[00:00:00.810]Now we come to our final module,
[00:00:02.820]Good Housekeeping Practices.
[00:00:04.650]It's not just sediment we are tasked with controlling.
[00:00:07.380]It's all potential pollution sources on a job site,
[00:00:10.470]from concrete to vehicle fluids
[00:00:12.120]and solid waste to sanitary facilities.
[00:00:14.610]Good housekeeping is an important part
[00:00:16.290]of construction site compliance.
[00:00:19.050]Good housekeeping includes all the effort made
[00:00:21.030]to minimize exposure of pollutants other than sediment.
[00:00:24.330]It is a daily and often hourly practice
[00:00:26.340]on the construction project.
[00:00:28.140]A proper understanding of things to look for
[00:00:30.150]and take care of can be considered
[00:00:31.980]the most important good housekeeping practice.
[00:00:34.890]The goals of good housekeeping
[00:00:36.270]and pollution prevention on construction sites
[00:00:38.400]include the following,
[00:00:40.200]prevention of discharges of solid materials
[00:00:42.450]and non-stormwater pollutants from discharging offsite,
[00:00:45.930]controlling offsite vehicle tracking and construction dust,
[00:00:49.770]minimizing exposure of construction
[00:00:51.570]and waste materials to stormwater.
[00:00:54.030]Let's start by talking about the practice
[00:00:55.710]of concrete washout.
[00:00:57.450]It is a requirement for a construction site
[00:00:59.520]to require designated
[00:01:00.690]and properly installed washout locations.
[00:01:03.600]This washout slurry from the chutes of concrete trucks
[00:01:06.210]has a very high pH level
[00:01:07.980]and can be extremely harmful to aquatic life
[00:01:10.500]if it reaches a water body.
[00:01:12.300]Use the following tips to contain concrete wash water.
[00:01:15.780]Designate a specific location, or multiple locations,
[00:01:19.350]for concrete trucks to be washed out.
[00:01:21.840]Use poly material to line the bottom of the washout.
[00:01:24.840]This is now a requirement in NDOT specifications.
[00:01:28.350]Clean out concrete washout areas when the BMP is 75% full.
[00:01:33.390]When installing washout areas,
[00:01:34.920]make sure that the structure
[00:01:36.000]is providing sufficient storage and containment.
[00:01:38.730]Straw bales can be used as an alternative
[00:01:40.770]to an earthen berm.
[00:01:42.480]For smaller jobs, even plastic kiddie pools
[00:01:45.090]could be used as washout pits,
[00:01:47.010]disposed of properly when the material is dried.
[00:01:50.160]Concrete truck suppliers should be informed
[00:01:52.080]of the locations of the washout areas when they arrive.
[00:01:55.110]Make sure that the washout area
[00:01:56.610]is clearly demarcated with signage
[00:01:58.740]as well as noted by someone on the temporary erosion
[00:02:01.320]and sediment control plan.
[00:02:03.240]When the containment area is half to two thirds full,
[00:02:05.970]remove the dried material for disposal.
[00:02:08.430]NDOT recommends full removal of materials
[00:02:11.460]taken offsite to a proper disposal location.
[00:02:14.970]Next, let's talk about construction access,
[00:02:17.190]also commonly referred to
[00:02:18.540]as construction entrances or exits.
[00:02:21.270]One of the biggest violations, complaints,
[00:02:23.220]and safety concerns for construction sites
[00:02:25.290]is tracking of mud and debris onto roadways.
[00:02:27.960]This can occur along the roadway as vehicles enter
[00:02:30.390]and exit at will or at defined locations.
[00:02:33.330]Staging areas, commons areas,
[00:02:35.070]even campsites related to a particular construction project
[00:02:38.130]are all candidates for needing a construction access.
[00:02:41.400]The rock material can be either crushed stone
[00:02:43.620]or broken concrete, two to four inches in diameter.
[00:02:47.010]Remember, a construction access
[00:02:48.630]should be a bit uncomfortable to drive over
[00:02:50.880]because its job is to knock mud off of tires.
[00:02:53.670]There are proprietary exit systems on the market
[00:02:56.250]that may also be specified for use by the project engineer.
