NONPOINT Fairly good. Uses 2005 Hawaii specific activity data where 

available (i.e., data from Hawaii WWTPs, Hawaii landfill data,

Some mainly smaller sources are missing. Some 2005 NEI 

categories not included in AirSHED: Avgas storage, 

woodstoves, fireplaces, open burning, mining and quarrying, 

portable fuel containers. For HAPs: cremation, hospitals, 

dental alloy production, labs, fluorescent lamp breakage, 

swimming pools, concrete gypsum plaster products, metal 

production, natural gas production. 

Recommend use of AirSHED data with NEI data for 

missing categories. However, consider review of NEI 

data for appropriateness for Hawaii (need to determine if 

methodologies used are appropriate for Hawaii).

swimming pools. Consider revising to add missing categories. May be able to use some of 

EPA data, but need to determine if methodologies used are appropriate for Hawaii. Also, 

Hawaii in process of revising open burning rules (outer islands previously allowed backyard 

burning) to only allow limited cases (i.e., fire fighting exercises, etc.)

*In 2008, EPA reclassified

 Aircraft emissions from the NONROAD category to the POINT source category, and 

 CMV and locomotive emissions from the Non Road category into the Area source category. AirSHED currently houses these 

emissions in their original source categories.

 Fire and dust from the AREA category to the EVENT category.

Question: If contract pursued, can the contracted EI updates be provided to CAB in the EIS format such that we can import 

into our EI database system (AirSHED)?
