3. RICE NESHAP Market Enacted May 2010 Compliance deadlines (possibly extended pending delayed publication of proposed rule change on May 19, 2012) CI May 3, 2013 SI October 19, 2013 Proposed rule change to potentially include increasing non-revenue generating demand response hours to 60 Hours annually The Reality- Many have already moved ahead with retro-fits The deadline is approaching Capacity will be an issue Installation will be a bottleneck
4. Hazardous Air Pollutants (Air Toxics) 187 Chemicals & Compounds EPA RICE NESHAP – Requirements for Major and Area Sources Rule Focus Reduce the amount of Hazardous Air Pollutants (HAPS) from existing reciprocating internal combustion engines (RICE) Stationary Compression ignition (CI), Spark Ignition (SI) and dual fuel engines Existing and new/rebuilt stationary engines built before 2006 Carbon Monoxide (CO) is used as a surrogate Source Classifications Major Source: 10 tons/year or more of any one HAP Or 25 tons/year or more of a combination of HAPS Area Source: Any site that is not a major source Full Compliance Timing: Compression Ignition (CI): May 3, 2013 Spark Ignition (SI): October 19, 2013 Dual Fuel engines follow the CI timing and rule
5. EPA NESHAP Summary – Compression Ignition (CI) Engines SUMMARY: For both sources a Diesel Oxidation Catalyst (DOC) will be the prime path to meet the 70% CO reduction requirement
6. EPA NESHAP Summary – Spark Ignition (SI) Engines
7. Air-Fuel Ratio Controller Products AFR 1-9 Simple controllers for field MEC-R for rich burn natural gas engines MEC-L for lean-burn natural gas engines MEC-R MEC-L
8. Catalyst Performance 3-Way Catalyst 750°F – 1250°F inlet temperatures required for NOx, CO and HC reductions 1350°F maximum outlet temperature Catalyst degradation occurs above this point NG Oxidation Catalyst 550°F – 1250°F inlet temperatures required for CO reductions HC reduction is completely temperature dependent The higher the exhaust temperature the better the reduction 1350°F maximum outlet temperature Catalyst degradation occurs
9. RICE NESHAP – Monitoring & Testing Requirements
10. Metal Catalyst Substrate Understanding the Future of element manufacturing means understanding exhaust flow. What is Laminar Flow? What is Turbulent Flow?
11. Product Offering – DOC (PM/HC/CO Control) Diesel Oxidation Catalyst – HC, CO, PM reduction Place in front of SCR when no DPF Features Up to 30% PM reduction Up to 90% HC and CO reduction Integrated and non-integrated Durable metal substrates Serviceable

Red: Active aftertreatment expected. 2011+ emergency engine Tier 2 requirements avoid aftertreatment. Test cycles: D2 5-mode for Power Gen; C1 8-mode for Industrial. Tier 4i & f Stationary Emission Regulations New Engines – EPA NSPS Tier 4…….
14. NSPS for Stationary Diesel Engines Distinction between “non-emergency” and “emergency” Emergency engines are used during a power outage or conditioned power events Emergency engines are limited to 100 hours per year for maintenance and testing / no limit on operation during actual outage Some state or local agencies will require fewer hours for maintenance and testing States have ability to allow additional operating hours and will likely require emissions control of some variation Emergency engines must labeled as such at the factory Non-Emergency is anything that doesn’t qualify as “Emergency” Demand response, storm avoidance, rental units, etc. would be classified as “Non-Emergency” EPA proposed rule change allowing 60 Hrs/Yr demand response
15. Compliant vs Certified Solution Much confusion in the market place has been generated by the common specification calling for a Tier 4 (Interim or Final) engines by end users or engineering houses. Major engine manufacturers do not have completed engine model line-up of certified equipment ready for Tier 4i. The EPA’s position is still “certified” for revenue generating applications, yet business will go on and the states will have to make determinations on compliant solutions. Some state non-attainment areas will require emission targets more stringent than Tier ratings and target specific exhaust aftertreatment solutions will need to be provided.

20. Injection Control Systems Open Loop Injection Controllers: Injection rate based on field programmed load vs. urea injection curve Requires a portable load bank for constructing curve Not able to compensate for changes in engine operation, catalyst degradation, and ambient conditions Less efficient with regard to reducing agent Closed Loop Injection Controllers: Injection rate based on actual exhaust gas NOx concentrations Not load dependant Able to compensate for changes in engine operation, catalyst degradation, and ambient conditions Conserves reactant by continuously optimizing reducing agent injection rate to minimize over injection resulting and eliminating excessive ammonia slip
21. Reducing Agents SCR Process requires injecting a Reducing Agent into the Exhaust The reducing agent provides a reaction partner for NOx to turn into Nitrogen (N2) and Water (H20) Aqueous Urea or Ammonia may be used Urea is safe to handle and transport, non-toxic Ammonia is less expensive, but requires special handling, safety considerations, and permits Urea breaks down in the Exhaust into Ammonia (NH3) and Caron Dioxide (CO2) Heat and Moisture in the exhaust cause Urea to break down NOx reactions occur with the Ammonia
