State rules

Oregon

Oregon licenses well constructors through the Water Resources Department. The department's exam page says the water and monitoring well constructor examination is held the second Monday of January, April, July, and October at the department in Salem. To take the exam, a person must be at least 18, submit an application, and pay the $25 exam fee printed on that page. The study materials cover Oregon well statutes and rules, groundwater, drilling tools, start cards, and well logs. A license lasts two years and expires on June 30. The department's renewal page says the renewal fee is $165, with a late fee if renewal is after expiration, and that continuing education must be met or the license cannot be renewed. This record does not list constructors.

The Secretary of State's license directory describes the water supply well constructor license as a two-year license expiring June 30, with a $165 license fee, and it states a surety bond or irrevocable letter of credit of $20,000. The department's renewal page says a license may be renewed before it expires and not later than one year after it expires. A person who renews in that late year pays a late fee. If the license is not renewed within 12 months, the person must retake the exam. The exam page prints the Salem office at 725 Summer Street NE, Suite A, Salem, OR 97301, and the phone 503-986-0900.

Start cards and well logs are part of what the exam tests. The department's constructor pages are the place to see the current start-card and well-report instructions. A property owner should ask for the constructor's license number and should ask whether the license is for water supply wells, monitoring wells, or both. The bond or letter of credit is a condition the license directory states for the water supply constructor license. This record does not copy individual constructors from any lookup. The $25 exam fee, the $165 renewal fee, and the $20,000 bond are printed on the state pages cited here and are not stored in the fee field.

Monitoring well applicants are tested on the monitoring well rules in addition to the water-supply statutes. The exam is closed in the sense that the department provides the rules at the exam, according to the study packet, and it is held in Salem only. Someone hiring a constructor should confirm the license is inside its two-year term and that continuing education was completed before the June 30 expiration. The department's constructor resources page is the index for the exam, the renewal, and the bond form.
