# Establishment of numeric criteria for priority toxic pollutants for the State of California.
**AGENCY:**
Environmental Protection Agency (EPA).
**ACTION:**
Final rule.
**SUMMARY:**
The Environmental Protection Agency (EPA) is taking final action to amend the Federal regulations to withdraw certain freshwater acute and chronic aquatic life water quality criteria and certain human health (water and organisms) water quality criteria, applicable to certain waters of California because California adopted, and the Agency approved, criteria for these parameters that are protective of the uses for the waterbodies. In this action, the EPA is amending the Federal regulations to withdraw those certain criteria applicable to California as described in the December 11, 2017 proposed rule. The withdrawal will enable California to implement their EPA-approved water quality criteria.
**DATES:**
This final rule is effective on November 15, 2018.

**I. General Information**
**A. Does this action apply to me?**
No one is affected by the final action contained in this document. This final action would merely serve to withdraw certain Federal water quality criteria that have been applicable to California and are no longer needed in light of the EPA-approved state water quality criteria. If you have any questions regarding the applicability of this action to a particular entity, consult the person identified in the preceding section entitled *FOR FURTHER INFORMATION CONTACT* .
**II. Background**
**A. What are the applicable Federal statutory and regulatory requirements?**
On May 18, 2000, the EPA promulgated a final rule known as the “California Toxics Rule” (“CTR”) at 40 CFR 131.38. The CTR final rule established numeric water quality criteria for priority toxic pollutants for the State of California, because the State had not complied fully with Section 303(c)(2)(B) of the Clean Water Act (CWA) (65 FR 31682).
Consistent with the basic tenet of the CWA, the EPA developed its water quality standards program emphasizing State primacy. Although in the CTR the EPA promulgated toxic criteria for California, the Agency prefers that states maintain primacy, revise their own standards, and achieve full compliance (see 57 FR 60860, December 22, 1992). As described in the preamble to the final CTR (see 65 FR 31682 (May 18, 2000)), when California adopts, and the EPA approves, water quality criteria that meet the requirements of the CWA, the Agency will issue a rule amending the CTR to withdraw the Federal criteria applicable to California.
On December 11, 2017, the EPA proposed the withdrawal of certain freshwater aquatic life (acute and chronic) water quality criteria and certain federally promulgated human health (water and organisms) water quality criteria, applicable in California (see 82 FR 58156, December 11, 2017). The EPA received comments on the proposed rule and a listing of the comments, and the Agency's responses, are contained in the document “Response to Comments for Water Quality Standards; Withdrawal of Certain Federal Water Quality Criteria Applicable to California: Lead, Chlorodibromomethane and Dichlorobromomethane,” which can be accessed at OW docket number EPA-HQ-OW-2017-0303. Today, the EPA is taking final action on its proposal. The withdrawal of the federally promulgated criteria will enable California to implement its EPA-approved water quality criteria for these parameters.
**B. What are the applicable Federal water quality criteria that the EPA is withdrawing?**
As discussed in the proposal (see 82 FR 58156, December 11, 2017), this final rule amends the Federal regulations in the CTR to withdraw the following criteria: freshwater acute and chronic aquatic life criteria for lead for the Los Angeles River and its tributaries; and human health (water & organisms) criteria for chlorodibromomethane and dichlorobromomethane for a segment of New Alamo Creek and a segment of Ulatis Creek. The EPA approved the State's criteria for lead and for chlorodibromomethane and dichlorobromomethane for these waters because the Agency determined that the State's criteria were scientifically sound and protective of the designated uses for these certain waters and met the requirements of the CWA and the Agency's implementing regulations at 40 CFR part 131. The State calls these criteria site-specific water quality objectives or site-specific objectives. More information on the EPA's actions which approved the California's site-specific objectives can be accessed at OW docket number EPA-HQ-OW-2017-0303.
This final rule will result in the withdrawal of the federally promulgated criteria for these certain waters under the CTR. However, the criteria for lead, chlorodibromomethane, and dichlorobromomethane for other waters in California that are currently part of the CTR remain in the Federal promulgation.
No changes to this final rule were made in response to the comments received on the proposed rule. The EPA received nine comments on the proposed rule through the public docket which are described in more detail in this section. Two anonymous comments and one environmental group opposed the proposed rule to withdraw certain Federal criteria because California's criteria are higher numerically than the Federal criteria. Regarding the State's aquatic life criteria for lead, the EPA indicated that the State has provided analyses that show the criteria are protective of aquatic life, and that the U.S. Fish and Wildlife Service agreed that the criteria would not likely adversely affect any listed threatened or endangered species or their critical habitat. Regarding the State's human health criteria for chlorodibromomethane and dichlorobromomethane, the EPA indicated in its response that, as described in Agency's Record of Decision supporting the approval of the state's criteria, states and authorized tribes have the flexibility to adopt water quality criteria that result in a risk level higher than 10 <sub>−6</sub> , up to the 10 <sub>−5</sub> level. That flexibility is constrained, however, by the need for careful consideration of the associated exposure parameter assumptions, and whether the resulting criteria would expose sensitive subpopulations consuming fish at higher rates to no more than a 10 <sub>−4</sub> cancer risk. The EPA determined that these certain state criteria assure that cancer risk to the most highly exposed population would not exceed a 10 <sub>−4</sub> cancer risk level. In addition, the consumption of the water and fish/shellfish from the affected waterbody segments does not currently occur, nor is it expected to occur in the future. The Sanitation Districts of Los Angeles County supported the proposed rule. Four comments were outside the scope of the proposed rule; and, one comment's position was not clear. Two emails were sent directly to the EPA after the comment period closed for the proposed rule, inquiring about how water quality criteria under the CWA are determined compared to the Maximum Contaminant Levels (MCLs) under the Safe Drinking Water Act (SDWA); the Agency's response, also included in the docket, stated that the CWA does not allow for consideration of costs and technological feasibility in the calculation of CWA water quality criteria, unlike SDWA MCLs. The EPA's “Response to Comments for Water Quality Standards; Withdrawal of Certain Federal Water Quality Criteria Applicable to California: Lead, Chlorodibromomethane and Dichlorobromomethane” can be accessed at OW docket number EPA-HQ-OW-2017-0303.
**III. Statutory and Executive Order Reviews**
**A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563:
Improving Regulation and Regulatory Review**
This action is not a significant regulatory action and was therefore not submitted to the Office of Management and Budget (OMB) for review.
**B. Executive Order 13771: Reducing Regulations and Controlling Regulatory Costs**
This action is a deregulatory action under Executive Order 13771. This rule is expected to provide meaningful burden reduction by withdrawal of certain federally promulgated criteria in certain waters of California.
**C. Paperwork Reduction Act (PRA)**
This action does not impose any new information collection burden under the PRA because it is administratively withdrawing Federal requirements that are no longer needed in California. It does not include any information collection, reporting, or recordkeeping requirements. The OMB has previously approved the information collection requirements contained in the existing regulations at 40 CFR part 131 and has assigned OMB control number 2040-0286.
**D. Regulatory Flexibility Act (RFA)**
The Regulatory Flexibility Act (RFA) generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute unless the agency certifies that the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental jurisdictions.
For purposes of assessing the impacts of this rule on small entities, small entity is 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.
I certify that this action will not have a significant economic impact on a substantial number of small entities under the RFA. This action will not impose any requirements on small entities.
**E. Unfunded Mandates Reform Act (UMRA)**
This action does not contain any unfunded mandate as described in UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect small governments. As this action withdraws certain federally promulgated criteria, the action imposes no enforceable duty on any state, local, or tribal governments, or the private sector.
**F. Executive Order 13132: Federalism**
This action 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. This rule imposes no regulatory requirements or costs on any state or local governments. Thus, Executive Order 13132 does not apply to this action.
In the spirit of Executive Order 13132, and consistent with the EPA policy to promote communications between the Agency and state and local governments, the Agency specifically solicited comment on this action from state and local officials.
**G. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments**
This action does not have tribal implications, as specified in Executive Order 13175. This rule imposes no regulatory requirements or costs on any tribal government. It does not have substantial direct effects on tribal governments, the relationship between the Federal Government and tribes, or on the distribution of power and responsibilities between the Federal Government and tribes. Thus, Executive Order 13175 does not apply to this action.
**H. Executive Order 13045: Protection of Children From Environmental Health and Safety Risks**
This action is not subject to Executive Order 13045 (62 FR 19885, April 23, 1997) because it is not economically significant as defined in Executive Order 12866, and because the Agency does not believe the environmental health or safety risks addressed by this action present a disproportionate risk to children.
**I. Executive Order 13211: Actions That Significantly Affect Energy Supply, Distribution, or Use**
This rule is not subject to Executive Order 13211, because it is not a significant regulatory action under Executive Order 12866.
**J. National Technology Transfer Advancement Act**
This rulemaking does not involve technical standards.
**K. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations**
Executive Order 12898 (59 FR 7629, February 16, 1994) establishes Federal executive policy on environmental justice. Its main provision directs Federal agencies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, as appropriate, disproportionately high and adverse human health or environmental effects of their programs, policies, and activities on minority populations and low-income populations in the United States.
The EPA believes that this action does not have disproportionately high and adverse human health or environmental effects on minority populations, low-income populations and/or indigenous peoples, as specified in Executive Order 12898 (59 FR 7629, February 16, 1994). The EPA has previously determined, based on the most current science and the Agency's CWA Section 304(a) recommended criteria, that California's adopted and the Agency-approved criteria are protective of human health.
**L. Congressional Review Act**
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. The 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 November 15, 2018.
