Is Your Natural Gas Powered Stationary Engine Compliant to
EPA's RICE NESHAP 2013?

In August, 2010, the EPA provided a final ruling on National Emission Standards for Hazardous Air Pollutants (NESHAP) for Spark Ignited Reciprocating Internal Combustion Engines (SI RICE). This ruling effects existing stationary diesel engines. Final compliance is October 19, 2013. However, an initial notification of applicability needs to received by the EPA before February 16, 2011.

The rule is intended to reduce emissions of toxic air pollutants such as formaldehyde, acetaldehyde, acrolein, methanol and other air toxins from several categories of previously unregulated stationary engines.

Engines Affected By EPA's NESHAP Ruling

The rule is applicable to the following types of natural gas engines:

• Current spark ignited engines in use (not new)
• 4 Stroke Lean Burn (SLB) engines
• 4 Stroke Rich Burn (SRB) engines
• Landfill or Digester Gas engines
• 2 Stroke Lean Burn (SLB) engines
• Emergency and non-emergency use natural gas fueled engines

Ruling Requirements

The affected stationary spark ignited engines must comply with emission limits or must be fitted with emission controls, such as oxidation catalysts, to reduce CO or formaldehyde emissions.

The rulings include a number of other provisions, including work practices, operating limitations, start up requirements and how to demonstrate compliance. While the regulation does not mandate the emission control technology, the EPA designed the standards based on the capabilities of oxidation catalysts.

How Can Universal Help?

1. Emissions components to meet regulations

   In order to make existing sources SI RICE NESHAP compliant, an oxidation catalyst is an appropriate emissions control device. Universal has the experience to guide you all the way to compliance, from sizing and design to unit installation and monitoring. Your site will be NESHAP compliant with equipment designed and installed per your specifications.

2. Testing and site evaluation

   Universal can help you evaluate your specific facility and emission sources. We have the capabilities to visit your site and gather the necessary data for SI RICE NESHAP compliance, including back pressure measurements, installation options, temperature and emissions requirements.

3. Monitoring and controls

   Universal provides a comprehensive data logging monitoring system that allows easy documentation of requirements for SI RICE NESHAP reporting, including catalyst inlet temperature and pressure drop across the catalyst.

4. Information and recommendations

   Our staff can offer technical guidance, interpretations of regulations, evaluation of engine performance and emissions output and help you decide what the right alternative is to make your site SI RICE NESHAP compliant.
