(A) the owner or operator of a new facility or a facility undergoing substantial modification (a Class 3 modification specified in section 66270.42(c) involving physical changes to the facility) shall demonstrate compliance with the seismic standard. This demonstration may be made using either published geologic data or data obtained from field investigations carried out by the applicant. The information provided shall be of such quality to be acceptable to geologists experienced in identifying and evaluating seismic activity. The information submitted shall show that either:
1. no faults which have had displacement in Holocene time are present, or no lineations which suggest the presence of a fault (which have displacement in Holocene time) within 3,000 feet of a facility are present, based on data from:
a. published geologic studies,
b. aerial reconnaissance of the area within a five-mile radius from the facility;
c. an analysis of aerial photographs covering a 3,000 foot radius of the facility, and
d. if needed to clarify the above data, a reconnaissance based on walking portions of the area within 3,000 feet of the facility, or
2. if faults (to include lineations) which have had displacement in Holocene time are present within 3,000 feet of a facility, no faults pass within 200 feet of the portions of the facility where treatment, storage or disposal of hazardous waste will be conducted, based on data from a comprehensive geologic analysis of the site. Unless a site analysis is otherwise conclusive concerning the absence of faults within 200 feet of such portions of the facility data shall be obtained from a subsurface exploration (trenching) of the area within a distance no less than 200 feet from portions of the facility where transfer, treatment, storage or disposal of hazardous waste will be conducted. Such trenching shall be performed in a direction that is perpendicular to known faults (which have had displacement in Holocene time) passing within 3,000 feet of the portions of the facility where transfer, treatment, storage or disposal of hazardous waste will be conducted. Such investigation shall document with supporting maps and other analyses, the location of faults found;
(B) owners and operators of all facilities shall provide an identification of whether the facility is located within a 100 year floodplain. This identification shall indicate the source of data for such determination and include a copy of the relevant Federal Insurance Administration (FIA) flood map, if used, or the calculations and maps used where an FIA map is not available. Information shall also be provided identifying the 100-year flood level and any other special flooding factors (e.g., wave action) which must be considered in designing, constructing, operating or maintaining the facility to withstand washout from a 100-year flood;
(C) where maps for the National Flood Insurance Program produced by the Federal Insurance Administration (FIA) of the Federal Emergency Management Agency are available, they will normally be determinative of whether a facility is located within or outside of the 100-year floodplain. However, where the FIA map excludes an area (usually areas of the floodplain less than 200 feet in width), these areas shall be considered and a determination made as to whether they are in the 100-year floodplain. Where FIA maps are not available for a proposed facility location, the owner or operator shall use equivalent mapping techniques to determine whether the facility is within the 100-year floodplain, and if so located, what the 100-year flood elevation would be;
(D) owners and operators of facilities located in the 100-year floodplain shall provide the following information:
1. engineering analysis to indicate the various hydrodynamic and hydrostatic forces expected to result at the site as consequence of a 100-year flood;
2. structural or other engineering studies showing the design of operational units (e.g., tanks, incinerators) and flood protection devices (e.g., floodwalls, dikes) at the facility and how these will prevent washout;
3. if applicable, and in lieu of subsections (b)(11)(D) l. and 2. of this section, a detailed description of procedures to be followed to remove hazardous waste to safety before the facility is flooded, including:
a. timing of such movement relative to flood levels, including estimated time to move the waste, to show that such movement can be completed before floodwaters reach the facility;
