Toxic Cement Dust

Cement dust may contain trace amounts of hazardous air pollutants that include TOXIC heavy metals such as mercury, arsenic and lead. What is the source and quality of the cement to be delivered? Are there alternate production source... of lessor quality... possibly shipped from outside the USA? Does it contain TOXINS? Is the cement dust free of carcinogens? Who will assure the public that their health is not at risk? Let's not waste until AFTER health issues develop before we find the truth!

It has been reported that in 1992, the EPA became aware that 20% of cement dust tested positive for radioactive plutonium-238 and -239 and cesium-137, potentially causing numerous types of cancers.

Toxic Fly Ash

This project proposes to use [TOXIC] fly ash. Why? Because it is a good substitute for [portland] cement... and it is CHEAP.

Fly ash is cheap because it is a waste by-product. Fly ash often contains a wide variety of heavy metals and other toxic contaminates. Who is responsible for assuring the public's health. Who is going to regulate and oversee the fly ash manufacturing process [and what waste products might be "added"] at it's source?

One fly ash contaminate that, if found in very small qualties, can cause numerous health problems and is a carcinogen known to cause lung cancer. It is chrome 6, also called hex chrome.

Another contaminate, if found in fly ash, is the toxic metal mercury. It has been stated that only 1/70th of a teaspoon of mercury [about the amount in a medical thermometer] will contaminate a 20 acre body of water and make all fish within it toxic to humans.

Again, where is this fly ash going to originate from? Asia? South America? What safeguards are present during the manufacture of the fly ash that is then shipped to the proposed Silverton plant?

Who will assure the safety of the public in Silverton? Not the DEQ. They are not going to do any toxicity testing... they are only going to determine the weight of particular dust sizes... once every 1 to 5 years [maybe]... Whoopee!!
