RE: Approving Final Regulations to Amend 7 DE Admin. Code 1126 - Motor Vehicle Emissions Inspection Program

Date of Issuance: December 14, 2022

Effective Date of the Amendment: January 11, 2023

1126 Motor Vehicle Emissions Inspection Program

Under the authority vested in the Secretary of the Department of Natural Resources and Environmental Control ("Department" or "DNREC"), pursuant to 7 Del.C. §§6006 and 6010, and all other relevant statutory authority, the following findings of fact based on the record, reasons and conclusions are entered as an Order of the Secretary in the above-referenced promulgation.

Background, Procedural History and Findings of Fact

This Order relates to the proposed regulation amendments ("Amendments") to 1126 - Motor Vehicle Emissions Inspection Program ("Regulation"). Specifically, the Department is amending the Regulation for Sussex County's vehicle Inspection and Maintenance ("I/M") program to: (1) align with Delaware's House Bill 246 (2017) ("HB246") as codified in 21 Del.C. § 2143, expanding the vehicle I/M program model year exemption from five to seven years; (2) replace the current curb idle tailpipe test with On-Board Diagnostic Test ("OBD") on vehicles that weigh up to 8,500 pounds gross vehicle weight, beginning with model year 1996 and newer; (3) require vehicles that weigh 8,501 up to 14,000 pounds gross vehicle weight, beginning with vehicle model year 2008, to undergo an OBD test; (4) modify that in addition to the curb idle tailpipe test, vehicle model year 1995 and older will also be required to include gas cap tests; (5) add language to clarify and prevent tampering of emission controls; and (6) phase in an increased cost of repairs for receiving a program waiver in Sussex County. In turn, the proposed Amendments will establish identical emissions testing requirements statewide.

The Clean Air Act ("CAA") authorized the U.S. Environmental Protection Agency ("EPA") to establish the National Ambient Air Quality Standards ("NAAQS") for criteria pollutants shown to threaten human health, welfare, and the environment. Throughout the State, Delaware has 11 monitoring stations to measure air pollution concentrations of the pollutants through their ambient air monitoring network. Most of the monitoring stations are concentrated in the northern urban/industrial areas, such as New Castle County, that have the highest population and number of pollutant sources. When levels of pollutants measure above NAAQS, the EPA designates the area as nonattainment.

Today, the largest source of ozone pollution in Delaware is from the onroad cars and trucks. Motor vehicles are significant contributors of volatile organic compounds, carbon monoxide, and nitrogen oxide emissions. A control measure to reduce these emissions is the implementation of a motor vehicle I/M program.

In 1977, the CAA established a vehicle I/M program to reduce pollutants and set the standards to meet NAAQS. Delaware began the development of the I/M program in 1979 through a State Implementation Plan ("SIP"). In 1982, Delaware then established 7 DE Admin. Code 1126 to regulate the I/M program for New Castle County. Soon after, on January 1, 1983, the I/M program was formally adopted into Delaware's SIP. Subsequent to establishing the regulation and SIP for the New Castle County I/M program, Delaware expanded the I/M program to all three counties to include Kent County and Sussex County. During that time, the EPA designated Sussex County as "marginal" nonattainment and New Castle County and Kent County were designated as "severe" nonattainment, under the one-hour ozone standard.

In 1990, the CAA amended the vehicle I/M program to require that polluted areas adopt either the ''basic'' or ''enhanced'' I/M programs, depending on the severity of the problem and the population of the area. The "basic" vehicle I/M requirements were provided for moderate ozone nonattainment areas, and marginal ozone areas with existing or previously required I/M programs with populations of 200,000 or more. The "enhanced" vehicle I/M requirements were provided for more polluted areas classified as serious, severe, and extreme nonattainment areas with populations of 200,000 or more. The EPA's rule for the "enhanced" I/M program established two standards codified in 40 CFR 51.351(f) - High Enhanced Performance Standard and 40 CFR 51.351(g) - Low Enhanced Performance Standard. The "high enhanced" performance standard achieves a greater reduction in emissions and uses a highly technical test method. The "low enhanced" performance standard provides flexibility for nonattainment areas that are required to implement enhanced I/M programs and can meet the Act's emission reduction requirements for reasonable further progress (referred to as 15% plans) and attainment from other sources. States may select the low enhanced performance standard if they have an approved SIP for 15%.

