(2) In carrying out the provisions of subsection (1) of this section, the commission may grant specific variances from particular requirements or may grant a permit to an applicant or to a class of applicants or to a specific disposal site, and specify conditions it considers necessary to protect the public health.

(3) The commission shall grant a variance only if:

(a) Conditions exist that are beyond the control of the applicant.

(b) Special conditions exist that render strict compliance unreasonable, burdensome or impractical.

(c) Strict compliance would result in substantial curtailment or closing of a disposal site and no alternative facility or alternative method of solid waste management is available.

(4) A variance may be revoked or modified by the commission after a public hearing held upon not less than 10 days’ notice. Such notice shall be served upon all persons who the commission knows will be subjected to greater restrictions if such variance is revoked or modified, or who are likely to be affected or who have filed with the commission a written request for such notification.

(5) In addition to the authority to issue a variance under subsections (1) to (4) of this section, the commission may modify an existing disposal site permit to specify the conditions under which the disposal site may accept and dispose of infectious waste. The commission also may require that an energy recovery facility or solid waste incinerator accept infectious waste generated in Oregon if the infectious waste has been contained and transported in accordance with ORS 459.390 and 825.256, but only so long as the volume of infectious waste generated outside the county in which the facility or incinerator is located does not affect the ability of the facility or incinerator to process or dispose of all waste generated within the county in which the facility or incinerator is located. As used in this subsection, "infectious waste" has the meaning given that term in ORS 459.386.

(6) The establishment, operation, maintenance, expansion, alteration, improvement or other change of a disposal site in accordance with a variance is not a violation of ORS 459.005 to 459.105 and 459.205 to 459.385 or any rule or regulation adopted pursuant thereto.
