[speaker001:] well here in Logan Utah we got a nice little valley here and it's like crystal clear all the time except for during the winter when the inversion sets in and then we get a little bit of pollution in the valley
[speaker002:] hm well here in Seattle uh it's giving the air's getting more and more polluted to where uh we're in kind of a basin and uh  Seattle's on Puget Sound which is a inland waterway between two mountains and uh there's been a lot of lot of growth population growth around here and uh it's uh it's getting worse I think most of it is from cars
[speaker001:] yeah yeah definitely here in Utah up along the Wasatch front along the western side of the of these Rocky Mountains here where a lot of the big cities are Salt Lake and Ogden and Provo and Logan's up in the valley a little bit further north we get a lot of pollution and it's like seventy percent of it's from cars
[speaker002:] um-hum
[speaker001:] and uh it always really hits hard during the winter when we get the inversion and when we get get cold air down in the valleys and warm air up above and it just sits and sits and sits and we're starting to hit pollution levels now on the Wasatch front which match that of LA a few years ago
[speaker002:] uh-oh
[speaker001:] it's not it's almost sad because when I grew up here it was just always the crisp air up in the mountain valleys and now it's not in the mountain valleys
[speaker002:] yeah yeah I live in the university district and uh uh it's supposed to have about the worst air pollution I think probably due to uh a lot of students going back and forth to school
[speaker001:] huh
[speaker002:] and I'm we're right next to Interstate 5 also
[speaker001:] they're getting serious about things like uh mandatory well they've already passed laws where you have to get your cars checked for pollution if you're in certain counties emissions
[speaker002:] oh yeah oh yeah they started doing that yet
[speaker001:] yeah they've actually started doing it down along the not in Logan up here because we're doing a lot better we have a lot population's a lot lighter up here
[speaker002:] we have that here and uh they're they're expanding it to uh more counties here um as the population spreads out and I think they're also gonna be making it uh mandatory for more cars there there was uh something in the law about if you're car was over a certain age like over twenty years old you didn't have to get it done anymore and I think they're eliminating that uh
[speaker001:] yeah yep they're getting eliminating that out here
[speaker002:] that loophole yeah
[speaker001:] they're also talking very seriously about the thing called a dirt gun where they're uh looking at the emissions from the car using basically a spectrometer and looking at the basically how much of what is coming out the exhaust kind of like a radar gun and yes
[speaker002:] oh really they make you do that remotely
[speaker001:] yeah do it remotely just looking at the what they do they do several different types of things sometimes they put a source light and they look at the source light and then as the car goes by you can see the exhaust pipe and the source light behind it and you can look at the emissions actually
[speaker002:] hm now where does the source light go
[speaker001:] and like across the street they'll set up like a trap or something that add in some sense and they're also looking at uh
[speaker002:] oh I see
[speaker001:] other you know ways of monitoring this and because they found out something basically that uh and a poorly tuned car can emit something it's an incredible amount it was like four hundred times as much
[speaker002:] jeez
[speaker001:] um of certain pollutants and it was like unburned hydrocarbons then a a properly tuned car and and the idea being that if you just tuned up all the cars well if you tuned up this ten percent of the cars that were producing like fifty percent of the the pollution then you know you'd it be one way to cut the pollution in half
[speaker002:] yeah that's neat  but it's also been uh oh you know everybody is talking about using more mass transient here but it uh it's tough you know like I've I've looked into riding the bus to work and I can drive to work in uh and get there in twenty to twenty five minutes over a very congested corridor which goes over Lake Washington on one of the floating bridges
[speaker001:] uh-huh
[speaker002:] but if I uh  if I take the bus it requires several transfers and it takes over an hour
[speaker001:] um yeah and they're
[speaker002:] so it it's it's not hard to see why I why I keep driving and you know I feel guilty because I'm driving a