As a result of Sussex County being designated as "marginal" non-attainment, Delaware implemented the performance standards for the "basic" I/M program in Sussex County. Similarly New Castle and Kent County were nonattainment, with being designated as "severe" and Delaware implemented the "Low Enhanced" I/M program. Subsequent to the CAA revisions in 1990, Delaware revised the SIP to address the "low enhanced" performance standards for Kent and New Castle County. The SIP revisions consisted of revisions to Regulation 1126 and a new Regulation 1131. It should be noted that New Castle County and Kent County were then regulated under 7 DE Admin. Code 1131, the "low enhanced" I/M program, to address higher levels of pollutants.

In 2017, Delaware enacted HB246 to provide a higher level of service to DMV customers and provide a more efficient renewal processes for vehicle owners. The enactment of HB246 increased the exemption for vehicle emission inspections from 5-years to 7-years, for all new vehicle models. The enactment of this legislation reduces the number of inspections per year by approximately 45,000 vehicles and enables all owners of vehicles within the most recent 7-year vehicle model to easily renew their registration.

The passage of HB246 meant fewer inspections in Kent and New Castle County and this meant an increase of 19.2 tons of nitrogen oxides and 15.3 tons of volatile organic compounds. Fewer inspections in Sussex County meant an increase of 1.1 tons per year in volatile organic compounds with no emissions benefit. These emission increases triggered the Department to review the vehicle emission program and implement measures to reduce the levels of emissions impacted by the new legislation. It should be noted that Sussex County reported no impact on nitrogen oxides.

The Department worked with the Department of Motor Vehicles ("DMV") to analyze several scenarios to offset the aforementioned emission increases caused by HB246. The Department concluded the best scenario to provide a sufficient reduction of emission increases would be to add an on-board diagnostic test for vehicles weighing 8,500 pounds up to 14,000 pounds, a single-speed idle test for vehicle model years 1968 to 1995 weighing up to 8,500 pounds, and a gas cap test for vehicle model years 1975 to 1995 weighing up to 8,500 pounds. This scenario will reduce emissions from the current emission levels by 391.1 tons per year of CO, 101.6 tons per year of NOx and 45.6 tons per year of VOC's. This scenario would provide the most beneficial reduction in vehicle emissions for all three counties.

The Department then consulted with EPA's Region 3 staff and it was decided that the emission reductions attributed to adding onboard diagnostic testing programs in Sussex County could be used to offset, in part, the emissions increases attributed to the vehicle emissions exemption extension for Kent and New Castle Counties. As Delaware drivers travel through the three counties, the use of Sussex County reductions towards offsetting Kent and New Castle County's vehicle emissions supports the use for offsetting emission reductions.

As a part of the review process of Delaware's vehicle I/M program, the Department conducted one in-person public meeting, and two additional virtual public meetings to address the proposed changes and receive feedback from those in attendance. A survey was conducted after the meetings and the Department received two responses in regard to the Sussex County vehicle I/M program. After the public meetings, the Department considered the public comments and then proceeded with the formal promulgation of the Amendments.

Further, the Amendments maintain consistency with current federal regulations, 40 CFR 51 50 Subpart S - Inspection and Maintenance Program Requirements, the CAA (42 U. S. C. 7522(a)) Section 203 and State Regulation 21 Del. C. Ch. 21, Registration of Vehicles (§§ 2109, 2110, and 2143). As such, the Amendments encourage proper vehicle maintenance, discourage tampering of vehicle emission controls by vehicle owners, reduce vehicle emissions, improve air quality, help maintain a healthy environment, and help provide improved health related impacts.

The Department published its initial proposed Amendments in the September 1, 2022 Delaware Register of Regulations. After the public hearing notice was issued, the Department revised the proposed Amendments to include a non-substantive change. The virtual public hearing regarding this matter was held on September 29, 2022. There were two (2) members of the public in attendance at the virtual public hearing.

Pursuant to 29 Del.C. §10118(a), the hearing record remained open for receipt of written comment for 15 days following the public hearing. The hearing record formally closed for comment in this matter at close of business on October 14, 2022, with no comments received by the Department during this phase of the formal promulgation. It should be noted that the proposed revised Amendments were fully vetted at the time of the virtual public hearing.

Thereafter, Hearing Officer Theresa Newman prepared her report dated November 3, 2022 ("Report"), which expressly incorporated the Department's proposed Amendments into the hearing record generated in this matter. The Report documents the proper completion of the required regulatory amendment process, establishes the record, and recommends the adoption of the proposed revised Amendments as attached to the Report as Appendix "A."

