When either EPA or EIA has more identifiers for the same units, this creates "duplicate" outputs in the crosswalk.

For example, the following two plants, included in the manual match file, with IDs 52151 and 7903 have duplicates for CAMD units and EIA units respectively.

CAMD_PLANT_ID CAMD_UNIT_ID CAMD_GENERATOR_ID EIA_PLANT_ID EIA_BOILER_ID EIA_GENERATOR_ID
52151 001 GEN1 52151 PB1 GEN1
52151 001 GEN1 52151 RF1 GEN1
52151 001 GEN2 52151 PB2 GEN2
