					             Distribution of GHG Allowances to Petroleum Products Manufacturing Sector
                       Energy Efficiency Based Allowance Distribution Methodology
                           Proposed by the Western States Petroleum Association
                                     ®
                Using Solomon EII (Energy Intensity Index®) metric as a basis for relative efficiency

  This methodology has been designed to distribute free allowances across the refining sector
  according to facility performance and available allowances based on the cap reduction.

  This methodolgy uses Solomon's EII metric as part of the distribution factor to allocate GHG
  allowances according to relative energy efficiency.

  An equation to calculate a distribution factor for each facility is used to provide a higher ratio of
  GHG allowances to more efficient facilities, and a lower ratio to less efficient facilities.
         • The adjustment factors in the equation can be set so that the calculation provides 100% free
           allowances to the most efficient facility in the sector. All other facilities receive less than
           100% based on their EII value.
         • The technique pivots around the "average EII", which is approximately the EII at the mid-point of
           the sector emissions on an EII rank order basis (EII for each facility weighted using emissions).

   A calculation is performed for each facility to determine its distribution factor:
          Distribution Factor: DFx = ((Avg / EIIx) + Adj) / (1 + Adj)
                  where:    Avg -- weighted average EII for the sector:
                                   Avg = sum(BEx) / sum(BEx/EIIx)
                            Adj -- adjustment factor to provide most efficient facility 100% free allowances:
                                    Adj = ((Avg/EIIbest) * FA - 1) / (1 - FA)
                            EIIx -- EII for each individual facility in sector (determined by Solomon)
                            BEx -- GHG Baseline Emissions for each facility
                            EIIbest -- EII of most efficient facility (lowest EII in sector)
                            FA -- Free Allocation to refining sector, as a fraction (e.g. 0.97 for 97%)

  Prior to the compliance year, the Baseline Allocation to be provided to each facility is calculated as follows:

            Baseline Allocationx = BAx = BEx * DFx * FA              (calculate for each facility in sector)


  After the compliance period, the actual emissions from each facility are used to determine its
  final allocation of free allowances:
               Terms:       BEx -- Baseline Emissions (from above)
                            BAx -- Baseline Allocation (from above)
                            %Freex -- DFx * FA (from above)
                            AEx -- Actual Emissions for each facility (reported under MRR)
                            AAx -- Actual Allocation for each facility - final for compliance year
               Actual Emissions vs. Baseline:              Actual Allocation Equations:
                         • If AEx < BAx                    AAx = AEx + 20% x (BAx – AEx)
                         • If BAx < AEx < BEx              AAx = BAx
                            • If BEx < AEx                 AAx = AEx * %Freex

       Method to Distribute GHG Allowances to Petroleum Products Manufacturing Sector
                 Energy Efficiency Based Allowance Distribution Methodology
                    Proposed by the Western States Petroleum Association

Instructions for using this calculation spreadsheet:

   Prior to the Compliance Year - Calculate the Baseline Allocation for Each Facility:
1) All required input data is highlighted in blue:
      + Name of each facility
      + Baseline Emissions for each facility - basis for free allocation assistance calculation
      + Energy Efficiency (Solomon EII®) value for each facility
      + Cap reduction relative to total Baseline Emissions
2) The facility with the lowest EII value must be at the top of the list
      + Facility with the lowest EII will receive 100% free allowances (yellow highlighted)
      + Remaining facilities can be listed in any order
      + If there fewer than 21 facilities, then input a 0 for emissions and non-zero for EII for extra lines
3)   Hit Enter key after entering last value
4)   Hit F9 to calculate (if automatic calculation turned off)
5)   Check convergence
      + The calculation converged properly when the following two values are 0:
          - Confirm most efficient facility receives 100%                       0.0000
          - Confirm free allocations equal total available                        0.0
          - If not converged, then hit F9 to calculate again
          - If calculation will not converge, then cap reduction may be out of range (too high)                             When the actual Solomon EII values and GHG emissions for each
