NOTE Confidence: 0.891760738666667 00:00:07.830 --> 00:00:09.780 I want to acknowledge that NOTE Confidence: 0.891760738666667 00:00:09.780 --> 00:00:10.950 this presentation is, NOTE Confidence: 0.891760738666667 00:00:10.950 --> 00:00:13.566 is really focused on just one NOTE Confidence: 0.891760738666667 00:00:13.566 --> 00:00:16.046 aspect of sustainability and that's NOTE Confidence: 0.891760738666667 00:00:16.046 --> 00:00:18.020 the environmental footprint. NOTE Confidence: 0.913707824210526 00:00:20.690 --> 00:00:21.932 During this presentation, NOTE Confidence: 0.913707824210526 00:00:21.932 --> 00:00:24.416 we're going to start by looking NOTE Confidence: 0.913707824210526 00:00:24.416 --> 00:00:27.235 at the background of these open NOTE Confidence: 0.913707824210526 00:00:27.235 --> 00:00:29.103 source footprint analysis tools. NOTE Confidence: 0.913707824210526 00:00:29.110 --> 00:00:31.154 We're mainly going to be talking about NOTE Confidence: 0.913707824210526 00:00:31.154 --> 00:00:33.757 two of those tools that site wise and CPU. NOTE Confidence: 0.913707824210526 00:00:33.760 --> 00:00:35.279 So we're going to look at the NOTE Confidence: 0.913707824210526 00:00:35.279 --> 00:00:36.610 best uses of these tools. NOTE Confidence: 0.913707824210526 00:00:36.610 --> 00:00:39.808 Then we've got case studies and NOTE Confidence: 0.913707824210526 00:00:39.808 --> 00:00:41.940 of course key takeaways. NOTE Confidence: 0.913707824210526 00:00:41.940 --> 00:00:43.700 So, a brief history. NOTE Confidence: 0.771374 00:00:45.770 --> 00:00:49.364 In 2008, 2009, 2010, NOTE Confidence: 0.771374 00:00:49.364 --> 00:00:51.904 as Sustainable Remediation took off, NOTE Confidence: 0.771374 00:00:51.910 --> 00:00:54.355 the remediation community began developing NOTE Confidence: 0.771374 00:00:54.355 --> 00:00:58.026 new tools to assess the impact of NOTE Confidence: 0.771374 00:00:58.026 --> 00:01:00.886 remediation technologies on the environment. NOTE Confidence: 0.771374 00:01:00.890 --> 00:01:03.146 But the problem quickly became that NOTE Confidence: 0.771374 00:01:03.146 --> 00:01:05.070 everyone was using different tools, NOTE Confidence: 0.771374 00:01:05.070 --> 00:01:08.586 there was no consistency between assessments, NOTE Confidence: 0.771374 00:01:08.590 --> 00:01:11.243 and it became really difficult to consent NOTE Confidence: 0.771374 00:01:11.243 --> 00:01:14.137 to confirm that the correct or current NOTE Confidence: 0.771374 00:01:14.137 --> 00:01:16.242 emissions factors were being used. NOTE Confidence: 0.771374 00:01:16.250 --> 00:01:20.350 And that's where we began to see the rise of NOTE Confidence: 0.771374 00:01:20.450 --> 00:01:24.650 these public domain footprint analysis tools. NOTE Confidence: 0.771374 00:01:24.650 --> 00:01:27.030 Site Wise was released in NOTE Confidence: 0.771374 00:01:27.030 --> 00:01:29.665 2010 and the spreadsheets for NOTE Confidence: 0.771374 00:01:29.665 --> 00:01:31.246 Environmental footprint analysis, NOTE Confidence: 0.771374 00:01:31.250 --> 00:01:34.632 or CFA was released in 2012. NOTE Confidence: 0.771374 00:01:34.632 --> 00:01:38.426 Although each of these tools is different, NOTE Confidence: 0.771374 00:01:38.430 --> 00:01:41.566 they're really similar in a lot of ways. NOTE Confidence: 0.771374 00:01:41.570 --> 00:01:43.510 They're both excel based, NOTE Confidence: 0.771374 00:01:43.510 --> 00:01:45.450 they're both publicly available NOTE Confidence: 0.771374 00:01:45.450 --> 00:01:48.329 and they can both be consistently. NOTE Confidence: 0.771374 00:01:48.330 --> 00:01:51.700 Used to conduct footprint analysis. NOTE Confidence: 0.79687204 00:01:55.810 --> 00:01:57.885 Site Wise was developed jointly NOTE Confidence: 0.79687204 00:01:57.885 --> 00:02:00.771 by the US Navy, the US Army, NOTE Confidence: 0.79687204 00:02:00.771 --> 00:02:04.410 the US Army Corps of Engineers and BATTALE. NOTE Confidence: 0.79687204 00:02:04.410 --> 00:02:07.275 Sidewise was designed to calculate NOTE Confidence: 0.79687204 00:02:07.275 --> 00:02:09.567 the environmental footprint of NOTE Confidence: 0.79687204 00:02:09.567 --> 00:02:11.673 remedial alternatives that are NOTE Confidence: 0.79687204 00:02:11.673 --> 00:02:14.565 are commonly used by our industry. NOTE Confidence: 0.79687204 00:02:14.570 --> 00:02:16.620 The assessment is carried out NOTE Confidence: 0.79687204 00:02:16.620 --> 00:02:18.670 using a building block approach NOTE Confidence: 0.79687204 00:02:18.742 --> 00:02:20.542 where every remedial alternative NOTE Confidence: 0.79687204 00:02:20.542 --> 00:02:23.242 is first broken down into modules, NOTE Confidence: 0.79687204 00:02:23.250 --> 00:02:24.882 they're calculated individually NOTE Confidence: 0.79687204 00:02:24.882 --> 00:02:27.058 and then they're combined. NOTE Confidence: 0.79687204 00:02:27.060 --> 00:02:29.420 To create the full footprint NOTE Confidence: 0.79687204 00:02:29.420 --> 00:02:30.836 of the alternative. NOTE Confidence: 0.79687204 00:02:30.840 --> 00:02:33.008 And So what we're doing is we're inputting NOTE Confidence: 0.79687204 00:02:33.008 --> 00:02:35.498 all of this project specific information, NOTE Confidence: 0.79687204 00:02:35.500 --> 00:02:37.610 which in this case includes NOTE Confidence: 0.79687204 00:02:37.610 --> 00:02:38.454 material production, NOTE Confidence: 0.79687204 00:02:38.460 --> 00:02:40.590 transportation, equipment use, NOTE Confidence: 0.79687204 00:02:40.590 --> 00:02:44.140 residual handling and resource consumption. NOTE Confidence: 0.79687204 00:02:44.140 --> 00:02:46.932 We put all of that into the tool NOTE Confidence: 0.79687204 00:02:46.932 --> 00:02:49.422 and what the tool then outputs NOTE Confidence: 0.79687204 00:02:49.422 --> 00:02:52.356 is a detailed quantification of NOTE Confidence: 0.79687204 00:02:52.356 --> 00:02:54.840 these sustainability metrics, NOTE Confidence: 0.79687204 00:02:54.840 --> 00:02:57.164 which includes greenhouse gases. NOTE Confidence: 0.79687204 00:02:57.164 --> 00:03:00.502 Energy use, electricity use criteria, NOTE Confidence: 0.79687204 00:03:00.502 --> 00:03:03.358 air pollutants, water use, NOTE Confidence: 0.79687204 00:03:03.358 --> 00:03:06.878 resource consumption and accident risk. NOTE Confidence: 0.79687204 00:03:06.880 --> 00:03:10.132 Safewise was was really built to NOTE Confidence: 0.79687204 00:03:10.132 --> 00:03:11.758 compare remedial alternatives, NOTE Confidence: 0.79687204 00:03:11.760 --> 00:03:14.397 but it can be used to just look at NOTE Confidence: 0.79687204 00:03:14.397 --> 00:03:17.405 1 alternative or it can even be used NOTE Confidence: 0.79687204 00:03:17.405 --> 00:03:20.820 just on one component of 1 alternative. NOTE Confidence: 0.797578948333333 00:03:23.380 --> 00:03:26.187 Zifa was developed by the EPA and NOTE Confidence: 0.797578948333333 00:03:26.187 --> 00:03:29.040 it was first released in 2012. NOTE Confidence: 0.797578948333333 00:03:29.040 --> 00:03:32.696 This tool follows the EPA's methodology NOTE Confidence: 0.797578948333333 00:03:32.696 --> 00:03:35.836 for understanding and reducing a NOTE Confidence: 0.797578948333333 00:03:35.836 --> 00:03:37.720 projects environmental footprint. NOTE Confidence: 0.797578948333333 00:03:37.720 --> 00:03:39.208 Similar to site wise, NOTE Confidence: 0.797578948333333 00:03:39.208 --> 00:03:42.060 the Sifa tool follows a life cycle NOTE Confidence: 0.797578948333333 00:03:42.060 --> 00:03:44.775 approach when calculating the environmental NOTE Confidence: 0.797578948333333 00:03:44.775 --> 00:03:47.920 footprint of a remedial alternative. NOTE Confidence: 0.797578948333333 00:03:47.920 --> 00:03:51.126 So just like before, we're entering all NOTE Confidence: 0.797578948333333 00:03:51.126 --> 00:03:53.695 of these projects specific. Details. NOTE Confidence: 0.797578948333333 00:03:53.695 --> 00:03:56.005 It's formatted a little bit differently, NOTE Confidence: 0.797578948333333 00:03:56.010 --> 00:03:58.008 it's organized a little bit differently, NOTE Confidence: 0.797578948333333 00:03:58.010 --> 00:03:59.966 it's calculated a little bit differently, NOTE