The Department has the statutory basis and legal authority to act with regard to the formal promulgation of these proposed revised Amendments, pursuant to 7 Del.C. §6010(a) and (c). It should be noted that all notification and noticing requirements concerning this matter were met by the Department. Proper notice of the hearing was provided as required by law.

Reasons and Conclusions

Based on the record developed by the Department's staff in the Division of Air Quality, and established by the Hearing Officer's Report, I find that the proposed revised regulatory Amendments are well-supported and will enable the Department to: (1) expand the vehicle I/M program model year exemption from five to seven years; (2) replace the current curb idle tailpipe test with OBD on vehicles that weigh up to 8,500 pounds gross vehicle weight, beginning with model year 1996 and newer; (3) require vehicles that weigh 8,501 up to 14,000 pounds gross vehicle weight, beginning with model year 2008, to undergo an OBD test; (4) modify that in addition to curb idle tailpipe test, vehicle model years 1995 and older will also be required to include gas cap tests; (5) add language to clarify and prevent tampering of emission controls; and (6) phase in an increased cost of repairs for receiving a program waiver in Sussex County. I further find that the Department's Air Quality experts fully developed the record to support adoption of these Amendments. Therefore, the recommendations of the Hearing Officer are hereby adopted, and I direct that the proposed revised Amendments be promulgated as final.

TECHNICAL MEMORANDUM #1

DELAWARE DIVISION OF MOTOR VEHICLES VEHICLE EXHAUST EMISSIONS TEST

To describe the details of the DMV exhaust emissions test for HC and CO using DE '95 Inspection system composed of exhaust emissions and pressure test analyzers manufactured by Environmental Systems Products, Inc., E. Granby, CT (ESP)

Applicable to all gasoline (or alternate fueled) vehicles presented for inspection (regular renewal) in Delaware.

3.1 ESP Lane Operator's Manual, Version #2 (1997)

3.2 DMV 9701 Gas Calibration

3.3 ESP DW6 HT202561 (Rev. L 06/27/95)

3.4 Delaware exhaust emissions specification limits

3.5 ESP BAR 90 Certification for analyzer bench

3.6 ESP exhaust emissions measurement system P/N ESP 10364-2

4.1 The lane analyzer has successfully passed the calibration procedure or procedures noted in Sections 2.1-2.2 of the ESP Lane Operator's Manual and DMV9701.

4.2 The Certified DMV Technician has verified that the vehicle presented is a viable candidate for an exhaust emissions analysis using DE '95 equipment.

4.3 The DMV Technician verifies that the following criteria are satisfied prior to emissions analysis.

4.3.1 Analyzer is "clean"; a HC hang-up condition exists when HC reading is greater than 40 PPM and the analyzer "locks-out" until the purge indicates "clean".

4.3.2 After the Technician inserts the exhaust pipe probe insertion (see note (a)), to a minimum of 10 inches, the resultant sample dilution (CO+CO2) must exceed 6.0%. The analyzer indicates the presence of a failure condition (CO+CO2<6.0%) and indicates "test voided". If the (CO+CO2) condition is not satisfied, the subject vehicle FAILS the Delaware Emissions Test.

(a) Normally, the vehicle driver has been requested to "fast idle" the vehicle for 30 seconds prior to entering the inspection lane, however, the Technician does not verify this condition.

4.4 When those conditions indicated in 4.3 of this memorandum are satisfied, the analyzer begins a timed emissions test. The following sequence prevails:

4.4.1 The test sequence is:

4.4.1.1 The internal timer starts; the analyzer "collects" samples for 15 seconds at a rate of two samples per second;

4.4.1.2 At the 15 second interval, the analyzer compares the accumulated data to the applicable DE emissions specification for Hydrocarbons HC and Carbon Monoxide CO;

4.4.1.3 Should the analyzer determine that the accumulated data does not exceed specifications for both components, it stops testing and indicates that the vehicle has passed emissions testing;

4.4.1.4 If the above analysis indicates that the applicable specifications limits are exceeded, sampling continues at the prescribed rate for an additional 15 seconds;

4.4.1.5 During this additional 15 second interval the analyzer continually compares the resultant data to the applicable DE specification. If, during this time, the HC & CO data are within specification, sampling ceases and a PASS indication is indicated; If, at the end of a 30 second sampling, either or both the HC and CO data exceed specification, testing is terminated and a FAILURE is noted. An immediate exhaust emissions retest is provided to all vehicles failing their initial emissions test. Subsequent "retests" shall only be performed after a properly completed "DMV VEHICLE EMISSIONS REPAIR FORM" is presented.

