Haynesville Shale Mobile Source Emission Inventory
• Heavy-duty diesel trucks transporting water and
materials to and from Haynesville well sites may be
an important source of NOx emissions
– Not included in NETAC’s Haynesville emission inventories
• Trips can occur on rural public roads and on private
roads
– Trips may not be fully accounted for in current on-road
mobile source emission inventories
• Study aims to characterize the magnitude of these
emissions by developing a new Haynesville Shale
mobile source inventory
– Is this a significant source of emissions?
2
Method and Status
• 2012 emission inventory year
• Survey developed, approved by NETAC Technical
Committee, and sent to 14 producers in April, 2013
– Email/phone followup
– 1 survey has been returned
• Now reviewing other studies to provide additional
•
information on truck traffic associated with natural
gas production
Develop emission inventory
– Assess significance of on-road mobile in relation to other
Haynesville sources
• Incorporate inventory into NETAC’s ozone modeling
3
Control Strategy Evaluation
• Develop a list of potential emissions control measures to be
evaluated with NETAC’s ozone models
• To be creditable in a SIP, emissions reductions must be:
–
–
–
–
Permanent
Federally enforceable
Surplus
Quantifiable
• Voluntary local measures that do not meet these criteria
can be considered
• Request that operators of large EGU/industrial sources
contribute description of potential emission controls for
their facilities
• Ozone Advance Path Forward Document
4
Ozone Modeling
• Reduce high bias in modeled ozone
– More accurate simulation of transported versus local
contribution
– Sensitivity tests
– AQRP project
• Re-run episodes using source apportionment to confirm
relative importance of source regions and emission source
categories
• Use modeling and emissions study results to develop
control strategy evaluation report that can inform NETAC’s
Ozone Advance Path Forward Letter
– CAMx runs to guide control strategy development
 What is the effect of reducing emissions from a particular emissions
category on Northeast Texas ozone?
• Final report
5
Other Tasks
• Conceptual model update through the 2012
ozone season
– Analysis underway, report completed by fall 2013
• Review of TCEQ point, area, off-road emission
inventories for 2008
– Analysis completed, report in progress
