(h) Section 4 is revised to read as follows:
“In addition to any responsibilities under this Order and Sections 102, 202, and 205 of the Flood Disaster Protection Act of 1973, as amended (42 U.S.C. 4012a, 4106, and 4128), agencies which guarantee, approve, regulate, or insure any financial transaction which is related to an area located in an area subject to the base flood shall, prior to completing action on such transaction, inform any private parties participating in the transaction of the hazards of locating structures in the area subject to the base flood.”.
(i) Section 6(c) is amended by striking “, including at a minimum, that area subject to a one percent or greater chance of flooding in any given year” and inserting in lieu thereof:
“. The floodplain shall be established using one of the following approaches:
“(1) Unless an exception is made under paragraph (2), the floodplain shall be:
“(i) the elevation and flood hazard area that result from using a climate-informed science approach that uses the best-available, actionable hydrologic and hydraulic data and methods that integrate current and future changes in flooding based on climate science. This approach will also include an emphasis on whether the action is a critical action as one of the factors to be considered when conducting the analysis;
“(ii) the elevation and flood hazard area that result from using the freeboard value, reached by adding an additional 2 feet to the base flood elevation for non-critical actions and by adding an additional 3 feet to the base flood elevation for critical actions;
“(iii) the area subject to flooding by the 0.2 percent annual chance flood; or
“(iv) the elevation and flood hazard area that result from using any other method identified in an update to the FFRMS.
“(2) The head of an agency may except an agency action from paragraph (1) where it is in the interest of national security, where the agency action is an emergency action, where application to a Federal facility or structure is demonstrably inappropriate, or where the agency action is a mission-critical requirement related to a national security interest or an emergency action. When an agency action is excepted from paragraph (1) because it is in the interest of national security, it is an emergency action, or it is a mission-critical requirement related to a national security interest or an emergency action, the agency head shall rely on the area of land subject to the base flood”.
(j) Section 6 is further amended by adding the following new subsection (d) at the end:
“(d) The term 'critical action' shall mean any activity for which even a slight chance of flooding would be too great.”.
(k) Section 8 is revised to read as follows:
“Nothing in this Order shall apply to assistance provided for emergency work essential to save lives and protect property and public health and safety, performed pursuant to Sections 403 and 502 of the Robert T. Stafford Disaster Relief and Emergency Assistance Act of 1988 (42 U.S.C. 5170b and 5192).”.