[00:03:00.240]For installation of construction access points,
[00:03:02.670]remove the vegetation
[00:03:03.870]and excavate any soft soils from the exit area.
[00:03:06.840]Compact the subgrade if needed.
[00:03:09.360]Grade the exit such that flows will not go out
[00:03:11.520]onto the adjacent street.
[00:03:13.080]Install a subgrade geotextile prior to placing the stone.
[00:03:16.830]A construction access should accommodate
[00:03:18.570]the largest construction vehicle in length and width
[00:03:21.390]that will exit the site,
[00:03:22.860]ideally allowing for three revolutions
[00:03:24.780]of that vehicle's tires.
[00:03:27.060]As mentioned previously,
[00:03:28.320]there are several proprietary access products on the market.
[00:03:31.590]Most of these products are more suited
[00:03:33.120]to smaller construction sites and equipment,
[00:03:35.370]as well as in urban project areas.
[00:03:37.620]The project engineer and prime contractor
[00:03:39.600]will select the right BMP for the job.
[00:03:42.180]For a lot of proprietary products,
[00:03:43.980]follow the manufacturer's specifications for installation.
[00:03:47.910]Sediment tracked within the construction site
[00:03:50.160]is much less of a risk
[00:03:51.360]than sediment tracked off the construction site.
[00:03:54.060]When you observe sediment track out,
[00:03:55.980]it must be cleaned up immediately,
[00:03:57.750]especially during wet or hazardous conditions.
[00:04:00.930]Proper management of construction access
[00:04:02.850]will save costly cleanup and traffic incidents.
[00:04:06.330]Now let's review hazardous materials.
[00:04:08.730]In the course of a construction project,
[00:04:10.800]it can become common to see containers
[00:04:12.510]and pieces of equipment out of place
[00:04:14.340]and fall into disrepair.
[00:04:16.230]What is important is to identify these materials
[00:04:18.780]and find proper locations
[00:04:20.160]and secondary containment for each one.
[00:04:22.740]Proper material management is a daily
[00:04:24.630]and often hourly commitment.
[00:04:26.760]Diligent preparation for storage and spill response
[00:04:29.400]is key to managing a spill or leak.
[00:04:32.130]Prior to beginning work on the project,
[00:04:34.020]the contractor shall prepare
[00:04:35.310]a spill prevention and control plan
[00:04:37.410]that clearly states measures to prevent a spill,
[00:04:39.930]contain a spill, clean up a spill,
[00:04:42.480]dispose of contaminated materials,
[00:04:44.700]and train personnel to prevent and control spills.
[00:04:47.880]The plan should include the notification contacts
[00:04:50.580]as well as the procedures and timeframes
[00:04:52.680]to address the situation in the event that a spill occurs.
[00:04:56.160]One of the most important aspects
[00:04:57.630]of the spill prevention control plan
[00:04:59.220]is secondary containment.
[00:05:00.870]Hazardous materials management specification requires
[00:05:04.050]that petroleum-based products with bulk storage
[00:05:06.150]55 gallons or greater must have secondary containment
[00:05:09.630]in the event of a leak or spill.
[00:05:11.700]Petroleum-based products include things typically found
[00:05:14.190]on construction sites like motor oil, gasoline,
[00:05:17.100]and transmission fluid.
[00:05:18.930]It's important to note
[00:05:19.890]that the secondary containment integrity and capacity
[00:05:22.770]must be adequate to contain any potential spill.
[00:05:25.830]Also, spill kits should be staged
[00:05:27.540]and stored in accessible locations if needed quickly.
[00:05:30.720]Lastly, for leaking equipment that is staying on the site,
[00:05:33.630]use drip pans to catch oils until repairs can be made
[00:05:36.450]to stop the leak.
[00:05:38.400]with any hazardous materials or any work involving them,
[00:05:41.550]make sure to conduct these activities away from waterways.
[00:05:44.580]Remember the following activities and materials
[00:05:46.770]are not allowed in designated restricted use areas
[00:05:49.320]on NDOT projects.
[00:05:51.570]Vehicle and equipment storage with the exception of cranes,
[00:05:55.050]soil or material stockpiles,
[00:05:57.210]unless protected by adequate BMPs,
[00:06:00.210]portable toilets,
[00:06:01.620]hazardous material storage,
[00:06:03.420]or concrete washout areas.
