PCI is a registered provider of AIA-CES, but today's presentation does not contain content that has been endorsed by AIA. Today's presentation is non-CEU. Our presenter for today is Ted Leslie, Business Development at Midwest Industry Supply. I will now hand the controls over so we can begin our presentation. Thank you, Nicole. So, hi. First, I'd like to thank the PCI group for allowing Midwest to present today. Midwest is a PCI Premier Partner participating in the Safety and Environmental Committee, Associates Supplier Committee, Productivity Tours, PCI Convention of Pre-CASH Show, various regional and national events, Committee Days, and our next event will be at the PCI Central Region Summer Event at Belterra in Southern Indiana on August 23rd. Just a little bit about Midwest Industrial Supply. We're headquartered in Canton, Ohio. We have in-house soils laboratory and research and development facility, as well as an application center where we produce equipment specifically for the installation of our proprietary materials. We're a developer and manufacturer of innovative and eco-friendly soil stabilization, dust suppression, fines preservation, road management, anti-icing, de-icing, and rail lubrication products. We have satellites from California, Texas, Arizona, Illinois, Indiana, Michigan, Georgia, Canada, and have been in business over 45 years. Our specialization is really fugitive dust from unpaved surfaces. Our core markets outside of the pre-CASH industry include heavy industrial sites, steel mills, mining operations, constructions, and maintenance of gravel runways, soil stabilization, and municipal dust control. So to frame the conversation for today, specifically with fugitive dust at pre-CASH facilities, we're talking about emission source points of unpaved roadways, storage yards, parking lots, production areas, shipping areas. The equipment that runs through these facilities, very heavy equipment, articulating wheels, turning, twisting, constant traffic, large unpaved areas. We do get asked from time to time, especially in this industry, about concrete indoor surfaces. So we really don't do anything indoors unless it's an unpaved roadway, specifically to be treated as unpaved. So once again, as we talk a little bit about the problem statement, you can do a Google search for silica dust or just fugitive dust and the things that are coming about in today's day and age. We get traditionally industrial areas that used to be outside of town or traditional unpaved areas where urban sprawl, residential development, enforcement of fugitive dust migration beyond property lines were all kind of off the radar and now are more in the spotlight ever and ever. Not to mention greater understanding of the potential health risks. So as you see, some of the things you get into here, you know, concrete plants sited after neighborhood buried in dust, silica is the new asbestos, whether it's MSHA, OSHA, neighbors, counties, cities, states, there is increasing pressure on the control of fugitive dust, not just from an employee health and safety standpoint, a good neighbor standpoint, all of those kinds of things where we're now starting to find a massive connection linking all of these things together. And once again, if we start to try to pinpoint some of the costs of the problem that exists with fugitive dust, we're looking at productivity, general safety, employee health, retention and experience. Everyone in today's day and age is having a hard time retaining employees, especially if the working conditions are as brutal as they can be in the concrete industry. So we're looking to try and improve that employee experience and improve employee retention. There's an equipment life cycle and maintenance costs associated. Aggregate loss, maintenance for maintaining those roads. Depending on the part of the country that you're in, water conservation is becoming increasingly important. And we're going to talk a little bit about traditional dust suppression techniques and the use of water and where some of the pitfalls around water might be. You've got environmental compliance with permitting, permits to operate, Title V, Clean Air Act, National Ambient Air Quality Standards. We're also going to talk a little bit today about the OSHA silica rule compliance. And in general, it's just nuisance dust, good neighbor policy, community standing and public relations. The facilities, all the employees, their families, we want to be good stewards of the community in which we are operating and doing business in. Once again, just general overall environmental health and safety. So these are some of the factors that we really want to kind of pinpoint as we kind of frame the issue of fugitive dust and some of the traditional mechanisms of control and then some of the different types of technologies that Midwest Industrial Supply brings to the table. And once again, when we start talking about fugitive dust and particulate emissions, dust particles less than 10 microns in size that are respirable create a health hazard. And specifically, these are what the EPA is looking for in terms of serious heart and lung health effects that can be long term. And as an employer, as we start taking a look at as these as these materials are becoming more studied, more captured with different types of monitoring that's happening at property lines, we just need to become a little bit more aware of just really what the impact is, both from a operational productivity standpoint and the impact on the health and safety of the employees. And once again, we're starting to talk about things with inhalable coarse particles and fine particles. Very, very, very, very small. You know, how many PM 2.5 you're talking about, just fractions of a slice of a piece of a human hair. Very, very, very fine, respirable, inhalable dust that can become impactful with overall health. And why do we care about these things? Right? And you start talking about OSHA, silica rules, compliance with these kinds of things. And you start talking about 50 micrograms per cubic meter calculated over an eight hour work shift as far as the permissible exposure limit. And if you take a look at the slide right there, you're talking about that little speck of respirable silica that's sitting next to the penny there. And that would be, you know, at risk of an exceedance with that much inhalable over an eight hour shift. So we're really talking about really fine particulate, really kind of exposures that can cause long-term health issues. And once again, risk to operations. Crystalline silica is found typically in sand, soil, concrete, mortar, granite, and other minerals. Most common form of crystalline