Webinar: Managing Difficult Containment Penetration Method

Topic: BCI Webinar – Managing Difficult Containment Penetration Method Requested by: Lradcliff Date: October 28, 2021 Dan/Moderator: Alright, everybody looks like we've got the majority of the group coming in. And we'll probably receive a few more folks coming in, but we'll go ahead and get started. Good morning, and thanks for joining the BCI webinar series. My name is Dan Gray. I'm the Director of Sales for BCI. We'll be moderating today. And today's topic for our webinar series is “Difficult Penetrations and Secondary Containment Areas”. So, today we're going to discuss methods for sealing and working around difficult penetrations on secondary containment areas and systems. Some examples of things that we've seen that we've helped clients overcome are in their secondary containment areas are: • Piping passing through containment walls and areas • Grounding cables and substations • Pipe racks • Support structures • Roadways and walk paths • Drainage system components • Roofing penetrations and internal tank • Penetrations and components. So those are a few of the items that we've supported our customers with in the past. And today, Pete is going to speak to some of the proprietary and patented processes that BCI has to offer, that would be replacements or alternatives to traditional methods like batten bar and booting, which our customers have found are difficult or time consuming, their after leak despite best efforts, and they can require ongoing maintenance. So, we have solutions to overcome those types of issues that people have had. During the presentation today, as we go through the presentation, we definitely encourage questions. As the moderator, I'm going to be watching the chat and the questions through the webinar system here. We encourage you to type those in and then when I find a gap, I'll speak up and propose the question to Pete. And then if you feel more comfortable verbalizing your question, we're happy to open up all of the for public comments here after we get through with the presentation. But just for keeping everything, all the background noise and everything like that, we'll leave everybody on mute as we go through the presentation here. So, with that, I'm going to introduce Pete and then turn over the presentation to him. Pete Van Fossen has over 20 years of experience with specialty spray coating systems for secondary containment. He's the founder of Industrial Maintenance Group (IMG). IMG was purchased by BCI back in 2018, and it has been incorporated into our engineered secondary containment vision, which is BCI. And with that, I will turn it over to Pete and he can begin his presentation. Thank you. Who We Are Pete Van Fossen: Thank you, Dan. Good morning, everyone. So, I want to do a little kind of like housekeeping like Dan did and kind of talk about who we are. You're going to be hearing a lot about some of the industrial coatings that we've used over the last 20 years and how we apply them. But basic concepts had purchased industrial age group and put us under the Justrite safety group, as Dan said, some of the specialties of BCI concepts engineered solutions kind of varies, and it's all focused around secondary containment. Secondary Containment/Spill Containment/Drainage Solutions As you can see, in these photos here, we do everything from transformer containment to temporary or movable, portable containment for applications such as this fuel truck in the center here, to water management systems to where we can actually pump water out of a containment area and if oil hits it, it would obviously stop and seal and prevent any spill or leak from discharging from the containment area. And then the far picture is kind of just an example of coating over concrete, what we're going to see a lot of today where we prevent any cracks or leaking from containment areas. So those are some of the specialty items that BCI does; BCI Solutions Division actually does. Qualifications Highly skilled and experienced crews Self-contained spray equipment OSHA 10 – 30 Approved Confirmed space trained Hazmat/Hazwoper 40 trained ISNetworld Member/Approved First Aid and CPR trained On the coating side, we're going to get a lot more direct and focused on those items. One thing that we do like to talk about is highly trained, qualified crews will be on your sites. You'll have OSHA 10 to OSHA 30. All of our supervisors have OSHA 30. All of our workers OSHA 10. We have several confined space trained employees if not all the people on your site would be confined space and has Hazwoper and Hazmat trained as well. Some of the key things for people in our industry is ISN Networld, Aveda, I believe that when it's just sold out, but we are actually part of a lot of those networks, which makes it easy for clients to basically issue work orders and go to work type projects. Solving Difficult Fuel Penetrations So, with all that said, I will talk a little bit about the difficult penetrations that we see. As you can see in these first three photos here, you've probably seen some of these photos before if you've seen some of our other webinars, but I'm going to kind of go into more detail on what is actually occurring in those photos. So as a brief quick overview, basically fuel containment areas, as you see in the far left is, there are numerous different types of penetrations and challenges within those containment areas. The center picture here is basically a pond with the steel corrugated wall, where you have to make that transition but get have a watertight seal. And then the far one not necessarily always viewed as a fuel