Implementation Plan for In spection/Maintenance Program

INTRODUCTION

The State of North Carolina implemented a Motor Vehicle Inspection/Maintenance (I/M) program under Environmental Protection Agency (EPA) regulations in Code of Federal Regulations (CFR) 40 CFR Part 51. The implementation of this program con tinues to be an integral part of North Carolina’s plan to attain and maintain compliance with the National Ambient Air Quality Standards (NAAQS) for ozone (O 3 ) and carbon monoxide (CO).

The Division of Motor Vehicles (DMV), License and Th eft Bureau, has operational responsibility for the I/M program, and has created rules for implemen ting and monitoring the program under the North Carolina Administrative Code (NCAC) Title 19A 03D.05. The Division of Air Quality (DAQ) is responsible for monitoring the DMV’s adherence to EPA’s guidelines and reporting to EPA each year (per 40 CFR 51.366 ) detailing the activity of North Carolin a’s I/M program. In addition, the DAQ develops specifications for the program and certifies the emissions testing equipment used in the program.

The North Carolina I/M program began in 1982 in Mecklenburg County. From 1986 through1991, the program expanded to include eight additional counties, based on a “tail-pipe” emissions test. In 1999, the North Carolina General Assembly passed legislation to require an On-Board Diagnostic II (OBD) I/M program in not only the counties required to have an I/M program under 40 CFR 51.350(a), but also in other counties in the State that may need the additi onal emission reductions to achieve the 1997 8-hour ozone standard. Starting in October 2002, the original nine counties converted from tail-pipe testing to the new OBD emissions testing for all model year (MY) 1996 and newer light duty gasoline vehicles. The program began to expand from nine counties starti ng July 1, 2002 to a total of 48 counties on January 1, 2006. At the time of full implementation of the OBD program, inspection stations were performing the OBD emissions test on MY 1996 and newer vehicles, a nd tailpipe testing for MY 1995 and older vehicles were discontinued.

In 2002, North Carolina inspection stations performed over 2.5 million vehicle emission inspections. As the new I/M counties were added, the number of inspections was expected to rise to a high of about 3.5 million inspections but then dip to a lower figure when all tail pipe testing ended on Dec 31, 2005. The actual number of OBD inspections has varied from 4. 2 to 4.6 million since 2006, due to higher than expected fleet turnover and population growth.

On November 1, 2008, the State ended the use of pa per stickers and began the process of aligning vehicle inspection expiration and registration renewal dates by using electronic inspection authorizations. By aligning the two dates the State hopes to improve the vehicle compliance because vehicles will be required to have a passing OBD inspection no more than 90 days prior to the vehicle registration expiration date in order to renew their registration.

## A. APPLICABILITY ( 40 CFR §51.350)

1. In North Carolina, Table 1 below lists the c ounties required to have an I/M program as described in 40 CFR 51.350(a), due to being designated nonatta inment for CO or Moderate O 3 . Although only part of Granville County was designated Moderate nonattainment for the 1-hour O 3 standard, the whole County was subject to the I/M program. Similarly with Iredell County, where only a portion of the County was designated as Moderate for the 8-hour O 3 standard, the whole County is subject to the I/M program.

2. In 1999, the North Carolina General Assembly passed legislation to require an OBD I/M program in not only the counties required to have an I/M program under 40 CFR 51.350(a), but also in other counties in the State that may need the additional emission reductions to achieve the 1997 8-hour ozone standard. The North Carolina General Statue (NCGS) §143- 215.107A(c) specifies the counties that are required to have OBD I/M. The State regulations NCAC Title 15A, Subchapter 2D, Section .1000, “Motor Vehicle Emission Control Standard”

North Carolina I/M SIP May 21, 2010 2references the General Statue. Table 2 below lis ts the additional counties that are required to have an I/M program per NCGS §143-215.107A.

North Carolina I/M SIP May 21, 2010 33. The Environmental Management Commission (EMC) has the authority to adopt “a program for testing emissions from motor vehicles and to adopt motor vehicle emission standards”, NCGS §143-215.107. (a)(6), “Air Quality Standards and Classifications.”

The EMC has adopted a basic I/M program, NCAC, Title 15A, Subchapter 2D, Section .1000, “Motor Vehicle Emissions Control Standard.”

The I/M program is implemented by the Commissioner of the DMV through the use of licensed safety/emission inspection stations, NCGS Article 3 – Motor Vehicle Act of 1937 §20-128.2 (a), “Motor vehicle emission standards.”

