Proposed Boiler MACT rule definition of “Energy Assessment:”

X. Energy Assessment : i. Energy Assessment for facilities using 0.04 to 0.3 TBtu/year

– Includes activities undertaken to identify energy performance improvements in a system. This assessment shall co nsider a subset of the major components and functions of the energy supply and energy use system in the facility, including : 1. steam

– boiler combustion management

2. boiler thermal energy recovery

3. condensate recovery

4. insulation improvements

5. steam trap improvem ents
ii. Energy Assessment for facilities using 0.3 to 1 TBtu/year

– Includes activities undertaken to identify energy performance improvements in a system. This assessment shall consider the components and functions in Xi, in addition to a large subset, but not necessarily all, of the major components and functions of the energy supply and energy use system in the facility, including key portions of the total steam or process heating systems in the facility.

iii. Energy Assessment for facilities using greater than 1 TBtu/year

– Includes activities undertaken to identify energy performance improvements in a system. This assessment shall consider all of the major components and functions of the energy supply and energy use system in the plant, including using the pr ocesses identified in the ASME steam and process heating standards.
