WEBVTT 00:07.440 --> 00:10.620 So our core dam safety program 00:10.630 --> 00:12.950 involves a lot of different aspects . 00:13.110 --> 00:16.240 I'll see . There are a lot of tasks 00:16.240 --> 00:18.020 which are repeated annually and 00:18.020 --> 00:20.650 concurring on an ongoing . Those would 00:20.650 --> 00:22.840 involve things like the reading of 00:22.840 --> 00:24.507 instrumentation at our dams , 00:24.507 --> 00:26.507 monitoring the health of our dams , 00:26.507 --> 00:28.520 doing reports associated with that 00:28.610 --> 00:31.160 performing inspections , both annual 00:31.160 --> 00:33.020 inspections and more detailed 00:33.020 --> 00:35.590 inspections on a less frequent basis . 00:36.070 --> 00:38.292 So we have inspection program , we have 00:38.292 --> 00:40.126 a monitoring and instrumentation 00:40.126 --> 00:43.380 program . Uh We also have a robust 00:43.390 --> 00:45.650 design and construction program to 00:45.660 --> 00:48.910 improve and rehabilitate things that 00:48.920 --> 00:51.160 get older and deteriorated our dams . 00:51.750 --> 00:53.639 And then there was a lot of other 00:53.639 --> 00:57.300 things like we do emergency Action plan 00:57.310 --> 00:59.532 preparation or water management Group , 00:59.532 --> 01:01.699 does a lot of that and we're with them 01:01.699 --> 01:03.921 in Geo Tech branch . So that's all down 01:03.921 --> 01:06.143 safety , making sure we have plans that 01:06.143 --> 01:08.254 should something go wrong at a dam or 01:08.254 --> 01:10.199 even if not something is not going 01:10.199 --> 01:12.366 wrong if we have spillway flow , which 01:12.366 --> 01:14.588 is the proper performance of a , but it 01:14.588 --> 01:16.643 releases a lot of water downstream . 01:16.643 --> 01:18.810 How we would notify people who to call 01:18.810 --> 01:20.921 uh and work with downstream emergency 01:20.921 --> 01:22.921 responders and emergency management 01:22.921 --> 01:24.977 office preparing those plans , doing 01:24.977 --> 01:27.032 exercises to go through with our dam 01:27.032 --> 01:28.921 operators and all those different 01:28.921 --> 01:31.088 organizations , both core and external 01:31.088 --> 01:33.254 of the core as to how we would respond 01:33.254 --> 01:35.820 in a situation . Uh We were involved a 01:35.820 --> 01:38.153 lot with that in the dam safety program . 01:38.153 --> 01:41.220 And then there's just a lots of other 01:41.220 --> 01:43.980 things that prop up . We do uh pretty 01:43.980 --> 01:46.460 robust risk studies on a periodic basis 01:46.460 --> 01:48.930 for dance as well , reassessing the 01:48.930 --> 01:50.708 health of the dam , making sure 01:50.708 --> 01:52.374 something hasn't changed that 01:52.374 --> 01:54.760 jeopardizes the public in a different 01:54.760 --> 01:56.982 way due to new development downstream . 01:56.982 --> 01:58.760 Those sorts of things . So that 01:58.760 --> 02:00.427 involves a lot of engineering 02:00.427 --> 02:02.593 assessment as well as getting products 02:02.593 --> 02:04.970 from certain agencies or certain 02:04.970 --> 02:07.026 organizations within the core of the 02:07.026 --> 02:08.859 support that , such as new flood 02:08.859 --> 02:10.803 mapping and inundation mapping and 02:10.803 --> 02:13.026 consequence analysis downstream for the 02:13.026 --> 02:14.859 public , that sort of thing . So 02:14.859 --> 02:17.081 there's a lot of missions of dam safety 02:17.081 --> 02:20.680 pretty widespread . We have 15 02:20.680 --> 02:24.600 dams that we take care of . Ah so 02:24.600 --> 02:26.267 we have what we call periodic 02:26.267 --> 02:28.211 inspections on a five year basis . 