PM2.5 definition

PM2.5 means particulate matter with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers as measured by a reference method based on 40 CFR Part 50 Appendix L and designated in accordance with 40 CFR Part 53 or by an equivalent method designated in accordance with 40 CFR Part 53.

PM2.5 means particulate matter with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers as measured by an EPA reference or equivalent method.

PM2.5 means particles with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers.

Examples of PM2.5 in a sentence

• Catalytic and hybrid wood stoves meeting current NSPS certification may be identified by performing an advanced search and selecting the appropriate subtype (catalytic stove or hybrid) from the U.S. EPA Certified Wood Stove Database.19 Non-catalytic stoves do not perform as well in IDC testing, but to provide households with some non-catalytic options, four stoves approved by the State of Alaska for installation in the Fairbanks PM2.5 Nonattainment Area, listed in Table 1, will be eligible for incentives.

• Deliverables to include: Initial Study, Notice of Exemption, Preliminary Environmental Studies form, traffic technical memo, air quality PM2.5 exemption confirmation, water quality technical memo, Natural Environmental Study (Minimal Impact), Archaeological Survey Report, Equipment Staging Technical Memo, Initial Site Assessment Visual Impact Assessment (Moderate Impact).
