This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.
In rule document 01-59 beginning on page 2273 in the issue of Thursday, January 11, 2001, make the following corrections:
1. On page 2302, in Table 1.—Unregulated Contaminant Monitoring Reporting Requirements, item 15 should read as follows:
|15. Analytical Accuracy||Accuracy describes how close a result is to the true value measured through the use of spiked field samples. For purposes of unregulated contaminant monitoring, accuracy is defined as the percent recovery of the contaminant in the spiked matrix sample analyzed in the same analytical batch as the sample result being reported and calculated using:|
|% recovery = [(amt. found in spiked sample—amt. found in sample)/amt. spiked] × 100%.|
2. On page 2303, in Table 1.—Unregulated Contaminant Monitoring Regulation (1999) List, the entry for “Perchlorate” should read as follows:
|List 1—assessment monitoring chemical contaminants|
|1-contaminant||2-CAS registry number||3-analytical methods||4-minimum reporting level||5-sampling location||6-period during which monitoring to be completed|
|Perchlorate||14797-73-0||EPA Method 314.0 l||4 μg/L m||EPTDS f||2001-2003|
3. On page 2304, in the table titled “List 2—screening survey chemical contaminants”, the entry for “Terbufos” should read as follows:Start Printed Page 27216
|List 2—screening survey chemical contaminants|
|1-contaminant||2-CAS registry number||3-Analytical methods||4-Minimum reporting level||5-sampling location||6-Period during which monitoring to be completed|
|Terbufos||13071-79-9||EPA Method 526 a||0.5 μg/L f||EPTDS e||2001—Selected Systems serving ≤10,000 persons; 2002-Selected systems serving > 10,000 persons.|
In proposed rule document 01-10838 beginning on page 21710 in the issue of Tuesday, May 1, 2001, make the following corrections:
1. On page 21715, in the second column, in amendatory instruction 5.b., in the second line “all” should read “add”.