[00:06:05.850]The general contractor as part of meeting
[00:06:08.040]the hazardous materials management specification
[00:06:10.860]is required to train employees involved
[00:06:12.810]with the project on proper response to a material spill.
[00:06:15.900]Before a spill happens, it's important to understand
[00:06:18.480]what the expectations are for everyone involved.
[00:06:21.210]All workers on the project should be trained
[00:06:23.040]on best management practices available
[00:06:25.530]for secondary containment,
[00:06:27.210]available spill response equipment and materials,
[00:06:29.820]including safety and cleanup equipment,
[00:06:31.950]maintenance techniques to minimize equipment leaks,
[00:06:34.650]procedures for containing, diverting, isolating,
[00:06:37.830]and cleaning up a spill,
[00:06:39.390]and how and when to notify proper authorities
[00:06:41.940]such as the Nebraska State Patrol,
[00:06:43.890]or Nebraska Department of Environmental Quality.
[00:06:47.250]Waste management would include management for solid waste,
[00:06:50.190]hazardous waste, sanitary waste, and recyclables.
[00:06:53.880]It's not often thought about,
[00:06:55.380]but construction sites can be contributors of litter
[00:06:57.630]to adjacent property and waterways if not managed properly.
[00:07:02.100]In a regulatory inspector's eye,
[00:07:04.200]obvious solid waste debris strewn through
[00:07:06.120]a construction site is a classic indicator
[00:07:08.880]that perhaps there are more deficiencies to be found.
[00:07:11.760]Even proper location
[00:07:13.050]and anchoring the portable toilet facilities
[00:07:15.540]is an aspect of waste management that cannot be overlooked.
[00:07:19.020]A clean site is an efficient site
[00:07:21.060]and proper waste management should be a part
[00:07:22.950]of every stormwater pollution prevention plan
[00:07:25.590]with updates to the temporary erosion
[00:07:27.840]and sediment control plan
[00:07:29.100]to point out locations of these facilities.
[00:07:32.280]While we have focused in previous sections
[00:07:34.050]on sediment runoff,
[00:07:35.400]another source of offsite sedimentation is windblown dust.
[00:07:39.570]Typically, we consider dust control
[00:07:41.340]to fall under the category of good housekeeping.
[00:07:44.100]Dust can become an issue from large, bare areas of soil
[00:07:46.830]exposed to strong winds,
[00:07:48.540]from construction traffic leaving a site
[00:07:50.310]onto a road or highway,
[00:07:51.990]from haul road traffic within a construction site,
[00:07:54.570]and also from dry concrete saw-cutting.
[00:07:57.720]It's important to stress the benefit
[00:07:59.220]of vegetation and erosion control,
[00:08:01.290]especially when it comes to wind erosion.
[00:08:03.900]Preservation of vegetation minimizes soil exposure to wind.
[00:08:07.650]Watering haul roads during dry times
[00:08:09.960]and applying soil tackifiers to bare soils
[00:08:12.420]where there's no traffic
[00:08:13.320]will all lessen the chances of excessive dust.
[00:08:16.020]Sweeping or vacuuming adjacent access roads
[00:08:18.300]can reduce the soil on hard surfaces.
[00:08:20.760]Minimizing dry concrete saw-cutting methods
[00:08:22.980]is also recommended.
[00:08:24.810]Wrapping up section four, here's some of the main takeaways.
[00:08:27.930]Install adequate concrete washout pits
[00:08:30.090]based on the size of the project.
[00:08:32.220]Install stabilized construction exits
[00:08:34.320]at appropriate locations to minimize track out.
[00:08:37.380]Follow the general contractor's
[00:08:38.820]spill prevention and control plan, SPCP.
[00:08:42.570]Ensure adequate secondary containment
[00:08:44.490]for petroleum-based products.
[00:08:46.740]Have good waste management systems
[00:08:48.480]and site them accordingly.
[00:08:50.070]Limit project dust from wind erosion
[00:08:52.110]and construction traffic.
[00:08:54.120]Now return to the course menu
[00:08:55.950]and take the quick five question quiz
[00:08:57.660]to move on to complete the NDOT Erosion and Sediment Control
[00:09:01.170]Installer Certification course.
