This approval is for completion of UCMR2 only. Before this ICR can be used to authorize collection of information related to UCMR3, EPA will need to submit a revision (or new ICR) that reflects the requirements and burden associated with the final UCMR3 program.

The Safe Drinking Water Act (SDWA), as amended in 1996, directs EPA to establish criteria for a program to monitor not more than 30 unregulated contaminants every five years. EPA published the first group of contaminants in the Unregulated Contaminant Monitoring Regulation (i.e., UCMR 1), which established a revised approach for UCMR implementation, in the Federal Register dated September 17, 1999, (64 FR 50556). EPA published the second group of contaminants in UCMR 2, in the Federal Register dated January 4, 2007, (72 FR 367). This regulation met the SDWA requirement by identifying 25 new priority contaminants to be monitored during the UCMR 2 cycle of 2007-2011.
Under UCMR 2, Assessment Monitoring uses more common analytical method technologies used by drinking water laboratories. All public water systems (PWSs) serving more than 10,000 people, and 800 representative PWSs serving fewer than 10,001 people are required to monitor for the 10 "List 1" contaminants during a 12-month period between January 2008-December 2010. Screening Survey monitoring uses more specialized analytical method technologies not as widely used by drinking water laboratories. All PWSs serving more than 100,000 people, 320 representative PWSs serving 10,001-100,000 people, and 480 representative PWSs serving fewer than 10,001 people are required to monitor for the 15 "List 2" contaminants during a 12-month period between January 2008-December 2010.
