# Summary • Work Group Purpose and Objective • Work Group History • Sector Roundtable Discussions - Sectors 2 

### - Roundtable Participants - Topics - Background Information - Timeline 

### • Early Observations

# Work Group Purpose and Objectives Provide information and advice to EPA regarding opportunities and challenges for advancing sectorbased, multi-pollutant approaches to air pollution control in major U.S. industries. 3

# Work Group History • Work Group proposed and discussed at May 2010 CAAAC meeting • Work Group launched and members solicited at October 2010 CAAAC meeting 4 

### • Series of 4 conference calls held in November and December 2010 to discuss Work Group charter, roundtable approach, and sector background info • Work Group meeting on January 10 to inform roundtable planning: • Related policy developments: risk and technology reviews; energy efficiency & GHG

# Sector Roundtable Discussions • Conduct a series of 1 -day roundtable discussions focused on the following sectors: - Iron and steel - Oil and gas production - Chemical manufacturing 5 

### • Roundtables discussions will involve: - Work Group members - Other interested CAAAC members - Representatives from 2 companies in the sectorProducing Wells Gathering Lines

Compressor Stations Processing Plant 

# Oil & Gas Production Sector Transmission Lines Large V olume Customer Crude Oil to Refineries (not in this sector)

# Iron and Steel Sector Sector covers 3 main types of plants: • Integrated Iron and Steel Plants - 18 facilities – some with co-located EAF and coke plants 

### • Electric Arc Furnaces (EAF) - 95 facilities – from 1 to 4 EAF per facility (1 to 2 typical) 

### • Coke Oven Plants - Most have multiple coke oven batteries - 19 facilities - 8 “Captive” – co-located at a steel manufacturing facility - 11 “Merchant” – manufacture and sell coke to other facilities

# Roundtable Topics • Overarching questions include: - How might a sector-based, multi -pollutant strategy optimize the reduction of air pollution for the sector? - What might optimization look like when considered in terms of emissions reduction, risk and impacts reduction, environmental justice, cost reduction, certainty, and operational and compliance 8 justice, cost reduction, certainty, and operational and compliance flexibility? 

### • Topic areas include: - Coordination of stationary source air pollution control regulations - Advanced air pollution control technology - Integrating energy efficiency into air pollution control practices - Environmental and community considerations

# Roundtable Topics • Coordination of stationary source air pollution control regulations - How could air pollution regulation (NSPS, NESHAPS, NAAQS, NSR, etc.) be better coordinated in the industrial sector? - How could record keeping, monitoring and reporting requirements of 9 - How could record keeping, monitoring and reporting requirements of various regulations be harmonized in a sector approach? - What are the best ways to group emissions sources in the sector for the purpose of coordinated regulation and emissions control? - What are the benefits and disbenefits of increased regulatory coordination and/or a sector approach? - What are the regulatory and legal challenges to implementing alternative sector-based approaches?

# Roundtable Topics • Advanced air pollution control technology - Which advanced technologies (process and/or emissions control) will assist in controlling multiple types of air pollution for the sector? - What are the benefits and implications of adopting these technologies in the sector? 10 - What are the roles of emission monitoring technologies and policies in facilitating multi -pollutant sector approaches? - Are there steps that can be taken to support more rapid technology adoption and equipment replacement?

# Roundtable Topics • Integrating energy efficiency into air pollution control practices - What is the interaction between energy utilization and efficiency efforts and conventional air pollution control strategies? - Would different regulatory strategies help increase energy 11 - Would different regulatory strategies help increase energy efficiency or reduce fuel consumption and achieve greater emissions reductions?

# Roundtable Topics • Environmental and community considerations

- Will multi -pollutant, sector-based approaches result in an improved facility environmental performance? 12 - Will multi -pollutant, sector-based approaches advance the consideration and reduction of cumulative health risks?

- Which policies and regulations in particular have the best chance of producing additional “co-benefits”?

- Will these approaches advance environmental protection efforts of Tribal, local, and state governments? Are they implementable?

# Early Observations • Strong interest persists in multi-pollutant, sector approaches • Familiar questions have surfaced regarding new approaches to environmental policies: emissions, risk, disproportionate impacts, cost, flexibility, beyond compliance 13 

### • Sector-based, multi-pollutant approaches offer a fresh look at specific sectors • Changes in technology, understandings of risk, and regulatory development tools could improve environmental results with less resources

# Next Steps ↠ Develop agendas for Clean Air Roundtable discussions ↠ Conduct Roundtables in February- March 2011 ↠ Assess results and draft Work Group Report: April - May 2011 ↠ Report and discuss findings with Clean Air Act Advisory Committee: June 2011, 14
