Approval and Promulgation of Implementation Plans; Carbon
Monoxide State Implementation Plan Revision State of New York and
Revision of Oxygenated Gasoline Control Period
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
SUMMARY: EPA is proposing the approval of portions of a request from
New York to revise its State Implementation Plan (SIP) related to the
control of carbon monoxide. EPA is proposing approval of New York's
vehicle miles travelled forecast, contingency measures, carbon monoxide
emission inventory, multi-state coordination letter, and Downtown
Brooklyn Master Plan. In addition, EPA is proposing approval of the
oxygenated gasoline program in the New York City consolidated
metropolitan statistical area during the four months when the area is
prone to high ambient concentrations of carbon monoxide. New York's
oxygenated fuels program also includes a provision for oxygenated fuels
to serve as a contingency measure in the Syracuse metropolitan
statistical area.
New York has recently updated its enhanced inspection and
maintenance submittal which EPA is currently reviewing. Therefore,
action on that program, along with the attainment demonstration, which
relies on the enhanced inspection and maintenance program, will be
taken in a separate Federal Register notice. These revisions have been
submitted in response to requirements established in the Clean Air Act
as amended in 1990 that the states develop a plan to attain the carbon
monoxide standard.

SUPPLEMENTARY INFORMATION:
Background
The Clean Air Act, as amended in 1990, sets forth a number of
requirements that states designated as moderate nonattainment for
carbon monoxide had to submit as revisions to their SIPs by November
15, 1992. Since the New York portion of the ``New York-Northern New
Jersey-Long Island'' carbon monoxide nonattainment area is classified
as a moderate 2 area (an area that has a design value of 12.8-16.4
ppm.), New York was required to make this submission. These
requirements are: an attainment demonstration, an enhanced vehicle
inspection and maintenance program, an oxygenated fuels rule, a vehicle
miles traveled forecast, contingency measures, a carbon monoxide
emission inventory, a revised new source review program, and multistate
coordination letter.
EPA has issued a ``General Preamble'' describing its preliminary
views on how it intends to review SIPs and SIP revisions submitted in
order to meet Title I requirements [see generally 57 FR 13498 (April
16, 1992) and 57 FR 18070 (April 28, 1992)]. The reader should refer to
the General Preamble for a more detailed discussion of the Title I
requirements and what EPA views as necessary to adequately comply with
Title I provisions.
On November 13, 1992, New York submitted to EPA proposed revisions
to its carbon monoxide SIP that addressed each of the above
requirements for its moderate carbon monoxide nonattainment area. In
addition, in a submittal dated March 21, 1994, New York submitted to
EPA additional information pertaining to its carbon monoxide SIP.
As part of Federal Environmental Impact Statement work, certain
projects in Brooklyn were identified as causing violations of the
carbon monoxide standard. The State said that they would revise the
carbon monoxide SIP to mitigate these problems. On September 21, 1990,
New York submitted a revision to the New York SIP to attain the carbon
monoxide air quality standard in the Brooklyn portion of the New York
City metropolitan area.
These three submittals are the subject of this Federal Register.
The following summarizes EPA's evaluation of New York's SIP submittals
and EPA's proposed actions. The details of EPA's review are contained
in the Technical Support Document available at EPA's Region II office.
[[Page 47912]]
Attainment Demonstration
Section 187(a)(7) of the Clean Air Act requires each state that
contains all or part of a moderate 2 area to submit to the
Administrator an attainment demonstration by November 15, 1992. This
attainment demonstration documents how the State will attain the 8-hour
carbon monoxide NAAQS of 9 ppm by December 31, 1995.
New York, using emissions from the EPA-approved MOBILE4.1 model,
demonstrated attainment of the carbon monoxide standard with the EPAapproved
CAL3QHC air quality dispersion model. New York took emission
reductions credit from enhanced I/M, oxygenated fuels, and the federal
motor vehicle control program (vehicle turnover) as control measures to
attain the standard. A detailed explanation of this modeling is
contained in the Technical Support Document.
New York's analysis demonstrated that all of the modeled
intersections attained the 8-hour carbon monoxide standard of 9 ppm.
