NR 400.02(123e) PM2.5 means particulate matter with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers as measured in the ambient air for measuring massconcentration of particulate matter.The difference is in the diameter size of particulate matter present in ambient air as PM10 corresponds to 10 micrometers and PM2.5 corresponds to 2.5 micrometers.2.When a source determines its potential to emit a contaminant, are restrictions on hours of operation considered a limitation on the capacity of the source to emit an air contaminate?NR 400.02(127) Any physical or operational limitation on the capacity of a source to emit an air contaminant, including air pollution control equipment and restrictions on hours of operation or on the type or amount of material combusted, stored or processed, shall be treated as part of its design if the limitation is enforceable by the administrator.3.What is a fugitive emission?NR 400.02(71) Fugitive emission means an emission from any emission point within a facility other than a flue or stack.NR 4014.In Wisconsin those sources that are listed in or near a nonattainment area that must comply with RACT emission limitations must meet the limitations specified in which chapters of the Wisconsin Administrative Code?

The different region includes Minnesota, Illinois, and Dubuque. NR 4057.No major stationary source or major modification in an attainment area may begin actual construction unless the requirements of 405.08 to 405.16 have been met. What are those requirements/titles of those chapters?405/08 Requirements for beginning construction in an attainment area which fall under requirements listed in 405.08 to 405.16:-Control technology reviewSource impact analysisAir quality modelsAir quality analysisSource informationAdditional impact analysesSources impacting federal Class I areas — additional requirementsPublic participation
