What environmental law actually covers

Environmental law in the US is built on a stack of federal statutes administered primarily by the EPA, with parallel state agency programs that often have authority delegated by EPA. The major federal statutes:

• Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA / Superfund) — strict, joint, and several liability for parties responsible for releases of hazardous substances. Cleanup costs can reach hundreds of millions of dollars per site. Section 107 cost recovery and Section 113 contribution actions among potentially responsible parties (PRPs) are routine.
• Resource Conservation and Recovery Act (RCRA) — cradle-to-grave regulation of hazardous waste. Permitting, manifesting, storage, treatment, and disposal requirements. Citizen suits available to neighbors and NGOs.
• Clean Water Act (CWA) — discharges to waters of the United States. NPDES permits, stormwater, wetlands and Section 404, oil spill liability under Section 311.
• Clean Air Act (CAA) — stationary and mobile source emissions. PSD/NSR permitting, Title V operating permits, NESHAPs, NSPS, hazardous air pollutants, and the criminal provisions that have produced corporate prosecutions.
• Toxic Substances Control Act (TSCA) — manufacturing and import of chemicals, including the recent reform that gave EPA broader authority. PFAS, asbestos, and lead are major active areas.
• Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) — pesticide registration, use, and labeling.
• Safe Drinking Water Act (SDWA) — public water systems and underground injection control.
• Emergency Planning and Community Right-to-Know Act (EPCRA) — toxics release inventory reporting and emergency planning.
• Endangered Species Act (ESA) — protected species and habitat. Section 7 consultation and Section 10 incidental take permits.
• National Environmental Policy Act (NEPA) — environmental review for federal actions, including permits and approvals.
• State environmental laws — including state superfund programs, state-level hazardous waste regulation, brownfields incentives, and increasingly, state PFAS regulation, environmental justice statutes, and climate disclosure laws.

EPA enforcement — what to expect when an inspector shows up

EPA inspections begin at the gate with a presentation of credentials and a notice of inspection. The inspector's authority varies by program but is generally broad. Best practices:

1. Cooperate, but read the consent or warrant carefully. Do not consent to scope you are not required to consent to.
2. Notify counsel immediately. The inspector's questions and your answers can be used in subsequent civil and criminal cases.
3. Take parallel samples when EPA samples your facility. Ensure chain-of-custody documentation.
4. Keep detailed contemporaneous notes. What was inspected, what was photographed, what was discussed, what was sampled.
5. Conduct a closing conference. Ask what areas of concern the inspector identified. Address obvious issues immediately.
6. After the inspection, debrief with counsel. Plan voluntary corrections, internal investigation if needed, and response to any inspection findings.

Inspections often lead to a Notice of Violation, Section 308 Information Request, or Administrative Order. Each carries its own response deadlines, often very short. Counsel involvement before responding is essential.

CERCLA / Superfund liability — strict, joint, and several

CERCLA imposes liability on five categories of "potentially responsible parties" — current owners and operators of contaminated sites, owners and operators at the time of disposal, generators who arranged for disposal, transporters who selected the disposal site, and certain other parties. Liability is:

• Strict — no need for the government to prove negligence or fault
• Joint and several — any one PRP can be held liable for the entire cleanup cost
• Retroactive — applies to disposals that were entirely legal at the time

This combination produces extraordinary exposure. A single tenant who used a contaminated site for one year decades ago can be held responsible for tens of millions in cleanup costs. The defenses are narrow — the bona fide prospective purchaser defense, the contiguous property owner defense, the third-party defense, and innocent landowner defense — and each requires specific factual elements, including environmental due diligence at the time of acquisition.

Cleanup itself proceeds through a structured process: Preliminary Assessment, Site Inspection, Remedial Investigation/Feasibility Study (RI/FS), Record of Decision (ROD), Remedial Design/Remedial Action (RD/RA), and Operation and Maintenance (O&M). At each stage, PRPs negotiate consent decrees, allocations among PRPs, and disputes with EPA over remedy selection.

Real estate transactions and environmental due diligence

Almost every commercial real estate transaction involves environmental due diligence. The All Appropriate Inquiries Standard under CERCLA (40 CFR Part 312) is the core requirement, satisfied through ASTM E1527-21 Phase I Environmental Site Assessments. Without proper Phase I performed before acquisition, the buyer cannot claim the bona fide prospective purchaser defense or innocent landowner defense.

