Construction Activities and Storm Water
Potential Tracking, Wind Erosion, and Construction Site Management Issues Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs Construction Activities and Storm Water Construction projects tend to Disrupt the existing area by exposing soils and changing drainage patterns Store and use materials that contain or are themselves pollutants Require ancillary activities that are potential sources of pollutants We have already addressed how construction projects tend to disrupt the existing area by exposing soil and changing drainage patterns. Now we will discuss how Construction Projects tend to: Store and use materials that contain or are themselves pollutants Require ancillary activities that are potential sources of pollutants 3

Tracking Control Issue

Left – construction site with obvious track-out onto the paved road. Right – exit next to a water tank that leaked or spilled - Bad location. 4

Wind Erosion Control Issue
Potential Tracking, Wind Erosion, and Construction Site Management Issues Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs Wind Erosion Control Issue Dust generated from a construction site can be both a water pollution control problem as well as a public hazard. Water or a chemical stabilizer can be applied to construction sites / haul roads to prevent this type of problem. Explain difference between Wind Erosion and Dust: Wind Erosion is caused by natural processes (wind events.) Construction activity (such as trucks traveling on a dirt road) exposes fine sediment (dust) that is then carried in the wind. No wind erosion controls used 5

Construction Site Management Issues

Water Pollution Control Strategies during Construction
Potential Tracking, Wind Erosion, and Construction Site Management Issues Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs Water Pollution Control Strategies during Construction Prevent storm water contact with disturbed soil areas (DSAs) Protect DSAs from erosion Minimize sediment in storm water before discharge Control discharges of sediment from other sources Prevent non–storm water discharges Prevent storm water contact with other potential construction site pollutants Water pollution control strategies during construction are as follows: Control discharges of sediment from other sources Prevent non–storm water discharges Prevent storm water contact with other pollutants 10

Control Sediment Discharge From Other Sources
Potential Tracking, Wind Erosion, and Construction Site Management Issues Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs Control Sediment Discharge From Other Sources Tracking Controls Stabilized Construction Exits Street Sweeping and Vacuuming Sediment Discharge From Exiting Vehicles and the Forces of Wind can be controlled by: Tracking Controls Stabilized Construction Exits Street Sweeping & Vacuuming Wind Erosion Control Usually spraying water to keep soil moist.

Prevent Non-Storm Water Discharges
Potential Tracking, Wind Erosion, and Construction Site Management Issues Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs Prevent Non-Storm Water Discharges Manage concrete waste Employ proper dewatering operations Fuel vehicles and equipment off-site or in designated areas Use covers or platforms to catch debris over water Manage sandblasting operations Lets talk about preventing non-storm water discharges. Water not from a storm, relates to discharges and dewatering of other pollutants. Go through bullets, mention BMPs associated with each The picture shows the use of a signed concrete washout area to prevent discharge of concrete wastes. 12

Prevent Storm Water Contact With Other Pollutants
Potential Tracking, Wind Erosion, and Construction Site Management Issues Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs Prevent Storm Water Contact With Other Pollutants Minimize storage and non-essential activities Store materials/wastes in watertight containers Cover stored materials/wastes Prevent run-on Clean up spills of materials/wastes Another good strategy is to prevent storm water contact with other pollutants like oils, fuel, chemicals, etc. Go thru bullets The picture shows a materials storage area. The contractor placed a concrete pad with a berm or curb to contain spills,and it is covered with a wooden roof. It appears though that the area is getting crowded with containers and either has to be enlarged or some of the barrels removed. Containment volume: refer to the manual WM-1 for the temporary containment volume 13

Example Project PS&E Phase 14 Roadway Widening Central Expressway
Potential Tracking, Wind Erosion, and Construction Site Management Issues Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs Example Project Roadway Widening Central Expressway Widen from two to four lanes Elevate roadway Construct wall and bridge structures Grade embankments Purpose Assess impacts and problem conditions Select and deploy BMPs Identify SSPs for separate bid line items Note to Instructor: Refer to the handouts again. During the sample project, emphasize identifying problems and choosing BMPs to counter the problem. Remind the students that a variety of similar BMPs could be used in each situation. Select one and give reason. Possible reasons: Less expensive, easier to install, contractor familiarity, district preference. Example: The site may have cobbles or othr soil conditins that would make driving in long stakes for silt fence impossible, consider other BMPs like fiber rolls or gravel bag berms. Even the shorter stakes used for fiber rolls may present a problem. However, gravel bags may break down quicker in the sun. Things to consider. Don’t use this example in District 7: Example: A temporary straw bale barrier may be selected since it is readily available, and is expected to be abandoned in place. A temporary silt fence, on the other hand, is rarely installed correctly and would have to be removed before the end of the contract. PS&E Phase 14