02:28.211 --> 02:30.211 Those periodic inspections are very 02:30.211 --> 02:32.170 robust inspections which include 02:32.180 --> 02:34.770 geotechnical engineers , geologists , 02:34.780 --> 02:37.430 structural mechanical electrical 02:37.430 --> 02:39.597 engineers . We look at all the systems 02:39.597 --> 02:41.763 in the dams , we go up tunnels , we go 02:41.763 --> 02:43.930 in towers , we look at everything . So 02:43.930 --> 02:46.880 uh those form the basis of identifying 02:46.880 --> 02:49.460 any deterioration or issues at the dam 02:49.940 --> 02:53.750 that require upgrades or construction 02:53.750 --> 02:55.900 or measures to address and make sure 02:55.900 --> 02:58.680 the dam is staying and it's originally 02:58.680 --> 03:02.050 intended condition to be in great shape 03:02.060 --> 03:04.810 and perform as expected . So , those 03:04.810 --> 03:07.032 periodic inspections are really the key 03:07.032 --> 03:09.088 to that , to addressing those issues 03:09.088 --> 03:11.199 and they inform our budgeting process 03:11.199 --> 03:13.532 and what projects come along to do that . 03:13.532 --> 03:15.254 Uh And of course we assess our 03:15.254 --> 03:17.588 instrumentation and all as part of that . 03:17.588 --> 03:19.980 Uh The in addition to those five year 03:19.980 --> 03:22.470 inspections , we also come to all of 03:22.470 --> 03:25.730 the dams and really , uh again each 03:25.730 --> 03:27.841 year we're only going to a handful of 03:27.841 --> 03:29.730 dams for those five year detailed 03:29.730 --> 03:31.952 inspections , but then we also come out 03:31.952 --> 03:34.174 and we walk the dams fully , especially 03:34.174 --> 03:37.150 the embankments on an annual basis , 03:37.150 --> 03:39.261 and coordinate with the dam operators 03:39.261 --> 03:41.317 during those trips , take instrument 03:41.317 --> 03:43.430 readings , just look whether anything 03:43.430 --> 03:46.010 is out of the ordinary . Talk to the 03:46.010 --> 03:48.232 dam operators about what they're seeing 03:48.232 --> 03:50.399 every day for our five year . Periodic 03:50.399 --> 03:53.170 inspections takes about a day , but 03:53.170 --> 03:55.226 there's there's months worth of work 03:55.540 --> 03:57.651 beyond that , in both the preparation 03:57.651 --> 04:00.330 and coordination in advance . And we 04:00.330 --> 04:03.120 write very thorough quality , robust 04:03.120 --> 04:05.560 reports after that . Uh And that takes 04:05.560 --> 04:07.380 weeks and weeks of effort and 04:07.380 --> 04:09.380 preparation for those reporting and 04:09.380 --> 04:11.269 reviews , uh and how we track the 04:11.269 --> 04:13.491 recommendations that come out of that . 04:13.491 --> 04:15.720 So for our annual inspections that are 04:15.720 --> 04:18.390 more JIA , technically based that we do 04:18.390 --> 04:20.600 it all of our dams that usually 04:20.600 --> 04:23.960 involves , I would say 04:23.970 --> 04:27.380 2-4 people that would come out on an 04:27.380 --> 04:29.440 annual basis and walk with the dam 04:29.440 --> 04:31.700 operators do inspections and 04:31.740 --> 04:33.830 documenting site visit reports what 04:33.830 --> 04:34.830 we're seeing . 04:37.840 --> 04:41.660 Mhm . Yeah . Mhm . Mhm . 04:42.140 --> 04:45.740 Yeah . Yeah . Mhm . Yeah . 04:47.040 --> 04:50.740 Yeah . Yeah . Yeah . 04:52.640 --> 04:53.640 Yeah . 05:02.540 --> 05:05.960 Yeah . Yeah . Yeah .