silica, however, hazardous levels can be emitted from the roadways as well. We've had some situations where we found background data of respirable silica where the testing and the monitoring can come up with the exposure limits. And really what we're looking to do is to try and how can we find a way to keep in compliance with these new initiatives and how can we keep our employees safe? And once again, here's a site photo that I took a couple of weeks ago. We're really, really, really at the phase right now where we can take the particulates out of the monitors. We can test them, we can sample them, we can find out what exactly it is. And it's more and more that respirable silica not being looked at just from coming off of a sawing or cutting or a blasting or those kinds of operations, but even what could be coming as far as background dust from fugitive emissions off of roadways. So we kind of start now to talk a little bit about traditional methods and how is fugitive dust controlled and what are the mechanisms of control. And once again, back to framing the issue, we've got large unpaved facilities, storage yards, shipping areas, all of those kinds of things. And some, because of the traffic in these facilities, the weight, the twisting, the turning, some options become more and less viable. So if you start and you talk about number one, reducing the quantity of silt and potential emissions from the roadway by removal. You can do this by paving. All of a sudden we're going to pave, we're going to remove anything that's particulate that could become airborne, sweep it, flush it, grade it off, add big slag, all those kinds of things. The problem comes with the transition of unpaved pave areas, as well as you place new aggregate. And once again, just like a mortar and a pestle that you're going to crush that stone up, you're going to crush that up and start that cycle of creating more potential emissions. You can increase the moisture content of the silt. You can have water, weigh it down. It's no longer become airborne. And this is done with watering, hygroscopic suppressants, things of that nature. And then you can also reduce the quantity of silt and potential emissions on the roadway with a conglomeration, finding agents, chemical suppression. And we'll talk a little bit more about that. And once again, there are some physical controls that you can put into place. We talk about this from a traffic pattern analysis standpoint, or an AP 42 standpoint of taking a look at all the variables that are in here, the speed of the traffic, and we slowed the equipment down, the weight of the equipment, the number of wheels, the number of vehicles, miles traveled, all those kinds of things. You can jersey barriers to control traffic flow and to really focus in on trying to eliminate some of the physical activities that are generating the fugitive dust. So here we go, the concrete business. It's always been a dusty business. What do you do? And people will do everything from, hey, it's probably no one on this call. Everybody understands you need to keep things going. But in general, we find a lot of plants watering viewed as a low cost solution. It consumes people, it consumes equipment. And we'll talk a little bit about some of the side effects of watering programs and the effectiveness of maybe what some of the hidden costs are, the price of fuel, the price of people, all of those kinds of things in terms of what you're getting out of the program. There are dust control, chemical suppressants and commodities and byproducts, engineered solutions. And it can be a little bit confusing. We'll talk a little bit about that as well. You take a look at the price per gallon, the chemistries that vary all the way across the board, potential downsides, are some of the products going to be corrosive? Do they have an impact on the finished goods of their groundwater? Do they maybe create another problem down the road? And one of the things that we like to talk about are dust control programs and a site strategy developed specific for the site. And it can be very, very simple, they're very, very complex. Trying to look at it as far as becoming outcome-based, a predictable control efficiency. And then there's just some options around doing those service program to a guided self-applied program where you're doing the dust suppression yourself. And that's always one of my favorite pictures that I put up there from a site of a old rusty water truck that sits out there. And I know a lot of people have, you know, the watering program kind of becomes one of those necessary evils. And sometimes there's, it's a very important topic as far as fugitive dust, but it gets lost in the wash in terms of the value that it can provide. But when you start putting in to perspective, the risk that is there from that environmental health and safety standpoint, it's one of those areas where a lot of plants are really looking for ways to improve the effectiveness of what they're doing and really evaluate what the costs are associated with the current practices. So the way we'll talk a little bit about watering and the traditional solution is that it's kind of a strategy that provides very temporary dust control. The control efficiencies go from almost zero, very, very dusty to, okay, so there's no dust, it's wet, and it goes back and forth in timespans of anywhere from 15 minutes to an hour, depending on the part of the country that you're in. So it's basically just kind of a nonstop cycle where you get control levels that go from very, very low to very, very high rapidly throughout the day in terms of what kind of a control efficiency that you're getting. And then once again, some of the things that happen there as far as degrading the road, washing out, loss of fines, potholes, washboarding, maintenance costs, regrading, not to mention some other things that we'll get into as well as far as some of the other costs in terms of even sweeping up on paved areas and I had a site and we'll get into that in just a minute as far as you know what is watering really cost and we talk about it as the negative cycle of watering just in terms of how you go from the water to the fines the potholes to the grading to the aggregate and then just creating that muddy environment. I just recently had a customer scenario where there was ten to fifteen thousand dollars a month with an outside contractor not on the watering but on the sweeping of the paved roads leading in and out of the facility and it was really not even enough they were sweeping once a day it was about twenty five hundred dollars a day to sweep but constantly mud just going into the buildings into the maintenance areas into the offices and