Sheet 1: Readme&change log
Note: This calculator may not be used for State Implementation Plans (SIPs) and Conformity. Consult your EPA Regional Office or SIP and Conformity guidance documents.”This calculator was updated May 21 2008 to include an estimation tool for fireplaces that are being replaced
by gas firelogs. This fireplace calculator assumes that the emissions from the gas firelogs are zero.
The fireplace calculator is in the "FP Results table" worksheet. Directions on how to use are on that worksheet.

This calculator also estimates the amount of emissions avoided if a number of conventional woodstoves
are replaced by EPA-certified woodstoves. The calculator has a function where you can estimate
the number of conventional woodstoves that get converted to gas heating units.

This calculator accounts for the increased efficiency of the EPA certified woodstoves

This calculator was further updated on July 30 2008 to include HAPs.

Inputs to the calculations are documented.
All the inputs to the calculator can be changed to match other data, as needed.
Users of calculator do not have to use default inputs. If more reliable inputs are available, you can use them.

Full name of MARAMA report is "Task 6, Technical Memorandum 4 (Final Report), Control Analysis and Documentation
for Residential Wood Combustion in the MANE-VU Region" Prepared for MARAMA by OMNI Environmental Services, Inc, Dec 19, 2006.

EPA's AP42 located on the web at
http://www.epa.gov/ttn/chief/ap42/index.html

Houck email - Jim Houck main point in his email to EPA staff is that the AP42 factor for Phase 2 certified stoves is based on testing in the late 1980's
and all on the first of the phase 2 models. Present day phase 2 models have improved. Emissions have improved from 19.6 to 12 lb/ton.

Change log
May 20 2009
Emission factors for PM10 and PM2.5 for fireplaces was changed to 22.2 lb/ton. The old value was from AP42 and
is superceded by a report from Huntley and Houck entitled
Updated Emissions Data for Revision of AP-42 Section 1.9, Residential Fireplaces, Dec 18 2002

Beefed up some references

May 28 2009

Changed the reference for the certified woodstove PM emission factor and moved some
references to the README worksheet.

Sept 24 2009
Version 2 changes

Burn rates revised based on national average burn rates. Based on the U.S. Department of Agriculture (USDA) Forest Service documents from Midwest or Great Plainstate surveys
performed in the 1990s (publications available from http://www.ncrs.fs.fed.us/pubs/).
A summary of the survey results is available in a tab to this spreadsheet.

Oct 27 2009 changes - version 3

Added a wood density worksheet. These values are state averages of oven dried wood densities. Source of data in the tab
These densities are used in the calculation to convert cords of wood to tons of wood
Added a burnrate tab and added the 3 tables explaining basis for burnrates used in calculator
Removed the "main" heat and "aesthetic" heat distinction for fireplaces. Now just use one burnrate for fireplaces. Simplifies equation.
Rename calculator tabs to "fireplace calculator" and "woodstove calculator"