Confidence: 0.797578948333333 00:03:59.970 --> 00:04:03.288 but overall it's the same idea. NOTE Confidence: 0.797578948333333 00:04:03.290 --> 00:04:05.768 To me, there's really 2 main NOTE Confidence: 0.797578948333333 00:04:05.768 --> 00:04:07.420 differences between these tools. NOTE Confidence: 0.797578948333333 00:04:07.420 --> 00:04:10.101 The first is that SIPA is really NOTE Confidence: 0.797578948333333 00:04:10.101 --> 00:04:12.214 built to calculate the footprint NOTE Confidence: 0.797578948333333 00:04:12.214 --> 00:04:14.414 of of just one alternative, NOTE Confidence: 0.797578948333333 00:04:14.420 --> 00:04:17.356 but of course you can use that information NOTE Confidence: 0.797578948333333 00:04:17.356 --> 00:04:20.320 to to then do your own comparison. NOTE Confidence: 0.797578948333333 00:04:20.320 --> 00:04:22.240 But the second difference NOTE Confidence: 0.797578948333333 00:04:22.240 --> 00:04:24.160 are the output categories. NOTE Confidence: 0.797578948333333 00:04:24.160 --> 00:04:27.352 So CFA quantifies 21 metrics that NOTE Confidence: 0.797578948333333 00:04:27.352 --> 00:04:30.130 correspond to those five core NOTE Confidence: 0.797578948333333 00:04:30.130 --> 00:04:32.366 elements of an environmental NOTE Confidence: 0.797578948333333 00:04:32.366 --> 00:04:35.900 footprint as defined by the US EPA. NOTE Confidence: 0.797578948333333 00:04:35.900 --> 00:04:37.070 So we're looking at materials, NOTE Confidence: 0.797578948333333 00:04:37.070 --> 00:04:42.110 waste water, energy, air and land, NOTE Confidence: 0.797578948333333 00:04:42.110 --> 00:04:46.088 and ecosystem services. NOTE Confidence: 0.797578948333333 00:04:46.090 --> 00:04:48.932 But what's critical is that both of NOTE Confidence: 0.797578948333333 00:04:48.932 --> 00:04:51.459 these tools allow for flexibility, NOTE Confidence: 0.797578948333333 00:04:51.460 --> 00:04:55.515 and that includes user defined NOTE Confidence: 0.797578948333333 00:04:55.515 --> 00:04:57.137 emissions factors. NOTE Confidence: 0.797578948333333 00:04:57.140 --> 00:04:59.948 There's probably more reasons than just NOTE Confidence: 0.797578948333333 00:04:59.948 --> 00:05:03.775 these shown that you would want to use NOTE Confidence: 0.797578948333333 00:05:03.775 --> 00:05:06.115 these user defined emission factors, NOTE Confidence: 0.797578948333333 00:05:06.120 --> 00:05:08.920 but the two main ways that I've NOTE Confidence: 0.797578948333333 00:05:08.920 --> 00:05:10.400 run into is 1. NOTE Confidence: 0.797578948333333 00:05:10.400 --> 00:05:12.536 If you have a product with NOTE Confidence: 0.797578948333333 00:05:12.536 --> 00:05:13.960 a known emissions factor. NOTE Confidence: 0.797578948333333 00:05:13.960 --> 00:05:16.557 So say for example if you're using NOTE Confidence: 0.797578948333333 00:05:16.557 --> 00:05:18.203 Terra systems and multiplied NOTE Confidence: 0.797578948333333 00:05:18.203 --> 00:05:20.945 vegetable oil and you know that NOTE Confidence: 0.797578948333333 00:05:20.945 --> 00:05:22.960 it's certified carbon neutral, NOTE Confidence: 0.797578948333333 00:05:22.960 --> 00:05:24.685 maybe that's the reason you NOTE Confidence: 0.797578948333333 00:05:24.685 --> 00:05:27.050 chose it then you want to have. NOTE Confidence: 0.797578948333333 00:05:27.050 --> 00:05:28.277 Your your ego, NOTE Confidence: 0.797578948333333 00:05:28.277 --> 00:05:29.913 your emulsified vegetable oil NOTE Confidence: 0.797578948333333 00:05:29.913 --> 00:05:32.539 have a 0 carbon footprint, NOTE Confidence: 0.797578948333333 00:05:32.540 --> 00:05:37.310 but what the the tool has is a generic value. NOTE Confidence: 0.797578948333333 00:05:37.310 --> 00:05:40.014 So here you can see a generic impact NOTE Confidence: 0.797578948333333 00:05:40.014 --> 00:05:42.421 factor for just a just a typical NOTE Confidence: 0.797578948333333 00:05:42.421 --> 00:05:44.870 vegetable oil and so you could update NOTE Confidence: 0.797578948333333 00:05:44.870 --> 00:05:47.750 that value to zero in in this example NOTE Confidence: 0.797578948333333 00:05:47.750 --> 00:05:51.206 to have a more accurate result. NOTE Confidence: 0.797578948333333 00:05:51.210 --> 00:05:53.544 It's also important to think about NOTE Confidence: 0.797578948333333 00:05:53.544 --> 00:05:55.729 what these assumptions were based on. NOTE Confidence: 0.797578948333333 00:05:55.730 --> 00:05:59.069 So I know in particular for for site wise, NOTE Confidence: 0.797578948333333 00:05:59.070 --> 00:06:00.542 for the electricity use, NOTE Confidence: 0.797578948333333 00:06:00.542 --> 00:06:03.591 you select what state you're in and then NOTE Confidence: 0.797578948333333 00:06:03.591 --> 00:06:05.907 it pulls in an electricity assumption. NOTE Confidence: 0.797578948333333 00:06:05.910 --> 00:06:06.490 Of course, NOTE Confidence: 0.797578948333333 00:06:06.490 --> 00:06:08.230 if your site is located outside NOTE Confidence: 0.797578948333333 00:06:08.230 --> 00:06:09.250 the United States, NOTE Confidence: 0.797578948333333 00:06:09.250 --> 00:06:11.665 none of these would likely be appropriate NOTE Confidence: 0.797578948333333 00:06:11.665 --> 00:06:14.294 unless you were able to just go in and NOTE Confidence: 0.797578948333333 00:06:14.294 --> 00:06:16.348 choose the one that had the closest. NOTE Confidence: 0.797578948333333 00:06:16.350 --> 00:06:18.025 Instead of doing that instead NOTE Confidence: 0.797578948333333 00:06:18.025 --> 00:06:19.365 of having a proxy, NOTE Confidence: 0.797578948333333 00:06:19.370 --> 00:06:21.128 you could also get the assumption. NOTE Confidence: 0.797578948333333 00:06:21.130 --> 00:06:23.404 From your site or wherever you're NOTE Confidence: 0.797578948333333 00:06:23.404 --> 00:06:25.180 doing your assessment for an, NOTE Confidence: 0.797578948333333 00:06:25.180 --> 00:06:28.827 update that value for for the site NOTE Confidence: 0.797578948333333 00:06:28.827 --> 00:06:32.709 or for the updated assumption. NOTE Confidence: 0.797578948333333 00:06:32.710 --> 00:06:35.083 So we've been using these tools for NOTE Confidence: 0.797578948333333 00:06:35.083 --> 00:06:38.172 for a decade now and have come up with NOTE Confidence: 0.797578948333333 00:06:38.172 --> 00:06:40.621 the three things that we think are NOTE Confidence: 0.797578948333333 00:06:40.621 --> 00:06:43.050 the best uses for using these tools. NOTE Confidence: 0.797578948333333 00:06:43.050 --> 00:06:46.438 The first is using them to compare NOTE Confidence: 0.797578948333333 00:06:46.438 --> 00:06:47.890 the environmental footprint NOTE Confidence: 0.797578948333333 00:06:47.975 --> 00:06:49.928 of remedial alternatives. NOTE Confidence: 0.797578948333333 00:06:49.930 --> 00:06:52.570 You can see here in these graphs we're NOTE Confidence: 0.797578948333333 00:06:52.570 --> 00:06:54.830 comparing the generic alternative one, NOTE Confidence: 0.797578948333333 00:06:54.830 --> 00:06:58.450 alternative two and alternative three, NOTE Confidence: 0.797578948333333 00:06:58.450 --> 00:07:01.468 and this is often done during NOTE Confidence: 0.797578948333333 00:07:01.468 --> 00:07:02.977 the remedy selection. NOTE Confidence: 0.8872748 00:07:02.980 --> 00:07:06.280 Process. And if we done this assessment NOTE Confidence: 0.8872748 00:07:06.280 --> 00:07:07.978 and we have all of this data, NOTE Confidence: 0.8872748 00:07:07.980 --> 00:07:11.836 you may be wondering how do we incorporate NOTE Confidence: 0.8872748 00:07:11.836 --> 00:07:15.599 it into our decision making process? NOTE Confidence: 0.8872748 00:07:15.600 --> 00:07:17.960 Now I've seen sustainability added NOTE Confidence: 0.8872748 00:07:17.960 --> 00:07:20.837 as an additional criteria to whatever NOTE Confidence: 0.8872748 00:07:20.837 --> 00:07:23.047 the criteria that is typically NOTE Confidence: 0.8872748 00:07:23.047 --> 00:07:25.938 used or is required for a project. NOTE Confidence: 0.8872748 00:07:25.940 --> 00:07:29.052 But what we typically do is we incorporate NOTE Confidence: 0.8872748 00:07:29.052 --> 00:07:31.859 the results into the existing criteria. NOTE Confidence: 0.8872748 