(b) Establishment of flood loss allocation formula for indeterminate claims

(1) In general
Not later than 180 days after the date on which the protocol is established under section 3611(c)(1) of title 33, the Secretary, acting through the Administrator and in consultation with the Under Secretary, shall establish by rule a standard formula to determine and allocate wind losses and flood losses for claims involving indeterminate losses.

(2) Contents
The standard formula established under paragraph (1) shall—

(A) incorporate data available from the Coastal Wind and Water Event Database established under section 3611(f) of title 33;

(B) use relevant data provided on the National Flood Insurance Program Elevation Certificate for each indeterminate loss for which the formula is used;

(C) consider any sufficient and credible evidence, approved by the Administrator, of the pre-event condition of a specific property, including the findings of any policyholder or insurance claims adjuster in connection with the indeterminate loss to that specific property;

(D) include other measures, as the Administrator considers appropriate, required to determine and allocate by mathematical formula the property damage caused by flood or storm surge associated with a named storm; and

(E) subject to paragraph (3), for each indeterminate loss, use the post-storm assessment to allocate water damage (flood or storm surge) associated with a named storm.

(3) Degree of accuracy required
The standard formula established under paragraph (1) shall specify that the Administrator may only use the post-storm assessment for purposes of the formula if the Under Secretary certifies that the post-storm assessment has a degree of accuracy of not less than 90 percent in connection with the specific indeterminate loss for which the assessment and formula are used.

(c) Authorized use of post-storm assessment and COASTAL Formula

(1) In general
Subject to paragraph (3), the Administrator may use the post-storm assessment and the COASTAL Formula to—

(A) review flood loss payments for indeterminate losses, including as part of the quality assurance reinspection program of the Federal Emergency Management Agency for claims under the national flood insurance program and any other process approved by the Administrator to review and validate payments under the national flood insurance program for indeterminate losses following a named storm; and

(B) assist the national flood insurance program to—

(i) properly cover qualified flood loss for claims for indeterminate losses; and

(ii) avoid paying for any loss or damage to property caused by any peril (including wind), other than flood or storm surge, that is not covered under a standard policy under the national flood insurance program.

(2) Federal disaster declaration
Subject to paragraph (3), in order to expedite claims and reduce costs to the national flood insurance program, following any major disaster declared by the President under section 5170 of this title relating to a named storm in a coastal State, the Administrator may use the COASTAL Formula to determine and pay for any flood loss covered under a standard insurance policy under the national flood insurance program, if the loss is an indeterminate loss.

(3) National Academy of Sciences evaluation

(A) Evaluation required

(i) Evaluation
Upon the issuance of the rule establishing the COASTAL Formula, and each time the Administrator modifies the COASTAL Formula, the National Academy of Sciences shall—

(I) evaluate the expected financial impact on the national flood insurance program of the use of the COASTAL Formula as so established or modified; and

(II) evaluate the validity of the scientific assumptions upon which the formula is based and determine whether the COASTAL formula ¹ can achieve a degree of accuracy of not less than 90 percent in allocating flood losses for indeterminate losses.

(ii) Report
The National Academy of Sciences shall submit a report containing the results of each evaluation under clause (i) to the Administrator, the Committee on Banking, Housing, and Urban Affairs and the Committee on Commerce, Science, and Transportation of the Senate, and the Committee on Financial Services and the Committee on Science, Space, and Technology of the House of Representatives.

(B) Effective date and applicability

(i) Effective date
Paragraphs (1) and (2) of this subsection shall not take effect unless the report under subparagraph (A) relating to the establishment of the COASTAL Formula concludes that the use of the COASTAL Formula for purposes of paragraph ² (1) and (2) would not have an adverse financial impact on the national flood insurance program and that the COASTAL Formula is based on valid scientific assumptions that would allow a degree of accuracy of not less than 90 percent to be achieved in allocating flood losses for indeterminate losses.

(ii) Effect of modifications
Unless the report under subparagraph (A) relating to a modification of the COASTAL Formula concludes that the use of the COASTAL Formula, as so modified, for purposes of paragraphs (1) and (2) would not have an adverse financial impact on the national flood insurance program and that the COASTAL Formula is based on valid scientific assumptions that would allow a degree of accuracy of not less than 90 percent to be achieved in allocating flood losses for indeterminate losses the Administrator may not use the COASTAL Formula, as so modified, for purposes of paragraphs (1) and (2).

(C) Funding
Notwithstanding section 4017 of this title, there shall be available to the Administrator from the National Flood Insurance Fund, of amounts not otherwise obligated, not more than $750,000 to carry out this paragraph.

(d) Disclosure of COASTAL Formula
Not later than 30 days after the date on which a post-storm assessment is submitted to the Secretary under section 3611(b)(2)(C) of title 33, for each indeterminate loss for which the COASTAL Formula is used pursuant to subsection (c)(2), the Administrator shall disclose to the policyholder that makes a claim relating to the indeterminate loss—

(1) that the Administrator used the COASTAL Formula with respect to the indeterminate loss; and

(2) a summary of the results of the use of the COASTAL Formula.

(f) Recordkeeping
Each consideration and measure the Administrator determines necessary to carry out subsection (b) may be required, with advanced approval of the Administrator, to be provided for on the National Flood Insurance Program Elevation Certificate, or maintained otherwise on record if approved by the Administrator, for any property that qualifies for the COASTAL Formula under subsection (c).

(g) Civil penalty

(1) In general
If an insurance claims adjuster knowingly and willfully makes a false or inaccurate determination relating to an indeterminate loss, the Administrator may, after notice and opportunity for hearing, impose on the insurance claims adjuster a civil penalty of not more than $1,000.

(2) Deposit
Notwithstanding section 3302 of title 31 or any other law relating to the crediting of money, the Administrator shall deposit in the National Flood Insurance Fund any amounts received under this subsection, which shall remain available until expended and be available to the Administrator for purposes authorized for the National Flood Insurance Fund without further appropriation.

(h) Rule of construction
Nothing in this subsection ³ shall be construed to require the Administrator to make any payment under the national flood insurance program, or an insurance company to make any payment, for an indeterminate loss based upon post-storm assessment or the COASTAL Formula.

(i) Applicability
Subsection (c) shall apply with respect to an indeterminate loss associated with a named storm that occurs after the date on which the Administrator issues the rule establishing the COASTAL Formula under subsection (b).

(j) Rule of Construction
