Board of County Commissioners - Regular Meeting

Okay. Hey folks, my name is Chris Desidarati. Thanks for joining us today. Um, we are on our final session of the pollution prevention academy uh, stormwater compliance. Uh, like I said, my name is Chris Deserati. I I work for West. I've been here for a little over 10 years. Uh, I'm going to serve as your facilitator for this meeting. Um, and you'll hear a presentation from Galen and Rob, who I'll let them introduce themselves shortly, but some quick housekeeping. Please use the Q&A and the chat features, which are available at the bottom of your screen as little buttons that uh that will let you put in any questions, we'll answer at the end of the presentation. or if you have any problems uh as far as equipment or access uh we'll have Alexa and Chris and Todd in the background paying attention uh to those those features uh and they'll be able to help you help you with that. So yeah, again uh let's go to the next slide, Chris. Okay, uh we're going to be talking about storm water compliance today. I'd like to start off by introduce by letting our speakers introduce themselves. Uh Galen, why don't you go ahead and start?

Uh good afternoon everyone. Thanks for joining us today. My name is Gail Novski. I'm an environmental services specialist and I've been with West for uh almost three years. And I'll I'll let Rob introduce himself here. Great. Thanks. Hi, my name is Rob Livingston. I work for uh water environment services and as a as a environmental um specialist I've been involved in you know one form or another of this kind of source control work since 1998.

Great. Thanks Rob. Uh yeah Rob and Gayen will be available after the presentation to answer questions. Uh we'll we'll stop the recording then and go ahead and get in with the Q&A, but I'll hand it back over to Gayen to uh get us going. Thanks, guys.

Awesome. Thank you, Chris. Um so, today we'll talk uh talk about stormwater compliance and uh Wes's private stormwater program. Uh next slide, please. So, a quick overview. Uh today, we're going to we're going to briefly touch on West as an organization and our service area. a brief stormwater 101 and why compliance matters for w water quality. Uh after that we'll focus on the west private stormwater program. We'll walk through uh what a typical stormwater inspection looks like. Uh what property owners can expect. We'll show common deficiencies we see in the field and how they can be addressed. Uh we'll share success stories and best management practices as well. And uh finally we'll wrap up and leave some time uh to answer some questions. Next slide, please. So, here at West, our vision is to be a collaborative partner in building a resilient clean water future where all people benefit and rivers thrive. It's our job as staff to uh protect public health and support the vitality of our communities, natural environment, and economy. uh stormwater programs are a big part of that mission because what happens on the land in our service area typically affects our rivers and streams. Uh next slide. So here is a quick map of uh our our stormwater service area. Wes manages stormwater services across two primary service areas called uh rate zone 2 up in that right hand corner with Happy Valley uh and rate zone 3 in that bottom left corner. Uh rate zone 2 includes sanitary sewer services uh and storm water services across uh for about 75,000 people in urbanized areas of unincorporated Clackamus County and the city of Happy Valley. Those areas drain

into several watersheds uh including the Clackamus River to the south, Kellogg Creek and Johnson Creek, which those two ultimately drain into the Wamtt River. Rate zone 3, as I mentioned in that bottom left corner, uh we only provide storm water services in that in that zone to the city of Riverrove and surrounding rural areas that drain into the lower Twallatin River. So these two zones include a mix of urban and rural environments which means uh storm water infrastructure and compliance uh challenges vary across the service area. Next slide please. So before diving into uh the inspection program it's going to I want to review some basic stormwater concepts and why storm water management matters. Next slide. Here we have two graphics of a natural landscape and a urbanized landscape and developed a storm water runoff is rain or snow melt that flows over hard surfaces like rooftops streets and sidewalks and parking lots. These surfaces prevent water from soaking into the ground creating runoff that moves really quickly across the landscape. Uh unlike waste water from toilets, sinks, showers, uh storm water is typically not treated at a facility and in most cases it flows directly to the near the nearest stream, creek, rivers, wetland, picking up whatever uh pollutants are in it in its path. Next slide, please. So, here's a graphic from the EPA that does a good job at showing what pollutants uh storm water can pick up, such as oils, chemicals, trash, sediment. Um, because this runoff is typically untreated, it can degrade water quality