00:07:31.860 --> 00:07:33.675 We typically include our greenhouse NOTE Confidence: 0.8872748 00:07:33.675 --> 00:07:35.490 gas emissions into long term NOTE Confidence: 0.8872748 00:07:35.555 --> 00:07:37.700 effectiveness and permanence and we NOTE Confidence: 0.8872748 00:07:37.700 --> 00:07:39.416 include air pollutant emissions, NOTE Confidence: 0.8872748 00:07:39.420 --> 00:07:43.260 resource use, accident risk into our NOTE Confidence: 0.8872748 00:07:43.260 --> 00:07:45.820 short term effectiveness section. NOTE Confidence: 0.8872748 00:07:45.820 --> 00:07:48.388 We get a lot of information NOTE Confidence: 0.8872748 00:07:48.388 --> 00:07:50.100 from doing this analysis, NOTE Confidence: 0.8872748 00:07:50.100 --> 00:07:51.656 but you're probably wondering NOTE Confidence: 0.8872748 00:07:51.656 --> 00:07:53.990 how long it takes to complete. NOTE Confidence: 0.8872748 00:07:53.990 --> 00:07:56.279 We found that it takes about 10 NOTE Confidence: 0.8872748 00:07:56.279 --> 00:07:59.210 to 15 hours per alternative to NOTE Confidence: 0.8872748 00:07:59.210 --> 00:08:01.076 compare multiple alternatives. NOTE Confidence: 0.888528046428571 00:08:07.070 --> 00:08:11.494 But these tools aren't just giving us that NOTE Confidence: 0.888528046428571 00:08:11.494 --> 00:08:14.533 comparison information and we can also NOTE Confidence: 0.888528046428571 00:08:14.533 --> 00:08:17.293 look at just an individual alternative NOTE Confidence: 0.888528046428571 00:08:17.379 --> 00:08:20.187 and get a lot of value from that. NOTE Confidence: 0.888528046428571 00:08:20.190 --> 00:08:21.604 And that's what we're looking at here. NOTE Confidence: 0.888528046428571 00:08:21.610 --> 00:08:23.836 We're looking at just one alternative and NOTE Confidence: 0.888528046428571 00:08:23.836 --> 00:08:26.159 we're looking at just two of the metrics. NOTE Confidence: 0.888528046428571 00:08:26.160 --> 00:08:28.095 We're looking at greenhouse gas NOTE Confidence: 0.888528046428571 00:08:28.095 --> 00:08:30.030 emissions and total energy used. NOTE Confidence: 0.888528046428571 00:08:30.030 --> 00:08:31.880 And we've broken this alternative NOTE Confidence: 0.888528046428571 00:08:31.880 --> 00:08:34.370 into four phases of work and just. NOTE Confidence: 0.888528046428571 00:08:34.370 --> 00:08:36.210 With these two graphs, NOTE Confidence: 0.888528046428571 00:08:36.210 --> 00:08:38.510 it's visually pretty clear where NOTE Confidence: 0.888528046428571 00:08:38.510 --> 00:08:40.917 our impacts are coming from. NOTE Confidence: 0.888528046428571 00:08:40.920 --> 00:08:43.320 And with that information what we're NOTE Confidence: 0.888528046428571 00:08:43.320 --> 00:08:46.933 able to do is we're able to identify NOTE Confidence: 0.888528046428571 00:08:46.933 --> 00:08:49.819 our greatest areas of of opportunity. NOTE Confidence: 0.888528046428571 00:08:49.820 --> 00:08:51.871 We know our greatest footprint is then NOTE Confidence: 0.888528046428571 00:08:51.871 --> 00:08:54.309 we know where maybe we can implement a NOTE Confidence: 0.888528046428571 00:08:54.309 --> 00:08:56.430 best practice to reduce that footprint. NOTE Confidence: 0.888528046428571 00:08:56.430 --> 00:08:57.480 So we're looking at the graphs. NOTE Confidence: 0.888528046428571 00:08:57.480 --> 00:09:00.744 We see that darker blue color NOTE Confidence: 0.888528046428571 00:09:00.744 --> 00:09:02.920 consumables primarily in installation NOTE Confidence: 0.888528046428571 00:09:03.002 --> 00:09:05.600 of the cover and in replacement. NOTE Confidence: 0.888528046428571 00:09:05.600 --> 00:09:06.629 Of the revetment, NOTE Confidence: 0.888528046428571 00:09:06.629 --> 00:09:08.687 since we know that's where our NOTE Confidence: 0.888528046428571 00:09:08.687 --> 00:09:10.946 one of our larger footprints is, NOTE Confidence: 0.888528046428571 00:09:10.950 --> 00:09:13.910 maybe we want to consider identifying an on NOTE Confidence: 0.888528046428571 00:09:13.910 --> 00:09:16.887 site soil that can be used as a backfill. NOTE Confidence: 0.888528046428571 00:09:16.890 --> 00:09:19.866 Maybe we want to evaluate alternate NOTE Confidence: 0.888528046428571 00:09:19.866 --> 00:09:21.850 materials with lower footprints. NOTE Confidence: 0.888528046428571 00:09:21.850 --> 00:09:24.046 If we look at this turquoise NOTE Confidence: 0.888528046428571 00:09:24.046 --> 00:09:25.144 color residual handling, NOTE Confidence: 0.888528046428571 00:09:25.150 --> 00:09:28.048 maybe we would think about whether we NOTE Confidence: 0.888528046428571 00:09:28.048 --> 00:09:30.656 want some additional delineation so that NOTE Confidence: 0.888528046428571 00:09:30.656 --> 00:09:33.659 we're able to reduce our removal volume. NOTE Confidence: 0.888528046428571 00:09:33.660 --> 00:09:36.860 Maybe we can identify a NOTE Confidence: 0.888528046428571 00:09:36.860 --> 00:09:38.780 closer disposal facility. NOTE Confidence: 0.888528046428571 00:09:38.780 --> 00:09:41.836 Or if we look at the green bar, NOTE Confidence: 0.888528046428571 00:09:41.840 --> 00:09:44.988 we see transportation equipment. NOTE Confidence: 0.888528046428571 00:09:44.988 --> 00:09:48.923 Perhaps we would consider evaluating NOTE Confidence: 0.888528046428571 00:09:48.923 --> 00:09:51.029 transportation via via rail. NOTE Confidence: 0.888528046428571 00:09:51.030 --> 00:09:53.220 We have found that completing an NOTE Confidence: 0.888528046428571 00:09:53.220 --> 00:09:55.494 individual assessment takes a little bit NOTE Confidence: 0.888528046428571 00:09:55.494 --> 00:09:57.744 less time than a comparative assessment, NOTE Confidence: 0.888528046428571 00:09:57.750 --> 00:10:03.315 about 8 to 10 hours per alternative. NOTE Confidence: 0.888528046428571 00:10:03.320 --> 00:10:04.760 Last but certainly not least, NOTE Confidence: 0.888528046428571 00:10:04.760 --> 00:10:08.477 we're using these tools to calculate savings, NOTE Confidence: 0.888528046428571 00:10:08.480 --> 00:10:11.130 savings from optimization or savings NOTE Confidence: 0.888528046428571 00:10:11.130 --> 00:10:13.780 from implementation of one of NOTE Confidence: 0.888528046428571 00:10:13.867 --> 00:10:16.519 these sustainable best practices. NOTE Confidence: 0.888528046428571 00:10:16.520 --> 00:10:19.004 So if we take one of the best practices NOTE Confidence: 0.888528046428571 00:10:19.004 --> 00:10:21.359 that we identified on the last slide, NOTE Confidence: 0.888528046428571 00:10:21.360 --> 00:10:24.348 finding a local waste disposal facility NOTE Confidence: 0.888528046428571 00:10:24.348 --> 00:10:26.340 to minimize transportation impacts. NOTE Confidence: 0.888528046428571 00:10:26.340 --> 00:10:26.956 This is, NOTE Confidence: 0.888528046428571 00:10:26.956 --> 00:10:29.812 this is from one of my sites actually we NOTE Confidence: 0.888528046428571 00:10:29.812 --> 00:10:32.701 we were able to dispose of our aqueous waste. NOTE Confidence: 0.888528046428571 00:10:32.710 --> 00:10:35.524 In an on site groundwater treatment NOTE Confidence: 0.888528046428571 00:10:35.524 --> 00:10:39.060 plant versus at an off-site facility. NOTE Confidence: 0.888528046428571 00:10:39.060 --> 00:10:41.517 So there was no change to the NOTE Confidence: 0.888528046428571 00:10:41.517 --> 00:10:43.500 amount of IW generated. NOTE Confidence: 0.888528046428571 00:10:43.500 --> 00:10:45.240 There was no change in how NOTE Confidence: 0.888528046428571 00:10:45.240 --> 00:10:46.400 it was being treated. NOTE Confidence: 0.888528046428571 00:10:46.400 --> 00:10:50.208 But what we were able to do was NOTE Confidence: 0.888528046428571 00:10:50.208 --> 00:10:52.176 completely eliminate 26,000 Rd. NOTE Confidence: 0.888528046428571 00:10:52.176 --> 00:10:53.700 miles every year. NOTE Confidence: 0.888528046428571 00:10:53.700 --> 00:10:55.676 And we know that's going to reduce Rd. NOTE Confidence: 0.888528046428571 00:10:55.680 --> 00:10:56.028 congestion. NOTE Confidence: 0.888528046428571 00:10:56.028 --> 00:10:58.116 We know it's going to reduce NOTE Confidence: 0.888528046428571 00:10:58.116 --> 00:10:59.160 traffic through neighborhoods, NOTE Confidence: 