Concentrations of Particulate Matter Emitted from Large Cattle Feedlots in Kansas

Effective August 1, 1978 the Government of Canada ordered that all future federal regulations of significant economic import, covering the subjects of health, safety and fairness be preceded by the publication of a formal socioeconomic impact analysis (SEIA). Environmental protection regulations are included. I encountered my first public reaction to this announcement at a conference in Ottawa on the subject of “Jobs and the Environment”. A union official duly observed that the SEIA was obviously industry’s answer to having to carry out Environmental Impact Assessments. Not much later, I was told by a senior environmental official of an overseas country that what SEIA really did was to place the burden of proof on governments as to the need for control, rather than leaving industry to show that their activities were not damaging to the environment.
