Enabling Sustainable Data Center Growth

The most critical risks are often the least visible at the outset. Wetlands, floodplains, endangered species habitat and cultural resources can trigger complex permitting under frameworks like the Endangered Species Act (ESA) or National Historic Preservation Act (NHPA). Where a federal nexus exists, National Environmental Policy Act (NEPA) review can introduce significant timeline uncertainty, particularly if alternatives analysis or mitigation is required.

Onterris combines targeted analysis, field verification and early agency coordination to identify fatal flaws early and clarify permitting pathways before capital is committed.

Power availability is only part of the equation. Behind-the-meter or backup power generation can introduce more complicated permitting pathways under the Clean Air Act, especially in nonattainment designations or areas where projects face heightened community scrutiny.

Onterris evaluates energy sourcing, emissions considerations and permitting requirements upfront, using data and analysis to clarify thresholds, reduce uncertainty and prevent delays later in development.

Water use and cooling strategies at data centers are under increasing scrutiny. Large water withdrawals may require state-level approvals, while discharges fall under the Clean Water Act’s NPDES program. Regulators also assess thermal impacts, chemical treatment and effects on receiving waters, all of which can add complexity to permitting.

Onterris connects water sourcing, discharge requirements and system performance analysis to design solutions that are operationally efficient, approvable and sustainable.
