NESHAP-RICE National Emissions Standards for Hazardous Air Pollutants for Reciprocating Internal Combustion Engines (NESHAP-RICE) have been formulated, but are currently being re- considered, in response to public comments. The Iowa Association of Municipal Utilities (IAMU), Minnesota Municipal Utilities Association (MMUA), and Central Minnesota Municipal Power Agency CMMPA) have forwarded comments on these proposed rules to the Environmental Protection Agency (EPA). The date for an EPA ruling on these comments is unknown. The new regulations state that by 8/31/2010, an Initial Notification to the EPA was required, regarding the affected sources. Information required: manufacturer, model #, serial #, KW rating, facility name, facility address, manufacture date, This notice required a listing of all owned diesel-generators, including the application: emergency only, peak shaving, available capacity, storm avoidance, etc.; and engine/generator and installation date. ERMU did provide the requested information to the EPA on time. The engine/generators not affected are emergency-only or newer than 6/12/2006 (which are required to meet the NESHAP standards.) The units affected are stationary diesel engine electrical generating units, greater than 500 hp, used for non-emergencies, and older than 6/12/2006, that do not meet NESHAP emission limitations. All four of ERMU's engines, at the power plant, do not meet the new emissions limitations. The proposed new standards state that if a unit is designated an emergency unit without new emissions controls, the unit could run: (a) 100 hours/year for readiness testing; (b) no limits on hour during outages on the interconnection; 4
