• Understand water pollution control strategies behind for these types of BMPs

• Select Tracking Control, Wind Erosion Control, and Construction Site Management BMPs

• Identify Standard Special Provisions (SSPs)

Construction Activities

and Storm WaterConstruction 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

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

10

Potential Tracking, Wind Erosion, and Construction Site Management IssuesWater Pollution Control Strategies


Control Sediment Discharge

From Other Sources Tracking Controls• Stabilized

Construction Exits• Street Sweeping and

Vacuuming

11

Wind Erosion Control



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

12



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

Example ProjectRoadway WideningCentral Expressway

• Widen from two to four lanes

• Elevate roadway• Construct wall and

bridge structures• Grade embankments

Example Project

What If?

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.

Are the standard BMPs for tracking control adequate?

Standard Dust Control vs. More

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.

Appropriate uses would be in air quality management districts and high wind areas.

• Dewatering *


* SSP 07-346 should be adequate when water from dewatering can be discharged within project limits. If estimated quantities of water will be greater or the dewatering operation will be complex, use SSP 07-347 – Temporary Active Treatment System. 47

What if you had a situation that required a specific BMP that didn’t have a standard

special provision?

Find an appropriate SSP or develop a non-standard special

provision for the situation!56

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
