Amendment to Regulation 1131 Low Enhanced Inspection & Maintenance Program
Amendment to Inspection & Maintenance Plan for Implementation (PFI)
On June 15, 2010 Delaware’s governor signed SB 215 as presented by the 145th Delaware General Assembly. SB 215 provides an exception to Title 21 vehicle registration requirements for vehicles being driven by Delaware Emission Education Program ("DEEP") certified emission repair technicians during drive cycle testing. SB 215 also added to Title 7 a new section 6709, Permits for operation of motor vehicles during testing. Section 6709 provides for this vehicle registration exception to be administered by DNREC through the establishment of a new permitting program.
The purpose of this action is to update 7 DE Admin. Code 1131 to establish the permitting program stipulated by SB 215. In addition, the regulations format will be updated to conform to the style requirements of the Delaware Register of Regulations which include amending the Inspection & Maintenance State Implementation Plan also known as the Plan for Implementation (PFI).
There approximately 125 certified emission repair technicians that will be impacted by this proposed amendment. The emission repair technicians were notified that the Division of Air Quality (DAQ) is amending Regulation 1131 and were invited to attend the one of three public workshops that DAQ conducted on March 28, 2011 at Del Tech's Stanton Campus - Newark, March 29, 2011 at Del Tech's Owens Campus - Georgetown and on March 31, 2011 at Del Tech's Terry Campus - Dover.
7 Delaware Code, Chapter 60
Statements and testimony may be presented either orally or in writing at a public hearing to be held on Monday, April 2, 2012 beginning at 7:00 PM in DNREC’s Richardson and Robbins Auditorium, 89 Kings Highway, Dover, DE. Interested parties may submit comments in writing to: Valerie Gray, DNREC Division of Air Quality, 655 S. Bay Road, Dover, DE 19901.

5.0 Vehicle Coverage.
5.1 Subject Vehicles
The LEIM program is based on coverage of all 1968 and later model year, light duty vehicles and 1970 and later model year light duty trucks up to 8,500 pounds GVWR (with the exception of the five most recent model years and vehicles exempted under Section 5.2). The following is the complete description of the LEIM program:
Vehicles registered or required to be registered within the emission inspection area, and fleets primarily operated within the emissions inspection area boundaries and belonging to the covered model years and vehicle classes comprise the subject vehicles, which are as follows: (See Appendix 5 (a) for DMV Out of State Renewals)
5.1.1 All vehicles titled/registered in Delaware from model year 1968 light duty vehicles and 1970 and later model year light duty trucks and whose vehicle type are subject to the applicable test schedule.
5.1.2 All subject fleet vehicles shall be inspected at an official inspection station.
5.1.3 Subject vehicles which are registered in the program area but are primarily operated in another LEIM area shall be tested, either in the area of primary operation, or in the area of registration. Alternate schedules may be established to permit convenient testing of these vehicles (e.g., vehicles belonging to students away at college should be rescheduled for testing during a visit home).
5.1.4 Vehicles which are operated on Federal installations located within an emission inspection shall be tested, regardless of whether the vehicles are registered in the emission inspection jurisdiction. This requirement applies to all employee owned or leased vehicles (including vehicles owned, leased, or operated by civilian and military personnel on Federal installations) as well as agency owned or operated vehicles, except tactical military vehicles, operated on the installation. This requirement shall not apply to visiting agency, employee, or military personnel vehicles as long as such visits do not exceed 60 calendar days per year. In areas without test fees collected in the lane, arrangements shall be made by the installation with the LEIM program for reimbursement of the costs of tests provided for agency vehicles, at the discretion of the Director. The installation manager shall provide documentation of proof of compliance to the Director. The documentation shall include a list of subject vehicles and shall be updated periodically, as determined by the Director, but no less frequently than each inspection cycle. The installation shall use one of the following methods to establish proof of compliance: Presentation of a valid certificate of compliance from the LEIM program, from any other LEIM program at least as stringent as the LEIM program described herein, or from any program deemed acceptable by the Director. Presentation of proof of vehicle registration within the geographic area covered by the LEIM program, except for any Inspection and Maintenance program whose enforcement is not through registration denial. Another method approved by the Director.
5.1.5 Vehicles powered solely by a "clean fuel" such as compressed natural gas, propane, alcohol and similar non-gasoline fuels shall be required to report for inspection to the same emission levels as gasoline powered cars until standards for clean fuel vehicles become available and are adopted by the State.
5.1.6 Vehicles able to be powered by more than one fuel, such as compressed natural gas and/or gasoline, must be tested and pass emissions standards for all fuels when such standards have become adopted by the Department.
5.2 Exemptions
The following motor vehicles are exempt from the provisions of this regulation:
5.2.1 Vehicles manufactured and registered as Kit Cars
5.2.2 Tactical military vehicles used exclusively for military field operations.
5.2.3 All motor vehicles with a manufacturer's gross vehicle weight over 8,500 pounds.
5.2.4 All motorcycles and mopeds
5.2.5 All vehicles powered solely by electricity generated from solar cells and/or stored in batteries.
5.2.6 Non-road sources, or vehicles not operated on public roads
5.2.7 Model year vehicles 1996 and older powered solely by Diesel fuel
5.3 Any exemption from inspection requirements issued to a vehicle under this Section shall not have an expiration date and shall expire only upon a change in the vehicle status for which the exemption was initially granted.
5.4 Fleet owners are required to have all non-exempted vehicles under their control inspected at an official inspection station during regular station hours.
5.5 Vehicles shall be pre-inspected prior to the emission inspection, and shall be prohibited from testing should any unsafe conditions be found. These unsafe conditions include, but are not limited to significant exhaust leaks, and significant fluid leaks. The Division and the Department shall not be responsible for major vehicle component failures during the test, of parts which were deficient or excessively worn prior to the start of the test.
5.6 New Model Year Clean Screen: Clean Screening exemptions will be determined for model years of vehicles six to eight years old that may be exempt from the two speed idle exhaust emissions test and the evaporative emissions test (except for a fuel cap pressure test) if warranted by queue conditions at the inspection lanes. Each Delaware inspection lane shall independently control clean screen activation. Clean screen mode shall occur when the inspection lane queue exceeds 60 minutes. The Lane Manager (or designee) must advise inspection personnel to activate the process. Once a queue reduction to less than 60 minutes takes place, reversion to the normal testing protocol shall occur. Wait times will be determined by queue lengths that surpass lane markers that indicate expected wait time of 60 minutes or more. The Lane Manager (or designee) is responsible for advising inspection personnel to activate the clean screening exemption process. Once a reduction in queue length to that representing a motorist wait time of less than 60 minutes takes place, reversion to the normal testing protocol shall occur. Each Delaware inspection lane shall independently control clean screen activation. The Division of Motor Vehicles will cap, on an annual basis, the number of vehicles which may be exempted through clean screening by model year in order to prevent failure to meet expected emission reductions. The first year of implementation will have an annual cap of 14,000 vehicles. If the specified number of vehicles clean screened for an individual model year equals the annual cap of emissions for that individual model year, no more vehicles for that model year will be exempt. The maximum allowable number of vehicles to be clean screened will be re-evaluated annually.
6.0 Test Procedures And Standards
6.1 Test procedure requirements. (The test procedure use to perform this test shall conform to the requirements shown in Appendix 6 (a)).
6.1.1 Initial tests (i.e., those occurring for the first time in a test cycle) shall be performed without repair or adjustment at the inspection facility, prior to the test.
6.1.2 An official test, once initiated, shall be performed in its entirety regardless of intermediate outcomes except in the case of invalid test condition or unsafe conditions.
6.1.3 Tests involving measurements shall be performed with equipment that has been calibrated according to the quality control procedures established by the Department
6.1.4 Vehicles shall be rejected from testing, as covered in this section, if the exhaust system is missing or leaking, or if the vehicle is in an unsafe condition for testing.
6.1.5 After an initial failure of any portion of any emission test (idle or two speed idle test) in the LEIM program, all vehicles shall be retested without repairs being performed. This retest shall be indicated on the records as the second chance test. After failure of the second chance test, prior to any subsequent retests, proof of appropriate repairs must be submitted indicating the type of repairs and parts installed (if any). This shall be done by completing the “Vehicle Emissions Repair Report Form” (Appendix 6 (a) (5) which will be distributed to anyone failing the emissions test.)
6.1.6 Idle testing using BAR 90 emission analyzers (analyzers that have been certified by the California Bureau of Automotive Repair) shall be performed on all 1968 through 1995 model year vehicles in New Castle and Kent Counties.
6.1.7 Emission control device inspection. Visual emission control device checks shall be performed through direct observation or through indirect observation using a mirror. These inspections shall include a determination as to whether each subject device is present.
6.1.8 Evaporative System Integrity Test. Vehicles shall fail the evaporative system integrity test(s) if the system(s) cannot maintain the equivalent pressure of eight inches of water for up to two minutes after being pressurized to 14 plus or minus 0.5 inches of water. Additionally, vehicles shall fail evaporative system integrity testing if the canister is missing or obviously disconnected, the hoses are crimped off, or the fuel cap is missing. Evaporative system integrity test procedure is found in See Appendix 6 (a)(8).
6.1.9 Onboard diagnostic checks. Vehicles shall be tested following the procedures found in Appendix 6 (a)(9).
6.2 Test standards
6.2.1 Emissions standards.
HC, CO, CO+CO2 (or CO2 alone), emission standards shall be applicable to all vehicles subject to the LEIM program and repairs shall be required for failure of any standard regardless of the attainment status of the area. Steadystate short tests.
Appropriate model program standards shall be used in idle testing of vehicles from model years 1968 light duty vehicles and model years 1970 light duty trucks and newer.
6.2.2 Visual equipment inspection standards performed by the Motor Vehicle Technician. Vehicles shall fail visual inspections of subject emission control devices if such devices are part of the original certified configuration and are found to be missing, modified, disconnected, or improperly connected.
6.2.3 Onboard diagnostics test standards. Vehicles shall fail the OBD test if: Malfunction Indicator Light (MIL) is not lit during key on, engine off check of bulb; and/or MIL lit (or commanded on) for any Diagnostic Trouble Codes (DTC); Data Link Connector (DLC) is damaged, missing, tampered or obstructed by an after-market device More than two unset readiness codes for model years 1996-2000 unless an exception from this provision is given under the requirements in Appendix 6 (a) (9) for vehicles that have failed the initial test and have been repaired where the monitors are not yet ready to test. In addition, an exception to this provision will be allowed for vehicles listed in Appendix 6 (a) (9) by model and year. More than one unset readiness code for model years 2001 and newer unless an exception from this provision is given under the requirements in Appendix 6 (a) (9) for vehicles that have failed the initial test and have been repaired where the monitors are not yet ready to test. In addition, an exception to this provision will be allowed for vehicles listed in Appendix 6 (a) (9) by model and year.
6.3 Applicability.
In general, section 203(a)(3)(A) of the Clean Air Act prohibits altering a vehicle's configuration such that it changes from a certified to a noncertified configuration. In the inspection process, vehicles that have been altered from their original certified configuration are to be tested by the Motor Vehicle Technician in the same manner as other subject vehicles.
6.3.1 Vehicles with engines of a model year older than the chassis model year shall be required to pass the standards commensurate with the chassis model year.
6.3.2 Vehicles that have been switched from an engine of one fuel type to another fuel type that is subject to the LEIM program (e.g., from a diesel engine to a gasoline engine) shall be subject to the test procedures and standards for the current fuel type, and to the requirements of paragraph (c)(1) of this section.
6.3.3 Vehicles that are switched to a fuel type for which there is no certified configuration shall be tested according to the most stringent emission standards established for that vehicle type and model year. Emission control device requirements may be waived if the Division determines that the alternatively fueled vehicle configuration would meet the new vehicle standards for that model year without such devices.
6.3.4 Vehicles converted to run on alternate fuels, frequently called a dual-fuel vehicle, shall be tested and required to pass the most stringent standard for each fuel type.
6.3.5 Mixing vehicle classes (e.g., lightduty with heavyduty) and certification types (e.g., California with Federal) within a single vehicle configuration shall be considered tampering.
