• 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…

• Is there any volume cap when using previously-retired 2008 or 2009 biodiesel RINs to satisfy an obligated party?s 2010 Biomass Based Diesel RVO? Can 2008 or 2009 biodiesel RINs that were previously-retired in 2009 also be used to satisfy Advanced Biofuel

  See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . 2008 and 2009 biodiesel and renewable diesel RINs (that is, RFS1 RINs with a D code of 2 and RR code of 15 or 17) used for compliance purposes in 2009 can also be used to reduce the…

• The regulations at 80.1427(a)(7)(iii) say that 2008 biodiesel RINS + 2009 biodiesel RINs cannot exceed 20% of the 2010 RVO. Does this mean that 80% of the 2010 biomass-based diesel RVO has to come from 2010 RINs?

  See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The 20% rollover cap under RFS2 is the same as the rollover cap under the RFS1 program. However, the rollover cap only places a limit on previous year RINs that were NOT used for compliance in 2008 or…

• 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…

• Under section 80.1405, the standard for biomass based diesel (BBD) is calculated via a fraction, the numerator of which is equal to the RFV for BBD in compliance year i times 1.5. For 2010 only, would you agree that, using the example of the calculation f

  See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The percentage standard for biomass-based diesel in years 2011 and beyond will be based upon the volumes specified in CAA 211(o)(2)(B)(i)(IV), unless some portion of that volume is waived per CAA 211(o)(7)(E). For 2010, the numerator of the…

• 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…
