- [Reserved.] Note: These standards removed because they apply only to Class I Units
(see Chapter 15, Div. 3., Title 23, CCR).
- This category is defined in section 20250(a).
- This category is defined in section 20260(a).
- [Reserved.] Note: Left in Ch-15. Applies only to Class I Units.
- Exemption from siting criteria does not release dischargers from the obligation to
protect Units from the geologic or environmental hazards involved. Exemption is
conditioned on such protection.
- The term "Tidal Waves" includes tsunamis, seiches, and surge condition.
