What questions was EPA trying to find answers to during its first round of sampling at the Norwood Landfill site?
The main question that EPA seeks to answer is whether the identified waste areas warrant consideration for placement of the Site on the National Priorities List (NPL) or Superfund List. In the first round of sampling, EPA collected surface soil samples (0-2 feet) from the landfill property, and surface water…

What does it mean when EPA finds contamination that “exceeds screening levels?”
Screening levels are not the same as cleanup or action levels. An exceedance of a screening level indicates the need for additional evaluation, potentially including a site-specific risk assessment.

If EPA finds any contamination associated with the Norwood Landfill site that “exceeds” what is considered safe, will EPA clean up that contamination - even if the Agency cannot find any “pathways” for that contamination to reach humans or sensitive environments?
If the sampling data shows an exceedance of a screening level, EPA will consult with the site Toxicologist and the Agency for Toxic Substances and Disease Registry (ATSDR) to conduct a human health risk screening assessment to determine any potential threat to human health. EPA will also consult with the…

How do you know you are not missing some areas that might be contaminated?
EPA uses all credible information available, including community input, regarding the boundaries and geographic areas of waste that may have been deposited or where contaminated soil may have been placed. The team selects its sampling locations based on those areas and consults historic aerial images that help depict those boundaries.

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 EPA planning on taking samples from the basements in the homes you are sampling in the Norwood community? If not, why not?
EPA is not planning to collect samples from residential basements or crawl spaces at this time. EPA installed six groundwater wells within the Old Norwood Dump, Norwood Lower Park, and the Winona Homes neighborhood. Groundwater wells will not be placed on private residential properties. The wells will be used to…

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…
