Except as specified in this section, all terms used in this subpart have the same meaning given in the Clean Air Act and subpart A of this part.
Bulk NGLs for purposes of reporting under this subpart means mixtures of NGLs that are sold or delivered as undifferentiated product.
Natural Gas Liquids (NGLs) for the purposes of reporting under this subpart means hydrocarbons that are separated from natural gas as liquids through the process of absorption, condensation, adsorption, or other methods, and are sold or delivered as differentiated product. Generally, such liquids consist of ethane, propane, butanes, or pentanes plus. [75 FR 66478, Oct. 28, 2010, as amended at 78 FR 71974, Nov. 29, 2013] Sec.

fuel, the carbon share in Table MM-1 of this subpart represents only
the petroleum-based components.\2\ Products that are derived entirely from biomass should not be
reported, but products that were derived from both biomass and a
petroleum product (i.e., co-processed) should be reported as the
petroleum product that it most closely represents.\3\ The density and emission factors for components of LPG determined at
60 degrees Fahrenheit and saturation pressure (LPGs other than
ethylene).\4\ The density and emission factor for ethylene determined at 41
degrees Fahrenheit and saturation pressure. [74 FR 56374, Oct. 30, 2009, as amended at 78 FR 71975, Nov. 29, 2013]
