Environmental and occupational safety enforcement in the United States has never been purely a federal function. States have always played a significant role. What has changed in the current regulatory environment is the degree of divergence between what federal agencies are prioritizing and what state agencies are actively enforcing. For companies operating across multiple jurisdictions, the gap between those two tracks is where enforcement exposure is quietly accumulating.
At the federal level, EPA's stated Compliance First orientation and its preference for voluntary disclosure over adversarial enforcement have shifted the tone of federal environmental enforcement in ways that some regulated entities are reading as reduced overall pressure. OSHA's overall inspection numbers remain substantial, but enforcement emphasis has shifted in ways that some industries are reading, accurately in some respects, as a more permissive environment. What that reading misses is that state agencies have their own mandates, their own budgets, and their own political pressures. Several have responded to the current federal posture by doing exactly the opposite of what industry assumed they would.
California Is Still Running the Most Aggressive Environmental Enforcement Program in the Country
California operates its own environmental and occupational safety enforcement programs largely independent of federal direction. The California Air Resources Board (CARB), the State Water Resources Control Board, and the Department of Toxic Substances Control (DTSC) are all active enforcement agencies with independent statutory authority and budgets that do not depend on federal priorities.
For occupational safety, Cal/OSHA has maintained its inspection rates while the federal OSHA picture has shifted. California's Senate Bill (SB) 606, which created enterprise-wide citation authority for certain patterns of violations, remains in full effect. A company with 12 facilities in California that has a systemic safety violation pattern can receive citations covering all 12 facilities from a single enforcement action. The penalty structure follows per-violation math. The exposure for a large multi-site employer with a documented pattern of the same violation type across locations is not simply the cost of fixing the individual site where the inspector found it.
California also enforces its own heat illness standards independently of the federal heat rule rulemaking process. California's Heat Illness Prevention Standard requires specific protections at 80 degrees Fahrenheit, with additional high-heat provisions at 95 degrees. California's indoor heat standard, which took effect in July 2024, applies to workplaces where indoor temperatures reach 82 degrees. Neither of those thresholds or triggers appeared in the federal proposed rule. A company whose heat illness program is built around the federal proposal's framework is running a program that does not satisfy California requirements.
Oregon, Washington, Minnesota, Maryland, and Nevada Are Each Doing Something Different
California gets most of the attention in multi-state compliance conversations, partly because its economy and regulatory apparatus are so large. But the state plan landscape is more varied than a California-focused analysis captures.
Oregon and Washington have active state-level heat illness rules, and ergonomics remains an area of state-level policy attention in several jurisdictions. Minnesota maintains ergonomics requirements for certain high-risk sectors. Maryland implemented a new heat illness standard that took effect September 30, 2024, applying at an 80-degree Fahrenheit heat index. Nevada began enforcing new heat illness requirements in April 2025. These are not California-scale regulatory programs, but they cover real operating footprints, and they impose requirements that a federal OSHA compliance framework does not address.
On the environmental side, several state attorneys general have been explicit about their intention to use state environmental authority in areas where federal enforcement has become less active. New York, New Jersey, Illinois, and Massachusetts have all maintained active environmental enforcement programs. Washington state has expanded its use of state environmental law to address conditions that federal agencies are not pursuing under the current administration. For companies that mapped their compliance strategy against federal enforcement trends at the start of 2026 and have not revisited it, the state picture deserves a fresh look.
The Compliance Framework Problem That Creates State-Level Gaps
Most multi-site companies build their compliance programs around a federal baseline and then add state-specific requirements on top when they are flagged. The problem with that model is that it depends on the state-specific requirements being known and tracked. In practice, state regulatory changes often move faster than internal compliance frameworks adjust to capture them. A new heat standard in Maryland, an ergonomics update in Oregon, an enterprise-citation enforcement action in California: any of those can be in effect for months before a company's compliance team has formally updated its audit protocol to reflect them.
The gap is not usually a failure of intent. It is a capacity and tracking problem. State regulatory changes generate less national press coverage than federal rulemakings, move through different publication channels, and take effect on timelines that do not align with annual compliance review cycles. Companies without dedicated state regulatory tracking functions are almost certainly running programs that are behind in at least some of the jurisdictions where they operate.
What a Multi-Jurisdiction Compliance Gap Assessment Should Cover Before Inspection Season
For C-suite and operations leadership heading into the summer inspection window, the relevant question is not whether the company is federally compliant. It is which states in the operating footprint have implemented standards or enforcement priorities that differ materially from federal baselines, and whether those differences are reflected in site-level compliance programs and audit protocols.
That assessment has a few specific components. Heat illness program requirements need to be compared against the applicable standard in each operating state, not against the federal proposal. Ergonomics requirements need to be mapped by state, particularly for manufacturing and warehousing operations in Minnesota, where mandatory standards apply to certain sectors. For California operations specifically, the enterprise-wide citation framework means that site-level compliance gaps can have company-level financial consequences, which changes the risk calculus for how those gaps are prioritized and resourced.
The summer inspection window is a real enforcement season in high-hazard industries. State inspectors operate on their own schedules, not on federal priorities. The facilities that find out their state compliance programs are behind during an inspection are in a worse position than those that find out during an internal audit. That distinction has a dollar value, and right now it is larger than most compliance budgets have priced in.
