2 UC Davis Air Quality Program Campus Air Permitting Program What sources need a permit? Regulatory review of proposed new sources Permit exemptions Permitting Process Naturally Occurring Asbestos

3 Yolo-Solano Air Quality Management District Air District Inspections Recordkeeping Requirements Permit Conditions and Limits Breakdowns Exceeded permitting thresholds/limits

4 Local, State, and Federal Air Quality Regulations Local Yolo-Solano AQMD Regulations State Regulations Air Toxics California Air Resources Board Federal Regulations EPA Tier diesel engine standards Title V Facility Permit

5 Local, State, and Federal Air Quality Regulations Local Yolo-Solano AQMD Regulations Forthcoming update to Boiler rule (lower NOx emissions requirements: Input size >1 and <5 MMBTU = 30 ppm NOx) State Regulations Air Toxic Control Measures (ATCM) CARB Certified Engines Federal Regulations EPA Tier diesel engine standards Title V Facility Permit

6 UC Davis Permits to Operate 95 Permitted Internal Combustion Engines 32 Permits for Boilers/Water Heaters 3 Permitted Fuel Dispensing Units Incinerator at Thurman Laboratory Landfill Gas Collection System and Flare

7 UC Davis Permits to Operate (Continued) Wastewater Treatment Plant 2 Cooling Tower Permits Paint-shop (Paint Booth) Dust Collector at Silo Craft Center Two Cyclones at Physical Plant

8 Permit to Operate Combustion: heat input >1 MMBtu/hour Internal Combustion Engines >50 BHP Gasoline Dispensing > 250 gallons Unit that emits >2 Lbs/day criteria pollutants (NOx, CO, SOx, VOC, PM10).Toxics

9 Permitting Exemptions Laboratory Equipment Chemical and Physical Analyses (bench scale tests - fume hoods) Combustion: heat input <1 MMBtu/hour Internal Combustion Engines: <50 BHP

10 Permit Exemptions (Continued) Electric Ceramic kilns, ovens, and/or furnaces Non-Commercial Food Processing (i.e. smoke house) Agricultural Exemption Laboratory Equipment fume hoods Vehicles Liquefied and/or compressed gases. Solvent dispensing containers (<100 gallons capacity)

11 Permitting Process Determine if a permit is necessary, Prepare permit application package, AQMD review and comment period, Authority to Construct (ATC), Installation/Construction (What is allowed?), Source testing (if required), AQMD Inspection & Permit to Operate (PTO)

12 Design and Construction Management (DCM) and EH&S roles DCM: During the project design/construction phase, please notify EH&S for unit specification review, regulatory review and location recommendations. Follow DCM Air Permitting Standard Operating Procedures EH&S: Perform regulatory review of specifications Prepare permit application package Submit permit application package to the AQMD Work with the AQMD to answer any questions they may have.

13 Equipment Selection Satisfy existing and forthcoming regulations. Internal Combustion Engines (Emergency Generators) Air Toxic Control Measure for particulate matter CARB Certified Engines EPA Tier diesel engine standards Add-on Controls (particulate trap, catalytic converters, etc.) Boilers/water heaters Low NOx burners Proposed boiler rule >1 and <5 MMBTU = 30 ppm NOx)

14 Permitting Pitfalls Permit application information must match up exactly to the equipment s nameplate (i.e. BHP, BTUs, model numbers, etc.). Air Toxic Control Measure (ATCM) for particulate matter in diesel engines. Avoid add-on controls and source testing. Timeframe to obtain ATC Equipment cannot be constructed/installed until ATC is issued.

15 Emission Reduction Credits (ERCs) What are ERCs? Cost to Purchase from Campus bank NOx=$15,000 per ton CO=$2,000 per ton VOC=$12,000 per ton SOx=$4,000 per ton PM10=$15,000 per ton

16 Asbestos ATCM for Construction, Grading, Quarrying and Surface Mining Operations 17 CCR State Asbestos Air Toxic Control Measure (adopted July, 2001). Trigger: large earthmoving activities in known Naturally Occurring Asbestos (NOA) soils, greater than 1 acre in size, require the preparation and implementation of an asbestos dust mitigation plan.

17 Asbestos ATCM for Construction, Grading, Quarrying and Surface Mining Operations Campus soils are considered low risk for NOA; however, the campus is located in an area that has been historically influenced by deposition of alluvial materials containing concentrated veins of naturally occurring asbestos. Standard practice - perform soil sampling on campus prior to large earth moving activities (>1 acre in size) to ascertain if there is the potential for NOA material.