in nearby streams and rivers. Examples include increased turbidity um from erosion, raises water temperatures, uh and it can deliver excess nutrients and storm water pollution can threaten public health by contaminating drinking water sources or making making uh recreation unsafe. It can also damage habitats such as uh fish spawning areas and reducing uh biodiversity. Next slide, please. Uh, storm water programs are driven by several levels of regulation. At the federal level, the EPA sets national water quality standards through the Clean Water Act of 1972. Uh, in Oregon, the Department of Environmental Quality or DEEQ implements and enforces these requirements. uh local jurisdictions such as West and other cities carry out storm water programs uh and inspections to meet those federal and state requirements. Next slide. So, here at West, we operate under several environmental permits. Um these are the three main ones that we we work with uh for storm water, but I really want to focus on that first one, the the MS4 permit. This is the regulatory driver for many of our programs at west uh which uh this permit regulates our municipal storm water systems. This permit requires uh programs such as public education, construction site inspections, pollution prevention uh and industrial and commercial inspections. And our private storm water inspection program here helps us meet these requirements set by DQ and EPA. Next slide, please.

Uh, this is aerial photo of Wes's Carly Creek's water quality project that was constructed back in 2018. This project is a constructed wetland located adjacent to the Clackmus River there on the left, less than half a mile upstream of several drinking water intakes that provide clean drinking water to more than 300,000 residents in the region. Uh the Carly Creek wershed contains over 400 acres of industrial properties and uh heavily traveled roadways. This storm water runoff is treated um through this system and removes oils, metals, nutrients. Uh so this facility was really designed to treat and capture storm water runoff uh from ind industrial areas before it reaches the river. Next slide, please. So now that we've covered uh some background, I we want to dive into the west private stormwater program. Uh this program focuses on stormwater systems that are located on private property such as multifamily, commercial, and industrial sites. Um, and all these sites play critical roles in treating storm water runoff uh and and protecting local waterways, but they really do require ongoing maintenance and oversight to function properly. Next slide. So, our private stormwater program focuses on several key goals. Uh, we we're focusing on protecting local waterways by preventing pollutants from entering storm water systems. We are ensuring private stormwater facilities are functioning properly and being maintained. We are helping businesses meet regulatory requirements. We're identifying risks early during inspections. Uh we're encouraging preventative maintenance. We're building collaborative relationships with

businesses by providing guidance and technical support. Um and we're constantly tracking our work and improving our programs through adaptive management. Next slide, please. So, who is inspected? Our our goal is really to visit every private uh stormwater facility or site at least once to understand the the site conditions and potential risks. After the initial visit, we prioritize future inspections based on risk. Uh higher priority sites include those of those of you who might be operating under a 1200Z stormwater uh permit through DQ. U other other facilities include hazardous waste facilities, industrial sites that handle regulated chemicals. Um but really at the end of the day, we're really inspecting any property where activities could potentially contribute pollutants to storm water uh storm water systems or receiving streams. Next slide, please. Uh, so next we'll talk about what a typical stormwater inspection looks like and what you can expect. Next slide. So inspections begin with West staff selecting facilities and notifying them uh whether that be through mail, uh, phone call, email, or showing up during normal business hours. Um, inspectors then arrive and present identification. Uh the main part is really the site walkthrough in the fac in the facility inspection where uh us as inspectors evaluate stormwater infrastructure and potential pollution risks. This is going to include looking at catch basins uh outdoor storage, other treatment systems uh and also vegetated facilities. Inspectors document conditions will

update site mapping if needed. will communicate findings to the property owner or the responsible party. Uh if issues are identified, we'll typically start with a notice to correct with some clear clear timelines and we'll follow up to confirm that the issues have been resolved. Uh once all required actions are completed, we provide final documentation once uh the inspection is closed out. Next slide please. So during inspections we focus on really main four four main areas. Uh first is going to be the gray infrastructure such as catch basins, manholes, pipes, other treatment systems. uh you know then we look at above ground above ground systems such as vegetated stormwater facilities u for example swailes or ponds planters u we're also looking at overall site conditions and pollution risks such as spills stains other improper storage um with high risk uh and we also um we also look at you know best management practices is uh if there's for example there might be we ask if there's spill kits uh other containment systems and we check for just general good housekeeping practices on the property. Next slide. And so after the inspection, property owners receive a summary report um with with photos and findings. If deficiencies were identified, we'll provide guidance on corrective actions and timelines. Um, we'll give we'll give some options of what we typically see other property other facilities do. Uh, we'll follow up we'll we'll schedule

