The US Environmental Protection Agency (EPA) stands as a formidable force in safeguarding our planet. EPA has been at the forefront of shaping environmental policies and regulations since its establishment in 1970. With a statutory focus on preserving air, water, and land resources, the agency administers key environmental laws including the Clean Air Act, Clean Water Act, and TSCA.

What is the EPA?

The Environmental Protection Agency, commonly known as the EPA, is a federal agency established by the U.S. government. It serves as a key regulatory body responsible for overseeing and enforcing environmental policies and regulations. With a primary focus on safeguarding human health and the environment, the EPA plays a vital role in shaping and implementing initiatives to address pressing environmental challenges.

EPA's Purpose and Creation

The EPA was created with the primary purpose of consolidating and streamlining federal efforts to protect the environment. It was established in 1970 during the administration of President Richard Nixon in response to increasing concerns about pollution and its impact on public health. The formation of the EPA aimed to centralize environmental responsibilities under one agency, ensuring efficient and effective management of environmental protection efforts.

EPA's Responsibilities and Functions

The EPA's responsibilities encompass a wide range of environmental concerns, and its functions are diverse and multi-faceted. Some of the key responsibilities of the EPA include:

  • Regulatory Oversight: The EPA is tasked with developing and enforcing regulations to mitigate environmental pollution and protect natural resources. By setting standards and guidelines, the agency ensures that industries, businesses, and individuals comply with environmental regulations and promote responsible practices.
  • Pollution Control: A significant function of the EPA is to regulate and control various types of pollution. This includes monitoring and reducing air pollution from industrial facilities, vehicles, and power plants, as well as addressing water pollution and hazardous waste management.
  • Environmental Research and Analysis: The EPA conducts extensive research and analysis to gather data, assess environmental risks, and identify potential threats. Through scientific studies and technological advancements, the agency strives to enhance its understanding of environmental challenges and develop effective strategies for their mitigation.

  • Collaboration and Partnerships: The EPA collaborates with various stakeholders, including other government agencies, industry representatives, environmental organizations, and the public. By fostering partnerships, the agency aims to promote shared responsibility and develop comprehensive approaches to environmental protection.

EPA's Regulatory Authority

The EPA possesses significant regulatory authority, granting it the power to enforce environmental regulations and oversee compliance. The agency regulates a wide range of environmental aspects, including air quality, water resources, hazardous substances, waste management, and more. Its authority is derived from various laws and acts, such as the Clean Air Act, Clean Water Act, Toxic Substances Control Act (TSCA), and others.

EPA's Impact and Achievements

Since its establishment, the EPA has made substantial contributions to environmental protection and sustainability. Some noteworthy achievements of the EPA include:

  • Improved Air Quality,
  • Enhanced Water Resource Management
  • Hazardous Waste Remediation
  • Promotion of Environmental Sustainability
  • Environmental Education and Awareness

The Environmental Protection Agency (EPA) is a vital federal agency dedicated to the protection of human health and the environment. With its regulatory authority, enforcement capabilities, and collaborative approach, the EPA plays a pivotal role in addressing environmental challenges, regulating pollution, and promoting sustainable practices. Through its efforts, the EPA has made significant achievements in improving air and water quality, managing hazardous waste, and fostering environmental stewardship. As the custodian of our environment, the EPA continues to work diligently to ensure a cleaner, healthier, and more sustainable future for all.

EPA Enforcement Priorities in 2025 and 2026

The EPA's enforcement focus has sharpened considerably since 2025. Two areas dominate the agency's current regulatory agenda: PFAS contamination and TSCA chemical reporting compliance.

EPA PFAS Enforcement: What Manufacturers Need to Know Now

On February 6, 2026, the EPA issued a formal statement confirming PFAS as a top enforcement priority across all agency programs. Several actions are now either in force or approaching final rulemaking:

PFOA and PFOS as Hazardous Substances: The EPA retained the rule designating PFOA and PFOS as hazardous substances under CERCLA, which directly affects Phase I environmental site assessments, Potentially Responsible Party determinations, and site cleanup liability.

Drinking Water MCLs Under Revision: On May 18, 2026, the EPA proposed two rules related to PFAS in drinking water. The first would rescind Biden-era regulations for PFHxS, PFNA, HFPO-DA, and hazard index mixtures. The second would extend the compliance deadlines for PFOA and PFOS Maximum Contaminant Levels to 2031. Comment periods close July 20, 2026.

TRI Reporting Expansion: 206 PFAS substances are now included in the Toxic Release Inventory program, with businesses responsible for submitting required reports by July 1, 2026.

