Approval and Promulgation of Air Quality Implementation Plans; 
Virginia; Enhanced Motor Vehicle Inspection and Maintenance Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed interim rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing conditional, interim approval of a State 
Implementation Plan (SIP) revision submitted by the Commonwealth of 
Virginia. This revision establishes and requires the implementation of 
an enhanced inspection and maintenance (I/M) program in the following 
Northern Virginia localities: the Counties of Arlington, Fairfax, 
Fauquier, Loudoun, Prince William, and Stafford, and the Cities of 
Alexandria, Fairfax, Falls Church, Manassas, and Manassas Park.
    The intended effect of this action is to propose conditional 
interim approval of the enhanced I/M program proposed by Virginia for 
the Northern Virginia program area, based upon the Commonwealth's good 
faith estimate that the proposed test-and-repair network design is 
appropriate and will achieve the expected emissions reductions and that 
the revision is otherwise in compliance with the Clean Air Act (CAA). 
EPA is proposing conditional approval because the Commonwealth's SIP 
revision is deficient with respect to certain requirements of the CAA 
and/or EPA's I/M program regulatory requirements.

DATES: Comments must be received on or before December 6, 1996.

SUPPLEMENTARY INFORMATION:

I. Background

A. Impact of the National Highway System Designation Act on the Design 
and Implementation of Enhanced Inspection and Maintenance Programs 
under the Clean Air Act

    The National Highway System Designation Act of 1995 (NHSDA) 
establishes two key changes to the enhanced I/M rule requirements 
previously developed by EPA. Under the NHSDA, EPA cannot require states 
to adopt or implement centralized, test-only IM240 enhanced vehicle 
inspection and maintenance programs as a means of compliance with 
section 182, 184 or 187 of the CAA. Also under the NHSDA, EPA cannot 
disapprove a state SIP revision, nor apply an automatic discount to a 
state SIP revision under section 182, 184 or 187 of the CAA, because 
the I/M program in such plan revision is decentralized, or a test-and-
repair program. Accordingly, the so-called ``50% credit discount'' that 
was established by the EPA's I/M Program Requirements Final Rule, 
(published November 5, 1992, and herein referred to as the I/M rule) 
has been effectively replaced with a presumptive equivalency criteria, 
which places the emission reductions credits for decentralized networks 
on par with credit assumptions for centralized networks, based upon a 
state's good faith estimate of reductions as provided by the NHSDA and 
explained below in this section.
    EPA's I/M rule established many other criteria unrelated to network 
design or test type for states to use in designing enhanced I/M 
programs. All other elements of the I/M Rule, and the statutory 
requirements established in the CAA continue to be required of those 
states submitting I/M SIP revisions under the NHSDA, and the NHSDA 
specifically requires that these submittals must otherwise comply in 
all respects with the I/M Rule and the CAA.
    The NHSDA also requires states to swiftly develop, submit, and 
begin implementation of these enhanced I/M programs, since the 
anticipated start-up dates developed under the CAA and EPA's rules have 
already been delayed. In requiring states to submit these plans within 
120 days of the NHSDA passage, and in allowing these states to submit 
proposed regulations for this plan (which can be finalized and 
submitted to EPA during the interim period) it is clear that Congress 
intended for states to begin testing vehicles as soon as practicable, 
now that the decentralized credit issue has been clarified and directly 
addressed by the NHSDA.
    Submission criteria described under the NHSDA allows for a state to 
submit proposed regulations for this interim program, provided that the 
state has all of the statutory authority necessary to carry out the 
program. Also, in proposing the interim credits for this program, 
states are required to make good faith estimates regarding the 
performance of their enhanced I/M program. Since these estimates are 
expected to be difficult to quantify, the state need only provide that 
the proposed credits claimed for the submission have a basis in fact. A 
good faith estimate of a state's program may be an estimate that is 
based on any of the following: the performance of any previous I/M 
program; the results of remote sensing or other roadside testing 
techniques; fleet and vehicle miles traveled (VMT) profiles; 
demographic studies; or other evidence which has relevance to the 
effectiveness or emissions reducing capabilities of an I/M program.
    This action is being taken under the authority of both the NHSDA 
and section 110 of the CAA. Section 348 of the NHSDA expressly directs 
EPA to issue this interim approval for a period of eighteen months, at 
which time the interim program will be evaluated in concert with the 
appropriate state agencies and EPA. At that time, the Conference Report 
on section 348 of the NHSDA states that it is expected that the 
proposed credits claimed by the state in its submittal, and the 
emissions reductions demonstrated through the program data may not 
match exactly. Therefore, the Conference Report suggests that EPA use 
the program data to appropriately adjust these credits on a program 
basis as demonstrated by the program data.
    Furthermore, EPA believes that in also taking action under section 
110 of the CAA, it is appropriate to grant a conditional approval to 
this submittal since there are some deficiencies with respect to CAA 
statutory and regulatory requirements (identified herein) that EPA 
believes can be corrected by the state during the interim period.
    Finally, it should also be noted that Virginia has submitted a 
separate SIP revision addressing a ``basic'' I/M program requirement 
for the Richmond area. EPA is not acting upon that submittal in today's 
rulemaking action, and intends to act upon that submittal at a later 
date.

B. Interim Approvals Under the NHSDA

    The NHSDA directs EPA to grant interim approval for a period of 
eighteen months to approvable I/M submittals under this Act. This Act 
also directs EPA and the states to review the interim program results 
at the end of eighteen months, and to make a determination as to the 
effectiveness of the interim program. Following this demonstration, EPA 
will adjust any credit claims made by the state in its good faith 
effort to reflect the emissions reductions actually measured by the 
state during the program evaluation period. The NHSDA is clear that the 
interim approval shall last for only eighteen months, and that the 
program evaluation is due to EPA by the end of that period. Therefore, 
EPA believes Congress intended for these programs to start-up as soon 
as possible, which EPA believes should be on or before November 15, 
1997, so that at least 6 months of operational program data can be 
collected to evaluate the interim program. EPA believes that in setting 
such a strict timetable for program evaluations under the NHSDA, that 
Congress recognized and attempted to mitigate any further delay with 
the start-up of this program. For the purposes of this program, 
``start-up'' is defined as a fully operational program which has begun 
regular, mandatory inspections and repairs, using the final test 
strategy and covering each of a state's required areas. EPA proposes 
that if the state fails to start its program on this schedule, the 
approval granted under the provisions of the NHSDA will convert to a 
disapproval after a finding letter is sent to the state.
    The program evaluation to be used by the state during the 18-month 
interim period must be acceptable to EPA. EPA anticipates that such a 
program evaluation process will be developed by the Environmental 
Council of States (ECOS) group that is convening now and that was 
organized for this purpose. EPA further anticipates that in addition to 
the interim, short term evaluation, the state will conduct a long term, 
ongoing evaluation of the I/M program as required by the I/M Rule in 
Secs. 51.353 and 51.366.

[[Page 57345]]

C. Process for Full Approvals of This Program Under the CAA

    As per the NHSDA requirements, this interim rulemaking will expire 
within eighteen months of the final interim approval, or the date of 
final approval. A full approval of the state's final I/M SIP revision 
(which will include the state's program evaluation and final adopted 
state regulations) is still necessary under section 110 and under 
section 182, 184 or 187 of the CAA. After EPA reviews the 
Commonwealth's submitted program evaluation, final rulemaking on the 
state's SIP revision will occur.

II. EPA's Analysis of Virginia's Submittal

    On March 27, 1996, the Virginia Department of Environmental Quality 
(DEQ) submitted a revision to its State Implementation Plan (SIP) for 
an enhanced I/M program to qualify under the NHSDA. That revision 
consists of enabling legislation that will allow the state to implement 
the I/M program, proposed regulations, a description of the I/M program 
(including a modeling analysis and detailed description of program 
features), and a good faith estimate that includes the state's basis in 
fact for emission reductions claims of the program. The state's credit 
assumptions are based upon the removal of the 50% credit discount for 
all portions of the program that are based on a test-and-repair 
network, and the application of the state's own estimate of the 
effectiveness of its decentralized test and repair program.

