Overview 

Purpose:

Sensitivity analysis on how scale accuracies affect the relative uncertainty of emission estimates in the electric power transmission and distribution use sector (Subpart DD of the MRR). The data used in this analysis is 2008 reported data frfour Partners of EPA's SF6 Emission Reduction Partnership for Electric Power Systems. The names of the individual Parwhose data were used have been disguised to protect proprietary information that was reported to EPA voluntarily per thPartnership's memorandum of understanding (MOU).