penetration is something like a geodesic dome, where you're trying to prevent infiltration into your fuel system. So, we're going to kind of go through a lot of these types of solutions and how we solve those. SC3900 and CR3000 FDEP approved Coatings • Sc – Structural Ceiling o 3900++psi tensile /300% elongation • CR – Chemical Resistant o 3000 psi tensile /100% elongation • Tack-free in seconds • 100% solids VOC free • Applies from 40-1000 mils dft • 20++ year expectancy • NSF approved and FC Contact • Highly abrasion-resistant • Tensile strength 3700-5500 psi • Inert to high UV exposure • Application temperatures: -40 to 300 This is our core products here are SC 3900 In our CR 3000. They are approved by most environmental agencies from New York, Florida to California, for use within containment areas. We use them in full containment as well as just sealing penetrations, as we're speaking about today, a lot of what you'll see is a is based around a full containment, but it's addressing the penetrations as we go through it. So, the SC 3900 is our structural coating SC stands for structural, it's over 3900 psi, it's got 300% along negation. So, what makes these coatings so applicable to these solutions is the elongation and the tensile strength. Most of the time we're spraying to concrete or some type of support that's moving, so the elongation allows us to move and flex with the penetration and be able to sustain and have longevity and its life expectancy. The CR 3000, which we'll talk a little bit about is our chemical resistant, very similar in nature 3000 psi tensile strength with 100% elongations. Again, has the elongation, typically greater than the structure that it's applied to, so it actually can move and flex with all the movement that you see within a current operation, or whether freeze thaw; those types of events. The good thing about both of these coatings is they're tack-free in seconds, so you typically can walk on them and less than a few minutes. They're 100% solid, so there's no volatile organic compounds. So, there's not a lot of need for moving people out of the area or stopping normal traditional workflow and working around where we're doing work. There's a 20 year plus life expectancy, we can apply virtually almost in any thickness 40 to 10,000, really virtually mills depending on the application, there's some processes that we would have to do in that situation. But we can apply in almost virtually any thickness. Both coatings are very, very highly abrasion resistance. If you have a wear area or being whether it's driving or water flow of water or flow of debris or flow of grit, or some type of material that would wear through these products were very well. We have NSF approved, which probably won't apply to most people and food contact approved. And then we actually have some additional coatings that we can get up to 5500 psi or some which is consider SC 5500. In an extreme condition, we use those products. They're inert to UV. One thing I do want to note is people don't realize sometimes UV will discolor and chalk up a coating. But it does not structurally damaging to the coating, the coating still maintains its structural nature. And then we can actually apply and withstand temperatures of negative 40 up to 300 degrees in operation. So, it's got a wide variety of uses, and with the elongation, the temperature and the tensile strength, these coatings are ideal for meeting a lot of the challenges that we see within containment areas. Fuel Containment Challenges To get to some of these fuel containment issues I'm going to talk about each of these photos and how and where we see the stresses and where you see failures. And I'll start over here on the left side. This is just a traditional saddle tank with a concrete pad. In this scenario they elected not to cook the pad but where we transition liner to concrete. This is a big transition piece here because there's a lot of flex and movement within this liner even within the concrete and where you see failures for typical liners is along the seam right here where you're bonding to the concrete. In this case we chose to go up over about six inches under the concrete to make the transition from liner to concrete pad. Traditional methods are batten bar, where you would have to drill in and actually breached the structural integrity of the concrete. So, in this situation, we don't have to do that and we can actually bond and we can spray right to it. Similarly, when you're doing aligner, a containment area, you find typically a lot of pipe penetrations and low-level pipe, so it's hard to get under stuff. In a traditional application, you would try to put a batten bar try to seal this in some way underneath these pipes, which is virtually impossible. In this scenario, here, you see these pipes, these pipes, you can't really tell in the picture, but some of these pipes are six inches off the ground. Very difficult to seal metal beams, I-beams running underneath them to support them as your pipe supports, these pipes are coming out of an asphalt wall that are double walled. So just in this one scenario, here you have several, several challenges within sealing and preventing any leaks. With traditional methods, this is virtually almost impossible to seal this with any integrity. Similar to what you see here below in this picture, there's a lot happening in this picture, there's a liner, a pump support, a vent pipe, I believe of some type coming out of the ground here. And what happens is, all of this stuff has aged. So not only has it moved, but it's structure is failing as well too. Another thing our coding does is