0.888528046428571 00:10:59.160 --> 00:11:01.869 but we were also able to use site wise NOTE Confidence: 0.888528046428571 00:11:01.869 --> 00:11:04.197 to calculate our annual reduction NOTE Confidence: 0.888528046428571 00:11:04.197 --> 00:11:07.113 in greenhouse gas emissions and our NOTE Confidence: 0.888528046428571 00:11:07.187 --> 00:11:09.467 annual reduction in energy use. NOTE Confidence: 0.888528046428571 00:11:09.470 --> 00:11:12.025 Those are shown in green on this NOTE Confidence: 0.888528046428571 00:11:12.025 --> 00:11:14.380 slide and what's also shown in NOTE Confidence: 0.888528046428571 00:11:14.380 --> 00:11:16.340 black is our cost reduction. NOTE Confidence: 0.888528046428571 00:11:16.340 --> 00:11:18.776 So this wasn't calculated by site wise. NOTE Confidence: 0.888528046428571 00:11:18.780 --> 00:11:21.072 This was our actual cost reduction NOTE Confidence: 0.888528046428571 00:11:21.072 --> 00:11:24.164 and I wanted to include it because NOTE Confidence: 0.888528046428571 00:11:24.164 --> 00:11:27.140 there there continues to be this NOTE Confidence: 0.888528046428571 00:11:27.140 --> 00:11:28.726 misconception that sustainability NOTE Confidence: 0.888528046428571 00:11:28.726 --> 00:11:31.246 is somehow more expensive than NOTE Confidence: 0.888528046428571 00:11:31.246 --> 00:11:33.349 not taking into consideration NOTE Confidence: 0.888528046428571 00:11:33.349 --> 00:11:35.705 sustainability and that really NOTE Confidence: 0.888528046428571 00:11:35.705 --> 00:11:38.650 hasn't been what we've found NOTE Confidence: 0.861194716923077 00:11:38.737 --> 00:11:40.108 in my experience. NOTE Confidence: 0.861194716923077 00:11:40.110 --> 00:11:43.165 Reduction in the environmental footprint NOTE Confidence: 0.861194716923077 00:11:43.165 --> 00:11:48.290 has gone hand in hand with cost reduction. NOTE Confidence: 0.861194716923077 00:11:48.290 --> 00:11:50.210 This is a really fast process. NOTE Confidence: 0.861194716923077 00:11:50.210 --> 00:11:53.042 This typically takes about one hour NOTE Confidence: 0.861194716923077 00:11:53.042 --> 00:11:56.653 less than one hour per best practice NOTE Confidence: 0.861194716923077 00:11:56.653 --> 00:11:59.917 that that you're looking to calculate. NOTE Confidence: 0.861194716923077 00:11:59.920 --> 00:12:02.307 Which brings us to our case studies. NOTE Confidence: 0.861194716923077 00:12:02.310 --> 00:12:05.966 Again, we've got two case studies for today. NOTE Confidence: 0.861194716923077 00:12:05.970 --> 00:12:08.203 This first site is located on the NOTE Confidence: 0.861194716923077 00:12:08.203 --> 00:12:10.449 East Coast of the United States. NOTE Confidence: 0.861194716923077 00:12:10.450 --> 00:12:14.736 It was identified in 1998 as an NOTE Confidence: 0.861194716923077 00:12:14.736 --> 00:12:17.384 unauthorized debris disposal area. NOTE Confidence: 0.861194716923077 00:12:17.390 --> 00:12:19.478 So what you're looking at in this picture NOTE Confidence: 0.861194716923077 00:12:19.478 --> 00:12:21.387 is this is a really steep ravine. NOTE Confidence: 0.861194716923077 00:12:21.390 --> 00:12:23.546 And what runs at the top of NOTE Confidence: 0.861194716923077 00:12:23.546 --> 00:12:25.228 this steep ravine is a road. NOTE Confidence: 0.861194716923077 00:12:25.230 --> 00:12:26.670 It's this road that goes here, NOTE Confidence: 0.861194716923077 00:12:26.670 --> 00:12:30.358 and then it drops off really quickly here. NOTE Confidence: 0.861194716923077 00:12:30.360 --> 00:12:32.376 And what it appears to have NOTE Confidence: 0.861194716923077 00:12:32.376 --> 00:12:34.916 happened at This site is that trucks NOTE Confidence: 0.861194716923077 00:12:34.916 --> 00:12:37.160 driving along the road would stop, NOTE Confidence: 0.861194716923077 00:12:37.160 --> 00:12:40.008 they would back up and they would just NOTE Confidence: 0.861194716923077 00:12:40.008 --> 00:12:42.978 dump their contents down into the ravine. NOTE Confidence: 0.861194716923077 00:12:42.980 --> 00:12:44.524 And because of that, NOTE Confidence: 0.861194716923077 00:12:44.524 --> 00:12:46.454 there's buried and unburied debris. NOTE Confidence: 0.861194716923077 00:12:46.460 --> 00:12:47.980 There's wood, there's concrete, NOTE Confidence: 0.861194716923077 00:12:47.980 --> 00:12:48.740 there's metal. NOTE Confidence: 0.861194716923077 00:12:48.740 --> 00:12:50.948 And our investigations identified NOTE Confidence: 0.861194716923077 00:12:50.948 --> 00:12:54.260 potential risk from metals and soil, NOTE Confidence: 0.861194716923077 00:12:54.260 --> 00:12:57.338 as well as the potential for NOTE Confidence: 0.861194716923077 00:12:57.338 --> 00:13:00.114 continued leaching from the surface NOTE Confidence: 0.861194716923077 00:13:00.114 --> 00:13:02.610 and the subsurface debris. NOTE Confidence: 0.861194716923077 00:13:02.610 --> 00:13:04.938 And for this project, NOTE Confidence: 0.861194716923077 00:13:04.938 --> 00:13:07.848 we considered 3 remedial alternatives. NOTE Confidence: 0.861194716923077 00:13:07.850 --> 00:13:10.148 One was the no action alternative, NOTE Confidence: 0.861194716923077 00:13:10.150 --> 00:13:12.565 but the other two options were a NOTE Confidence: 0.861194716923077 00:13:12.565 --> 00:13:14.591 full removal and off-site disposal NOTE Confidence: 0.861194716923077 00:13:14.591 --> 00:13:17.339 and the installation of a low NOTE Confidence: 0.861194716923077 00:13:17.339 --> 00:13:18.750 permeability soil cover. NOTE Confidence: 0.861194716923077 00:13:18.750 --> 00:13:21.670 We did a full assessment for both of NOTE Confidence: 0.861194716923077 00:13:21.670 --> 00:13:23.963 these alternatives and here is the NOTE Confidence: 0.861194716923077 00:13:23.963 --> 00:13:26.195 relative impact table that was produced. NOTE Confidence: 0.861194716923077 00:13:26.200 --> 00:13:29.950 So this this table comes directly from NOTE Confidence: 0.861194716923077 00:13:29.950 --> 00:13:33.029 from the site wise tool in particular. NOTE Confidence: 0.861194716923077 00:13:33.030 --> 00:13:34.478 We didn't talk about it in the top, NOTE Confidence: 0.861194716923077 00:13:34.480 --> 00:13:36.797 but what it's showing is how the NOTE Confidence: 0.861194716923077 00:13:36.797 --> 00:13:38.670 footprint that has been calculated NOTE Confidence: 0.861194716923077 00:13:38.670 --> 00:13:40.685 for each of these alternatives NOTE Confidence: 0.861194716923077 00:13:40.685 --> 00:13:42.420 compares to the others. NOTE Confidence: 0.861194716923077 00:13:42.420 --> 00:13:43.540 So what it's saying is, NOTE Confidence: 0.861194716923077 00:13:43.540 --> 00:13:44.413 is for example, NOTE Confidence: 0.861194716923077 00:13:44.413 --> 00:13:46.159 in terms of greenhouse gas emissions, NOTE Confidence: 0.861194716923077 00:13:46.160 --> 00:13:48.172 alternative three is comparatively NOTE Confidence: 0.861194716923077 00:13:48.172 --> 00:13:50.687 high and also true alternative NOTE Confidence: 0.861194716923077 00:13:50.687 --> 00:13:52.798 two is comparatively low. NOTE Confidence: 0.861194716923077 00:13:52.800 --> 00:13:54.400 And so as you look across the table, NOTE Confidence: 0.861194716923077 00:13:54.400 --> 00:13:57.820 you can see alternative two is NOTE Confidence: 0.861194716923077 00:13:57.820 --> 00:14:00.950 comparatively lower to alternative 3IN all NOTE Confidence: 0.861194716923077 00:14:00.950 --> 00:14:03.500 categories except for water use where. NOTE Confidence: 0.861194716923077 00:14:03.500 --> 00:14:06.869 They're pretty similar. NOTE Confidence: 0.861194716923077 00:14:06.870 --> 00:14:09.302 And so we took that information and we NOTE Confidence: 0.861194716923077 00:14:09.302 --> 00:14:12.230 used it as an additional line of evidence. NOTE Confidence: 0.861194716923077 00:14:12.230 --> 00:14:14.490 It was considered alongside effectiveness, NOTE Confidence: 0.861194716923077 00:14:14.490 --> 00:14:18.250 alongside implementation and alongside cost. NOTE Confidence: 0.861194716923077 00:14:18.250 --> 00:14:20.446 And when we looked at all of them together, NOTE Confidence: 0.861194716923077 00:14:20.450 --> 00:14:22.680 it became really