February 26, 2013

Agenda •  History and Regulatory Amendments •  Applicability •  Exemp=ons •  Regulatory Requirements •  What does it mean? •  Compliance Impacts and Op=ons •  Case Study •  Next Steps

About BlueScape •  16 years experience, full service

environmental firm •  Permits, air modeling, compliance for many

industries – power genera=on, u=lity, refinery, oil & gas, manufacturing and data centers

•  Na=onal Experience •  Solve tough air quality compliance issues:

-‐ Determining rule applicability -‐ Assess how to reduce impacts, change status -‐ Develop monitoring, recordkeeping and repor=ng protocols -‐ Agency nego=a=ons

RICE NESHAP Introduc=on •  Na=onal Emission Standards for Hazardous Air Pollutants for Reciproca=ng Internal Combus=on Engines

•  Regula=on 40 CFR Part 63 Subpart ZZZZ •  Exis=ng CI RICE must be in compliance by May 3, 2013 –  Except emergency CI > 500 hp at major sources

•  Exis=ng SI RICE must be in compliance by October 19, 2013

Rule History •  2002 – EPA issued proposed rule, to reflect Maximum Achievable Control Technology (MACT)

•  2004 – Exis=ng, new and reconstructed sta=onary RICE > 500 hp @ major sources

•  2008 – New and reconstructed sta=onary RICE < 500 hp @ major sources and new sta=onary RICE @ area sources

•  2010 – Exis=ng sta=onary RICE < 500 hp, non-‐emergency CI > 500 hp @ major sources, exis=ng sta=onary RICE @ area sources

Regulatory Amendments •  Sta=onary SI Engines > 500 hp @ Area Source –  Cataly=c controls for engines located in populated areas

– Management prac=ces for engines located in remote areas

•  Alterna=ve compliance for formaldehyde emissions for exis=ng & new 4SRB non-‐emergency > 500 hp @ major source –  76% reduc=on of formaldehyde –  30% reduc=on of total hydrocarbon emissions

Regulatory Amendments •  Star=ng 2015, emergency engines ≥ 100 hp –  Emergency opera=on of more than 15 to 100 hours per year

•  Recordkeeping and repor=ng –  Emergency opera=on of less than 15 hours per year

•  No control requirements or numeric emission limits