The highest value obtained was 9.0 ppm which occurred at two
intersections. Since air quality values at the most congested
intersections was determined to not exceed the standard, New York has
demonstrated that the entire area will be in attainment for carbon
monoxide by December 31, 1995.
New York used appropriate modeling techniques and modeling inputs
in this demonstration, however one of the control measures used to
demonstrate attainment, the enhanced inspection and maintenance
program, submitted on November 15, 1993 had not been fully adopted in
accordance with State requirements. On July 31, 1995, New York
submitted an updated enhanced inspection and maintenance program which
EPA determined to be complete on August 2, 1995. EPA will take action
on the enhanced inspection and maintenance program and the attainment
demonstration in a separate Federal Register notice.
Enhanced Inspection and Maintenance Program
Section 187(a)(6) of the Clean Air Act requires implementation of
enhanced inspection and maintenance programs in moderate 2 carbon
monoxide nonattainment areas and includes provisions as required under
section 182(c)(3) concerning serious ozone nonattainment areas. Such
provisions require implementation of an enhanced inspection and
maintenance program in urbanized areas with a population greater than
200,000.
On November 15, 1993 New York submitted draft regulations and other
information pertaining to the enhanced inspection and maintenance
program. Since New York did not submit a fully adopted enhanced
inspection and maintenance program, on February 2, 1994 EPA notified
the State that this submittal was incomplete and a sanctions process
was begun. New York then made an updated submittal on July 31, 1995
which EPA will be taking action on in a separate Federal Register
notice.
Oxygenated Fuels Rule
I. Introduction
Section 211(m) of the Clean Air Act requires that various states
submit revisions to their SIPs, and implement oxygenated gasoline
programs by no later than November 1, 1992. This requirement applies to
all states with carbon monoxide nonattainment areas with design values
of 9.5 parts per million or more based generally on 1988 and 1989 data.
Each state's oxygenated gasoline program must require gasoline for the
specified control area(s) to contain not less than 2.7 percent oxygen
by weight during that portion of the year in which the areas are prone
to high ambient concentrations of carbon monoxide. Under section
211(m)(2), the oxygenated gasoline requirements are to generally cover
all gasoline sold or dispensed in the larger of the consolidated
metropolitan statistical area or the metropolitan statistical area in
which the nonattainment area is located. Under section 211(m)(2), the
length of the control period, to be established by the EPA
Administrator, shall not be less than four months in length unless a
state can demonstrate that, because of meteorological conditions, a
reduced control period will assure that there will be no carbon
monoxide exceedances outside of such reduced period. EPA announced
guidance on the establishment of control periods by area in the Federal
Register on October 20, 1992.\1\
\1\ See ``Guidelines for Oxygenated Gasoline Credit Programs and
Guidelines on Establishment of Control Periods under Section 211(m)
of the Clean Air Act as Amended--Notice of Availability,'' 57 FR
47849 (October 20, 1992).
State Submittal
In order to fulfill the Clean Air Act requirement, on September 27,
1993 New York submitted a request to revise its State Implementation
Plan to incorporate adopted revisions to Title 6 Subpart 225-3 of the
New York Code of Rules and Regulations, entitled ``Fuel Composition and
Use--Volatile Motor Fuel,'' effective on September 2, 1993.