clear that NOTE Confidence: 0.861194716923077 00:14:22.680 --> 00:14:24.464 alternative two was the, NOTE Confidence: 0.861194716923077 00:14:24.470 --> 00:14:26.388 the option that we wanted to select. NOTE Confidence: 0.861194716923077 00:14:26.390 --> 00:14:27.590 It was the most effective, NOTE Confidence: 0.861194716923077 00:14:27.590 --> 00:14:30.201 it's pretty easy to implement and it's NOTE Confidence: 0.861194716923077 00:14:30.201 --> 00:14:32.289 the least expensive of the action, NOTE Confidence: 0.861194716923077 00:14:32.290 --> 00:14:35.080 actionable remedies and also it has NOTE Confidence: 0.861194716923077 00:14:35.080 --> 00:14:36.940 the smallest environmental footprint. NOTE Confidence: 0.861194716923077 00:14:36.940 --> 00:14:40.920 Of the the actionable remedies, NOTE Confidence: 0.861194716923077 00:14:40.920 --> 00:14:42.684 it's also worth pointing out that NOTE Confidence: 0.861194716923077 00:14:42.684 --> 00:14:44.780 sometimes when I show this case study, NOTE Confidence: 0.861194716923077 00:14:44.780 --> 00:14:46.046 people are surprised. NOTE Confidence: 0.861194716923077 00:14:46.046 --> 00:14:48.578 People say I would have assumed NOTE Confidence: 0.861194716923077 00:14:48.578 --> 00:14:50.941 that removal and off-site disposal NOTE Confidence: 0.861194716923077 00:14:50.941 --> 00:14:53.737 would have a higher footprint than NOTE Confidence: 0.861194716923077 00:14:53.811 --> 00:14:56.359 just putting in place a soil cover. NOTE Confidence: 0.861194716923077 00:14:56.360 --> 00:14:58.896 And it's one of the reasons it's so NOTE Confidence: 0.861194716923077 00:14:58.896 --> 00:15:01.083 important to conduct the assessment NOTE Confidence: 0.861194716923077 00:15:01.083 --> 00:15:02.370 because it changes, NOTE Confidence: 0.861194716923077 00:15:02.370 --> 00:15:04.740 it changes depending on the site. NOTE Confidence: 0.861194716923077 00:15:04.740 --> 00:15:07.176 It depends on where our fill material. NOTE Confidence: 0.84252904047619 00:15:07.180 --> 00:15:09.364 Is coming from where our waste material NOTE Confidence: 0.84252904047619 00:15:09.364 --> 00:15:11.533 is going if we're able to recycle NOTE Confidence: 0.84252904047619 00:15:11.533 --> 00:15:13.910 or reuse any of that waste material. NOTE Confidence: 0.84252904047619 00:15:13.910 --> 00:15:15.290 And so in just this example, NOTE Confidence: 0.84252904047619 00:15:15.290 --> 00:15:16.880 it didn't take very long, NOTE Confidence: 0.84252904047619 00:15:16.880 --> 00:15:19.848 about maybe 20 hours, maybe even less. NOTE Confidence: 0.84252904047619 00:15:19.850 --> 00:15:22.461 We were able to make an informed NOTE Confidence: 0.84252904047619 00:15:22.461 --> 00:15:24.936 decision and not make a decision NOTE Confidence: 0.84252904047619 00:15:24.936 --> 00:15:27.492 based on our biases or assumptions NOTE Confidence: 0.84252904047619 00:15:27.492 --> 00:15:30.285 about which alternative may or may NOTE Confidence: 0.84252904047619 00:15:30.285 --> 00:15:32.570 not have the largest footprint. NOTE Confidence: 0.84252904047619 00:15:32.570 --> 00:15:34.346 And sometimes it's just that simple, NOTE Confidence: 0.84252904047619 00:15:34.350 --> 00:15:36.678 but our next case study is NOTE Confidence: 0.84252904047619 00:15:36.678 --> 00:15:38.230 is not that simple. NOTE Confidence: 0.84252904047619 00:15:38.230 --> 00:15:41.338 It's an example where our footprint NOTE Confidence: 0.84252904047619 00:15:41.338 --> 00:15:44.053 analysis results did did not NOTE Confidence: 0.84252904047619 00:15:44.053 --> 00:15:47.371 align with the results of the NOTE Confidence: 0.84252904047619 00:15:47.371 --> 00:15:49.030 remaining evaluation criteria, NOTE Confidence: 0.84252904047619 00:15:49.030 --> 00:15:51.746 but they still proved to be really NOTE Confidence: 0.84252904047619 00:15:51.746 --> 00:15:53.989 beneficial and were really important NOTE Confidence: 0.84252904047619 00:15:53.989 --> 00:15:57.007 in our remedy selection and our NOTE Confidence: 0.84252904047619 00:15:57.007 --> 00:15:58.660 remedy implementation process. NOTE Confidence: 0.8262646575 00:16:03.180 --> 00:16:06.449 This site operated as a motor pool NOTE Confidence: 0.8262646575 00:16:06.449 --> 00:16:08.546 until 1988, and during that time they NOTE Confidence: 0.8262646575 00:16:08.546 --> 00:16:10.768 were using a lot of different solvents NOTE Confidence: 0.8262646575 00:16:10.768 --> 00:16:12.916 to clean parts and clean equipment. NOTE Confidence: 0.8262646575 00:16:12.920 --> 00:16:15.482 They were storing scrap and metal NOTE Confidence: 0.8262646575 00:16:15.482 --> 00:16:17.970 and vehicles and fuel bladders. NOTE Confidence: 0.8262646575 00:16:17.970 --> 00:16:20.148 And over the years we've identified NOTE Confidence: 0.8262646575 00:16:20.148 --> 00:16:22.950 teca T CE and their daughter products NOTE Confidence: 0.8262646575 00:16:22.950 --> 00:16:26.555 in soil and in groundwater and at some NOTE Confidence: 0.8262646575 00:16:26.555 --> 00:16:29.400 locations and pretty high concentrations. NOTE Confidence: 0.791363508 00:16:32.270 --> 00:16:34.342 During the remedy evaluation, NOTE Confidence: 0.791363508 00:16:34.342 --> 00:16:36.414 we were considering three NOTE Confidence: 0.791363508 00:16:36.414 --> 00:16:37.450 active alternatives. NOTE Confidence: 0.791363508 00:16:37.450 --> 00:16:39.834 We are considering enhanced NOTE Confidence: 0.791363508 00:16:39.834 --> 00:16:41.026 reductive defluorination, NOTE Confidence: 0.791363508 00:16:41.030 --> 00:16:44.090 ERD in situ chemical oxidation, NOTE Confidence: 0.791363508 00:16:44.090 --> 00:16:46.740 Isco, and horizontal air sparging, NOTE Confidence: 0.791363508 00:16:46.740 --> 00:16:49.768 which is shown here is HDAS, NOTE Confidence: 0.791363508 00:16:49.768 --> 00:16:52.756 and in our remedy evaluation document NOTE Confidence: 0.791363508 00:16:52.756 --> 00:16:55.940 we treated these results as just NOTE Confidence: 0.791363508 00:16:55.940 --> 00:16:58.615 another comparison criteria along with NOTE Confidence: 0.791363508 00:16:58.615 --> 00:17:03.590 the EPA's typical evaluation criteria. NOTE Confidence: 0.791363508 00:17:03.590 --> 00:17:05.036 And when we weighed them all, NOTE Confidence: 0.791363508 00:17:05.040 --> 00:17:07.420 when we looked at cost and we NOTE Confidence: 0.791363508 00:17:07.420 --> 00:17:09.387 looked at effectiveness and we NOTE Confidence: 0.791363508 00:17:09.387 --> 00:17:10.698 looked at implementability. NOTE Confidence: 0.791363508 00:17:10.700 --> 00:17:13.370 The choice we ultimately went NOTE Confidence: 0.791363508 00:17:13.370 --> 00:17:16.040 with was horizontal air sparging NOTE Confidence: 0.791363508 00:17:16.040 --> 00:17:18.880 and you can see here of the the NOTE Confidence: 0.791363508 00:17:18.880 --> 00:17:21.150 four alternatives are the three NOTE Confidence: 0.791363508 00:17:21.150 --> 00:17:22.136 active alternatives. NOTE Confidence: 0.791363508 00:17:22.140 --> 00:17:25.458 Horizontal air sparging had had the NOTE Confidence: 0.791363508 00:17:25.458 --> 00:17:27.117 highest environmental footprint. NOTE Confidence: 0.791363508 00:17:27.120 --> 00:17:29.822 But here's the thing that that's OK NOTE Confidence: 0.791363508 00:17:29.822 --> 00:17:32.745 because of a footprint or a remedy NOTE Confidence: 0.791363508 00:17:32.745 --> 00:17:35.938 is not sustainable if it's not also NOTE Confidence: 0.791363508 00:17:35.938 --> 00:17:38.928 affordable and effective and and NOTE Confidence: 0.791363508 00:17:38.928 --> 00:17:41.000 implementable, but we were able to. NOTE Confidence: 0.791363508 00:17:41.000 --> 00:17:44.036 Make an informed decision and also NOTE Confidence: 0.791363508 00:17:44.036 --> 00:17:46.747 use that information to continue NOTE Confidence: 0.791363508 00:17:46.747 --> 00:17:49.727 to make more informed decisions. NOTE Confidence: 0.791363508 00:17:49.730 --> 00:17:51.298 And and a lot of times when I NOTE Confidence: 0.791363508 00:17:51.298 --> 00:17:52.947 show this example people ask well, NOTE Confidence: 0.791363508 00:17:52.950 --> 00:17:54.924 well why did you choose it though