This rule makes minor changes to clarify and correct EPA's Drinking Water regulations. This rule clarifies typographical errors, inadvertent omissions, editorial errors, and outdated language in the final Long Term 1 Enhanced Surface Water Treatment Rule (LT1ESWTR), the Surface Water Treatment Rule, and other rules. In addition to these clarifications, EPA is adding optional monitoring for disinfection profiling and an earlier compliance date for some requirements in the LT1ESWTR, and a detection limit for the Uranium Methods.
Also, EPA is reinstating text that was inadvertently dropped from the Lead and Copper Rule which listed the facilities that must be sent public education brochures by a public water system that has exceeded the action level for lead or copper.
This final rule is effective on July 29, 2004, except for the amendment to § 141.85(c)(2)(iii) which is effective June 29, 2004. For purposes of judicial review, this final rule is promulgated as of 1 p.m., eastern time on July 13, 2004, as provided in 40 CFR 23.7.

Entities potentially regulated by this action are public water systems (PWS). The following table provides examples of the regulated entities under this rule. A public water system, as defined by section 1401 of the Safe Drinking Water Act (SDWA), is “a system for the provision to the public of water for human consumption through pipes or other constructed conveyances, if such system has at least fifteen service connections or regularly serves at least twenty-five individuals.” EPA defines “regularly served” as receiving water from the system 60 or more days per year. Categories and entities potentially regulated by this action include the following:
State, Tribal and Local Government State, tribal or local government-owned/operated water supply systems using ground water, surface water or mixed ground water and surface water.
Federal Government Federally owned/operated community water supply systems using ground water, surface water or mixed ground water and surface water.
Industry Privately owned/operated community water supply systems using ground water, surface water or mixed ground water and surface water.
This table is not intended to be exhaustive, but rather provides a guide for readers regarding entities likely to be regulated by this action. This table lists the types of entities that EPA is now aware could potentially be regulated by this action. Other types of entities not listed in the table could also be regulated. To determine whether your facility is regulated by this action, you should carefully examine the applicability criteria in §§ 141.2 and 141.3 of title 40 of the Code of Federal Regulations. If you have questions regarding the applicability of this action to a particular entity, consult the person listed in the preceding FOR FURTHER INFORMATION CONTACT section.
EPA is promulgating today, all of the changes and clarifications proposed on March 2, 2004 (69 FR 9781), with the exception of two proposed clarifications discussed in section F concerning calibration of turbiditimeters. Each clarification and change promulgated today is discussed under the heading of the drinking water rule that it amends (e.g., LT1ESWTR). EPA is also promulgating today an additional clarification, which was not in the March 2, 2004, Minor Corrections and Clarification to Drinking Water Regulations proposal. This clarification is discussed in section III.
In addition to clarifications of typographical and editorial errors, EPA is revising the LT1ESWTR to add optional monitoring for disinfection profiling and an earlier compliance date for some requirements in that rule. EPA is also promulgating a detection limit for the uranium methods. These three changes are discussed first.
The final LT1ESWTR was published on January 14, 2002 (67 FR 1812). In § 141.502 of the LT1ESWTR, EPA directed PWSs to “comply with these requirements in this subpart beginning January 14, 2005, except where otherwise noted.” Today's rule changes the compliance date from January 14, 2005, to January 1, 2005, in § 141.502 as well as in endnote 8 of Subpart Q, Appendix B. EPA's reasons for moving the compliance date forward by two weeks are set forth in the preamble to the proposed rule at 69 FR 9782.
EPA is also changing the compliance date in two additional sections, §§ 141.73(a)(4) and 141.170(d), which reference the January 14, 2005, date. These two citations should have been included in the March 2, 2004, proposal.
By changing § 141.502, the following 12 requirements will have a compliance deadline of January 1, 2005, instead of January 14, 2005: §§ 141.520, 141.521, 141.522, 141.550, 141.551, 141.552, 141.553, 141.560, 141.561, 141.562, 141.563, and 141.564. July 1, 2003 (or January 1, 2004, for systems serving fewer than 500 persons), remains the compliance date for §§ 141.530-141.536. March 15, 2002, remains the compliance date for § 141.511.