follow-up inspections. Uh, that will typically those will typically occur um if there are deficiencies noted. And we we really like to provide technical assistance to facilities and other resources to help uh the property owners or responsible parties maintain their systems to uh the best extent possible. Next slide. And now I'm going to hand it over to Rob. All right. Thanks Kayen. So in our inspection program, we've uh we've done about 700 inspections and visited roughly 700 sites. So, we've noticed some common themes about some deficiencies and we'll talk about how to address them. Uh, next slide, please. So, the top issues we see are kind of listed in the boxes up there. We got pulling damaged catch basins, vegetated and vegetation or vegetation and vegetative facilities, spills, and damaged structures with missing components. So, our inspection program, like mentioned, is a a two-pronged approach. We're looking at the storm system and all its components. Um, as far as maintenance, you know, are they being cleaned regularly? Are they full of sediment? And also the pollution prevention aspect where we're looking at outdoor storage and evaluating risk. Next slide. So, um we'll start with catch basins because they're the most common structure um on property and I'll use the terms catch basins and storm drains pretty interchangeability interchangeably, but they're uh they're just two terms for the same exact thing. And they're also the first or generally the first point of entry of storm water into a storm system. And a lot of folks think that's the first line of defense, but it's actually, in my opinion, it's

the second wave of defense. Um, where parking lot sweeping is really the first line of defense. It's the most preventative um and cost-effective measure of keeping sediment out of your storm system. So, uh, as as evidenced in the the photo here, uh, parking lot sweeping could have really really benefited the storm system where the catch basin is is full to the great and then some. So, next slide, please. All right. Catch basin are generally located in the lowest part of the grade where storm water will naturally sheet flow across pave surfaces and reach storm drain and you know picking up pollutants along the way. Um this this one was a little lower than most. It's buried um in looks like some landscaping had to be dug up to to be uncovered for maintenance. Uh this is where having as drawings of your of your facility really really comes in handy so you can find these when they get uh you know covered up and and are out of sight and out of mind. Next slide. So we'll talk about catch basins a little bit more. Catch basins have two functions. They really capture the floaters and the sinkers that uh that storm water will mobilize and the sinkers sink pretty obvious the heavier particulate matter that drops to the bottom of the sump. So the sump is the very from a distance from the very bottom of the catch basin up to the lowest point of the discharge pipe. And then the floaters of course are going to be floatable material. And when we say floatable plumes, we're talking about oils and fuels and vehicular fluids. Things will float on water. And

that's that kind of box shape there in the photo. That's like the outlet structure. The outlet pipe is behind that. And what that does is it forces the water to discharge from the catch basin from the subsurface. And in doing so, all the floatable pollutants and material should be retained in that catch basin until the next time it's clean. Um, in the photo we we're showing the uh the maintenance port there is like wide open, but yet there's a plug uh sitting on top of the the box. And so that in its current state there is not able to capture any floatable materials. When it rains, it's going to go straight through that. So the easy solution here is uh simply put the plug back in the maintenance board. And so all the plugs need to be in place for that to function properly. All right, next slide. So here's another catch basin with the outlet baffle box uh gone. In fact, the the entire catch basin is pretty much rusted out. So uh you know like like many things, these have a finite service life and this one is pretty much reached the end of it. Next slide. Another catch basin. Uh, this one should have a hinge lid that covers that box. It's gone. And so what will happen during a rainstorm is the water level in that catch basin will be elevated and it was over top that outlet structure and all the material that's been retained inside floating on top will just simply pass through it. So that one needs the lid replaced. Next slide. And here's another catch basin that has uh some structural problems with its outlet baffle. It's mostly rusted away and it's full of sediment. So this one uh really benefits from from repair and

cleaning. Next slide. So fortunately, a lot of the a lot of the fixes for these catch basin issues are are pretty simple. uh could be as easy as just putting that sheet metal patch right on top of the on top of the hole so it's somewhat watertight and will hold back flowable pollutants. Next slide. Whoops. There we go. Okay, here's another another easy fix with a sheet metal patch over the outlet port. It's got a hole in it for maintenance and they've installed a nice handy removable plug in case they need to do any any line J. Next slide. This is another repair where the hinged lid and the box have been replaced. Next slide. And here's another example of the hinge lid being replaced again. Next slide. And and a lot of times sometimes just replacement is the better option like we saw with that rusted out catch basin. um these they don't last forever. All right, next slide. And like we mentioned, the second prong of our two-pronged approach is uh is the pollution prevention aspect of it. And so here's uh here's a photo of of about this is about as bad as it gets what we find out there in the field. Um these barrels stored outside exposed to storm water. They're not covered. There's no containment underneath. Uh some of them have some of those dome lids on the barrels which do sort of help, but the the one there is not it's not covered at all. It looks like rainwater has floated the contents out of the barrel all over

the ground. And like we mentioned, if it's on the ground, it's in the water. So the next time it rains, rain water can mobilize whatever that is uh to the nearest catch basin where it will just enter the storm system and be conveyed out to the through the storm system, you know, to the nearest creek, stream, river, what have you. Uh, and like we mentioned, uh, you know, if you're if you're within the Clackmus industrial area, most of the storm water in that area goes directly to the Clackmus River, which is a drinking water resource for 300,000 people. And I don't think any one of those people would want to be drinking any of that. Next slide. Um here are some uh some IBC totes that we see that are used and and misused for storing many things. Uh the plastic cell or bladder um in these is really it's it's a thicker version of a milk jug and they have a valve at the bottom that could be opened by anybody and the contents released. So, if you do have these on site, ensure that valve at the bottom is tightly closed and capped. And if it was up to me, I would remove the the handle entirely. They can also, if they're exposed to UV outside, they can be uh they can become brittle over time and crack or be punched with a forklift or um be damaged, you know, just kind of halfhazardly. So, um, there are better containers out there for storing things. Next slide. So, um, while we're talking about IBC totes, here's a this is a picture of Kellogg Lake that was oiled up by some

IBC totes that were, uh, where they had were used for storing used motor oil at auto repair shop. There was a fire at the at the repair shop which melted the plastic of the containers and all the used motor oil they were storing was released into the storm system and made its way into Kellogg Lake. So um like I said there there are better containers for holding some things. Next slide. So here's another uh storage example. this these materials are stored in like a three-sided roofed uh enclosure. So, that's good. Um, but if you notice, you look at the bottom, there's no there's no containment under any of those any of those containers and it looks like there's some staining and there's been some leakage of whatever those products are. There's minimal labeling of these containers. So uh if your if your facility is subject to inspections by the fire marshall or DEQ uh that could be an issue also. Next slide. Elicit discharges. We find these on occasion. U the storm water system was intended for rain and rain only. And we like to say only rain down the drain. They're not they're not trash cans. This looks like uh some paint material, maybe some drywall mud dumped in the catch basin. Uh this is, you know, clearly an illicit discharge. Subject to fines, cleanup costs. So, u you know, keep manage your manage your waste products properly and and don't don't put it in storm drains, please. Uh next slide. Here's another elicited discharge. This doesn't look like it's an

intentional dumping like the last photo, but uh the end result is the same. We got some sort of material making its way into the storm system from some other activities. So, if you're doing activities doing work outside, make sure that those waste products don't enter don't migrate towards the storm system. Um or this could be from a leaky waste container. So, if it is a leaky waste container, contact your waste hauler and uh demand that they bring you one that doesn't leak. And if they can't do that, then I would suggest reaching out to the county solid waste people who regulate waste haulers and they will ensure that you get a container that doesn't leak. Uh, next slide, please. So, again, catch basins are for rain and rain only. They're not for washwater disposal. Next slide. All right. Here's an example of a a cooking oil waste waste oil container placed um near the curb uh where it was struck by a vehicle. So, if you have these kind of containers um at your business, ensure that they're they're tucked away and and safe and can't be uh get struck by vehicles. Um I'm sure none of you want to uh you know, deal with this kind of thing or have the time to uh to devote to dropping everything you have and and and jumping on this with cleanup and with cleanup costs and potentially a fine. So, um, be be aware of where your waste containers are. Next slide, please. Uh, speaking of cooking oil waste containers, this is how we generally

find them. There's generally almost always oil on them, all around them, on the ground, and like we said, if it's on the ground, it's in the water. So my suggestion for this would make make it easy as possible for your employees to make sure that fryer oil gets in the container instead of on it. You know, maybe provide a step stool or some easier method for them to get the oil in it. Maybe maybe use two half empty buckets instead of one bucket that's plum full. Just, you know, whatever whatever whatever it takes to get the material properly stored. Next slide. Some of the facilities that we visit have on-site fueling. Um, notice here that uh none of this is covered like the gas station generally is. Uh, the large white container looks to be like a double walled container. Uh, but the pumps and dispensers are exposed to storm water. The yellow container most likely a diesel tank. Um, as you can see by this the staining down the sides and or on the ground u appears to be a leak there or some other mechanism isn't working properly getting a lot of diesel fuel um you know leaking out of that on the ground and again it's going to affect storm water log. So this is this is completely preventable. Next slide. All right. So this little island here in a parking lot um is a sto it's part of a storm water system. It it accepts storm water from the asphalt surfaces and that kind of turquoise colored pipe is the overflow for it. It should have like a domed grate on the top to keep things

