MOVES2014 October Release
As many of you are aware, we released MOVES2014 in July of 2014. We would like to thank the user
community for the early feedback. We received some positive feedback, and some suggestions for
improvement. Since the release, users have identified a number of suspected problems in the model. The EPA
MOVES team has been investigating these concerns and, as necessary, working to improve the model.
We have now posted an updated version of the MOVES2014 Installation Suite that fixes a significant error in
the new nonroad portion of MOVES2014. We also took this opportunity to address a number of minor issues
with the onroad portion of MOVES2014. This update also improves the installation process and includes
small performance improvements. Finally, we have fixed an error in the spreadsheet that some states use to
estimate evaporative emissions from vehicles meeting California Zero Emission Vehicle (ZEV) standards.
We are referring to this update as the MOVES2014 October Release. All MOVES2014 users should install the
MOVES2014 October Release as soon as possible. The new code and database are now available on the
MOVES website: www.epa.gov/otaq/models/moves/. The new ZEV spreadsheet is available at
http://www.epa.gov/otaq/models/moves/tools.htm .
All MOVES2014 guidance, as well as the contents of the Federal Register Notice of Availability for
MOVES2014 (www.gpo.gov/fdsvs/pkg/FR-2014-10-07/pdf/2014-23258.pdF). apply to the MOVES2014
October Release.
Below is a list of the improvements in the MOVES2014 October Release. Note that if you did any previous
runs with the July version of MOVES2014 which did not include nonroad output and are not affected by any
of the onroad issues listed below, you may continue to use that output. However, you should still install the
MOVES2014 October Release for all future work with MOVES.
Thanks,
The MOVES Team

Repair to Nonroad

Nonroad emissions will
increase by factor of about
30 with the fix.

NONROAD2008 can continue to be
used as well.

Repair to Nonroad
population problems
High for
users
calculating
Nonroad
rates from
activity
output.
None for
users of
Nonroad
inventory
results.
No impact on direct
emissions output from
MOVES2014, but some
post-processing scripts
calculated incorrect rates
because of artificially
inflated population and
activity output. In
addition, some scripts
incorrectly handled
population when multiple
days and months were
selected.
Equipment population and source
hours in MOVES activity output
will drop by a factor of two with the
fix. Rates calculated by the post-
processing scripts will drop by a
factor of two or more, depending on
the number of days and months
selected.
A fix for a problem
with the emission rate-
per-hour emissions for
Auxiliary Power Units
(APUs).
Low
Corrects an error in rates
that occurs only when
"model year" was not
checked in the output detail
pane. This error does not
affect inventory output or
output to other rates tables.
The addition of missing
pollutants to the
RatePerDistance,
RatePerHour and
RatePerProfile output
tables.
RatePerDistance was
missing NO and
HONO. RatePerHour
was missing NO,
HONO and all
emissions for
Crankcase Extended
Idle Exhaust.
RatePerProfile was
missing the CB05
chemical species
Low
These emissions are
important for users
preparing lookup tables for
use in air quality modeling.
This does not affect
inventory output or output
for other pollutants.

A change to the
Sample VehiclePopulati
on table that repairs an
error in the sourcetype
fractions for long-haul
single unit trucks and
short-haul combination
trucks (SourceTypes 53
and 61)
Low
This error sometimes
caused incorrect results
when using the Alternative
Vehicle and Fuel
Technologies (AVFT)
importer to change the fuel
mix for these sourcetypes.
Users not importing local
AVFT tables are
unaffected.
A change to the
PollutantProcessAssoc
table so MOVES now
correctly requires users
to model PM2.5
running processes
whenever requesting
output of brakewear
emissions
Low
Without this fix, some
runs where users
requested brake wear
lacked these emissions.
Users requesting brake
wear emissions plus
PM2.5 running emissions
are unaffected.
A code change that
does not allow separate
ramp output for "rates"
runs.
Low
Emission rates (per -
vehicle, per-profile) were
incorrect in runs that
requested output
specifying "ramp"
roadtypes. Rate runs that
did not request "ramps" as
separate output were
unaffected. Inventory
runs were unaffected.
With the fix, users may not request
separate ramp output in "rates"
runs. Separate ramp output
continues to function for inventory
mode.
A change to allow
output Chemical
Mechanism CBO5
pollutants for crankcase
extended idle,
crankcase start exhaust
and crankcase running
exhaust emissions.
Low
These emissions are very
small and are relevant only
for users preparing output
for use in air quality
modeling.
There was no output for these
pollutant/process combinations
before the fix.

Notes
A fix to a divide-by-
zero error for Nonroad
runs of the 1990, 1999
and 2000 calendar
years.
Low
Incorrect emissions were
produced when a user
modeled calendar year
1990, 1999 or 2000 and
did not select all
pollutants.
Before the fix, the model also
logged an error in the error output
table.
Diesel refueling
displacement vapor
loss set to zero.
Low
Diesel refueling
displacement vapor loss
was incorrectly reported.
It is now correctly set to
zero.
Change in fuel supply
to correctly increase
RVP of El 5 fuels in
RVP control areas
without E10 waivers.
Low
The change increases
evaporative emissions
from E15 fuels in affected
areas. It also causes very
minor changes in exhaust
emissions.
An improvement to the
default fuel supply to
assure that every
county has a default
Compressed Natural
Gas (CNG) fuel.
None
This will prevent a "red X" in the
Fuels Importer if the user chooses
CNG in the Runspec and imports
the default fuel supply.
A code change so that
users running MOVES
from the command line
do not get an error
when using the "-rl"
command to automate
the running of a list of
runspecs.
None
The change allows the use of-rl in
command line runs.
A change to the
DataSource table to
remove zeros.
None
The change prevents an error message
during actions such as server-to-
server copying.
-------
Change
An improvement to the
Nonroad post-
processing scripts.
A change to the
message provided
when users open the
MOVES2010b
converter that clarifies
that additional work is
required before using
converter output with
MOVES2014.
Change to I/M database
to give unique
program-IDs to
alternative fuels.
Improvement to
increase speed for
processing large runs.

Notes
The change clarifies the unit
labeling and fixed a bug that
occasionally reported false errors
after a post-processing script
successfully completed.
Provides clearer instructions for
using the MOVES2010b converter.
This change has no impact on
emissions but reduces the chance of
confusion.
Very large runs with many worker
"bundles" now run more quickly.
The change repairs an error that
caused failures when trying to run
multiple workers.

Notes
With MOVES2014, EPA provided a tool
to help model emissions in states that
adopted California Low Emission Vehicle
(LEV) standards. This included a
spreadsheet
(ZEV_AVFT_MOVES2014.xlsx) to help
estimate evaporative emissions from Zero
Emission Vehicles (ZEVs). A problem
with the spreadsheet led to an error when
users attempted to import data from the
sheet. It has been fixed.
The new spreadsheet is not part of
the October Release installation
suite. It is available with the other
LEV tools at
http : //www .epa. gov/otaq/models/m
oves/tools.htm
The old path caused failures when
running Nonroad in MOVES with
the Windows XP operating system.
Note that the MOVES2014
Software Development Reference
Manual document is not available at
this time, therefore you may still see
a "page not found" error for this
report.
The new instructions should help
users resolve firewall issue on
computers that sometimes block
MySQL installation
