There is an EPA 8015D (Revision 2003) and also an EPA 8015C (Revision 2007). Which of these two methods is the latest/updated version?
Method 8015C is an official, approved method that was formally included in the SW‐846 via a Federal Register Notice whereas Method 8015D is posted on the RCRA Methods website, considered as “validated” for public use and comment to be later finalized. The process for publishing validated methods for inclusion in SW‐846 takes time, and the two methods (i.e., Methods 8015C and 8015D) took slightly different paths before they were published online, resulting in a later publication date for Method 8015C. The differences between the methods are minimal. Therefore, they should yield similar results.
