Of course, reducing the emissions of the stationary source was still the main treatment method before people found modern management method successfully. At that time, a lot of people used garbage incinerator in their backyard; they were against the ban of garbage incinerator because they thought chemical factories were the main source of pollution. Until 1958, garbage incinerators were banned after the establishment of garbage collection plan. The first efficient modern management method was added leakproof hose on the fuel gun. When officials reviewed the air pollution control of Los Angeles in 1997, they said that adding leakproof on the fuel gun was the most economical and effective measure during 50 years.
