SUBJECT:	Summary of the November 19, 2009 Teleconference with the Engine
Manufacturers Association and the U.S. Environmental Protection Agency
to Discuss Crankcase Emissions from Stationary Compression Ignition
Engines

1.0	INTRODUCTION

EPA requested this meeting with the Engine Manufacturers Association
(EMA) to discuss control options for crankcase emissions from existing
stationary compression ignition (CI) engines to be regulated under 40
CFR part 63, subpart ZZZZ.  This meeting summary will be available in
the docket for this rulemaking (Docket ID No. EPA-HQ-OAR-2008-0708). 
The proposed rule for existing stationary RICE was published in the
Federal Register on March 5, 2009 (74 FR 9698).

3.0	SUMMARY OF MEETING

EPA assembled the meeting to discuss control options for crankcase
emissions from existing stationary CI engines.  EPA asked EMA if closed
crankcase ventilation would be a suitable option for reducing metallic
HAP from existing stationary CI engines.  EMA said that only Korea
requires crankcase ventilation systems and the requirements are only for
mobile sources.  Further, EMA stated that in the U.S. pre-2007 emission
requirements do not require the use of closed crankcase ventilation. 
According to EMA, older engines have higher blowby emissions, due to
wearing of the piston rings and seals.  In addition, installation of a
closed crankcase ventilation system reduces fuel economy by
approximately 3-5% and can reduce the rated power of the engine, EMA
said.  Other issues with the installation of closed crankcase
ventilation include condensation of the collected blowby gases, freezing
of the ventilation system in cold climates, and the system cannot be
used on larger engines, according to EMA.  EMA stated that several of
the engine manufacturing companies have open or closed crankcase
ventilation products that can be used on 1993-2004 model year engines.  

EMA stated that it would discuss the options that are available with EMA
members and send a recommendation to EPA.
