanes
proposed, as well as the number of lanes per facility and number of
facilities.  In the case where two bids are comparable in capacity, the bid
with the potential/flexibility to Increase the number of vehicles tested will
be scored higher.

2.   Quality Assurance Program Design

     The proposed QA plan will be reviewed to evaluate the ability of the
plan to maintain accurate and reliable measurements over the lifetime of the
contract.  The bid should provide sufficient Information to allow the
Evaluation Committee to judge the bidder's commitments.  The bid should also
include an organization chart of QA functions and responsibilities.

3.   Designed-in Flexibility

     In many cases, the RFP calls for change in the specified limits,
standards, etc. within the program.  Bids will be reviewed based on the
flexibility designed-in to the transient testing program to change and
implement such parameters, as well as the inherent flexibility in the system
to accept future changes should they become necessary.

5.   Method of Testing/Equipment Selected

     The equipment and processes proposed will be evaluated relative to their
inherent accuracy capabilities, minimum operator intervention needed (e.g.,
degree of automation), and creativity used to increase throughput.

6.   Durability of Equipment/Maintenance

     The transient testing system and the equipment selected will be
evaluated on the inherent durability of the system components, and the
methods proposed to minimize downtime, and maintain accurate results over the
lifetime of the contract.

Note:

I.    This contract is subject to RCW 43.19.1905 which authorizes state
      agencies to purchase materials, supplies, services, and equipment of
      equal quantity and quality to those on state contract from non-contract
      suppliers provided that an agency notifies the Office of State
      Procurement contract administrator that the pricing is less costly for
      such goods or services than the price from the state contractor.

      If the non-contract supplier's pricing is less, the state contractor
      shall be given the opportunity to at least meet the non-contractor's
      price.  If the state contractor cannot meet the price, then the state
      shall purchase the item(s) from the non-contract supplier.  


      If a lower price can be identified on a repeated basis, the state
      reserves the right to re-negotiate the pricing structure of this
      agreement.  In the event such negotiations fail, the state reserves the
      right to delete such item(s) from the contract.  

II.   This contract is designated as "Mandatory Use" per the contract
      definitions.  If definitions are not attached to this document, they can
      be obtained by calling (360) 902-7413.

Dear Ms. Phillips:

Thank you for the successful completion of the trial Acceleration Simulation
Mode (ASM) testing in Spokane.  This letter is your authorization to deduct
$17,948.90 from the weekly payment to the state for ten weeks for the upgrade
of the Spokane Emission Check stations to conduct ASM testing.  

I greatly appreciate the effort Envirotest made to ensure that we will be
able to quickly implement ASM testing, once it becomes an official test.

Sincerely,



Joseph R. Williams
Program Manager
