What is Vermiculite?
Vermiculite is the mineralogical name given to hydrated laminar magnesium-aluminum-iron silicate that resembles mica in appearance. All vermiculite ores contain a range of other minerals that were formed along with the vermiculite in the rock. Vermiculite ores from some sources have been found to contain asbestos minerals but asbestos is…

Redoing calculations if RMP*Comp is updated
Will RMP*Comp be updated? If so, would I have to redo calculations I might already have made with an earlier version? No, you do not have to redo your work if you have already completed your consequence analyses. RMP*Comp is based on the EPA's Offsite Consequence Analysis Guidance (OCA Guidance)…

Different distances to toxic endpoints with different versions of RMP*Comp
I've noticed that for certain chemicals, RMP*Comp gives substantially different distances to the toxic endpoint than previous versions. Why? In the current version of RMP*Comp, we have incorporated new chemical-specific distance tables for ammonia, chlorine, and sulfur dioxide. The generic tables are still used for other chemicals (you can see…

Distance to endpoint calculations used by RMP*Comp
Does RMP*Comp perform some math or modelling in order to arrive at an endpoint distance, or is it simply interpolating from the tables in the EPA's Offsite Consequence Analysis Guidance (OCA Guidance)? RMP*Comp follows the procedures set out in the OCA Guidance . This means that for some scenarios, the…

What is the definition of “overburdened community” that is relevant for EPA Actions and Promising Practices?
EPA Actions and Promising Practices apply the description of overburdened communities articulated in EPA’s Plan EJ 2014. The term is used to describe the minority, low‐income, tribal and indigenous populations or communities in the United States that potentially experience disproportionate environmental harms and risks due to exposures or cumulative impacts…

Are permit applicants required to adopt the Promising Practices?
EPA is not requiring permit applicants to adopt the Promising Practices. Promising Practices are simply that: good ideas in the form of suggestions to permit applicants. Permit applicants may benefit from applying these Promising Practices. EPA hopes that when permit applicants practice early and meaningful dialogue with the community, they…

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…

Minimum and Maximum Distance to Endpoint
The Chemical Accident Prevention Provisions require the completion of a worst-case release scenario analysis (40 CFR §68.25). This analysis includes estimating the greatest distance to endpoint as defined by the parameters in §68.22. Is there a required minimum or maximum distance for the distance to endpoint in the worst case…

If a permit is prioritized for enhanced outreach, does this mean that EPA will require stricter emission or discharge limits, or deny a permit?
An EPA regional’ office’s decisions on whether to issue a permit and, if so, the conditions to impose within a permit are distinct from the EPA regional office’s decisions about the outreach EPA may perform during the permitting process. EPA’s decisions on whether to issue a permit and what permit…
