Section 18 AAC 80.200 - System classification and plan approval(a) The department will classify each public water system as a community water system, non-transient non-community water system, or transient non-community water system, based on information (1) submitted by the owner of the system; and(2) compiled by the department.(b) Subject to (c), (d), (f), and (g) of this section, in order to construct, install, alter, renovate, operate, or improve a community water system, non-transient non-community water system, or transient non-community water system, or any part of one, the owner must have prior written approval of engineering plans that comply with 18 AAC 80.205.(c) Written approval under this section is not required for an emergency repair or routine maintenance of a public water system or for a single-service line installation or modification.(d) The design of a public water system in existence on or before October 1, 1999 and that did not receive plan approval by the department must conform to standard sanitary engineering principles and practices and adequately protect the public health. If the system does not conform to standard sanitary engineering principles and practices, the owner may seek department approval for an alternate design for the system by submitting a report that justifies the alternate design. The report must (1) be signed and sealed by a registered engineer;(2) include considerations of soil type, surface water influence, groundwater, surface topography, geologic conditions, data showing the capability of the water system source to meet minimum water consumption needs, storage capacity, the production capability of the water treatment plant, well logs, well yield test results, and other conditions considered by the department as important in establishing the adequacy of the system to reliably protect public health;(3) include a set of engineering plans of the existing system with an accurate description, including the number and location, of potential sources of contamination, water bodies, water sources in the area, and service connections; and(4) include the name, address, telephone number, and facsimile number of the owner.(e) If a public water system described in (d) does not adequately protect the public health, the department will require the system to be redesigned and approved in accordance with this chapter.(f) If the department approves an alternate design under (d) of this section, the owner shall (1) ensure that the system (A) continues to meet the primary MCLs set by 18 AAC 80.300(b); and(B) meets the secondary MCLs as required in 18 AAC 80.300(c); and(2) in addition to monitoring required for the contaminants for which MCLs are set under 18 AAC 80.300, perform any contaminant monitoring that the department determines necessary to serve the interests of public health.(g) Written approval under this section is not required for a project that is approved to demonstrate an innovative technology or device in a public water system under 18 AAC 80.225, provided the project does not exceed one year from the date of installation to the date that the demonstration ends.Eff. 10/1/99, Register 151; am 3/25/2001, Register 157; am 4/24/2009, Register 190; am 7/25/2010, Register 195; am 2/11/2017, Register 221, April 2017Guidance on standard sanitary engineering principles and practices, as addressed in 18 AAC 80.200(d), may be found in the references listed at 18 AAC 80.010(d).
