An unreasonable delay by an applicant in meeting requests by the lead agency necessary for the preparation of a negative declaration or an EIR shall suspend the running of the time periods described in Sections 15107 and 15108 for the period of the unreasonable delay. Alternatively, an agency may disapprove a project application where there is unreasonable delay in meeting requests. The agency may allow a renewed application to start at the same point in the process where the application was when it was disapproved.
