(a) The North American Industry Classification System (NAICS) has replaced
the Standard Industrial Classification (SIC) system.
(b) The 'Establishments' column includes those units which reported any of the five listed
cogeneration technologies in use anytime in 1998, plus those units where usage of those
cogeneration technologies was not ascertained.
(c) This count includes only those establishments that reported any of the five listed
cogeneration technologies in use anytime in 1998.
(d) This count includes only those establishments that reported this
cogeneration technology in use anytime in 1998.
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.
