Subject: Transportation Conformity
The Clean Air Act requires that all transportation projects that use federal money must show that
they conform to the State Implementation Plan's{SIP) emission budget for those air pollutants
where we have not yet achieved the ambinet air quality standard. As part of the transportation
planning process, both the transportation plans and the individual projects must show that they
confirm to the SIP. There are many steps involved, including modeling the emissions from the
transportation sources.
The Clean Air Act lays out various timeframes and requirements concerning conformity. If the
transportation plans or projects cannot be shown to confirm to the SIP, federal money is frozen.
With the massive change in traffic and traffic patterns in lower Manhattan, a new transportation
network model has to be put together and NYS is requesting an extension of the submission date
for the next conformity determination to address these changes. In addition, NY's transportation
coordination agency, which is responsible for preparing the transportation plans and the
conformity work, was housed in the WTC. Three of their staff were lost and a wealth of
information.
DEP follows the transportation planning issues from a distance these days. Citywide, the lack of
a funded transportation plan has a big impact on the transportation agencies and could have
indirect negative impacts on air quality.
DEC will explain this more, I'm sure.
