Some small PWSs that do not have to monitor Cryptosporidium may also have to conduct inactivation profiling if their trihalomethane or haloacetic acid levels exceed certain limits. Most plants will already have existing benchmarks due to similar requirements under the IESWTR and LT1ESWTR. If they do not, they should be able to calculate benchmarks based on existing operational data collected as part of the Surface Water Treatment Rule requirements. Most of these plants need to maintain these data onsite, but do not need to report them. The burden for this is assumed to be negligible.

Plants that wish to make a major change to their disinfection process need to compile and submit their disinfection profile and benchmark to their States and consult with their States about the change. Only plants that are predicted to change technologies as a result of bin classification are assumed to submit their disinfection profile. The burden for this is estimated to be 4 hours per plant and is shown in Exhibits D. 25 through D. 27.

Reporting costs for small plants serving up to 500 people are based on the full technical rate ($ 24.96 per hour). For those plants serving more than 500 people, costs are based on an 80/ 20 percent split between technical and managerial labor rates ( the split was between $ 24.96 per hour and $ 44.91 per hour) ( BLS 2001).

Economic Analysis for the LT2ESWTR Proposal D 73 June 2003 Economic Analysis for the LT2ESWTR Proposal June 2003 D 74 D. 7 Future Monitoring for Bin Reclassification Six years after initial binning, systems will be required to undergo another round of monitoring to determine if their source water quality has changed, thus changing the required treatment. Lacking better information, EPA assumed that costs are the same as the costs for the initial monitoring round. The number of plants did change, however, as plants which achieved 5.5 log treatment to comply with the LT2ESWTR were omitted from the second round of monitoring.

D. 7.1 Future E. coli Monitoring Exhibits D. 31 through D. 33 show the future laboratory costs and labor for E. coli monitoring. The only changes from the original round are the number of plants sampling. The tables display costs for the three Cryptosporidium occurrence distributions for Alternatives A2 through A4.

Samples must be shipped overnight to meet 24 hour holding time requirements. Costs based on FedEx priority overnight rates for 10 L sample ( 22 LB) shipped in a 34 quart polyethylene cooler packed with wet ice, median cost for all zones. Samples generating a pellet volume of > 0.5 ml require multiple subsample processing at a cost of $ 140 each. During the ICR Supplemental Survey, approximately 27 percent of field samples required analysis of multiple subsamples, resulting in an additional per plant charge of $ 38 ($ 140 x 0.27).

Economic Analysis for the LT2ESWTR Proposal D 93 June 2003 Economic Analysis for the LT2ESWTR Proposal June 2003 D 94 D. 7.3 Future Monitoring Reporting Labor and cost of labor for future monitoring are assumed to be the same as for initial monitoring, although for future monitoring, all systems are expected to report their results to their Primacy Agencies rather than to EPA. The number of systems monitoring, however, will be lower than for initial monitoring, since some plants are expected to have implemented treatment that exempts them from future monitoring.

Costs associated with reporting would include the amount of time it takes for a plant to gather monitoring information and submit it to its State/ Primacy Agency for review. Since the exact schedule of reporting to States is not set in the rule, there may be some variation in reporting effort from State to State. For this analysis, 0.25 hours per sample ( 6.5 hours for small plants and 6 hours for medium and large systems) is used to estimate costs.

Reporting costs for small plants serving up to 500 people are based on the full technical rate ($ 24.96 per hour). For those plants serving more than 500 people, costs are based on an 80/ 20 percent split between technical and managerial labor rates ( the split was between $ 24.96 per hour and $ 44.91 per hour) ( BLS 2001). The costs of reporting are presented in Exhibit D. 37 to D. 39 for Alternatives A2 to A4, respectively. The number of systems reporting also varies with the use of the ICR, ICRSSM, and ICRSSL occurrence distributions. This is because future monitoring and reporting depends on the number of systems placed in different treatment bins, and this is a function of the occurrence distribution.

The decrease in burden for small plants that report E. coli but are exempt from Cryptosporidium monitoring is also assumed to be negligible.

( B) For plants serving up to 500 people, the full technical rate ($ 24.96/ hour) was applied. For plants serving more than 500 people, costs are based on an 80%/ 20% split between technical and managerial ($ 44.91/ hour) rates. Rates are based on Bureau of Labor Statistics data.