from entering it and plugging it up. So, um, you know, right now it's pretty vulnerable to things entering that pipe and plugging up that system that will be extremely difficult and expensive to remove. And, you know, any any 12-year-old vandal is is probably looking for things to drop down that pipe right now. Next slide, please. Um some properties had uh vegetative facilities as part of their storm water um system and were installed as such along with everything else on the property and um sometimes they are just neglected. They get mistaken for landscaping and they're definitely not a set it and forget it type of device. So, um, in our program, we like we have a phrase called protect your pond. And so, everything upstream your pond, um, is the easy money as far as keeping sediment and other debris out of your pond. So, uh, this one here has been, you know, long neglected. It it needs a fair amount of work. and should mention that we've seen pond rehabs for some of the larger ponds reach easily into the six figure dollar amount. So do whatever you can to protect these uh protect these structures from incurring um neglect and uh just lack of maintenance. It's a good investment. Uh next, please. Here's a couple of uh cartridge filters in a vault. These uh these perform some filtering of storm water. And the manufacturer criteria for these is when they accumulate a quarter inch or more of sediment and debris on the top of the

filter, that's when they're saying maintenance is maintenance is needed for these. So that's about where these two in the photo are at right now. Next slide. some cartridges accumulate a little more. Next, so maintenance for these um entails removing the cartridges from the vault. The vault is is cleaned out. The cartridges have the they have a granular media inside. So that gets that gets removed and replenished with fresh media and then the cartridges are reinstalled in the vault. So, these two are ready to be put back in service. Next, please. I see these uh these fabric filter bags under storm water grades at at some sites and u to filter out, you know, the the sinkers that I talked about earlier, the larger sediment debris type of type of pollutants. Um they need maintenance, too. and they're they're not a they're not a substitute for sight maintenance. So, in the photo you can see tire tracks and that loose debris there. This is a this is a good example where you know parking lot sweeping would be uh a bit more cost effective and just kind of head off a lot of that material um resulting in a lot less you know honestly less maintenance work for you and less changing out of those filters. So, next please. This is uh this is a sediment manhole. It's part of a storm system. So, there's a deep sump uh underneath those two pipes that you see. It's probably I

think probably like 3 feet deep or so. And so, that one is pretty full. And how we measure these is we we have piece of the PVC pipe that we kind of probe around in the in the sediment and and kind of feel for how much is there. And if they stand if that pipe stands up all by itself, it's it's likely time for some maintenance. Next, please. All right. This is a different type of manhole is a flow control manhole. So the smaller corrugated pipe you see right there has a has a a smaller hole in the bottom of it. That's the that's the outlet orfice. That's the flow control that restricts flow out of it. Um if you look carefully at the bottom there's a gate valve that you can see is near that where the beam of lights hitting the surface of the water and you'll notice that that valve is open. All right. So when the valve is open, that completely defeats the whole flow control purpose and just kind of circumvents its function. There should also be a long handle that's attached to that to that valve that that gate valve that extends up to the top so you can open and close it from the surface. So it's a little a little maintenance that needs to be done here too. U next please. Wes's uh Wes's surface water rules apply in the residential areas also. So if your business um entails visiting uh residents properties and doing work on their homes, then make sure that any waste products that are that are generated in doing that work don't make their way out into the street or the catch basin. Uh this photo looks like uh what we find um when like some concrete

slurries are discharged. U so you know save yourself the the time and expense of the cleanup and the cost and potentially a fine of this kind of discharge at a customer's home. So with that, I'll hand it off to Galen for some corrective actions.

Awesome. Thank you. Can we go to the next slide, please? So, um, as Rob showed in several of these photos, when deficiencies are identified during inspections, corrective actions typically fall into a few common categories. Uh with with catch basins, it's mostly going to be cleaning the sediment and debris out of it, repairing any of those baffles, those boxes or plugs inside. Uh and or repairing the grate itself if it's badly damaged. For vegetative facilities, it's going to be more weeding, sediment removal, replanting, or clearing blocked flow path paths uh to restore the proper treatment. With the underground vaults and detention systems, we're it's we're mostly seeing just vacuuming out the sediment or oils and repairing any internal structures. Uh with water quality and flow control structures, it's going to be just sediment removal, maintenance of internal components such as the shear gate that you saw in the one of those photos that was open. uh making sure the handles are operating as designed um and orphoses aren't uh obstructed or maybe even replacing filter media like you saw in those uh filters in the vault. And then finally just mostly uh sitewide issues like cleaning up spills, storage practices, moving moving things inside, getting them covered um or their damage conveyance systems that need to be addressed. And so most of these really are just routine maintenance issues that keep systems functioning. Uh next slide. So we saw a lot of the uh stuff we don't like to see. Uh but I do would like to share some good examples of stuff we do we do find uh out in the field. Um and these typically make inspections, you know, a lot quicker. Next slide.