Applicability and Program Scope
Section 211(m)(2) requires oxygenated gasoline to be sold during a
control period based on air quality monitoring data and established by
the EPA Administrator. New York has established control periods for the
New York City consolidated metropolitan statistical area and the
Syracuse metropolitan statistical areas which are consistent with the
1992 EPA guidance.
New York's oxygenated gasoline regulations require oxygenated
gasoline to be sold in the larger of the consolidated metropolitan
statistical area (CMSA) or metropolitan statistical area (MSA) in which
the nonattainment area is located, consistent with the requirements of
section 211(m)(2) of the Act. The New York City CMSA consists of the
following counties: Bronx, Kings, Queens, New York, Richmond, Orange,
Rockland, Putnam, Westchester, Nassau and Suffolk. New York's current
regulation requires oxygenated gasoline to be sold in this area from
October 1 through April 30. While this control period had been
appropriate in previous carbon monoxide control seasons in the New York
City CMSA, EPA is proposing to determine, based on more recent ambient
air monitoring data, that the appropriate oxygenated gasoline control
period for the area should be shorter in length. Four months is the
minimum program length allowed by the Clean Air Act, except as
indicated in section 211(m)(B) which, at the request of a state with
respect to any carbon monoxide nonattainment area, allows the EPA
Administrator to reduce the period below four months. Such a
determination can only occur if the State can demonstrate that due to
meteorological conditions a shorter period will assure that no carbon
monoxide exceedances will occur outside of that shorter period.
New York also requires the sale of oxygenated gasoline in any area
of the State which had been designated as nonattainment for carbon
monoxide but was redesignated as attainment, if it is required to
maintain the standard in that area.
In the case of the Syracuse metropolitan statistical area, which
has been officially redesignated as attainment for carbon monoxide (See
58 FR 50851), the oxygenated gasoline program is no longer required in
that area since the attainment demonstration did not depend on the
program. The oxygenated gasoline program constitutes the State's
contingency measure for the Syracuse metropolitan statistical area, in
[[Page 47913]]
the event that the carbon monoxide standard is violated in this area.
If this program should need to be re-instituted in this area, the
period of sale would be November 1 through the last day of February.
In this notice EPA is applying established Agency guidance
(announced for availability at 57 FR 47853, October 20, 1992) regarding
oxygenated gasoline control periods to determine the proper control
period length for the New York City CMSA. As part of the 1992 guidance
document, based on air quality data from 1990 and 1991, EPA suggested
that the proper control period for the New York City CMSA was October 1
through April 30. However, the 1992 guidance does not establish a
binding norm regarding control periods and provides that the
determination of the control period will be an issue to be finally
decided by EPA as part of the review of individual state SIP revisions
for oxygenated gasoline programs. For the reasons set forth below, EPA
is now proposing to determine that the appropriate control period is
from November 1 through the last day of February; EPA believes sale of
gasoline oxygenated to 2.7 percent by weight during the months of
October, March and April is no longer necessary for adequate carbon
monoxide control in the New York City CMSA.
Section 211(m), cited in the 1992 EPA guidance, requires control
period length to be decided by the EPA Administrator based on the
period an area is prone to high carbon monoxide concentrations. The
three-state New York City CMSA has not recorded an exceedance of the
carbon monoxide national ambient air quality standard (NAAQS) in the
three months proposed to be dropped since October of 1991. Furthermore,
since 1992 the CMSA has not been prone to high ambient concentrations
of carbon monoxide, during those three months. Under the approach used
in EPA's guidance, ``prone to high ambient concentrations of carbon
monoxide'' is a criterion more stringent than the NAAQS.
While the successful reduction in ambient carbon monoxide levels
during October, March and April in the New York City CMSA can in part
be attributed to the sale of oxygenated gasoline, EPA believes that
implementation of new programs under the Clean Air Act in the New York
City CMSA will adequately ensure continued observance of reduced levels
of carbon monoxide during the months of October, March and April.
Reformulated gasoline, a year round clean gasoline program, which was
implemented on January 1, 1995 in the New York City CMSA [see 59 FR
7716, February 16, 1994.] provides gasoline oxygenated to 2.0 percent.
EPA believes that implementation of enhanced inspection and maintenance
programs [40 CFR Part 51, Subpart S] and the turnover of the New York
City CMSA fleet, to newer, cleaner vehicles combined with the use of
reformulated gasoline will ensure continued lower carbon monoxide
emissions from motor vehicles for the CMSA during October, March and
April.
While the established guidance bases the determination of control
period only on air quality monitoring data (which exists for the entire
New York City CMSA for 1992 to 1995), EPA believes that it is prudent
also to provide a technical analysis further supporting the reduction
of oxygen content during the shoulder months in the area. To support
the contention that in future years, starting with 1996, without sales
of gasoline oxygenated to 2.7 percent, but with implementation of
federal reformulated gasoline (RFG) and enhanced I/M combined with
vehicle turnover carbon monoxide emissions will continue to be lower
during October, March and April in the area, EPA performed a series of
computer model runs. Since the first observance after the
implementation of the oxygenated fuels program of low CO levels during
those months was in 1993, average vehicle emissions from that year were
used as an upper limit in determining the adequacy of removal of the
higher oxygen content in October, March and April.
