(a) The following general requirements apply to all monitoring required by this Subpart or the permit:

1. (1) Samples and measurements taken for the purpose of monitoring must be representative of the activity and medium being monitored.
2. (2) The monitoring systems and data evaluation process must have sufficient sensitivity to demonstrate that the performance objectives and all applicable Federal and State environmental standards are met.
3. (3) The permittee must maintain monitoring systems and equipment in good working order and protect them from tampering, vandalism, and inclement weather.
4. (4) All monitoring systems and equipment must be periodically inspected, tested, and calibrated to ensure the proper and continuous functioning of the monitoring system and equipment.
5. (5) All monitoring programs must include collection of data to be used as input to the models used in the technical analysis required by sections 383-3.4(h)(2) and 383-13.4(b)(8) of this Part.
6. (6) If a monitoring station required by this Part fails to operate properly or is unexpectedly removed from service, the permittee must immediately notify the department. Unless otherwise directed by the department, the permittee must replace or repair the monitoring station, as necessary, to bring the station back into operation as soon as possible.
7. (7) A systematic numbering system must be established for all samples collected, and a unique identification number must be assigned to each sample.

8. (8) The permittee must retain and maintain records of all monitoring information, including all calibration and maintenance records and all original strip chart recordings for continuous monitoring instrumentation in accordance with section 383-13.2 of this Part. Records of monitoring information must include:

   1. (i) the date, exact place, sample identification number, and time of sampling or measurements;
   2. (ii) the name of the individual who performed the sampling and measurements;
   3. (iii) the date the analyses were performed;
   4. (iv) the name of the individual who performed the analyses;
   5. (v) the analytical techniques or methods used;
   6. (vi) the result of such analyses with radiological results reported in both the International System of Units (i.e., becquerels, grays, and sieverts) and customary units (i.e., curies, rads, and rems);
   7. (vii) records of internal laboratory quality assurance and control; and
   8. (viii) additional information relating to the analyses as requested by the department.
9. (9) Monitoring data in the permittee's computer must at all reasonable times be available to the department through electronic access to the permittee's computer. Where continuous monitoring data are transmitted by telephone from the monitoring device to the permittee's computer, the permittee must provide to the department telephone access to the data at all times.
10. (10) When facility closure is commenced, a closure, post-closure and institutional control period environmental monitoring program must be implemented. This monitoring program must be based on the disposal method(s), the site design, the operating history and the closure and stabilization of the disposal site. It must be approved by the department in the modification of the permit for facility closure.
11. (11) Monitoring during the closure, post-closure, and institutional control periods must, to the maximum extent practicable, utilize the same monitoring points as those that were utilized during the operation of the land disposal facility.

12. (12) Monitoring plans submitted by the applicant must include a description of the following:

    1. (i) the media to be monitored;
    2. (ii) the equipment, instruments, and facilities to be used;
    3. (iii) the data recording and statistical analysis procedures to be used;
    4. (iv) the organization of the staff that will perform the monitoring; and

    5. (v) the quality assurance and quality control procedures to be followed.

       (b) General inspection requirements.

13. (1) The owner or operator must inspect the land disposal facility for malfunctions and deterioration, operator errors, and discharges that may be causing or may lead to:

    1. (i) release of radioactive material to the environment; and
    2. (ii) a threat to public health and safety. The owner or operator must conduct these inspections often enough to identify problems in time to correct them before they harm public health and safety or the environment.

14. (2) The owner or operator must develop and follow a written schedule for inspecting monitoring equipment, safety and emergency equipment, security devices, and operating and structural equipment that are important to preventing, detecting, or responding to environmental or public health hazards.

    1. (i) The operator must keep this schedule at the land disposal facility.
    2. (ii) The schedule must identify the types of problems (e.g.,malfunctions or deterioration) which are to be looked for during the inspection.
    3. (iii) The frequency of inspection may vary for the items on the schedule. However, it should be based on the rate of possible deterioration of the equipment and the probability of an environmental or public health and safety incident if the deterioration or malfunction or any operator error goes undetected between inspections.
15. (3) The owner or operator must remedy any deterioration or malfunction of equipment or structures found during the inspection on a schedule which ensures that the problem does not lead to an environmental or public health and safety hazard. Where a hazard is imminent or has already occurred, action to remedy the problem must be taken immediately.
16. (4) The owner or operator must record inspections in an inspection log or summary, and must retain those records as required by section 383-13.2 of this Part. At a minimum these records must include the date and time of the inspection the name of the inspector, a notation of the observations made, and the date and nature of any repairs or other actions taken to remedy problems found.
