Is Your Stationary Engine Compliant?

In 2010, the US EPA ruled on the National Emission Standards for Hazardous Air Pollutants or NESHAP for Reciprocating Internal Combustion Engines (RICE). The ruling affects existing stationary compression ignition and spark ignition engines and seeks to reduce emissions of toxic air pollutants, such as formaldehyde, from several categories of previously unregulated stationary engines. In certain cases, the EPA ruling allows carbon monoxide (CO) to be a surrogate for the hazardous air pollutants. The RICE NESHAP regulations have been enforced beginning in May 2014.

RICE NESHAP Requirements

The affected stationary compression ignition engines must comply with CO emission limits or must be fitted with emission controls, such as diesel oxidation catalysts, to reduce CO emissions by at least 70%. The ruling also requires the use of ultra-low sulfur diesel fuel for stationary non-emergency, non-black start engines greater than 300 hp with a displacement of less than 30 liters per cylinder. The ruling also includes a number of additional provisions, including start up and maintenance requirements. Stationary engines greater than or equal to 300 hp must also be equipped with closed or open crankcase filtration system in order to reduce metallic HAP emissions. The ruling requires initial and continuing compliance that includes monitoring, data logging, and performance tests at specific intervals.

Engines Affected by the EPA RICE NESHAP Ruling

  • Any existing, new, or reconstructed stationary RICE located at a major or area source of HAP emissions.
  • The ruling includes compression and spark ignition, non-emergency and emergency, peak shaving and standby power generation, pumping stations, and various other types of stationary RICE.
  • The ruling differs based on the classification of the engine; FME can help you through determining the applicable requirements for your specific engine.

Fairbanks Morse Engine Can Help You Comply with RICE NESHAP

Diesel Oxidation Catalyst (DOC) and Crankcase Ventilation (CCV)

A diesel oxidation catalyst (DOC) and a crankcase ventilation (CCV) system from Fairbanks Morse Engine will help make existing compression ignition engines RICE NESHAP compliant. We will guide you through the process, from sizing and design to unit installation and monitoring, and help ensure that your site is RICE NESHAP compliant with equipment designed and installed per your unique requirements. An "off the shelf" product may not fit or could be more expensive than you need.

Testing and Site Evaluation

We have the capabilities to help you evaluate your facility and emission sources and to gather the necessary data for RICE NESHAP compliance. This includes backpressure measurements, installation options, and temperature and emissions requirements. Our Sales Team will conduct a complete on-site evaluation at your request and at no charge to you.

Monitoring and Controls

We will also provide a comprehensive data logging monitoring system for easy documentation of requirements for RICE NESHAP reporting. Documentation will include catalyst inlet temperature and pressure drop across the catalyst per the requirements of the ruling. Several different monitoring and data logging options are available and can be customized to fit your specific requirements.

Information and Recommendations

We also offer technical guidance, interpretations of regulations, and evaluation of engine performance and emissions output to make it easier for you to decide on the right solution for making your site RICE NESHAP compliant. You will have access to all our engine and RICE NESHAP technical expertise. We stand committed to ensuring that your site is initially compliant and maintains compliance. We are also available for long term maintenance, testing, and compliance activities.
