Air Emissions from SLAC OperationsAir Emissions from SLAC OperationsAir Emissions from SLAC OperationsAir Emissions from SLAC Operations
• ESH Manual Chapter 30: Air Quality– Exhibits for specific program elements– Templates for recordkeeping included
• SLAC has an “umbrella” air permit– Covers all onsite emissions from various
sources• Combustion• Chemical Treatment• Evaporation / Curing• Refrigeration / Insulation
Typical Emissions SourcesTypical Emissions SourcesTypical Emissions SourcesTypical Emissions Sources
• Combustion– Generators/ Heavy Equipment
• Chemical Treatment– Solvent cleaners, degreasers
• Evaporation / Curing– Paints, coating, epoxies,
adhesives, etc.
• Refrigeration / Insulation– Freon, Off gassing
