Announcement of Public Comment Period for
Draft Transportation Conformity Determination
for 2014-2018 TIP and 2014-2040 Regional Transportation Plan, As Amended
Monday, October 5, 2015 through Wednesday, November 4, 2015.
NYMTC has prepared a draft Transportation Conformity Determination for the 2014-2018 Transportation Improvement Program (TIP) and the 2014-2040 Regional Transportation Plan (Plan 2040). This draft Conformity Determination is in accordance with U. S. Environmental Protection Agency regulation 40 CFR 93 Subpart A; and is being issued in response to the adoption of a new Regional Transportation Plan by the Orange County Transportation Council (OCTC). Part of NYMTC’s planning area and all of OCTC’s planning area are in the Poughkeepsie Ozone Non-Attainment Area, which means that NYMTC and OCTC must coordinate their air quality activities. The public comment period will begin on Monday, October 5, 2015 and end at 4 pm Wednesday, November 4, 2015. The comment period provides the opportunity for public feedback on the draft Transportation Conformity Determination.
A Transportation Conformity Determination contains a regional emissions analysis for mobile sources as required by the Clean Air Act of 1990 for designated non-attainment areas (i.e., areas that do not attain National Ambient Air Quality standards for pollutants identified in the Clean Air Act Amendments of 1990. A Conformity Determination must be adopted for all Transportation Improvement Programs and Regional Transportation Plans in non-attainment areas to demonstrate how forecasted emissions levels conform to emissions milestones established by the New York State Implementation Plan for Air Quality.
Please note that there have been no changes to non-exempt transportation projects – those projects that must be included in a regional emissions analysis under the Clean Air Act Amendments of 1990 – contained in NYMTC’s TIP or in Plan 2040 since NYMTC last adopted a Transportation Conformity Determination on December 4, 2014.
Written comments will be accepted through 4 pm on Wednesday November 4, 2015.

Approved Conformity Determination for
2014-2018 TIP and Plan 2040
This NYMTC Transportation Conformity Determination for the 2014-2018 Transportation Improvement Program (TIP) and the Plan 2040 (Plan) contains a regional mobile source emissions analysis that reflects compliance of the TIP and Plan with the mobile source emissions requirements under the Clean Air Act of 1990 and the New York State SIP for designated non-attainment areas. The determination was conducted with the United States Environmental Protection Agency’s Motor Vehicle Emission Simulator, and the transportation conformity determination was approved by USDOT on April 06, 2015.
About Transportation Conformity

Transportation conformity is the process established by USDOT and USEPA to ensure that transportation investments will contribute to improving air quality in areas where pollutants exceed National Ambient Air Quality Standards (NAAQS). The areas are known as non-attainment areas and are designated by USEPA. All states with non-attainment areas must produce a State Implementation Plan (SIP) for the attainment of NAAQS within their state. Every MPO TIP and RTP must show compliance with the motor vehicle emissions budgets defined in the SIP.
NYMTC’s Conformity Determination Process through it’s regional emission analysis, demonstrates how the regional transportation plan and transportation improvement program contributes to meeting targeted reductions of mobile sources of air pollution for the attainment of National Ambient Air Quality Standards. The regional emission analysis focuses on three important sources of air pollution, ground-level ozone, carbon monoxide and particulate matter. The Conformity Determination shows how NYMTC is meeting targeted reduction of the precursors of ozone, NOX and VOC’s, required by the motor vehicle emissions budgets defined in the New York State Implementation Plan for air quality. It also indicates that regional concentrations of carbon monoxide are below required maintenance levels.
DSNY now operates about 800 alternative fuel vehicles, including some that use compressed natural gas (CNG) as well as a sizeable fleet of E85 flexible fuel vehicles.
Smog or ground-level ozone is formed when vehicles emit nitrogen oxides (NOX) and volatile organic compounds (VOC’s) in the presence of sunlight. Since the chemical reactions that create ground-level ozone work best during warm weather this problem is most pronounced during the summer and the analysis is performed during peak season to measure the worst case scenario.
Carbon monoxide is produced by the incomplete burning of carbon in fuels, including gasoline. High concentrations of carbon monoxide occur along roadsides in heavy traffic, particularly at major intersections and in enclosed spaces, such as garages. Peak concentrations of carbon monoxide typically occur during the winter months and the analysis is performed during this peak to measure the worst case scenario.
Soot, technically known as particulate matter or “PM” is typically generated by diesel engines or by unregulated combustion. Fine Particle matter, also known as PM2.5, is a mixture of microscopic solids and liquid droplet suspended in the air, where the size of the particles are less than 2.5 micrometers, or about one-thirtieth the diameter of a human hair. PM2.5 can be emitted directly into the air, from smoke from fires or as a component of automobile exhaust. It can also be formed in the air itself, from industrial and mobile source emission of gases, such as sulfur dioxide and nitrogen oxides.