TSCA PFAS Reporting Rule: The final TSCA PFAS Reporting Rule, which requires manufacturers and importers of PFAS chemicals to submit data covering an eleven-year period from 2011 to 2022, is expected to be published in June 2026.

RCRA Hazardous Constituents: The EPA plans to finalize a rule designating nine PFAS compounds, their salts and structural isomers, to the list of hazardous constituents under RCRA.

EPA TSCA Enforcement: Chemical Reporting Is the Current Pressure Point

TSCA enforcement has accelerated even as broader federal civil enforcement has slowed. In the third quarter of 2025, the EPA resolved 198 administrative enforcement actions across the statutes it administers, up from 179 in the prior quarter, and assessed over $9 million in penalties.

The EPA's TSCA enforcement program focuses on four key areas: new and existing chemicals, polychlorinated biphenyls (PCBs), asbestos, and lead-based paint. Chemical Data Reporting (CDR) noncompliance is a particular pressure point, with both the EPA and environmental NGOs filing actions against companies over reporting gaps.

In December 2025, the EPA announced it is dramatically expanding its imports investigative capacity and enforcement scope, launching broader investigations targeting illegal pesticide and chemical smuggling operations across multiple sectors.

For manufacturers managing supply chains with chemical inputs, the practical implication is straightforward: voluntary TSCA reporting gaps that went unaddressed in prior years are now enforcement targets. Companies should audit their Chemical Data Reporting obligations and PFAS inventory before the June 2026 TSCA PFAS Reporting Rule takes effect.

EPA compliance increasingly depends on knowing what substances are in your products and supply chain.

For manufacturers navigating US EPA-regulated frameworks including TSCA chemical reporting, PFAS restrictions under CERCLA, and Superfund compliance Regilient's agentic compliance platform maps your obligations across federal and state environmental requirements and keeps your documentation audit-ready as enforcement priorities shift.

Frequently Asked Questions

What is the EPA and what does it do?
The US Environmental Protection Agency (EPA) is a federal agency responsible for developing and enforcing environmental regulations that protect human health and the environment. It oversees air quality, water resources, hazardous substances, and waste management across the United States. Its core functions are regulatory oversight, pollution control, environmental research, enforcement and compliance, and collaboration with government, industry, and public stakeholders.
When and why was the EPA created?
The EPA was established in 1970 under President Richard Nixon, in response to rising public concern about pollution and its effect on public health. Its purpose was to consolidate federal environmental responsibilities, which had previously been scattered across multiple agencies, into a single body responsible for efficient and coordinated environmental protection.
What laws give the EPA its regulatory authority?
The EPA's authority is derived from a series of federal environmental statutes, including: The Clean Air Act, governing air quality and emissions standards The Clean Water Act, governing discharge into and protection of water resources The Toxic Substances Control Act (TSCA), governing the manufacture, import, and use of industrial chemicals Additional laws covering hazardous waste, pesticides, and safe drinking water Each statute grants the EPA specific powers to set standards, require reporting, and enforce compliance within its scope.
How does the EPA affect manufacturers and their supply chains?
The EPA directly affects manufacturers through chemical and substance regulation, most significantly under TSCA. TSCA gives the EPA authority to require reporting on chemical use, restrict or ban hazardous substances, and mandate risk management measures. For manufacturers, this means obligations such as TSCA Section 8(a)(7) PFAS reporting, PBT chemical restrictions under Section 6(h), and import certification requirements. Products containing regulated substances can face import refusal or enforcement action if EPA requirements are not met, making EPA compliance a supply chain data and documentation issue, not just a facility-level concern.
How does the EPA enforce environmental compliance?
The EPA holds authority to monitor, investigate, and penalise violations of environmental regulations. It conducts inspections, reviews mandatory reporting submissions, and can impose fines, penalties, and corrective action requirements where it identifies non-compliance. Enforcement can extend to imported products, meaning goods that fail to meet EPA chemical or substance requirements can be refused entry or subject to penalties after entry.
How does Regilient help manufacturers meet EPA regulatory requirements?
Regilient's agentic sustainability platform helps manufacturers meet EPA obligations that depend on supply chain data: TSCA compliance tracking, including Section 8(a)(7) PFAS reporting and Section 6(h) PBT restrictions Automated supplier engagement to collect the substance-level data EPA reporting requires BOM screening against EPA-regulated substance lists with alerts on new rulemaking Import certification documentation support and audit-ready record keeping For manufacturers managing EPA requirements alongside EU obligations such as REACH and RoHS, Regilient consolidates the overlapping supplier data into a single compliance programme.
