  1. Air Quality Aspects for Construction Projects Subcontractor On Boarding Series 05/2012

  2. Air 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

  3. Typical Emissions Sources • Combustion • Generators/ Heavy Equipment • Chemical Treatment • Solvent cleaners, degreasers • Evaporation / Curing • Paints, coating, epoxies, adhesives, etc. • Refrigeration / Insulation • Freon, Off gassing

  4. SLAC Air Quality Programs • Permitting of New Sources • Non-SLAC Portable Equipment • Demolition / Renovation • No-Idling Policy • Hazmat Purchasing • Recordkeeping & Submittals

  5. Non-SLAC Portable Equipment • Regulated under statewide program • Voluntary program • Focus on diesel engines >50 HP • Registered for 3 years • Operate equipment anywhere in CA • Provide copy of PERP registration to SLAC • Portable Equipment Registration Program (PERP)

  6. Demolition / Renovation • Notify the Bay Area Air Quality Management District (BAAQMD), if required • Notification fee paid by ESH • Include project start and end dates • Notice signed by person performing work • Mandatory waiting period • 10 working days

  7. Renovation: Removal of As-containing material (ACM) from a structural member Sheet rock, floor tiles Notify BAAQMD of all renovations exceeding thresholds with friable asbestos Demolition / Renovation Demolition: Removal of a load-bearing structural member • Buildings, usually • Notify BAAQMD of all demolitions -- with or without asbestos!

  8. No-Idling Policy Statewide law for commercial vehicles SLAC Policy: Turn engines off • Whenever vehicle is stopped for >60 seconds • Applies to all vehicles while onsite • Personal , commercial and industrial • Exemption for special circumstances • Emergency vehicles

  9. Hazmat Purchasing • Haas system provides ‘single portal’ • Paints, coatings, solvents, epoxies, adhesives Be aware of better alternatives • Environmentally Preferable Purchasing (EPP) • Volatile Organic Compounds (VOC) content • “Low VOC” – typically, <300 grams/liter • Ozone-Depleting Substances (ODSs) • Greenhouse gases (GHGs) • Allowances for mission-critical operations

  10. Recordkeeping and Submittals • Prior to start of work • Pre-Work Hazmat List, w/MSDSs • During project: monthly logs • Hazmat use • Fuel consumption • Operating hours for portable equipment • Upon completion of work • Chemical Use Report • Templates available on ESH website
