Attached : Lecture, question and student replies as reference. The paragraph will be posted on the same discussion board. Question : This lesson emphasizes avoidance or minimization of pollution by scheduling and phasing construction to prevent bare soil contact by rainfall, keeping runoff on site, and applying permanent or temporary cover to bare areas judiciously when work finishes or stops for a period of time. On jobs that you are familiar with, how common are these preventative measures? If this proactive approach is the norm in your area , what do you think are the most important factors that stimulated adoption? If this approach is uncommon, what do you think is the main reason(s), and what will have to be done to make this approach the norm rather than the exception?
