I am concerned however that Handley’s info the EPA has doesn’t match up with the company disclosed info below……..
Here is the company disclosed info on 2005, 2006 & 2007 emissions …
Here is 2007, 2008 & 2009….
And here is 2010, 2011 & 2012
But never fear Exelon is now entering into the renewables market…yeah…
Notice NO EMISSIONS TO REPORT ON THE WIND & SOLAR?
We need the mobile air monitoring van from Austin to measure formaldehyde downwind of these compressor stations during blowdown events. I bet (based on the Crosstex maintence schedule below) that the industry figures that each engine may need to be maintained once a week…..wow thats alot!
In the first pic of this blog of the compressor station (next to Exelon), my guess is that the BSEEC sponsored Titan air study ACCIDENTLY captured an unplanned blowdown (maintenance) emission event at the Lake Arlington Compressor Station a few years ago with high formaldehyde (127ppb) and carbonyl sulfide (130) readings.
The City of Ft Worth posted on their website a followup
on the one million dollar ERG air study. There was a problem with the estimated emissions on those (large line) compressor engines because ERG failed to figure in the emission control devices.
On the recheck on August 1 2011 for the Bailey/Boswell site, I was discouraged to find…..
1) Ref report#944873 they let them know in advance in July when they were coming.
When they got there, one compresser unit was OFF = strike #1
2) They (the FLIR camera) found a stuck open dump valve on a tank and TVA max recording was 100 ppm (not sure if taken after the fix) but a call into TCEQ with Robin who told me that the inspectors leave the machine on when they get there, so that the maximum reading (as it states is how she “infers” that this reading) was before the dump valve was closed.
When I tried to speak to Jessica Mock and Brian Yerkes…they both had moved on in their careers-
HOW CONVENIENT! = strike #2
3) no violations found = strike 3!
As for the Crosstex compressor station under a standard permit#75004, they reported 52 planned MSS blowdowns per engine (times about 12 engines?) HOLY HUNKSNOT!
This investigation was also “prescheduled”. During the inspection, TCEQ did not use (or report) TVA (toxic vapor analyser) readings, but did specify an areaRAE
machine reading which is not sensitive enough to read at parts per billion which is what our fire dept. uses. Our local and state governments need to start using a ppbRAE machine.
And for Railhead Barnett Gathering Compressor Station in Ft Worth, who is under an honor system PBR, also had forewarnings via a “scheduled” investigation passed their recheck too. Surely they would never plan a blowdown during one of these inspections!!!!!!!!!
It is worth noting that over the last year that 3 of our TCEQ Barnett Shale Investigators have moved on in their career..
Jessica Mock…..works at airport
Jessica Minley…works in gas drilling dept. for City of Arlington
Brian Yerkes…..works now for Quick Silver
At the RRC in our Kilgore Office, Mike O’Quinn went to work for the industry too.
update 9/9/13 I asked if any aldehydes were tested for in our drinking water and here is the repsonse….
The State monitors for Carbon Disulfide at the treatment plants on an annual basis. We do not test for aldehydes.