once again onto the public streets to where they're trying to take care of a one issue just kind of an example where you try and solve a problem here and you end up costing causing another problem and another expense down the road and here's an example of a stationary motion camera that that we had from a site where and this is a haul road where once again you can see a picture tells a thousand stories once again after 15 minutes after 30 minutes after 60 minutes after 90 minutes you know what you're really seeing from pass to pass in between from a water truck it's just kind of a nice visual observation there and then below there's a chemical suppressant application once again we'll start talking a little bit about the idea that we're looking at taking control efficiencies in time lapses and we're trying to move them from minutes and varying degrees to days weeks even months and to keep that control efficiency at a very tight level we'll talk about dust control down to a science in the toolbox some of the things that are disposal that will utilize when working with the site everything from just a qualitative evaluation of dust emissions visual surface assessments visual emissions observations and then go on from different types of things where there there may be a stationary dust monitor on-site that we can we can work with silt load testing to measure pre and post application levels of potential emissions stationary motion cameras all of these kinds of things that we've got in our toolbox that we've used in developing our programs or we can even work with a specific site to develop an emission road emission reduction program and strategy to to really make sure that we're gonna we're gonna get all the information we're gonna quantify what we need to do and we're gonna deliver the results that we're looking to deliver we came out with an e-book a few years back and it was if you tried dust control and it failed here's why there are some common there are some common myths that we believe exist in the industry as far as you know why does it why does chemical suppression fail at some places why does it not fail at other places even why does your watering program work better or worse than it could and what are the things that could be done so these are just some of the types of things that we've put together over the years and if anybody's interested in some of our ebooks we have an amazing library of information on our website ebooks case studies testing independent testing on different situations to really go to the depth of what our dust control down to a science has kind of taught us over 45 years in the business you basically when it when it comes down to it we kind of have these beliefs about dust control in terms of evaluating the site and understanding the sources the challenges and the emissions and once again dealing with dealing with the the precast concrete industry in general it's one of the most brutal aggressive situations in terms of trying to control dust that you can find and that's dealing even dealing with mining operations dealing with steel operations quarry operations the things that are happening inside of a precast concrete site just the constant movement the raw materials that you're using and bringing in what areas dry areas all of those kinds of things so so there are a lot of challenges that need to be addressed as far as putting together a program to tackle a specific problem or a specific pain point critical knowledge needs to be accumulated to understand the traffic flows and the track on the contamination sources and that the products are only really a part of the solution a big portion of it is the application strategy technique planning chemistry all the different types of attributes to really make us come up with a site-specific program based on the the goals of the facility and really what the pain points are that you're trying to get addressed we call it our Midwest proven process trying to take a look at understanding the facility and really the goal of what we try to find out at every facility is to establish an ongoing work practice standard that sufficiently mitigates the fugitive dust emissions and utilizes the least amount of dust suppressing chemical possible understanding the acceptable level of fugitive dust and balancing them with budget so we'll go through this diagnostic process diagnose design deliver and then try to review and come up with continuous improvement coming up with continual recommendations to try and make sure that we can find that that that sweet spot and to make sure that we get that that happy long-term client we're looking to find as far as a as far as a partner some of the elements that we really want to make sure is that we understand all the you know there's going to be an accountable department or a person but really who all the stakeholders are and it could really even be people inside the shop not just in the in the mobile equipment area the shipping area the storage area but really putting the stakeholders together to understand maybe what some of the pain points really are trying to establish goals mapping the areas and identifying the activities by area in the control measures that are used document results and learning once again all at the end to come up with continuous improvement and come up with a work practice standard that's going to meet the goals of the facility and once again it may not be that the chemical suppression plan is the proper rub to go at every part of the facility there may be places where water is the right thing there may be places where a couple of different chemistries might need to be employed in the facility and really that's that's what we're trying to come up with is a is a is an all-encompassing plan and a work practice standard that's going to deliver a predictable repeatable result once again site information in mapping site planning the first step that we want to get into what are the pain points we might find that around the building in and out of the out of the plant the entry road mobile equipment bay doors those kinds of things there might be an employee parking area there might be a break area where there's a picnic table that you're finding that we may need we may not need to profile 50 acres the facility maybe we profile five acres or ten acres you know with some of the different planes that we've developed we can really kind of customize what the pain points are and how we can try and best come up with the solution and program design we'll talk a little bit more about program here in a little bit but the bottom line is that we're trying to come up with a strategy that's going to work over time because of the nature of