Role of the Department of Public Works
Public Works, Environmental Programs Division
• Advise Board of Supervisors on Waste Management Issues
• Implement Waste Reduction Programs
• Prepare Disposal Capacity Planning documents
• Assist with Permitting of Solid Waste Facilities

disposed of
• 22 million tons per year (equivalent to filling the Rose Bowl 88 times)
• 4,300 lbs per person
per year
• 13 million tons per year
• 2,600 lbs per person per year
• 9 million tons per year
• 1,700 lbs per person per year

Waste Management Paradigm
Public Works, Environmental Programs Division
• Describes how the County and Cities plan to manage the disposal of solid waste for 15-years.
• Establishes criteria for siting disposal facilities.
6Public Works, Environmental Programs Division
Long-Term StrategyCountywide Siting Element
• AB 939 requires each County to prepare a siting element.
7
Status-Quo Scenario
• No increases in diversion rate
• No increases in out-of-County capacity
• No conversion technology facilities (only waste-to-energy)

Public Works, Environmental Programs Division
Reliance on existing disposal capacity alone is insufficient to meet long-term needs.

Sustainable Strategy
• Increase diversion to 75%
• In-County landfill expansions
• Conversion technology is operational
• Waste-by-rail is operational

Long-Term StrategyConversion Technologies (CT)
Environmental• Reduce air
emissions• Divert from
Landfills• Increase recovery
of materials
Economic • Produce energy
and biofuels• Create green
collar jobs
Community• Reduce truck
traffic • Provide local
options for waste management
Public Works, Environmental Programs Division
10
Long-Term StrategyConversion Technologies (CT)
Assisted jurisdictions and private companies with project development.
Build coalition of cities and state agencies in support of CTs.
Sponsor CT legislation: SB 804 (D-Lara)

Closure of Puente Hills Landfill
Public Works, Environmental Programs Division
• Closure has been accounted for in long-term projections.
• Anticipate higher costs due to tighter disposal market.
• Waste-by-Rail System aids in providing long-term security.
12
Next StepsCountywide Siting Element
Tentative Milestones
• Disseminate CEQA document (2014)
• Adoption by cities, and County Board of Supervisors (2015)
• Approval by CalRecycle (2016)
