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,

(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)

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.
