I have been hearing a lot of different things about this stuff.
1) it's proper name is "fly ash" not rock ash.
2) it is not considered toxic under the Bevill Amendment of the EPA Act of 1970
3) it is considered to be a high volume-low toxicity waste
4) it contains probably in the neighborhood of 100 ppm of Pb (lead) which will leach out as a result of acid rain-which does not exist in the DR
5) it contains calcium carbonate, calcium aluminate, some ferrous materials and silicates
6) it is used in cement is the United States. In fact 60% of cement poured in the US uses Fly Ash.
-A lot of the composition of fly ash depends on the coal used to produce energy.
-The amount of fly ash in Manzanillo has been calculated to be less than 10,000 tons
-It was originally brought in to set the base for a container parking lot.
-The coal fired units at Itabo and Barahona: Where does their fly ash go? Apparently, according to my sources, it is used by the cement factories of the DR
Somehow, I am getting the feeling that this may well be a tempest in a teapot, and the result of savvy use of press and environmental worries in a nearly defenseless (environmentally speaking, that is, nation. And one hell of a government move to get money (US$80 million = RD$2.5 billion) out of AES?? Or let a juicy contract to someone, a contract bartered by certain government employees for, say, 10% of the deal? US$13 million x 10% = US$1.3 million into someone's pocket?
I don't know..this stinks.
