(I) Failure to submit a complete or accurate fuel pathway application or annual or quarterly report in a timely manner;
(II) Failure to conduct or complete third-party verification as required by this chapter; or
(III) Any other violation of this chapter.
(D) A responsible entity may file petition with ecology to resolve disagreement with the verification body on the requirements of this chapter.
(ii) Reverification requirements.
(A) If a verification body submits a positive or qualified positive verification statement to ecology, ecology may reject and set aside the submitted validation or verification statement and require the applicable responsible entity to have a CFS report or fuel pathway application reverified by a different verification body within 90 days if:
(I) Ecology finds an unacceptable level of conflict of interest according to WAC 173-424-850(2);
(II) Ecology finds a potential conflict of interest has arisen between the responsible entity and the verification body or any verifier engaged by the responsible entity to perform verification through monitoring as required under WAC 173-424-850(8);
(III) Ecology makes a determination that any of the bases for modification, suspension, or revocation of ecology approval under WAC 173-424-840(10) for a verification body or verifier engaged by the responsible entity to perform verification have occurred, and impacted the verification services provided, or impacted the verification statement(s) submitted to ecology;
(IV) An error is identified that affects the credit or deficit calculations in a CFP report(s) or fuel pathway application(s) submitted under this chapter; or
(V) A report that received a positive or qualified positive verification statement fails ecology verification or audit under (e) of this subsection.
(B) If ecology identifies an error and determines that the error does not affect the credit or deficit calculations in a CFP report or fuel pathway application, a correction may be made by the responsible entity without ecology set aside of the positive or qualified positive verification statement.
(C) A verification body may not continue to provide verification services to a responsible entity, and the responsible entity must have any report(s) or fuel pathway application(s) verified by a different verification body, upon receiving notification from the verification body with which it is currently engaged to provide verification services of either of the following:
(I) A modification to ecology approval of the verification body or any members of the verification team that is relevant to the verification services being performed; or
(II) Suspension or revocation of ecology approval of the verification body or any members of the verification team.
(D) A responsible entity that must have a report or fuel pathway application verified by a different verification body according to (d)(ii)(C) of this subsection may contact ecology to request an extension if it believes it cannot meet the applicable verification deadline under WAC 173-424-810(3) and it must receive written approval from ecology of any extended deadline(s).
(e) Data requests and audits.
(i) Ecology data requests and audits of responsible entity.
(A) Upon written request by ecology, the responsible entity must provide the data used to generate the application or report including all data available to the verification team in the conduct of validation or verification services, within 14 days of ecology's request.
(B) Upon written notification by ecology, the responsible entity must make itself, its personnel, and other entities in its feedstock and finished fuel supply chain, as applicable, available for an ecology audit.
(ii) Ecology data requests and audits of verification bodies.
(A) Upon request by ecology, the verification body must provide ecology the validation or verification report given to the responsible entity, as well as the sampling plan, contracts for verification services, and any other supporting documents and calculations, within 14 days.
(B) Upon written notification by ecology, the verification body must make itself and its personnel available for an ecology audit.