Revised 12/29/1987

TECHNICAL MEMORANDUM #2

MOTOR VEHICLE INSPECTION AND MAINTENANCE PROGRAM EMISSION LIMIT DETERMINATION

The five vehicle age groups have different allowable emission rates in the idle mode due to the sophistication of the emission control equipment installed by the manufacturer. The only exception being the pre-1968 age group which had no pollution control apparatus, saved for a few vehicles with positive crankcase ventilation (PCV) valves. Installation of PCV valves was virtually a voluntary measure by auto manufacturers.

During the time period March 1 through June 30, 1982, data was being gathered by a mandatory emission inspection with voluntary repair, at the two vehicle safety inspection lanes in New Castle County. The Sun Model CEA-3023 Computer Emission Analyzer (hereafter called the analyzer) has the ability to store, on conventional data cassettes, all of the input required and the results of a test on every vehicle tested. This is to include date, time, vehicle age group, vehicle registration number, hydrocarbon (HC) and carbon monoxide (CO) emission limits for the particular vehicle age group and the actual HC and CO emissions from the tested vehicle. A paper printout of this information is given to the driver upon being tested. Test procedures were consistent with those described in Appendix B to Technical Memorandum #1.

During the voluntary emission program, the HC and CO emission limits programmed into the analyzer were, with one exception, the same as those used by the State of New Jersey in its I & M program. Using these limits or "cut points" for each vehicle type gave a very good frame of reference to analyze the limits applicable to Delaware.

In general, about 25% of the vehicles tested during that voluntary program failed to pass the New Jersey standards.

Emission limits for each age group and the failure rate as a percent are shown in Table 1 of this memorandum.

Table 1

Notes: (1) Hydrocarbon (HC) emissions expressed as parts per million (ppm) of non-methane HC.

(2) The New Jersey standards for 1980 and later models are 300 ppm of HC.

The rate of emission reduction required by the I & M program adoption must be at least 35% reduction of total HC emissions from tailpipe at the end of 1987. The 35% is defined as the difference in emissions of HC between the vehicle fleet not having I & M and that having I & M, in the urbanized portion of the ozone non-attainment area. Since the mechanics of testing only those vehicles registered to an address within the "urbanized"(1) area would be difficult at best, the entire county was included in the calculations for reductions.(2) The types of vehicles to be tested for emissions were broadened to include the two classes of light duty trucks, those under 6,000 pounds G. V. W. and those in the 6,000 to 8,500 pound G.V.W. class. These two measures reduced the estimated failure rate from the 20% of the urbanized auto and station wagon fleet, which is the target rate to accomplish the 35% reduction in the emissions, down to 15%.

Attached as Appendix A to this Technical Memorandum is an April 16, 1982, letter from the I & M staff at EPA's Ann Arbor office. This letter details their evaluation of a 10% stringency factor on the three LD classes of vehicles in NCC to provide at least 35% reduction in tailpipe emissions. Following up the EPA analysis is a similar analysis for the Delaware-specific data. With a 15% stringency factor the results show that a 39.7% reduction in HC will be realized when the same 1,083 factor for "entire county inspection" is applied. This is obviously a reduction in tailpipe HC emissions adequate to meet the EPA requirements.

The selection of cut points for each vehicle class was accomplished by computer storage and retrieval of the data. For each vehicle age group, the frequency of each emission reading was determined and the appropriate percentile selected as the cut point for that particular age group. For simplicity and reduced computer storage requirements each individual reading was grouped in sets of 5 ppm, in the case of HC, and in sets of 0.05%, in the case of CO.

Light duty trucks (pickups and vans) have different levels of emission controls than those of autos. Age groups of the two light duty gasoline truck classes LDGT1(3) and LDGT2(4) had to be fit into one of the auto age group levels of emission control. This determination was made by utilizing Table 7 of the January, 1981, EPA document entitled "Recommendations Regarding the Selection of Idle Emission Inspection Cutpoints for Inspection and Maintenance Programs". The final result of this exercise is shown in Table 2 of this memorandum, and this table represents the cutpoints adopted in the 1982 S.I.P. revision. Since the County of New Castle is non-attainment for ozone which is affected by HC, the rates shown for CO will be recorded, but failure of CO limits will not affect registration of the vehicle.

(1) The urbanized area as defined by the U.S. Bureau of the Census.

(2) This expanded the potential vehicle fleet by a factor of 1.083 which is the ratio of total NCC population to the urbanized area population.

(3) Truck with GVW less than 6,000 pounds

(4) Truck with GVW greater than 6,000 but less than 8,500 pounds