4. 40 CFR 51.372(a) (3) requires ZIP codes be included in the State Implementation Plan (SIP) if program is not county-wide. The North Carolina program is county wide, so no list of program area ZIP codes is required.



## B. ENHANCED I/M PERFORMANC E STANDARD (40 CFR §51.351)

Not applicable to North Carolina.



## C. BASIC I/M PERFORMANCE STANDARD (40 CFR §51.352)

1. Basic I/M Performance Standards for 1-hour O 3 and CO standards In 1993, North Carolina submitted an I/M SIP to address the I/M requirements for the 1-hour O 3 and CO standards. The original perfor mance standards for Volatile Organic Compounds (VOC) and CO are summarized below. These performance standards were calculated using the latest EPA mobile model at that time, MOBILE5a. Appendix 1 contains the MOBILE5a input and output files from the runs used to evaluate the emission reduction benefits.

VOC Emission Factors (grams/mile)

1997 2000 2003

Performance Standard 2.32 2.09 1.94

Program Target 2.30 2.08 1.92

CO Emission Factors (grams/mile)

1996 2000

Performance Standard 26.74 24.46

Program Target 26.53 24.34

2. Basic I/M Performance Standards for the 1997 8-hour O 3 standard In June 2004, the EPA designated areas as nonattainment for the 1997 8-hour O 3 standard. One area in North Carolina was designated as Moderate nonattainment, the CharlotteGastonia-Rock Hill, NC-SC area (referred to as the Metrolina area). The North Carolina portion of the Metrolina area includes Cabarru s, Gaston, Lincoln, Mecklenburg, Rowan, Union Counties and Coddle Creek and Davidson Townships in Iredell County. With this

North Carolina I/M SIP May 21, 2010 4designation, additional counties were required under 40 CFR 51.350(a) to implement an I/M
program.

Since Mecklenburg and Gaston Counties had b een designated Moderate nonattainment for the 1-hour O3 standard, the performance sta ndards for these two counties are established in 40 CFR 51.352(c). The results of the performance standards are summarized below. Appendix 1 contains the input and output files for MOBILE6.2 runs performed to evaluate the emission benefits of the basic I/M areas in these two counties.

Emission Factors for Mecklenburg and Gaston Counties (grams/mile)

VOC NOx

Performance Standard 0.784 0.750

Program Target 0.726 0.688

The remaining counties in the Metrolina nona ttainment area are required to meet the performance standards established in 40 CFR 51.352(e). The results of the performance standards are summarized below. Appendix 1 contains the input and output files for MOBILE6.2 runs performed to evaluate the em ission benefits of the basic I/M areas in these counties.

Emission Factors for Remaining Counties (grams/mile)

VOC NOx

Performance Standard 1.363 1.027

Program Target 1.280 0.936

3. The I/M program meets the emission reduction targets in the attainment year and each milestone year prior to the attainment year, as applicable. The State of North Carolina commits to meeting the performance standard.

4. The MOBILE input and output files for runs used in determining compliance with the performance standards are included in Appendix 1. Appendix 2 contains the modeling assumptions, which includes a description of the local inputs used in the modeling, a description of the source from which those inputs were derived, and a description of how they were derived.



## D. NETWORK TYPE AND PROGRAM EV ALUATION (40 CFR §51.353)

1. North Carolina’s basic I/M program is comprised of a decentralized network of test-andrepair facilities. No counties are currently requi red to be part of an Enhanced I/M program. The program consists of appr oximately 4,464 stations.

The DAQ has regional staff that conduct a ra ndom vehicle survey in each I/M county annually, to determine the compliance of th e sampled vehicles and the DMV’s execution of registration denial on those out of compliance. The State continues to determine program effectiveness although basic I/M programs are not required to include an ongoing evaluation

North Carolina I/M SIP May 21, 2010 5to quantify the emission reduction benefits of th e program or to determine if the program is meeting the requirements of the Clean Air Act



### .



## E. ADEQUATE TOOLS AND RE SOURCES (40 CFR §51.354)

1. The I/M program is funded by receipts collected from the sale of electronic I/M inspection authorizations. A portion of these monies are accredited to the DAQ and DMV, as directed in NCGS Article 3A – Safety and Emissions Inspection Program §20-183.7(c), “Fees for performing an inspection and issuing an electroni c inspection authorization to a vehicle; use of civil penalties.”

