Construction Site Stormwater Runoff Control (Ohio T&M)

In Construction Site Stormwater Runoff Control , you'll learn ...

• How to develop and implement controls designed to prevent stormwater runoff at construction sites
• Effective methods of erosion control, such as stabilizing exposed soils and protecting steep slopes and waterways
• How to control sediment using perimeter controls, trapping devices, and inlet protection
• Best management practices (BMPs) for construction site wastes, spill prevention, and storage

Overview

To meet the Ohio Board's intent that online courses be "paced" by the provider, a timer will be used to record your study time. You will be unable to access the quiz until the required study time of 300 minutes has been met.

Polluted stormwater runoff is a leading cause of impairment to U.S. water bodies which do not meet water quality standards. Over land or via storm sewer systems, polluted runoff is discharged, often untreated, directly into local water bodies. When left uncontrolled, this water pollution can result in the destruction of fish, wildlife, and aquatic life habitats; a loss in aesthetic value; and threats to public health due to contaminated food, drinking water supplies, and recreational waterways.

This course covers methods to control surface runoff, sedimentation, and soil erosion, both during and after construction. Although the focus is on stormwater runoff control during construction, the lessons learned from this course can be applied to any project. For each stormwater control measure, the course discusses the applicability of the measure, siting and design considerations, limitations, effectiveness, and maintenance considerations.

Specific Knowledge or Skill Obtained

This course teaches the following specific knowledge and skills:

• Land grading to reduce steep slopes and stabilize highly erodible soils
• How to create diversions for runoff from higher elevations which can threaten property or worsen erosion
• How to preserve natural vegetation to provide erosion control, stormwater detention, and biofiltration
• Stabilization of construction entrances
• The use of check dams for erosion control
• How to use gravel or stone filter berms for sediment control
• The applicability and limitations of grass-lined channels
• The use (and limitations) of riprap to stabilize drainageways and outlets
• Stabilization of exposed soils using chemical stabilization, mulching, permanent seeding, sodding, and soil roughening
• Protection of steep slopes with geotextiles, gradient terraces, reinforced soil retaining structures, and temporary slope drainage
• How to protect waterways using temporary stream crossings and vegetated buffers
• How to balance the timing of land disturbance activities through construction sequencing
• How to minimize air and water pollution by using dust control measures
• Installation of dikes, wind and sand fences, brush barriers, and silt fences to provide perimeter sediment control
• Installation of sediment basins and rock dams to capture sediment before it leaves the site
• The application and limitations of sediment filters, chambers, and traps
• Measures to prevent debris from entering storm drain inlets
• Management of construction site wastes to minimize the risk of pollution
• Development of a spill prevention and control plan

Certificate of Completion

You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 40 questions. PDH credits are not awarded until the course is completed and quiz is passed.
