Studies and health experts' opinions gathered by the Division of Air and Hazardous Materials indicate a possible need for stronger controls on nitrogen dioxide emission from the plant than the division had previously considered necessary. Donald Squires, an air pollution control engineer in the division, said yesterday...
There has been some concern, in the department as well as among some residents of Boston's Mission Hill neighborhood, about the plant's expected levels of emission of nitrogen oxides...
...planners did not provide concessions that would limit the plant's emissions. Officials in the state Division of Air and Hazardous Materials should be commended for their extended efforts to overhaul the plant's design and to exact an agreement from Harvard to restrict the allowed emission level of nitrogen dioxide, a pollutant that can irritate the respiratory system...
...diesel engines needed to produce electricity will also be sources of nitrogen dioxide, and unless Harvard representatives can show that the plant will not add excessively to the atmospheric level of the gas in the area, the environmental quality department will probably require elimination of the diesel generators from the project, entailing a major redesign...
AUTO EMISSIONS. Under the 1970 act, automakers had until the 1975 model year to eliminate 90% of all hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx). Detroit has cut harmful emissions considerably: this year's General Motors cars, for example, produce 90% less HC and 83% less CO than those of the early 1960s. But faced with the difficulty of reducing emissions while also cutting gasoline consumption, the automakers persuaded the Environmental Protection Agency to extend the deadline to 1978. Now they want still more time and less stringent standards. The Senate is willing to give them until...