Inspection fee Station Fee $23.75 Authorization Fee $6.25 $30.00

The authorization fee is distributed as follows: Highway Fund $0.55 Inspection Program Account 3.00 Telecommunications Account 1.75 Volunteer Rescue/EMS Fund 0.18 Rescue Squad Workers' Relief Fund 0.12 Division of Air Quality 0.65 $6.25

The DAQ portion of the fee is credited to the DAQ I/M Air Pollution Control Account. This is a nonreverting fund established for developi ng and implementing air pollution control programs for mobile sources, NCGS §143-215.3A (b1), 

### “ Water and Air Quality Account; use of application and permit fees; Title V A ccount; I & M Air Pollution Control Account; reports.”

The DMV I/M budget is a nonreverting account within the North Carolina Department of Transportation’s (NCDOT) Inspection Program Account. Revenue in the Inspection Program Account may be used only to fund the vehicle I/M program.

2. Appendix 3 includes DAQ and DMV budgets for Fiscal Years 2010-2011 (Note: State fiscal year runs from July 1 through June 30).

The DAQ I/M Air Pollution Control Account funds 10 I/M positions within DAQ. The DAQ employs two full time engineers, one specia list, and one supervisor that perform the day to day program duties which include but are not limited to data analysis, EPA annual reporting, consumer outreach, and software /analyzer certification and specification development. DAQ also has six regional auditors that perform annual audits of DMV staff’s enforcement activities on an annual basis. Additionally, the DAQ I/M staff supports the periodic analyzer recertification testing and other such activities.

The License & Theft Bureau of the DMV is tasked with oversight and enforcement of the I/M program for North Carolina. The DMV has 147 “sworn” law enforcement agents that issue vehicle waivers and perform some covert audits . They are also the enforcement arm of the

North Carolina I/M SIP May 21, 2010 6agency and are responsible for investigating all clean scan cases and handling all criminal charges. The DMV’s 61 civilian auditors are t asked with performing overt and covert audits on approximately 4,464 emission stations in No rth Carolina. The civilian auditors and law enforcement agents also perform remote aud its on the inspection stations. Waivers and exemptions are issued by the auditors and law enforcement agents with in the eight districts throughout North Carolina. Additionally, the DMV employs a six member civilian staff Call Center for consumers to report complaints a nd inquiries on emission inspection requirements and information. The DMV employs personnel to handle the registration denial system.



## F. TEST FREQUENCY AND CONVENIENCE (40 CFR §51.355)

1. The current test frequency of North Carolina’s b asic I/M inspection is annual. In addition, North Carolina has a 1-year new ve hicle exemption, as described in NCAC Title 15A, Section 2D.1005, “On-Board Diagnostic Standards” and NCGS § 20-183.2. “Description of vehicles subject to safety or emissions inspection; definitions.” In addition, an emissions component tamper and safety inspection is performed statewide on all vehicles no more than 35 years old, measured from the date of manufacture, NCGS Article 3A – Safety and Emissions Inspection Programs §20-183.3 (a), “Scope of sa fety inspection and emissions inspection.”

2. Subject vehicles are required to have an annua l OBD inspection no more than 90 days prior to the vehicle registration expiration date, NCGS Article 3 – § 20-183.4C, “When a vehicle must be inspected; three-day trip permit.” All North Carolina law-enforcement officers ha ve the power to enforce the provisions of NCGS Article 3 – Motor Vehicle Act of 1937 §20-183

, “Duties and powers of lawenforcement officers; warning by local officers before stopping another vehicle on highway; warning tickets.”

3. The DMV “Safety and Emissions Regulation Manual” requires stations to operate at least eight hours per day five days per week, except holid ays. Stations are required to have at least one inspector mechanic on duty a minimum of eight hours during normal working hours. Stations may operate other than 8:00 AM to 5:00 PM Monday through Friday schedule. At least one inspector mechanic at a station mu st be licensed. The DMV is responsible for licensing of the inspector mechanics as outlined in Section R.



## G. VEHICLE COVERAGE (40 CFR §51.356)

1. An I/M inspection is required for all 1996 a nd newer model year gasoline-powered vehicles (light-duty) registered in I/M subject areas, NCAC Title 15A, Subchapter 2D, Section .1005, “On-Board Diagnostic Standards” and NCGS §143-215.107A, “Motor vehicle emissions testing and maintenance program.” A table showing the number of vehicles by county and model year for 2009 is contained in Appendix 4. These figures reflect the number of registered vehicles believed to be operated in the I/M area.

2. The following highway vehicles are exempt fro m the I/M requirement: the current model year, all 1995 and older model vehicles, diesel vehicles, heavy-duty vehicles, alternative fueled vehicles, and motorcycles. These vehicles are subject to the annual safety inspection, which includes an emissions control device tampering inspection. Vehicles registered as “Kit cars” are exempt from the OBD portion of the inspection.