The comparison was performed utilizing the most current version of
EPA's emission factor model for mobile sources, MOBILE5a. All modeling
assumed implementation of RFG (with 2.0 percent oxygen content) for
1995 and later, and for 1996 and future years, the effect of an
enhanced I/M program are included. MOBILE5a variables such as vehicle
speeds and a vehicle miles traveled growth rate were supplied by the
New York State Department of Environmental Conservation. For further
details regarding the MOBILE5a runs and the subsequent comparisons, the
reader is referred to the technical support document. Modeling shows
that removing oxygenated gasoline (to 2.7 percent) but accounting for
the effects of RFG, enhanced I/M and vehicle turnover, vehicle
emissions of CO, through calendar year 2020 (based on an average day in
the CO season in each of those years), will still be at least 22.74
percent less than vehicle emissions of CO in 1993 with 2.7 percent
oxygenated gasoline. Thus elimination of oxygenated gasoline program
requirements in the shoulder months in the area appears to be
technically sound.
Based on the proposed determination that the appropriate control
period runs from November through February, EPA is proposing to approve
New York's oxygenated gasoline requirement only for that four month
period. This EPA action on New York's SIP revision takes into account
the interaction of the current New York regulation and the RFG
regulation promulgated by EPA on February 16, 1994. During the entire
seven month period of October through April, the current New York
standard for oxygen content in the New York portion of the New York
City CMSA is a minimum of 2.7 percent oxygen by weight. The same New
York portion of the New York City CMSA is also subject to RFG
requirements, which include a year-round oxygenate standard of 2.0
percent. 40 CFR section 80 subpart D. As discussed below, the RFG
requirements act to preempt an extension of the state oxygenated
gasoline provisions beyond the four month period prone to high ambient
concentrations of CO.
EPA's authority to regulate fuels and fuel additives is found in
section 211 of the Clean Air Act. Under section 211(c)(1), the
Administrator has the authority to control or prohibit the manufacture
and sale of fuels and fuel additives on the grounds of danger to public
health or impairment of emissions control devices. Section 211(c)(4)
provides that where the Administrator has set such a control or
prohibition under section 211(c)(1) applicable to a characteristic or
component of a fuel or fuel additive, no state may set a control or
prohibition respecting that characteristic or component, unless the
state control or prohibition is identical to the federal control or
prohibition. This provision preempts state fuel controls that are
nonidentical to federal section 211(c)(1) controls on the same
characteristic or component.
EPA promulgated the RFG program under the authority of sections
211(k) and 211(c)(1) [59 FR 7716, February 16, 1994]. RFG must contain
2.012xygen content by weight, and it is required year-round in the New
York City CMSA. In the absence of section 211(m), section 211(c)(4)
would preempt states from establishing their own minimum oxygen content
requirements different from the RFG requirements in RFG areas. Because
section 211(m) is a specific, more stringent requirement, it overrides
the general preemption provision, and states are not preempted from
complying with section 211(m) in RFG
[[Page 47914]]
areas. However, states are preempted from setting nonidentical controls
or prohibitions on oxygen content in RFG areas to the extent that such
controls or prohibitions are not mandated by section 211(m).
In this notice, EPA is proposing to determine that the New York
City CMSA is prone to high ambient concentrations of carbon monoxide
during the four month period of November through February. Section
211(m) only requires states to adopt 2.712xygenated gasoline
requirements for the period prone to high ambient concentrations of
carbon monoxide, as determined by the Administrator. Thus, upon
finalization of EPA's proposed determination, section 211(m) would only
require New York to adopt a 2.7minimum oxygen content standard for
four months. The RFG oxygen content requirement preempts any state from
prescribing or enforcing oxygen content requirements in this area that
go beyond what is mandated by section 211(m). Because New York would be
preempted from enforcing the additional months of October, March and
April, EPA is only proposing to approve New York's oxygenated fuel
requirements for the months of November through February in the
counties of Bronx, Kings, Queens, New York, Richmond, Orange, Rockland,
Putnam, Westchester, Nassau and Suffolk. EPA is publishing concurrently
with this notice a Notice of Proposed Rulemaking to approve
Connecticut's oxygenated gasoline SIP submission. That notice proposes
to establish the same four-month control period for the Connecticut
portion of the New York-New Jersey-Connecticut CO nonattainment area.