NOTE Confidence: 0.791363508 00:17:54.924 --> 00:17:57.605 if it had the the the largest NOTE Confidence: 0.791363508 00:17:57.605 --> 00:17:59.482 environmental footprint and I will NOTE Confidence: 0.791363508 00:17:59.482 --> 00:18:02.120 say and in this case I think it was NOTE Confidence: 0.791363508 00:18:02.120 --> 00:18:04.214 because it was the least expensive NOTE Confidence: 0.791363508 00:18:04.214 --> 00:18:06.765 cost is a huge driving factor for NOTE Confidence: 0.791363508 00:18:06.765 --> 00:18:09.260 for a lot of remedies but equally NOTE Confidence: 0.791363508 00:18:09.260 --> 00:18:11.010 important if not more important. NOTE Confidence: 0.791363508 00:18:11.010 --> 00:18:12.726 Wasn't that it was known to NOTE Confidence: 0.791363508 00:18:12.726 --> 00:18:14.240 be effective at the site, NOTE Confidence: 0.791363508 00:18:14.240 --> 00:18:15.236 not just in theory, NOTE Confidence: 0.791363508 00:18:15.236 --> 00:18:17.500 but we we had done a pilot study NOTE Confidence: 0.791363508 00:18:17.500 --> 00:18:19.270 with the horizontal air sparge NOTE Confidence: 0.791363508 00:18:19.270 --> 00:18:21.460 which had been really effective. NOTE Confidence: 0.791363508 00:18:21.460 --> 00:18:23.284 So all the stakeholders were really NOTE Confidence: 0.791363508 00:18:23.284 --> 00:18:25.240 comfortable with it as a technology. NOTE Confidence: 0.9305457075 00:18:28.050 --> 00:18:29.850 But like I said, we we said OK, NOTE Confidence: 0.9305457075 00:18:29.850 --> 00:18:32.867 we've got the details for this remedy. NOTE Confidence: 0.9305457075 00:18:32.870 --> 00:18:34.974 So, so let's look at it more closely NOTE Confidence: 0.9305457075 00:18:34.974 --> 00:18:37.184 to get to the bottom of where NOTE Confidence: 0.9305457075 00:18:37.184 --> 00:18:38.804 these impacts are coming from. NOTE Confidence: 0.9305457075 00:18:38.810 --> 00:18:41.336 You can see immediately this purple NOTE Confidence: 0.9305457075 00:18:41.336 --> 00:18:43.871 bar that's that's equipment use and NOTE Confidence: 0.9305457075 00:18:43.871 --> 00:18:45.811 ultimately that's from operation of NOTE Confidence: 0.9305457075 00:18:45.811 --> 00:18:48.270 the air sparge system that's that's NOTE Confidence: 0.9305457075 00:18:48.270 --> 00:18:51.126 electricity use and what this is showing NOTE Confidence: 0.9305457075 00:18:51.130 --> 00:18:55.008 us is where we have the greatest NOTE Confidence: 0.9305457075 00:18:55.008 --> 00:18:58.209 opportunity to reduce our footprint. NOTE Confidence: 0.9305457075 00:18:58.210 --> 00:19:01.138 And as we move from a remedy evaluation NOTE Confidence: 0.9305457075 00:19:01.138 --> 00:19:03.888 to remedy design and implementation, NOTE Confidence: 0.9305457075 00:19:03.890 --> 00:19:06.978 one of the most important actions we took NOTE Confidence: 0.9305457075 00:19:06.978 --> 00:19:09.927 with this information was to establish NOTE Confidence: 0.9305457075 00:19:09.927 --> 00:19:13.065 criteria for air sparge system shutdown. NOTE Confidence: 0.9305457075 00:19:13.070 --> 00:19:15.305 We established at the time NOTE Confidence: 0.9305457075 00:19:15.305 --> 00:19:16.646 of remedy implementation, NOTE Confidence: 0.9305457075 00:19:16.650 --> 00:19:18.870 before it was ever turned on, NOTE Confidence: 0.9305457075 00:19:18.870 --> 00:19:22.391 that our air sparging would be discontinued NOTE Confidence: 0.9305457075 00:19:22.391 --> 00:19:25.102 when our contaminants were reduced below NOTE Confidence: 0.9305457075 00:19:25.102 --> 00:19:28.250 100 PPB within 50 feet of the wells, NOTE Confidence: 0.9305457075 00:19:28.250 --> 00:19:31.130 or when our contaminant reductions NOTE Confidence: 0.9305457075 00:19:31.130 --> 00:19:34.010 began to demonstrate asymptotic trends. NOTE Confidence: 0.9305457075 00:19:34.010 --> 00:19:35.345 And in particular, NOTE Confidence: 0.9305457075 00:19:35.345 --> 00:19:37.570 this latter option provided us NOTE Confidence: 0.9305457075 00:19:37.570 --> 00:19:39.230 the flexibility to discontinue NOTE Confidence: 0.9305457075 00:19:39.230 --> 00:19:41.673 the remedy in the event that the NOTE Confidence: 0.9305457075 00:19:41.673 --> 00:19:43.739 air sparge does not perform. NOTE Confidence: 0.9305457075 00:19:43.740 --> 00:19:45.860 A way that we expect. NOTE Confidence: 0.9305457075 00:19:45.860 --> 00:19:47.900 And and this might seem simple, NOTE Confidence: 0.9305457075 00:19:47.900 --> 00:19:50.640 maybe this even seems obvious, NOTE Confidence: 0.9305457075 00:19:50.640 --> 00:19:54.224 but how many times have you seen systems NOTE Confidence: 0.9305457075 00:19:54.224 --> 00:19:57.404 limp along with with no real benefit NOTE Confidence: 0.9305457075 00:19:57.404 --> 00:20:00.920 because we didn't have a plan in place? NOTE Confidence: 0.9305457075 00:20:00.920 --> 00:20:02.640 I've heard people say and NOTE Confidence: 0.9305457075 00:20:02.640 --> 00:20:04.360 maybe you have as well. NOTE Confidence: 0.9305457075 00:20:04.360 --> 00:20:04.645 Well, NOTE Confidence: 0.9305457075 00:20:04.645 --> 00:20:06.355 the the remedy may not really NOTE Confidence: 0.9305457075 00:20:06.355 --> 00:20:07.560 be doing that much, NOTE Confidence: 0.9305457075 00:20:07.560 --> 00:20:09.884 but but let's just leave it on NOTE Confidence: 0.9305457075 00:20:09.884 --> 00:20:12.159 because it's not hurting anything. NOTE Confidence: 0.9305457075 00:20:12.160 --> 00:20:13.996 But we can use our calculations, NOTE Confidence: 0.9305457075 00:20:14.000 --> 00:20:16.448 we can use these footprint analysis NOTE Confidence: 0.9305457075 00:20:16.448 --> 00:20:19.777 tools to show that it is in fact NOTE Confidence: 0.9305457075 00:20:19.777 --> 00:20:21.792 hurting something for this system. NOTE Confidence: 0.9305457075 00:20:21.800 --> 00:20:24.653 For every year that we leave the system on, NOTE Confidence: 0.9305457075 00:20:24.660 --> 00:20:27.084 once we have reached the point NOTE Confidence: 0.9305457075 00:20:27.084 --> 00:20:29.160 of diminishing returns, we have, NOTE Confidence: 0.9305457075 00:20:29.160 --> 00:20:31.740 we have a really large environmental NOTE Confidence: 0.9305457075 00:20:31.740 --> 00:20:33.716 footprint and we also have NOTE Confidence: 0.9305457075 00:20:33.716 --> 00:20:35.446 a really large price tag. NOTE Confidence: 0.9305457075 00:20:35.450 --> 00:20:37.790 And to make it very, NOTE Confidence: 0.9305457075 00:20:37.790 --> 00:20:38.458 very clear, NOTE Confidence: 0.9305457075 00:20:38.458 --> 00:20:40.462 this impact is having is happening NOTE Confidence: 0.9305457075 00:20:40.462 --> 00:20:41.130 every year. NOTE Confidence: 0.9305457075 00:20:41.130 --> 00:20:42.650 It's happening when the system's NOTE Confidence: 0.9305457075 00:20:42.650 --> 00:20:43.866 effective and it's happening NOTE Confidence: 0.9305457075 00:20:43.866 --> 00:20:45.467 when the system's not effective, NOTE Confidence: 0.9305457075 00:20:45.470 --> 00:20:46.950 but when it's not working, NOTE Confidence: 0.9305457075 00:20:46.950 --> 00:20:49.946 when it's reached its end of life, NOTE Confidence: 0.9305457075 00:20:49.950 --> 00:20:52.146 then we don't want to be NOTE Confidence: 0.9305457075 00:20:52.146 --> 00:20:54.290 continuing to have these impacts. NOTE Confidence: 0.9305457075 00:20:54.290 --> 00:20:55.720 We're not talking about turning NOTE Confidence: 0.9305457075 00:20:55.720 --> 00:20:56.864 the system off early. NOTE Confidence: 0.9305457075 00:20:56.870 --> 00:21:01.350 We're not talking about turning it off well. NOTE Confidence: 0.9305457075 00:21:01.350 --> 00:21:03.605 It's treating these really high NOTE Confidence: 0.9305457075 00:21:03.605 --> 00:21:05.409 concentrations we're talking about. NOTE Confidence: 0.9305457075 00:21:05.410 --> 00:21:08.858 Turning it off once it's done its job. NOTE Confidence: 0.9305457075 00:21:08.860 --> 00:21:12.208 And this information was a really NOTE Confidence: 0.9305457075 00:21:12.208 --> 00:21:15.658 important line of evidence to show why. NOTE Confidence: 0.9305457075 00:21:15.660 --> 00:21:19.860 These milestones were just so critical. NOTE Confidence: 0.9305457075 00:21:19.860 --> 