In addition to changing the compliance date, EPA is adding a sentence to § 141.531 to clarify that States may approve a more representative total trihalomethanes (TTHM) and haloacetic acids (five) (HAA5) data set (optional monitoring) to avoid the disinfection profile monitoring required in § 141.530. EPA's intent was to allow this flexibility in the final LT1ESWTR rule (67 FR 1820, January 14, 2002). EPA had failed to make this flexibility explicit in that regulation.
The December 7, 2000, final Radionuclides Rule (65 FR 76708) included a detection limit for gross alpha, radium-226 and radium-228, and reserved a place for a uranium detection limit in Table B at § 141.25(c)(1). In today's action, EPA is amending Table B at § 141.25(c)(1) to add a detection limit of 1 μg/L for uranium. Establishing a uranium detection limit permits States the flexibility to substantially reduce the number of compliance samples and the frequency of repeat monitoring for uranium.
In addition to amending the detection limit for uranium, EPA is making two clarifications to the final Radionuclide Rule (December 7, 2000, 65 FR 76708). In § 141.26(b)(2)(iv), EPA is adding “screening level” to the first sentence. (Note also, that the second “beta” in this sentence is a typographical error, and under today's rule is being removed.) Similarly, EPA is clarifying in § 141.26(b)(5), that there are two screening levels by adding the word “appropriate” to the first sentence so that it reads “* * * exceeds the appropriate screening level * * *.” In addition, in the text that proposed to revise § 141.26(b)(5), we inadvertently referenced a nonexistent Table E, “or Table E in 141.66(d)”—this reference is deleted in this final rule.
In § 141.26(b)(6), EPA is revising the citation “(b)(1)(ii)” to read “(b)(1)(i),” and is revising citation “(b)(2)(i)” to read “(b)(2)(iv).” These were typographical errors and should have been (b)(1)(i) and (b)(2)(iv), which refer to meeting the screening level requirements until the system meets the requirements for reduced monitoring.
In addition to changing the date in § 141.502 to reduce monitoring burden as well as to allow States to approve alternative data sets for optional monitoring in § 141.531, EPA is clarifying typographical errors in the final LT1ESWTR. In Subpart Q Appendix B, in endnotes 4 and 8, the year of publication for the Long Term 1 Enhanced Surface Water Treatment Rule is incorrectly identified as 2001 when it should be 2002. Also in endnote 4, the word “monthly” is misspelled. In § 141.530 EPA is removing the grammatically incorrect, plural “s” from “systems” in the sentence “If you are a subpart H community or non-transient non-community water systems which serves fewer * * *”.
Two typographical errors are being corrected in § 141.534. In the introductory paragraph for § 141.534, EPA inadvertently omitted a reference to § 141.74(b)(3)(v), which provides tables for determining the appropriate CT99.9 value to calculate the inactivation ratio. EPA is changing the introductory paragraph of § 141.534 to: “Use the tables in § 141.74(b)(3)(v) to determine the appropriate CT99.9 value. Calculate the total inactivation ratio as follows, and multiply the value by 3.0 to determine log inactivation of Giardia lamblia:”
In the table in § 141.534(a)(2), EPA is changing the “3” to “Σ” in the CT calculation formula. EPA inadvertently changed the “Σ” to a “3” during a text file conversion.
In § 141.551(a)(2), EPA is adding a “t” to the “no” in “A value determined by the State (no to exceed 1 NTU) * * *”. In § 141.551(b)(2), EPA is adding the word “Filtration” to the phrase “All other ‘Alternative’ ” so that it matches related language in § 141.551(a)(2).
EPA is deleting the last sentence in the second column in the table in § 141.563(b), because it is redundant. Also in the same table in § 141.563(c), the first column contains a typographical error. The acronym “BTU” will read “NTU” (Nephelometric Turbidity Units).
