Environmental Permits for Terramation Facilities (colloquially referred to as human composting)

Natural organic reduction (NOR) — terramation — produces no toxic emissions, no formaldehyde, and no mercury. But that doesn’t mean facilities operate without environmental oversight. Like any facility that processes biological material, NOR operations are subject to state environmental permitting requirements covering stormwater, air quality, solid waste handling, and zoning compliance. Understanding how environmental permits work for terramation is important both for facilities operating or planning to open, and for consumers who want to know that regulated facilities are doing things right.

What environmental permits does a terramation facility need?

NOR facilities must obtain environmental permits from their state environmental agency — there is no federal EPA permit program specific to NOR. Permit requirements typically cover air quality compliance (NOR produces CO₂ and water vapor, far less regulated than crematory mercury emissions), stormwater management, solid waste handling of non-biological materials, and local zoning compliance. Washington State's Department of Ecology has the most developed framework, in place since 2020, and serves as the model other states use.

Environmental permits for NOR facilities are issued at the state level — the EPA has no NOR-specific permitting program as of 2026.
NOR's air quality permitting burden is substantially lighter than cremation's because the process produces CO₂ and water vapor rather than particulate matter and mercury vapor.
Stormwater management, solid waste handling of recovered metals, and local zoning compliance are the primary environmental permit categories for NOR facilities.
Washington's Department of Ecology (WAC 173-350-240) developed the pioneering NOR environmental framework; Colorado's CDPHE and Oregon's DEQ are the lead agencies in their states.
Operators should engage their state environmental agency before facility construction begins — retroactive permitting is costly and can delay or force closure.
Consumers evaluating providers can ask whether the facility holds all required state environmental permits in good standing — legitimate providers will answer directly.

Why Do NOR Facilities Need Environmental Permits?

Environmental permitting exists to protect air, water, and soil quality — and to ensure that facilities processing organic material do so safely and consistently. Even though NOR’s environmental footprint is dramatically lower than cremation, the process still involves biological material, temperature-controlled vessels, and the production of outputs (soil, CO₂, and water vapor) that fall under state environmental agency jurisdiction.

Permits are not a sign that a process is dangerous. They are a sign that regulators have established standards, that facilities must demonstrate compliance, and that oversight is ongoing. For NOR, environmental permitting is part of a broader quality framework that also includes health department licensing, operator certification, and chain-of-custody documentation.

What Do Environmental Permits for NOR Typically Cover?

The specific requirements vary by state, but NOR facility environmental permits generally address these areas:

Air quality compliance. The NOR process generates carbon dioxide (CO₂) and water vapor — the natural byproducts of aerobic decomposition. These are not regulated pollutants at the levels NOR produces, but facilities may still need to register with their state environmental agency under general air quality compliance requirements. This is a significant contrast to cremation, where crematories must obtain specific air quality permits to control particulate matter and mercury emissions from dental fillings.

Stormwater management. Facilities must manage surface water runoff to prevent any potential contamination of waterways. This typically involves stormwater management plans and, in some cases, specific drainage infrastructure depending on the facility design and local watershed protections.

Solid waste handling. During the NOR process, non-biological materials (metals removed from remains, for example) must be handled and disposed of according to solid waste regulations. Some state frameworks also address the classification of the finished soil product — specifically whether it is classified as a soil amendment, compost, or a distinct new category.

Zoning and land use compliance. NOR facilities must comply with local zoning requirements. Some municipalities have required specific use permits or zoning variances to allow NOR operations, particularly in areas zoned primarily for retail funeral services.

How Has Washington State Developed Its NOR Permitting Framework?

Washington, which became the first state to legalize NOR in 2019 through SB 5001, has developed the most comprehensive environmental permitting framework for NOR operations. The Washington State Department of Ecology (WA DOE) has worked alongside the Washington Department of Health to establish the regulatory infrastructure for NOR facilities.

Washington’s framework addresses the NOR process as a form of controlled aerobic decomposition. WA DOE guidance covers facility design, containment, and the environmental handling of materials and outputs. Because Washington has had operational NOR facilities since 2020, its regulatory framework has been tested against real-world operations — making it the most mature model available for other states.

