[Talk-us] Import of EPA data

I am generally in favor of imports.  But EPA superfund site data seems
to be getting close to "there should be mashup with this data and osm as
the baselayer" as opposed to importing it.

I'm on the light pollution committee in my town, and eventually I'd like
to have a database of issues.  I don't think this belongs in OSM, but as
a separate database that I'd use OSM as the baselayer for displaying.

The GNIS import has an accuracy problem, but most of those are easy to
fix because they are obvious places (church, school, etc.).  When you
examine a few of the EPA datapoints of which you have knowledge, how far
off are the markers from where they should be?  With pollution data in
particular, I'm nervous about putting points where they aren't.
