Not so fast. In 2007 the solid wastes from these tiny plants was 54,000 metric tons. I say tiny in reference to their output, rarely over 50MW. Their pysical size however is roughly equal to a 250-300MW gas fired steam plant.
The wastes include ,If I remember correctly 4 radionucleides in the total of 80 or so hazardous materials. I worked in the Brawley field around 2009-2010 and they had at least 50 tractors and trailers hauling the wastes to landfills. The visual impact is OK, y'see, if it's someone elses problem.