not only makes the transition and gives you a confident seal between the structure and the liner to prevent any leaking, you actually can restore some of the integrity to the concrete pad in this scenario. This concrete pad, I was on site of this project, this concrete pad was actually crumbling and failing, we were able to coat up to it and coat around it and probably extended the life well excesses of 10 years just by coating and making this transition seal. A lot of times our coating and what we're doing here is not just sealing penetrations, but it's also extending the life of critical pump pads, tank pad, and virtually equipment that's needed in the field. To show some of the durability in this picture here, we actually illustrate this is one of our liners that is coated to a tank removal, the actual Bobcat had to go in and pick up a pipe that was being connected, he was able to drive in and drive out of the containment area without damaging the liner. Dan: Quick question. The question was, does this have to be a new liner system? Or can this technology be used with an existing liner of different materials? Pete: We can do to similar materials. Typically, what we've run into is HDPE or XR5 is traditionally the liner of choice, we can buy both of those and retrofit to an existing liner. That is possible. Yes. Dan: Okay, thank you. Pete: Okay. So, one of the things that we wanted to see like this liner here in reference to that comment, this is an actual HDPE liner where we actually had our, this is a polishing transition piece. This is a patented technology that we use to bond to the liner itself, but then use our spray applied SC 3900 to bond to the actual penetration. So, in this scenario, here, we're using our fully spray applied liner. So yes, it can be used with older material and new material. That's one of the best things about the system is the retrofitting is fairly easy with this system. Fence lines running through containment areas are easily handled. This is one of the one of the ones I like to talk about the most is there's a lot going on in this photo that you really may or may not know this is a pipe that's running underneath a roadway. This roadway is underneath this coating is asphalt. So, you have steel, asphalt, and this area here is dirt. So, we were able to literally bridge the bond between, we laid geo cloth sprayed that sealed it to the base of the pipe, we're able to spray the pipe and the asphalt and bond all of this together to create a watertight seal. I virtually have seen hundreds of applications where people have installed HDB or even an XR5 liner in this scenario here it is impossible to get a complete bond. This is probably the only method that I know of that's really truly accurate that is, in my opinion, maintenance free as well as fully sealed. Challenges Solutions Maintenance Issues Seal Irregular structures Embedment Issues Seal directly to tank bottom So, moving on, this is some of the stuff that actually probably was a in regards to that question. So traditional baton bar, see this a lot in the industry comes up, pops up, we can make this transition from liner to spray. One of the nice things is when we do spray this surface here, we actually stop a lot of that movement and we do get a permanent seal. But these are the types of issues that we've seen in the industry. Your liners just basically wrapped around a pipe and not really sealed; so, you have obviously a void there. Even with the embedment strips, what happens over time, embedment strips are jointed together, but over time the concrete flexes and moves and you have a breach. So, although the liner is attached here to the embedment strip, you actually have a void in your containment, where the liner strips are pulled apart by the movement of the concrete. Additionally, when you try to batten bar typically used in butyl tape and some caulk and in this situation here you can actually see this is this is this has got voids in it. Basically, this just aging probably looked good the day that it was done and aging, and weather, and UV, and just movement of the concrete actually pulls those caulks and those bolts and those bolt patterns loosen up and they come loose. Where we can actually spray attaches and bring it all the way up to here or just seal this area here for you as well. We don't need to actually bond to the liner, we could actually spray to the steel here. Some of the different irregular penetrations that we've sealed as corrugated pipe poured with concrete very difficult to bond to, we were able to spray in and seal up same as tank bottoms, we would actually bond to the bottom of the tank. And one of the advantages here that I'd like to discuss is when you do have a double bottom tank and we actually seal the base of it, this can be done with or without a liner. We've done several of these where we've just bonded to the tank itself and the ring wall to stop corrosion or deterioration of the ring wall. But one of the things that we do actually do that's unseen in this photo is, is where the tank shell is slotted through the tank. This is actually on the top side, you have your full API weld on the bottom side, it's only tack welded. So you have tack welds, that's that a guy can get down on his side and tackle this underneath that going around the outside of the tank. We were able to spray up under this and seal those voids between the tack welds; that's an entrance point for water and moisture to get in and corrode the bottom of the tank. So, it's a unique type of penetration that you don't really see and don't even know that it's there probably most people just don't