A. Analysis of the NHA submittal criteria

Transmittal Letter
    On March 27, 1996, Virginia submitted an enhanced I/M SIP revision 
to EPA, requesting approval action under the NHSDA of 1995 and the CAA 
of 1990. The official submittal was made by the appropriate state 
official, Peter W. Schmidt, Director of the Department of Environmental 
Quality, and was addressed to the appropriate EPA official in the 
Region.
Enabling Legislation
    The Commonwealth of Virginia has enabling legislation at the Motor 
Vehicle Emissions Control Law at Title 46.2, Subtitle III, Chapter 10, 
Article 22 of the Code of Virginia. This legislation provides for the 
implementation of a decentralized, test-and-repair program network 
utilizing ASM 5015 testing equipment, with testing on a biennial basis.
Proposed Regulations
    Prior to submitting its March 27, 1996 submittal, the Commonwealth 
of Virginia proposed regulations before its Air Pollution Control Board 
in accordance with 40 CFR Part 51, establishing an enhanced I/M 
program. The Commonwealth anticipates fully adopting regulations by 
October 30, 1996.
Program Description
    The Commonwealth's proposed enhanced I/M program applies to the 
Northern Virginia metropolitan area, and includes biennial testing of 
1968 and newer gasoline powered light-duty vehicles (LDGV) and light-
duty trucks (LDGT) up to 10,000 pounds gross vehicle weight rating 
(GVWR) in a fully test-and-repair network. Test methods are to include 
a two-mode acceleration simulation mode (ASM) exhaust emissions test as 
the primary test method for newer-technology (i.e. 1981 and newer) 
LDGVs. Two-speed idle testing will be performed on: LDGTs, older 
technology (i.e. pre-1981) LDGVs, and on any LDGV equipped with full-
time four wheel drive or full-time anti-lock brake systems. 
Additionally, evaporative system testing is to be performed, including 
an evaporative system pressure test for 1973 and newer vehicles, and an 
evaporative system purge test (for 1981 and newer vehicles which 
receive ASM testing). On 1973 and newer vehicles, a visual inspection 
for the presence of certain emissions control components or systems 
will eventually be performed. The following systems will be checked: 
the air injection system, catalytic converter system, fuel evaporative 
emissions control system, positive crankcase ventilation (PCV) system, 
exhaust gas recirculation (EGR) system, and the thermostatic air 
cleaner system. Finally, a fuel filler cap check for 1973 and newer 
vehicles is included. Motorists will be required to pass all aspects of 
emissions testing prior to re-registering their vehicles. On-road 
testing will be used to ensure that motorists comply with testing 
requirements and that vehicle emissions remain below pollution 
standards between biennial tests.
Emission Reduction Claim and Basis for the Claim
    As Virginia stated in the March 27, 1996 SIP submittal, the 
Commonwealth is claiming additional I/M program effectiveness for their 
test-and-repair network, when compared to EPA's assumed credit discount 
for this type of testing network. Virginia claims that its test-and-
repair network will be 93.8% as effective as an equivalent test-only 
network, in terms of hydrocarbon and oxides of nitrogen pollutant 
reductions. Per the recently enacted National Highway Systems 
Designation Act, the Commonwealth has 18 months from the date of EPA 
final interim approval of the March 27, 1996 SIP revision to obtain the 
data on operation of its program in order to prove its effectiveness 
claims.
    The Commonwealth's good faith estimate achieves credit through the 
following measures, which are part of the March 27, 1996 SIP submittal:
    1. A program effectiveness demonstration of the existing Northern 
Virginia I/M program, compiled in conjunction with EPA, entitled 
``Study to Demonstrate Increased Emissions Reduction Credit for the 
Northern Virginia Test-and-Repair Program'', dated December 21, 1995;
    2. A more stringent on-road testing program than required by 
federal requirements, through remote sensing and a civil penalty system 
for noncompliance;
    3. Implementation of a technician training and certification 
program and a repair facility certification program; and
    4. Improved data entry automation, including bar code readers at 
test stations to read bar-coded registration forms to eliminate data 
entry errors.

B. Analysis of the EPA I/M Regulation and CAA requirements

    As previously stated, the NHSDA left those elements of the I/M rule 
that do not pertain to network design or test type intact. Based upon 
EPA's review of Virginia's submittal, EPA believes the Commonwealth has 
not complied with all aspects of the NHSDA, the CAA and the I/M rule. 
For those sections of the I/M rule, or of the CAA, identified below, 
with which the state has not yet fully complied, EPA proposes to 
conditionally approve the SIP upon receipt of a commitment from the 
state to correct each said deficiency. Before EPA can continue with the 
interim rulemaking process, the Commonwealth must make a commitment 
within 30 days of November 6, 1996 to correct these major SIP 
element(s) by a date certain within 1 year of EPA interim approval.
    The Commonwealth must correct these major deficiencies by the date 
specified in the commitment, or this approval will convert to a 
disapproval under CAA section 110(k)(4). EPA has also identified 
certain minor deficiencies in the SIP, which are itemized below. EPA 
has determined that delayed correction of these minor deficiencies will 
have a de minimis

[[Page 57346]]

impact on a state's ability to meet clean air goals. Therefore, the 
state need not commit to correct these deficiencies in the short term, 
and EPA will not impose conditions on interim approval with respect to 
these deficiencies. Virginia must correct these deficiencies during the 
eighteen month term of the interim approval, as part of the fully 
adopted rules that the Commonwealth will submit to support full 
approval of its I/M SIP. So long as Virginia corrects these minor 
deficiencies prior to final action on the I/M SIP, EPA concludes that 
failure to correct these minor deficiencies in the short term will not 
adversely affect EPA's ability to give interim approval to the proposed 
I/M program.
Applicability--40 CFR 51.350
    Sections 182(c)(3) and 184(b)(1)(A) of the Act and 40 CFR 51.350(a) 
require states, or portions of states, located in the Ozone Transport 
Region (OTR), containing Metropolitan Statistical Areas (MSAs), or 
parts thereof, with a population of 100,000 or more (as of 1990) to 
implement an enhanced I/M program. The Northern Virginia portion of the 
Washington, D.C. MSA is part of the OTR and has a population of 100,000 
or more. This area is also classified as a serious ozone nonattainment 
area and would therefore be required to implement an enhanced I/M 
program, per section 182(c)(3) of the CAA and 40 CFR 51.350(2).
    Under the above Clean Air Act requirements, the following 
localities in Virginia are subject to the enhanced I/M program 
requirements: the Counties of Arlington, Fairfax, Loudoun, Prince 
William and Stafford; and the Cities of Alexandria, Fairfax, Falls 
Church, Manassas, and Manassas Park. Under the federal I/M rule, 
specifically 40 CFR 51.350(b), some rural counties having a population 
density of less than 200 persons per square mile based on the 1990 
census could be excluded from program coverage provided that at least 
50% of the MSA population is included in the program. No counties 
within the Northern Virginia MSA qualify for this low population 
density exemption, however. The Commonwealth's proposed I/M regulation, 
as submitted with the SIP, requires that the enhanced I/M program be 
implemented in the localities listed above, and also in Fauquier 
County.
    Virginia's I/M legislative authority provides the legal authority 
to establish the proposed geographic boundaries. The program boundaries 
are defined in Virginia's Regulation for the Control of Motor Vehicle 
Emissions, located at 9 VAC 5-91-20. That portion of the regulation 
defines the ``Northern Virginia Program Area'' to include the counties 
identified above. EPA is proposing to find that the geographic 
applicability requirements are satisfied. The federal I/M regulation 
requires that the state program shall not sunset until it is no longer 
necessary. EPA interprets the federal regulation as stating that a SIP 
which does not sunset prior to the attainment deadline for each 
applicable area satisfies this requirement. The Virginia I/M enabling 
legislation and regulation provides for the program to continue past 
the attainment dates for all enhanced I/M program areas in the 
Commonwealth.
    Virginia's SIP satisfies all the requirements related to 40 CFR 
51.350 and is therefore approvable.
Enhanced I/M Performance Standard--40 CFR 51.351
    The enhanced I/M program must be designed and implemented to meet 
or exceed a minimum performance standard, or ``model'' program design, 
on the basis of emission levels expressed in area-wide average grams 
per mile (gpm) for certain pollutants. The performance standard is 
established using local characteristics, such as vehicle mix and local 
fuel controls, and the following model I/M program parameters: network 
type, start date, test frequency, model year coverage, vehicle type 
coverage, exhaust emission test type, emission standards, emission 
control device, evaporative system function checks, stringency, waiver 
rate, compliance rate and evaluation date. The emission levels achieved 
by the state's program design shall be calculated using the most 
current version, at the time of submittal, of the EPA mobile source 
emission factor model. At the time Virginia submitted its SIP, the most 
current version was MOBILE5a. Subject localities shall meet the 
performance standard for the pollutants which necessitate the enhanced 
I/M requirements. In the case of ozone nonattainment areas, the 
performance standard must be met for both oxides of nitrogen (NOX) 
and hydrocarbons (HC). Thus, the Commonwealth's submittal must meet the 
enhanced I/M performance standard for HC and NOX in all subject I/
M areas in the Northern Virginia area.
    In enacting the NHSDA, Congress evidenced an intent to have states 
promptly implement I/M programs under interim approval status to gather 
the data necessary to support state claims of appropriate credit for 
alternative network design systems. By providing that such programs be 
submitted within four months of passage of the NHSDA, that EPA could 
approve I/M programs on an interim basis, solely upon proposed 
regulations, and that such approvals would last only for an 18-month 
period, it is clear that Congress anticipated both that these programs 
would start quickly and that EPA would act quickly to give them interim 
approval.
    The Virginia submittal includes the following program design 
parameters:

