A detailed environmental study required by CEPA to provide specific information to decision makers about a proposed project. Under CEPA, “historical resources” (see below) cannot be demolished or adversely altered without preparation of an EIE, which studies alternatives to the proposed project. A Draft EIE is the first document issued and gives the public the opportunity to submit comments. A Final EIE incorporates the responses to these public comments and is presented to the Sponsoring Agency for approval (or “certification”).
