 (a) The Bureau of the Census classifies establishments using the North American

Industry Classification System (NAICS). 

 (b) The environmental resrictions related to air quality that limit the amount of 

the usable alternative fuel that could be used instead.

 (c) Long-term contracts are typically with a utility or third-party supplier 

such as an energy broker and requires the purchase of a fuel for an extended 

amount of time. 

 (d) The storage of usable alternative fuels is not available due to the potential

environmental impact of storage tanks.

 NF=No applicable RSE row/column factor.

 * Estimate less than 0.5.

 W=Withheld to avoid disclosing data for individual establishments.

 Q=Withheld because Relative Standard Error is greater than 50 percent.

 NA=Not available.

 Notes: To obtain the RSE percentage for any table cell, multiply the cell's

corresponding RSE column and RSE row factors. Totals may not equal sum of

components because of independent rounding. Establishment percents may not

equal 100 percent because of unknown and/or unreported fuel-switching guesstimate.
