EPA Finalizes Analytical Methods Update Rule
This week EPA finalized and published the Clean Water Act Methods Update Rule for the Analysis of Effluent. One of EPA’s responsibilities is to approve analytical methods for measuring regulated pollutants in wastewater. The regulated community and laboratories use these approved methods for determining compliance with NPDES permits or other monitoring requirements. In this final rule EPA is promulgating changes to analytical methods and test procedures used by municipalities and industries to analyze the chemical, physical, and biological components of wastewater required by regulations under the Clean Water Act. Changes include revised EPA methods, revised methods published by voluntary consensus standard bodies (e.g. ASTM), new methods reviewed under the Alternate Test Procedures (ATP) program including clarifying procedures for EPA approval of nationwide and limited use ATPs, and procedure revisions for determining method detection limit. EPA believes “these changes will provide increased flexibility for the regulated community in meeting monitoring requirements while improving data quality. In addition, this update to the CWA methods is incorporating technological advances in analytical technology.” This final rule is effective July 19, 2021.
IG Report: Resource Constraints, Leadership Decisions, and Workforce Culture Led to a Decline in Federal Enforcement
On May 13, 2021 EPA’s Office of Inspector General (IG) issued a report which indicated that EPA’s compliance monitoring activities, enforcement actions, monetary enforcement results, and environmental benefits generally declined from FYs 2007 through 2018 nationwide. The IG noted this downward trend also occurred at the regional level and on a statute-by-statute basis. While annual enforcement measures, such as penalty dollars assessed or commitments to clean up pollution, declined, the results varied year-to-year based on the conclusion of large cases.
IG determined that the decline in enforcement resources was a primary driver behind the observed declining enforcement trends, resulting in fewer compliance monitoring activities and concluded enforcement actions. The IG believes EPA leadership also made strategic decisions that affected enforcement trends, such as focusing limited resources on the most serious cases and, in 2017, emphasizing deference to state enforcement programs and compliance assistance.
The IG concluded that EPA’s annual enforcement reports do not provide context for understanding the EPA’s enforcement accomplishments and the impact these enforcement activities have on human health and the environment. “For example, the EPA does not measure or report data for compliance-assistance activities, informal enforcement actions, and noncompliance rates.” The IG recommended that EPA also provide additional information such as the type of inspections conducted and the types and toxicity of pollutants removed from the environment.
The IG provided numerous recommendations to the Office of Enforcement and Compliance assurance, most of which remain unresolved. A copy of the report can be found here: Resource Constraints, Leadership Decisions, and Workforce Culture Led to a Decline in Federal Enforcement (epa.gov)
USGS Study: Potential toxicity of pesticides to aquatic life in US rivers is widespread
What is already known on this topic?
Pesticides are a threat to healthy freshwater ecosystems, but expense and logistics of large-scale studies have impeded an understanding of the impacts of pesticides on a national scale.
What is added by this study?
This study assessed concentrations of 221 pesticides measured during 2013–2017 in streams and rivers across the conterminous United States, compared the results to data on pesticide use, and evaluated the concentrations in terms of EPA aquatic- and human-health criteria.
What are the implications for water availability?
Exceedances of a human-health benchmark were rare, but numerous sites had one or more exceedances of a chronic or acute benchmark for aquatic life. Agricultural use of pesticides contributed to some of the highest concentrations of pesticides in streams and rivers.
A new USGS study of pesticides in U.S. rivers and streams reports that, on average, 17 pesticides were detected at least once at the 74 river and stream sites sampled 12 to 24 times per year during 2013–2017. Herbicides were detected much more frequently than insecticides and fungicides.
The number of pesticides detected at a site over the study mirrored the intensity of pesticide use in the region where the site was located. Pesticide use intensity was greatest in the Midwest (49 kg/km2), where 25 pesticides were detected, on average, at each site. Herbicides were heavily used in agricultural settings and were consistently detected in surface waters at concentrations > 100 ng/L. In contrast, insecticides had lower agricultural-use intensities and surface-water detection frequencies at concentrations > 100 ng/L were rare.