New York's four-month control period will be consistent with
Connecticut's four-month control period.
Through a letter dated August 11, 1995 from New York State
Department of Environmental Conservation Deputy Commissioner David
Sterman to EPA Regional Administrator Jeanne Fox, the State of New York
has communicated to EPA their intent to revise Subpart 225-3 to reflect
the shorter control period, identical to the control period EPA is
proposing to approve. In the same letter, New York requests EPA to
revise its control period guidance to shorten the period to four
months. Rather than revising the guidance, in this proposal EPA is
applying the guidance to make a determination that the appropriate
control period for this area is four months. EPA believes it is
appropriate to approve New York's oxygenated fuel requirement for only
four of the seven months provided in New York's submission because this
approval would not increase the stringency of the State submission and
conforms with the State's intended revisions to the regulation. Also,
section 110(a)(2)(A) requires SIPs to include ``enforceable * * *
control measures.'' EPA only has authority to approve the enforceable
portion of the State submission, which, upon finalization of EPA's
proposed determination, would correspond to a four month control
period.
Transfer Documents
New York has included requirements related to transfer
documentation in its regulation. These transfer document requirements
enhance the enforcement of the oxygenated gasoline regulation, by
providing a traceable record for each gasoline sample taken by state
enforcement personnel.
Enforcement and Penalty Schedules
State oxygenated gasoline regulations must be enforceable by the
state oversight agency. EPA recommends that states visit regulated
parties during a given control period. Inspections should consist of
product sampling and record review. In addition, each state should
devise a comprehensive penalty schedule. Penalties should reflect the
severity of a party's violation, the compliance history of the party,
as well as the potential environmental harm associated with the
violation. New York has provided for a comprehensive penalty schedule
in accordance with EPA guidance. In addition to having authority to
assess a civil administrative penalty, the State has authority to use
further measures such as issuance of abatement orders.
Waiver Provisions
EPA is proposing to not approve sections 225-3.8 and 225-3.9(a),
which would allow the Commissioner of the Department of Environmental
Conservation, upon application, to grant waivers from the State's
minimum oxygen content requirement, and the minimum Reid vapor pressure
(RVP) requirement, respectively, due to a shortage of gasoline which
meets those requirements.
In its revision to section 225-3.8, the State revised the RVP
waiver provision originally approved by EPA at 54 FR 26030 on June 21,
1989. At the time, New York had adopted its own summertime RVP
standards, more stringent than national standards, as part of an
initiative on the parts of northeastern states to make progress toward
achieving the National Ambient Air Quality Standard for ozone. Since
that time, the national RVP standards have been lowered to the same
levels as were initiated by New York in 1989. Because the State's RVP
standards are again equal to EPA's national standards and because
gasoline RVP is regulated on the Federal level, New York can no longer
effectively grant waivers for RVP. To avoid confusion that EPA's
approval of the New York RVP requirement might mean that State waivers
would waive the Federal requirements, EPA is not approving the State's
waiver provision (section 225-3.8).
