KEY:
– Represents an estimate equal to zero or less than
1 unit of measure.
S Estimate does not meet publication standards because of highly sampling
variability or poor response quality.
1 SCTG codes were selected based on estimated tons without regard to sampling variability.
NOTE: Percentages represent the proportion of hazardous materials to the two digit commodity total.
