Greenhouse Gas Emissions Estimation Methodologies for Biogenic Emissions from Selected Source Categories
DRAFT - Greenhouse Gas Emissions Estimation Methodologies for Biogenic Emissions from Selected Source Categories: Solid Waste Disposal Wastewater Treatment Ethanol Fermentation (pdf) . Submitted by RTI International to the Sector Policies and Programs Division, Measurement Policy Group, US EPA, EPA Contract No. EP-D-06-118.
April 27, 2011 - update:
"Greenhouse Gas Emissions Estimation Methodologies for Biogenic Emissions from Selected Source Categories: Solid Waste Disposal, Wastewater Treatment, Ethanol Fermentation” was posted in December 2010, in order to assist certain biogenic sources to determine applicability for the “Tailoring Rule” that took effect on January 1, 2011. Since then, a few stakeholders have provided EPA with comments on the document.
In addition, EPA has published Deferral for CO2 emissions from Bioenergy and Other Biogenic Sources under the Prevention of Significant Deterioration (PSD) and Title V Programs: Proposed Rule (pdf) (238 KB).
This action proposes to defer for a period of three years, the application of the Prevention of Significant Deterioration (PSD) and Title V permitting requirements to carbon dioxide (CO2) emissions from bioenergy and other biogenic stationary sources (biogenic CO2) which would include the source categories mentioned above.
Because the deferral rulemaking has not been finalized at this time, biogenic CO2 emissions must still be estimated and included in applicability determinations for the PSD and Title V programs. As a result, we have decided to formally seek public comments on this document from all stakeholders and are marking it “draft” while we consider any additional comments.
In the meantime, the procedures and calculations described in the draft document continue to be an available tool for sources and permitting authorities to use at their discretion when making case-by-case applicability determinations.
