Public Hearing Williams Central Compressor Station Montrose Susquehanna Aug 28 2012 (Q&A only)

This is the 08/28/2012 Public hearing for a compressor station that is claimed as dual use (one of it's potential functions is the start of the feed of the constitution pipeline).  The PA DEP representatives are on the left, the right is three representatives from Williams.  Farthest left is the DEP's Community Relations Coordinator.  

Take note how many times  formaldehyde  is not volunteered by either the DEP or the Company representative when talking about emissions.   Now formaldehyde  will breakdown within about two hours when released into the atmosphere, so to claim there is a air monitoring station something like 2 hours drive away rarely down wind (Wilkes-Barre, Pennsylvania), will never measure the local impact.  PA is far from complete when it comes to drilling, so expect more of the same in the future.  There are many other questions & issues, like lack of a long term impact study, lack of general testing, DEP response time to issues, availability of foam for fighting fires, extcetera.

Here is a map (not sure how recent) of the air monitoring stations in PA.

Many times compressor stations are expanded (extra engines added) with out public hearing.  Provided below is an example compressor station. Air permit places this compressor station at (typically a rolling limit) of 41 tons per year.

For the compressor station in West Windsor with the recent accident, DUNBAR COMPRESSOR STATION, 414 DUNBAR RD, WINDSOR, NY.  "Plant-wide actual emissions of all HAPs ( hazardous air pollutants ), combined,
shall not exceed 24.5 tons per 12 month rolling period."  That would include benzene,
ethylbenzene, toluene and xylene and formaldehyde.  They won't have to install emission controls voluntarily, rather, the will do it to keep under the tons limit "...  Read more " Permit ID: 7-0350-00106/00001 Permit Issued To:WILLIAMS FIELD SERVICES COMPANY LLC"

Correction on my statement in the video:  Benzene, Toluene, Diesel Fuel all have HIGH ( not low ) relative vapor pressures as compared to water (Diesel fuel might be close to water). If you check the gas stream  yearly, you'll probably miss a spike when these volatiles evaporate off.  It would be similar to spilling 90% alcohol on the ground and checking for alcohol vapor 6 months later.
