    sum
    of the emissions during operation by the
    number of hours of operation, excluding any time
    during which the equipment is idle.
    For process weight rates listed in Table 2.3.1,
    straight line interpolation between two consecu-
    tive process weight rates shall be used to determine
    allowable average emission rates.
