The Wyoming
Department of Environmental Quality
announced on May 21 that it had to cancel
and reschedule its post-winter ozone season
meeting planned for that night in Boulder.
The DEQ has rescheduled the meeting
for Wednesday, June 26, from 6 to 8 p.m.
at the Boulder Community Center, 304
Adams St.
Bad roads and unsafe travel conditions
led DEQ Director Todd Parfitt to cancel
the May 21 meeting, which will have the
DEQ and its Air Quality Division address
the extremely high ozone concentrations
that occurred in March around the agency’s
Boulder South monitoring station.
Recently, Pinedale Anticline operators
addressed last winter’s ozone levels at their
annual planning meeting with the board
of directors at the Bureau of Land Management.
Each said they had worked with
DEQ and looked for possible emissions
leaks that might have contributed and found
nothing out of the ordinary.
DEQ officials have been asked if operations
with open condensation ponds at the
Anticline Disposal (now NGL Disposal)
could have led to extremely high one-hour
and eight-hour ozone levels, well over the
70 parts per billion federal standard. Some
of that information was expected to be
available at the May 21 meeting in Boulder.
