Note: For the National Emission Inventory (NEI), U.S. EPA used the same emission factor for PM10 and PM2.5. To be consistent with ARB's speciation profiles, PM10 emission factors were adjusted to reflect the following size ratio: [PM2.5 EF] = [PM10 EF]*[PM2.5 size fraction]/[PM10 size fraction] = [PM10 EF]*[0.9001]/[0.935] = [Emission reductions] = [Total emissions w/o reg.] - [Total emissions after reg.] [Total emissions after reg.] = [2009 emissions w/o reg.] + [Emissions from increased housing units after reg.]

Background: Feather River AQMD revised Rule 3.17 (W ood Heating Devices) on 10/5/2009.

Effective 10/5/2009, wood heating devices that are installed in new housing units

mu st be EPA-certified or meet other efficiency /operational standards. This spreadsheet was developed to estimate the emission reduction benefits from this rule and the associated "Control Profile" after rule implementation.
