The largest releases and transfers <strong>of</strong> methanol are from the pulp and paper (57.7%), organic<br />

chemical (21.3%), and the polymer and man-made fibers industry (6.2%) which contribute<br />

85.2% <strong>of</strong> the total methanol releases and transfers. Ethylene glycol releases and<br />

transfers are mostly from the polymer and fiber industry (62.5%), the rubber and plastics<br />

(19.1%), and the organic chemical industry (15.9%). These three industries contribute<br />

97.5% <strong>of</strong> all releases and transfers <strong>of</strong> ethylene glycol from the reporting industries. Toluene<br />

and xylene are typical paint, ink, cleaning and process solvents. The largest source <strong>of</strong> these
