Summary:
On March 6, 2015 (80 FR 12264), the U.S. Environmental
Protection Agency (EPA) established a final rule for implementing the 2008
ozone national ambient air quality standards (NAAQS). This rule addresses a
range of nonattainment area state implementation plan (SIP) requirements for the
2008 ozone NAAQS, including how to address the revoked 1997 ozone NAAQS. The
board's ambient air quality regulation must be amended accordingly, as well as
the list of nonattainment areas, to reflect this change. Clarifying text has
also been added to the Regulation for Transportation Conformity and the
Regulation for General Conformity.

Part II
General Provisions
9VAC5-151-20. Applicability.
A. The provisions of this chapter shall apply to the
following actions:
1. Except as provided for in subsection C of this section or
40 CFR 93.126, conformity determinations are required for:
a. The adoption, acceptance, approval or support of
transportation plans and transportation plan amendments developed pursuant to
23 CFR Part 450 or 49 CFR Part 613 by a MPO or USDOT;
b. The adoption, acceptance, approval or support of TIPs and
TIP amendments developed pursuant to 23 CFR Part 450 or 49 CFR Part 613 by a
MPO or USDOT; and
c. The approval, funding, or implementation of FHWA/FTA
projects.
2. Conformity determinations are not required under this
chapter for individual projects that are not FHWA/FTA projects. However, 40 CFR
93.121 applies to the projects if they are regionally significant.
3. This chapter shall apply to conformity determinations for
which the final decision is made on or after the program approval date. For
purposes of applying this subdivision, the program approval date of the
regulation adopted by the board on March 26, 2007, shall be the date 30 days
after the date on which a notice is published in the Virginia Register
acknowledging that the administrator has approved the regulation adopted by the
board on March 26, 2007.
B. The provisions of this chapter shall apply in all
nonattainment and maintenance areas for transportation-related criteria
pollutants for which the area is designated nonattainment or has a maintenance
plan. The provisions of this chapter shall not apply in nonattainment and
maintenance areas that were designated nonattainment or maintenance under a
federal standard that has been revoked (see 9VAC5-20-204 B).
1. The provisions of this chapter apply with respect to
emissions of the following criteria pollutants: ozone, carbon monoxide (CO),
nitrogen dioxide (NO2), particles with an aerodynamic diameter less
than or equal to a nominal 10 micrometers (PM10); and particles with
an aerodynamic diameter less than or equal to a nominal 2.5 micrometers (PM2.5).
2. The provisions of this chapter also apply with respect to
emissions of the following precursor pollutants:
a. Volatile organic compounds (VOCs) and nitrogen oxides (NOX)
in ozone areas;
b. NOX in nitrogen dioxide areas;
c. VOCs or NOX or both, in PM10 areas:
(1) If the EPA Regional Administrator or the DEQ Director has
made a finding that transportation-related emissions of one or both of these
precursors within the nonattainment area are a significant contributor to the
PM10 nonattainment problem and has so notified the MPO and USDOT; or
(2) If the applicable implementation plan (or implementation
plan submission) establishes an approved (or adequate) budget for such
emissions as part of the reasonable further progress, attainment or maintenance
strategy;
d. NOX in PM2.5 areas:
(1) Unless both the EPA Regional Administrator and the DEQ
Director have made a finding that transportation-related emissions of NOX
within the nonattainment area are not a significant contributor to the PM2.5
nonattainment problem and have so notified the MPO and USDOT, or
(2) The applicable implementation plan (or implementation plan
submission) does not establish an approved (or adequate) budget for such
emissions as part of the reasonable further progress, attainment or maintenance
strategy; and
e. VOC, sulfur dioxide (S02) and/or ammonia (NH3)
in PM2.5 areas either:
(1) If the EPA Regional Administrator or the DEQ Director has
made a finding that transportation-related emissions of any of these precursors
within the nonattainment area are a significant contributor to the PM2.5
nonattainment problem and has so notified the MPO and USDOT, or
(2) If the applicable implementation plan (or implementation
plan submission) establishes an approved (or adequate) budget for such
emissions as part of the reasonable further progress, attainment or maintenance
strategy.
3. The provisions of this chapter apply to PM2.5
nonattainment and maintenance areas with respect to PM2.5 from re-entrained
road dust if the EPA Regional Administrator or the DEQ Director has made a
finding that re-entrained road dust emissions within the area are a significant
contributor to the PM2.5 nonattainment problem and has so notified
the MPO and USDOT, or if the applicable implementation plan (or implementation
plan submission) includes re-entrained road dust in the approved (or adequate)
budget as part of the reasonable further progress, attainment or maintenance
strategy. Re-entrained road dust emissions are produced by travel on paved and
unpaved roads (including emissions from anti-skid and deicing materials).
4. The provisions of this chapter apply to maintenance areas
through the last year of the area's maintenance plan approved under § 175A(b)
of the federal Clean Air Act, unless the applicable implementation plan
specifies that the provisions of this chapter shall apply for more than 20
years.