----------------------------------------------------------------------------------------------------------------

    Virginia's modeling also includes credit for a mandatory emissions 
repair technician training and certification (TTC) program in the 
Northern Virginia program area.
    In order to determine whether the proposed I/M program meets the 
enhanced performance standard, the Commonwealth needed to model its 
program to demonstrate that it had met the enhanced performance 
standard. Because of delayed I/M program start up and program 
reconfiguration, the existing modeling used by the state to demonstrate 
compliance with the performance standard is no longer accurate, as it 
is based on start up and phase-in of testing and cutpoints that do not 
reflect the current program configuration or start dates that the state 
will actually implement. Additionally, modeling must be performed to 
demonstrate compliance with the performance standard for all affected 
localities. Therefore, the Commonwealth must conduct new modeling to 
verify that the performance standard will in fact be met. For example, 
actual start dates corresponding to each test-type and cutpoints 
correct program start up dates should be included in the new modeling.
    EPA proposes that interim approval of Virginia's I/M SIP be 
conditioned, in part, upon the requirement that the state conduct and 
submit the necessary new modeling to demonstrate that the program will 
meet the performance standard, by a fixed date within one year from 
final interim approval. In order to facilitate conditional approval of 
the Virginia SIP, Virginia must submit to EPA a commitment, within 30 
days of publication of this notice, to perform this modeling within the 
time frame set forth above. If the state fails to commit to perform 
this re-modeling, EPA proposed in the alternative to disapprove the 
SIP. If the state fails to perform and submit the new modeling by the 
date committed to, EPA proposes that the interim approval will convert 
to a disapproval upon a letter from EPA indicating that the state has 
failed to meet the conditions of approval by failing to timely submit 
the modeling and to demonstrate compliance with the performance 
standard.
Network Type and Program Evaluation--40 CFR 51.353
    The enhanced program shall include an ongoing evaluation to 
quantify the emission reduction benefits of the program, and to 
determine if the program is meeting the requirements of the Act and the 
federal I/M rule. The SIP shall include details on the program 
evaluation and shall include a schedule for submittal of biennial 
evaluation reports, data from state monitored or administered mass-
based, transient emissions testing of at least 0.1% of the vehicles 
subject to inspection each year, a description of the sampling 
methodology, the data collection and analysis system, and the legal 
authority enabling the evaluation program. Virginia's SIP provides for 
a decentralized, test-and-repair network design, which will be operated 
in multiple private inspection stations. Testing will be required on a 
biennial basis.
    In addition, the federal I/M rule requires the state to demonstrate 
that the program meets the performance standard by fixed evaluation 
dates. The first such date is January 1, 2000. However, few state 
programs will be able to meet the performance standard by then, as a 
result of delays in program start-up and the phased-in nature of 
various testing requirements. EPA believes that based on the provisions 
of the NHSDA, the evaluation dates in the current I/M rule have been 
superseded. Congress provided in the NHSDA for state development of I/M 
programs that would start significantly later than the start dates in 
the current I/M rule. Consistent with Congress's intent exhibited in 
the NHSDA with regard to program start-up, such programs by definition 
will not achieve full compliance with the regulatory performance 
standard by the beginning of the year 2000.
    Therefore, EPA has concluded that the NHSDA superseded the start 
date requirements of the I/M rule, but that states should still be 
required to start their programs as soon as possible, which EPA has 
determined would be by no later than November 15, 1997. EPA now 
believes that pursuant to the NHSDA, the initial evaluation date should 
be January 1, 2002. This evaluation date will allow states to fully 
implement their I/M programs and to complete one cycle of testing at 
full cutpoints in order to demonstrate compliance with the performance 
standard.
    The Commonwealth's SIP contains a commitment to perform an ongoing 
program evaluation, consisting of administration or oversight of 
inspections by Department of Environmental Quality (DEQ) personnel of 
at least 0.1% of the annually subject vehicle population. EPA 
interprets this broad commitment to indicate that Virginia staff will 
merely oversee or conduct testing in actual test stations using state-
approved I/M test methods. This program evaluation does not comply with 
the evaluation protocol set forth by EPA in 40 CFR 51.353(c).
    The Environmental Council of States (ECOS) has formed a committee 
to develop an evaluation protocol to be used by states in order to 
evaluate overall program effectiveness. The ECOS group has agreed that 
states must follow the long term program evaluation defined in 40 CFR 
51.353. 40 CFR 51.353 requires that mass-emission based, transient 
testing (METT) be performed on 0.1% of the subject fleet each year. The 
submittal also fails to address other program evaluation elements 
specified in 40 CFR 51.353(b)(1) and (c), including a program 
evaluation schedule, a protocol for the evaluation testing, and a 
system for collection and analysis of program evaluation data.
    EPA, therefore, proposes to conditionally approve Virginia's SIP 
based on receiving the Commonwealth's commitment within 30 days to 
submit to EPA by a date certain within twelve months of the final 
interim ruling, the final Virginia I/M regulation which requires METT 
be performed on 0.1% of the subject fleet each year as per 40 CFR 
51.353(c)(3) and meets the program evaluation elements as specified in 
40 CFR 51.353(c). If this condition is not

[[Page 57348]]

met EPA will promptly issue a letter to the Commonwealth indicating 
that the conditional approval has been converted to a disapproval.
Adequate Tools and Resources--40 CFR 51.354
    The federal I/M rule requires the Commonwealth to demonstrate that 
adequate funding of the program is available. A portion of the test fee 
or separately assessed per vehicle fee shall be collected, placed in a 
dedicated fund and used to finance the program. Alternative funding 
approaches are acceptable if a state demonstrates that the level of 
funding can be maintained. Reliance upon funding from a state or local 
general fund is not acceptable, unless doing otherwise would be a 
violation of the state's constitution. The SIP shall include a detailed 
budget plan which describes the source of funds for personnel, program 
administration, program enforcement, and purchase of equipment. The SIP 
shall also detail the number of personnel dedicated to the quality 
assurance program, data analysis, program administration, enforcement, 
public education and assistance and other necessary functions.
    Virginia DEQ's I/M oversight program will be funded through a per 
vehicle I/M inspection fee, which is currently set at $20; along with a 
separate administrative registration fee of $2 per vehicle. The 
administrative fee will be deposited in a dedicated fund, to be used 
solely for program oversight.
    The SIP contains a detailed budget synopsis describing the 
personnel dedicated to the quality assurance program, program 
oversight, data collection and analysis, enforcement, public education, 
and other necessary functions. Virginia's SIP indicates that this level 
of personnel resources is adequate to properly oversee the program, and 
that private contract personnel may be utilized, as needed, for special 
program functions (e.g. temporary audit staff, on-road testing 
contractors, etc).
    The Virginia submittal meets the requirements for adequate tools 
and resources, as set forth in the federal I/M regulations. Therefore, 
this portion of Virginia's SIP is approvable.
Test Frequency and Convenience--40 CFR 51.355
    The enhanced I/M performance standard assumes an annual testing 
frequency; however, alternative schedules may be approved if the 
performance standard is achieved. The SIP shall describe the test year 
selection scheme, how the test frequency is integrated into the 
enforcement process and shall include the legal authority, regulations 
or contract provisions to implement and enforce the test frequency. The 
program shall be designed to provide convenient service to the motorist 
by ensuring short wait times, short driving distances and regular 
testing hours.
    Section 46.2-1177 of Virginia's Motor Vehicle Emissions Control Law 
and Virginia's proposed I/M regulation provide the legal authority to 
implement the program with a biennial testing frequency. Virginia's 
proposed enhanced I/M regulation provides for a biennial testing, with 
initial testing for new vehicles required two years after initial 
registration. The Commonwealth has submitted modeling to demonstrate 
this biennial program's equivalency to the performance standard. 
However, this modeling analysis did not fully satisfy the requirements 
of 40 CFR 51.351. Upon satisfaction of the re-modeling condition in 
today's rulemaking action pertaining to the requirements of 40 CFR 
51.351, Virginia will have satisfied the equivalency of their biennial 
testing scheme to the annual scheme contained in the model program.
    Virginia's SIP lacks a detailed description of how emissions 
testing is scheduled for subject vehicles and the test selection scheme 
for assigning testing under the biennial program. Additionally, the SIP 
does not describe how the test frequency will be integrated with the 
registration denial motorist enforcement process. These elements 
constitute a minor deficiency in Virginia's SIP, which must be 
corrected in the final I/M SIP revision submitted by the end of the 18-
month interim period. This portion of Virginia's SIP otherwise 
satisfies the requirements of 40 CFR 51.355, and is therefore 
approvable.
Vehicle Coverage--40 CFR 51.356
    The performance standard for enhanced I/M programs assumes coverage 
of all 1968 and later model year light duty vehicles and light duty 
trucks up to 8,500 pounds GVWR, and includes vehicles operating on all 
fuel types. Other levels of coverage may be approved if the necessary 
emission reductions are achieved. Vehicles registered or required to be 
registered within the I/M program area boundaries and fleets primarily 
operated within the I/M program area boundaries and belonging to the 
covered model years and vehicle classes comprise the subject vehicles. 
Fleets may be officially inspected outside of the normal I/M program 
test facilities, if such alternatives are approved by the program 
administration, but shall be subject to the same test requirements 
using the same quality control standards as non-fleet vehicles and 
shall be inspected in the same type of test network as other vehicles 
in the state, according to the requirements of 40 CFR 51.353(a). 
Vehicles which are operated on federal installations located within an 
I/M program area shall be tested, regardless of whether the vehicles 
are registered in the state or local I/M area.
    The I/M rule requires that the SIP shall include the legal 
authority or rule necessary to implement and enforce the vehicle 
coverage requirement, a detailed description of the number and types of 
vehicles to be covered by the program and a plan for how those vehicles 
are to be identified, including vehicles that are routinely operated in 
the area but not registered in the area. Additionally, the SIP must 
contain a description of any special testing exemptions, including the 
percentage and number of vehicles to be impacted by the exemption. Such 
exemptions shall be accounted for in the emissions reduction analysis.
    The Northern Virginia enhanced I/M program requires coverage of all 
1968 and newer, private or publicly owned, gasoline-powered vehicles up 
to 10,000 pounds gross vehicle weight rating (GVWR) which are 
registered or required to be registered in the I/M program area. 
Additionally, affected motor vehicles which are primarily operated on 
or commute to a state, local or federal government facility, are also 
subject to testing. As of the date of the SIP submittal, Virginia 
estimates that approximately 1.25 million vehicles will be subject to 
enhanced testing in the program area.
    Virginia's proposed regulation exempts the following vehicles: 
motorcycles, diesel-fueled vehicles, electric-powered vehicles, clean-
fueled vehicles (as defined by Sec. 46.2-2 and 46.2-100 of the Code of 
Virginia), and vehicles registered as antiques. Additionally, Virginia 
SIP provides that testing may be deferred for vehicles (up to four 
model years old) held for sale by licensed car dealers, for up to one 
year from the date of sale. Section 46.2-1178 of the Virginia Motor 
Vehicle Control Law authorizes testing for the vehicles covered by 
Virginia's regulation, and Sec. 46.2-1180 of the Motor Vehicle Control 
Law provides for the exemptions in the regulation, as listed above. 
This level of vehicle coverage is approvable, provided the performance 
standard can be demonstrated to have been met with this level of 
exemptions.
    Virginia's SIP requires fleet vehicles, both public and privately 
owned, to be