North Carolina I/M SIP May 21, 2010 73. The DMV may collect fleet information dir ectly from the owners or from the vehicle registration records concerning the number of vehicles operated in an I/M county but registered in a non-I/M county and vice versa. Enforcement will continue to be registration denial.

4. Fleet vehicles are subject to the program if registered in or primarily operated in a designated I/M county. Fleet owners are allowed to self-inspect their vehicles, NCGS Article 3A Safety and Emissions Inspection Program §20.183-4A, “License required to perform safety inspection; qualifications for license.”

Federal fleet vehicles are required to meet the same requirements as other fleets. EPA’s I/M rules require that federal employees working at a federal facility within an I/M county must comply with the I/M program even if they liv e outside the I/M county. There are federal facilities located in I/M subject areas in North Carolina.



## H. TEST PROCEDURES AND ST ANDARDS (40 CFR §51.357)

1. The EMC has the authority to establish test procedures and standards under NCGS §143- 215.107 (6), “Air quality standards and classifications.”

The EMC has adopted test standards under NCAC, Title 15A, Subch apter 2D, Section .1000, “Motor Vehicle Emission Control Standard.”

The EMC has also adopted test procedures developed by the DAQ and outlined in, “North Carolina Analyzer System Specification”, using EPA’s OBD Test procedures on an OBD type analyzer. The OBD test procedures and standards were implemented July 1, 2002.

2. Vehicles must pass the safety inspection, tampering inspection, and OBD test to receive a safety/emissions authorization. All vehicles fa iling any part of an initial test must pass a retest. If the initial failure was an emissions related item (check engi ne light commanded on, emissions control device tampering or exhaust system), the OBD test must be repeated and passed. If the vehicle owner takes the vehicle to a station other than the original location of the initial test failure, the vehicle must be tested for and pass all the test components.

3. Inspection rejection standards are clearly established in both the DAQ “North Carolina Analyzer System Specification,” and the DMV “Safety and Emissions Regulation Manual.”



## I. TEST EQUIPMENT (40 CFR §51.358)

1. Test equipment specifications are contained in the DAQ “North Carolina Analyzer System Specification.” The DMV regulations manual contain equipment required to carry out inspections, “DMV License and Theft Policy and Procedures Manual.”

2. All test equipment is fully computerized and all processes are automated to the highest degree possible. The DMV law enforcement agents have the authority to clear lock-outs. Manufacturer’s service representatives are able to clear specific lockouts. The date and cause

North Carolina I/M SIP May 21, 2010 8of any occurrence of a lockout as well as the da te and the authority personnel who cleared the lockout are recorded in a data record.

Data entry functions associated with the test are streamlined through the use of look-up tables. To reduce data entry errors, vehicl e identification information requires redundant entry if manually entered. However, under normal circumstances, vehicle information entry is by bar code scanners. Emissions test results are recorded automatically by the analyzer.

3. The test process is completely controlled by the analyzer. The process begins with data entry of the vehicle registration, license plate and vehicle identification number (VIN) information. Verification of vehicle identification data is c onfirmed through re-entry of this information during the inspection. The test procedure se quence and pass/fail determinations are made automatically by the analyzer. Data is re corded to both a removable device (floppy/USB storage key) and a hard drive. Test data is sent via modem to the State during each inspection, and stored on the analyzer hard drive for a minimum of 60 days. Once transmitted to the State, it is maintained by the Vehicle Information Database (VID) contractor as a permanent data set. Prior to being loaded to the program database all information is edit checked for errors.



## J. QUALITY CONTROL (40 CFR §51.359)

1. Quality control procedures and record keepi ng requirements have been established in the “DMV License and Theft Policy and Procedures Manual.” These measures will ensure the State of North Carolina meets its commitment to provide motorists with consistent and accurate test results. The inspection site personne l must continue to ensure that all equipment is properly maintained and has updated vendor software.

2. The DAQ “North Carolina Analyzer System Specification” includes the minimum durability and functional requirements to ensure accurate processing and recording of test results. All enhancements and/or changes to this document are reviewed and approved prior to its release.



