How do the different parts of particulate matter (PM) fit together?
The various parts of PM in the NEI are related as follows. PM10-FIL > PM25-FIL because PM10-FIL includes PM25-FIL PM25-PRI = PM25-FIL + PM-CON This equation only applies at the process level. Because some sources only can report PM2.5 (due to test method differences), this equation does not apply to…

How does PM2.5 relate to PM species such as EC, OC, SO4, NO3, PMFINE, and DIESEL-PM25?
Primary PM2.5 estimates are speciated into the five PM species in the NEI: elemental (black) carbon (EC), organic carbon (OC), nitrate (NO3), sulfate (SO4), and the remainder of PM25-PRI (PMFINE). Diesel engine PM25-PRI and PM10 emissions are also labeled as DIESEL-PM25 and DIESEL-PM10 for mobile source diesel engines. For all…

EPA Actions does not require EPA regional offices to prioritize the same types of permits and adopt the same outreach activities. Why doesn’t EPA require regional offices to always prioritize certain permits and always do certain outreach activities?
EPA Actions strikes an important balance between national consistency and regional flexibility. The Agency‐wide guidelines establish national consistency by providing EPA’s expectations for the regional implementation plans. At the same time, EPA recognizes that the regional offices need the flexibility to take actions suited to the types of permits and…

Does EPA Actions apply to permits that are jointly issued by EPA and a state, tribal, or local permitting authority with partially delegated permitting authority?
EPA regional offices will decide whether a permit that EPA jointly issues with a state, tribal, or local permitting authority should be considered for prioritization for enhanced outreach as described in EPA Actions on a case‐by‐case basis. EPA will take into account its role and authority in issuing the specific…

Why doesn’t EPA do enhanced outreach for every permit?
Robust public outreach and engagement can consume a substantial amount of resources from all stakeholders in a permitting process and would not be warranted for every permit action. EPA recognizes that its regional offices cannot enhance engagement for every EPA‐issued permit and that overburdened communities might be overwhelmed with process…

How will an EPA regional office determine whether a permitted activity may have significant public health or environmental impacts?
Permit applications provide information on the proposed project consistent with the requirements of particular statutes and regulations. EPA may also do its own assessment of the environmental and public health impacts of a proposed project, using modeling and monitoring data for example. Such information would inform an EPA regional office’s…

How will EPA Actions apply to EPA‐permitted activities that may impact multiple EPA regions?
A permitted activity could potentially impact an area that straddles two or more EPA regions. The EPA region where the permitted activity is located usually has the lead for issuing the permit. EPA regions with the lead for issuing the permit routinely engage other regions impacted by the permitted activity…