C. In order to receive any FHWA/FTA approved or funding
actions, including NEPA approvals, for a project phase subject to this chapter,
a currently conforming transportation plan and TIP must be in place at the time
of project approval as described in 40 CFR 93.114, except as provided by 40 CFR
93.114(b).
D. For areas or portions of areas that have been continuously
designated attainment or not designated for any National Ambient Air Quality
Standard for ozone, CO, PM10, PM2.5 or NO2
since 1990 and are subsequently redesignated to nonattainment or designated
nonattainment for any National Ambient Air Quality Standard for any of these
pollutants, the provisions of this chapter shall not apply with respect to that
National Ambient Air Quality Standard for 12 months following the effective
date of final designation to nonattainment for each National Ambient Air Quality
Standard for such pollutant.
Part II
General Provisions

system or any federal reserve bank to effect monetary or exchange rate policy.
r. Actions that implement a foreign affairs function of the
United States.
s. Actions or portions thereof associated with transfers of
land, facilities, title, and real properties through an enforceable contract or
lease agreement where the delivery of the deed is required to occur promptly
after a specific, reasonable condition is met, such as promptly after the land
is certified as meeting the requirements of the Comprehensive Environmental
Response, Compensation, and Liability Act (CERCLA), 42 USC 9601 et seq., and
where the federal agency does not retain continuing authority to control
emissions associated with the lands, facilities, title, or real properties.
t. Transfers of real property, including land, facilities, and

policy and to exercise the borrowing authority of the United States.
v. Air traffic control activities and adopting approach,
departure, and en route procedures for aircraft operations above the mixing
height specified in the applicable implementation plan. Where the applicable
implementation plan does not specify a mixing height, the federal agency may
use the 3,000 feet above ground level as a default mixing height, unless the
agency demonstrates that use of a different mixing height is appropriate
because the change in emissions at and above that height caused by the federal
action is de minimis.
3. Actions where the emissions are not reasonably foreseeable,
such as the following:
a. Initial outer continental shelf lease sales which are made
on a broad scale and are followed by exploration and development plans on a

with a conforming land management plan, that has been found to conform to the
applicable implementation plan. The land management plan shall have been found to
conform within the past five years.
G. Notwithstanding the other requirements of this section, a
conformity determination is not required for the following federal actions or
portions thereof:
1. The portion of an action that includes major or minor new or
modified stationary sources that require a permit under the new source review
program.
2. Actions in response to emergencies that are typically
commenced on the order of hours or days after the emergency and, if applicable,
that meet the requirements of subsection H of this section.
3. Research, investigations, studies, demonstrations, or
training (other than those exempted under subdivision F 2 of this section),
where no environmental detriment is incurred, or the particular action furthers
air quality research, as determined by the department.
4. Alteration and additions of existing structures as
specifically required by new or existing applicable environmental legislation
or environmental regulations (for example, hush houses for aircraft engines and
scrubbers for air emissions).
5. Direct emissions from remedial and removal actions carried
out under CERCLA and associated regulations to the extent the emissions either
comply with the substantive requirements of the new source review program,
or are exempted from other environmental regulation under the provisions of
CERCLA and applicable regulations issued under CERCLA.
H. Federal actions which are part of a continuing response to
an emergency or disaster under subdivision G 2 of this section and which are to
be taken more than six months after the commencement of the response to the
emergency or disaster under subdivision G 2 of this section are exempt from the
requirements of this subsection only if:
1. The federal agency taking the actions makes a written
determination that, for a specified period not to exceed an additional six
months, it is impractical to prepare the conformity analyses which would
otherwise be required and the actions cannot be delayed due to overriding
concerns for public health and welfare, national security interests, and
foreign policy commitments; or
2. For actions which are to be taken after those actions
covered by subdivision H 1 of this section, the federal agency makes a new
determination as provided in subdivision H 1 of this section, and:
a. Provides a draft copy of the written determinations
required to affected EPA regional offices, the affected states and air
pollution control agencies, and any federally recognized Indian tribal
government in the nonattainment or maintenance area. Those organizations shall
be allowed 15 days from the beginning of the extension period to comment on the
draft determination; and
b. Within 30 days after making the determination, publish a
notice of the determination by placing a prominent advertisement in a daily
newspaper of general circulation in the area affected by the action.
3. If additional actions are necessary in response to an
emergency or disaster under subdivision G 2 of this section beyond the
specified time period in subdivision 2 of this subsection, a federal agency may
make a new written determination as described in subdivision 2 of this
subsection for as many six-month periods as needed, but in no case shall this
exemption extend beyond three six-month periods except where an agency provides
information to EPA and the department stating that the conditions that gave
rise to the emergency exemption continue to exist and how such conditions
effectively prevent the agency from conducting a conformity evaluation.
I. Notwithstanding other requirements of this chapter,
actions specified by individual federal agencies that have met the criteria set
forth in subdivision J 1, J 2, or J 3 of this section and the procedures set
forth in subsection K of this section are presumed to conform, except as
provided in subsection M of this section. Actions specified by individual
federal agencies as presumed to conform shall not be used in combination with
one another when the total direct and indirect emissions from the combination
of actions would equal or exceed any of the rates specified in subdivisions
subdivision E 1 or E 2 of this section.