In the table in § 141.570(b)(2), EPA is adding the phrase: “and the cause (if known) for the exceedance(s)” to the description of information to report under § 141.570(b)(2). As a result, the entire paragraph will read: “The filter Start Printed Page 38852number(s), corresponding date(s), and the turbidity value(s) which exceeded 1.0 NTU during the month, and the cause (if known) for the exceedance(s), but only if 2 consecutive measurements exceeded 1.0 NTU.”
This action redesignates the LT1ESWTR special primacy text as § 142.16(p). In addition, EPA is revising a citation in § 142.16 (p)(2)(ii) to “141.536” to read “141.535.” This was a typographical error and should have been “141.535,” which refers to calculating inactivation.
The Stage 1 Disinfectants and Disinfection Byproducts Rule was promulgated on December 16, 1998 (63 FR 69390). This rule required systems to measure and report, among other things, violations of maximum residual disinfectant levels (MRDLs), see § 141.134(c)(1)(iv) (see 63 FR 69422 and 69472). However, EPA failed to add compliance with the applicable MRDL to the compliance requirements in § 141.133(a)(3). EPA is correcting this, and the language in § 141.133(a)(3) now reads “If, during the first year of monitoring under § 141.132, any individual quarter's average will cause the running annual average of that system to exceed the MCL for total trihalomethanes, haloacetic acids (five), or bromate; or the MRDL for chlorine or chloramine, the system is out of compliance at the end of that quarter.” The burden for this requirement was already accounted for in the approved Information Collection Request No. 1895.02.
Also, in the final Stage 1 Disinfectants and Disinfection Byproducts Rule, EPA incorrectly cited in § 142.14(d)(12)(iv) and § 142.14(d)(13) a reference to § 142.16(f). The reference for both sections is now being revised to read § 142.16(h)(2) and § 142.16(h)(5) respectively.
The Surface Water Treatment Rule (SWTR) was promulgated on June 29, 1989 (54 FR 27486). In that final rule, EPA incorrectly cited in § 141.74(b)(4)(ii) a reference to § 142.72(a). This citation is being corrected to read § 141.72(a).
Today's rule does not include the proposed clarifications (March 2, 2004, 69 FR 9784) concerning the calibration of turbiditimeters in § 141.174(a) (Interim Enhanced Surface Water Treatment Rule (IESWTR)) and in § 141.560(b) (LT1ESWTR). EPA is deferring a decision on this clarification until additional information provided in a public comment can be evaluated.
EPA is changing all citations to § 141.74(a)(3) or (4) to § 141.74(a)(1), and all citations to § 141.74(a)(5) to § 141.74(a)(2) to reflect revisions to the SWTR as described in the proposal.

The Filter Backwash Recycling Rule (FBRR) was promulgated on June 8, 2001 (66 FR 31086). EPA inadvertently provided incomplete citations in subpart Q, Appendix A of the Public Notification rule for the FBRR violations. In entry I.A.(8) of 40 CFR part 141, subpart Q, Appendix A, EPA is adding a “(c)” to the “MCL/MRDL/TT violations Citation” column of § 141.76; and, in the “Monitoring & testing procedure violations Citation” column EPA has added “(b), (d)” to § 141.76.
The FBRR preamble (66 FR 31086, 31094) explicitly states that violations of the recordkeeping and reporting portions of this treatment technique trigger public notification (PN) obligations under 40 CFR part 141, subpart Q. EPA is clarifying the PN rule by striking the reference to reporting violations in Appendix A, endnote 1, and explicitly adding §§ 141.76(b), (c) and (d) to the list of categories requiring reporting in Appendix A (previous reference was to the entire § 141.76).
In a November 1995 final rule (60 FR 57132), the Food and Drug Administration (FDA) moved their standards of quality for bottled water from 21 CFR 103.35 to 21 CFR 165.110. EPA is correcting a reference in our regulations in § 142.62(g)(2) to reflect the updated citation of these FDA regulations.
The Information Collection Rule (ICR) was promulgated on May 14, 1996 (61 FR 24354). The requirements promulgated in the ICR expired on December 31, 2000. As a result, the ICR requirements (referred to as subpart M—Information Collection Requirements (ICRs) for Public Water Systems) were removed from the Code of Federal Regulations in 2001. However, there were remaining references to the data collected as a result of the ICR in other sections of part 141 that refer to “subpart M.” EPA is deleting the phrase “or subpart M of this part” from § 141.132(a)(5). EPA is not deleting or revising the other references to subpart M because the data collected under the ICR are still being used.