[[Page 57349]]

tested. Virginia's regulation allows fleet owners having 20 or more 
vehicles to self test, provided they are licensed to do so by the 
Commonwealth. These fleet testing stations are subject to the same 
testing procedures and the same quality control procedures as official 
public testing stations. The fleet testing program is approvable, as it 
meets the requirements of 40 CFR 51.356(a).
    Virginia has not fully accounted for all of its testing exceptions, 
as a percentage of the entire subject fleet, in the SIP. Any exceptions 
to testing requirements must be accounted for in the emissions 
reductions analysis. Virginia has committed to better account for the 
number of excepted vehicles after the program commences operation. 
Since the exceptions are not expected to comprise a significant portion 
of the subject fleet, this is considered by EPA to be a minor 
deficiency. The state must better estimate these exceptions and account 
for them in their performance standard modeling demonstration prior to 
the end of the 18-month interim approval period.
    This portion of Virginia's SIP otherwise satisfies the requirements 
of 40 CFR 51.356, and is approvable.
Test Procedures and Standards--40 CFR 51.357
    Written test procedures and pass/fail standards shall be 
established and followed for each model year and vehicle type included 
in the program. Test procedures and standards are detailed in 40 CFR 
51.357 and in the EPA documents entitled ``High-Tech I/M Test 
Procedures, Emission Standards, Quality Control Requirements, and 
Equipment Specifications'', EPA-AA-EPSD-IM-93-1, dated April 1994 and 
``Acceleration Simulation Mode Test Procedures, Emission Standards, 
Quality Control Requirements, and Equipment Specifications'', EPA-AA-
RSPD-IM-96-2, dated July 1996. The federal I/M rule also requires 
vehicles that have been altered from their original certified 
configuration (i.e. engine or fuel switching) to be subject to the 
requirements of section 51.357(d).
    For the Northern Virginia enhanced program, Virginia has proposed a 
two-mode acceleration simulation mode (ASM2) exhaust test as its 
primary test method for newer-technology (i.e. 1981 and newer) light-
duty vehicles. This test actually consists of two separate tests, 
referred to as ASM 5015 and ASM 2525. Two-speed idle testing will be 
performed on subject heavy-duty vehicles, older technology (i.e. pre-
1981) light-duty vehicles, and on vehicles with full-time four wheel 
drive or full-time anti-lock brake systems. Additionally, evaporative 
system testing consisting of pressure testing (for 1973 and newer 
vehicles) and purge testing (for 1981 and newer vehicles receiving ASM 
testing) are included in the SIP. Virginia's regulation also calls for 
a visual inspection for the presence, on 1973 and newer vehicles, of 
certain emissions control components or systems, including the: air 
injection system, catalytic converter system, fuel evaporative 
emissions control system, positive crankcase ventilation (PCV) system, 
exhaust gas recirculation (EGR) system, and the thermostatic air 
cleaner system. Finally, the SIP calls for a fuel filler cap check for 
1973 and newer vehicles.
    The Commonwealth's regulation requires vehicles that have been 
altered from the original certified configuration to which they were 
manufactured (i.e. vehicles in which the engine or fuel type has been 
switched) to be tested to their originally certified design.
    The Commonwealth's SIP does not contain detailed ASM2 test 
procedures that are acceptable to EPA. The Commonwealth's regulation 
incorporates by reference the appropriate section of the Code of 
Federal Regulations (CFR) for I/M test procedures for 2-speed idle 
testing and for evaporative pressure and purge testing. However, the 
Virginia SIP allows for possible alternative evaporative system tests 
to those referenced by the Commonwealth's regulation. No test 
procedures are specified for any alternative evaporative system test, 
with the exception of a fuel filler cap check procedure. In order for 
the Commonwealth to include alternative evaporative tests in the 
performance standard demonstration and to require testing with these 
tests, the SIP must contain EPA approved test procedures for such 
tests. The final SIP must include detailed, approvable test procedures 
for all test methods to be utilized in the enhanced I/M program.
    The SIP includes hydrocarbon (HC), carbon monoxide (CO), and oxide 
of nitrogen (NOX) pass/fail standards (or ``cutpoints'') for the 
ASM2 test for each subject model year and vehicle type. HC and CO 
cutpoints are provided in Virginia's regulation for the 2-speed idle 
test procedure for all subject model year and types of vehicles. 
Standards will be phased-in over one biennial testing cycle, with final 
standards to apply at that time. EPA must receive all test procedures, 
specifications and standards before EPA can proceed with a final 
interim rulemaking action. EPA recently (August, 1996) released ASM 
test procedures, specifications and standards. In light of the 
finalization of these standards, EPA expects the Commonwealth to submit 
its ASM test procedures, specifications and standards in the near 
future.
    If within 30 days of the proposed interim rulemaking, the 
Commonwealth submits to EPA a commitment to adopt approvable test 
procedures for its two-mode ASM test, accompanied by a draft procedures 
document or a revised proposed regulation referencing or containing 
approved procedures, then EPA proposes to conditionally approve this 
portion of the SIP. The Commonwealth's commitment must include a date 
certain (prior to the date by which testing is to commence), within 
twelve months of the final interim ruling, by which the final Virginia 
I/M regulation or test procedure document will be formally submitted. 
If within 30 days of the proposed interim ruling, the above submittal/
commitment requirement has not been met, then this notice proposes in 
the alternative to disapprove the Virginia I/M SIP. If the condition to 
submit the final regulation or test procedures document which 
incorporates an approvable ASM2 test procedure is not met by the date 
committed to by the Commonwealth from the final interim ruling, then 
EPA will promptly issue a letter to the Commonwealth indicating that 
the conditional approval has been converted to a disapproval.
    Finally, Virginia's regulation must require that retests conducted 
after the performance of repairs shall include the performance of all 
emissions tests and for all pollutants for which the vehicle was 
originally subject, not merely the test and pollutant for which the 
vehicle initially failed. This is a minor deficiency, and must be 
corrected prior to the end of the 18-month interim approval period.
Test Equipment--40 CFR 51.358
    Computerized test systems are required for performing any emission 
measurement on subject vehicles. The federal I/M rule requires that the 
state SIP submittal include written technical specifications for all 
test equipment used in the program. The specifications shall describe 
the emission analysis process, the necessary test equipment, the 
required features, and written acceptance testing criteria and 
procedures.
    The Commonwealth's submittal lacks written technical specifications 
for all test equipment to be used in the program. The Commonwealth's 
regulation incorporates by reference 40 CFR part 51, subpart S (i.e., 
the I/M program requirements rule) and 40 CFR