J. The federal agency shall meet the criteria for
establishing activities that are presumed to conform by fulfilling the
requirements set forth in either subdivision 1, 2, or 3 of this subsection.
1. The federal agency shall clearly demonstrate, using methods
consistent with this regulation, that the total of direct and indirect
emissions from the type of activities which would be presumed to conform would
not:
a. Cause or contribute to any new violation of any standard in
any area;
b. Interfere with the provisions in the applicable
implementation plan for maintenance of any standard;
c. Increase the frequency or severity of any existing
violation of any standard in any area;
d. Delay timely attainment of any standard or any required
interim emissions reductions or other milestones in any area including, where
applicable, emission levels specified in the applicable implementation plan for
purposes of:
(1) A demonstration of reasonable further progress;
(2) A demonstration of attainment; or
(3) A maintenance plan.
2. The federal agency shall provide documentation that the
total of direct and indirect emissions from the future actions would be below
the emission rates for a conformity determination that are established in
subsection B of this section, based, for example, on similar actions taken over
recent years.
3. The federal agency shall clearly demonstrate that the
emissions from the type or category of actions and the amount of emissions from
the action are included in the applicable implementation plan and the
department provides written concurrence that the emissions from the actions
along with all other expected emissions in the area will not exceed the
emission budget in the applicable implementation plan.
K. In addition to meeting the criteria for establishing
exemptions set forth in subdivision J 1, J 2, or J 3 of this section, the
following procedures shall also be complied with to presume that activities
shall conform:
1. The federal agency shall identify through publication in
the Federal Register its list of proposed activities that are presumed to
conform, and the basis for the presumptions. The notice shall clearly identify
the type and size of the action that would be presumed to conform and provide
criteria for determining if the type and size of action qualifies it for the
presumption;
2. The federal agency shall notify the appropriate EPA
regional office or offices, department, and local air quality agencies and,
where applicable, the lead planning organization, and the metropolitan planning
organization and provide at least 30 days for the public to comment on the list
of proposed activities presumed to conform. If the presumed to conform action
has regional or national application (e.g., the action will cause emission
increases in excess of the de minimis levels identified in subsection E of this
section in more than one EPA region), the federal agency, as an alternative to
sending it to EPA regional offices, may send the draft conformity determination
to EPA, Office of Air Quality Planning and Standards;
3. The federal agency shall document its response to all the
comments received and make the comments, response, and final list of activities
available to the public upon request; and
4. The federal agency shall publish the final list of such
activities in the Federal Register.
L. Emissions from the following actions are presumed to
conform:
1. Actions at installations with facility-wide emission
budgets meeting the requirements in 9VAC5-160-181 provided that the department
has included the emission budget in the EPA-approved applicable implementation
plan and the emissions from the action along with all other emissions from the
installation will not exceed the facility-wide emission budget.
2. Prescribed fires conducted in accordance with a smoke
management program that meets the requirements of EPA's Interim Air Quality
Policy on Wildland and Prescribed Fires (April 1998) or an equivalent replacement
EPA policy.
3. Emissions for actions that the department identifies in the
EPA-approved applicable implementation plan as presumed to conform.
M. Even though an action would otherwise be presumed to
conform under subsection I or L of this section, an action shall not be
presumed to conform and the requirements of 9VAC5-160-110 through
9VAC5-160-180, 9VAC5-160-182 through 9VAC5-160-184, and 9VAC5-160-190 shall
apply to the action if EPA or a third party shows that the action would:
1. Cause or contribute to any new violation of any standard in
any area;
2. Interfere with provisions in the applicable implementation
plan for maintenance of any standard;
3. Increase the frequency or severity of any existing
violation of any standard in any area; or
4. Delay timely attainment of any standard or any required
interim emissions reductions or other milestones in any area including, where
applicable, emission levels specified in the applicable implementation plan for
purposes of (i) a demonstration of reasonable further progress, (ii) a
demonstration of attainment, or (iii) a maintenance plan.
N. Any measures used to affect or determine applicability of
this chapter, as determined under this section, shall result in projects that
are in fact de minimis, shall result in the de minimis levels prior to the time
the applicability determination is made, and shall be state or federally
enforceable. Any measures that are intended to reduce air quality impacts for
this purpose shall be identified (including the identification and
quantification of all emission reductions claimed) and the process for
implementation (including any necessary funding of the measures and tracking of
the emission reductions) and enforcement of the measures shall be described,
including an implementation schedule containing explicit timelines for
implementation. Prior to a determination of applicability, the federal agency
making the determination shall obtain written commitments from the appropriate
persons or agencies to implement any measures which are identified as
conditions for making the determinations. The written commitment shall describe
the mitigation measures and the nature of the commitment, in a manner
consistent with the previous sentence. After this regulation is approved by EPA,
enforceability through the applicable implementation plan of any measures
necessary for a determination of applicability shall apply to all persons who
agree to reduce direct and indirect emissions associated with a federal action
for a conformity applicability determination.
