1 Environmental Justice Enhancement I-4: Sample Projects South Coast Air Quality Management District

2 Introduction Example projects 1, 2 and 5 acre sites Existing building to be demolished –Assumed ½ size of site Commercial structure to be built –Assumed ½ size of site Assumed no operational impacts

3 Phases Demolition Clearing/grubbing Scraping/grading Trenching Building construction Architectural/asphalt paving/concrete paving Operation

4 Estimate Amount of Equipment Design plans Contractor estimates Similar projects Emission models (URBEMIS, EMFAC) Construction estimators (Richardson, RS Means, etc.) Manufacturer Information

5 Emission Estimation SCAQMD, EPA, CARB, OEHHA, CAPCOA methods and emission factors On-site and off-site sources Point source and fugitives Mobile and stationary sources

6 Site Preparation Phase Parameters VehiclesHours Rating (hp) Load (%) TripsLength Tractor/Loader/Backhoe Other Equip (Water Truck) Tractor/Loader/Backhoe Construction Worker Vehicles 520 Haul Trucks 820

7 Site Preparation Phase Emission Estimates COVOCNOxSOxPM10 Tractor/Loader/Backhoe Other Equip (Water Truck) Tractor/Loader/Backhoe Onsite (Haul Truck) Offsite (Construction Worker) Offsite (Haul Truck) Total Onsite Emissions Localized Significance Threshold Exceed Significance? NON/ANON/ANO Total Project Emissions Regional Significance Threshold Exceed Significance? NO N/ANO

8 1 Acre On-Site Emissions All Phases COVOCNOxSOxPM10 Demolition Site Preparation Grading Building Arch Coating and Paving Localized Significance Threshold Exceed Significance? NON/ANON/ANO

9 Conclusion Work in progress Input on methodology and additional examples from lead agencies and project proponents To be used in conjunction with Handbook
