REGULATIONS PERTAINING TO NPDES AND WPCF PERMITS
Initiation Level Rule
340-045-0100
(1) Definitions. The definitions in ORS 468B.138 are adopted by reference. In addition, for purposes of this rule, the following definitions apply:
(a) “Persistent Pollutants” are substances that are toxic and that either persist in the environment or accumulate in the tissues of humans, fish, wildlife or plants, and are listed in Column 2 of Table A.
(b) “Permittee” means a municipality in possession of a National Pollutant Discharge Elimination System or water pollution control facility permit issued by the DEQ pursuant to ORS 468B.050 for a sewage treatment facility that has a dry weather design flow capacity of one million gallons per day or more.
(c) “Initiation level” is the concentration of a persistent pollutant in a permittee’s effluent that, if exceeded, necessitates the preparation of a persistent pollutant reduction plan under ORS 468B.140.
(2) Initiation levels.
(a) Initiation levels for persistent pollutants are those values contained in Table A, or the analytical quantitation limit (concentration at which quantitative results can be reported with a high degree of confidence), whichever is higher.
(b) Initiation levels are not standards of quality and purity for the waters of this state for the purposes of ORS 468B.048 or the federal Clean Water Act.
(c) Except as specified in subsection (f), each permittee must measure the concentration of the persistent pollutants listed in Table A in its effluent, compare the results of these measurements to the initiation levels, determine whether any persistent pollutant exceeds its initiation level, and document this proposed determination in a report to the Department. For existing permittees, the report must be filed no later than 60 calendar days after receipt of laboratory results. For permittees that first become subject to this rule after its effective date, the report must be filed within 18 months after the permittee becomes subject to the rule.
(d) The Department will review this report to verify that the proposed determination is based on reliable information. If the Department finds that the proposed determination is not based on reliable information, the Department will make an independent determination of whether a initiation level has been exceeded.
(e) Each permittee must prepare and submit to the Department a written persistent pollutant reduction plan in accordance with ORS 468B.140(1)(a) addressing persistent pollutants that exceed the initiation level. For existing permittees, the plan must be submitted no later than July 1, 2011. For permittees that first become subject to this rule after the effective date of this rule, the plan must be submitted to the Department within six months after the report is submitted, or, if the Department makes an independent determination, six months from the date of the Department’s independent determination or within a timeframe established by the Department.
(f) The Department may suspend, by written order, the requirement to measure or develop a persistent pollutant reduction plan for a listed persistent pollutant if the Department determines it is not technically practicable to measure the pollutant in effluent or if the Department removes a pollutant from the Priority Persistent Pollutant List. If, based on additional monitoring done pursuant to a persistent pollutant reduction plan, the Department determines that it is unlikely that a pollutant exists in a permittee’s effluent, the Department may allow the permittee to withdraw the pollutant from inclusion in the persistent pollutant reduction plan.
