Appendix 1: Data Sources and Detailed Methodology by Emissions Source <br />Electricity <br />Electrical power within the boundaries of this inventory comes from two utilities, Eugene Water <br />and Electric Board (EWEB) and Blachly-Lane Electric Cooperative. The majority of the area is <br />served by EWEB, with the exception of a small wedge bisected by Hwy 99 south of Awbrey <br />Lane. This area is comprised primarily of commercial and industrial enterprises and is served by <br />Blachly-Lane Coop. <br />Data for total electrical load by sector were obtained for 1990 and 2005. EWEB provided <br />residential, commercial, industrial and water utility data. Blachly-Lane provided commercial <br />and industrial data. Blachly-Lane has no significant residential load within the boundaries of the <br />inventory. <br />Load growth projections were obtained from each utility to estimate the total use of each sector <br />in the target year. (Listed in summary of data inputs) <br />CO2 emissions coefficients for EWEB power for 1990, 2005 and projection for 2020 were <br />obtained from Jim Maloney, EWEB. CAP (criteria air pollutant) emissions coefficients were <br />calculated based on the CCAP software coefficients multiplied by percent of the resource in <br />EWEB’s mix and projected resource mix for each year. <br />It should be noted that most community wide inventories use emissions coefficients which are <br />standardized by NERC (North American Electricity Reliability Council) region. Because EWEB <br />power is significantly cleaner than either the US or regional average, custom emissions <br />coefficients were calculated and entered in the software. The table below compares the EWEB <br />coefficients to the regional and national standards. <br />Comparison of Emissions Coefficients (in lbs/MWh) <br />Region Year CO2N2OCH4NoxSox CO VOCPM10 <br />EWEB Electricity 1990 71.2800.0000.0030.0730.155 0.004 0.0010.009 <br />EWEB Electricity 2005 96.6000.0000.0040.0950.175 0.009 0.0020.010 <br />EWEB Electricity-projected 2020 96.6000.0000.0040.0930.169 0.010 0.0020.010 <br />NW Grid-WSCC/NWP 1990 969.4580.0780.0591.7741.640 0.575 0.0660.544 <br />NW Grid-WSCC/NWP 2005 1035.5730.0750.0581.3471.353 0.599 0.0670.521 <br />NW Grid-WSCC/NWP--proj 2020 967.4640.0620.0551.0781.019 0.661 0.0720.426 <br />USA total 1990 1478.6130.0210.0203.5858.194 0.216 0.0260.149 <br />USA total 2005 1491.5860.0210.0192.4615.486 0.218 0.0250.144 <br />USA total--projected 2020 1437.7200.0190.0192.0154.068 0.246 0.0270.126 <br />Sources for this information: <br />Joe McFadden, Manager Member Services, Blachly-Lane Electric <br />Tom Williams, Major Accounts, EWEB <br />Jim Maloney, Resource Project Manager, EWEB. <br />17 <br />