In the final Phase V Rule (July 17, 1992, 57 FR 31776), EPA published a list of Best Available Technologies (BATs) for cyanide, see § 141.62(c). EPA is making the list more specific as to the type of chlorination (“alkaline chlorination”).
In this final version of the rule, EPA is reinstating the list of the facilities that must be sent public education brochures by a public water system that has exceeded the action level for lead or copper. This list was included in the final Lead and Copper Rule, in § 141.85(c)(2)(iii) (June 7, 1991, 56 FR 26460; 26555) and published in the Code of Federal Regulations (CFR) from 1991 to 1999. However, a technical drafting error in the way in which EPA drafted its language of amendment for revisions to the LCR in 2000 caused the Office of Federal Register to delete this text from the 2001 edition of the CFR (January 12, 2000, 65 FR 1950, 2007). Thus, the current CFR text contains only a requirement to deliver public education materials “to facilities and organizations, including the following:” with no text following the colon. To remedy this, EPA is reinstating the missing text, specifically subparagraphs (A) through (G). Section 141.85(c)(2)(iii) will once again read as follows:
(iii) Deliver pamphlets and/or brochures that contain the public education materials in paragraphs (a)(1)(ii) and (a)(1)(iv) of this section to Start Printed Page 38853facilities and organizations, including the following:
(A) Public schools, and/or local school boards;
(B) City or county health department;
(C) Women, Infants, and Children and/or Head Start Program(s) whenever available;
(D) Public and private hospitals and/or clinics;
(E) Pediatricians;
(F) Family planning clinics; and
(G) Local welfare agencies.
Section 553 of the Administrative Procedure Act, 5 U.S.C. 553(b)(B), provides that, when an agency for good cause finds that notice and public procedure are impracticable, unnecessary, or contrary to the public interest, the agency may issue a rule without providing prior notice and an opportunity for public comment. EPA is reinstating the list of facilities that must be sent public education brochures by a public water system that has exceeded the action level for lead or copper. EPA has determined that there is “good cause” for making this rule change final without prior proposal and opportunity for comment because this list was the product of a prior notice-and-comment rulemaking, see (June 7, 1991, 56 FR 26502), it had appeared in the CFR for several years, the deletion was due solely to a technical drafting error in a subsequent rule, and the list is not controversial. Thus, additional notice and public comment is not necessary. EPA finds that this constitutes “good cause” under 5 U.S.C. 553(b)(B). For the same reasons, EPA is making this rule change effective upon publication. 5 U.S.C. 553(d)(3).
This action does not impose an information collection burden under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. This action modifies and clarifies existing regulations. It does not add monitoring, recordkeeping or reporting requirements.
Small entities are defined as: (1) A small business as defined by the Small Business Administration's (SBA) regulations at 13 CFR 121.201; (2) a small governmental jurisdiction that is a government of a city, county, town, school district or special district with a population of less than 50,000; and (3) a small organization that is any “not-for-profit enterprise which is independently owned and operated and is not dominant in its field.” However, the RFA also authorizes an agency to use alternative definitions for each category of small entity, “which are appropriate to the activities of the agency” after proposing the alternative definition(s) in the Federal Register and taking comment. 5 U.S.C. 601(3)-(5). In addition, to establish an alternative small business definition, agencies must consult with SBA's Chief Counsel for Advocacy.
For purposes of assessing the impacts of today's rule on small entities, EPA considered small entities to be public water systems serving 10,000 or fewer persons. This is the cut-off level specified by Congress in the 1996 Amendments to the Safe Drinking Water Act for small system flexibility provisions. As required by the RFA requirements, EPA proposed using this alternative definition in the Federal Register, (63 FR 7620, February 13, 1998), requested public comment, consulted with the Small Business Administration (SBA), and finalized in the alternative definition in the Consumer Confidence Reports regulation (63 FR 44511, August 19, 1998). As stated in that final rule, the alternative definition would be applied to this regulation as well.