An EPA chronic aquatic-life benchmark—estimates of the concentrations below which pesticides are not expected to represent a risk to aquatic life—was exceeded at least once at more than half of the stream sites in every region—Midwest, South, Northeast, West, and Pacific. Such exceedances indicate the potential for harmful effects to aquatic life such as fish, algae, and invertebrates like aquatic insects. However, an EPA human-health benchmark was exceeded only four times (1.1% of samples).
Of the 221 pesticides measured, just 17 were responsible for the aquatic-life benchmark exceedances. Many of these 17 were herbicides, which frequently occurred at relatively high concentrations that exceeded benchmarks for fish, invertebrates, and plants. Others were insecticides, which occurred at lower concentrations, but are much more toxic to aquatic invertebrates than herbicides.

EPA Announces Environmental Justice Consultations on Risk Management Rulemakings for TSCA Chemicals
The U.S. Environmental Protection Agency (EPA) invites environmental justice communities and stakeholders to participate in environmental justice consultations regarding the development of risk management actions under section 6(a) of the Toxic Substances Control Act (TSCA). The first consultations will focus on Asbestos, Part 1: Chrysotile Asbestos, Pigment Violet 29, Trichloroethylene (TCE) and Perchloroethylene (PCE) in June 2021.
EPA is offering these sessions to increase opportunities for participation. Sessions will provide an overview of the TSCA risk management requirements, the findings from the final risk evaluations, the tools available to manage the unreasonable risks, and an opportunity for input on environmental justice concerns. These consultations are open to the public, and EPA is inviting national, local, and non-governmental organizations, communities, and other interested stakeholders to participate. In addition to these environmental justice consultations, EPA is implementing a robust outreach effort on risk management that includes consultations with small businesses, state and local governments, and tribes. There will also be an open public comment period on proposed risk management actions.
Find registration information for the environmental justice consultations and more information on EPA’s risk management outreach here.
While outreach and stakeholder engagement on risk management activities for these chemicals moves forward, EPA is also reviewing final risk evaluations for these chemicals to ensure that they reflect the best available science and protect human health and the environment, in accordance with the Executive Orders and other direction provided by the Biden-Harris Administration. The agency will keep stakeholders updated as decisions are made and next steps are determined.
This first sessions will take place in June 2021. EPA is planning additional Environmental Justice Consultations on proposed risk management actions under section 6(a) of the Toxic Substances Control Act. For mor information visit Risk Management for Existing Chemicals under TSCA or subscribe to the Office of Pollution Prevention and Toxics listserv here.
EPA Responds to Phosphoric Acid, Phosphogympsum Wastewater Petition Under TSCA
Today, EPA announced the availability of the Agency’s response to a portion of a petition it received February 8, 2021, from 18 organizations requesting EPA take several actions under section 7004(a) of RCRA; section 21 of TSCA; and section 553 of the APA related to phosphogypsum and process wastewater from phosphoric acid production (process wastewater). EPA has determined that only one of those actions is an appropriate request under TSCA Section 21: A request to issue a test rule under TSCA requiring testing of phosphogypsum and process wastewater from phosphoric acid production. EPA is treating the other portions of the petition involving TSCA as a petition under the Administrative Procedure Act (APA); those other portions request EPA to initiate the prioritization process for designating phosphogypsum and process wastewater as high-priority substances for risk evaluation, and to make a determination by rule under TSCA that the use of phosphogypsum in road construction is a significant new use.
After careful consideration, EPA has denied the request to initiate a proceeding to issue a test rule TSCA section 4 because the TSCA section 21 petition does not set forth the facts establishing that it is necessary for the Agency to issue such a rule. In particular, the petition does not demonstrate that existing information and experience on the effects of phosphogypsum and process wastewater are insufficient or that testing of phosphogypsum and process wastewater with respect to such effects is necessary to develop such information. Therefore, the petitioners have not demonstrated that the rule they requested is necessary.
Today’s announcement does not provide EPA’s response to two other TSCA-requested actions: that EPA is to initiate the prioritization process for designating phosphogypsum and process wastewater as high-priority substances for risk evaluation, and to make a determination by rule under TSCA that the use of phosphogypsum in road construction is a significant new use. EPA is treating these two portions of the petition involving TSCA as a petition under the Administrative Procedure Act (APA). Today’s announcement also does not address the petitioners’ requests under the Resource Conservation and Recovery Act (RCRA).

