RI Cuts off Comments

On 'Gas' Formula RulePROVIDENCE, R.I. - The Rhode Island Department of Environmental Management has set today as the cutoff date for comments on its proposal to reduce the volatility of gasoline in order to reduce harm to the ozone layer.

DEM officials estimate that while the cost of gasoline will go up 2 cents a gallon because of the formula change, automobile engine performance will improve so the actual cost is 1.5 cents a gallon.

Volatility requirements, which vary from state to state according to weather and altitude, are measured by in terms of the pressure exerted by vapors from evaporating gasoline. The so-called Reid Vapor Pressure is given in terms of pounds a square inch.

At a hearing early this week, representatives of three oil companies and the Rhode Island Petroleum Association opposed the proposal to reduce gasoline volatility from 11.5 to 10 pounds a square inch between July and September of this year. The volatility level would drop to nine pounds a square inch for summer months beginning in 1989.

Representatives of Mobil Research & Development Corp., Mobil Oil and Sun Oil Co. told a hearing the gasoline formula changes may harm some cars and are too severe to expect offsetting air quality improvements.