The optional monitoring for disinfection profiling provides flexibility for PWSs complying with LT1ESWTR. The earlier compliance date will not increase the cost of complying with LT1ESWTR since the monitoring and reporting requirements are unchanged. By specifying the detection limit for uranium, States have the flexibility to waive some monitoring for PWSs with samples below the detection limit. This action will not add new requirements.
This final rule imposes no cost on any entities over and above those imposed by previously published drinking water rules. This action corrects and clarifies existing regulations.
After considering the economic impacts of today's final rule on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities. The small entities directly regulated by this final rule are public water systems serving 10,000 or fewer persons. We have determined that no number of small entities will experience an impact.Start Printed Page 38854
Today's rule contains no Federal mandates (under the regulatory provisions of Title II of the UMRA) for State, local, or tribal governments or the private sector. This final rule imposes no enforceable duty on any State, local or tribal governments or the private sector. This action corrects and clarifies existing regulations. The optional monitoring for disinfection profiling provides flexibility for PWSs to comply with LT1ESWTR. The earlier compliance date will not increase the cost of complying with LT1ESWTR since the monitoring and reporting requirements are unchanged. By specifying the detection limit for uranium, EPA provides States with the flexibility to waive some monitoring for PWSs with samples below the detection limit. Thus, today's final rule is not subject to the requirements of sections 202 and 205 of the UMRA.
EPA has determined that this rule contains no regulatory requirements that might significantly or uniquely affect small governments. This action corrects and clarifies existing regulations. Thus, today's proposed rule is not subject to the requirements of section 203 of the UMRA.
This final rule does not have Federalism implications. It will not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132. There is no cost to State and local governments, and the final rule does not preempt State law. This action corrects and clarifies existing regulations. The optional monitoring for disinfection profiling provides flexibility for PWSs to comply with LT1ESWTR. The earlier compliance date will not increase the cost of complying with LT1ESWTR since the monitoring and reporting requirements are unchanged. By specifying the detection limit for uranium, States have the flexibility to waive some monitoring for PWSs with samples below the detection limit. Thus, Executive Order 13132 does not apply to this final rule. In the spirit of Executive Order 13132, and consistent with EPA policy to promote communications between EPA and State and local governments, EPA specifically solicited comment on the proposed rule from State and local officials.
This final rule does not have tribal implications. It will not have substantial direct effects on tribal governments, on the relationship between the Federal government and Indian tribes, or on the distribution of power and responsibilities between the Federal government and Indian tribes, as specified in Executive Order 13175. There is no cost to tribal governments, and the rule does not preempt tribal law. This action corrects and clarifies existing regulations. Thus, Executive Order 13175 does not apply to this rule. Moreover, in the spirit of Executive Order 13175, and consistent with EPA policy to promote communications between EPA and tribal governments, EPA specifically solicited comment on the proposed rule from tribal officials.
This final rule is not subject to the Executive Order because it is not economically significant as defined in Executive Order 12866, and because the Agency does not have reason to believe the environmental health or safety risks addressed by this action present a disproportionate risk to children.Start Printed Page 38855
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2). This rule will be effective July 29, 2004, except for the amendment to § 141.85(c)(2)(iii) which is effective June 29, 2004.

Monitoring frequency and compliance requirements for radionuclides in community water systems.
(iv) If the gross beta particle activity minus the naturally occurring potassium-40 beta particle activity at a sampling point has a running annual average (computed quarterly) less than or equal to 15 pCi/L (screening level), the State may reduce the frequency of monitoring at that sampling point to every 3 years. Systems must collect the same type of samples required in paragraph (b)(2) of this section during the reduced monitoring period.
(5) If the gross beta particle activity minus the naturally occurring potassium-40 beta particle activity exceeds the appropriate screening level, an analysis of the sample must be performed to identify the major radioactive constituents present in the sample and the appropriate doses must be calculated and summed to determine compliance with § 141.66(d)(1), using the formula in § 141.66(d)(2). Doses must also be calculated and combined for measured levels of tritium and strontium to determine compliance.