7.0 Waivers And Compliance Via Diagnostic Inspection
7.1 Waiver issuance criteria.
7.1.1 Motorists shall expend a reasonable cost, as defined in Section 1 of this Regulation in order to qualify for a waiver. For vehicles failing the exhaust emissions test under Section 3 (a) (6), in order to qualify for waiver repairs on any 1981 or later model year vehicle shall be performed by a certified repair technician or a certified manufacturer repair technician, as defined in Section 1 of this regulation, and must have been appropriate to correct the emission failure. Repairs of primary emission control components may be performed by nontechnicians (e.g., owners) to apply toward the waiver limit. The waiver would apply to the cost of parts for the repair or replacement of the following list of emission control component systems: Air induction system (air filter, oxygen sensor), catalytic converter system (convertor, preheat catalyst), thermal reactor, EGR system (valve, passage/hose, sensor) PCV System, air injection system (air pump, check valve), ignition system (distributor, ignition wires, coil, spark plugs). The cost of any hoses, gaskets, belts, clamps, brackets or other emission accessories directly associated with these components may also be applied to the waiver limit. For vehicles failing the on-board diagnostics test under Section 3 (b) in order to qualify for waiver, repairs on any 1996 or later model year vehicle shall be performed by a certified repair technician or a certified manufacturer repair technician, as defined in Section 1 of this regulation, and must have been appropriate to correct the emission failure.
7.1.2 Any available warranty coverage shall be used to obtain needed repairs before expenditures can be counted towards the cost limits in paragraph (a)(4) of this section. The operator of a vehicle within the statutory age and mileage coverage under section 207(b) of the Clean Air Act shall present a written denial of warranty coverage from the manufacturer or authorized dealer for this provision to be waived for approved tests applicable to the vehicle.
7.1.3 Receipts shall be submitted for review to further verify that qualifying repairs were performed.
7.1.4 A minimum expenditure for repairs of $75 for pre81 model year vehicles or a minimum expenditure of $200 for 1981 model year and newer vehicles shall be spent in order to qualify for a waiver. The minimum repair cost for 1981 and newer vehicles shall increase to $450 starting January 1, 2000. For each subsequent year, the $450 minimum expenditure shall be adjusted in January of that year by the percentage, if any, by which the Consumer Price Index for the preceding calendar year differs from the Consumer Price Index for 1989.
7.1.5 The issuance of a waiver applies only to those vehicles failing an exhaust emission or on-board diagnostics tests. No waivers are granted to vehicles failing the evaporative emission integrity test.
7.1.6 Waivers shall be issued by the Division Director only after: a vehicle has failed a retest for only the exhaust emissions or on-board diagnostics portions of the program, performed after all qualifying repairs have been completed;
7.1.7 Qualifying repairs include repairs of primary emission control components performed within 90 days of the test date.
7.1.8 Waivers issued pursuant to this regulation are valid until the date of current registration expiration.
7.1.9 Waivers will not be issued to vehicles for tampering related repairs. The cost of tampering related repairs shall not be applicable to the minimum expenditure in paragraph (a)(4) of this section. The Director will issue exemptions for tampering related repairs if it can be verified that the part in question or one similar to it is no longer available for sale
7.2 Compliance via diagnostic inspection.
Vehicles subject to an emission test at the cutpoints shown in Appendix 3 (a)(7) of Regulation 31 may be issued a certificate of compliance without meeting the prescribed emission cutpoints, if, after failing a retest on emissions, a complete, documented physical and functional diagnosis and inspection performed by a Delaware Certified Emission Repair Technician shows that no additional emission related repairs are needed.
7.3 In order to meet the requirements of the EPA Rule, the State commits to maintaining a waiver rate equal to or less than 3% of the failed vehicles.
7.3.1 The Secretary shall take corrective action to lower the waiver rate should the actual rate reported to EPA be above 3%.
7.3.3 Actions to achieve the 3% waiver rate, if required, shall include measures such as not issuing waivers on vehicles less than 6 years old, raising minimum expenditure rates, and limiting waivers to once every four years. If the waiver rate cannot be lowered to levels committed to in the SIP, or if the State chooses not to implement measures to do so, then the Secretary shall revise the I/M emission reduction projections in the SIP and shall implement other LEIM program changes needed to ensure the performance standard is met.