## K. WAIVERS AND COMPLIANCE VIA DIAGNOSTIC INSPECTION (40 CFR §51.360)

1. A waiver rate of 5% (percentage of initially failed vehicles receiving waivers) is assumed in the demonstration that the I/M program meets the basic performance standard. The State of North Carolina commits to a waiver rate in practi ce that is equal to or lower than 5%. If the waiver rate reported in the annual report to EPA is higher, the State will take corrective action to lower the waiver rate. Corrective strate gies may include: not issuing waivers on vehicles under 6 years of age, raising minimum expenditu re limits, and limiting waivers on vehicles to only 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 implemen t measures to do so, the State will revise the I/M emission reduction projections in the SIP and will implement other program changes needed to ensure the performance standard is met.

2. The State of North Carolina commits to issui ng waivers only when the requirements of the 40 CFR §51.360 are met. §51.360 requires a minimum of $200 for 1981 and newer vehicles be spent in order to qualify for a waiver. Repa irs must be performed by a recognized repair

North Carolina I/M SIP May 21, 2010 9technician to apply toward the waiver limit. Waivers are issued by DMV as outlined in the

“ DMV License and Theft Policy and Procedures Manual” and authorized by NCGS § 20-183.5A. “When a vehicle that fails a sa fety inspection because of missing emissions control devices may obtain a waiver.”

3. EPA regulations allow a time extension to obtai n needed repairs on a vehicle in the case of economic hardship when waiver requirements have not been met. The DMV, at this time, has not chosen to offer time extensions.

EPA regulations also allow exemptions for tamper ing-related repairs if it can be verified that the part in question or one similar to it is no longer available for sale. The DMV has chosen to offer tamper-related exemptions; DMV will verify that the part in question or one similar to it is no longer available for sale prior to issuing the exception.

4. The emissions receipt (certificate) for a failed vehicle inspection alerts the motorist of emission failure information, warranty cove rage, and waiver availability in the DAQ’s “North Carolina Analyzer System Specification.”



## L. MOTORIST COMPLIANCE EN FORCEMENT (40 CFR §51.361)

1. The legal authority for the implementation of the I/M program is included in § 143-215.107. “Air quality standards and classifications.” The regulations governing specific operation of this aspect of the program are contained in the regulations in 15A NCAC 02D .1005, “OnBoard Diagnostic Standards.”

2. The legal authority for enforcement of the I/M program is included in, NCGS § 20-183.8. “Infractions and criminal offenses for violations of inspection requirements.” A penalty schedule for violations of these regulations is included in NCGS Article 3A – Safety and Emissions Inspection Program § 20-183.8A

, “Civil penalties against motorists for emissions violations; waiver.”

3. A registration-denial based program is used for enforcement. As of April 12, 2010, vehicles will be denied registration renewal if a require d emissions inspection is not found in the VID for that vehicle. Vehicle owners are allowed 90 days prior to the registration expiration date to get an inspection for their vehicle.

The DMV developed the “DMV License and Theft Policy and Procedures Manual” to be followed by personnel involved in enforci ng and overseeing the program. This manual details the procedures followed by the DMV and other State personnel involved in I/M program document handling and processing a nd by the supervisory personnel who oversee staff involved in program enforcement, docum ent handling and processing. The procedures manual also provides a schedule of disciplinary actions used against personnel who deviate from prescribed procedures.

4. All non-gasoline powered vehicles, motorcycles, heavy-duty, and current model year vehicles are exempt from the I/M program.

5. There are no provisions for off-hours testing for fleet vehicles since fleets may be selfinspected. Fleets may be officially inspected outside of the normal I/M program test

North Carolina I/M SIP May 21, 2010 10facilities, but are subject to the same test requirements using the same quality control standards as non-fleet vehicles.

6. The State of North Carolina commits to the level of motorist enforcement necessary to ensure a compliance rate of no less than 92% among subj ect vehicles by 2011. This compliance rate reflects the compliance rate used in the de monstration of the performance standard as described in Section A of this document

. If it is determined that the I/M program is not meeting the compliance rate committed to here, the DAQ will review the compliance methodology and revise when necessary. The DAQ believes that the compliance rate of 92% is a conservative estimate. However, when the new electronic authorization program is fully implemented, the DAQ and DMV anticipate compliance rates to considerably improve.



## M. MOTORIST COMPLIANCE ENFORCEMENT PROGRAM OVERSIGHT (40 CFR §51.362)

1. The “DMV License and Theft Policy and Procedures Manual” details the procedures followed by the DMV in enforcing the moto rist compliance portion of the I/M program, handling and processing program documents, a nd by the supervisory personnel who oversee staff involved in program enforcement, doc ument handling, and processing. The State Personnel Manual describes disciplinary actions to be used against personnel who deviate from prescribed procedures.



