The Western Oil and Gas Association is a powerful actor in the air pollution domain especially, from the 1940s up through at least 1988, but I can't tell what happened to it after that. It may have become folded into one of the other oil lobbying organizations, like the Western States Petroleum Association, but I just don't know, which I think is a bit weird. It was based on Los Angeles, and represented the major oil companies here: Standard, Texaco, Arco, Phillips, etc. etc. in all their changing names as they go through break ups and consolidations. Needless to say they exerted legislative power over the air, but they also shaped the knowledge landscape as part of that strategy. So in the late 1940s and early 1950s it commissioned research from the Stanford Research Institute to begin challenges to early air pollution control measures, squaring off against the Los Angeles County Air Pollution Control District.
