Concrete waste kills fish by clogging gills and causing asphyxiation.
Locate a washout area at
least 50 feet from any storm drain, open ditch, or water body. Prevent
runoff from this area by constructing a temporary lined pit or bermed area
large enough for liquid and solid waste. Wash waste into the temporary pit,
allow the concrete to set, break it up and then use proper disposal sites.
Storage and Disposal
Exposed aggregate concrete washouts must be collected and disposed of
properly like all other concrete products. Store dry and wet material under
cover away from drainage areas. Train employees and subcontractors to
dispose of concrete properly. Do not allow excess concrete to be dumped on
site, except in designated areas.
Consider using porous concrete to allow stormwater to soak into the
ground, reduce runoff and recharge groundwater. Porous concrete is one of
Low-Impact Development (LID)
options that imitate the natural hydrology
(or movement of water) of your site. Use LID in your project to help protect
water quality and environmental resources.