00:21:21.876 Now in this presentation I've thrown NOTE Confidence: 0.9305457075 00:21:21.876 --> 00:21:24.511 out a lot of greenhouse gas emissions NOTE Confidence: 0.9305457075 00:21:24.511 --> 00:21:27.346 values and in terms of metric tons NOTE Confidence: 0.9305457075 00:21:27.418 --> 00:21:29.842 and and perhaps those numbers have NOTE Confidence: 0.9305457075 00:21:29.842 --> 00:21:32.203 resonated with you or perhaps you've NOTE Confidence: 0.9305457075 00:21:32.203 --> 00:21:35.343 looked at them and said 1400 metric tons. NOTE Confidence: 0.9305457075 00:21:35.343 --> 00:21:36.987 Is that a lot? NOTE Confidence: 0.9305457075 00:21:36.990 --> 00:21:38.734 Is that a little? NOTE Confidence: 0.9305457075 00:21:38.734 --> 00:21:40.914 What do these numbers mean? NOTE Confidence: 0.9305457075 00:21:40.920 --> 00:21:43.144 And so one thing that we like to NOTE Confidence: 0.9305457075 00:21:43.144 --> 00:21:45.235 do is to use the the EPA's. NOTE Confidence: 0.9305457075 00:21:45.235 --> 00:21:45.670 Equivalencies, NOTE Confidence: 0.9305457075 00:21:45.670 --> 00:21:46.105 calculators. NOTE Confidence: 0.9305457075 00:21:46.105 --> 00:21:49.150 This is a website where you go NOTE Confidence: 0.9305457075 00:21:49.220 --> 00:21:51.558 in and you can put in different NOTE Confidence: 0.9305457075 00:21:51.558 --> 00:21:52.560 types of emissions NOTE Confidence: 0.902750251 00:21:52.636 --> 00:21:54.964 and it'll tell you what those NOTE Confidence: 0.902750251 00:21:54.964 --> 00:21:56.516 emissions are equivalent to. NOTE Confidence: 0.902750251 00:21:56.520 --> 00:21:58.248 So that's what I did with NOTE Confidence: 0.902750251 00:21:58.248 --> 00:21:59.263 these 1400 metric tons, NOTE Confidence: 0.902750251 00:21:59.263 --> 00:22:01.339 and this is what I got out of it. NOTE Confidence: 0.902750251 00:22:01.340 --> 00:22:03.260 It said that these 1400 NOTE Confidence: 0.902750251 00:22:03.260 --> 00:22:05.180 metric tons of greenhouse gas NOTE Confidence: 0.902750251 00:22:05.253 --> 00:22:07.498 emissions are equivalent to the NOTE Confidence: 0.902750251 00:22:07.500 --> 00:22:09.948 CO2 emissions from consuming NOTE Confidence: 0.916547185555556 00:22:13.140 --> 00:22:15.928 157,533 gallons of gasoline. NOTE Confidence: 0.916547185555556 00:22:15.928 --> 00:22:19.413 Or on the flip side, NOTE Confidence: 0.916547185555556 00:22:19.420 --> 00:22:21.588 these amount of emissions. NOTE Confidence: 0.916547185555556 00:22:21.588 --> 00:22:23.756 These emissions would require NOTE Confidence: 0.87960942882353 00:22:26.320 --> 00:22:29.464 23,149 tree seedlings grown for 10 NOTE Confidence: 0.87960942882353 00:22:29.464 --> 00:22:33.464 years to sequester all of the carbon NOTE Confidence: 0.87960942882353 00:22:33.464 --> 00:22:35.880 associated with those emissions. NOTE Confidence: 0.87960942882353 00:22:35.880 --> 00:22:37.154 So if you haven't seen that before, NOTE Confidence: 0.87960942882353 00:22:37.160 --> 00:22:38.455 I encourage you to check it out. NOTE Confidence: 0.87960942882353 00:22:38.460 --> 00:22:40.868 It's a great way to to translate this NOTE Confidence: 0.87960942882353 00:22:40.868 --> 00:22:43.416 this sort of technical number for NOTE Confidence: 0.87960942882353 00:22:43.416 --> 00:22:46.320 for different stakeholders. Who who? NOTE Confidence: 0.87960942882353 00:22:46.320 --> 00:22:49.854 May resonate more with with these NOTE Confidence: 0.87960942882353 00:22:49.854 --> 00:22:51.994 other values versus just metric NOTE Confidence: 0.87960942882353 00:22:51.994 --> 00:22:54.879 tons of greenhouse gas emissions. NOTE Confidence: 0.87960942882353 00:22:54.880 --> 00:22:59.430 Which brings us to our key takeaways. NOTE Confidence: 0.87960942882353 00:22:59.430 --> 00:23:03.750 What tool should you use? NOTE Confidence: 0.87960942882353 00:23:03.750 --> 00:23:06.714 Either one, both of these tools NOTE Confidence: 0.87960942882353 00:23:06.714 --> 00:23:09.332 have well documented methodology and NOTE Confidence: 0.87960942882353 00:23:09.332 --> 00:23:11.556 they're using reputable sources. NOTE Confidence: 0.87960942882353 00:23:11.560 --> 00:23:15.080 Over all the the results are really similar. NOTE Confidence: 0.87960942882353 00:23:15.080 --> 00:23:17.698 Between the two there, there were three. NOTE Confidence: 0.87960942882353 00:23:17.700 --> 00:23:19.084 They're both open source, NOTE Confidence: 0.87960942882353 00:23:19.084 --> 00:23:20.814 they're both easy to learn. NOTE Confidence: 0.87960942882353 00:23:20.820 --> 00:23:23.084 I mean my argument is always going to NOTE Confidence: 0.87960942882353 00:23:23.084 --> 00:23:25.487 be just do the assessment whether you're NOTE Confidence: 0.87960942882353 00:23:25.487 --> 00:23:28.578 using site wise or safe or proprietary tool. NOTE Confidence: 0.87960942882353 00:23:28.580 --> 00:23:31.145 We need to set goals and we need to NOTE Confidence: 0.87960942882353 00:23:31.145 --> 00:23:33.696 measure our progress against those goals. NOTE Confidence: 0.87960942882353 00:23:33.700 --> 00:23:34.840 If you're considering which NOTE Confidence: 0.87960942882353 00:23:34.840 --> 00:23:36.830 of these two you want to use, NOTE Confidence: 0.87960942882353 00:23:36.830 --> 00:23:38.456 really think about what you're going NOTE Confidence: 0.87960942882353 00:23:38.456 --> 00:23:40.467 to want to use it for and also NOTE Confidence: 0.87960942882353 00:23:40.467 --> 00:23:42.360 whether you want to be in alignment. NOTE Confidence: 0.87960942882353 00:23:42.360 --> 00:23:45.657 With the the EPA S ASTM footwork NOTE Confidence: 0.87960942882353 00:23:45.657 --> 00:23:47.070 and and framework, NOTE Confidence: 0.87960942882353 00:23:47.070 --> 00:23:50.580 but I I don't think you can go wrong with. NOTE Confidence: 0.87960942882353 00:23:50.580 --> 00:23:52.210 With either of these tools. NOTE Confidence: 0.91061863125 00:23:54.260 --> 00:23:56.954 It's also important that we consider NOTE Confidence: 0.91061863125 00:23:56.954 --> 00:23:59.425 the challenges that are associated NOTE Confidence: 0.91061863125 00:23:59.425 --> 00:24:02.415 with these footprints analysis tools. NOTE Confidence: 0.91061863125 00:24:02.420 --> 00:24:05.940 The first being that both sidewise and CFA NOTE Confidence: 0.91061863125 00:24:05.940 --> 00:24:09.356 were designed to calculate the environmental NOTE Confidence: 0.91061863125 00:24:09.356 --> 00:24:12.416 footprint of our remedial alternatives. NOTE Confidence: 0.91061863125 00:24:12.420 --> 00:24:15.604 And we all know that environment is just NOTE Confidence: 0.91061863125 00:24:15.604 --> 00:24:19.269 one part of of the triple bottom line and NOTE Confidence: 0.91061863125 00:24:19.269 --> 00:24:22.142 we're not taking into account societal NOTE Confidence: 0.91061863125 00:24:22.142 --> 00:24:25.334 impacts and we're not taking account. NOTE Confidence: 0.91061863125 00:24:25.340 --> 00:24:26.536 Economic impacts? NOTE Confidence: 0.91061863125 00:24:26.536 --> 00:24:30.124 Because these tools are so flexible, NOTE Confidence: 0.91061863125 00:24:30.130 --> 00:24:33.562 there's a few ways that you can include NOTE Confidence: 0.91061863125 00:24:33.562 --> 00:24:35.990 societal and economic benefits, NOTE Confidence: 0.91061863125 00:24:35.990 --> 00:24:37.566 but but at the end of the day, NOTE Confidence: 0.91061863125 00:24:37.570 --> 00:24:40.228 they're both environmental NOTE Confidence: 0.91061863125 00:24:40.228 --> 00:24:42.886 footprint analysis tools, NOTE Confidence: 0.91061863125 00:24:42.890 --> 00:24:46.796 so so that really is a limitation. NOTE Confidence: 0.91061863125 00:24:46.800 --> 00:24:48.992 It's worth considering that NOTE Confidence: 0.91061863125 00:24:48.992 --> 00:24:51.732 our project size does matter. NOTE Confidence: 0.91061863125 00:24:51.740 --> 00:24:55.236 If a project is is just really small, NOTE Confidence: 0.91061863125 00:24:55.240 --> 00:24:59.034 it could be a waste of resources. NOTE Confidence: 0.91061863125 00:24:59.040 --> 00:25:01.278 I think probably more likely is NOTE Confidence: 0.91061863125 00:25:01.278 --> 00:25:03.998 that a project