Changes to 40 CFR Part 136 Tables and Table Footnotes

04 April 2012

A number of changes have been made to the Tables and associated footnotes in 40 CFR Part 

136.3(a) between the proposal and the final rule. These changes are typographical errors, 

corrections or clarifications, and are listed below. 

In addition, the Office of the Federal Register requested that all of the references in Part 136.3(b) 

be reformatted per their incorporation by reference requirements, which then required a revision 

of the footnotes. Reformatting changes made for this purpose are not noted here. Because the 

method availability information can be found in Part 136.3(b), that redundant information has 

been deleted from the footnotes in Tables IA, IB, IC, ID, IG and IH. A similar change will be 

made for Tables IE and IF in future rulemakings when changes to these tables are made. Lastly, 

all EPA methods can be found at our website 

http://water.epa.gov/scitech/methods/cwa/index.cfm.

Table IA

Line 4, Coliform (total), in presence of chlorine, number per 100 mL; MF2 with enrichment. 

Footnote 5 regarding the use of MPN methods for chlorinated wastewaters added. A 

typographical error deleted this footnote in previous rulemakings.

Line 5, E. coli, number per 100 mL21; MF2,6,7,8, single step. Footnote 5 regarding the use of 

MPN methods for chlorinated wastewaters was deleted because the footnote is not relevant to 

unchlorinated matrices. Correction.

Table IB

A number of Standard Methods lacked specifics about which letter was associated with the 

method, for example 3113 – 2004 should have been 3113 B-2004. This occurs in multiple 

lines throughout the table, all of which have been corrected. Correction and clarification.

Line 8, Beryllium–Total,4 mg/L; Colorimetric (aluminon). Previously Standard Method 3500-Be 

D was listed in the Standard Methods column for this parameter. However, the listing should 

have been for 3500-Be without the "D" since that does not exist. The current Standard 

Methods method for this parameter is in footnote 61. See next item regarding footnote 61. 

Typographical error.

Line 8, Beryllium–Total,4 mg/L; Colorimetric (aluminon). The reference to footnote 61 was 

moved from the "other" column to the Standard Methods column, since it refers to Standard 

Methods 3500-Be. Typographical error.

Line 26, Gold–Total,4 mg/L; AA furnace. EPA method version corrected from "EPA Method 

231.2 (Rev 1978)1" to "EPA Method 231.2 (Issued 1978)1". "Revision" should have been 

"Issued," typographical error.

Line 27, Hardness–Total, as CaCO3, mg/L; Titrimetric (EDTA). AOAC method number 

corrected from 973.5 2B to 973.52B. Space between 5 and 2 deleted, typographical error.
2

Line 31, Kjeldahl Nitrogen5–Total, (as N), mg/L; Manual digestion20 and distillation or gas 

diffusion, followed by any of the following:. Standard Methods method number corrected 

from 4500-Norg B-1997 to 4500Norg B-1997. "Org" should have been subscript, 

typographical error.

Line 31, Kjeldahl Nitrogen5

–Total, (as N), mg/L; Semi-automated block digestor colorimetric 

(distillation not required). Standard Methods method number corrected from 4500-Norg D1997 to 4500Norg D-1997. "Org" should have been subscript, typographical error.

Line 35, Mercury–Total4, mg/L; Cold vapor, Automated. EPA Method availability corrected 

from "EPA Method 245.2 (Issued 1974)" to "EPA Method 245.2 (Issued 1974)1

". The 

method is not found in the EPA documents listed in footnote 52, which addresses the entire 

column of EPA methods. Rather, the method is available in the EPA document listed in 

footnote 1. Added correct footnote for method, typographical error.

Line 35, Mercury–Total4, mg/L; ICP/AES and ICP/MS. These proposed methodologies were 

deleted because the detection limit was too high. Correction.

Line 38, Nitrate (as N), mg/L; Colorimetric (Brucine sulfate). EPA method corrected from 

"352.11

" to "352.1 (Issued 1971)1". Issue date added, typographical error.

Line 42, Organic carbon–Total (TOC), mg/L; Combustion. Comma moved from "973.47,3 p. 

1424" to "973.473

, p. 1424". Comma moved from before to after the "3" superscript, 

typographical error.

Line 42, Organic carbon–Total (TOC), mg/L; Heated persulfate or UV persulfate oxidation. 

Comma moved from "973.47,3 p. 1424" to "973.473, p. 1424". Comma moved from before to 

after the "3" superscript, typographical error.

Line 46, Oxygen, dissolved, mg/L; Winkler (Azide modification). AOAC method number 

corrected from 973.4 5B to 973.45B. Space between 4 and 5 deleted, typographical error.

Line 50, Phosphorus–Total, mg/L; Persulfate digestion20 followed by any of the following. The 

word "Persulfate" was removed because not all of the methods contain persulfate digestion. 

Correction.

