If two plants draw from a single surface water intake, can the plants share one source water sample or must each plant collect its own sample?

Yes they may share a sample, but the state must approve one set of monitoring results to be used for both plants.  The system should indicate they plan to do this when preparing their sampling schedule.

• If only one site exceeds the LRAA, do we need to notify everyone in the City, or just those in the affected area?
• The "Amount Detected" that is reported in the CCR is based on the Running Annual Averages that are used for compliance after each quarter. A system that was complying with Stage 1 will have one or more quarters of RAAs to compare for this value. However, systems that have NOT had to comply with Stage 1 will have only Stage 2 data and there will be no compliance calculations in 2012. DOES THIS MEAN THE "AMOUNT DETECTED" FOR THESE SYSTEMS WILL BE "N/A"? I believe this is what we did when these systems were doing their IDSEs.
• If the main wholesale water system gets a 2-year extension, does the consecutive system also get 2-year extension?
