Dear Aaron:

We are beginning to receive some initial feedback from technical experts.  Below you will find comments from one of the gas experts.

These are more in the way of a 5,000 ft look down on the issues

1. The 2021 5 Year Review requested a comprehensive investigation of the LFG to define current conditions the source(s) and cause of the completely unexpected 2015 elevated LEL readings and determine what remedies continue to protect human health and the environment and which do not.  As part of the what was called a comprehensive LFG study, NMVOC testing was to be completed which would not only serve to assess current potential health risk but also the first and only comparison to date of the overall effectiveness of the "natural attenuation" plan.  The public does not have the results to attempt any credible and independent validation of what the 2026 Review concludes as "efforts were taken and all is good".   The 2026 report offers zero transparency. 
2. The 2026 Review states two public commentors submitted written responses to the 2026 Public Comment Period and both related to extension of the comment period when others, including Ohio Professional Engineers submitted written comments relative to the LFG, and specifically, the tatus of, and findings of the comprehensive study identified in the 2021 5 Year Review.   Why was the 2026 Review silent to public comments written and submitted to the USEPA within the initial timeframe? 
3. The 2026 Review suggests the overarching risk assessment used to define risk to the public may need to be updated due to emerging constituents and/or evolving baseline USEPA risk standards.  For a relatively small number of constituents of concern identified but not completed?  There is no timeframe to this, and like the LFG issue in general where unexpected spikes in reading in the 2015 timeframe are just now being discussed.  The timeframes being realized are unacceptable to the health and welfare of the public in proximity to this site  

Aaron, we thought that once the latest "Five Year Review" was completed, you would provide to us the data bases from which conclusions are being drawn!  This does not appear to be the case.  We once again request the following immediately be sent electronically to CCLT :

1)  All test results from all onsite and offsite gas/vapor testing conducted over the past five years.  This should include equipment used, ( stationery lab analysis, onsite equipment, their lowest detection limits and capablilities, limitations; all chemical parameters tested for, explosive and NON explosive .  Maps of locations of all sampling, and their depths..  All field notes indicating weather conditions, barometric pressures, seasons, temps. etc.

2)  All test results for groundwater from the past five years, as requested above, all parameters, detection limits, stationery lab, field notes, indicating methods used to collect samples, volumes of water collected, any filtration either in field OR at the lab.  A comprehensive list of all contaminants tested for and their lowest detection limits.  All depths and directions, seasonal variations, etc.

NO PUBLIC MEETING SHOULD BE CONVENED UNTIL  the above material has been provided and an experts and the public have had an adequate time to fully review the information.   There has been a serious lack of transparency on going at Uniontown IEL for several years, leaving the community in the dark.  We appreciate the quandary Region 5 is now in and are trying to "kick the can down the road" once again ( OR, should we say, kick the Army's canisters down the road?)....However, your agency's past "mistakes" does NOT justify withholding any further vital information potentially affecting the health safety and welfare of our citizens and beyond.