realize it or don't think about it, but we can actually seal that and stop infiltration of moisture from getting up underneath the tank. Using this was our just an example of our poly seam transition piece that we use to actually bond to existing wires. So, this was an existing liner, they needed to bond to this tank. We brought in our transition piece welded it to the liner and then spray attached to that tank bottom. Same in these two photos here where we brought in a transition piece and we're able to make the transition spray to these penetrations. Any questions now? Dan: Nope, not yet. Spray Applied Structural Coatings Advantage Pete: So, going on along those lines of existing and penetrations existing systems you know some of the unique challenges that you have and the systems are conduit that runs through the containment areas already been supported, whether it's electrical or air whatever it may be, is bolted to these walls. We were able to seal around those without having to remove them. In this scenario, this whole thing would be coated eventually just wanted to kind of show the entrance point into the to the liner where we were able to seal it, as well as find unique type penetrations. This penetration with a concrete base on it, on an I-beam; extremely difficult to seal it; extremely difficult to guarantee any type of full seal. Another just quick example of a concrete penetration bas coming through a containment area and how we can actually seal it. So, these are all just three examples of things that we see typically in within containment areas. Concrete Containment Challenges Concrete a lot of times needs to be sealed. You have various voids, cracks or whatever it may be. Not necessarily a lot of these photos are showing full containment liners. That's not necessarily the case that needs to be done all the time. If you're not in need of sealing the entire concrete basin or containment, we can just come in and seal around your penetrations. So, I wanted to talk a little bit about those things that we see even though these are showing full containment. In these, this containment here, this was actually a PVC piece of pipe that was coming out of a discharge out of a building, and it ran through the containment area they needed for the settle tank here. We were able to just leave that in place and actually code it into the floor but getting a full bond, we actually strengthen the PVC pipe, but it was able to bond it and seal it so to prevent any leakage that was coming from the building getting into the container, because it was just water discharge, as well as your typical penetrations that we see ladders, supports and those types of things. This actually area was a block wall that we bonded to. So, we talk about abrasion resistance a little bit within our coating. One of the things you see here, whether this is just around a penetration, we have dock lines, a barge lines that are going to be laid back down on the surface and drag across the surface so the coating is very strong. And can be applicable to almost anything that we're talking about. As well as you have a drainage port in this, we were able to seal down into the drainage as well as this coding is handling truck traffic of 80,000 pounds in fuel loading spills and daily spills on this area. Along the lines of tight containment tattle tanks always seems to be a big issue, there always seems to be no room to do anything and you can't really line it. So, in this scenario, we're able to seal up the steps, seal up your painting sports, seal up your concrete wall. Again, does not necessarily require a full containment if you're having issues around the stairwell, or you're having issues around tank saddles, we can seal those individually as well, almost as if you're sealing a crack, but sealing the structure. It’s kind of gives a little bit more movement than most coatings and that's kind of what we want to illustrate here. This is actually a swinging steel door; we were able to coat it and seal this area here. Concrete cracking; this is this area here handles all types of movements in a cold environment. So, kind of just wanted to point to the actual structural ability of the coating to handle this is in a retention pond on a on a rail site. And it just kind of shows how much flexibility and movement it has. It's a freestyle environment as well as multiple different types of fuel sources. It's very, very strong in resistance to fuels and antifreeze and the different things that you find on various sites. The bottom picture here, we're going to just wanted to show how we could actually bond to your tanks support pipes coming up, as well as your tank, ring walls, and all your supports within a typical containment area. So more of a traditional type containment area you'd see here. Rail Pans, Roof, Tank Chin Seal, Ring Wall Sealing As with anything, there's penetrations with virtually everything that we see it within a containment area, you know, so, a railcar containment has a penetration of a railcar rail. We were actually able to seal to the base of the rails, which as you know, has extreme amount of movement. So, you have a penetration that you need to seal because obviously, there's openings underneath it to actually discharge into the environment into the ground. We can actually seal those penetrations as well while handling that immense movement that you find from a train constantly moving and going over with different loads different pressures, as well as in these environments, you have amazing swing and temperatures. So that is a large problem for a lot of these loading terminals and loading ramps. Kind of the