Subject:	Offsite Notice Clarifications

Based on questions on the offsite notice forms, the following clarifications are provided:

1.	Data is due to STB by 3/25/05
2.	The tables have columns labeled “Exceedances” with “(Yes or No)” underneath.  For the non-petroleum sites, you need only list the contaminants that had exceedances.  Do not list contaminants that were present but below their respective CTLs.
3.	For the groundwater tables and for contaminants that have a health-based level that is above the CTL based on organoleptic, nuisance, aesthetic conditions, list both the health based and organoleptic levels and indicate which are exceeded (which should be either both or just the organoleptic).  If there is only one or the other type of level, then leave the appropriate column blank.
4.	Use the most recent data you have available for any data point.  Do not list the whole history for each point.  This means that different data points on the same table may have different dates if they were not all sampled at the same time.
5.	For the two tables for sites with no data points (tables 2 & 4), report the data point that is closest to the offsite property, preferably upgradient of the off-site property for groundwater contamination.  For cases where there are intermittent properties with data (for example if you’ve hop scotched over more than one property), use the data point closest to both the property with no data and the property being investigated (i.e., upgradient from the property with no data points for ground water).  See the picture below for more explanation.  In this diagram (which was not drawn by a 5 year old, thank you very much), the data for property A would be reported as that from MW-1, while that from property C would be from MW-3.  Same rationale would apply to soil sampling.
6.	If the property boundaries are not clear from the site maps (or aerial photographs), then report each such point of unknown property location on a separate table as an unknown property location (use “Unknown” and a letter for property designation, e.g., “Unknown-A”, don’t re-use letters) but please make your best effort to identify property boundaries wherever possible.  STB will have to sort out the actual property boundaries.

Please do not hesitate to call if you have any questions, any questions at all, please don’t make up your own answers.  It certainly would have been nice to have more time to prep for this but we don’t, so we’ll need to work the kinks out as we go.  

Thanks,
Brian
