00:00:05.600 a natural gas compressor station like we 00:00:08.35000:00:08.360 write here today is a transmission relay 00:00:10.51000:00:10.520 station our we have thousands of miles 00:00:12.94000:00:12.950 of gas transmission pipeline in the 00:00:15.54900:00:15.559 Northeast as the customers take gas off 00:00:17.95000:00:17.960 the pipeline system the pressure is 00:00:19.93000:00:19.940 reduced so we have to add the 00:00:21.64000:00:21.650 transmission relay compressor stations 00:00:23.80000:00:23.810 to boost the pressure in the pipeline it 00:00:26.05000:00:26.060 comes in through a suction line into the 00:00:28.02900:00:28.039 compressor station it goes through a 00:00:30.16000:00:30.170 filter separator element that we have 00:00:32.65000:00:32.660 that takes out any impurities that might 00:00:35.08000:00:35.090 be in the gas the compressor basically 00:00:37.33000:00:37.340 is driven by an engine in this case a 00:00:39.48900:00:39.499 turbine the gas goes into the compressor 00:00:42.04000:00:42.050 it boosts the pressure at when it's in 00:00:44.38000:00:44.390 the compressor and goes back out into a 00:00:46.63000:00:46.640 discharge line from the station it goes 00:00:49.29900:00:49.309 back into the main pipeline at down on a 00:00:52.47900:00:52.489 downstream side at a higher pressure 00:01:01.76000:01:01.770 we've gone to a primarily utilization of 00:01:04.96900:01:04.979 solar turbine solar turbines from our 00:01:08.33000:01:08.340 standpoint our our state-of-the-art 00:01:10.39000:01:10.400 equipment they have what they call a low 00:01:13.52000:01:13.530 emissions package the Dominion buys from 00:01:15.80000:01:15.810 them 00:01:16.24900:01:16.259 it's a gas-fired turbine engine that 00:01:19.01000:01:19.020 drives the compressor and by process of 00:01:21.44000:01:21.450 burning the natural gas to create the 00:01:24.29000:01:24.300 power to turn the compressor the actual 00:01:26.63000:01:26.640 exhaust goes through an oxidation 00:01:28.82000:01:28.830 catalyst which further reduces the 00:01:30.95000:01:30.960 emissions to the fact when once you're 00:01:33.98000:01:33.990 if you're standing on a natural gas 00:01:35.63000:01:35.640 compressor station and you're looking at 00:01:37.19000:01:37.200 the exhaust you see no emissions there 00:01:39.35000:01:39.360 are no emissions that visible and a 00:01:41.87000:01:41.880 natural gas compressor station facility 00:01:43.96900:01:43.979 is operating at 100% capacity while 00:01:46.27900:01:46.289 we're standing here talking as you can 00:01:48.59000:01:48.600 see I'm talking in a normal tone of 00:01:50.84000:01:50.850 voice I'm not having to raise my voice 00:01:52.82000:01:52.830 the building is insulated with the 00:01:55.70000:01:55.710 exhaust itself is also covered with an 00:01:59.24000:01:59.250 insulation that basically mitigates the 00:02:02.02900:02:02.039 amount of noise coming from it the 00:02:03.80000:02:03.810 amount of noise that's that's at a 00:02:05.38900:02:05.399 compressor station outside the fence of 00:02:07.49000:02:07.500 a compressor station is really very 00:02:09.94900:02:09.959 similar to what you would have if you if 00:02:11.75000:02:11.760 you're in your residential plan standing 00:02:14.09000:02:14.100 in your front large yard and a car goes 00:02:15.92000:02:15.930 by I mean that's essentially the noise 00:02:17.56900:02:17.579 level that you're going to be hearing 00:02:24.19000:02:24.200 here at Dominion safety is our primary 00:02:27.05000:02:27.060 core value it everything we do is 00:02:29.53900:02:29.549 focused on safety the facilities are 00:02:31.94000:02:31.950 monitored on a 24/7 basis by our gas 00:02:34.55000:02:34.560 control operations in West Virginia we 00:02:37.58000:02:37.590 have people on site every day monitoring 00:02:40.28000:02:40.290 the facilities checking to make sure 00:02:42.61000:02:42.620 everything is working within the right 00:02:44.56900:02:44.579 parameters we do a lot of inspections to 00:02:47.53900:02:47.549 ensure that the the all the controls are 00:02:50.20900:02:50.219 in place and functioning properly we 00:02:52.39900:02:52.409 have what we call an emergency shutdown 00:02:54.83000:02:54.840 system at our compressor stations and 00:02:57.31900:02:57.329 what that does is it basically can shut 00:02:59.39000:02:59.400 the main the main valves coming in and 00:03:01.69900:03:01.709 out of the station such that the entire 00:03:03.92000:03:03.930 station can be isolated from the 00:03:05.53900:03:05.549 pipeline from our perspective the safety 00:03:07.97000:03:07.980 of our employees is paramount we want 00:03:10.06900:03:10.079 them to be able to go to come to work 00:03:12.37900:03:12.389 every day safe and go home every day 00:03:14.20900:03:14.219 safe not only that just themselves but 00:03:17.39000:03:17.400 their friends and family that live with 00:03:18.89000:03:18.900 them in the community as well the 00:03:20.75000:03:20.760 operation of a compressor station is 00:03:22.67000:03:22.680 really contingent upon the customer 00:03:25.03900:03:25.049 requirements at any given time typically 00:03:29.00000:03:29.010 in the winter there's a lot of natural 00:03:31.25000:03:31.260 gas required for a heating for the 00:03:32.86900:03:32.879 heating load so the natural gas 00:03:34.90900:03:34.919 compressor stations operate fairly 00:03:37.58000:03:37.590 frequently during the winter operations 00:03:39.42900:03:39.439 during the summer now with the advent of 00:03:42.22900:03:42.239 natural gas-fired power plants have a 00:03:44.27000:03:44.280 fairly significant cooling load required 00:03:46.72900:03:46.739 in the summer so we also run the 00:03:48.97900:03:48.989 facilities at some some higher frequency 00:03:51.61900:03:51.629 in the summer than we would in the 00:03:52.84900:03:52.859 follow the spring