EPA is also proposing to not approve section 225-3.9(a), which
allows the State to grant waivers of the minimum oxygen content
requirement. Generally, EPA does not approve state variance or waiver
provisions in SIP submissions that would allow the state to grant
waivers without EPA approval. To the extent that a waiver provision
would allow a state to exempt a source from compliance required by the
statute, such a waiver could be inconsistent with the applicable
statutory requirements. However, in guidance for oxygenated fuels
programs, EPA has identified circumstances under which the Agency may
approve a very narrow state variance provision authorizing the state to
allow supply of nonconforming gasoline due to extraordinary
circumstances. See Guidelines for Oxygenated Gasoline Credit Programs
under section 211(m) of the Clean Air Act as Amended. The guidance
establishes five conditions to be included in an approvable variance
provision. One of these conditions is that the ``refiner agrees to make
up the air quality detriment associated with the nonconforming
gasoline, where practicable.'' The New York variance provision does not
include this requirement. This is a key condition because it reduces
the likelihood that granting of a variance would detrimentally affect
the environment. Given this deviation from the conditions specified in
the guidance, EPA believes that the New York variance provision is not
approvable because the limits of the discretion do not clearly meet EPA
policy for approving such an exercise of discretion, EPA is not
approving this waiver provision. Such waivers would need to be approved
by EPA as SIP revisions consistent with EPA policy on such waivers.
Test Methods and Laboratory Review
EPA's sampling procedures are detailed in Appendix D of 40 CFR Part
80. EPA has recommended, in its credit program guidelines, that states
adopt these sampling procedures. New York has incorporated by reference
EPA sampling methods.
[[Page 47915]]
Labeling
EPA requires the labeling of gasoline pumps and has strongly
recommended that states adopt their own labeling regulations,
consistent with the federal regulation. New York has adopted labeling
regulations consistent with the federal regulation.
Credit Program
EPA guidance announced the availability of an optional oxygenated
gasoline credit program (57 FR 47849, October 20, 1992), where
marketable oxygen credits may be generated from the sale of gasoline
with a higher oxygen content than is required. New York has opted not
to implement such a credit program and requires a per-gallon minimum
oxygen content of 2.7 10uring the control period.
II. Proposed Action
EPA's review of Subpart 225-3 indicates that the State has adopted
an oxygenated gasoline regulation in accordance with the requirements
of the Clean Air Act. Therefore, EPA is proposing to approve New York's
Subpart 225-3 oxygenated gasoline program as a revision to the State's
SIP. EPA is proposing not to approve sections 225-3.8 and 225-3.9(a),
which unduly allow the State's Commissioner to grant waivers from the
minimum oxygen content and minimum RVP requirement, respectively.
Vehicle Miles Travelled Forecast
Section 187(a)(2)(A) of the Clean Air Act requires moderate carbon
monoxide nonattainment areas, such as that portion of New York included
in the ``New York-Northern New Jersey-Long Island'' carbon monoxide
nonattainment area, to submit a SIP revision that forecasts vehicle
miles travelled through the year 1995. In addition, annual reports and
annual updates are required by the State.
The vehicle miles travelled forecast must meet several
requirements. It must estimate the vehicle miles travelled from 1990
through 1995 using a method acceptable to EPA, must be conducted in the
appropriate geographic area and must provide for annual updates of the
forecasts and annual reports on the extent to which the forecasts were
accurate, as well as estimates of actual vehicle miles travelled in
each year for which a forecast was required (57 FR 13532, April 16,
1992). Moreover, the state should develop the vehicle miles travelled
forecast based on EPA guidance.
Contingency measures are to be implemented in a case where the
actual annual vehicle miles travelled or the updated forecast contained
in an annual report exceeds the most recent prior vehicle miles
travelled forecast by an acceptable margin of error (5.0 percent in
1994, 4.0 percent in 1995, and 3.0 percent thereafter) and/or if
estimated actual vehicle miles travelled or forecasted vehicle miles
travelled exceeds a cumulative 5 percent cap above the attainment
demonstration.
The estimated vehicle miles travelled for 1990 and 1991 are 130.7
and 134.6 million miles per day, respectively. In addition, the future
forecasts were (in million miles per day) 138.5 for 1992, 142.5 for
1993, 146.4 for 1994, and 150.3 for 1995.
On November 15, 1994, New York submitted a vehicle miles travelled
tracking report for the State's 1992 New York City Metropolitan area
Carbon Monoxide SIP. This report showed that for 1990, the actual
vehicle miles travelled was 130.8. The actual vehicle miles travelled
for 1991 to 1993 were below the original forecast: 131.8 for 1991;
135.8 for 1992 and 137.1 for 1993.
