3 AERMOD Modeling of Diesel PM from Construction Projects for BAAQMD The 0.53 ug/m3 is an average air concentration for the 113 day construction period. To annualize the concentration, 0.53 ug/m3 is multiplied by 113days/365days to get the estimated annual average value of 0.16 ug/m3. Table 1. Selected Project Data Project Estimated Project Area ft 2 m 2 Modeled Project Period Days in Modeled Period Cumulative Emissions (lb) Parker Place 60, /15/ /5/ Table 2. AERMOD Modeling Results Project Range of 50 Highest 1-hr Average Concentrations (μg m -3 ) Range of 50 Highest 24-hr Average Concentrations (μg m -3 ) Range of 10 Highest Period Average Concentrations (μg m -3 ) Parker Place Modeling notes: Two area sources (one for Parker Place South and one for Parker Place North) modeled; urban source options invoked; hourly emission inputs used, assuming demolition phase only occurs on the Parker Place South lot; 1 km 1 km receptor grid network with 20 m spacing centered on total project area, plus receptor points (10 m spacing) along perimeter of 10 ft. fence line buffers around each area source; 1.8 m receptor height above ground; simple flat terrain; meteorology for 2000; 27.7 m base elevation for potential temperature profile.

5 Backup Generators Location Proximal to Parker Place Mixed Use Development for Purposes of Air Quality Review Parker Place project site Note: The UC Corp Yard generator is just over 200 from the project site. The CoB Fire Station generator is located approximately 195 from the project site. Both generators are additionally separated from the project site by at least two structures that 12 tall or higher. Prevailing winds blow east, the sites are on the same north/south axis. UC CorpYard Generator CoB Fire Station Generator

After importing from URBEMIS, CO2 emissions are converted to metric tons and then adjusted to account for the "Pavley" regulation. Then, CO2 is converted to CO2e by multiplying by 100/95 to account for the contribution of other GHGs (CH4, N2O, and HFCs [from leaking air conditioners]). Finally, CO2e is adjusted to account for th low carbon fuels rule.

9 PRELIMINARY DRAFT SCREENING Bay Area Air Quality Management District Risk & Hazard Stationary Source Inquiry Form This form is required when users request stationary source data from BAAQMD. This form is to be used with the BAAQMD's Google Earth stationary source screening tables. For guidance on conducting a risk & hazard screening, including for roadways & freeways, refer to the District's Risk & Hazard Analysis flow chart. Also see the District's Recommended Methods for Screening and Modeling Local Risks and Hazards document. Table A: Requestor Contact Information For Air District assistance, the following steps must be completed: Map A: Snapshot of Google Earth with Plant Information Table Selected Map B: Snapshot of Google Earth with Plant G8736 Information Table Contact Name: Affiliation: Phone: 1. Complete all the contact and project information requested in Table A. Incomplete forms will not be processed. Please include a project site map. 2.

These values cannot be further adjusted using our screening tools, such as the diesel multiplier sheet. These values are based on modeling. If the Information Table says "Contact District Staff" include in Table B below. commercial, mixed use, 4. Using the Google Earth ruler function, measure the distance in feet between the project's fenceline and the stationary source's fenceline for all the industrial, etc.): sources that are within 1,000 feet of the project's fenceline. Verify that the location of the source on the map matches with the source's address in Project size (# of units, or building square feet): 155 housing units the Information Table, by using the Google Earth address search box to confirm that the source is within 1,000 feet of the project. Please report any mapping errors to the District (District contact information in Step 8). 5. If the stationary source is within 1,000 feet of the project's fenceline and the stationary source's information table does not list the cancer risk, hazard index, and PM2.5 concentration, and instead says to "Contact District Staff", list the stationary source information in Table B Section 1 Comments: below. 6. Note that a small percentage of the stationary sources have Health Risk Screening Assessment (HRSA) data INSTEAD of screening level data. These sources will be noted by an asterisk next to the Plant Name (Map B on right). If HRSA values are presented, these values have already been modeled and cannot be adjusted further. 7. this completed form to District staff (Step 8). District staff will provide the most recent risk, hazard, and PM2.5 data that are available for the source(s). If this information or data are not available, source emissions data will be provided. Staff will respond to inquiries within three weeks.

Site-specific information for screening details: Kohler Generator. John Deere engine, model #4045TF270. Year: Size: 62kw, average between 50 and 100hp. N/A distance to the nearest receptor: 330 feet. At this distance, the risk associated with the back up generator is estimated at 5.1 in a million. Natural gas boilers are less than 25 MM BTU/hr. See note 10b for more information on risk estimates. Emission Controls: None. Testing: 10 hours per year. 1. These Cancer Risk, Hazard Index, and PM2.5 columns represent the rows in the Google Earth Plant Information Table that say "Contact District Staff" (Map A above). BAAQMD will return this form to you with this screening level information entered in these columns. 2. Each plant may have multiple permits and sources. 3. Fuel codes: 98 = diesel, 189 = Natural Gas. 4. Permitted sources include diesel back-up generators, gas stations, dry cleaners, boilers, printers, auto spray booths, etc. 5. If a Health Risk Screening Assessment (HRSA) was completed for the source, the application number will be listed here. 6. The date that the HRSA was completed. 7. Engineer who completed the HRSA. For District purposes only. 8. All HRSA completed before 1/5/2010 need to be multiplied by an age sensitivity factor of The HRSA "Chronic Health" number represents the Hazard Index. 10. Further information about common sources: a. Sources that only include diesel internal combustion engines can be adjusted using the BAAQMD's Diesel Multiplier worksheet. b. The risk from natural gas boilers used for space heating when <25 MM BTU/hr would have an estimated cancer risk of one in a million or less, and a chronic hazard index of 3 or less. To be conservative, requestor should assume the cancer risk is 1 in a million and the hazard index is 3 for these sources. c. BAAQMD Reg 11 Rule 16 required that all co-residential (sharing a wall, floor, ceiling or is in the same building as a residential unit) dry cleaners cease use of perc on July 1, Therefore, there is no cancer risk, hazard or PM2.5 concentrations from co-residential dry cleaning businesses in the BAAQMD. d. Non co-residential dry cleaners must phase out use of perc by Jan. 1, Therefore, the risk from these dry cleaners does not need to be factored in over a 70-year period, but instead should reflect the number of years perc use will continue after the project's residents or other sensitive receptors (such as students, patients, etc) take occupancy. e. Gas stations can be adjusted using BAAQMD's Gas Station Distance Mulitplier worksheet. f. Unless otherwise noted, exempt sources are considered insignificant. See BAAQMD Reg 2 Rule 1 for a list of exempt sources. g. This spray booth is considered to be insignificant. UC Corporate Yard City Fire Station PRELIMINARY DRAFT SCREENING
