Abstract
This document covers both update of the SWTR list and the compliance technologies identified for the Total Coliform Rule (TCR). These have been grouped into one publication as they both address microbial contaminants and their indicators in drinking water. 3 The list of compliance technologies for the TCR is one of the lists required by Section 1412(b)(4)(E)(iii) of the SDWA. EPA met both the second and third of the short-term goals in August 1998. A Federal Register notice dated August 6, 1998 published the list of compliance technologies that systems can use to comply with all of the other NPDWRs and the findings concerning variance technologies for the contaminants regulated before 1996. EPA did not, at that time, list any variance technologies for contaminants regulated before 1996. Guidance manuals were developed to provide more detail on each of these lists. A document entitled "Small System Compliance Technology List for the Non-Microbial Contaminants Regulated Before 1996" (EPA, 1998c) provides more detail on the list of compliance technologies for the non-microbial contaminants regulated before 1996. The current document has been prepared to describe the procedures that were used to make the determination, at this time, that there would be no variance technologies for contaminants regulated before 1996.