Adobe Creek Bridge Structure Access Point Stockpile Area New Roadway
15 This is the same project. The notes are copied here for reference. This project will complete the Central Expressway by widening the remaining two-lane portion to four lanes. The roadway will be raised and three of the intersections will be converted to under crossings with new bridge structures. As right of way is limited, a combination of 1:2 earth embankments and concrete retaining walls will be used. For the purposes of this example, we’ll work with a single plan sheet representing the west end of the project. At this location, there will be grading for a new embankment slope and an access road will be built. Additional right of way has been obtained for a storm drain outfall near where the bridge structure will be replaced. A new drainage system will serve several roadway drain inlets. The ditch at the drainage outfall flows to Adobe Creek (Sheet P-2). A new concrete retaining wall supports the south side of the roadway and wraps around to contain the abutment. Commercial properties are to the north and south. A temporary construction easement (TCE) has been obtained to facilitate construction. This area will be used by the contractor for staging and material storage.

What If? 22 Our project encountered the following conditions:
Potential Tracking, Wind Erosion, and Construction Site Management Issues Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs What If? Example Project Our project encountered the following conditions: Some 800,000 cubic yards of dirt had to be transported through a publicly used street. The soil type on the construction site was a combination of clays and silt. A sediment-impaired water body was located within 100 feet of the construction exit that would be used by the hauling equipment. The head of the RWQCB lived just up the street. For such conditions, additional tracking controls may be necessary. Are the standard BMPs for tracking control adequate? 22

Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs Tire Wash Example Project A tire wash may be necessary to control the sediment at some sites. 24

Develop a Non-Standard Special Provision
Potential Tracking, Wind Erosion, and Construction Site Management Issues Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs Example Project Develop a Non-Standard Special Provision There is not an SSP for the tire wash BMP. Therefore, a non-standard Special provision or NSSP may be necessary. This could essentially be adding a water source to the temporary construction entrance or a complete portable unit that recycles the water. District Construction may have already found out what works for this kind of soil in their area. TC-3 Tire Wash 25

Following the instructions from the Construction BMP Consideration form, answer the questions on Checklist CS-1 Part 4. Check yes if standard dust control is anticipated to be adequate. Check no if they are not and select additional BMPs. These BMPs may be the same as the ones selected for Soil Stabilization. See Ref Tab Page 8 27

Standard Dust Control vs. More
Potential Tracking, Wind Erosion, and Construction Site Management Issues Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs Standard Dust Control vs. More Example Project Appropriate uses would be in air quality management districts and high wind areas. Here is some guidance on how to determine whether standard dust control is not adequate and additional controls are necessary. Rule of thumb Additional measures are probably necessary if a “Dust Control Plan” is specified in the contract documents. Otherwise, standard dust control practices are most likely sufficient for the project’s wind erosion control. 28

Wind Erosion Controls 29 Wind erosion control
Protect DSAs from wind by applying soil stabilization BMPs Wind Erosion Controls 29 Use the project plans to determine what area may need dust control. This would be the entire area to be disturbed including stockpiles.

Non–Storm Water Discharges Allowed by a Separate NPDES Permit
Potential Tracking, Wind Erosion, and Construction Site Management Issues Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs Example Project Non–Storm Water Discharges Allowed by a Separate NPDES Permit Dewatering operations for water removal Water from coffer dams Groundwater in excavations Accumulated Rainwater Requirements vary by district Some non-storm water discharges are allowed under separate NPDES permit. Remember, so far we have been discussing the requirements of the general Construction NPDES permit. Another permit may be necessary for the discharge of water from dewatering groundwater or coffer dams. It is important to identify these requirements early in the design process. Coordinate with the District Stormwater Coordinator and/or the Construction Division. The Construction Division sponsors a course on the Management of Construction Site Dewatering Operations. In the reference materials, you will find a list of dewatering permits for each Regional Board. This slide addresses Test Question 14: Which of the following statements is/are TRUE regarding non-storm water discharges? (A)Non-storm water discharges are never permitted. (B)Some non-storm water discharges are allowed by separate permits. (C)Some non-storm water discharges can be permitted by the Construction Storm Water Coordinator. (D)Both B and C. (E)I don’t know. 34

Read or have someone read the question. Answer yes if stockpiles are anticipated. As you select the BMPs we will go back and forth to the plans and check the complete box. You will use this information later as you prepare the cost estimate. Lines item BMPs with a separate SSP will be estimated separately and incidental sediment and erosion control BMP items will be estimated as a lump sum. See Reference Material Tab Page 10 36

