TRI Reporting

We do sulfuric acid anodizing on aluminum at our facility. I just finished doing calculations on the "manufacture" of nitrate compounds by neutralization in our wastewater treatment system. Because the only nitric acid we use is in the desmut compound we use, we were well under the 25,000 lb. limit for TRI reporting.

Are there any other compounds we could be generating during the neutralization of our wastewater that would cause problems with the EPA and their TRI report ? For example, any problems with aluminum or sulphates ?

You might try going to this site: www.epa.gov/triinter/report.htm <--Ed. note: Sorry readers, this link no longer works.

One of the things this highlighted in my search was coincidental manufacture of nitrates, etc., so it might give you what you're looking for. Good Luck!
