What state or federal agencies are responsible for evaluating records from the PADOH cancer registry? Are all types of cancers considered in this evaluation [including rare and/or environmentally associated cancers]?
A few important items to note regarding the Pennsylvania Cancer Registry: PADOH’s Pennsylvania Cancer Registry is a statewide data system responsible for collecting information on all new cases of cancer diagnosed or treated in Pennsylvania. It is part of the National Program of Cancer Registries administered by the Centers for…

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 a Pennsylvania registry that tracks non-cancer diseases or immunological disorders?
PADOH and the U.S. Department of Health and Human Services do not have a registry for multiple sclerosis (MS), MS-related diseases or immunologic disorders. Despite extensive research on the mechanisms of MS development and progress, the exact mechanism is not known and there are no definitive studies to show causation…

Does an ethanol producer who sells undenatured ethanol to a U.S. importer who denatures it at the port need to register with EPA under RFS?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The RFS regulations specify that foreign producers of ethanol for use in transportation fuel, heating oil or jet fuel for import to the US who do not add denaturant to their product, must register under RFS. See 80.1450(b)…

How do we know our drinking water has not been affected over the past 40+ years when the landfill was operating and after it closed since there were no regulations governing its operation or closure?
The Norwood community is serviced by a public drinking water source. The public water supply must meet federal and state Safe Drinking Water Act Standards. Public water systems are required to share annual reports that describe what, if anything, is found in the water supply.

RMP*Comp and emergency response
Can I use RMP*Comp for emergency response? No. It's a planning tool. Many other tools are available for response, including ALOHA . You can learn more by reading CAMEO tools for RMP .

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…

What are the requirements for a foreign producer who wishes to generate RINs for the renewable fuel they produce?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Foreign producers who plan to generate RINs must register and conduct a third-party engineering review pursuant to section 80.1450. Additionally, such foreign producers must meet the requirements in section 80.1466 prior to generating any RINs for their fuel…

Why is it difficult to establish a link between cancers or other illnesses and environmental exposures?
The complex nature of cancer makes it inherently challenging to identify, interpret, and address cancer clusters. Cancer is a term describing different diseases that share a similar characteristic: uncontrollable cell growth and division. As a group, cancers are very common. Cancers are the second leading cause of death in the…

How do we know that we have not been exposed to contamination from the Landfill for the past 40+ years?
EPA works closely with its partner, the Agency for Toxic Substances and Disease Registry (ATSDR) in evaluating potential health exposures from waste sources. ATSDR has the ability to look at the cancer registry data to evaluate potential past exposures, while EPA’s role is to evaluate current and future exposure. ATSDR…

Can Norwood residents be exposed to contamination if we grow and eat our own vegetables from gardens in our yards?
To date, contamination has not been found on residential properties that would pose a risk. In addition, the concentrations of the contaminants found at the Norwood Site are often found in urban communities. Studies show that exposure to contaminants via vegetable gardens is negligible. With the exception of some root…

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…