New York has submitted documentation satisfying these requirements
and EPA, therefore, proposes approval of New York's vehicle miles
travelled forecast SIP revision.
Contingency Measures
Section 187(a)(3) of the Clean Air Act requires that states adopt
contingency measures to take effect without further action by the
Administrator or the state if the state fails to attain the NAAQS by
the required date or if any estimate of actual vehicle miles travelled
in the nonattainment area or any updated forecast of vehicle miles
travelled contained in an annual report for any year prior to
attainment is exceeded beyond the allowable limit as discussed in the
vehicle miles travelled forecast section. Contingency measures should
be capable of reducing vehicle miles travelled or resultant emissions
by an amount equal to the projected annual growth rate for vehicle
miles travelled (57 FR 13532, April 16, 1992). New York identified two
contingency measures, the employee commute option program and winter
gasoline volatility reductions, to fulfill this requirement. These
programs would both act as contingency measures for failure to attain
the carbon monoxide standard or for exceeding the vehicle miles
travelled forecast.
Employee Commute Option Program
New York is required by section 182(d)(1)(B) of the Clean Air Act
to submit its Employee Commute Option program as part of its ozone
nonattainment SIP. New York's program applies to employers with 100 or
more employees who arrive at the workplace between the hours of 6 and
10 a.m. The goal of this program is to increase the average passenger
occupancies by 25above the average for all vehicles arriving to all
workplaces within the zone. This would decrease the amount of
automobiles arriving at the workplace, and therefore, decrease the
vehicle miles travelled.
New York enacted enabling legislation on August 9, 1993 and the New
York State Department of Transportation adopted regulations on April 6,
1994 to implement the program. New York then submitted a SIP revision
on June 6, 1994 that contained an adopted employee commute option
program. EPA will be taking action on the employee commute option
program submittal as a requirement of the ozone SIP in a separate
Federal Register notice since there are specific requirements an
employee commute option program must meet for an ozone SIP but not for
contingency measures in a carbon monoxide SIP.
Winter Time Gasoline Volatility
New York identified Winter Time Gasoline Volatility as an
additional contingency measure. New York State's Subpart 225-3 ``Fuel
Composition and Use--Volatile Motor Fuel'' permits the commissioner to
set a winter RVP level for gasoline if such a level is necessary for
air quality purposes. This regulation was adopted on June 30, 1993.
EPA is proposing to approve the State's use of the winter time
gasoline volatility program as a carbon monoxide contingency measure
because it is an adopted measure that will serve to reduce emissions of
carbon monoxide. Also, section 211(c)(4) does not preempt the State
from adopting a limit on gasoline RVP in the winter time. Under section
211(c)(4), states are preempted from prescribing any control or
prohibition respecting any characteristic or component of a fuel, where
there is a nonidentical Federal control or prohibition applicable to
such characteristic or component. There are two sources of Federal
controls on RVP, the Phase II Federal RVP controls promulgated under
section 211(h) and section 211(c)(1), and the Federal RVP controls for
reformulated gasoline promulgated under section 211(k) and section
211(c)(1). Both of these Federal RVP controls apply only in the summer
months. There is no Federal RVP control applicable to gasoline in the
winter time, and thus no Federal preemption of the New York winter time
RVP control.

Although New York identified two acceptable contingency measures,
only one is approvable by EPA at this time. Therefore, EPA proposes to
approve the winter time gasoline volatility program as an adequate
contingency measure should New York fail to attain the carbon monoxide
standard or exceed the vehicle miles travelled forecast. Action on the
employee commute option program will be taken in a separate Federal
Register notice.
Carbon Monoxide Emission Inventory
New York submitted a carbon monoxide emission inventory on November
15, 1992 as required by section 187(a)(1) and as described in section
172(c)(3) of the Clean Air Act. Additional inventory information was
submitted in January and March of 1993.
The emission inventory is for a typical carbon monoxide season
weekday occurring during December, January, and February and represents
a comprehensive, actual inventory of all carbon monoxide emission
sources in the New York Metropolitan area. It includes emissions from
point, area, and mobile sources (see 1990 base year carbon monoxide
emissions summary in Table 1).
