Oregon Administrative Rules › Chapter 333 - OREGON HEALTH AUTHORITY, PUBLIC HEALTH DIVISION › Division 61 - DRINKING WATER › Section 333-061-0060 - Plan Submission and Review Requirements

Current through Register Vol. 63, No. 7, July 1, 2024
(1) Plan Submission:
(a) Construction and installation plans shall
			 be submitted to and approved by the Authority before construction begins on new
			 systems or major additions or modifications, as determined by the Authority,
			 are made to existing systems. Corrosion control studies conducted according to
			 OAR 333-061-0034(3)(b)  must be submitted to and approved by the Authority prior
			 to installation of treatment. Plans shall be drawn to scale;
(b) Preliminary plans, pilot studies, master
			 plans and construction plans shall be prepared by a Professional Engineer
			 registered in Oregon, and submitted to the Authority unless exempted by the
			 Authority (See OAR 333-061-0060(4));
(c) Plans shall set forth the following:
(A) Sufficient detail, including
			 specifications, to completely and clearly illustrate what is to be constructed
			 and how those facilities will meet the construction standards set forth in
			 these regulations. Elevation or section views shall be provided where required
			 for clarity;
(B) Supporting
			 information attesting to the quality of the proposed source of water;
(C) Vicinity map of the proposed project
			 relative to the existing system or established landmarks of the area;
(D) Name of the owner of the water system
			 facilities during construction and the name of the owner and operator of the
			 facilities after completion of the project;
(E) Procedures for cleaning and disinfecting
			 those facilities which will be in contact with the potable water.
(d) Prior to drilling a well, a
			 site plan shall be submitted which shows the site location, topography,
			 drainage, surface water sources, specifications for well drilling, location of
			 the well relative to sanitary hazards, dimensions of the area reserved to be
			 kept free of potential sources of contamination, evidence of ownership or
			 control of the reserve area and the anticipated depth of the aquifer from which
			 the water is to be derived. The Authority will review well reports from the
			 area and in consultation with the local watermaster and the well constructor as
			 appropriate will recommend the depth of placement of the casing seal. After the
			 well is drilled, the following documents shall be submitted to the Authority
			 for review and approval: Well driller's report, report of the pump test which
			 indicates that the well has been pumped for a sufficient length of time to
			 establish the reliable yield of the well on a sustained basis, including data
			 on the static water level, the pumping rate(s), the changes in drawdown over
			 the duration of the test, the rate of recovery after the pump was turned off,
			 reports on physical, chemical and microbiological quality of the well water,
			 performance data on the well pump, a plan of the structure for protecting
			 above-ground controls and appurtenances, and a plan showing how the well will
			 be connected to the water system. (See OAR 333-061-0050(2)).
(e) Any community, NTNC, or TNC that treats
			 surface water or groundwater under the influence of surface water and that
			 desires to make a significant change to its disinfection treatment process as
			 defined by paragraphs (1)(e)(A) through (1)(e)(D) of this rule, is required to
			 develop a disinfection profile and calculate a disinfection benchmark according
			 to OAR 333-061-0036(4)(e). The water system must consult with and provide any
			 additional information requested by the Authority prior to making such a
			 change. The water system must develop a disinfection profile for
Giardia lamblia
and viruses, calculate a disinfection
			 benchmark, describe the proposed change in the disinfection process, and
			 analyze the effect(s) of the proposed change on current levels of disinfection
			 according to the USEPA Disinfection Profiling and Benchmarking Guidance Manual
			 or the USEPA LT1-ESWTR Disinfection Profiling and Benchmarking Technical
			 Guidance Manual and submit the information to the Authority for review and
			 approval. Significant changes to the disinfection treatment process include:
(A) Changes to the point of
			 application:
(B) Changes to the
			 disinfectants used in the treatment process;
(C) Changes to the disinfection
			 process;
(D) Any other modification
			 identified by the Authority.
(f) A water system that uses either
			 chloramines, chlorine dioxide, or ozone for primary disinfection, and that is
			 required to prepare a disinfection profile for
Giardia lamblia
as prescribed by subsection (1)(e) of this rule, must also prepare a
			 disinfection profile for viruses and calculate the logs of inactivation for
			 viruses using the methods specified in OAR 333-061-0036(4)(l).
