Or. Admin. Code § 690-240-0006

Current through Register Vol. 63, No. 12, December 1, 2024

Section 690-240-0006 - Special Standards

(1) Site conditions may require specific design, construction, and abandonment procedures to adapt to the existing local geologic and ground water conditions to fully utilize every natural protection to the state's ground water. Specific site conditions may require different design, construction, setback, or abandonment standards than required by the Monitor Well or Geotechnical Hole construction rules. Alternative technologies or methods not addressed in these rules may also exist which could be effectively utilized in the construction or abandonment of a monitoring well or geotechnical hole. Prior to the completion of the well, a bonded constructor must request and receive approval from the Department to use methods or materials that do not meet the monitoring well or geotechnical hole construction standards. The Department may approve such requests either orally or in writing. If oral approval is granted, the written request must be submitted to the Department within three working days of the date of the oral approval. Failure to submit a written request as described above may void the prior oral approval. The proposed methods or materials shall provide at least the same level of resource protection as that which is provided by these rules.

(2) The written request for special standards shall include:

(a) Name, license number and signature of the bonded well constructor;

(b) Location of the well by county, township, range, section, tax-lot (if assigned), 1/4, 1/4 section, and Latitude and Longitude as established by a global positioning system;

(c) Name and address of landowner;

(d) Address of the project/well site;

(e) Type of work;

(f) The reasons(s) that conformance to the rules and regulations for monitoring wells or geotechnical holes cannot be met;

(g) A diagram and written description showing the proposed monitoring well or geotechnical hole's design, construction, or abandonment;

(h) The well identification number, if assigned;

(i) The start card number;

(j) If the request is to abandon a monitoring well in-place, then the most current water quality analytical data shall also be provided;

(k) Oregon Department of Environmental Quality site or facility identification number and no further action (NFA) decision, if applicable; and

(l) Any associated well report numbers if special standard request is for alteration or abandonment.
