Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
						Identify Potential Impairment--Dischargers shall provide in the report of waste
						discharge ("ROWD", including any such report integrated into a Joint Technical
						Document (JTD), pursuant to §
												21585) an analysis describing how
						the ground and surface water could affect the Unit and how the Unit, including
						how any waste, if it escapes from the Unit, could affect the beneficial uses of
						ground water bodies (including, but not limited to, any aquifers underlying the
						facility) and surface water bodies. The RWQCB shall use this information to
						determine the suitability of the Unit with respect to ground water protection
						and avoidance of geologic hazards and to demonstrate that the Unit meets the
						classification criteria set forth in Article 3, Subchapter 2, Chapter 3,
						Subdivision
						1 of this division (§
												20240 et seq.).
(b) Support Proposed
						Classification--Dischargers shall provide the data required by this section
						regarding the physical characteristics of the Unit and the surrounding region
						in order to demonstrate suitability for the appropriate Unit classification.
						The ROWD shall present this information in understandable written, tabular, and
						graphic format, as appropriate, and this information shall be at a level of
						detail appropriate to support the RWQCB's approving the Unit's proposed
						classification. Maps, plans, diagrams, and other graphics shall be prepared to
						appropriate scale and each shall include a legend identifying the information
						presented. All sources of data shall be identified.
(c) Restate, Where Appropriate--If a report
						submitted by a discharger refers to another source, the relevant information
						from that source shall be restated in the report. If the source is not
						generally available, the relevant portion(s) of the source shall be included
						verbatim in the report as an appendix.
(d) Topography.
(1) Topographic Map--A map of the Unit and
						its surrounding region within one mile of the perimeter of the Unit, showing
						elevation contours, natural ground slopes, drainage patterns, and other
						topographic features.
(2)
						Floodplain--Identification of whether the facility is located within a 100-year
						floodplain. This identification must indicate the source of data for such
						determination and include a copy of the relevant Federal Emergency Management
						Agency (FEMA) flood map, if used, or the calculations and maps used where a
						FEMA map is not available. The submittal shall also identify the 100-year
						floodplain 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. Dischargers having
						facilities located in the 100-year floodplain shall provide the following
						information:
(A) engineering analysis to
						indicate the various hydrodynamic and hydrostatic forces expected to result at
						the site as consequence of a 100-year flood;
(B) structural or other engineering studies
						showing the design of Units and flood protection devices (
e.g.,
						floodwalls, dikes
) at the facility and how these will prevent washout;
						and
(C) landfills accepting
						municipal solid waste shall demonstrate that:
1. for Class II landfills, the Unit meets the
						flooding requirements of §
															20250(c);
						or
2. for Class III landfills, the
						Unit meets the requirements of §
															20260(c).
