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…

Who is responsible for controlling dust and debris from renovation waste once the waste container or truck used to transport the waste leaves the renovation site?
When a renovation firm transports waste from renovation activities, the firm must contain the waste to prevent release of dust and debris. The Lead Renovation, Repair and Painting (RRP) Rule does not address the responsibilities of other entities. EPA recommends consulting with state and local waste disposal authorities to learn…

For purposes of cleaning the work area following a renovation, is the interior floor of a garage considered interior or exterior space?
In general, the interior floor of a garage is considered an interior space for purposes of post-renovation cleanup. EPA recognizes the fact that it may occasionally be impossible for firms to meet all of the cleaning and verification requirements under the Rule for garage floors such as those that are…

If a renovator uses the required practices to remove containment and clean a work area, then performs successful cleaning verification, can the project then be done using uncertified workers and without work practices required by the RRP Rule?
Yes, as long as the balance of the project can be completed without disturbing a painted surface. Question Number: 23002-18385 Find a printable PDF copy of all frequent questions pertaining to lead .

My firm is replacing windows on a pre-1978 home. The homeowner already scraped and repainted their house but did not follow lead-safe work practices, leaving paint chips scattered throughout the landscaping. How best should I proceed?
A firm working on a property that is already contaminated with paint chips, dust, debris and residue must proceed by containing the work area for the renovation, and complying with all cleaning requirements under the Lead Renovation, Repair and Painting (RRP) Rule for that work area. Paint chips, dust, debris…

Under the RRP Rule, do paint chips and debris need to be removed from protective sheeting even if such chips and debris can be effectively contained by the sheeting or the sealed container the sheeting is contained in for disposal?
Yes. After the renovation has been completed, the firm must clean the work area until no dust, debris, or residue remains. The first cleaning step required by the Lead Renovation, Repair, and Painting (RRP) Rule is to collect all paint chips and debris and, without dispersing any of it, seal…

When waste from renovations has been removed from the work area and placed in on-site storage, may the waste be stored in a covered waste container or must it all be bagged for disposal?
Properly implemented, either option can meet the requirements of the Lead Renovation, Repair and Painting (RRP) Rule . At the conclusion of each work day and at the conclusion of the renovation, waste that has been collected from renovation activities must be stored under containment, in an enclosure, or behind…

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…

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…

Are components removed from the home to be cleaned up and reused subject to the waste handling requirements in the rule?
Answer : While components to be reused rather than disposed of are not considered waste for the purposes of the Lead Renovation, Repair, and Painting (RRP) Rule , it is likely that, even if they do not contain lead-based paint, they are contaminated with dust or debris from the project…
