(2) Comply with a civil, criminal, or regulatory inquiry, investigation, subpoena, or summons by federal, state, or local authorities. Law enforcement agencies, including police and sheriffs departments, may direct a business pursuant to a law enforcement agency-approved investigation with an active case number not to delete a consumer's personal information and upon receipt of such direction a business shall not delete the personal information for 90 days, in order to allow the law enforcement agency to obtain a court-issued subpoena, order, or warrant to obtain a consumer's personal information. For good cause and only to the extent necessary for investigatory purposes, a law enforcement agency may direct a business not to delete the consumer's personal information for additional 90 day periods. A business that has received direction from a law enforcement agency not to delete the personal information of a consumer who has requested deletion of the consumer's personal information shall not use the consumer's personal information for any purpose other than retaining it to produce to law enforcement in response to a court-issued subpoena, order, or warrant, unless the consumer's deletion request is subject to an exemption from deletion under this title.
