2.Provide a sufficient number and size of waste containers (e.g dumpster, trash
receptacle) on site to contain construction and domestic wastes.
3.Locate waste containers at least 50 feet away from storm drain inlets and surface
waters unless no other alternatives are reasonably available.
4.Locate waste containers on areas that do not receive substantial amounts of runoff
from upland areas and does not drain directly to a storm drain, stream or wetland.
5.Cover waste containers at the end of each workday and before storm events or
provide secondary containment. Repair or replace damaged waste containers.
6.Anchor all lightweight items in waste containers during times of high winds.
7.Empty waste containers as needed to prevent overflow. Clean up immediately if
containers overflow.
8.Dispose waste off-site at an approved disposal facility.