boat, the bottom two here are kind of similar in nature, where you have a penetration from the tank, you got your caulk and butyl tape or whatever you may put in this crack to stop the infiltration. And since this is a penetration coming from you get your ring wall penetrating up and then you got your tank sitting on top of it, you have this bridge gap here that you need to bridge which we can do as well, we can coat directly to the steel with a little bit of prep and over the concrete ring wall. And this scenario here. This is all we did on the site, it was an asphalt site, believe it or not with asphalt base. But this is where they were having most of their penetration of most of their infiltration problems from water. So, we were able to seal this area here and prevent infiltration underneath the tank and preventing corrosion from underneath the tank. Similar to this one on the left; the one on the left was actually done more so even though this portion of the ring wall looks nice. This ring wall had a lot of freeze thaw effects that was going on and needed to be coated because if it had been left on uncoated, the freeze thaw would have destroyed this ring wall in a matter of years. So, there's a lot of spalling that you don't see in here, but there's a lot of spalling along this from freestyle events, and we were able to seal that up for future rain and future freeze thaw events that prevented a lot of that, almost like you would find when you cap a fence post. You're just preventing the infiltration of water. So instead of exfiltration, in that scenario, you're actually preventing infiltration. Dan, are there any questions at this point? Dan: No Pete, no questions yet. Steel Tanks – Roof – Internal Tanks Linings Pete: So, when we think about penetrations, and in the sealing of these items, it's not always necessarily in a containment area or external in the open. A lot of times you have these types of penetrations within your tanks. In these scenarios here, you can actually see these are these are aeration with inside of a tank. This could be pumping; it could be various things that are inside these tanks. In this one, this is an aeration unit, which we had to seal to the floor. Tanks had a lot of leaks in them. This was a wastewater application. But you'll also notice there's a bolt pattern like you see here, these bolt patterns on these bolted tanks are, are typically a job potential for leak or actual leaks over a period of time, they definitely have these problems. So, we can go in and we can in this scenario, we actually seal the entire tank floor, we can just do the bolt patterns, which are penetrating bolts coming out of the floor, we just actually seal around them. These areas here receive somewhere between 80 and 150 mils of coding at 3900 psi or testing that is done at 70 mil so these joints become very strong and resistant to leak. Dan: There's a question. What type of materials can you connect to with a typical SC 3900? Pete: Well, there's a method to almost attach almost everything. Obviously, any steel, concrete substrate, even plastics, although we do a lot of like past plastic pipe penetrations that are coming through a containment area where the product actually kind of shrink wraps around it and seals around it when then we will take almost as a hose clamp, and we will put it over tighten it down over and then coat that so it doesn't rust. So, we actually can seal around a piece of PVC, even though we may not be directly bonded to it. If I coated the PVC alone and did not put a radiator clamp or whatever you may have on there, it would still be sealed, but it could be pried off. So that's why we take the extra step of doing a radiator clamp. But we can pretty much find a way to bond most materials, whether it's utilizing our poly seam transition piece or poly seam primer methods, we can figure out a way to bond to it and seal it up. There are some instances where we can't, but stainless we can galvanize just as a little bit more in the prep process. Dan: Okay, thanks Pete. BCI Geodome Solution Advantage of a structural coating’s solution • No Downtime o Work can be completed while tanks are in service • Extended life repair o Coating’s life can be as long as 20 years or longer • Ability to handle various stored projects o Fills voids as needed and bridge gaps with varying thicknesses • Flexibility in repair requirements o Ability to move with the Geodesic dome thru expansion and contraction, high wind events o 100-5500% elongation pending products use o 3000-5500 psi tensile strength • Cost Effective Solution • Project cost for 10 storage tanks saved over a million dollars in real projects costs • Additional saved expenses can exceed even real cost in saved downtime and production Pete: So, in thinking about containment, again, not necessarily thinking about exfiltration we're talking about infiltration here. Geodesic Domes is another one of the systems where you see a lot of penetrations on a roof from your fire lines, your ladders going up on the on the roof, where you're trying to prevent the outside atmosphere or the rain from discharge or from coming into the tank and corrode or contaminating or getting on top of your roof and causing issues. So, when you look at this, you have everything from domes, to let in lights, to vent pipes to supports for the stairwells. We can actually coat around these all those this is done as an exfiltration, this is more of an infiltration issue, we can actually code around these penetrations and seal them up for from infiltration. And that's what is happening in most of these situations. All of these panels here we