Acronyms: AL = action level; CWS = community water system; NTNCWS = non-transient non-community water system; PWS = public water system; LSLR = lead service line replacement.
Notes:
[1] Under the previous rule, these activities could stop after the system no longer has a lead ALE for two consecutive 6-month monitoring periods.
[2] As previously discussed in Section B.5.3.2, in Arkansas, Louisiana, Mississippi, Missouri, and South Carolina the state pays for the cost of bottles and shipping and conducting the analysis for samples following LSLR. Thus, the state will incur the burden and cost for these activities.
Primacy Agency Lead Public Education and Outreach
Under the previous rule, Primacy Agencies incurred oversight burden associated with PE that needed to be conducted when a system exceeded the lead AL. These oversight activities are provided in Exhibit B-55. The exhibit provides the unit burden for each activity. The third column provides the corresponding SafeWater LCR model data variable in red/italic font. The last column indicates whether or not the activity, unit burden or cost, the SafeWater LCR model data variable, and/or applicability are identical to those used for the LCRR, as described in Chapter 5, Section <IP_ADDRESS>. The assumptions that differ from the LCRR follow the exhibit. Those activities under the LCRR that pertain to new consumer notice requirements when a single sample exceeds 15 ug/L and enhanced outreach that is independent of lead 90th percentile levels do not apply to the previous rule and thus, are not discussed in this section. Refer to Chapter 5, Sections <IP_ADDRESS> and <IP_ADDRESS> for additional detail on these outreach requirements under the LCRR.

    Provide template and review revised lead language (hrs_ale_consult_js): As previously discussed in Section B.5.4, activity a), EPA revised the content requirements for PE that is required when a system exceeds the lead AL as part of the Short-Term Regulatory Revisions to the Lead and Copper Rule (USEPA, 2007b). As a simplifying assumption, EPA assumed all systems that are triggered into PE requirements under the previous rule will update their mandatory PE language although some systems would have already conducted this activity, which may overestimate costs. Under the LCRR, systems are required to further update their materials to include revised mandatory health effects language, and those that also have LSLs must include information about their LSLR program and opportunities to replace LSLs. Although the specific updates differ between the previous rule and LCRR, EPA assumed Primacy Agencies would incur the same burden under both rules to provide templates and review each system's revised PE mandatory language. Thus, EPA used the same data variable and input for this activity for both rules.
Exhibit B-56 shows the SafeWater LCR model cost estimation approach for Primacy Agency PE activities including additional cost inputs that are required to calculate these costs.

[3] The Primacy Agency will review certifications quarterly for CWSs. For modeling purposes, the Primacy Agency burden is estimated on an annual basis.

: Detailed Costs Results
Introduction
In this appendix EPA provides the detailed SafeWater LCR model results for each category of system size, water source, and type (i.e. CWS or NTNCWS). Section C.2 provides the system counts and impacted population. Section C.3 contains the output for the national annualized total rule costs at the 3 percent and 7 percent discount rates. Section C.`4 provides the national annualized sampling requirement costs at the 3 percent and 7 percent discount rates. The national annualized lead service line inventory and replacement requirement costs at the 3 percent and 7 percent discount rates are in Section C.5. Section C.6 provided the national annualized corrosion control technology requirement costs at the 3 percent and 7 percent discount rates. Section C.7 supplied the annualized incremental cost per water system. The results of the low and high cost scenarios are provided in each section.