be be too complex. NOTE Confidence: 0.91061863125 00:25:04.000 --> 00:25:06.496 Or if the project is not too complex, NOTE Confidence: 0.91061863125 00:25:06.500 --> 00:25:08.620 then our needs, our requirements, NOTE Confidence: 0.91061863125 00:25:08.620 --> 00:25:10.636 what we need to get out of NOTE Confidence: 0.91061863125 00:25:10.636 --> 00:25:12.200 it are two complex. NOTE Confidence: 0.91061863125 00:25:12.200 --> 00:25:15.232 In that situation we might move from a NOTE Confidence: 0.91061863125 00:25:15.232 --> 00:25:17.457 footprint analysis tool to a life cycle. NOTE Confidence: 0.91061863125 00:25:17.460 --> 00:25:19.488 Assessment or LCA tool? NOTE Confidence: 0.91061863125 00:25:19.488 --> 00:25:23.751 And then our last challenge is, is both a? NOTE Confidence: 0.91061863125 00:25:23.751 --> 00:25:28.640 A pro and a con that it's so easy to learn, NOTE Confidence: 0.91061863125 00:25:28.640 --> 00:25:29.402 easy to use, NOTE Confidence: 0.91061863125 00:25:29.402 --> 00:25:31.420 it's great it it's easy to pick up, NOTE Confidence: 0.91061863125 00:25:31.420 --> 00:25:34.437 easy for the novice practitioner to use. NOTE Confidence: 0.91061863125 00:25:34.440 --> 00:25:36.930 We have seen instances where someone NOTE Confidence: 0.91061863125 00:25:36.930 --> 00:25:39.220 who isn't familiar with it does, NOTE Confidence: 0.91061863125 00:25:39.220 --> 00:25:40.600 doesn't think incorrectly, NOTE Confidence: 0.91061863125 00:25:40.600 --> 00:25:41.980 makes a mistake, NOTE Confidence: 0.91061863125 00:25:41.980 --> 00:25:43.267 maybe double input, NOTE Confidence: 0.91061863125 00:25:43.267 --> 00:25:45.412 something and and their footprint NOTE Confidence: 0.91061863125 00:25:45.412 --> 00:25:47.546 comes out orders of magnitude NOTE Confidence: 0.91061863125 00:25:47.546 --> 00:25:50.360 different than what it is in actuality, NOTE Confidence: 0.91061863125 00:25:50.360 --> 00:25:52.535 and they're not practiced enough NOTE Confidence: 0.91061863125 00:25:52.535 --> 00:25:54.275 to to recognize that. NOTE Confidence: 0.91061863125 00:25:54.280 --> 00:25:57.448 That can be a a drawback, NOTE Confidence: 0.91061863125 00:25:57.450 --> 00:26:00.514 um and and it can take an advanced NOTE Confidence: 0.91061863125 00:26:00.514 --> 00:26:03.200 practitioner to harness that full power. NOTE Confidence: 0.91061863125 00:26:03.200 --> 00:26:05.078 In my opinion, NOTE Confidence: 0.91061863125 00:26:05.078 --> 00:26:08.208 the benefit outweighs those risks. NOTE Confidence: 0.91061863125 00:26:08.210 --> 00:26:10.933 Because ultimately what these are are are NOTE Confidence: 0.91061863125 00:26:10.933 --> 00:26:13.599 powerful tools and they've got many uses. NOTE Confidence: 0.91061863125 00:26:13.600 --> 00:26:15.728 We can use them to compare entities. NOTE Confidence: 0.91061863125 00:26:15.730 --> 00:26:18.202 We can use them to evaluate NOTE Confidence: 0.91061863125 00:26:18.202 --> 00:26:19.026 individual alternatives. NOTE Confidence: 0.91061863125 00:26:19.030 --> 00:26:22.216 We can use them to calculate NOTE Confidence: 0.91061863125 00:26:22.216 --> 00:26:23.809 our footprint savings. NOTE Confidence: 0.91061863125 00:26:23.810 --> 00:26:25.694 And despite all of the information NOTE Confidence: 0.91061863125 00:26:25.694 --> 00:26:27.429 from the tool that we get, NOTE Confidence: 0.91061863125 00:26:27.430 --> 00:26:30.734 we found it to be a really cost NOTE Confidence: 0.91061863125 00:26:30.734 --> 00:26:33.108 effective method across the board. NOTE Confidence: 0.91061863125 00:26:33.110 --> 00:26:35.525 I've said it before a highlighted again, NOTE Confidence: 0.91061863125 00:26:35.530 --> 00:26:36.502 it's really flexible, NOTE Confidence: 0.91061863125 00:26:36.502 --> 00:26:38.446 so we can improve that footprint. NOTE Confidence: 0.91061863125 00:26:38.450 --> 00:26:38.793 Accuracy. NOTE Confidence: 0.91061863125 00:26:38.793 --> 00:26:41.537 Or we can use it in different regions NOTE Confidence: 0.91061863125 00:26:41.537 --> 00:26:43.979 or or with different products that NOTE Confidence: 0.91061863125 00:26:43.979 --> 00:26:46.420 are already included in the tool. NOTE Confidence: 0.91061863125 00:26:46.420 --> 00:26:47.880 And because of that, NOTE Confidence: 0.91061863125 00:26:47.880 --> 00:26:49.705 we've got additional lines of NOTE Confidence: 0.91061863125 00:26:49.705 --> 00:26:51.438 evidence for remedy selection. NOTE Confidence: 0.91061863125 00:26:51.440 --> 00:26:53.740 We've got additional areas of NOTE Confidence: 0.91061863125 00:26:53.740 --> 00:26:56.040 opportunity and we're able to NOTE Confidence: 0.91061863125 00:26:56.123 --> 00:26:58.697 identify them and we're also able NOTE Confidence: 0.91061863125 00:26:58.697 --> 00:27:01.087 to calculate and take credit NOTE Confidence: 0.91061863125 00:27:01.087 --> 00:27:03.459 for those footprint reductions. NOTE Confidence: 0.91061863125 00:27:03.460 --> 00:27:05.572 If you're interested in in learning NOTE Confidence: 0.91061863125 00:27:05.572 --> 00:27:07.581 more or or figuring out how NOTE Confidence: 0.91061863125 00:27:07.581 --> 00:27:09.165 to use site wise or sifa, NOTE Confidence: 0.91061863125 00:27:09.170 --> 00:27:10.990 they both have really NOTE Confidence: 0.91061863125 00:27:10.990 --> 00:27:12.355 robust training manuals. NOTE Confidence: 0.91061863125 00:27:12.360 --> 00:27:14.480 But also I wanted to let you all NOTE Confidence: 0.91061863125 00:27:14.480 --> 00:27:16.403 know that the Sustainable Remediation NOTE Confidence: 0.91061863125 00:27:16.403 --> 00:27:18.613 Forum just last year developed NOTE Confidence: 0.91061863125 00:27:18.613 --> 00:27:20.491 some really short training videos NOTE Confidence: 0.91061863125 00:27:20.491 --> 00:27:22.981 on how to use both of these tools. NOTE Confidence: 0.91061863125 00:27:22.981 --> 00:27:24.586 These are just some snapshots. NOTE Confidence: 0.91061863125 00:27:24.590 --> 00:27:26.525 Each of these training series NOTE Confidence: 0.91061863125 00:27:26.525 --> 00:27:28.460 has more videos than this, NOTE Confidence: 0.875949473125 00:27:28.460 --> 00:27:30.260 but what you'll notice is that NOTE Confidence: 0.875949473125 00:27:30.260 --> 00:27:31.850 they're really short and that's NOTE Confidence: 0.875949473125 00:27:31.850 --> 00:27:33.490 because we wanted each video. NOTE Confidence: 0.875949473125 00:27:33.490 --> 00:27:35.905 To just be on one specific task. NOTE Confidence: 0.875949473125 00:27:35.910 --> 00:27:37.440 So if you're new you can NOTE Confidence: 0.875949473125 00:27:37.440 --> 00:27:38.460 start at the beginning, NOTE Confidence: 0.875949473125 00:27:38.460 --> 00:27:40.503 but if you're just getting stuck on one step, NOTE Confidence: 0.875949473125 00:27:40.510 --> 00:27:43.048 you can go and you can go right to NOTE Confidence: 0.875949473125 00:27:43.048 --> 00:27:45.687 that step really quickly and and NOTE Confidence: 0.875949473125 00:27:45.687 --> 00:27:47.967 hopefully get through through that. NOTE Confidence: 0.875949473125 00:27:47.970 --> 00:27:50.787 I will say I'm not sure how YouTube works NOTE Confidence: 0.875949473125 00:27:50.787 --> 00:27:53.300 being accessed in different countries, NOTE Confidence: 0.875949473125 00:27:53.300 --> 00:27:55.820 so please, if you have any trouble NOTE Confidence: 0.875949473125 00:27:55.820 --> 00:27:57.290 accessing our YouTube page, NOTE Confidence: 0.875949473125 00:27:57.290 --> 00:27:59.404 don't hesitate to reach out to me.

NOTE Confidence: 0.925578625 00:28:11.290 --> 00:28:13.054 Which does bring me to the NOTE Confidence: 0.925578625 00:28:13.054 --> 00:28:14.632 end of my presentation. Again, NOTE Confidence: 0.925578625 00:28:14.632 --> 00:28:17.446 thank you so much for this opportunity. NOTE Confidence: 0.925578625 00:28:17.450 --> 00:28:19.150 My e-mail address is here.

NOTE Confidence: 0.925578625 00:28:31.770 --> 00:28:33.305 It's something I'm really passionate NOTE Confidence: 0.925578625 00:28:33.305 --> 00:28:35.110 about and would be happy to NOTE Confidence: 0.925578625 00:28:35.110 --> 00:28:36.608 talk to you about at any point.