So this first photo shows uh above ground vegetated facility. Um the plants are looking healthy. There's there's no weeds. The gravel is visible for dissipating some of that uh volume of water that's coming into the facility. None of the flow paths are obstructed. Um and that riser cap uh is on the uh on that overflow as well. Next slide. here. Same thing. We have some healthy vegetation, maybe a little bit younger, probably planted within the past couple years. Um, we can see that inlet pipe to the facility. That's something I always like to stress to uh facility. Uh, we're responsible parties and owners is make sure you can see where the water's coming in and going out. Um, there's a little bit of rock underneath that pipe to just dissipate some of the energy. There's no obvious weeds. There's no trash. Um, next slide. Here's an example of a vegetative facility that uh is a little more mature, has dense vegetation. Uh, the curb the curb cut inlet there on the bottom right corner is free of debris. um there, you know, there there may be a few weeds there in the back, but that's the one of the most common things we see is uh weeds. So, make sure you know what plant species are intended for that facility and ones that can uh overtake those intended species as well and cause more of a maintenance issue. Uh next slide. Uh here's an example of a larger pond. Uh this vegetative facility has very mature vegetation. It's dense. Uh there's no volunteer trees such as cottonwoods or willows growing in that pond bottom uh that might might

channelize or accumulate more sediment and debris. Um there's irrigation uh in there set up for maybe some drying months. So, make sure making making sure that's oper, you know, not just uh making sure it's operating uh well, not damaged or broken because sometimes the irrigation can just turn into trash eventually. Um, and there's no obvious sediment accumulation at the inlets or outlets. So, proper maintenance is really key to keeping these vegetated facilities functioning effectively. Next slide. Um, so Rob was talking about some uh outdoor storage, showing some examples of what could happen if you don't have proper secondary containment or cover. Um, this first photo uh is just a shows a good example of a secondary containment pallet that's used to help prevent spills and leaks from from reaching those catch basins. Next slide. Here's an example as well of some other totes and barrels on secondary containment pallets. Um, and you really want to make sure you have the right sized pallet uh secondary containment for the material that you're storing. Uh, there there on the right side there looks like there's three containment pallets under, you know, under those two barrels. you know, at least one of those can be maybe moved to that left side of the storage area where there's some other buckets of material that are just sitting on a a wood pallet. So, just being aware of what you have and and uh you know, potential risks on the site. So, this is just a very simple but effective way to prevent pollution. Next slide, please.

So, here's an a photo inside one of the manholes. This is uh another flow control manhole. Uh you can see the uh shear gate is closed. You can see the handle coming up. Um so it's you can easily get in there and maintain it if you need to. And that hole um the small diameter hole inside that corugated pipe is that orphice. So um making sure that's not obstructed or damaged. Um just checking your internal components to make sure there's no cracks or other damages. Next slide. Uh here is another uh pollution control or flow control manual here where that's been actually freshly serviced. So we can actually see the concrete casting there at the bottom. We can see that orifice hole. There's it's not obstructed. There's no there's maybe a couple rocks in the bottom of that, but overall if we're if we show up and we open open a manhole and take a look inside, this is a good example of what should things should look like after it's been uh freshly maintained. Next slide, please. So, next we'll share a couple uh before and after photos of some success stories and what what improvements can look like. So, these are real examples um over the past several years that we've we've uh seen from property owners to correct issues. Next slide. So, as you saw in uh the photos Rob showed of the cartridges, this is just a before and after photo of them being maintained. Um there's over over quarter inch of sediment and floatables in that left side. Um and the facility contacted the manufacturer, got new uh media, um potentially even new cartridges, but