States that have more recently legalized or begun operationalizing NOR — including Colorado, Oregon, Nevada, Arizona, Maryland, Delaware, Minnesota, Maine, and Georgia — are developing their own frameworks, often referencing Washington’s model as a starting point. Visit the WA DOE NOR page (ecology.wa.gov) for Washington’s current guidance.

How Does NOR Permitting Differ From Cremation Permitting?

The differences between NOR and cremation on the environmental permitting side are meaningful:

Cremation air permits are more intensive. Crematories must obtain air quality permits specifically because cremation generates particulate matter and, when dental amalgam fillings are present, mercury vapor. State environmental agencies regulate these emissions closely, and crematories must demonstrate that their equipment meets emission standards.

NOR’s air impact is lower. The NOR process generates CO₂ and water vapor through aerobic biological decomposition — the same outputs as a large-scale composting operation. These outputs are not regulated at the same level as cremation emissions, which simplifies the air quality permitting process for NOR facilities.

NOR may face more novel regulatory questions. Because NOR is newer, some state environmental agencies are working through questions that have no direct precedent — for example, how to classify the finished soil for agricultural or horticultural use, or how to address the handling of soil from individuals who died with certain communicable diseases. These questions are being addressed on a state-by-state basis.

How Are Permitting Responsibilities Split Between State, Local, and Federal Authorities?

Environmental permits for NOR facilities are issued at the state level — not the federal level. The U.S. Environmental Protection Agency (EPA) does not have a specific permitting program for NOR facilities as of 2026. EPA’s general guidance on composting and biosolids management can inform state-level frameworks, but no federal NOR-specific permit exists.

Within states, some environmental permit functions are delegated to county or local agencies. Operators should expect to engage with multiple regulatory bodies — state environmental agencies, state health departments, and potentially local planning and zoning boards — before opening a facility.

What Do These Permitting Requirements Mean for NOR Operators?

If you are exploring adding NOR to your funeral home, environmental permitting is one of the first regulatory conversations you need to have — not the last. The time to engage your state environmental agency is before equipment is installed and before facility construction begins. Retroactive permitting is difficult and can result in costly modifications or delays.

Key steps for operators approaching environmental permitting:

Identify the lead environmental agency in your state for NOR (in Washington, this is WA DOE; in Colorado, this is the Colorado Department of Public Health and Environment, CDPHE; in Oregon, it is the Oregon Department of Environmental Quality).
Request a pre-application meeting to understand what permits are required before submitting any applications.
Engage a facilities engineer or environmental consultant familiar with composting or decomposition-based facility permitting — NOR permitting shares significant common ground with commercial composting regulation.
Coordinate with your state health department simultaneously, as NOR facility licensing typically spans both the environmental and health regulatory tracks.

TerraCare Partners works with operators navigating permitting and operational setup. If you have questions about what permitting looks like in your state, reach out to our team.

For consumers, regulated environmental permits are part of the quality and safety framework. When evaluating a terramation provider, it is entirely reasonable to ask whether the facility holds all required state environmental permits and whether those permits are in good standing. Providers with nothing to hide will answer that question directly.

Does the EPA regulate terramation facilities?

Not directly. The EPA has no NOR-specific permitting program as of 2026. NOR facilities are regulated by state environmental agencies — such as Washington State’s Department of Ecology or Colorado’s DPHE — which may draw on EPA guidance for composting and biosolids management when developing their frameworks.

Do NOR facilities need air quality permits?

It depends on the state. The NOR process produces CO₂ and water vapor — not regulated pollutants at levels typical of NOR operations. However, some states require facilities to register with the state environmental agency under general air quality compliance requirements. The air permitting burden for NOR is substantially lighter than for crematories, which must control particulate matter and mercury emissions.

Can a terramation facility open without environmental permits?

No. Operating without required environmental permits exposes a facility to significant legal and regulatory consequences, including fines, license revocation, and forced closure. Environmental permits are not optional — they are part of the licensing framework that allows NOR facilities to operate legally.

How do I find out what environmental permits my state requires for NOR?

Contact your state’s lead environmental agency directly. In Washington, that is the Department of Ecology (ecology.wa.gov). In Colorado, the Department of Public Health and Environment (cdphe.colorado.gov). In Oregon, the Department of Environmental Quality (oregon.gov/deq). Other states are developing their frameworks as NOR operations begin — your state environmental agency’s solid waste or composting division is usually the right starting point.
