A. Sierra County may appoint such agents and/or assign such county personnel as the Board of Supervisors may from time to time authorize to inspect watercraft prior to launching into the waters of Sierra County to detect the presence and prevent the introduction of aquatic invasive species. When inspection is required by any such duly authorized agent or county personnel, no person may launch a watercraft without first submitting to an inspection under this section.

B. Any watercraft inspected pursuant to subsection (A) of this section that is found to have indicia of contamination by aquatic invasive species may be required to undergo decontamination prior to launch, pursuant to such decontamination procedures and requirements that shall be prescribed by the Board of Supervisors. Prior to launch, any watercraft having undergone decontamination procedures will be subject to such inspection and certification requirements as may from time to time be duly established by the Board of Supervisors.

C. Prior to launching any watercraft into waters in Sierra County, and/or at the time of the inspection, the person seeking to launch the watercraft may be required to execute an affidavit indicating whether the watercraft has been operated in any waters known to contain aquatic invasive species and, if so, providing the date(s) of said operation, the length of time that the watercraft has been continuously stored in a drained and dry condition subsequent to being on a water body containing aquatic invasive species, and what decontamination procedures, if any, the watercraft has undergone. Where required, the affidavit shall be on a form provided by the county and shall contain a list of waters known to contain aquatic invasive species. The affidavit shall be signed under penalty of perjury.

D. No person shall be required to submit a watercraft to inspection under this section. If the watercraft owner or operator refuses to consent to screening, that watercraft shall not be allowed to launch in any water body within Sierra County and shall be in violation of this chapter if he/she should nonetheless attempt to or actually launch in any water body in Sierra County.
