Total time for a Negative Declaration, from complete application to adoption of the Negative Declaration = 180 days maximum (PRC 21151.5, Guidelines 15107)

Total time for an EIR, from complete application to certification of the EIR = 1 year maximum (PRC 21151.5, Guidelines 15108)

PRC Section 21151.5 allows a "reasonable extension" of these periods when agreeable to both the lead agency and the project applicant, and when compelling circumstances exist. Guidelines Section 15108 defines this for EIRs as one 90-day extension.

Guidelines Section 15109 provides that the running of these time periods may be suspended when there is "unreasonable delay" by the applicant in providing to the lead agency material necessary to complete the Negative Declaration or EIR.