In Case You Missed It: NOAA Revises Climate Normals
Every 10 years, NOAA releases an analysis of U.S. weather of the past three decades that calculates average values for temperature, rainfall and other conditions. That time has come again. Known as the U.S. Climate Normals, these 30-year averages — now spanning 1991-2020 — represent the new “normals” of our changing climate. They are calculated using climate observations collected at local weather stations across the country and are corrected for bad or missing values and any changes to the weather station over time before becoming part of the climate record.
Simply stated: The Normals are the basis for judging how daily, monthly and annual climate conditions compare to what’s normal for a specific location in today’s climate.
The U.S. Climate Normals are a large suite of data products that provide information about typical climate conditions for thousands of locations across the United States. Normals act both as a ruler to compare today’s weather and tomorrow’s forecast, and as a predictor of conditions in the near future. The official normals are calculated for a uniform 30 year period, and consist of annual/seasonal, monthly, daily, and hourly averages and statistics of temperature, precipitation, and other climatological variables from almost 15,000 U.S. weather stations.
NCEI generates the official U.S. normals every 10 years in keeping with the needs of our user community and the requirements of the World Meteorological Organization (WMO) and National Weather Service (NWS). The 1991–2020 U.S. Climate Normals are the latest in a series of decadal normals first produced in the 1950s. These data allow travelers to pack the right clothes, farmers to plant the best crop varieties, and utilities to plan for seasonal energy usage. Many other important economic decisions that are made beyond the predictive range of standard weather forecasts are either based on or influenced by climate normals.
For the past decade, the Normals have been based on weather observations from 1981 to 2010. In early May, climate experts at NOAA’s National Centers for Environmental Information (NCEI) issued an updated collection based on the weather occurring from 1991 to 2020. The data set reflects a “new normal” that takes the most recent 30 years of climate change-influenced weather and climate conditions into account. (More: See our Climate Normals Explainer.)

EPA Tools & Resources Training Webinar: Virtual Beach (VB)
June 3, 2021
3:00-4:00 pm EDT
To protect public health, beach managers need to continually assess the level of potentially harmful microbes in the water. However, traditional culture-based testing methods take a full 24 hours to get results – preventing same-day, proactive beach closures and leaving many recreational swimmers open to sickness or infection, or potentially close a beach needlessly and incur economic losses. EPA’s Virtual Beach (VB) software offers a solution. VB is a decision support tool that facilitates the development of statistical models of water quality at site-specific locations. It allows users to estimate any general response variable using commonly measured environmental data. These estimates can then be used to inform site-based management decisions, such as issuing swimming or shellfish harvesting advisories. This webinar will feature a live demonstration of VB3 – a desktop PC application. We will discuss how VB is used to assist in advisory issuances in the Great Lakes states and to forecast water conditions in states and other recent case study examples. For more information, visit the Virtual Beach webpage.

Harmful Algal Blooms and Algal Toxins
May 25th | 2:00-3:30 PM ET
Presentation 1: How Cyanobacteria Work: Converting Sunlight Into Usable Energy. Cyanobacteria are widely known for their toxin producing and bloom-forming capabilities. Although cyanobacterial blooms can be a threat to public and ecosystem health, they are also globally important producers of oxygen. This presentation will give a detailed introduction of photosynthesis in cyanobacteria. It will also explore how the photosynthetic processes differ between cyanobacteria and plants and will provide some explanation as to why cyanobacteria seem to thrive in conditions that would hinder the growth of green algae. (Presentation Anna Boegehold, EPA’s Office of Research and Development)
Presentation 2: Cyanotoxins in Oregon: Transitioning to Mandatory Monitoring for Susceptible Sources. In 2018, when a large system detected cyanotoxins above the EPA health advisory level in treated water, Oregon moved from a voluntary cyanotoxin sampling program to mandatory monitoring. This presentation will cover how Oregon transitioned from the voluntary program to mandatory monitoring for cyanotoxins at susceptible sources and will discuss what the regulations require and statewide results, issues encountered, and what resources have been created to assist public water systems. Attendees will learn about the risk of cyanotoxins and what system operators can do to minimize this risk. (Presentation by Kari Salis, Oregon Health Authority)