Phase I assessments review historical land use, regulatory database records, site reconnaissance, and interviews. If recognized environmental conditions are identified, Phase II investigation (sampling) follows. Phase III is remediation.

Brownfields redevelopment programs in most states provide reduced liability for purchasers who meet program requirements, often combined with state and federal grants and tax credits. Counsel involvement at the negotiation stage often saves multiples of fee in transaction terms — environmental indemnities, escrows, environmental insurance, and post-closing access agreements.

PFAS — the legal field that is reshaping environmental law

Per- and polyfluoroalkyl substances (PFAS) — sometimes called "forever chemicals" — are a class of thousands of chemicals used in firefighting foam, non-stick coatings, water-resistant fabrics, food packaging, semiconductors, and many other products. They are persistent in the environment, bioaccumulate in humans, and are increasingly regulated.

Recent and ongoing developments:

• EPA designated PFOA and PFOS as CERCLA hazardous substances
• EPA Maximum Contaminant Levels under the Safe Drinking Water Act for several PFAS compounds
• State PFAS bans on consumer products in food packaging, textiles, cosmetics, and firefighting foam
• State drinking water standards stricter than federal in many states
• Class action and personal injury litigation in dozens of jurisdictions
• Multidistrict litigation against firefighting foam manufacturers and users
• Insurance coverage litigation over policies decades old

Companies with any PFAS exposure — manufacturers, users, water utilities, airports, military installations, and industrial sites — should have a PFAS strategy now, not in five years.

Environmental criminal exposure

Many environmental statutes carry criminal as well as civil penalties. Knowing violations of the Clean Water Act, Clean Air Act, RCRA, and TSCA can result in personal prosecution of officers and employees. The Department of Justice's Environmental Crimes Section pursues hundreds of defendants annually. Common charges:

• Knowing discharge of pollutants without a permit
• False statements in permit applications and reports
• Tampering with monitoring equipment
• Illegal disposal of hazardous waste
• Endangering employees or the public
• Conspiracy and obstruction

The "responsible corporate officer" doctrine creates strict liability for senior executives of companies that violate the Clean Water Act, even without proof that the executive personally directed the violation. Internal investigations and parallel proceedings (civil and criminal at the same time) are common. Joint defense agreements among potentially responsible individuals can be useful but introduce their own complexities.

Environmental justice and tribal consultation

Environmental justice — the recognition that pollution and environmental hazards disproportionately affect minority and low-income communities — has become a central organizing principle for federal and state environmental enforcement. EPA prioritizes enforcement in EJ communities, NEPA reviews must consider EJ impacts, and several states have adopted statutes specifically requiring EJ analysis for permit applications. Tribal consultation requirements under federal trust responsibilities apply to projects on or near tribal lands.

Permit applicants who do not address EJ and tribal consultation early in the process face delays, denials, and litigation challenges from environmental groups and affected communities.

Climate disclosure and ESG

The intersection of environmental law and corporate disclosure has expanded rapidly. The SEC's climate disclosure rule, California's SB 253 and SB 261 climate disclosure laws, the EU's Corporate Sustainability Reporting Directive applied to US companies with EU operations, and shareholder activist campaigns all require coordinated environmental and securities counsel. Greenwashing claims by regulators, plaintiffs, and the FTC are now a significant area of disputes.

Choosing the right environmental lawyer

Environmental practice is highly specialized within itself. Make sure your counsel matches the situation:

• Permitting and compliance counseling — for facility expansions, new permits, and regulatory navigation
• Enforcement defense — for active EPA or state enforcement actions
• Environmental criminal defense — for parallel proceedings or grand jury investigations
• Superfund / CERCLA — for cleanup negotiations and PRP allocations
• Real estate / transactional environmental — for diligence, indemnities, and brownfields work
• Toxic torts — for personal injury and property damage litigation
• Insurance coverage — for recovery against historical policies
• Climate / ESG / disclosure — for corporate reporting and securities exposure

What does a environmental attorney actually cost?

Environmental work is almost entirely hourly. The single biggest cost driver is consultants — environmental engineers, hydrogeologists, toxicologists, and risk assessors — whose fees often exceed legal fees on cleanup matters. The cost of doing diligence right before a transaction is reliably less than the cost of cleaning up problems discovered after closing. The same is true of compliance: routine compliance counseling is much less expensive than enforcement defense.