8.0 Motorist Compliance Enforcement.
8.1 Registration denial.
Registration denial enforcement (See Appendix 8 (a), the Systems Requirement Definition for the Registration Denial process) is defined as rejecting an application for initial registration or re-registration of a used vehicle (i.e., a vehicle being registered after the initial retail sale and associated registration) unless the vehicle has complied with the LEIM program requirement prior to granting the application. This enforcement is the express responsibility of the Division with the assistance of police agencies for on road inspection and verification. The law governing the registration of motor vehicles is found in the Delaware Criminal and Traffic Law Manual, Title 21 Del.C. Ch. 21. Pursuant to section 207(g)(3) of the Act, nothing in this section shall be construed to require that new vehicles shall receive emission testing prior to initial retail sale. In designing its enforcement program, the Director shall:
8.1.1 Provide an external, readily visible means of determining vehicle compliance with the registration requirement to facilitate enforcement of the LEIM program. This shall be in the form of a window sticker and tag sticker which clearly indicate the vehicles compliance status and next inspection date;
8.1.2 Adopt a schedule of biennial testing that clearly determines when a vehicle shall have to be inspected to comply prior to (re)registration;
8.1.3 Design a registration denial system which features the electronic transfer of information from the inspection lanes to the Division's Data Base, and monitors the following information: Expiration date of the registration; Unambiguous vehicle identification information; and Whether the vehicle received either a waiver or a certificate of compliance; The Division’s unique windshield certificate identification number to verify authenticity; and The Division shall finally check the inspection database to ensure all program requirements have been met before issuing a vehicle registration.
8.1.4 Ensure that evidence of testing is available and checked for validity at the time of a new registration of a used vehicle or registration renewal.
8.1.5 Prevent owners or lessors from avoiding testing through manipulation of the title or registration system; title transfers do not restart the clock on the inspection cycle.
8.1.6 Limit and track the use of time extensions of the registration requirement to only one 60 day extension per vehicle to prevent repeated extensions.
8.2 Owners of subject vehicles must provide valid proof of having received a passing test or a waiver to the Director’s representative in order to receive registration from the Division.
8.3 State and local enforcement branches, such as police agencies, as part of this program, shall cite motorist who do not visibly display evidence of compliance with the registration and inspection requirements.
8.4 Fleet and all other registered applicable vehicle compliance shall be assured through the regular enforcement mechanisms concurrent with registration renewal, on-road testing and parking lot observation. Fleets shall be inspected at official inspection stations.
8.5 Federal fleet compliance shall be assured through the cooperation of the federal fleet managers as well as also being subject to regular enforcement operations of the Division.
9.0 Enforcement Against Operators And Motor Vehicle Technicians.
9.1 Imposition of penalties
The State of Delaware shall continue to operate the LEIM program using State of Delaware Employees for all functions. Should enforcement actions be required for violations of program requirements, the State of Delaware Merit Rules, shall be adhered to in all matters. Applicable provisions of these documents are found in Appendix 9 (a).
9.2 Legal authority.
9.2.1 The Director shall have the authority to temporarily suspend station Motor Vehicle Technicians' certificates immediately upon finding a violation or upon finding the Motor Vehicle Technician administered emission tests with equipment which had a known failure and that directly affects emission reduction benefits.
9.2.2 The Director shall have the authority to impose disciplinary action against the station manager or the Motor Vehicle Technician, even if the manager had no direct knowledge of the violation but was found to be careless in oversight of motor vehicle technicians or has a history of violations, in accordance with the State of Delaware Merit Rules. The lane manager shall be held fully responsible for performance of the motor vehicle technician in the course of duty.
10.0 Improving Repair Effectiveness.
A prerequisite for a retest shall be a completed repair form that indicates which repairs were performed. (See Section 6 (a) (5) of this Regulation).
11.0 Compliance With Recall Notices.
12.0 On-Road Testing.
12.1 Periodic random Delaware registered vehicle pullovers on Delaware highways will occur without prior notice to the public for on-road vehicle exhaust emission testing.
12.2 Vehicles identified by the on-road testing portion of the LEIM program shall be notified of the requirement for an out-of-cycle emission retest, and shall have 30 days from the date of the notice to appear for inspection. Vehicles not appearing for a retest shall be out of compliance, and be liable for penalties under Title 21 of Delaware Criminal and Traffic Law Manual and the Division will take action to suspend the vehicle registration.