## N. QUALITY ASSURANCE (40 CFR §51.363)

1. The DMV uses a process to automate their repor ting system that gathers information of the DMV’s activities that takes place across the state. In mid-2006, the DMV began the installation of their new enforcement appli cation package that tracks all enforcement activities and field auditing activities in an electronic format for better efficiency. Verizon Business, the VID contractor developed a new real time data collection system called the North Carolina Electronic Transmission System (NCETS). NCETS helps to improve the DMV’s remote auditing of stations, by allowing the DMV field staff to remotely observe an inspection taking place from their computer. NCETS also allows authorized station personnel to purchase electronic authorizations for their analyzers.

2. The DMV schedules a minimum of four overt a udits per station per year, and one covert audit per station per year and as many remote observations as required to validate complaints or concerns of wrong doing. The DMV a nd DAQ requested approval from EPA to reduce the number of covert audits from two to one per year, while the DMV implements a new targeted enforcement program. Details of this new effort is outlined in the DAQ’s “Inspection and Maintenance (I/M) Program Audit Procedure Manual” and the “DMV License and Theft Policy and Procedures Manual.”

3. All DMV program auditors shall themselves be audited once per year by the DAQ. The DAQ “Inspection and Maintenance (I/M) Program Audit Procedure Manual” documents the

North Carolina I/M SIP May 21, 2010 11procedures the DAQ follows while auditing th e I/M program and the DMV quality assurance
auditors.



## O. ENFORCMENT AGAINST CONT RACTORS, STATIONS AND INSPECTORS (40 CFR §51.364)

1. The DMV is responsible for enforcement against inspection stations and inspector mechanics. The enforcement actions that the DMV must follow for violations found at inspection stations or by inspectors are outlined in the following statutes:

• NCGS § 20-183.8, “Infract ions and criminal offenses for violations of inspection requirements”

• NCGS § 20-183.8A, “Civil penalties against motorists for emissions violations; waiver”

• NCGS §20-183.8B, “Civil penalties against license holders and suspension or revocation of license for emissions violations”

• NCGS § 20-183.8C “Acts that are Type I, II, or III emissions violations”

• NCGS § 20-183.8D, “Suspensi on or revocation of license.”

• NCGS § 20-183.8F, “Requirements for giving license holders notice of violations and for taking summary action.” The NCGS allow for the immediate suspension or revocation of a license when a violation is found at an inspection station or by an inspector.

2. The administrative and judicial procedures a nd responsibilities relevant to the enforcement process are outlined in, NCGS § 20-183.8G, “Administrative and judicial review.”



## P. DATA COLLECTION (40 CFR §51.365)

1. The DAQ’s “North Carolina Analyzer System Specification” contains the equipment specifications that must be met by all I/M tes ting equipment approved for use in the State of North Carolina. This manual also provides da ta collection requirements and record storage formatting for the analyzers. The information contained within each vehicle test record is such that it is possible to tie specific test results to a specific vehicle, test site, analyzer, and inspector. 2. The State of North Carolina hereby commits to gather, summarize and report the results of quality control checks performed on testing equipment, sorted according to station number, analyzer number, date, and the start time of the quality control check.



## Q. DATA ANALYSIS AND RE PORTING (40 CFR §51.366)

1. Annually, the State of North Carolina will ge nerate a report summary based upon program data collected from January through December of the previous year. This report will provide statistics for the testing program, the qualit y control program, the quality assurance program, and the enforcement program. At a minimum, the State commits to address all of the data elements listed in 40 CFR §51.366

.

North Carolina I/M SIP May 21, 2010 122. The State of North Carolina shall report bienni ally on all changes made in the program design, funding, personnel levels, procedures, regulations, and legal authority, and shall supply a detailed discussion of the impact of such changes upon the program. This report will also detail and discuss any weaknesses or problems discovered in the program over the previous two-year period, as well as the steps th at were taken to address those problems, the result of those corrective actions, and any future efforts planned.



## R. INSPECTOR TRAINING AND LICE NSING OR CERTIFICATION (40 CFR §51.367)

1. Inspectors are required to successfully complete an eight-hour course approved by the DMV that teaches students about the causes and effects of the air pollution problem, the purpose of the emissions inspection program, the vehicle emission standards established by the EPA, the emission control devices on vehicles, how to conduct an emissions inspection using equipment to analyze data provided by the OBD equipment approved by the EMC, and any other topic required by 40 C.F.R. § 51.367 to be included in the course. This course is offered at local community colleges across the state. Successful course completion requires a passing score on a written test and on a hands-on test in which the st udent is required to conduct an emissions inspection of a motor vehicle.

