Initial Concepts for Proposed Regulation XXXV

1
Initial Concepts forProposed Regulation XXXV

• Working Group Meeting
• February 9, 2005

2
Background

• Diesel particulate identified as a Toxic Air
  Contaminant (TAC) since 1998
• Long-term exposure to diesel particulate poses
  highest cancer risk of any TAC evaluated by OEHHA
• ARB conducted JR Davis Rail Yard study in
  Roseville
• High cancer risks (500 in a million)
• Idling represented 45 of diesel particulate
  emissions
• Locomotives are significant sources of criteria
  pollutants

3
Objective of Reg XXXV

• Monitor and record locomotive idling
• Reduce locomotive idling
• Conduct emissions inventory and health risk
  assessment at major rail yards in the Basin
• Reduce the cancer risk from diesel sources at
  major rail yards in the Basin

4
Proposed Rules

• PR 3500 - General
• PR 3501 - Recordkeeping For Locomotive Idling
• PR 3502 - Locomotive Idling Minimization
• PR 3503 - Diesel Risk Assessment For Rail Yards
• PR 3504 - Rail Yard Risk Reduction

5
Applicability

• Locomotives
• Class I freight railroads
• Switching and terminal freight railroads
• Operated in the Basin
• Four railroads meet applicability
• Railyards
• Major rail yards in the Basin
• Operated by Class I and switching and terminal
  freight railroads
• 7 rail yards

6
PR 3500 - General

• Key definitions
• Rely on existing regulatory definitions to extent
  feasible

7
PR 3501 Recordkeeping

• Purpose
• Monitor and report locomotive idling
• Identify unnecessary idling
• Inform public of idling events
• Idling Monitoring and Recording Plan
• Submit Jan. 1, 2006
• Identify methods to monitor, record, and transmit
  idling data to the District
• Methods to calculate emissions

8
PR 3501 Recordkeeping (Continued)

• Recordkeeping and Reporting
• Effective July 1, 2006
• All locomotives idling more than 15 minutes
• Times and dates of idling events
• Reason for idling
• Explanation of any idling event mitigation that
  is preempted by federal law
• Estimated idling emissions

9
PR 3501 Recordkeeping (Continued)

• Reporting requirements
• Submit daily records to the District
• Quarterly and annual report
• Maintain records for 2 years
• Public Notification
• Conduct public notification every 6 months
• Exemption for locomotives with anti-idling
  devices that limit idling time below 15 minutes

10
PR 3502 Idling Minimization

• Purpose
• Minimize duration, frequency and exposure to
  diesel particulate from locomotive idling
  minimize criteria pollutant emissions
• Idling Minimization Plan
• Submit July 1, 2006
• Identify strategies for all locomotives to
• Reduce duration of idling to lt 15 minutes
• Reduce frequency of idling events, and
• Reduce exposure to idling events

11
PR 3502 Idling Minimization (Continued)

• Idling Minimization Plan (Continued)
• Schedule to implement strategies
• Provide expected emission reductions
• Explanation why specific idling event cannot be
  minimized due to preemption by federal law
• Annual progress reports on idling reduction

12
PR 3503 Risk Assessment

• Health Risk Assessment Plan
• Submit January 1, 2006
• Diesel particulate emissions inventory and Health
  Risk Assessment
• Applicability
• Rail yard
• Includes all onsite diesel equipment
• Yard hostlers, forklifts, trains, etc.

13
PR 3503 Risk Assessment(Continued)

• Updates
• Emission inventory annually
• Health Risk Assessment if emissions increase
• Public notification requirement
• Cancer risk gt10 in one million

14
PR 3504 Risk Reduction

• Submit Risk Reduction Plan
• Required if PR 3503 risk level gt 25 in one
  million
• Due within 180 days of an approved HRA
• Evaluation of risk reduction measures and
  implementation schedule
• Evaluation of residual risk after measure
  implementation
• Annual progress report

15
PR 3504 Risk Reduction(Continued)

• Community Air Emissions Action Plan
• Submit January 1, 2006
• Designation of Community Liaison
• Schedule for community briefings
• Protocol for complaint resolution
• Fence Line Monitoring
• Monitoring program to measure diesel particulate
  at fenceline
