1. Introduction to B&T Extra and Greg Warren

Christopher:
[01:15] "It's another Bob and Tom Extra. This is Christopher. Not only is the Bob and Tom show live every weekday morning, but every afternoon we'll give you a little extra. In case you missed anything on today's big show, Greg Warren with the Warren Report today on Road Salt. It's coming up in just a minute."

Chick Magee:
[04:03] "Greg Warren: We have a guest. I think we're gonna hook up with Greg Warren."

The segment kicks off with Christopher introducing "B&T Extra," highlighting that this afternoon edition brings additional content from the main morning show. Greg Warren is introduced as the guest to present his report on road salt, setting the stage for an in-depth discussion.

2. Road Salt Overview and Importance

Greg Warren:
[07:38] "Yeah, I thought it was time that we took a hard look at road salt, Tom."

Bob initiates the core topic by emphasizing the need to examine road salt closely. The discussion covers the fundamental role road salt plays in maintaining road safety during winter by preventing ice formation and ensuring vehicles can navigate slippery conditions.

3. Types of Road Salt

Greg Warren:
[07:44] "Can you eat rolled salt, Greg?"

Bob:
[07:46] "Well, you know, it's interesting you say that, Josh, because the common road salt out there is sodium chloride, which is basically the same as table salt. The difference is table salt is ground down more. The salt out there is called rock salt. It's a, you know, a chunkier version of sodium chloride."

Greg elaborates on the different types of salt used for road de-icing:

• Sodium Chloride (Rock Salt): Commonly used due to its effectiveness in melting ice.
• Table Salt: Finely ground and often iodized to prevent goiters, containing anti-clumping agents.
• Calcium Chloride: Effective at lower temperatures but more costly and harmful to flora and fauna.
• Magnesium Chloride and Potassium Chloride: Alternatives with varying properties and environmental impacts.

Bob:
[10:22] "I just go ahead and say, do you guys know where the, the salt comes from?"

The hosts delve into the sources of road salt, discussing its extraction from salt mines—large underground facilities where salt is harvested.

4. Salt Mines: Locations and History

Bob:
[10:32] "It's really a Good question. In the US There's a big one in Cleveland, New York State, Kansas, Louisiana, I believe you were talking about. There is one under Detroit. And when I say under Detroit, I don't mean Toledo. I mean underground of Detroit. It's huge. It's a hundred miles of tunnels and. And it's 1200ft below the city."

Greg Warren:
[12:00] "Wow."

The conversation highlights major salt mine locations across the United States, including Cleveland, New York State, Kansas, Louisiana, and notably, a massive salt mine beneath Detroit. These mines have been operational since the late 19th century, with one such mine discovered in 1895, utilizing donkeys for transportation within the tunnels—an anecdote that adds historical context and humor to the discussion.

Bob:
[12:05] "That thing opened. It was discovered in 1895, and they were. They used donkeys to haul the salt. They would lower the donkeys in, and apparently the donkeys never came out after that. Oh, it's just kind of sad. Sad existence."

5. Environmental Impact of Road Salt

Bob:
[15:07] "There's different kinds of salt out there. Like I said, sodium chloride is the. The most common. There is a magnesium chloride that works at lower temperatures than sodium chloride. It's a little harmful to the fauna and the. The flora."

Road salt's environmental repercussions are significant:

• Water Supply Contamination: Runoff from road salt can infiltrate water sources, making drinking water saltier and affecting aquatic ecosystems.
• Corrosion: Salt accelerates the corrosion of metals, impacting vehicles, infrastructure, and steel buildings.
• Soil and Plant Damage: Excessive salt can harm plant life, disrupting soil quality and damaging vegetation.
• Wildlife: Animals, including moose and other large fauna, may seek out road salt as a mineral supplement, leading to unintended ecological interactions.

Bob:
[17:18] "There are some alternatives, guys, that you can. If you add beet juice or cheese brine to the salt, it sticks to the road more. And you don't have to use quite as much salt, but you run over a."

Chick Magee:
[17:22] "Lot of animals munching on the cheese."

Greg mentions alternative solutions, such as mixing beet juice or cheese brine with salt to enhance adhesion to the road surface, thereby reducing the total amount of salt needed and mitigating environmental impact.

6. Economic and Structural Damage Caused by Road Salt

Bob:
[16:45] "I think you might be on to something, Tom. Yeah. These things do about $5 billion a year in damage to trucks, roads, and bridges."

The hosts discuss the staggering economic cost of road salt, estimated at around $5 billion annually in damage to infrastructure and vehicles. The corrosion caused by salt deteriorates road surfaces, bridges, and vehicles, leading to increased maintenance costs and reduced lifespan of these assets.

Greg Warren:
[17:10] "Yeah. It is interesting because they. They say they reduce accidents by 87%, so that's major."

Despite its drawbacks, road salt plays a crucial role in enhancing road safety by significantly reducing the number of winter-related accidents.

7. Alternatives and Improvements to Road Salt Usage

Bob:
[18:10] "There are some alternatives, guys, that you can. If you add beet juice or cheese brine to the salt, it sticks to the road more. And you don't have to use quite as much salt, but you run over a."

The discussion explores potential alternatives and improvements to traditional road salt usage:

• Beet Juice and Cheese Brine Additives: These can increase the stickiness of salt on roads, reducing the total quantity needed.
• Magnesium and Calcium Chloride: More effective at lower temperatures but come with higher costs and environmental concerns.
• Potassium Chloride: Another alternative with different efficacy and environmental profiles.

The hosts humorously speculate about the practical implications of these alternatives, such as increased wildlife interactions with cheese brine on the roads.

Bob:
[15:53] "And then there's a potassium chloride. All this stuff, guys, for the most part, it's. It's got some. It does some bad stuff. It corrodes the metals on your car. It corrodes the rebar in the. In the road and even steel buildings. Salt does a ton of damage."

Chick Magee:
[19:13] "There are 10 times as much salt on the roads as there is in processed food."

This statistic underscores the vast quantity of salt used in road maintenance compared to dietary intake, highlighting the scale of its environmental footprint.

8. Concluding Remarks and Future Outlook

Greg Warren:
Greg wraps up the report by emphasizing the balance between the necessity of road salt for safety and its adverse effects on the environment and infrastructure. He encourages ongoing research into more sustainable and less damaging de-icing solutions.

Tom:
[17:19] "Yeah. There's also quite a bit of environmental damage that comes from the salt. It messes with the. It gets a lot of people's waters supply gets salt in it. During the winter, a lot of drinking water tastes saltier."

The hosts conclude with a reflection on the complexities of road salt usage, acknowledging its indispensable role in public safety while advocating for responsible and innovative approaches to mitigate its negative impacts.