[[Page 57350]]

part 85, subpart W (i.e., emissions performance warranty short tests 
rule). However, the regulation does not specifically include or 
reference EPA approved I/M test equipment specifications. Neither, does 
the SIP does not contain specifications to address performance features 
and functional characteristics of the computerized test systems. The 
Commonwealth's rule does, however, require the use of computerized test 
systems.
    Virginia must submit written test equipment specifications for the 
ASM2 test equipment and 2-speed idle test equipment, as well as the 
specifications for the necessary pressure and purge, and fuel filler 
cap check equipment. In light of the recent release of ASM test 
equipment specifications, in August 1996, EPA expects that the 
Commonwealth will adopt final test specifications in the near term.
    If within 30 days of the proposed interim rulemaking, the 
Commonwealth submits to EPA a commitment to adopt approvable test 
equipment specifications for all the I/M test procedures contained in 
its regulation, accompanied by draft specifications documents or by a 
revised proposed regulation referencing or containing approved test 
equipment specifications, then EPA proposes to conditionally approve 
this portion of the SIP. The Commonwealth's commitment must include a 
date certain (prior to the date by which testing is to commence), 
within twelve months of the final interim ruling, by which the final 
Virginia I/M regulation or test equipment specifications documents will 
be formally submitted. If within 30 days of the proposed interim 
ruling, the above submittal/commitment requirement has not been met, 
then this notice proposes in the alternative to disapprove the Virginia 
I/M SIP. If the condition to submit the final regulation or test 
procedure document which incorporates approvable test equipment 
specifications is not met by the date certain within twelve months (by 
which the Commonwealth commits to submit final test procedures) from 
the final interim ruling, EPA will promptly issue a letter to the 
Commonwealth indicating that the conditional approval has been 
converted to a disapproval.
Quality Control--40 CFR 51.359
    Quality control measures shall insure that emission measurement 
equipment is calibrated and maintained properly, and that inspection, 
calibration records, and control charts are accurately created, 
recorded and maintained. The Virginia submittal lacks a description of 
quality control measures for the emission measurement equipment, record 
keeping requirements and measures to maintain the security of all 
documents used to establish compliance with the inspection 
requirements.
    Virginia has committed in its SIP to develop and submit to EPA 
quality control procedures to ensure that the Commonwealth provides its 
motorists with accurate emissions test results. Some aspects of record 
keeping and document security are addressed in Virginia's regulation. 
However, the SIP presently does not satisfy quality control 
requirements.
    This is considered a minor deficiency, which must be corrected 
prior to expiration of the 18-month interim approval period. Virginia 
must develop quality control procedures, to be addressed within the 
Commonwealth's I/M regulation, test equipment specifications, quality 
control procedures manual, or other ordinance or documents to satisfy 
all the quality control requirements of 40 CFR 51.359.
Waivers and Compliance Via Diagnostic Inspection--40 CFR 51.360
    The federal I/M rule allows for the issuance of a waiver, which is 
a form of compliance with the program requirements that allows a 
motorist to comply without meeting the applicable test standards. For 
enhanced I/M programs, an expenditure of at least $450 in repairs, 
adjusted annually to reflect the change in the Consumer Price Index 
(CPI) as compared to the CPI for 1989, is required in order to qualify 
for a waiver. EPA recently amended the I/M rule to allow waivers to be 
phased-in after commencement of testing, but no later than January 1, 
1998 and to allow repairs conducted by recognized repair technicians up 
to 60 days prior to testing to apply towards the waiver expenditures.
    Waivers may only be issued after a vehicle has failed a retest 
performed after all qualifying repairs have been made. Any available 
warranty coverage must be used to obtain repairs before expenditures 
can be counted toward the cost limit. Tampering related repairs shall 
not be applied toward the cost limit. Repairs must be appropriate to 
the cause of the test failure. Repairs for 1980 and newer model year 
vehicles must be performed by a recognized repair technician. The 
federal regulation provides states the option to allow for compliance 
via a diagnostic inspection after failing a retest on emissions and 
requires quality control of waiver issuance. The SIP must set a maximum 
waiver rate and must describe corrective action that would be taken if 
the waiver rate exceeds that committed to in the SIP.
    Virginia's Motor Vehicle Emissions Control Law and the 
Commonwealth's proposed I/M regulation provide the necessary authority 
to issue waivers, set and adjust cost limits, administer and enforce 
the waiver system, and to set a $450 waiver cost limit (adjusted 
annually by the CPI, as compared to the CPI in 1989).
    Virginia's regulation phases in the waiver limits, beginning with 
the commencement of testing, over one biennial test cycle, to the 
federal limit by July 1, 1998. EPA is approving this phase-in schedule, 
because the commencement of I/M testing was delayed by the deadlines 
set forth in the NHSDA. EPA contends that this is consistent with its 
interpretation that start dates and evaluation dates may be extended by 
approximately two years under authority of the NHSDA, and phasing in 
the waiver over a similar time period is appropriate. Also, EPA's I/M 
rule provides one cycle to phase in the waiver after the start of 
testing, so it is acceptable for Virginia to phase in the waiver over 
one cycle after the start date set forth by the NHSDA.
    The Commonwealth's proposed regulation allows emission inspection 
station inspectors to issue waivers. The I/M rule, 40 CFR 51.360(c)(1), 
only allows the state or a single contractor to issue waivers. This is 
a minor deficiency and must be corrected in the final I/M SIP revision 
submitted by the end of the 18-month interim period.
    The Commonwealth has set a 3% maximum waiver rate, as a percentage 
of failed vehicles, for both pre-1981 and 1981 and later vehicles. The 
Commonwealth has committed, per 40 CFR 51.360, to take corrective 
action if the waiver rate exceeds 3%. This waiver rate was used in the 
Commonwealth's existing performance standard modeling demonstration, 
and should be maintained in the new performance standard modeling 
demonstration.
    Otherwise, the Commonwealth's SIP satisfies the waiver requirements 
of 40 CFR 51.360, and is approvable.
Motorist Compliance Enforcement--40 CFR 51.361
    The federal I/M rule requires that compliance be ensured through 
the denial of motor vehicle registration in enhanced I/M programs, 
unless an exception for use of an existing alternative is approved. The 
SIP shall provide information concerning the enforcement process, legal 
authority to implement and enforce the program, and a commitment to a 
compliance rate

[[Page 57351]]

