15.06.080 POU and POE Operations and Maintenance (O&M) Program for Water Systems.
A. Prior to installing a POU or POE treatment device, a water system shall submit a POU/POE Operations and Maintenance (O&M) Program for Director review and shall obtain Director approval of the Program. The POU/POE O&M Program shall include, but not be limited to, the following:
1. An installation protocol that, at a minimum, describes locations and assurances that the POU or POE treatment devices will be accessible for operation and maintenance;
2. The type and frequency of maintenance, at intervals specified by the manufacturer and determined by pilot testing, whichever is shorter, that ensures the POU or POE treatment device produces effluent that meets primary water quality standards;
3. A list of replacement parts for the POU or POE treatment device;
4. Replacement schedules for critical components;
5. The qualifications and identification of the person(s) responsible for the POU or POE treatment device installation, operation, and maintenance; and
6. POU or POE treatment device waste-handling and disposal procedures.
B. A protocol for how the water system shall ensure that the POU or POE treatment device is functioning properly at least every twelve (12) months.
C. Based on the ongoing operation and maintenance of installed POU or POE treatment devices, a water system shall revise its POU or POE O&M Program as necessary to ensure continuous effective treatment and to ensure that systems produce effluent that meets primary water quality standards. The Revised POU or POE O&M Program shall be submitted to the Director for review and approval prior to implementation of the revised Program.
D. A water system shall maintain a copy of and implement its most recent POU/POE O&M Program prepared and approved pursuant to this Section.

15.06.090 POU and POE Monitoring Program for Water Systems.
A. A water system shall submit a POU/POE Monitoring Program to the Director for review and shall obtain Director approval of the Monitoring Program. The samples shall be analyzed by a laboratory as defined by Monterey County Code Section 15.06.020(l). At a minimum, the POU/POE Monitoring Program shall include monitoring of the contaminant(s) for which the water system has applied to use the POU or POE treatment device, as follows:
1. Initial POU/POE effluent, with samples collected as soon as possible but no later than seventy-two (72) hours after a device is installed;
2. Annual POU/POE effluent, following the monitoring in Subsection (A)(1) with one quarter (1/4) of all units sampled quarterly on a rotating basis; and
3. Quarterly source water monitoring, with samples collected during the same month (first, second, or third) of each calendar quarter. After one year of monitoring, a water system may apply to the Director for reduced ongoing monitoring if current and historical results do not indicate an upward trend in contaminant levels.
B. The Director may require further monitoring for the contaminant of concern or other contaminants, including microbial contaminants, based on monitoring results, the health risk associated with the contaminant, POU/POE technology, or a water system’s compliance with this Chapter.
C. The water system shall revise its POU/POE Monitoring Program as necessary based on the ongoing operation and maintenance of installed POU or POE treatment systems or additional monitoring required pursuant to Subsection (B) of this Section. The Revised POU/POE Monitoring Program shall be submitted to the Director for review and approval prior to implementation of the revised Program.
D. The water system shall maintain a copy of and implement its most recent POU/POE Monitoring Program prepared and approved pursuant to this Section.
E. If an ongoing POU/POE effluent sample result exceeds any primary water quality standard, the water system shall take all of the following actions:
1. Implement the public notification and alternative water procedures identified in its Director-approved POU/POE Treatment Strategy.
2. Except as noted in Subsection (E)(3) below, collect a confirmation sample within seven (7) days of notification of the exceedance.
3. For an exceedance of a nitrate, nitrite, nitrate plus nitrite, or perchlorate Maximum Contaminant Level (MCL):
a. As soon as possible, but no later than twenty-four (24) hours following notification of an exceedance, provide each affected consumer with notification; and
b. Collect a confirmation sample within seventy-two (72) hours of notification of the exceedance.
4. If the confirmation sample or the average of the original and confirmation sample exceeds the MCL, notify the Director within twenty-four (24) hours of the result, complete corrective actions as soon as possible but within one (1) month of receipt of the result, and increase the monitoring frequency if requested to do so by the Director.
