# 601.20 Streamlining Environmental Impact Statements.

The NCPC as Lead Agency shall use all available techniques to minimize the length of an EIS. Such techniques include, without limitation, drafting an EIS in clear, concise language; preparing an analytic vs. encyclopedic EIS; reducing emphasis on background information; using the scoping process to emphasize significant issues and de-emphasize non-significant issues; incorporating relevant information by reference; using a programmatic EIS and tiering to eliminate duplication in subsequent EISs; and following the format guidelines of § 601.22.
