Excerpt: ... EPA does not provide objective rules on how to assign the J-rating. This inherently qualitative value has been assigned by the principal investigators of the profile ( Aerodyne Research, Inc. and EPA's Office of Research Development-National Risk Management Research Laboratory ) with input from the participants on this project. The speciation profile in Table 1 has been assigned a J-rating of " 5 " ( excellent ). Aircraft Speciated Hydrocarbon Emissions Inventories-Recommended Best Practice 8