the facilities that you're running the idea that a chemical suppression application is a plan or a program with the type of activities that are happening we've basically found that you really do need to kind of hit those trouble areas hit those trouble spots and and identify what needs to be done and it isn't it's been one of the largest learnings that we've had over the years is that an application of a chemical in this environment generally doesn't work we need to look at it as a plan day one day 15 day 30 day 90 and we may find that over the 90 days that we've gotten started at the facility that we can evaluate things and we may find that a portion of the facility can have an application or two or three but some of the problem areas are going to probably need to be dressed every 30 days or so more or less but there there can be and that's why it's so important to kind of identify the the activity the soil type and really what's happening in the different areas of the facility so once again we're really looking to coming up with it with an action plan and as I kind of alluded to before if you looked at the chart about water what we're really looking to do is tighten the variance of the control efficiency and we're starting to talk about changing the bottom line of the equation from minutes of control to days or weeks or months of control and what you find from here is that hopefully we can depending on the the goal of the site come up with a strategy to where there's not a water truck commingling with shipping activities production activities all of those kinds of things creating some of the other hazards and risks around it that you're looking to to to control the dust and what kind of activities are getting in the way so that's really what we're trying to look at with an emission reduction plan is how to tighten that gap that gap between control efficiency and days of control from a chemistry standpoint we have a product called EnviroClean it's a material that we've developed it's been tested from both the performance aspect and environmental aspect by some of the most stringent agencies from the environmental technology verification the FHA to the USGS we've had extensive work and studies done on the material it's about as environmentally sensitive as as anything that you could find it's very very easy to use it's really the ideal material for the precast concrete industry when you start talking about fugitive dust and you start talking about what the options are for mechanisms of control it's very understandable why water was the solution that was landed on most of the commodity dust control products that are on the market today have some downsides for your industry the industry that's working with rebar inside of the concrete that's looking at spalling corrosive activities that you don't really want to have those materials on your property there's some other materials that are are dark in color whether it's a co-product or a byproduct of a petroleum resin to an asphalt to a tree pitch sap material once again creating potential for impact on your finished goods so the EnviroClean product is really what we've landed on as being the ideal product for your situation and once again has some other things about it it requires no water for dilution so areas with issues with water conservation you don't have to worry about taking plant water or even city water if you had to I ran across a situation where it was a municipal water source that was being used for watering and the water bills were astounding so where we where we land on the chemistry side here our EnviroClean product is something that's been really in my mind ideal for this for this application and then from there we talked a little bit about application strategy and we've got a few different strategies that we talked about we do have men and machines and equipment through our satellite system throughout the country where we have larger scale application equipment to come can come out and do applications for you we also with our application center have designed a piece of equipment that can turn a pickup truck or a flatbed or a trailer or even we've had forklifts turned into the application equipment because the EnviroClean requires no water you don't necessarily need giant tanks you can use it with a simple spray system that can go onto the piece of any of equipment to really make it to where you can pinpoint and and identify problem areas in your plant and address some kind of on-demand and along the way we do have our virtual management shell where we can help you with training and tools and technical support to properly manage the dust at your facility utilizing your own equipment and personnel so to kind of round out the story here as far as framing what we've got you know we've got a we've got a an increase extremely aggressive environment we've got increasing regulatory pressures coming from cities states counties OSHA I'm sure all those kinds of agencies that are going to be around and an ideal situation here with Midwest providing system and process driven emission reduction strategies dust control down to a science to deliver predictable and consistent results with product selection application strategy application plan and a partner for compliance based dust control with continued continuous improvement and long-term success and at the end of the day really adding a powerful tool to the toolbox it may not be able to solve all of the issues at a site we can really make a significant impact by targeting pain points where current practices potentially are underperforming oh perfect at this point Nicole I'll open it up to questions if anybody has any questions wonderful Thank You Ted for a great and informative presentation I haven't seen any questions come through yet so I'll give it about 10 15 seconds to see if one does come through perfect and I apologize if I blew through anything too quickly if anybody would like me to go back to any specific slides to come up with questions or once again if anybody's been out there and thinks of anything the the handout material will be available and you told me Nicole in the in the Learning Center it's able to be listened to or shared again if anybody does come up with any questions you can find us at Midwest IND comm or Ted Leslie Ted Leslie at Midwest IND comm as well perfect thank you um I've not seen a question or two come through so on behalf of PCI I'd like to thank you for a great presentation if anyone has any further questions about today's webinar you can either email marketing at PCI org or you can contact Ted Leslie with his email that's currently on the screen thank you all again have a great day and stay safe
