S.B. 146 Industrial Byproduct Amendments

What this bill does

The bill would allow municipalities, not just the Utah Department of Transportation, to use approved industrial byproducts such as steel slag, including the remaining slag pile at the former Geneva Steel site, in city projects like sidewalks, curbs, gutters, and parking lots as aggregate base. Use would require approval from the director of the Division of Waste Management.

     Senate bill 1 46. Senator Grover for brief presentations.

  2. Sen. Keith Grover0:31

     Thank you, Mr. Chair Committee. I, I, uh, live in Utah County, and I represent, um, what used to be the former site of Geneva Steel, which is now the City of Vineyard, and also become what's known as Utah City. And out there, the, there's still some remains of the old Geneva site, uh, much of which is a large slag pile, and that slag pile's been used for industrial purposes. And we just wanted to, with this bill, uh, broaden that just a little bit so, uh, other entities could use that. And I have with me, uh, Mr. Rob Jolly kinda explain a little bit more in detail.

  3. Rob Jolley, lobbyist, Flagship Homes1:07

     Thank you. It's a pleasure to be here with you today. Yeah. My name is Rob Jolly. Hold That microphone closer, sir. I'm lobbyist for Flagship Homes who now owns the Geneva Steel site. Um, Senator Harper may remember about 10 years ago, we passed legislation dealing with this, the same, uh, industrial BI-product material to allow it to be used, uh, by udot for road base. And, um, now we have a situation where, uh, Vineyard City, um, and also what's called Utah City, uh, would like to use the same material for road base and other areas that will be, that will have a hard cap. Um, and this is a material that the director has to approve of to be used. And so all this bill really does is expand its use to, um, to cities and counties if they so desire to use it. Um, you know, we've met with DDEQ. We're gonna continue to meet with DEQ. We didn't have time to get amendments ready for today, but, uh, I expect that on the floor of the Senate, we'll have some amendments that, that, uh, we've worked with DEQ on. But, uh, that's pretty much all the bill does.

  1. Rep. Calvin Roberts (Committee chair)1:34:06

     Thank you, Senator. Okay, we'll move to the next item on our agenda. Um, SB 1 46, the first substitute by Senator Grover.

  2. Sen. Keith Grover1:34:16

     Yes, thank you. Committee. Uh, this bill is pertains to the slag pile down in what used to be the old Geneva steel site. It's currently, well half of it's now, what is now Vineyard. Have, you've been down there lately. It's no longer a steel site. And so there's still, uh, extensive slag pile that for years has been used for road base. Udot has used that, and it's been great. And so this bill allows municipalities to also use that slag pile, and it's, we needed to actually pass legislation to make that happen. So that's what this bill does, and so they can use it in other for municipalities.

  3. Rep. Calvin Roberts (Committee chair)1:34:47

     Great. Does that conclude your presentation? It does. Okay. We'll come to the committee now for any clarifying questions. I have one. I've got one. Oh, yeah, I'm, uh, Yep. Chair Christofferson.

  4. Rep. Kay J. Christofferson1:35:01

     Thanks. Uh, so in, in the business I was involved in for years, we used that stack pile, uh, and we bought it from an engineering company that would, would, um, um, crush it and grade it and make it into road base or other products. So I'm just wondering why we need authorization for cities to use that. Uh, that was a private use, I assume, correct. Right.

  5. Sen. Keith Grover1:35:32

     Right. And so this, this was very regulated just to udot using it, and the, and the municipalities cannot access it, but private could. So

  6. Rep. Kay J. Christofferson1:35:40

     Is it still owned by a private company?

  7. Sen. Keith Grover1:35:42

     Uh, the slag, yeah. Whatever is remaining of the Geneva Seal site. Yes. I don't know if it's Anderson, Geneva, or Exactly. Who owns that? Yeah,

  8. Rep. Kay J. Christofferson1:35:49

     I, I guess I don't understand because they sold it to who, whoever they sold it to udot. We, we used it as a company and we did work on Udot roads, and we did work on city roads, and we did work on private stuff, and we used that forever. So I'm,

  9. Sen. Keith Grover1:36:03

     Yeah, it's my understanding without

  10. Rep. Kay J. Christofferson1:36:05

      This bill, I'm okay that they use it. I just don't understand why we have to Yeah,

  11. Sen. Keith Grover1:36:09

      My understand. Without the bill, they cannot use it like the way that they'd like to, so,

  12. Rep. Kay J. Christofferson1:36:16

      Okay. Go ahead, chair. Sorry.

  13. Rep. Calvin Roberts1:36:20

      So who's asking you to run the bill?

