Take motor oil , paint , antifreeze , pesticides , and solvent containers and leftovers to a hazardous waste drop-off site rather than pouring them into storm drains or sewers .
把机油、油漆、防冻剂、溶剂容器或剩余物送到有害废物投放地,不要把它们倒在雨水渠或下水道中。
One way to keep the oil flowing is to heat the pipe . That , though , is costly . Another is to pump antifreeze , in the form of methanol , down it from time to time . But methanol is toxic , so this creates an environmental hazard .
The st anthony falls bridge that replaced the failed i-35w bridge in minnesota has temperature sensors that can communicate with antifreeze spray systems to prevent the bridge from icing up .
