5. Title, number of pages and language(s) of the notified document:   Standards of 
Performance for Stationary Compression Ignition Internal Combustion Engines 
(35 pages, in English). 
6. Description of content:   This action proposes standards of performance for stationary 
compression ignition (CI) internal combustion engines (ICE).  These standards implement 
section 111(b) of the Clean Air Act (CAA) and are based on the Administrator's determination that stationary CI ICE cause, or contribute significantly to, air pollution that 
may reasonably be anticipated to endanger public health or welfare.  The intended effect of 
the standards is to require all new, modified, and reconstructed stationary CI ICE to use the 
best demonstrated system of continuous emission reduction, considering costs, non-air 
quality health, and environmental and energy im pacts, not just with add-on controls, but 
also by eliminating or reducing the formation of these pollutants.  The proposed standards 
would reduce nitrogen oxides (NOX) by an estimated  38,000 tons per year (tpy), particulate 
matter (PM) by an estimated 3,000 tpy, sulfur dioxide (SO2) by an estimated 9,000 tpy, 
non-methane hydrocarbons (NMHC) by an est imated 600 tpy, and carbon monoxide (CO) 
by an estimated 18,000 tpy in the year 2015. 
7. Objective and rationale, including the na ture of urgent problems where applicable:
