    (a) Definitions.--In this section, the following definitions apply:
            (1) Administrator.--The term ``Administrator'' means the 
        Administrator of the Environmental Protection Agency.
            (2) Affordability.--The term ``affordability'' means, with 
        respect to payment of a utility bill, a measure of whether an 
        individual customer or household can pay the bill without undue 
        hardship or unreasonable sacrifice in the essential lifestyle 
        or spending patterns of the individual or household, as 
        determined by the Administrator.
            (3) Financial capability.--The term ``financial 
        capability'' means the financial capability of a community to 
        make investments necessary to make water quality-related 
        improvements, taking into consideration the criteria described 
        in subsection (b)(2)(A).
            (4) Guidance.--The term ``guidance'' means the guidance 
        published by the Administrator entitled ``Combined Sewer 
        Overflows--Guidance for Financial Capability Assessment and 
        Schedule Development'' and dated February 1997, as applicable 
        to combined sewer overflows and sanitary sewer overflows.
    (b) Updating.--
            (1) In general.--Not later than 1 year after the date of 
        enactment of this Act, the Administrator shall update the 
        guidance to ensure that the evaluations by the Administrator of 
        financial capability assessment and schedule development meet 
        the criteria described in paragraph (2).
            (2) Criteria.--The criteria described in this paragraph are 
        that, under the updated guidance--
                    (A) in assessing the financial capability of a 
                community--
                            (i) greater emphasis should be placed on 
                        local economic conditions;
                            (ii) for regional systems, consideration 
                        should be given to the economic conditions of 
                        political jurisdictions and significant 
                        demographic groups within each region;
                            (iii) prescriptive formulas for use in 
                        calculating financial capability and thresholds 
                        for expenditure should not be considered to be 
                        the only indicator of the financial capability 
                        of a community;
                            (iv) site-specific local conditions should 
                        be taken into consideration in analyzing 
                        financial capability;
                            (v) a single measure of financial 
                        capability or affordability (such as median 
                        household income) should be viewed in the 
                        context of other economic measures, rather than 
                        as a threshold to be achieved; and
                            (vi)(I) consideration should be given to 
                        the economic outlook of a community, including 
                        the potential impact of program requirements 
                        over time, in the development of implementation 
                        schedules; and
                            (II) the assessment should take into 
                        consideration other essential community 
                        investments relating to water quality 
                        improvements;
                    (B) with respect to the timing of implementation of 
                water quality-related improvements--
                            (i) environmental improvement 
                        implementation schedules should be structured 
                        to mitigate the potential adverse impact on 
                        distressed populations resulting from the costs 
                        of the improvements;
                            (ii) implementation schedules should 
                        reflect local community financial conditions 
                        and economic impacts;
                            (iii) implementation schedules should allow 
                        permittees up to 30 years to implement water 
                        quality-related improvements in appropriate 
                        cases in which the cost of implementing the 
                        improvements places a high financial burden on 
                        the permittee; and
                            (iv) existing implementation schedules 
                        should be modified in appropriate cases taking 
                        into consideration the criteria set forth in 
                        this subparagraph;
                    (C) with respect to implementation--
                            (i) a determination of local financial 
                        capability may be achieved through an 
                        evaluation of an array of factors the relative 
                        importance of which may vary across regions and 
                        localities; and
                            (ii) an appropriate methodology should give 
                        consideration to such various factors as are 
                        appropriate to recognize the prevailing and 
                        projected economic concerns in a community; and
                    (D) the residential indicator should be revised to 
                include--
                            (i) a consideration of costs imposed upon 
                        ratepayers for essential utilities;
                            (ii) increased consideration and 
                        quantification of local community-imposed costs 
                        in regional systems;
                            (iii) a mechanism to assess impacts on 
                        communities with disparate economic conditions 
                        throughout the entire service area of a 
                        utility;
                            (iv) a consideration of the industrial and 
                        population trends of a community;
                            (v) recognition that--
                                    (I) the median household income of 
                                a service area reflects a numerical 
                                median rather than the distribution of 
                                incomes within the service area; and
                                    (II) more representative methods of 
                                determining affordability, such as 
                                shelter costs, essential utility 
                                payments, State affordability criteria, 
                                and State and local tax efforts, should 
                                be considered;
                            (vi) a consideration of low-income 
                        ratepayer percentages; and
                            (vii) impacts relating to program delivery, 
                        such as water quality infrastructure market 
                        saturation and program management.
            (3) Implementation.--The updated guidance should indicate 
        that, in a case in which a previously approved long-term 
        control plan or associated enforceable agreement does not 
        prohibit modification of the plan or terms of the agreement 
        (including financial capability considerations), and all 
        parties are in agreement that a change is needed or that the 
        plan or agreement does not prohibit reopening to address 
        changes in the economic or financial status of the community 
        since the effective date of the plan or agreement, 
        reconsideration and modification of financial capability 
        determinations and implementation schedules based on the 
        criteria described in paragraph (2) is appropriate.
            (4) Applicability.--The Administrator shall apply the 
        updated guidance, including the criteria described in paragraph 
        (2), to each determination and analysis of affordability, 
        financial capability, or widespread and substantial economic 
        impact related to implementation of a program under the Federal 
        Water Pollution Control Act (33 U.S.C. 1251 et seq.).
    (c) Publication and Submission.--Upon completion of the updating of 
guidance under subsection (b), the Administrator shall publish in the 
Federal Register and submit to the Committee on Environment and Public 
Works of the Senate and the Committee on Transportation and 
Infrastructure of the House of Representatives the updated guidance.

Clean Water Affordability Act of 2015  This bill amends the Federal Water Pollution Control Act (commonly known as the Clean Water Act) to require the Environmental Protection Agency (EPA) to establish a comprehensive and integrated planning approach to the permit obligations under the National Pollutant Discharge Elimination System (NPDES) program of a publicly owned treatment works (POTW) or a municipal separate storm sewer system.  A state may extend the term of a NPDES permit to up to 25 years under a state-administered NPDES program, if the permittee has an approved integrated plan. The EPA must update the guidance entitled &quot;Combined Sewer Overflows--Guidance for Financial Capability Assessment and Schedule Development,&quot; to ensure that the evaluations by the EPA of financial capability assessment and schedule development meet specified criteria. States must set aside 15% of the amount of each capitalization grant they receive for water pollution control revolving funds to provide assistance to municipalities of fewer than 10,000 individuals that meet specified affordability criteria for activities on the state's priority list of POTW construction projects. Effluent limitations must be applied at the final point of discharge from a POTW treatment facility and not to flows within the facility. The EPA may issue NPDES permits with modified effluent limits for discharges of pollutants from a collection system servicing a POTW during periods of peak wet weather if a state concurs and the permit applicant has an approved peak wet weather management plan. States may adopt peak wet weather-related water quality standards for receiving waters during periods of peak wet weather events. The EPA must develop and publish guidance with respect to peak wet weather-related water quality standards and waste water management practices.