to be used for modeling purposes and to be maintained in practice.
    Chapter 10, Sec. 46.2-1183 of the Motor Vehicle Emissions Control 
Law provides the legal authority to implement registration denial 
motorist enforcement. Virginia's I/M regulation requires that motorists 
obtain an emissions certificate demonstrating that they have passed a 
test or received a waiver in order to obtain a vehicle registration 
from the Department of Motor Vehicles (DMV). The Virginia SIP commits 
to maintain a compliance rate of 96%, which was used in the performance 
standard modeling demonstration.
    The motorist compliance enforcement program is to be implemented in 
part by the DMV, which is the lead agency for registration issuance. 
The Department of State Police and local police authorities are charged 
with enforcement against motorists who fail to comply with registration 
requirements.
    The Virginia SIP does not address mechanisms by which motorists 
will be notified of testing, readily visible means of determining 
compliance with the I/M program, penalties for motorists failing to 
comply with motor vehicle testing and registration, or mechanisms to 
prevent vehicle owners from avoiding testing by manipulating 
registrations. These, along with all other requirements of 40 CFR 
51.361 must be addressed in the SIP. Virginia has committed in the SIP 
to prepare a registration procedures manual to govern registration 
aspects of this portion of the program. It is expected that some of 
these requirements will be addressed in that procedures document.
    The requirements listed above are relatively minor in nature. These 
requirements must be satisfied prior to the end of the 18-month interim 
approval period. Virginia's SIP otherwise satisfies the requirements of 
40 CFR 51.361, and is approvable.
Motorist Compliance Enforcement Program Oversight--40 CFR 51.362
    The federal I/M rule requires that the enforcement program shall be 
audited regularly and shall follow effective program management 
practices, including adjustments to improve operation when necessary. 
The SIP must include quality control and quality assurance procedures 
to be used to insure the effective overall performance of the 
enforcement system. An information management system must be 
established which will characterize, evaluate and enforce the program.
    Virginia has not developed its procedures manual for its oversight 
program to ensure motorist compliance. Virginia must submit a 
procedures manual which satisfies the quality control and information 
management responsibilities of the motorist compliance enforcement 
oversight program section of the federal I/M rule, at 40 CFR 51.363.
    For a complete list of specific deficiencies with respect to 40 CFR 
51.362, refer to the technical support document (TSD) for this action, 
found in the EPA docket. These deficiencies are minor in nature, and 
must be addressed prior to the end of the 18-month interim approval 
period.
    Other than the deficiencies noted above, this portion of Virginia's 
SIP satisfies the requirements of 40 CFR 51.362, and is approvable.
Quality Assurance--40 CFR 51.363
    An ongoing quality assurance program shall be implemented to 
discover, correct and prevent fraud, waste, and abuse in the program. 
The program shall include covert and overt performance audits of the 
inspectors, audits of station and inspector records, equipment audits, 
and formal training of all state I/M enforcement officials and 
auditors. A description of the quality assurance program which includes 
written procedure manuals on the above discussed items must be 
submitted as part of the SIP.
    Virginia's SIP contains a detailed description of the elements of 
the quality assurance program and an appendix describing quality 
assurance and audit procedures. Virginia commits to conduct at least 
one covert audit per year per inspection bay, and at least two overt 
audits per year per inspection bay. However, the procedures manuals for 
use by Commonwealth quality assurance auditors have not yet been 
completed. These manuals must include detailed covert and overt audit 
procedures to be used by the Commonwealth for program oversight 
purposes. Virginia has committed to complete these audit manuals by 
December 1, 1996.
    This lack of detailed audit procedures manuals is a minor 
deficiency, and therefore the Commonwealth must complete and submit 
these manuals by the end of the 18-month interim approval period.
    The Virginia SIP otherwise meets the quality assurance requirements 
of section 40 CFR 51.363, and is approvable.
Enforcement Against Contractors, Stations and Inspectors--40 CFR 51.364
    Enforcement against licensed stations, contractors and inspectors 
shall include swift, sure, effective, and consistent penalties for 
violation of program requirements. The federal I/M rule requires the 
establishment of minimum penalties for violations of program rules and 
procedures which can be imposed against stations, contractors and 
inspectors. The legal authority for establishing and imposing 
penalties, civil fines, license suspensions and revocations must be 
included in the SIP. State quality assurance officials shall have the 
authority to temporarily suspend station and/or inspector licenses 
immediately upon finding a violation that directly affects emission 
reduction benefits, unless constitutionally prohibited. An official 
opinion explaining any state constitutional impediments to immediate 
suspension authority must be included in the submittal. The SIP shall 
describe the administrative and judicial procedures and 
responsibilities relevant to the enforcement process, including which 
agencies, courts and jurisdictions are involved, who will prosecute and 
adjudicate cases and the resources and sources of those resources which 
will support this function.
    Virginia's regulations establish a general enforcement process, 
including: issuance of notices of violation (NOVs), hearing processes, 
and avenues of appeal. Virginia has several avenues for adjudicating 
violation cases--including formal fact findings, formal DEQ hearings, 
and the ability to suspend stations or inspectors without a hearing, in 
certain instances. Virginia's regulation provides that penalties may be 
imposed against station owner permittees or against stations, as well 
as against inspectors.
    In the cases where testing privileges are suspended, inspectors 
must demonstrate their ability to properly perform test procedures 
before testing privileges may be restored. Suspended inspectors are 
barred from participating in inspection operations during the term of 
the suspension.
    Virginia's SIP includes provisions to maintain and submit to EPA 
records of all enforcement actions, including: warnings, violations, 
civil fines, suspensions, and license revocations, and violations. The 
DEQ will maintain this information in a ``Violation History Report'' 
for each station and each inspector.
    The Virginia SIP includes legal authority to establish and impose 
penalties against stations and inspectors participating in the enhanced 
I/M program. The Commonwealth has not yet adopted and submitted a 
penalty schedule for inspectors and test stations in the SIP, however 
the SIP contains a commitment to do so prior to program

[[Page 57352]]

start-up. The lack of a penalty schedule is a minor deficiency, and 
Virginia must adopt and submit an acceptable penalty schedule prior to 
the end of the 18-month interim approval period.
    With the exception of the lack of a penalty schedule, this 
submittal meets the enforcement requirements of this section of the I/M 
rule.
Data Collection--40 CFR 51.365
    Accurate data collection is essential to the management, evaluation 
and enforcement of an I/M program. The federal I/M regulation requires 
data to be gathered on each individual test conducted and on the 
results of the quality control checks of test equipment required under 
40 CFR 51.359.
    Virginia's I/M regulation does not indicate specific data elements 
to be entered by inspectors and reported to the Commonwealth. However, 
the regulation does require the inspector to accurately identify and 
enter vehicle and owner information for the specific test.
    The Commonwealth does commit to submit annual reports containing 
summaries of test data, quality assurance, and quality control 
information based upon program test data. A commitment to submit 
biennial reports to EPA which adequately address reporting requirements 
set forth in 40 CFR 51.366(e) is also included in the SIP.
    The submittal does not require that the specific data elements 
identified in 40 CFR 51.365(a) be collected and reported to the 
Commonwealth. This is a minor deficiency which must be corrected prior 
to the end of the 18-month interim approval period. This requirement 
can be satisfied by Virginia requiring these data elements to be 
collected. Two avenues for this requirement are via the regulation, or 
through the test equipment specifications (i.e. by requiring the test 
equipment to prompt the inspector to enter these elements and by 
blocking testing if the data is not entered).
    With the exception of a requirement for collection of the specific 
data elements, described above, the Virginia SIP meets the data 
analysis and reporting requirements of this section of the I/M rule.
Data Analysis and Reporting--40 CFR 51.366
    Data analysis and reporting are required to allow for monitoring 
and evaluation of the program by the state and EPA. The federal I/M 
rule requires annual reports to be submitted which provide information 
and statistics and summarize activities performed for each of the 
following programs: testing, quality assurance, quality control, and 
enforcement. These reports are to be submitted by July and shall 
provide statistics for the period of January to December of the 
previous year. A biennial report shall be submitted to EPA which 
addresses changes in program design, regulations, legal authority, 
program procedures and any weaknesses in the program found during the 
two year period and how these problems will be or were corrected.
    Virginia's SIP commits to submit annual statistical data summaries 
of activities related to testing, quality assurance, quality control, 
and enforcement programs, beginning January 1, 1998, containing data 
from the previous calendar year. Since Virginia's program is scheduled 
to begin in the month of July, not January, this reporting schedule is 
acceptable. Virginia's SIP contains an appendix (Appendix 12) which 
describing program statistics specific data elements in these annual 
reports. The data elements specified comply with the requirements of 40 
CFR 51.366.
    For a list of the specific data elements to be submitted in each of 
the annual reports, refer to the TSD for this rulemaking action.
Inspector Training and Licensing or Certification--40 CFR 51.367
    The federal I/M rule requires all inspectors to be formally trained 
and licensed or certified to perform inspections.
    Virginia's SIP contains regulatory authority requiring that program 
inspectors complete DEQ-approved formal training courses and then pass 
a qualification test, prior to becoming a licensed inspector. A 
description of the written and hands-on tests that inspectors are 
required to pass are described in Virginia's regulation and in Appendix 
13 of the SIP. The SIP also addresses requirements for obtaining an 
inspector's license and describes the licensing process. A list of 
elements to be covered by Virginia's inspector training program is 
included in Virginia's I/M rule, and is detailed in the TSD for this 
action.
    Virginia's regulation requires inspectors to be relicensed every 
three years, and requires inspectors to undergo the same training and 
hands-on testing required to initially obtain a license, in order to be 
relicensed. EPA rules require relicensing every two years, however, 
since Virginia's requirements are stricter than federal rules require, 
EPA considers the Commonwealth's three-year license period to be 
acceptable.
    The Virginia SIP satisfies the inspector training and licensing 
requirements of 40 CFR 51.367, and is approvable.
Public Information and Consumer Protection--40 CFR 51.368
     The federal I/M rule requires the SIP to include public 
information and consumer protection programs.
    Virginia's plan to develop public information and consumer 
protection plans is described in SIP, and elements to be included in 
those plans are listed in a ``Public Information Plan'' contained in 
Appendix 15 of the SIP. Virginia commits in the SIP to complete 
development of the actual plan by January 1, 1997.
    The Commonwealth intends to operate public referee stations, where 
testing disputes can be resolved. Additionally, the Commonwealth 
intends to operate consumer complaint hotline services to subject 
motorists. Additionally, Virginia describes strategies to educate the 
public on the I/M program in a public awareness plan contained in the 
SIP. Finally, Virginia intends to make statistical information 
available to the public regarding the repair performance effectiveness 
of repair facilities within the program area, per 40 CFR 51.369. For 
details regarding elements to be included in the ``Public Information 
Plan'', refer to the TSD for this action or to the SIP narrative 
document contained in the SIP.
    The Virginia SIP submittal meets the public information and 
consumer protection requirements of the I/M rule, however, Virginia 
must finalize and formally submit its ``Public Information Plan''. This 
is a minor deficiency, which must be corrected prior to the end of the 
18-month interim approval period. Other than the deficiency cited 
above, Virginia's SIP satisfies the requirements of 40 CFR 51.368, and 
is approvable.
Improving Repair Effectiveness--40 CFR 51.369
    Effective repairs are the key to achieving program goals. The 
federal
I/M rule requires states to take steps to ensure that the capability 
exists in the repair industry to repair vehicles. The SIP must include 
a description of the technical assistance program to be implemented, a 
description of the procedures and criteria to be used in meeting the 
performance monitoring requirements required in the federal regulation, 
and a description of the repair technician training resources available 
in the community.