13.0 Implementation Deadlines.
All requirements related to the LEIM program shall be effective ten days after the Secretary’s order has been signed and published in the State Register except for the following provisions that have been amended to this regulation:

Commitment to Extend the I/M Program to the Attainment
Date Letter from Secretary Tulou to EPA
Regional Administrator, W. Michael McCabe
June 1, 1998
Mr. W. Michael McCabe
Regional Administrator
EPA, Region III
841 Chestnut Building
Philadelphia, PA 19107
Dear Mr. McCabe:
This correspondence is to address one of the cited deficiencies published in the May 19, 1997 EPA rulemaking, concerning Delaware’s Inspection and Maintenance regulation. I understand that this letter will address the following deficiency:
Provide a statement from an authorized official that the authority to implement Delaware’s I/M program as stated above will continue through the attainment date . . .
The Delaware I/M regulation has no sunset provision and there is nothing in the Delaware statute that requires our regulations to have a sunset date nor to be re-authorized in order to continue beyond a sunset date.
We fully expect, barring the repeal of 7 Del.C. Chapter 67, the Delaware I/M regulation will be implemented to the full extent of the law through the attainment date and most likely through the maintenance period when that occurs.
Please feel free to contact Darryl Tyler, Program Administrator of the Air Quality Management Section at (302) 739-4791, if you should have any questions.
Christophe A. G. Tulou

APPENDIX 3 (c) (2)
General Requirements
Test Parameters. The following information shall be determined for the vehicle being tested and used to automatically select the dynamometer inertia, power absorption settings, and evaporative emission test parameters.
Model Year
Model name
Body style
Number of cylinders
Engine displacement
Alternative computerized methods of selecting dynamometer test conditions, such as VIN de-coding, may be used.
Ambient Conditions. The ambient temperature, absolute humidity, and barometric pressure shall be recorded continuously during the transient test, or as a single set of readings if taken less than 4 minutes prior to the transient driving cycle.
Restart. If shut off, the vehicle shall be restarted as soon as possible before the test and shall be running at least 30 seconds prior to the transient driving cycle.
During the entire VMASTM testing procedure the vehicle shall be operated by a certified Motor Vehicle Technician (herein called inspector) and the vehicle owner or operator shall be asked to wait in a specified area during the test.
Pre-inspection and Preparation
Accessories. All accessories (air conditioning, heat, defogger, radio, automatic traction control if switchable, etc.) shall be turned off by the inspector, if necessary.
Traction Control and Four-Wheel Drive (4WD). Vehicles with traction control systems that cannot be turned off shall not be tested on two wheel drive dynamometers. Vehicles with 4WD that cannot be turned off shall only be tested on 4WD dynamometers. If the 4WD function can be disabled, then 4WD vehicles may be tested on two wheel drive dynamometers.
Leaks. The vehicle shall be inspected for exhaust leaks. Audio assessment while blocking exhaust flow, or measurement of carbon dioxide or other gases, shall be acceptable. Vehicles with leaking exhaust systems shall be rejected from testing.
Operating Temperature. The vehicle temperature gauge, if equipped and operating, shall be checked to assess temperature. If the temperature gauge indicates that the engine is well below (less than 180(F) normal operating temperature, the vehicle shall not be fast-failed and shall get a second-chance emission test if it fails the initial test for any criteria exhaust component. Vehicles in overheated condition shall be rejected from testing.
Tire Condition. Vehicles shall be rejected from testing if tire cords, bubbles, cuts, or other damage are visible. Vehicles shall be rejected that have space-saver spare tires on the drive axle. Vehicles may be rejected if they do not have reasonably sized tires. Vehicle tires shall be visually checked for adequate pressure level. Drive wheel tires that appear low shall be inflated to approximately 30 psi, or to tire side wall pressure, or manufacturer's recommendation. The tires of vehicles being tested for the purposes of program evaluation under the Code of Federal Regulations Title 40 §51.353(c) shall have their tires inflated to tire side wall pressure.
Ambient Background. [RESERVED]
Sample System Purge. [RESERVED]
Equipment Positioning and Settings
Purge Equipment. If an evaporative system flow meter purge test is to be performed:
The purge flow meter shall be connected in series between the evaporative canister and the engine.
All hoses disconnected for the test shall be reconnected after a purge flow test is performed.
Roll Rotation. The vehicle shall be maneuvered onto the dynamometer with the drive wheels positioned on the dynamometer rolls. Prior to test initiation, the rolls shall be rotated until the vehicle laterally stabilizes on the dynamometer. Drive wheel tires shall be dried if necessary to prevent slippage during the initial acceleration.