2. By law, NCGS § 20-183.4, “License requi red to perform emissions inspection; qualifications for license” , both stations and inspectors are required to apply for a license with the DMV. Stations are also required to have equipment to analyze data provided by the OBD equipment approved by the EMC.



## S. PUBLIC INFORMATION AND COSUMER PROTECTION (40 CFR §51.368)

1. The DAQ and DMV have a Memorandum of U nderstanding to jointly address public outreach for the OBD I/M program throughout the life of the program. Both agencies have developed public service announcements that inform the public about the I/M program. When the OBD program first started in No rth Carolina, many of the public service announcements focused on informing the public about the new program and when it would become effective in the various areas across the State. Additionally, Car Care Clinics were held across the State, which provided face-to-fa ce time with the public and the inspection facilities to discuss the importance of the I/M pr ogram. Open-Net Forums were broadcasted on public television four or five times a year , in both English and Spanish, which provided the public the opportunity to call into the show and have their questions answered about the I/M program. Finally, the DAQ has established a separate web page (http://daq.state.nc.us/motor/inspect/htdocs/en/) providing information on the I/M program.

Now that the program has been fully implem ented, the public service announcements have focused on the importance of vehicle maintenance.

In addition to the OBD specific outreach, the DAQ has an Air Awareness program that provides general public education and outreach acr oss the State about air quality issues. This program has two state-wide coordinators and he lps fund local coordinators in several areas

North Carolina I/M SIP May 21, 2010 13North Carolina I/M SIP May 21, 2010 14 across the State to educate the public about how their actions impact the air quality and types of things the public may do to minimize thei r emissions. Since highway mobile sources are the largest source of emissions contributed to the general public, part of the Air Awareness program focuses on educating the public about the OBD I/M program, what the check engine light means, and why it is important to keep their vehicles maintained.

Additionally, the DAQ voluntar ily provides Air Quality Forecasts across the State. Currently, the DAQ forecasts for ozone and fine particulate matter in the following areas: Asheville (both valley and ridge tops), Hic kory, Charlotte/Gastonia, Greensboro/WinstonSalem/High Point, Raleigh/Durham/Chapel H ill, Fayetteville and Rocky Mount (no PM forecast due to no continuous monitor in the area). The forecasts are available through the DAQ website, a toll-free hotline, the EPA Air Now website, the newspapers and the broadcast media. In addition to the Air Qua lity Forecasts, real-time ambient air quality data can be viewed on the DAQ website or the public may call a hotline that provides the current Air Quality Index for nine areas in the State.

2. The DMV has made provisions for individuals wishing to challenge their results from an I/M station. When a vehicle fails an emissions test, the test report automatically includes information concerning causes for emissions failure , vehicle warranty, and waiver availability as outlined in the DAQ’s “North Carolina Analyzer System Specification.”



## T. IMPROVING REPAIR EFFECT IV ENESS (40 CFR §51.369)

1. North Carolina’s basic I/M program is not requi red to track repair effectiveness of individual repair facilities, however the DAQ has develope d a course curriculum (basic and advanced) for the diagnosis and repair of motor vehicles that have OBD systems and has provided training sessions for community college instructor s to offer this specialized training.



## U. COMPLIANCE WITH RECALL NOTICES (40 CFR §51.370)

1. Although not required for basic I/M program, the North Carolina emi ssions analyzers will display emissions related Technical Service Bulletins (TSB) or recall information, if available from the VID, during the emission inspection process.



## V. ON ROAD TESTIN G (40 CFR §51.371)

1. On-road testing is not required of North Carolina’s basic I/M program.

## APPENDIX 2 MOBILE Modeling Assumptions

## MOBILE6.2 Modeling Results

MOBILE6.2 model runs to demonstrate complian ce for the 1997 8-hour ozone standards. Since Mecklenburg and Gaston Counties were 1-hour ozone maintenance areas, the performance standards for these two counties were slightly different from the remaining counties in the 1997 8-hour ozone nonattainment area (Cabarrus, Li ncoln, Rowan, Union Counties and Coddle Creek and Davidson Townships in Iredell County). Below are the emission factors for the two performance standards that are required to be met and the pr ogram target based upon how North Carolina’s Inspection and Maintenance (I/M) pr ogram is actual run. The North Carolina I/M program meets the emission reduc tion targets in the attainment year. The State of North Carolina commits to meeting the performance standard.

Emission Factors for Mecklenburg and Gaston Counties (grams/mile)

VOC NOx

Performance Standard 0.784 0.750

Program Target 0.726 0.688

Emission Factors for Remaining Counties (grams/mile)

VOC NOx

Performance Standard 1.363 1.027

Program Target 1.280 0.936

## MOBILE6.2 Modeling Assumptions

Modeled Calendar Year:

• As required by the Code of Federal Regul ations (CFR) 40 CFR 51.352(e) the evaluation date is to be set at six years after the effective date of designation. The CharlotteGastonia-Rock Hill, North Carolina-South Carolina Moderate Nonattainment area (referred to as the Metrolin a area) has an effective de signated date of June 15, 2004, therefore, the evalua tion date is 2010.

I/M Program Start Year:

• Performance Standards for Mecklenburg a nd Gaston Counties: According to 51.352(c), the required start date wa s 2002, with the idle test fo r 1968 to 1995 vehicles and On Board Diagnostic II (OBD) fo r 1996 and newer vehicles.

• Program Target for Mecklenburg and Gaston Counties: Although these two counties had the idle test implemented in prior to 2002, the OBD I/M program was implemented in these two counties starting July 2002 for all 1996 and newer vehicles. By the evaluation year (2010), the idle test had been phased-out and only the OBD test was required. Therefore, the I/M program start year fo r Mecklenburg and Gaston Counties was set at 2003.

• Performance Standards for Remaining Countie s: According to 51.352(e), the required start date was 2008, with the id le test for 1968 to 2000 vehicles and On Board Diagnostic II (OBD) for 2001 and newer vehicles.

• Program Target for Cabarrus and Union Counties: Although these two counties had the idle test implemented in prior to 2002, th e OBD I/M program was implemented in these two counties starting July 2002 for all 1996 and newer vehicles. By the evaluation year (2010), the idle test had been phased-out and on ly the OBD test was required. Therefore, the I/M program start year for Cabarr us and Union Counties was set at 2003.

• Program Target for Iredell, Lincoln and Ro wan Counties: The OBD I/M program, for all 1996 and newer vehicles, was implemented in Iredell and Rowan C ounties starting July 2003 and in Lincoln County star ting January 2004. Therefore, the I/M program start year for Cabarrus and Union Counties was set at 2003.

Anti-Tampering Program:

• North Carolina began a statewide safety inspection program in 1975. This program includes checking the vehicle for tampering of emission control equipment. Vehicles 35 years old and newe r are inspected.

Vehicle Registra tion and VMT mix:

• North Carolina Division of Air Quality (NCDAQ ) receives vehicle registration data for Mecklenburg and Gaston Counties combined and for the remaining counties in that nonattainment area uses the statewide ve hicle registration data. The 2008 vehicle registration data, the most rece nt data available, was used for these runs. The vehicle registration data is attached at the end of this summary.

### • The VMT mix was based on the latest data ava ilable from the transportation partners and is presented below.

0.3751 0.0939 0.3127 0.0963 0.0443 0.0388 0.0037 0.0031 0.0024 0.0086 0.0021 0.0023 0.0082 0.0019 0.0010 0.0056

Vehicle Speeds:

• To minimize the number of runs as recomm ended by the United States Environmental Protection Agency (USEPA), one vehicle sp eed of 24 miles per hour was used for all

runs.
Reid Vapor Pressure:

• For Mecklenburg and Gaston Counties, the Re id Vapor Pressure (RVP) is 7.8 pounds per square inch (psi) during the summer months as required by 40 CFR 80.27.

• For the remaining nonattainment counties, th e RVP is 9.0 psi during the summer months.

Temperature, Relative Humidity and Barometric Pressure:

• The temperature, relative humidity and barometric pressure used in these modeling runs were the same data used in the latest attain ment demonstration plan. This data was based on average July 2002 data for the Metrolina region.

• The hourly temperature data as formatted in the input files:

71.0 73.8 77.0 80.3 82.5 85.4 87.3 88.5 89.1 88.5 89.6 89.2 86.3 82.6 77.8 77.5 76.2 75.9 75.0 74.0 73.2 82.3 71.6 71.0

• The hourly relative humidity data as formatted in the input files:

91. 86. 78. 71. 65. 59. 53. 50. 48. 51. 47. 47. 53. 61. 70. 71. 76. 77. 79. 83. 85. 87. 88. 91.

• The barometric pressure is set to 30 inches of mercury, which is consistent with the average summertime barometric pressure in North Carolina.

Altitude:

• North Carolina is considered a low a ltitude region for modeling purposes.