[[Page 57353]]

    Virginia's SIP commits to track the effectiveness of repair 
facilities in the conducting emissions repairs under the enhanced I/M 
program. The SIP also contains a commitment to provide to the affected 
public the minimum performance monitoring information required by 40 
CFR 51.369. A completed repair form, will be required prior to 
motorist's receipt of a retest. However, the SIP does not contain a 
detailed plan for performance monitoring, per 40 CFR 51.369(b).
    Virginia has established in its SIP that insufficient emissions 
repair training exists and commits to work with vocational schools to 
provide for availability of better training. Virginia also commits in 
its SIP to establish or operate a repair technician hotline to assist 
repair technicians and to provide technical repair information for 
emissions-related repairs. A description of repair training available 
in the community must be submitted.
    The Virginia SIP meets the requirements for improving repair 
effectiveness, with the exception of a repair performance monitoring 
program, per 40 CFR 51.369(b) and a description of available training, 
per 40 CFR 51.369(c). However, this is a minor deficiency and must be 
corrected prior to the end of the 18-month interim approval period in 
order for EPA to fully approve the I/M SIP revision.
    Other than the minor deficiencies cited above, this requirement 
satisfies the requirements of 40 CFR 51.369, and is approvable.
Compliance With Recall Notices--40 CFR 51.370
    The federal I/M rule requires states to establish methods to ensure 
that vehicles that are subject to enhanced
I/M and are included in an emission related recall receive any recall 
related repairs prior to receiving an emission test and renewing 
vehicle registration.
    Virginia's I/M regulation requires that motor vehicles show proof 
of compliance with emissions-related recalls prior to receiving an 
emissions inspection under the enhanced I/M program. Per EPA's I/M 
rule, Virginia must maintain a database of outstanding emissions-
related recalls for vehicles registered in the I/M program area. 
Motorists having vehicles which are subject to an outstanding recall 
must show proof of compliance with the recall in order to obtain an 
emissions test.
    Virginia has not yet completed its recalls compliance procedures, 
since EPA has not completed its guidance on emissions recall 
compliance. The Commonwealth has committed in its SIP to complete its 
recall procedures within six months of EPA's completion of recall 
guidance. These procedures must address a process for notifying 
motorists of outstanding recalls, a means of identifying vehicles 
having an unresolved recall at I/M testing stations, quality control 
methods to ensure recall compliance, and a database system to identify 
and track vehicles subject to outstanding recalls. Additionally, 
Virginia must prepare and submit annual reports with statistical 
information regarding compliance with emissions recalls in the enhanced 
I/M program area.
    Virginia lacks only detailed recall compliance procedures and a 
commitment to annually report recall compliance information to EPA, 
therefore, this is a minor deficiency. However, Virginia must correct 
this deficiency prior to the end of the 18-month interim approval 
period. Otherwise, Virginia's SIP satisfies the requirements of 40 CFR 
51.370.
On-Road Testing--40 CFR 51.371
    On-road testing is required in enhanced I/M areas. The use of 
either remote sensing devices (RSD) or roadside pullovers including 
tailpipe emission testing can be used to meet the federal regulations. 
The program must include on-road testing of 0.5% of the subject fleet 
or 20,000 vehicles, whichever is less, in the enhanced I/M program 
area. Motorists that have passed an emission test and are found to be 
high emitters as a result of an on-road test shall be required to pass 
an out-of-cycle test.
    Section 46.2-1178.1 of the Virginia Motor Vehicle Emissions Control 
Law provides Virginia legal authority to conduct on-road testing and to 
assess civil penalties against motorists whose vehicles emit over 
regulatory standards set by the Commonwealth for on-road testing, 
unless the vehicle passes or is waived under an out-of-cycle emissions 
test.
    Virginia's I/M regulation sets forth a description of the on-road 
testing program and the emissions standards cars must meet to pass this 
testing. On-road testing in Virginia's program will be conducted via 
either remote sensing equipment, or by roadside pullover and a two-
speed idle test. Vehicles must comply with standards set by Virginia 
for relevant pollutants, including CO for remote sensing tests, and HC 
and CO for two-speed idle tests. Virginia will engage a contractor, as 
needed, to conduct roadside testing to satisfy the requirements of 40 
CFR 51.371.
    Under Virginia's proposed program, vehicles which fail on-road 
testing standards may be retested (outside of the normal biennial 
cycle) and repaired, or waived, to avoid civil penalties. Motorists' 
vehicles that receive a waiver from regularly scheduled I/M testing are 
exempt from civil penalties related to on-road testing. Motorists 
having vehicles that fail an on-road test, who either do not obtain a 
follow-up test, or whose vehicles fail the test and are not repaired to 
pass an emissions test are subject to the penalties set forth in 
Virginia's regulation.
    The Commonwealth's SIP submittal does not, however, contain 
sufficient information regarding on-road testing resource allocations, 
including information on staffing requirements for both the 
Commonwealth and the private testing vendor. Additionally, the SIP 
lacks methods for analyzing and reporting the results of on-road 
testing. These are, however, minor deficiencies and must be corrected 
in the final I/M SIP revision submitted by the end of the 18-month 
interim period, either by submitting an on-road testing procedures 
manual or the request for proposals (RFP) for the contractor hired to 
operate the on-road testing program.
    Otherwise, this submittal satisfies the requirements of 40 CFR 
51.371, and is approvable.
State Implementation Plan Submissions/Implementation Deadlines--40 CFR 
51.372-51.373
    The federal I/M rule requires states to provide in their I/M SIP a 
schedule for implementation of the enhanced I/M program described in 
the SIP, including interim milestone dates leading to mandatory 
testing. A list of milestones which must be included, at a minimum, is 
contained in 40 CFR 51.372. Additionally, 40 CFR 51.373 sets deadlines 
by which I/M programs must be adopted and put in place. However, 
language in the recently enacted National Highway Systems Designation 
Act, granted states additional time to adopt and submit I/M SIPs to 
satisfy the requirements of the Clean Air Act. States were to submit 
SIPs, including proposed regulations if necessary, to EPA by March 27, 
1996, and were granted eighteen months from the date of EPA interim 
approval to establish the effectiveness of the program. The NHSDA 
deadlines supersede any program implementation deadlines contained in 
40 CFR 51.373.
    Virginia's SIP contains a list of milestones and associated dates. 
Under this schedule, testing to include all aspects of the new enhanced 
I/M program, using phase-in test standards and a phased in waiver 
limit, is to commence on July 1, 1997. Final test

[[Page 57354]]

procedures and test equipment specifications are to be adopted by 
October 1, 1996. All official testing inspectors and stations are to be 
licensed by June 1, 1997. Virginia's waiver cost limit will be fully 
phased in over one biennial test cycle, to be at the full federal limit 
by July 1, 1998. Final testing standards, or cutpoints, will replace 
the phase-in standards at the beginning of the second biennial test 
cycle, July 1, 1999.
    Virginia has not listed dates by which all outstanding procedures 
documents are to be finalized and submitted to EPA. Virginia has made 
commitments to complete many of these procedures throughout the SIP. 
Milestones and dates for completion of any outstanding procedures 
documents should be listed in this portion of the SIP. This is however, 
a minor deficiency, which the Commonwealth must complete prior to the 
end of the 18-month interim approval period.
    Otherwise, Virginia's SIP satisfies the requirements of 40 CFR 
51.372 and 51.373, and is therefore approvable.