actually are just coating over the attachment point to the to the geodesic dome panels where they're having. Again, movement is what's causing these problems mostly when they it's brand new it's originally sealed with caulk or butyl tape and it's fine. But when that as these systems age, they become brittle and before long they start to move and that's where the system fails. Where we've got these in such situations that are in the islands where they're getting storms and hurricanes where we're actually did some hurricane damage repair for a client on their geodesic domes. We've done a lot for the military as well too. And basically, this strength of the system is really comes in the elongation of the product that allows it to move with these structures. BCI Industry Solutions Other industrial solutions provided by BCI • Geo-Dome Repairs Solutions • Secondary and Primary Fuel Containment • Crack Repair • Roof Coatings • Chine Sealing • Water and Wastewater tank coating • Secondary Containment over earthen substrates So that's most of everything I had on penetrations I'm going to discuss a quick review of some of the things that we do; BCI does. Obviously, you see the geodesic dome secondary, we do primary fuel contained, we do a lot of liners, crack repair, roof coatings in giant sealing wastewater, all types of secondary containment systems. So, one of the things that we like to pride ourselves on is providing industry solutions. We actually provide solutions. So, if you have any unique applications problem, they may or may not see it in this presentation, we probably have ran into it. We've done everything from Aqua ducks to above ground type containment of any type to storage tank roof. So, if you have any issues, please let us know. Internal Tank and Steel Coatings I wanted to review two other items here. And then and then we'll go to questions if there's any other questions. But some of the unique things we've done with this coating system is repaired holes in tanks that you see here in the photos. Again, this is a six-oil tank with infiltration was the issue really, it was eaten away by all the fumes from the six-oil that come out and less corrosive and ate away the top of the tank, we were able to seal the top of the tank and make it complete seals, so there was no water infiltration into the tank. Crack Repair and Joint Sealing With and Without Infiltration And then kind of along the lines of how we stopped the penetration leak is, if it with cracks, there's always voids in a seal or a penetration. So, what we do when we spray, it's very similar to what we're doing with a crack and that's what I wanted to show this, we're actually filling the void with the coating and then we're coating outside of that, and it becomes monolithic. So, you have crack movement. Even in this scenario, here, you can see we were able to seal around all this and basically what we do is utilize the coating to fill the voids and then coat or encapsulate that penetration. So that's one reason why I wanted to show that this slide here. Other than that, I mean, I pretty much always have on penetrations, and if there's any questions, I would be more than happy to answer. Dan: Yes, there is Pete, there was a question that came through the chat and then after that, I'll just unmute everybody. And if anybody wants to verbalize your question, we can go from there. But the question is, if I have an area with multiple cracks, where can you lay a liner over these areas and tie them in? Pete: I'm, if we're talking about concrete, we can do both. We can go over it with a pre sprayed or a sprayed over a geo cloth of 100 mils or whatever it may be, and then tie it in. Or like in this scenario here that you see in this photo, we were actually filled in all of these voids, and then coat it over the entire containment area and tied it to the good concrete. Dan: Okay. With that, we're wrapping it up here. I'm going to go ahead and unmute everybody, if anybody wants to ask a question, we're happy to do that. Pete: Well, as always, I'm going to resave this presentation and I believe Dan will send it out to the list of people so you actually have the presentation to refer to. But if you have the opportunity you need to email or you have any outstanding projects are anything that you need to look at, or you feel like this, this may be a solution for you please, feel free to reach out to me. I think my emails attached to everything, or Dan can copy that when he sends the presentation out and we'll be more than happy to help you out with it. Dan: Yeah, absolutely. So if you muted yourself, you'll have to unmute on your end, if you got a question. But yeah, so as a follow up to this will be, we have a recording of this webinar going on so, we're going to post that, we'll send you a link to that if you have folks that you want to share this with. We'll put it on our website as well so it'll be there forever. We'll send you a copy of the presentation as a follow up and you'll have different ways phone email that you can reach out to us and we'd love to work with you and help you solve your problems. So, if there's no questions, we'll, we'll wrap up here. One other thing if you do require PDH certificates, we've got that process streamlined a little bit better now. So, you can reply back to the email that you get. It'll come to me and I will be able to provide you with a PDH certificate so you can get your hours in. With that, we’ll wrap it up. Thanks everybody for joining and we'll see you next month. Upcoming Webinars and Events • November- Insulated Coating for ASTs-Safety Measures • December- Solutions for Renewable Energy
