Each topic in each resource report must be addressed or its omission justified, unless the data is not required for that type of proposal. If material required for one resource report is provided in another resource report or in another exhibit, it may be cross referenced. If any resource report topic is required for a particular project but is not provided at the time the application is filed, the environmental report must explain why it is missing and when the applicant anticipates it will be filed.

( 3 ) *Supporting design report.* The applicant must submit, at a minimum, the following supporting information to demonstrate that existing and proposed structures are safe and adequate to fulfill their stated functions and must submit such information in a separate report at the time the application is filed: ( i ) An assessment of the suitability of the locations of proposed transmission line towers, substations, and appurtenant structures based on geological and subsurface investigations, including investigations of soils and rock borings and tests evaluating all foundations and construction materials;
( ii ) Copies of boring logs, geology reports, and laboratory test reports;
( iii ) An identification of all borrow areas and quarry sites and an estimate of required quantities of suitable construction material; and
( iv ) Stability and stress analyses for all major transmission structures and conductors under all probable loading conditions, including seismic, wind, and ice loading, as appropriate, in sufficient detail to permit independent staff evaluation.
( 4 ) The applicant must submit the supporting design report described in paragraph (p)(3) of this section at the time preliminary and final design drawings are filed. If the report contains preliminary drawings, it must be designated as a “Preliminary Supporting Design Report.”
