California Code, Water Code - WAT § 13399.1

(a) The notice to comply is written in the course of conducting an inspection by an authorized representative of the state board or regional board.  If testing is required by the state board or regional board to determine compliance, and the testing cannot be conducted during the course of the inspection, the representative of the state board or regional board shall have a reasonable period of time to conduct the required testing.  If, after the test results are available, the representative of the state board or regional board determines that the issuance of a notice to comply is warranted, the representative shall immediately notify the facility owner or operator in writing.
