1997]

    Effective Date Note: At 71 FR 27332, May 10, 2006, Sec.  60.31b was 
amended by adding the definitions of ``EPA,'' ``Semi-suspension refuse-
derived fuel-fired combustor/wet refuse-derived fuel process 
conversion,'' and ``Spreader stoker fixed floor refuse-derived fuel-
fired combustor/100 percent coal capable'' in alphabetical order, 
effective July 10, 2006. For the convenience of the user, the added text 
is set forth as follows:

Sec.  60.31b  Definitions.

    EPA means the Administrator of the U.S. EPA or employee of the U.S. 
EPA who is delegated to perform the specified task.

                                * * * * *

    Semi-suspension refuse-derived fuel-fired combustor/wet refuse-
derived fuel process conversion means a combustion unit that was 
converted from a wet refuse-derived fuel process to a dry refuse-derived 
fuel process, and because of constraints in the design of the system, 
includes a low furnace height (less than 60 feet between the grate and 
the roof) and a high waste capacity-to-undergrate air zone ratio 
(greater than 300 tons of waste per day (tpd) fuel per each undergrate 
air zone).
    Spreader stoker fixed floor refuse-derived fuel-fired combustor/100 
percent coal capable means a spreader stoker type combustor with a fixed 
floor grate design that typically fires 100 percent refuse-derived fuel 
but is equipped to burn 100 percent coal instead of refuse-derived fuel 
to fulfill 100 percent steam or energy demand.