Line 51, Platinum–Total,4 mg/L; AA furnace. EPA method corrected from "255.21" to "255.2 

(Issued 1978)1". Issue date added, clarification.

Line 57, Residue–Volatile, mg/L; Gravimetric, 550°. EPA method corrected from "160.41

" to 

"160.4 (Issued 1971)

1

". Issue date added, clarification.

Line 58, Rhodium–Total,4 mg/L; AA furnace. EPA method corrected from "265.21

" to "265.2 

(Issued 1978)1

". Issue date added, clarification.

Line 70, Thallium–Total,4 mg/L, ICP/AES. Added EPA Method 200.5 to this methodology 

because thallium is covered by this method. Oversight and correction.

Table IB footnotes

Footnote 19. Method title corrected from "Copper, Biocinchoinate Method, Method 8506..." to 

"Method 8506, Biocinchoninate Method for Copper...." Word Biocinchoninate was missing 

the second "n", typographical error.

Footnote 24. Method title corrected from "Methods for Analysis of Organic Substances in 

Water." to "Methods for Analysis of Organic Substances in Water and Fluvial Sediments." 

Words "and Fluvial Sediments" added to method title, per method, typographical error.

Footnote 24. Book name for location of method corrected from "...Water-Resources 

Investigation... (1972 Revised 1987) p. 14." to "...Water-Resources Investigations...(1972 

Revised 1987." The word investigation should have been plural, typographical error.

Footnote 43. Publication date corrected from September 2002 to August 2002. Typographical 

error.

Footnote 43. EPA document number for Method 1631 corrected from EPA-R-02-024 to EPA-R02-019. The former is for EPA Method 1604 for total coliforms and E. coli, rather than for 

EPA Method 1631 for Mercury in Water by Oxidation, Purge and Trap, and Cold Vapor 

Atomic Fluorescence Spectrometry. Incorrect EPA document number, typographical error.

Footnote 43. EPA Method 1669 is no longer draft – no changes have been made to the method 

since it was published in 2001. The second sentence was corrected from "...described in 

EPA's draft Method 1669..." to "...described in EPA's Method 1669...", clarification.

Footnote 45. Method title corrected from "Methods of Analysis by the U.S. Geological Survey 

National Water Quality Laboratory–Determination of Ammonia Plus Organic Nitrogen by a 

Kjeldahl Digestion Method" to "Methods of Analysis by the U.S. Geological Survey

a Kjeldahl Digestion Method and an Automated Photometric Finish that Includes Digest 

Cleanup by Gas Diffusion." Words "and an Automated Photometric Finish that Includes 

Digest Cleanup by Gas Diffusion" added to method title, per method, typographical error.

Footnote 51. Method title corrected from "Methods of Analysis by the U.S. Geological 

Survey...and Fluvial Sediment." to "Methods of Analysis by the U.S. Geological 

Survey...and Fluvial Sediments." The word sediment should have been plural, typographical 

error.

Footnote 57. Sentence changed from "When using sulfide removal...Method 335.4, 

reconstitute...." to "When using sulfide removal...EPA Method 335.4-1, reconstitute...." 

Added revision number and clarification that method is an EPA method.

Table IC

Line 1, Acenaphthene. ASTM method number corrected from "D4657-92 (99)" to "D4657-92 

(98)". The revision year should have been 1998 rather than 1999, typographical error. This 

error also applies to this method in the following 15 lines:

Line 2, Acenaphthylene

Line 5, Anthracene

Line 8, Benzo(a)anthracene

Line 9, Benzo(a)pyrene

and at http://water.epa.gov/scitech/methods/cwa/index.cfm." Clarification.

Table ID

Line 27, Dicofol. Standard Methods 6630 B-2000 was deleted because dicofol is not on the 

analyte list for the method. Correction.

Line 42, Isodrin. Standard Methods 6630 B-00 and 6630 C-00 were deleted because isodrin is 

not on the analyte list for either method. Correction.

Line 44, Malathion; GC. Standard Methods 6630 C was replaced by Standard Methods 6630 B2000 in the proposal. Standard Methods 6630 C was deleted because malathion is not on the 

analyte list for the method. Correction.

Line 52, Parathion methyl; GC. Standard Methods 6630 C was replaced by Standard Methods 

6630 B-2000 in the proposal. Standard Methods 6630 C was deleted because parathion 

methyl is not on the analyte list for the method. Correction.

Line 53, Parathion ethyl; GC. Standard Methods 6630 C was replaced by Standard Methods 

6630 B-2000 in the proposal. Standard Methods 6630 C was deleted because parathion ethyl 

is not on the analyte list for the method. Correction.

Line 55, Perthane. Standard Methods 6630 B & C was replaced by Standard Methods 6630 B2000 in the proposal. However, neither of these methods contain perthane as an analyte for 

the methods, hence both Standard Methods 6630 B-2000 and C have been deleted. 

Correction.
