Shale play a worry for Bexar ozone
There are concerns that development of the Eagle Ford Shale could push the San Antonio area over the limit of federal standards for ozone levels, an expert told the members of the Eagle Ford Task Force.
San Antonio is currently the largest city in the United States in full compliance with all federal air quality standards, said Peter Bella, natural resources director at the Alamo Area Council of Governments, but the city is right on the edge of nonattainment.
A big unknown is how Eagle Ford Shale drilling will affect ozone levels in the San Antonio area. Federal standards look at a three-year average of ozone levels using area monitors set up by the Texas Commission on Environmental Quality.
We dont have the data we need, Bella said, but were working hard to get it. That will require looking at a range of equipment, from diesel trucks to pumps, compressors, rigs and pipelines, he said.
