Appendix I - Stormwater Management Plan

2.6 Material Disposal
The accumulated sediment found in stormwater treatment
and conveyance systems must be handled and disposed of
in a manner that will not allow the material to affect surface
or ground water. It is possible for sediments to contain
measurable concentrations of heavy metals and organic
chemicals (such as pesticides and petroleum products). Areas
with the greatest potential for high pollutant loading include
industrial areas and heavily travelled roads. Sediments and
water must be disposed of in accordance with all applicable
waste disposal regulations.

It is not appropriate to discharge these materials back to
the stormwater drainage system. Part of arranging for
maintenance to occur should include coordination of disposal
of solids (landfill coordination) and liquids (municipal vacuum
truck decant facility, local wastewater treatment plant,
on-site treatment and discharge). Owners should contact
the local public works department and inquire about how
the department disposes of their street waste residuals.
Stormwater360 will determine disposal methods or reuse of
the media contained in the cartridges. If the material has been
contaminated with any unusual substance, the cost of special
handling and disposal will be the responsibility of the owner.
