The little and not-so-little red dots on the map above show off sites on the EPA’s list of plants and refineries required to have a Risk Management Plan due to their potential for accidental hazardous chemical releases — with the larger dots showing the places that have already had an accident (or, in some cases, as many as 43).

The Union of Concerned Scientists and t.e.j.a.s. put together the interactive map as part of a report released late last week, which compares the EPA’s data on air quality and cancer rates in a few neighborhoods on the west side of town (specifically in Bellaire and in the West Oaks and Eldridge area, just inside Hwy.6 near the Barker reservoir) with the same data in a couple of east side spots (Galena Park and Manchester).