um and also cleaned out that vault that they're stored in. Next slide. Here's a side-by-side comparison of a, you know, before and after photo of a simple uh catch basin baffle repair. Um, if you do have someone on staff that's handy with uh with with welding, this could be a really simple fix. And this is what happened in this this photo. They were able to fabricate on a new lid um that brought them back into compliance. Uh, next slide. And this is just a photo of a uh a simple repair of just going going maybe to your local hardware store and getting a new cleanout cap um and just you know reinstalling it to uh restore that function of the of the intended uh design. Next next slide please. So, here's a couple photos um of the facility that utilized uh the pollution prevention resource center uh their their funding to acquire some secondary containment and store in a storage set um for their used oil. And so, they were able to This is just a great example of a facility being proactive and utilizing local resources to uh prevent uh potential spills. Next slide. And here's a before and after photo of that photo that Rob showed of that sedimentation manhole. Um, and the photo on the right is it after it's been cleaned up. So, yeah, there's about 3 4 feet of uh added capacity for for having some of those sediments and other pollutants settled out. And so um this is this maybe has never been uh never been maintained. Um sometime these sometimes these

structures are a little bit more out of sight. They're hard to open and access. U you know they could be covered by vegetation. So really it's important to know uh know what you have on your site, know where things are. Next slide. So, as Rob mentioned, the uh rehabilitating a pond could be upwards of um you know, six six figures. It could be really expensive investment. Um but it does deliver long-term benefits. And these these systems really only have a um you know, a given life lifespan. So by restoring this p the pond's capacity by taking out the accumulated sediments and um invasive species, it's really going to be improving water quality treatment and the overall uh uh pond's performance. So this first photo uh the pond was restored to its original design uh when it was constructed. It just had the sediment removed, invasive species removed. it uh we're able to slow down the velocity of the storm water entering it. Um the energy dissipation by adding some new rock and a little settling chamber. And uh the plant community has also been reestablished which really helps with pollutant removal and just overall ecosystem health. Uh next slide please. Um, and here's another example of a pond uh before and after where we when we first saw this pond, it was obviously neglected. Um, storm water was essentially flowing in and just right out. There was almost no detention capacity. It wasn't serving its intended function um just due to all that accumulated sediment and debris. Um, and that storm water was able just to channelize a straight path through to

the outlet. Um so by removing that sediment um this facility was able to regain its uh or you know increase its uh detention capacity. Uh the plant community was restored um really improving some more pollutant pollutant removal and ecosystem health. So when upstream stormwater assets such as catch basins, manholes, parking lots are wellmaintained, stormwater ponds require a little bit less frequent attention, mainly just routine vegetation maintenance. Next slide, please. Um, and finally, this is an example that shows just an old dumpster that's been vandalized there on the left. Um, the lids are missing. It's probably rusted out, leaking. um it's an eyesore. You can simply just contact a garbage uh waste hauler for a new container and simple changes like this can make a big difference in reducing storm water pollution. Next slide please. I'm g hand it back over to Rob.

All right, thanks Kayen. So we're just going to talk about few methods to how best effectively manage your stormwater system. Next slide. Fortunately, storm water storm water is simple, right? Simple solutions, easy problem. So, we mentioned talked about parking lot sweeping. That's the most cost-effective method of reducing sediment. And you know, in the back of your mind, always think protect your pond if you have one. U catch basins, inlets, uh clean out the debris regularly. Again, they're going to be upstream of the pond. you're going to, you know, prolong the service interval of that expensive detention pond by by uh doing the the cheap and easy, you know, cleanouts of catch basins. Um, you can also mark the drains with messages like no dumping drains to stream type of stencils so you know employees know or not to dump things down them. uh with your vegetative facilities, you know, it's going to be weeds, removing sediment, uh maintaining the plants, and then the vaults and manholes and other underground systems, you know, they're just larger versions of catch basins. So, uh you know, schedule routine cleanouts for those as well. They may not need to be cleaned out as often, but they still need routine maintenance. Again, uh keep an eye on elicit discharges. Again, only only rain down the drain. Catch basins or trash cans and uh you know, have spill kits on the site and train staff to use them. And then again with the outside storage, there's always things get put outside and forgotten about um that can become problems and liabilities. So, make sure that uh you know those are covered. You

know, permanent roof is best, a temporary roof is better or even a well secured tarp is better than nothing. Uh the secondary containment, we talked about that. And then the dumpsters, keep those in good condition as well. All right, next slide. So, why maintenance matters? Well, primarily it it it protects water quality and prevents pollution um you know from leaving the site, reduces pollution to ecosystems, wildlife and drinking water resources. It ensures regulatory compliance. You can avoid fines if your if your facility has a 1200 Z industrial storm water permit, you know what I'm talking about. Um it also keeps people like me out of your hair. Um you know, flooding and property damage, it's pretty obvious. Do you want your property to drain properly? Uh system longevity, especially the vegetative s uh facilities, they're they're extremely expensive uh to get back into working order and to their original configuration. Um you know, that pays off over time to protect those. And then um facility appearances. Yeah, this you know um the vegetative facilities they they can look good and treat storm water at the same time and you know minimizes emergency repairs you know catch catch the small problems early prevent cost of repairs or system failures you know look out for your future self and as we all know time is money. Next please. So what regular maintenance looks like for all these I think we we've we've talked about it but we'll just repeat the message. It starts with inspections. So regular inspections of all the key storm water infrastructure on the site. You

