EMERGENCY SLUDGE LOADOUT FACILITY (ESLF)
• The ESLF is used to load cake
solids when the furnaces are
out of service
• Sludge disposal sites are
needed
• Profile in place for potential
disposal at nearby landfill and
East Bay Municipal Utility
District (EBMUD)
• These two disposal sites are
not likely for long-term
disposal options, especially for
large volumes

ALTERNATIVES FOR SLUDGE DISPOSAL
• Past solids disposal has been very limited in volume
• Landfill will not be accepting municipal raw sludge in
response to SB 1383
• Central San staff is interested in finding alternate
disposal option that also results in safe and reliable
disposal methods and could be of beneficial use
