We facilitate meaningful consultation with Tribes/First Nations, agencies, stakeholders, and the public to build trust, address concerns, and reduce project risks.

Environmental Assessment & Permitting FAQ

An EA evaluates the potential environmental, social, and cultural impacts of a proposed project and identifies ways to mitigate those impacts. In the U.S., this is primarily governed by NEPA and state equivalents, while in Canada it is governed federally under the Impact Assessment Act and provincially through specific environmental assessment laws.

Permitting ensures a project complies with all applicable environmental regulations before construction or operations can begin. This includes permits related to air, water, wetlands, wildlife, and cultural resources. Without proper permitting, projects risk delays, fines, or legal challenges.

We help clients build strong, transparent relationships with regulators, Tribal/First Nations governments, and other stakeholders. Our team facilitates consultation meetings, prepares defensible documentation, and develops strategies to address concerns proactively.

Projects across energy, infrastructure, mining, manufacturing, real estate development, and natural resource industries often require assessment and permitting. The scope depends on project location, size, and potential impacts to air, water, land, and communities.

Trinity offers a unique blend of technical expertise, regulatory knowledge, and facilitation skills. Our science-based, defensible work helps clients meet rigorous requirements in both the U.S. and Canada, while keeping projects on schedule and within budget.
