What Is AB 32? What Is AB 32? What Is AB 32?

  • Assembly Bill 32 sets in statute 2020 GHG

emissions target to roll back to 1990 levels

  • ARB to monitor/regulate GHG sources

– GHG come from: 89% CO2 , 6% CH4 , 5% other

  • Air Resources Board lead, but:

– Cal/EPA and Climate Action Team continue coordinating statewide climate policy – Other agency authorities preserved

What Is the Scoping Plan? What Is the Scoping Plan? What Is the Scoping Plan?

  • Tell how CA meets GHG level by 2020
  • Provide vision for low carbon future 2050+

– Reduction goal of 80% below 1990 levels

  • Establish CA leadership on addressing

climate change

  • Maximize benefits to CA

– Criteria and toxic air pollutant co-benefits – Economic development (green technologies)

slide-12

How Will the Scoping Plan Be Developed? How Will the Scoping Plan Be Developed? How Will the Scoping Plan Be Developed?

  • Identify maximum technologically

feasible and cost-effective measures

  • Assess possible mechanisms to achieve

reductions

– Market-based, direct regs, incentives, etc.

  • Evaluate scenarios to meet 2020 limit
  • ARB is responsible for Scoping Plan

– ARB working closely with Cal/EPA & Climate Action Team Subgroups & workshops

Oil and Gas Systems in California Oil and Gas Systems in California

  • 50,000 oil and 1,500 gas wells, including off-shore

platforms

  • Most oil wells located in the south, while most gas

fields located in the north

  • 250 million barrels of crude oil and 325 billion

cubic feet of natural gas in 2005

  • Over 3,000 miles of pipelines used for crude oil

and 12,000 miles for natural gas

  • Provides more than 20,000 direct and about

75,000 indirect jobs (CIPA and WSPA)

GHG Emission Sources GHG Emission Sources

  • Combustion Emissions (mainly CO2

):

– Boilers – ICEs (pumps, compressors) – Steam generators – Dehydrators – Flaring

  • Fugitive Emissions (mainly CH4

):

– Leaks (valves, flanges, seals) – Venting (dehydrators, compressors)

slide-19

Current Requirements Current Requirements

  • District Rules

– Vary by district – Combustion and fugitive emissions – Criteria pollutants and toxics – Permit requirements

Two Proposed Measures Two Proposed Measures

  • ‘Reduced Venting/Leaks from Oil and Gas

Systems’

– Approved by the Board October 25, 2007 – Early action measure – Transmission and storage activities – Adopt by December 2010

  • Propose second measure

– AB 32 Scoping Plan development – Extraction and processing activities – Adopt in 2011

Potential Options to Reduce GHG Emissions Potential Options to Reduce GHG Emissions

  • Fugitive Emissions

– U.S. EPA Natural Gas STAR Program

Deploy cost-effective technologies

(e.g., replace high-bleed pneumatics with low-bleed pneumatics, replace glycol dehydrators with desiccant dehydrators)

Implement best management practices

(e.g., practice enhanced directed inspection and maintenance at various facilities)

slide-22
SLIDE 22

22

Potential Options to Reduce GHG Emissions Potential Options to Reduce GHG Emissions

  • Combustion Emissions

– Repair

Perform routine maintenance

– Retrofit

Add components to existing equipment

– Repower

Substitute parts without replacing the entire equipment

– Replace

Install new equipment or use new fuels