know the catch basins, the swailes, the ponds, the vaults, um even the the manholes and vaults and other things that you may not even know you have. You know I have shown people um a lot of storm water infrastructure they had no idea that was on their property. So, make sure you know your system and check it out um once in a while. Sediment removal and cleaning is the big thing. Maintaining vegetation in your in your vegetative facilities. Um inspect for unauthorized illicit discharges. Remember, only drain down the rain or only rain down the drain and respond immediately with cleanup. also uh notify us if you have an elicited discharge at your site and it's it's a requirement through our our rules section 7.3.4 um to notify us. We we do have signs with our contacts information on there that we can give you. So if you do have a spill, you can respond to us and report that. And you know storage areas are properly covered and contained. Also waste management you know cover the waistbands to keep trash and debris from uh you know washed into the storm water system properly storing chemicals and materials that could be mobilized uh during a rainstorm. recordkeeping documentation. Document your inspections and maintenance activities like an O andM log book. Uh you track your repairs and maintenance actions taken which could be used to report to Wes. And also this is really important maintain draw updated drawings of the storm water system on your site and any modifications made. So it'll help out other other people besides yourself

if they need to uh you know address some storm water issue in a hurry. Uh again train your staff on pollution prevention, spill response and proper white waste management and u you know train staff to communicate and report issues of any storm water system failures that they that they discover. Uh, next slide. So, I'll mention the recordkeeping again. Um, it's it's in our rules. All privately owned storm water systems must be inspected annually and a report submitted to water environment services per section 4.5.2 of Wes's rules. So, we don't require uh cleaning of of storm water systems every year, but we do we do ask that owners at least inspect those and then report to us on on on their activities. So, this is this is easily done through we have an online uh reporting tool through our website where you can uh quickly input that data into into the tool. it it probably take 10 minutes. Uh, next slide. We also offer our what we call our storm drain cleaning assistance program or SCAP. It's a voluntary program. It offers a reduced flat rate on cleaning catch basins. And so it's just a flat fee per catch basin. There's no upch charges. There's no fuel s charges, no mobilization charges. So, if you're interested in this, look for a postcard around September. This is when we uh we mail those out for the fall season. Sign up through Wes. We will we will create a we create a

customer list that we'll forward on to on the contractor who will contact the customers and and schedule the work. And so, we offer this to make it easier for property owners to easily and inexpensively maintain the storm systems. Next, please. And so help is available. So Wes's storm water standards and staff are available for to assist you. Um if you have a vegetated facility, clean water services has a private um water quality facility program guide. Both EPA and Oregon DEEQ have guidance documents for industrial facilities. Uh the National Stormwater Center has some good uh BMPPS to assist you and we mentioned the pollution control pollution prevention resource center or the PPRC earlier. They are funded by the Clackmus River water providers and they have funds to assist businesses with pollution prevention BMPPS like we showed um in the photos there that the storage cabinet for the oil drums. the uh the bunds they have, they're limited and it's first come, first serve. So, if you uh if you have some storage needs or other other BMPs that you want to uh employ at your site, you know, uh get a hold of us and we can put you in touch with the PPRC. Uh next slide. Uh okay, so some key takeaways at the the end of our presentation. Um, storm water is a community effort and everybody needs to do their part. You're a key player in this. U storm water is a is a has a cumulative effect both you know good and bad. Everybody needs to everybody needs to pitch in. Uh know what's on your site. Understand your

storm water system and keep it functioning properly. Regular maintenance matters. It's a good investment, right? You change the oil in your car, it extends the engine's life. storm systems. Same practice. Uh common issues are easily easily prevented with simple fixes and Wes is here to help not just enforce. So we offer support, technical guidance and inspections to help you succeed. Next slide. So um here's our contact information. Feel free to reach out to us and uh thank you for attending today. and we'll turn it back on over to Chris.

Thanks, Rob and Gayen. That was that was an awesome presentation. And uh yeah, like Ruck Rob said, uh please use Gayen and Rob as as experts on our rules and and BMPPS at your property. Um we'll end there and then I think switch to the switch to the Q&A session. economics. I have some announcements.
