Class A or B biosolids?

There has been some confusion as to whether Bastrop would be blessed with Class A or Class B biosolids. So that was the second question posed to Mr. Sierant. Here is his detailed response:

To answer your questions below, the permit application is to land apply Class B biosolids from the City of Austin’s Hornsby Bend facility. Class B biosolids is essentially Wastewater Treatment Plant Sludge that may or may not be combined with Water Treatment Plant Sludge (WTP), which is the river mud from the treatment of drinking water. In the application, Denali has also listed WTP sludge to be land applied although a particular WTP source is not listed in the application, (i.e., City of Austin as the source for the wastewater treatment sludge). If the permit is issued, a WTP source can be added and approved in writing by the TCEQ if the sludge meets requirements for land application.

Since Dillo Dirt is a type of biosolids that meets the quality requirements considered by EPA and State standards for marketing and distribution (Class A), a permit like this proposed one is not needed. That would be to say that every person in the Austin metropolitan area that buys a bag of Dillo Dirt from Home Depot or Lowe’s or any other hardware store and puts it on their lawn would need a permit like this one. So, even though this proposed permit is for Class B biosolid land application, Denali can land apply Class A material in addition to Class B at the site since Class A material by itself does not need a permit to be land applied.

To clarify what type of sludge Denali plans to land apply at the site, Page 11, Section l. of the application has checkboxes next to each type of waste to be applied (see attachment). You will see that Wastewater Treatment Plant Sludge and Water Treatment Plant Sludge have been checked.

The rules prohibit land application of material coming off of a landfill, a grit or grease trap processing facility, car wash facility, chemical toilet waste, industrial waste, medical waste or, of course HAZARDOUS WASTE

You’ve gotta love the irony in that last paragraph. It points to the complete denial from the EPA down that this toxic sludge IS hazardous waste!!