Waste Management and Materials Pollution Control
Most non-storm water BMPs are housekeeping measures and left to the contractor to describe in his SWPPP. Since there are retaining walls and bridge structures on this project, including concrete washouts is appropriate. Providing temporary cover (e.g., plastic sheeting) to cover stockpiles, in addition to slopes, should also be considered. Although not shown on this plan sheet, temporary creek diversion systems, clear water diversions, and stream crossings are non-storm water BMPs that should be considered by designers. Stockpile covers Linear barriers 37

Temporary Stockpile BMPs
Potential Tracking, Wind Erosion, and Construction Site Management Issues Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs Temporary Stockpile BMPs Example Project Construction Site Management Temporary Soil Binder Temporary Mulch Temporary Hydraulic Mulch (Bonded Fiber Matrix) Temporary Hydraulic Mulch (Polymer Stabilized Fiber Matrix) Temporary Erosion Control Blanket Temporary Cover These are the stockpile BMPs. As a note, You may also want to consider a temporary cover BMP, depending on the quality of the stockpile. If you want to retain top soil on site, it is appropriate to use temporary seeding on the stockpile. A complete list of SSP is included in the reference material tab on Page 18. 38

These cover incidental issues on a construction site. If there are significant issues, you may want to ALSO include a specific SSP covering that issue. SSP CSM is used in all projects. Slide address question #2 Which of the following statements is/are TRUE concerning Standard Special Provision Construction Site Management? (A) The specification includes general housekeeping and non-storm water type BMPs. (B) A practice covered in this specification CANNOT be identified as a separate bid line item. (C) SSP can be utilized with projects that disturb < 1 acre of soil (WPCP projects). (D) Both A and C. (E) I don’t know. This is covered in Module III Slides 43-48 43

Potential Tracking, Wind Erosion, and Construction Site Management Issues Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs Construction Site Management Provides for management of Hazardous waste Contaminated soil Concrete waste Sanitary/septic waste Liquid waste These are the housekeeping, non-storm water type BMPs included in this SSP. These cover incidental issues on a construction site. If there are significant issues, you may want to ALSO include a specific SSP covering that issue. For example, if sign posts will be installed as part of this project, this SSP will cover the concrete waste from the placement of the sign posts. If the contract will also place a large amount of concrete pavement, you may want to also include SSP - 405/6/ or 7 - Temporary Concrete Washout Facility/Bin and include that item as a separate bid item. 44

Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs What if you had a situation that required a specific BMP that didn’t have a standard special provision? Some BMPs can be a combination of SSPs. Some Districts already have NSSPs for some of the same situations. Find an appropriate SSP or develop a non-standard special provision for the situation! 56

Determine the appropriate Construction Site BMPs for the project
Potential Tracking, Wind Erosion, and Construction Site Management Issues Water Pollution Control Strategies Selecting Appropriate Tracking, Wind Erosion, and Construction Site Management BMPs Class Exercise Time Selecting Appropriate Construction Site BMPs Project Information $6 million upgrade handrail and sidewalk project Project disturbs > 0.25 ac of soil (project not a short form) Estimated cost of all line item BMPs equals $66,000 Have the class refer to page 4 of the Exercise tab. The students should read through the project and use the Construction Site BMP consideration form from Appendix E of the PPDG. Refer to the handouts. The concentration is obviously on Construction Site Management (Housekeeping, non-storm water type and waste and materials management BMPs) but if they identify erosion and sediment controls, they should include them even if minor. There is a second exercise (page 5- Culvert Replacement) that can also be worked at this time if there is time. If time is short, omit this exercise. Determine the appropriate Construction Site BMPs for the project Exercise Tab Page 4 57

Module III Summary 58 We have just covered the following topics:
The potential tracking, wind erosion, and construction site management issues on construction sites The water pollution control strategies behind the selection of Tracking, Wind Erosion, and Construction Site Management BMPs The selection of appropriate Tracking Control, Wind Erosion Control, and Construction Site Management BMPs using the Caltrans-developed process We have addressed the BMPs for tracking, wind erosion, and construction site management – housekeeping, waste and materials management, non-stormwater type BMPs. We looked at the overall strategies for controlling discharges from these sources. We went through the Construction Site BMP Consideration Form and the associated Construction Site BMPs checklists answering questions to select the proper BMPs. 58

Questions Any questions: 59 Calaveras 49, New Melones Reservoir

What do you know, some more questions!
Q1 Permits are either under the construction permit or Caltrans permit. Sometimes a separate permit is necessary but the Design SWC does not “permit” non-storm water Q2 Construction Site BMP Consideration Form Q3 The general categories discussed in this module are tracking controls, wind erosion controls and construction site management BMPs: any answers in these categories are adequate. Any BMPs mentioned in this module area acceptable answers. Can non-storm water discharges be permitted by the Design Storm Water Coordinator? When selecting Construction Site BMPs, where does the prudent Designer start? Name a few Construction Site BMPs. 60
