SIP Modeling Inventories
• Based on CCOS episodes (year 2000)
• SIP Gridded Inventory Coordination Group provided a forum for discussing inventory issues as modeling inventories were reviewed.
• As updates and corrections were made for July/August 2000 episode, other episodes benefited.
Examples of Updates and Corrections• Corrected problem in processing that
dropped some point and area emissions• Added locations for facilities with missing
UTMs• Revised on-road motor vehicle and biogenics
using CALMET temperatures• Adjusted SAPRC output to separately list
MTBE, MBUT and ETOH• Included updates to point and area source
emissions
Documentation
• Documentation of Methods to Develop Modeling Inventories (draft distributed to SIP GICG)
• Emission Inventory Branch’s Website Accessing SIP Emissions Projections : http://www.arb.ca.gov/app/emsinv/ccos/index.php– Report generators– Documentation– Control Rule Reports
July 1999 Inventory
• Not a CCOS episode
• Limited day-specific data for point and area sources:– includes shipping
– July/August 2000 episode included day-specific data for 65 large point sources, ag burning and wildfires
• 1999 base year for emission inventory (consistent with other episodes)
Development of July 1999 Inventory
• Alpine Geophysics developed modeling inventories under contract with BAAQMD and ENVIRON
• ARB provided point and area source files for weekday and weekend day in July 1999
• Alpine Geophysics developed biogenic and on-road motor vehicle emissions estimates
