  (1) Definition.

  A public drinking water project is any of the following:

  (a) Construction of, addition to, or modification of a public drinking water facility that may affect the quality or quantity of water delivered.

  (b) Any activity that may affect the quality or quantity of water delivered by an existing public drinking water system including:

  (i) the interior re-coating or re-lining of any raw or drinking water storage tank, or water storage chamber within any treatment facility,

  (ii) the in-situ re-lining of any pipeline,

  (iii) a change or addition of a water treatment process,

  (iv) the re-development of any spring or well source,

  (v) replacement of a well pump with one of different capacity,

  (vi) deepening a well,

  (vii) well rehabilitation or cleaning using a chemical other than a disinfectant previously approved for drinking water use, and

  (viii) replacement of pipeline not due to on-going operation and maintenance.

  (2) On-going Operation and Maintenance Procedures.

  On-going operation and maintenance procedures are not considered public drinking water projects and, accordingly, are not subject to the project notification, plan approval and operating permit requirements of this rule. However, these activities shall be carried out in accordance with all requirements contained in R309-500 through R309-550 and specifically the design, construction, disinfection, flushing, and bacteriological sampling and testing requirements before the facilities are placed back into service. The following activities are considered to be on-going operation and maintenance procedures:

  (a) pipeline leak repair,

  (b) replacement of deteriorated pipeline where the new pipeline segment is the same size as the old pipeline or the new segment is upgraded to meet the minimum pipeline sizes required by R309-550-5(4) or larger sizes as determined by a hydraulic analysis in accordance with R309-550-5(3),

  (c) tapping existing water mains with corporation stops to make connection to new service laterals to individual structures,

  (d) distribution pipeline additions where the pipeline size is the same as the main supplying the addition or the pipeline addition meets the minimum pipeline sizes required by R309-550-5(4) or larger sizes as determined by a hydraulic analysis in accordance with R309-550-5(3), the length is less than 500 feet, and contiguous segments of new pipe total less than 1000 feet in any fiscal year,

  (e) entry into a drinking water storage facility for the purposes of inspection, cleaning and maintenance,

  (f) replacement of equipment or pipeline appurtenances with the same type, size and rated capacity (fire hydrants, valves, pressure regulators, meters, service laterals, chemical feeders and booster pumps including deep well pumps), and

  (g) mechanical well rehabilitation or cleaning using a disinfectant previously approved for drinking water use.
