Following the designation of an area as non-attainment for the criteria
pollutant Ozone, the Clean Air Act requires submission of an
implementation plan, commonly referred to as State Implementation Plan
(SIP), demonstrating as to how that area will be meeting the NAAQS in
the time period established by the Act. Several areas of the OTR were
designated as being in nonattainment for 8-hr ozone (see   HYPERLINK
"http://www.epa.gov/ozonedesignations/" 
http://www.epa.gov/ozonedesignations/ ) with a maximum attainment date
of June 2009 and June 2010. However, given that ozone precursors also
contribute to PM2.5 and other logistics, it was recommended and agreed
by the member states that the future year for demonstrating attainment
would be 2009. Therefore the OTR states initiated the development of
emissions inventories reflecting growth and control from 2002 to 2009 as
well as for 2012 and 2018. The 2018 inventory was in response to the
need for submission of regional haze SIP, and the 2012 as a next step in
the event that attainment for ozone was not feasible in 2009. 

Future year emissions inventories within the OTR

The OTR states through MANE-VU contracted MACTEC Federal Programs
(called Contractor) develop the 2009, 2012 and 2018 inventories based
upon 2002 inventories that the states had previously developed for use
in the base year model work. The Contractor in consultation with the
states developed the necessary growth and control factors and applied to
the 2002 inventory. It should be noted that emissions for mobile sources
and the electric energy generating units (EGUs) was not part of the
Contractor’s effort. The states provided VADEQ and NESCAUM appropriate
MOBILE 6 input files along with the projected VMTs, which coupled with
the hourly gridded temperature information was used to generate mobile
source emissions. As for the emissions from the EGU sector, the
inter-RPO work group utilized the Integrated Planning Model (IPM) to
develop the state and unit-level emissions. Details on these topics can
be found in MACTEC (2007) for non-EGU sectors and in ICF (2005a, 2005b)
for the EGU sector. These inventories are identified as 2009 on the way
(2009OTW), since they reflect all emission control measures that were
promulgated or would become effective on or before 2009. 

In addition to these OTW inventories, states have also requested the
development of what is termed as beyond on the way (BOTW) inventories
for 2009, 2012, and 2018. These inventories are to be based on
additional OTC model rules, which would result in reduction in emissions
from specific source categories. Details on the development of these
controls and the corresponding inventories can be found in MACTEC
(2007).

Future year emission inventories outside the OTR

MANE-VU obtained inventories for 2009OTW and 2018OTW as part of the
inter-RPO workgroup. However, only MRPO provided emissions for 2012OTW.
For the VISTAS region, 2012 emissions were obtained by interpolating
area, nonroad, and non-EGU emissions between 2009 and 2018. For mobile
sources, VMT were interpolated between 2009 and 2018 and the 2012
emissions were calculated with MOBILE6 using these interpolated VMT and
2012 emission factors. For the CENRAP region, no 2012 emissions were
generated, and therefore the 2009 emissions were used in the 2012 CMAQ
simulation.

Canadian Emissions

In the case of Canadian emissions, 2010 and 2020 area, non-road, and
mobile source emissions were obtained from USEPA (  HYPERLINK
"ftp://ftp.epa.gov/EmisInventory/canada_2000inventory/" 
ftp://ftp.epa.gov/EmisInventory/canada_2000inventory/ ). 

Primary PM2.5 and PM10 emissions for the SCCs listed in   HYPERLINK
"http://www.epa.gov/ttn/chief/emch/invent/tf_scc_list2002nei_v2.xls" 
http://www.epa.gov/ttn/chief/emch/invent/tf_scc_list2002nei_v2.xls  were
divided by a factor of 4 to account for the fugitive dust transport
fraction correction. EGU point source emissions for 2010 and 2020 were
obtained from Environment Canada (Bloomer, 2006), while non-EGU point
source emissions were assumed to be the same as those developed for 2002
and described elsewhere (see TSD-1c). The 2010 inventories were used in
preparing CMAQ input files for the 2009OTW, 2009BOTW, and 2012BOTW
scenarios.

Emissions processing – Application of SMOKE

The 2009OTW, 2009BOTW, and 2012 BOTW inventories were processed by VADEQ
and NYSDEC using a template similar to that was used for processing 2002
base year emissions (see TSD-1d, TSD-1j) for the 12 km domain. In
particular, all gridding and speciation profiles and cross-reference
files as well as all temporal allocation profiles and cross-reference
files used in the 2002 processing were also used for future year
processing.  For each day, the following files were prepared:
