Email Regarding Review of NQ documentsFrom: Kiefer, Robyn V CIV USARMY CENWK (US) To: Barker, Justin Subject: West Lake review of NQ documents Date: Monday, November 13, 2017 5:15:37 PM Attachments: TMP Results.xlsx
Justin:
I asked our Mechanical engineer to review the NQ Annual report and asked she address the two key questions you and I discussed via the phone. Following are key points from our mechanical engineer's review of the NQ Annual report.
1. There was significant frustration in reviewing the report that the reports are inconsistently presenting data. Data is either presented in a different format or from different locations. While all reports included the classic TMP temperature graphs, the three monthly reports from Oct through Dec 16 only include the four TMP-SMP1 through 4, which were installed with the heat extraction barrier. The study report, date Nov 15, included TMP from 40 different locations. This latest report for the one year mark includes a total of 57 TMP locations of which 17 are either new or newly reported. These 17 are stated to be located in the neck area or the north quarry. However, no map can be found.
2. Question: Is the heat extraction infrastructure that is in place let us know if the SSE is moving (temp probes located to tell if the heat is increasing in an area, any indication of rising heat in any areas)?.
Answer: Yes and no.
What is in place are TMP locations in an approximate line through the north quarry from a point slightly north and on the west side of the neck that is parallel to the east edge of the north quarry closet to the neck from the neck north. (These are the following TMP; 21-23,16, 25, 17, 27, 18, 28 and 29, list in increasing distance from the neck. This values are either stable or cooling.) There is a line of TMP located across the neck. (These are the following TMP; 2-4, including 3R and 4R, list from west to east. This values are stable.) There are the two new ones north of the HEB, TMP-SPM-3 and 4. (These are cooling.) There are the two new ones south of the HEB, TMP-SPM-1 and 2. (One is cooling, while the cooler one is warming. The average is lower.) There are a few located between the original wells and the new wells. (These are the following TMP; 11 and 14R, list in increasing distance from the neck. This values are either stable or cooling.) There are TMP scattered around the original piolet wells. (These are the following TMP; 19,20,10-9N, 10-5N, 10-5S, 10-9S, 5-9N, 5-5N, 5-5S, and 5-9S. This values are cooling.) And there are a few TMP extending into the south quarry. (These are the following TMP; 15, 7R, 8, 31 and 32, list in increasing distance from the neck. This values are cooling.)
The initial installation appeared to be rather scattered vs. uniform grids. We recognize that TMP locations can be based upon where there is access. However, there is the possibility that if there is an irregular spread of a heat front, it could sneak past the TMPs.
It is the reviewer's opinion that TMP should be both reported relative to the location, which this last report attempted to do, but more information is required. What is the relative position and distance from the heat extraction barrier for each TMP location? This information goes a long way in evaluating the performance of the system.
3. Question: Is the heat extraction system cooling the surrounding area? (YES) Can we state that the cooling loops are in place and can assist in cooling the area, so if there is evidence that heat is rising that the existing system will help slow any northward advancement of the SSE?
Answer: Most likely yes, but there are too many possible variables to give a definitive answer.
Please keep in mind the large mass of the waste we are attempting to cool. The changes plus or minus are subtle.
The heat extraction barrier included the addition of 4 new temperature monitoring wells; two just north of the new

heat extraction wells (HEW-1 thru 16) and two just south of the new wells and north of the original pilot project wells. During the course of the last year the two sets of temperatures north of the HEW-1 thru 16 are lower, dropping 10 to 20 degrees F. The two sets of temperatures just south of the HEW-1 thru 16 have mixed results, but in average are cooler or the same. For all four probes, the maximum temperature is at or below 200 F, when before one was over 200 F by as much as 10 degrees F. The fact that some temperatures are higher to the south of the HEW-1 thru 16 does not deter from the heat that has been extracted as the rise in temperature can be a function of the heat (energy) moving toward the system to be extracted and not necessarily the SSE spreading.
Please note that "The original model also predicted rising temperatures in the region between the southern line of Gas Interceptor well extractors (GIW) and the line of heat extractor well (HEW) units." This is the movement of energy toward the wells for removal discussed above.
Out of 14 TMP located south of the new HEB, one close to the barrier is warming and another located between the rows of the piolet wells is neutral. All others, 12 out of 14 are cooling at this time.
Out of the 20 TMP north of the new HEB with more than one data report, all but 2 or 3 are either stable or cooling. Two show slight signs of warming while a third appears to be equalizing its temperature along its length.
See the excel sheet attached with a summary of TMP reports. The temperatures noted are the maximum along a length of a TMP.
Keep in mind the report's claim that "The 220 degree F isotherm line has either been stationary or has retreated south in the vicinity of GIW-10 (See Appendix E)."
Only time will tell if this statement is correct: "For all dates the model depicts lowering temperatures within the vicinity of the HEW line and temperatures below 170 degrees F at all locations from 40 feet south of the HEB line northward. The model results also show the HEB line acts as a line with overlapping zones of influence, negating the need for any additional heat exchange devices between the current HEB units."
The analysis did claim the following:
1) The SSE or the heat generated from it is reducing on its own. 2) "In general the inflowing water to the exchange units was warmer than assumed, and varied hourly as opposed to monthly." 3) "...energy removed was approximately 70% of the actual measured amounts on the HEW..." 4) "increasing the heat conduction of the waste from 1.4 to 1.6 W/mK" to better simulate the measured conditions. (They tweaked the model to match measured results.) 5) Increasing "the heat capacity of the waste from 2.4 to 2.6 Mjoule/m3" to better simulate the measured conditions. (They tweaked the model to match measured results.) 6) They also tweaked some correction factors to better simulate the measured conditions. 7) Remodeling into September 2019 "predicted continuing reduced temperatures in vicinity of the HEW line and a reduction in the rate of energy extraction." 8) " the energy released via decomposition of the waste under normal conditions diminishes with time and becomes near zero when temperatures elevate above 167 °F, above this temperature the bacteria responsible for generating methane die." 9) Southern boundary conditions were based on " readings from TMP-8 and TMP-7R from earlier dates (prior to failure of the units)." Higher than implied by TMP-31 &32. 10) Model assumed a more constant average inlet temperature vs. the measured inlet temperatures that varied too much for the model. The model would crash. (They tweaked the model to match measured results.) 11) "... a slight increasing of the temperatures closer to the ground surface."
Let us know when you'd like to discuss. Note that we'll need some advance notice for any discussion due to our mechanical engineer's workload.
Thanks, Robyn
Hi Robyn,
I left you a voice message earlier today regarding a request to have your team review two North Quarry related documents that were recently provided by the Parties. The specific documents are:
