The Department of Environmental Quality was established during his term as chairman of the Mines and Minerals Committee.

In addition, Chairman Prosser worked for passage of the Wyoming Mined Land Reclamation Act and the Industrial Siting Act, both laws being the backbone of state environmental protection legislation. The Mined Land Reclamation Act requires mining companies to restore disturbed areas to their natural state and was a prototype of similar legislation adopted nationally. Prosser sponsored the Wyoming Beef Council Act, which established a checkoff system to collect funds to promote the sale of beef. Representative Prosser also worked successfully to remove the [[ad valorem tax]] on livestock, which saved ranchers $6 to $10 per year per head. He also worked to improve brand inspection laws.<ref name=obit/>

From his capacity at the Stockgrowers Association, Prosser cautioned ranchers not to overproduce cattle during periods of high prices. He reasoned that once a downturn in the economy took effect, the ranchers would be unable to make good profits on future sales. "The real culprit is the guy who looks back into the mirror while preparing for your daily shave," Prosser told cattlemen at their annual convention in June 1977.
