Section 58.01.08.302 - SANITARY SURVEYSThe Department conduct a sanitary survey of all PWSs. Sanitary surveys will include, but are not limited to, the following elements: source; treatment; distribution system; finished water storage; pump, pump facilities, and controls; monitoring and reporting and data verification; PWS management and operation; and operator compliance with state requirements. For those PWSs using groundwater, 40 CFR Part 141, Subpart S, is incorporated by reference.
01.Frequency. For non-community PWSs, a sanitary survey must be conducted every five (5) years. For community PWSs, a sanitary survey will be conducted every three (3) years, except as provided below. a. Community systems using surface water or groundwater under the direct influence of surface water that have been determined to have outstanding performance, according to criteria established by the Department, may have a sanitary survey conducted every five (5) years.b. Community systems using groundwater may have a sanitary survey conducted every five (5) years if the PWS provides at least a four (4)-log treatment of viruses (using inactivation, removal, or a Department-approved combination of 4-log inactivation and removal) before or at the first customer for all of its groundwater sources.c. Community systems using groundwater may have a sanitary survey conducted every five (5) years if they have an outstanding performance record, as determined by the Department and documented in previous sanitary surveys, and have no history of Revised Total Coliform Rule MCL or monitoring violations under Subsection 100.01 since the last sanitary survey.02.Report. The Department will provided a report describing the results of the sanitary survey to the PWS. As part of the sanitary survey report or as an independent action, the Department will provide written notice to the PWS describing any significant deficiency within thirty (30) days after the Department identifies the significant deficiency. The notice may specify corrective actions and deadlines for completion of corrective actions.03.Significant Deficiencies. For each of the eight (8) elements of a sanitary survey of a groundwater system, the Department will consider the following deficiencies significant in all cases for the purposes of the notice required in Subsection 303.02.

Distribution system: A minimum system pressure of twenty (20) psi is not maintained throughout the distribution system as specified in Subsection 552.01.b.d. Finished water storage: Roof leaking, as specified in Subsections 544.09 and 544.09.c.e. Pumps, pump facilities, and controls: A pump house must be protected from contamination and unauthorized entry, as specified in Subsection 541.01.f. Monitoring, reporting, and data verification: Repeated failure to collect the required number and type of Revised Total Coliform Rule samples during the most recent two (2) year period, as specified in Subsection 100.01.g. PWS management and operation: History of frequent depressurization in the distribution system in violation of Subsection 552.01.h. Operator compliance with state licensing requirements: The PWS does not have a properly licensed responsible charge operator as required in Subsection 554.02.04.Response Required. After notification from the Department of significant deficiencies, the owner of a PWS must respond in writing, describing how and on what schedule the PWS will address all significant deficiencies, not later than forty-five (45) days for PWSs using surface water or groundwater under the direct influence of surface water or thirty (30) days for PWSs only using groundwater.05.Consultation with the Department. PWS owners must consult with the Department prior to taking specific corrective actions in response to significant deficiencies identified during a sanitary survey, unless such corrective actions are specified in detail by the Department in its written notification under Subsection 302.02.06.Violation.
