Gerd is quite right about the import process and list.  I would advise
joining the list and lurking for a month or two before posting, so that
you can calibrate yourself on the reactions.

Note that one thing you can do is to merge other data and OSM and then
run mkgmap on it.  I am 99% sure that if you do not distribute the
merged data, you will be ok with respect to OSM's ODbL.

Doing this has been on my todo list for a while, for both hydro and

This is inconsistent with the Contributor Terms.   So this data cannot
be added to OSM.

Again this is inconsistent.

This doesn't fit; OSM can attribute on wiki pages or changeset comments,
but cannot possibly demand (and does not, more importantly) that any map
have thousands of such disclaimers.

I would suggest talking to the NJDEP  and see if you can find a
sympathetic person, and if they would be willing to offer a license
compatible with the Contributor Terms.   You can point them at MassGIS,
which has terms that are basically Public Domain with attribution
requested.   But their terms are very far away from that, so I don't
expect rapid progress.

You might look at USGS data, and the National Hydrography Dataset,
which, being a work of the US government, is actually public domain.