Cooling System. The use of a cooling system is optional when testing at temperatures below 50(F). Furthermore, the hood may be opened at the state's discretion. If a cooling system is in use, testing shall not begin until the cooling system is positioned and activated. The cooling system shall be positioned to direct air to the vehicle cooling system, but shall not be directed at the catalytic converter.
Vehicle Restraint. Testing shall not begin until the vehicle is restrained. Any restraint system shall meet the requirements of the Code of Federal Regulations Title 40, §85.2226(a)(5)(vii). The parking brake shall be set for front wheel drive vehicles prior to the start of the test. The parking brake need not be set for vehicles that release the parking brake automatically when the transmission is put in gear.
Dynamometer Settings. Dynamometer power absorption and inertia weight settings shall be automatically chosen from an EPA-supplied electronic look-up table which will be referenced based upon the vehicle identification information obtained in Code of Federal Regulations Title 40, §85.2221(a)(1). Vehicles not listed shall be tested using default power absorption and inertia settings in the latest version of the EPA I/M Look-up Table, as posted on EPA's web site:
Exhaust Collection System. The exhaust collection system shall be positioned to insure complete capture of the entire exhaust stream from the tailpipe during the transient driving cycle. The system shall meet the requirements of §85.2226(b)(2) in the Code of Federal Regulations Title 40,.
Vehicle Conditioning
Queuing Time. Not applicable
Program Evaluation. Vehicles being tested for the purpose of program evaluation under Section 3 (c) (2) shall receive two full VMAS emission tests (i.e., a full 240 seconds each). Results from both tests and the test order shall be separately recorded in the test record. Emission scores and results provided to the motorist may be from either test.
Discretionary Preconditioning.
Any vehicle may be preconditioned by maneuvering the vehicle on to the dynamometer and driving the 94 to 239 second segment of the transient cycle in § 85.2221(e)(1) Code of Federal Regulations Title 40,. This method has been demonstrated to adequately precondition the vast majority of vehicles (SAE 962091). Other preconditioning cycles may be developed and used if approved by the Administrator of the USEPA.
Second-Chance Purge Testing. Not applicable
Vehicle Emission Test Sequence
Transient Driving Cycle. The vehicle shall be driven over the following cycle:
Table A
Driving Trace. The inspector shall follow an electronic, visual depiction of the time/speed relationship of the transient driving cycle (hereinafter, the trace). The visual depiction of the trace shall be of sufficient magnification and adequate detail to allow accurate tracking by the inspector/driver and shall permit anticipation of upcoming speed changes. The trace shall also clearly indicate gear shifts as specified in paragraph (3) and Table B below.
Shift Schedule. To identify gear changes for manual shift vehicles, the driving display presented to the inspector/driver shall be designed according to the following shift schedule and prominently display visual cues where the inspector/driver is required to change gears:
Table B
Gear shifts shall occur at the points in the driving cycle where the specified speeds are obtained. For vehicles with fewer than six forward gears the same schedule shall be followed with shifts above the highest gear disregarded.
Automatic shift vehicles with overdrive or fuel economy drive modes shall be driven in those modes.
(4) Speed Excursion Limits. Speed excursion limits shall apply as follows:
(1) The upper limit is 2 mph higher than the highest point on the trace within 1 second of the given time.
(2) The lower limit is 2 mph lower than the lowest point on the trace within 1 second of the given time.
(3) Vehicle speed excursions beyond tolerance limits given in items a. and b. above are acceptable provided that each such excursion is not more than 2 seconds in duration.
(4) Speeds lower than those prescribed during accelerations are acceptable provided the vehicle is operated at maximum available power during such accelerations until the vehicle speed is within the excursion limits.
[Reserved : Criteria that shall allow limited excursions of speed higher than the prescribed upper limit in paragraphs (i) through (iii) ]
A transient emissions test shall be void and the vehicle retested if the speed excursion limits prescribed by paragraphs (i) through (iii) are exceeded, except in the event that computer algorithms, developed by the Department, determine that the conditions of paragraphs (v) and (vi) are applicable. Tests may be aborted if the speed excursion limits are exceeded.
