The EPA wants to make sure the water we use is super clean by checking for some bad stuff like PFAS and PCB, and they want to update how they test for these. They also want to make some parts of this process easier and fix some small mistakes.
Summary AI
The Environmental Protection Agency (EPA) has proposed updates to the Clean Water Act methods for analyzing pollutants in effluent. This rule aims to improve data quality and consistency by introducing new methods for detecting specific substances like PFAS and PCB congeners, while withdrawing outdated testing parameters and methods. Additionally, the proposal includes simplifying certain sampling requirements and making minor corrections to existing tables of approved methods. Public comments on this proposal are invited until February 20, 2025.
Abstract
The U.S. Environmental Protection Agency (EPA) is proposing to promulgate new methods and update the tables of approved methods for the Clean Water Act. The Clean Water Act requires the EPA to promulgate test procedures for the analysis of pollutants. Promulgating new methods and updating the tables of approved methods increases the quality and consistency of data collected for the purposes of the Clean Water Act. In this rule, the EPA proposes to add new EPA methods for per- and polyfluoroalkyl substances (PFAS) and polychlorinated biphenyl (PCB) congeners, and add methods previously published by voluntary consensus bodies that industries and municipalities would use for reporting under the EPA's National Pollutant Discharge Elimination System permit program. The EPA also proposes to withdraw the seven Aroclor (PCB mixtures) parameters. In addition, the EPA is proposing to simplify the sampling requirements for two volatile organic compounds, and make a series of minor corrections to existing tables of approved methods. This proposed rule does not mandate when a parameter must be monitored or establish a discharge limit.

Overview
The document outlines a proposed rule by the U.S. Environmental Protection Agency (EPA) to update methods under the Clean Water Act for analyzing pollutants in effluent. The primary goal is to improve the quality and consistency of environmental data. This proposal introduces new testing methods for specific contaminants, such as per- and polyfluoroalkyl substances (PFAS) and polychlorinated biphenyl (PCB) congeners. Additionally, it suggests removing outdated testing parameters and methods, simplifying some sampling requirements, and amending approved methods tables. Public comments on the proposal are being accepted until February 20, 2025.
Significant Issues and Concerns
One concern is the incorporation of certain standards by reference, which may require stakeholders to purchase these standards. Described as not a significant financial burden, this could nonetheless be challenging for smaller entities. The document's heavy use of technical terms and regulatory references may also pose comprehension challenges for individuals or organizations without specialized legal or technical expertise.
Furthermore, the rationale for some changes, particularly the withdrawal of outdated methods, is briefly mentioned. More detailed justifications would aid in understanding the necessity of these updates. The document lacks in-depth information on potential cost implications or impacts on small businesses and municipal entities, which may face increased difficulty adapting to new regulations.
Public Impact
The proposed rule is not set to have immediate effects on current National Pollutant Discharge Elimination System (NPDES) permits. However, the changes could eventually influence monitoring practices and regulatory compliance in the long term. By updating analytical procedures, the EPA aims to ensure that environmental data related to water pollution is accurate and reliable, ultimately fostering better water quality management.
Impact on Stakeholders
Positive Impacts:
- Regulators and Environmental Agencies: Enhanced methods may lead to more accurate pollutant tracking, aiding in environmental protection efforts.
- Public Health: Indirectly, improvements in water quality could benefit public health by ensuring safer water sources.
Negative Impacts:
- Small Businesses and Municipal Entities: These groups may experience challenges due to potential costs associated with new standard purchases and method implementation. The lack of detailed guidance on transitioning to new methods could also cause difficulties.
- General Public and Laypersons: The complexity of the document might make it challenging for the broader public to engage with the policy changes effectively.
Conclusion
The EPA's proposed updates to Clean Water Act testing methods aim to improve environmental data quality and consistency, but they come with potential costs and adaptation challenges for smaller entities. Greater clarity and transitional guidance are advised to fully understand and implement these changes effectively. Moreover, ensuring that the general public can comprehend these updates will require more straightforward communication of the benefits and practical aspects of this proposal.
Financial Assessment
In the proposed rule regarding updates to the Clean Water Act methods, there is a specific reference to the costs associated with obtaining certain technical standards that are incorporated by reference. These standards are available through websites such as standardmethods.org and astm.org, as developed by Voluntary Consensus Standards Bodies (VCSBs). The prices for accessing these standards are generally set between $60 and $80.
The document's financial reference highlights a potential concern for stakeholders, particularly smaller businesses or municipalities, which may find even these seemingly moderate costs to be a financial burden. The issue is that while the rule suggests that these expenses are not significant, they could add up for entities needing to access multiple standards to comply with new regulations. This cost consideration is especially relevant in the context of the issues identified, such as the need for smaller entities to quickly adapt to new regulatory requirements.
Moreover, assuming that stakeholders are required to purchase access to multiple standards, it might also raise questions about the cumulative financial impact on these entities. The proposed rule does not delve into whether assistance or cost mitigation strategies are available for such stakeholders, which ties into another identified issue: the lack of detailed information on the cost implications for smaller entities.
The availability of these standards at a cost points to a broader issue of accessibility. Stakeholders with fewer resources may be disproportionately affected, an issue that is understated in the proposal. The document does not provide a comprehensive strategy to accommodate smaller businesses or propose any financial support or exemptions for these entities, leaving a gap between regulatory intentions and practical implementation.
In summary, while the document assures that the cost for accessing necessary standards is not prohibitive, it underestimates the potential financial pressure on smaller stakeholders. An emphasis on additional support or a detailed financial impact analysis could better equip stakeholders to meet the proposed requirements without undue financial strain.
Issues
• The proposal involves incorporating certain standards by reference, which might require stakeholders to purchase access to these standards at a cost. This could pose a financial burden to smaller entities, even if described as 'not significant'.
• The extensive use of technical terminology and references to regulatory codes might be difficult for laypersons or smaller entities without legal or technical expertise to fully understand without further explanation.
• The rationale for some of the changes, such as the withdrawal of outdated methods, is provided briefly. Additional justification or detail might help in understanding the necessity and impact of these changes.
• There is a lack of detailed information regarding the potential impact or cost implications for small businesses or smaller municipal entities, which may not be as equipped to quickly adapt to new regulatory requirements.
• While the proposed rule assures no immediate impact on current NPDES permits, a more detailed transition plan or guidance for affected parties could be beneficial.
• The document references several studies and validation reports (e.g., 'EPA Method Study 18 Method 608'), but does not summarize the findings, which might help in clarifying the implications of the changes.
• Some sections are technical and lengthy, which could benefit from summaries or simplifications to aid comprehension by non-expert stakeholders.
• The process for incorporating methods by reference, and the availability of these methods, could be clarified further, specifically for stakeholders unfamiliar with the federal regulatory process.
