Introduction
(1)
Monitoring wells and geotechnical holes drilled to allow ground water and geologic determinations are constructed in a variety of environments and under a variety of conditions. Improper construction, maintenance, operation, and abandonment can allow deterioration of ground water quality and supply. Although enforcement actions may be exercised against other parties, the landowner of the property where the monitoring well or geotechnical hole is constructed is ultimately responsible for the condition, use, maintenance, conversion, and abandonment of the monitoring well, or geotechnical hole.(2)
Holes other than monitoring wells, water supply wells, or geotechnical holes which are drilled, excavated, or otherwise constructed in the earth’s surface can also provide an avenue for deterioration of ground water quality. Improper construction, maintenance, use, and abandonment of other holes can pose a significant risk to ground water. Table 240-1 lists common subsurface borings and indicates which administrative rule governs the construction, conversion, maintenance, alteration, and abandonment of the boring.(3)
Ground water problems are difficult, expensive, and time consuming to correct. The Water Resources Commission (Commission) has been authorized to develop standards for wells drilled for the purpose of monitoring ground water in order to protect the state’s ground waters. The Commission has also been authorized to develop standards for other holes through which ground water may become contaminated. The rules set forth herein are adopted to provide that protection. Their purpose is to prevent and eliminate ground water contamination, waste, and loss of artesian pressure.(4)
The Commission may develop additional rules as needed prescribing standards for the construction, operation, maintenance, and abandonment of other specific types of wells and holes to protect ground water.(5)
Except for the Commission’s power to adopt rules, the Commission may delegate to the Water Resources Director the exercise or discharge in the Commission’s name of any power, duty or function of whatever character, vested in or imposed by law upon the Commission. The official act of the Director acting in the Commission’s name and by the Commission’s authority shall be considered to be an official act of the Commission. The Commission delegates to the Director full authority to act in the Commission’s name where that delegation is reflected in these rules.(6)
Under the provisions of ORS 537.780 (Powers of Water Resources Commission), the Commission is authorized to adopt such procedural rules and regulations as deemed necessary to carry out its function in compliance with the Ground Water Act of 1955. In fulfillment of these responsibilities and to ensure the preservation of the public welfare, safety, and health, the Commission has established these rules and regulations as the minimum standards for the construction, alteration, abandonment, conversion, and maintenance of monitoring wells in Oregon.(7)
Monitoring wells are wells as defined in ORS 537.515 (Definitions for ORS 537.505 to 537.795 and 537.992)(9). A license and licensing fee, bond, examination, well report, and start card are required for construction, conversion, alteration, or abandonment of a monitoring well. In addition, a start card fee is required for new construction, deepening a well, and conversion.(8)
To protect the ground water resource, the Commission has the authority to regulate geotechnical holes under ORS 537.780 (Powers of Water Resources Commission)(1)(c)(A). Construction of geotechnical holes requires either a Water Supply Well Constructor or Monitoring Well Constructor’s License or Oregon registration as a geologist or civil engineer. If any one of the criteria in OAR 690-240-0035 (Geotechnical Holes: General Performance and Responsibility Requirements)(2)(a)–(d) is met, a geotechnical hole report must be submitted.(9)
To protect the ground water resource, the Commission has the authority, under ORS 537.780 (Powers of Water Resources Commission)(1)(c)(A), to regulate any hole through which ground water may be contaminated. Construction of holes other than water supply wells and monitoring wells does not require a license and licensing fee, bond, examination, well report, start card, and start card fee.(10)
Holes constructed under ORS Chapters 517, 520, and 522, and rules promulgated from those statutes, are the responsibility of the Oregon Department of Geology and Mineral Industries and are not subject to these rules. These include, but are not limited to, holes constructed for the purposes of exploring for, or producing, petroleum, minerals, or geothermal resources.(11)
The rules and regulations set forth herein shall become effective upon adoption by the Water Resources Commission.(12)
Under no circumstances shall a monitoring well, piezometer, geotechnical hole, or other hole be constructed in a manner that allows commingling or leakage of ground water by gravity flow or artesian pressure from one aquifer to another. (See definition of aquifer.)(13)
The rules and regulations set forth herein provide the minimum standards for the construction, conversion, alteration, maintenance, and abandonment of monitoring wells, geotechnical holes, and other holes. After the effective date of adoption of these rules and regulations, no monitoring well, geotechnical hole, or other hole shall be constructed, altered, converted, or abandoned contrary to the provisions of these rules and regulations without prior approval from the Water Resources Department. Violation of these standards may result in enforcement under OAR chapter 690, division 240, including suspension or revocation of a constructor’s license, imposition of civil penalties on the landowner or constructor, action on a bond, or other sanctions authorized by law.
