Emissions Regulations – NSPS and regional regulations National
– EPA defines minimum standards and rules for the U.S.• New Source Performance Standards, Nonroad Source Rules• National Air Quality Attainment Requirements
States or Local– State Specific Standards (at least as strict as EPA)
• Permits– Critical Area Rules: Non-attainment, Parks, BLM etc.
Caterpillar Confidential: Green
National - SI NSPS and NESHAP SI NSPS : (Stationary) Spark Ignited New Source
Performance Standards– Published January ’08, Effective March ’08.– 1st New engine requirements retroactive to July ‘07.– 1st Remanufactured or Modified (RM) engine requirements
retroactive to June ’06.– Applies to new, reconstructed or modified stationary
engines.– Based on the date of engine manufacture, reconstruction
or modification, not the date of installation.
Caterpillar Confidential: Green
National - SI NSPS Emissions Standards
– There are alternate ppm values that may be advantageous depending on engine efficiency.
– There are standards for other applications as well. (ie. Landfill, etc.)
NOx / CO / VOC (g/hp-hr) 200612-Jun 1-Jul 1-Jul 1-Jul

Caterpillar Confidential: Green
National - NESHAP and SI NSPS NESHAP : National Emissions Standards for
Hazardous Air Pollutants– Update to existing rule published January ’08, Effective
March ’08.– Existing requirements back to ’02. – Applies to new or reconstructed stationary engines.
• Are working on applying rule to all existing stationary engines.– Newly regulated engines only have to meet SI NSPS.
Caterpillar Confidential: Green
NESHAP Notice of Proposed Rule Making
National Emission Standards for Hazardous Air Pollutants for Reciprocating Internal Combustion Engines; Proposed Rule change.– Would change 40 CFR 63, subpart ZZZZ
Regulates all previously unregulated SI and CI existing and new stationary engines.– Intended to drive the use of Catalysts – Adds Startup, Shutdown and Malfunction Requirements– Adds Mandatory Maintenance Requirements
Over 180 comments were submitted.

NESHAP Notice of Proposed Rule Making
Caterpillar Confidential: Green
NESHAP Notice of Proposed Rule Making HAPs - ~188 regulated compounds
– Represented by a surrogate: Typically Formaldehyde, CO or VOC
Major Source – @ site, 10 tons/yr single HAP, or 25 tons/yr all HAPs
Area Source – Anything that is not a Major Source
SS SSM SS SSM SS SSM SS SSM
>=500 hp P P P P
<500 hp P P P P
SS Steady StateSSM Startup, Shutdown & Malfunction
Already regulated under existing NESHAP.P Proposed to be regulated under new NESHAP changes.
Not directly regulated, but steady state requirements apply as written.

Example of Proposed NESHAP Ruling– G3406 NA Engine purchased in 1996
– 215 bhp at 1800 rpm Rich Burn
– Area Source Compression site anywhere in the USA
– Requires change from Standard “Best Efficiency” to Catalytic setting
– Normal operation
– 40CFR60 JJJJ
– 40CFR63.6590c
– Startup, Shutdown & Malfunction

State Emissions Highlights
– Colorado, East Slope (Denver Area) Nonattainment
– Wyoming, Sublette County
– New Mexico, Aftertreatment Permits
– Texas, HGB Nonattainment
– Regional Regulation Activity
Caterpillar Confidential: Green
Colorado, East Slope (Denver Area) Non-attainment Area
The Denver area did not meet the federal 8 hour Ozone requirements– Colorado submitted a State
Implementation Plan (SIP) that shows compliance by 2012
Caterpillar Confidential: Green
Colorado, East Slope (Denver Area) Non-attainment Area
New Rule– New, modified or relocated-into-the-state SI ICE must
meet the SI NSPS emissions standards in place when the installation occurs.
– Existing RB ICE >500 hp must have 3 way catalysts, and Air/Fuel controllers by May 1, 2010.
– Existing LB ICE >500 hp must have oxidation catalysts by May 1, 2010, unless they are built before June 1, 2004 and the retrofit costs more than $5000/ton VOC.
– Engines regulated under 40 CFR 60, or operating under MACT or BACT requirements are excluded.
Caterpillar Confidential: Green
New Mexico Changes “Notice of Intent” Permit Policy
– Previously did not count aftertreatment in their consideration of “potential emission rate”.
– Aftertreatment used in meeting the CI NSPS, SI NSPS or NESHAP will now be accepted.
– Limits the number of engines that need to go through the full air permit process.
New Mexico
Caterpillar Confidential: Green
Wyoming Interim Permit Policy in
Sublette County– 1 Measurement > Ambient
NOx standard– Effectively caps VOC and
NOx Emissions– Requires reduction of 1.5:1
for VOC, and 1.1:1 for NOx Still Working on Permanent
Measures– Gas engines to replace
diesel engines in drill rigs– SCR in diesel drilling
application– Regulation of Diesel Engines
as Stationary
Caterpillar Confidential: Green
Texas, HGB Nonattainment
The Houston Area has been redesignated as a Severe Nonattainment area.– SIP update by 4/15/10.– Mandatory CAA
compliance by 6/15/19– New rules for engines in
the area likely.
HGB – Houston-Galveston-Brazoria
Caterpillar Confidential: Green
Regional Regulation Activity Marcellus Shale
– Just now evaluating potential air quality impacts.
– Initial focus is on limiting drilling emissions.
Oklahoma & Arkansas – SI NSPS is enough for
now.
Four Corners Task Force – National engine emission rules will
improve air quality without other measures.
– Adding 3-way catalysts to existing RB engines is the only engine measure that showed other significant improvement.
Caterpillar Confidential: Green
Key Summary Points Emission Regulations – Review of NSPS & regional regulations National Regulations
– NSPS• Applies to every new engine• Based on born on date• Next key date is July 1st, 2010
– NESHAP• Proposed plan has not been finalized• Based on start up date• Next key date is February 10th, 2010
States or Local– Typically more strict than National Regulations– Non – Attainment Areas