III. Discussion for Rulemaking Action

    Today's notice of proposed rulemaking begins a 30 day clock for the 
state to make a commitment to EPA to correct the major elements of the 
SIP that EPA considers deficient. These elements include the: enhanced 
I/M performance standard modeling demonstration, program evaluation 
methodology, I/M test procedures, and I/M test equipment 
specifications. If the Commonwealth does not make such commitments 
within 30 days, EPA today is proposing in the alternative that this SIP 
revision be disapproved.
    Within 30 days, the Commonwealth must make a commitment to EPA to 
correct these deficiencies by a date certain within 1 year of the 
interim approval date, or in certain cases a date certain prior to the 
commencement of testing.
    If the Commonwealth makes the commitment within 30 days, EPA's 
conditional approval of the plan will last until the date by which the 
state has committed to cure all of the deficiencies. EPA expects that 
within this period Virginia will not only correct the deficiencies as 
committed to by the Commonwealth, but that Virginia will also begin 
program start-up within 12 months of the final interim rulemaking. If 
the state does not correct deficiencies and implement the interim 
program by November 15, 1997, EPA is proposing in this notice that the 
interim approval will convert to a disapproval after a finding letter 
is sent to the state.

IV. Explanation of the Interim Approval

    At the end of the 18-month interim period, the approval status for 
this program will automatically lapse pursuant to the NHSDA. It is 
expected that the Commonwealth will at that time be able to make a 
demonstration of the program's effectiveness using an appropriate 
evaluation criteria. As EPA expects that these programs will have 
started on or before November 15, 1997, the Commonwealth will have at 
least six months of program data that can be used for the 
demonstration. If the Commonwealth fails to provide a demonstration of 
the program's effectiveness to EPA within eighteen months of the final 
interim rulemaking, the interim approval will lapse, and EPA will be 
forced to disapprove the state's permanent I/M SIP revision. If the 
Commonwealth's program evaluation demonstrates a lesser amount of 
emission reductions actually realized than were claimed in the state's 
previous submittal, EPA will adjust the Commonwealth's credits 
accordingly, and use this information to act on the state's permanent 
I/M program.

V. Further Requirements for Permanent I/M SIP Approval

    At the end of the 18-month period, final approval of the 
Commonwealth's plan will be granted based upon the following criteria:
    1. Virginia has complied with all the conditions of its commitment 
to EPA,
    2. EPA's review of the Commonwealth's program evaluation confirms 
that the appropriate amount of program credit was claimed by the state 
and achieved with the interim program,
    3. Final program regulations are submitted to EPA, and
    4. The Virginia I/M program meets all of the requirements of EPA's 
I/M rule, including those deficiencies found minor, or de minimis, for 
purposes of interim approval.

VI. EPA's Evaluation of the Interim Submittal

    EPA's review of the Commonwealth's SIP indicates that with 
satisfaction of the conditions described above, the Commonwealth will 
have adopted an enhanced I/M program in accordance with the 
requirements of the NHSDA. EPA is proposing conditional, interim 
approval of the Virginia SIP revision for an enhanced I/M program, 
which was submitted on March 27, 1996. EPA is soliciting public 
comments on the issues discussed in this notice or on other relevant 
matters. These comments will be considered before taking final interim 
action. Interested parties may participate in the federal rulemaking 
procedure by submitting written comments to the EPA Regional office 
listed in the Addresses section of this document.

Proposed Action

    EPA is proposing conditional interim approval of this revision to 
the Virginia SIP for an enhanced I/M program if a commitment is 
received from the Commonwealth within 30 days of the date of this 
proposal, to correct the identified deficiencies by a date certain 
within one year from the date of the final interim approval action.
    The conditions for approvability are as follows:
    (1) Virginia must formally submit, by a date certain within one 
year from interim conditional approval, new modeling to demonstrate 
that the program will meet the enhanced I/M performance standard by the 
first program evaluation date, for all localities which are part of the 
enhanced I/M program. The Commonwealth's revised modeling must 
correspond to the actual I/M program configuration, including actual 
test methods and start dates for all I/M program tests, actual 
cutpoints to be in-place for the evaluation year, and all other program 
assumptions as they exist in the SIP.
    (2) The Commonwealth must submit to EPA as a SIP amendment by a 
date certain within twelve months of the final interim ruling, the 
final Virginia I/M regulation which requires that mass-based emission, 
transient cycle testing be performed on 0.1% of the subject fleet each 
year, per 40 CFR 51.353(c)(3). This program evaluation scheme must 
satisfy the program evaluation elements specified in 40 CFR 51.353(c), 
including a program evaluation schedule, a protocol for the testing, 
and a system for collection and analysis of program evaluation data;
    (3) The Commonwealth must submit to EPA a commitment (along with a 
draft procedures document or revised draft regulation containing these 
procedures) to adopt approvable test procedures for its two-mode ASM 
test, within 30 days. Then by a date certain within one year and prior 
to the start of enhanced testing, the Commonwealth must submit the 
final Virginia I/M regulation or test procedures document which 
satisfies this requirement. If any alternative evaporative system test 
procedures are to be utilized, testing procedures for those tests must 
also be formally submitted at that time;
    (4) The Commonwealth must submit to EPA, within 30 days, a 
commitment

[[Page 57355]]

(along with a draft test equipment specifications or revised draft 
regulation containing draft test equipment specifications) to adopt 
final test equipment specifications. Then by a date certain within one 
year and prior to the start of enhanced testing, the Commonwealth must 
submit the final test equipment specifications for all test equipment 
to be used in the program. This includes specifications for equipment 
to perform the following tests: ASM2, two-speed idle, evaporative 
system pressure testing, and evaporative system purge testing. These 
specifications must be EPA-approved and satisfy the requirements of 40 
CFR 51.358.
    If the Commonwealth fails to satisfy the above conditions by a date 
certain within one year, EPA proposes that the conditional interim 
approval will convert to a disapproval upon a letter from EPA 
indicating that the Commonwealth has failed to meet its conditions for 
interim approval.
    The following minor deficiencies must be corrected in the final I/M 
SIP revision submitted by the end of the 18 month interim period:
    (1) The SIP lacks a detailed description of the elements to satisfy 
the test frequency requirements required under 40 CFR 51.355(a), 
particularly regarding scheduling of vehicles for testing and the 
selection scheme for the biennial program inspections, as well as a 
description of how test frequency will be integrated with the 
registration denial motorist enforcement process;
    (2) The SIP does not fully account for all exceptions from testing

    Nothing in this action should be construed as permitting or 
allowing or establishing a precedent for any future request for 
revision to any state implementation plan. Each request for revision to 
the state implementation plan shall be considered separately in light 
of specific technical, economic, and environmental factors and in 
relation to relevant statutory and regulatory requirements.
    Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., EPA 
must prepare a regulatory flexibility analysis assessing the impact of 
any proposed or final rule on small entities. 5 U.S.C. 603 and 604. 
Alternatively, EPA may certify that the rule will not have a 
significant impact on a substantial number of small entities. Small 
entities include small businesses, small not-for-profit enterprises, 
and government entities with jurisdiction over populations of less than 
50,000.
    SIP approvals under section 110 and subchapter I, part D of the 
Clean Air Act do not create any new requirements but simply approve 
requirements that the state is already imposing. Therefore, because the 
federal SIP approval does not impose any new requirements, the 
Administrator certifies that it does not have a significant impact on 
any small entities affected. Moreover, due to the nature of the 
federal-state relationship under the CAA, preparation of a flexibility 
analysis would constitute federal inquiry into the economic 
reasonableness of state action. The Clean Air Act forbids EPA to base 
its actions concerning SIPs on such grounds. Union Electric Co. v. U.S. 
EPA, 427 U.S. 246, 255-66 (1976); 42 U.S.C. 7410(a)(2).
    Under section 202 of the Unfunded Mandates Reform Act of 1995 
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA 
must prepare a budgetary impact statement to accompany any proposed or 
final rule that includes a federal mandate that may result in estimated 
costs to state, local, or tribal governments in the aggregate, or to 
the private sector, of $100 million or more. Under section 205, EPA 
must select the most cost-effective and least burdensome alternative 
that achieves the objectives of the rule and is consistent with 
statutory requirements. Section 203 requires EPA to establish a plan 
for informing and advising any small governments that may be 
significantly or uniquely impacted by the rule.
    EPA has determined that the approval action proposed/promulgated 
does not include a federal mandate that may result in estimated costs 
of $100 million or more to either state, local, or tribal governments 
in the aggregate, or to the private sector. This federal action 
approves pre-existing requirements under state or local law, and 
imposes no new federal requirements. Accordingly, no additional costs 
to state, local, or tribal governments, or to the private sector, 
result from this action.
    This action has been classified as a Table 3 action for signature 
by the Regional Administrator under the procedures published in the 
Federal Register on January 19, 1989 (54 FR 2214-2225), as revised by a 
July 10, 1995 memorandum from Mary Nichols, Assistant Administrator for 
Air and Radiation. The Office of Management and Budget (OMB) has 
exempted this regulatory action from E.O. 12866 review.
    The Administrator's decision to approve or disapprove the Virginia

enhanced I/M SIP revision will be based on whether it meets the 
requirements of section 110(a) (2)(A)-(K) and part D of the Clean Air 
Act, as amended, and EPA regulations in 40 CFR part 51.