  14. Sen. Keith Grover1:36:22

      Uh, there's different, uh, different groups are asking it. Vineyard City wanting to use some of the flag pile and other municipalities wanting to use it. So,

  15. Rep. Calvin Roberts1:36:31

      So that they have to pay the private company for it?

  16. Sen. Keith Grover1:36:34

      I would assume so, correct? Yes.

  17. Rep. Kay J. Christofferson1:36:37speaker not certain

      So, uh, I really is struggling with this because why would they have to, why would we have to authorize a private company to sell to a city when they've been doing that for years and years?

  18. Sen. Keith Grover1:36:48

      That's, that's just my understanding. They can't do it.

  19. Rep. Calvin Roberts (Committee chair)1:36:54

      Okay. Uh, we'll go to Representative Chevre with questions.

  20. Rep. Kristen Chevrier1:36:58

      I think it already got asked. Thank

  21. Rep. Calvin Roberts (Committee chair)1:37:00

      You. Okay. Any other clarifying questions from the committee? Okay. We'll go to the public for any comment. Is there anybody from the public who wants to comment on this? Bill? Anybody online? Okay. We're gonna close the public comment portion, um, and come back to the committee for any action. Representative Christofferson.

  1. Speaker (presiding)27:12

     Back to you Representative Bollinger for presentation.

  2. Rep. Bridger Bolinder27:15

     Thank you, Mr. Speaker. So this bill provides that an industrial byproduct, for example, in the still making process, a slag product may be used in a project if it is approved by the director of the Division of Waste Management. So I'll give you an example. So we have some steel manufacturers in our state that produce a slag product through the, the manufacturing process. This is normally a waste product. And so this bill allows that material to be used in projects for cities if it is approved by the, the division to be used for that. So an example of projects would be sidewalk, curb and gutter parking lots, and it would act as like an aggregate base course in those instances. So with that, I'll take any questions.

  3. Speaker (presiding)28:01

     Thank you Representative Bolinder discussion to the bill. Representative Voxer

  4. Rep. Tracy Auxier28:09

     Yield to a question.

  5. Speaker (presiding)28:11

     Representative Boer, will you yield to a question?

  6. Rep. Bridger Bolinder28:14

     Absolutely, Yes. Representative Voxer. Thank

  7. Rep. Tiara Auxier28:16

     You. I was just wondering if these byproducts haven't been able to use be used in the past? Why not? And then why now do we want them to be?

  8. Rep. Bridger Bolinder28:25

     Yeah, good question. Thank you, Mr. Speaker. So in the past we haven't been able to use them with some environmental concerns. Maybe these products have, uh, some leaching characteristics or anything like that. What the purpose is, is it should actually save money on city projects because aggregate can be expensive. Um, myself better than anyone knows that. And so I think this is a good way to recycle materials. We do this with asphalt wraps and other materials in construction projects.

  9. Speaker (presiding)28:57

     Okay. A follow up if you, Mr. We yield to a follow up question. Yes. Representative Auxier.

  10. Rep. Tiara Auxier29:02

      Um, I'm just wondering about the leaching process and you know, if we're gonna be putting these in sidewalks and other things, will there be any sort of guidelines around what products or chemicals would be leaching into our grounds?

  11. Rep. Bridger Bolinder29:20

      Yeah, that's, that is, thank you Mr. Speaker. So that is why the director of the Division of Waste Management has to approve this to make sure that this is safe to use in, in those projects. Okay.

  12. Rep. Tiara Auxier29:30

      Thank you Mr. Speaker. Thank you,

  13. Speaker (presiding)29:32

      representative Boxier further discussion to the bill Representative Christofferson.

  14. Rep. Kay J. Christofferson29:37

      Yeah, thank you Mr. Speaker. Uh, I know that, uh, this product has been used for years and years and years, uh, probably over 50 years that I know of. And, uh, it's been used in, uh, soil stabilization, road base asphalt, uh, it's been used in all over Utah County and South Salt Lake County that I know of, uh, with no side effects, real effects. And I, I was kinda surprised that this bill had to come forward. But if there's any questions, uh, I think this is a good way to clarify that. So I support the bill.

  15. Speaker (presiding)30:20

      Thank you Representative Christofferson. Further discussion to the bill. See none back to you, Representative Bolinder for summation.

  16. Rep. Bridger Bolinder30:28

      Yeah. Thank you, Mr. Speaker. So, just to be clear, so this has to be approved by the director and these products to, to, to the point of the good representative from Utah County. They've been used in our state for, for a lot of years. And this will actually save a lot of, uh, costs for our cities on different projects if it, if it makes sense. So I appreciate your support.
