#  Expedited Approval of Alternative Test Procedures for the Analysis of Contaminants Under the Safe Drinking Water Act; Analysis and Sampling Procedures

**Correction**

In rule document E9-27044 beginning on page 57908 in the issue of November 10, 2009, make the following correction:

1. On page 57915, the second table should appear as follows:

| Organism | Methodology | SM 20th | SM 21st | SM online | Other |
| --- | --- | --- | --- | --- | --- |
|  | ONPG-MUG Test | 9223 B | 9223 B | 9223 B-97 |  |
|  |  |  |  |  | Modified Colitag |

2. On page 57917, the first table should appear as follows:

| Contaminant | Methodology | EPA method | ASTM | SM 21st edition |
| --- | --- | --- | --- | --- |
|  |  |  |  |  |
| *         *         *         *         *         * |  |  |  |  |
| HAA5 | LLE (diazomethane)/GC/ECD |  |  | 6251 B |
|  | Ion Chromatography Electrospray Ionization Tandem Mass Spectrometry (IC-ESI-MS/MS) | 557 |  |  |
| Bromate | Two-Dimensional Ion Chromatography (IC) | 302.0 |  |  |
|  | Ion Chromatography Electrospray Ionization Tandem Mass Spectrometry (IC-ESI-MS/MS) | 557 |  |  |
|  | Chemically Suppressed Ion Chromatography |  | D 6581-08 A |  |
|  | Electrolytically Suppressed Ion Chromatography |  | D 6581-08 B |  |
| Chlorite | Chemically Suppressed Ion Chromatography |  | D 6581-08 A |  |
|  | Electrolytically Suppressed Ion Chromatography |  | D 6581-08 B |  |

3. On page 57917, the fourth table heading, Alternative Testing Methods With MRL > 0.0010 mg/L for Monitoring Listed at **40 CFR 141.132(b)(3)(ii)(B)** should read Alternative Testing Methods With MRL ≤ 0.0010 mg/L for Monitoring Listed at **40 CFR 141.132(b)(3)(ii)(B)** .

4. On page 57918, the table should appear as follows:
