6. Description of content:  Proposed rule - The Environmental Protection Agency (EPA) is 
proposing to amend the National Emission Standards for Hazardous Air Pollutants 
(NESHAP)  for Reciprocating Internal Combustion Engines (RICE), the New Source 
Performance S tandards (NSPS) for Stationary Compression Ignition (CI) Internal 
Combustion Engines, and the NSPS for Stationary Spark Ignition (SI) Internal Combustion 
Engines, to add electronic reporting provisions. The addition of electronic reporting 
provisions will provide for simplified reporting by sources and enhance availability of data 
on sources to the EPA and the public. In addition, a small number of clarifications and 
corrections to these rules are being proposed to correct inadvertent and other minor 
errors  in the Code of Federal Regulations (CFR), particularly related to tables. Finally, 
information is being solicited on the provisions specifying that emergency engines can 
operate for up to 50 hours per year to mitigate local transmission and/ or distributi on 
limitations to avert potential voltage collapse or line overloads that could lead to the 
interruption of power supply in a local area or region.  
7. Objective and rationale, including the nature of urgent problems where
