(2) No individual may be removed or temporarily suspended from unescorted access or be subjected to other administrative action based solely on an unconfirmed positive result from any drug test, other than for marijuana (THC) or cocaine, unless other evidence indicates that the individual is impaired or might otherwise pose a safety hazard. With respect to onsite initial screening tests for marijuana (THC) and cocaine, licensee management may be informed and licensees may temporarily suspend individuals from unescorted access or from normal duties or take lesser administrative actions against the individual based on an unconfirmed presumptive positive result provided the licensee complies with the following conditions
§ 26.27 Management actions and sanctions to be imposed.
b) Each licensee subject to this part shall, as a minimum, take the following actions. Nothing herein shall prohibit the licensee from taking more stringent action.
(1) Impaired workers, or those whose fitness may be questionable, shall be removed from activities within the scope of this part, and may be returned only after determined to be fit to safely and competently perform activities within the scope of this part.
(2) Lacking any other evidence to indicate the use, sale, or possession of illegal drugs onsite, a confirmed positive test result must be presumed to be an indication of offsite drug use. The first confirmed positive test must, as a minimum, result in immediate removal from activities within the scope of this part for at least 14 days and referral to the EAP for assessment and counseling during any suspension period. Plans for treatment, follow-up, and future employment must be developed, and any rehabilitation program deemed appropriate must be initiated during such suspension period. Satisfactory management and medical assurance of the individual's fitness to adequately perform activities within the scope of this part must be obtained before permitting the individual to be returned to these activities. Any subsequent confirmed positive test must result in, as applicable--
(i) Removal from unescorted access to nuclear power plant protected areas;
(ii) Removal from unescorted access to Category IA Material;
(iii) Removal from responsibilities to create or have access to records or procedures for safeguarding SSNM;
(iv) Removal from responsibilities to measure Category IA Material;
(v) Removal from the responsibilities of transporting or escorting Category IA Material;
(vi) Removal from the responsibilities of guarding Category IA Material at any other licensee facility; and
(vii) Removal from activities within the scope of this part for a minimum of 3 years from the date of removal.
(3) Any individual determined to have been involved in the sale, use, or possession of illegal drugs, while, as applicable, within a protected area of any nuclear power plant, within a facility that is licensed to possess or use SSNM, or within a transporter's facility or vehicle, must be removed from activities within the scope of this part. The individual may not--
(i) Be granted unescorted access to nuclear power plant protected areas;
(ii) Be granted unescorted access to Category IA Material;
(iii) Be given responsibilities to create or have access to safeguards records or procedures for SSNM;
(iv) Be given responsibilities to measure Category IA Material;
(v) Be given responsibilities to transport or escort Category IA Material;
(vi) Be given responsibilities to guard Category IA Material; or
(vii) Be assigned to activities within the scope of this part for a minimum of 5 years from the date of removal.
(4) Persons removed for periods of three years or more under the provisions of paragraphs (b) (2) and (3) of this section for the illegal sale, use or possession of drugs and who would have been removed under the current standards of a hiring licensee, may be granted unescorted access and assigned duties within the scope of this part by a licensee subject to this part only when the hiring licensee receives satisfactory medical assurance that the person has abstained from drugs for at least three years. Satisfactory management and medical assurance of the individual's fitness to adequately perform activities within the scope of this part must be obtained before permitting the individual to perform activities within the scope of this part. Any person granted unescorted access or whose access is reinstated under these provisions must be given unannounced follow-up tests at least once every month for four months and at least once every three months for the next two years and eight months after unescorted access is reinstated to verify continued abstinence from proscribed substances. Any confirmed use of drugs through this process or any other determination of subsequent involvement in the sale, use or possession of illegal substances must result in permanent denial of unescorted access.
(5) Paragraphs (b) (2), (3), and (4) of this section do not apply to alcohol, valid prescriptions, or over-the-counter drugs. Licensee sanctions for confirmed misuse of alcohol, valid prescription, and over-the-counter drugs shall be sufficient to deter abuse of legally obtainable substances as a substitute for abuse of proscribed drugs.
(c) Refusal to provide a specimen for testing and resignation prior to removal for violation of company fitness-for-duty policy concerning drugs must be recorded as removals for cause. These records must be retained for the purpose of meeting the requirements of § 26.27(a).
§ 26.71 Recordkeeping requirements.
Each licensee subject to this part and each contractor and vendor implementing a licensee approved program under the provisions of § 26.23 shall--
(a) Retain records of inquiries conducted in accordance with § 26.27(a), that result in the granting of unescorted access to protected areas, until five years following termination of such access authorizations;
(b) Retain records of confirmed positive test results which are concurred in by the Medical Review Officer, and the related personnel actions for a period of at least five years;
