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…

Why are gloves, which are exposed to large amounts of lead dust, not required to be disposed of under the Lead Renovation, Repair and Painting (RRP) Rule?
The RRP Rule requires the renovation firm to use precautions to ensure that all personnel, tools, and other items are free of dust and debris before leaving the work area. Workers with contaminated clothing can take that contamination home to their own children, and taking contaminated equipment to another jobsite…

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…

How should lead-containing wastes from RRP renovations be handled and disposed?
While at the work site, wastes must be collected at the conclusion of each work day and at the conclusion of the renovation and stored under containment, in an enclosure, or behind a barrier that prevents release of dust and debris out of the work area and prevents access to…

Can non-certified workers transport debris off site under the RRP Rule if they have had documented on-the-job training in this activity by the certified renovator?
Answer: Yes. The RRP Rule requires the certified renovator to regularly direct the work being performed by other individuals to ensure that the work practices are being followed, including ensuring that dust or debris does not spread beyond the work site. The certified renovator is responsible for providing training to…

Local meteorological data for alternative release scenarios
For alternate release scenarios, RMP*Comp uses set values for meteorological conditions like humidity, wind speed, temperature, stability class, and so on. Is there a way to change those values? I want to use meteorology data from my own location. RMP*Comp indeed uses fixed values for certain atmospheric parameters, and does…

Different results using ALOHA and RMP*Comp
I tried running the same scenarios in ALOHA and in RMP*Comp. I got different answers. Why? The results you obtain using RMP*Comp may not closely match the results you obtain running the same release scenario in a more sophisticated air dispersion model such as ALOHA or DEGADIS. That's because of…
