25400.16.  (a) Property contaminated by methamphetamine laboratory
activity is safe for human occupancy for purposes of this chapter
only if the level of methamphetamine on an indoor surface is less
than, or equal to, 1.5 micrograms per 100 square centimeters.
   (b) Except as provided in subdivision (c), if property is
contaminated by methamphetamine laboratory activity that included the
use of lead or mercury compounds, in addition to the requirements of
subdivision (a), property is safe for human occupancy for purposes
of this chapter only if both of the following standards are met with
regard to that property:
   (1) The total level of lead is less than, or equal to, 20
micrograms per square foot.
   (2) The level of mercury is less than, or equal to, 50 nanograms
per cubic meter in air.
   (c) Subdivisions (a) and (b) shall become inoperative on the
effective date that the department, in consultation with the office,
adopts a health-based target remediation standard for methamphetamine
to determine when a property contaminated by methamphetamine
laboratory activity only is safe for human occupancy, in which case
any reference in this chapter to a human-occupancy standard specified
in this section shall mean only the health-based target remediation
standard for methamphetamine adopted by the department.
   (d) This section does not preclude the department, in consultation
with the Office of Health Hazard Assessment, from adopting stricter
health-based remediation standards than required under this section.
