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…

Under the Asbestos Hazard Emergency Response Act (AHERA), can a local education agency (LEA) hire one abatement firm both to conduct a response action and to carry out the transmission electron microscopy (TEM) clearance air monitoring on that project?
No. In Unit II.B.2 of Appendix A to 40 CFR part 763, subpart E it states that TEM “[s]ampling operations must be performed by qualified individuals completely independent of the abatement contractor to avoid possible conflict of interest.” Accordingly, the LEA would have to select another person or firm “completely…

Do the Asbestos Hazard Emergency Response Act (AHERA) requirements in 40 CFR part 763 mandating routine facility inspections and management plan development apply to for-profit private schools as they apply in public K-12 schools?
AHERA requirements for facility inspections and management plan development do not apply to for-profit private schools, but they do apply to non-profit private K-12 schools. This exemption for private for-profit schools was directly mandated in the enabling legislation (the AHERA statute). Other Frequent Questions about Asbestos Learn About Asbestos Asbestos…

If friable asbestos-containing material (ACM) is accidentally left behind after an abatement project had passed air clearance by transmission electron microscopy (TEM) analysis, do I need to re-test the air?
Yes. Both the visual inspection and the abatement were not properly completed under 40 CFR part 763.90(i)(1). The loose debris should be removed and the area thoroughly re-cleaned. Air monitoring should be repeated using TEM analysis for the functional space where the original abatement occurred. (40 CFR part 763.90(f) and…

Under the Asbestos Hazard Emergency Response Act (AHERA), what is meant by the phrase "at approximately the same time" in 40 CFR part 763.90(i)(6) as it relates to transmission electron microscopy (TEM) clearance?
The intent of 40 CFR part 763.90(i)(6) is to prevent a local education agency (LEA) from avoiding the TEM air clearance requirement by either artificially dividing up a larger project, or by removing asbestos-containing building material (ACBM) in stages over the course of a relatively short period of time in…
