Section 340-094-0140 - Financial Assurance Criteria

If a municipal solid waste landfill is subject to 40 CFR, Part 258 as provided in40 CFR, § 258.1, the owner or operator shall comply with financial assurance criteria in40 CFR, Part 258, Subpart G. All municipal solid waste permittees shall also comply with this rule.

(1) Financial Assurance Required. The owner or operator of a municipal solid waste landfill shall maintain a financial assurance plan with detailed written cost estimates of the amount of financial assurance that is necessary and shall provide evidence of financial assurance for the costs of:

(a) Closure of the municipal solid waste landfill;

(b) Post-closure maintenance of the municipal solid waste landfill; and

(c) Any corrective action required by the Department to be taken at the municipal solid waste landfill, pursuant to OAR 340-094-0080(3).

(2) Exemptions. The Department may exempt from the financial assurance requirements existing municipal solid waste landfills which stopped receiving waste before October 9, 1993 (or which stopped receiving waste before April 9, 1994, if a "small landfill" meeting criteria in40 CFR, § 258.1(e)(2), and completed installation of final cover by October 9, 1994. The Department may also exempt from the financial assurance requirements an existing "very small landfill serving certain small communities" meeting criteria in40 CFR, § 258.1(f)(1), if such a landfill stops receiving waste before October 9, 1997 and completes installation of final cover by October 9, 1998.

(a) Exemption criteria. To be eligible for this exemption, the applicant shall demonstrate to the satisfaction of the Department that the site meets all of the following criteria and that the site is likely to continue to meet all of these criteria until the site is closed in a manner approved by the Department:

(A) The landfill poses no significant threat of adverse impact on groundwater or surface water;

(B) The landfill poses no significant threat of adverse impact on public health or safety;

(C) No system requiring active operation and maintenance is necessary for controlling or stopping discharges to the environment;

(D) The area of the landfill that has been used for waste disposal and has not yet been properly closed in a manner acceptable to the Department is less than and remains less than two acres or complies with a closure schedule approved by the Department.

(b) In determining if the applicant has demonstrated that a site meets the financial assurance exemption criteria, the Department will consider existing available information including, but not limited to, geology, soils, hydrology, waste type and volume, proximity to and uses of adjacent properties, history of site operation and construction, previous compliance inspection reports, existing monitoring data, the proposed method of closure and the information submitted by the applicant. The Department may request additional information if needed;

(c) An exemption from the financial assurance requirement granted by the Department will remain valid only so long as the site continues to meet the exemption criteria in subsection (2)(a) of this rule. If the site fails to continue to meet the exemption criteria, the Department may modify the closure permit to require financial assurance.

(3) Schedule for provision of financial assurance:

(a) For costs associated with the "worst-case" closure plan and the "Subtitle D" post-closure plan prepared pursuant to40 CFR, Subparts F and Gand OAR 340-094-0010(1)(a)(A) and OAR 340-094-0115(1)(a), respectively: Evidence of the required financial assurance for closure and post-closure maintenance of the landfill shall be provided on the following schedule:

(C) For other municipal solid waste landfills operating under a solid waste permit on November 4, 1993: by April 9, 1997; or
