9 1-Hour SO 2 NAAQS 75 ppb 3-year average of the 99th percentile of the annual distribution of daily maximum 1-hour concentrations. Existing guidelines for meteorological data still apply: 5 years NWS or 1 year onsite The 99 th percentile corresponds to the average of the 4th highest daily maximum. NWS: National Weather Service Copyright Lakes Environmental Software 1-9

10 1-Hour NO 2 NAAQS 100 ppb 3-year average of the 98th percentile of the annual distribution of daily max 1Hr concentrations. Existing guidelines for meteorological data still apply: 5 years NWS or 1 year onsite The 98 th percentile corresponds to the average of the 8th highest daily max 1-hr. NWS: National Weather Service Copyright Lakes Environmental Software 1-10

11 CALPOST Ranked Values Ranked Value corresponds to NAAQS percentile: SO 2 : 99 th and NO 2 : 98 th Daily Peak (6.292 only) produces daily maxima of 1- hour average Copyright Lakes Environmental Software 1-11

12 24-Hour PM2.5 NAAQS 35 µg/m 3 3-year average of the 98th percentile Existing guidelines for meteorological data still apply: 5 years NWS or 1 year onsite SIL: Highest of the 5-year averages (NWS) or 1 year (onsite) of maximum modeled PM 2.5 Copyright Lakes Environmental Software 1-12

13 Regulatory Guidance Draft Guidance for PM2.5 Permit Modeling Draft_Guidance_for_PM25_Permit_Modeling.pdf Defines recommended approaches for assessing Primary and Secondary PM2.5 impacts Copyright Lakes Environmental Software 1-13

14 Secondary PM 2.5 CALPUFF: 1. Produces sulfates and nitrates at PM 2.5 range 2. Cannot not form all the PM 2.5 species 3. ISORROPIA is for inorganic chemistry only 4. Is NOT a photochemical model Copyright Lakes Environmental Software 1-14

15 Question 2 Does the EPA-Approved CALPOST support 1-hour NO 2 / SO 2 NAAQS? 1) Yes 2) No 3) I don t know Copyright Lakes Environmental Software 1-15
