Idaho Administrative Code › Title IDAPA 58 - Environmental Quality, Department of › Rule 58.01.08 - IDAHO RULES FOR PUBLIC DRINKING WATER SYSTEMS › Section 58.01.08.504 - FACILITY AND DESIGN STANDARDS: REVIEW OF PLANS AND SPECIFICATIONS

Current through August 31, 2023
The facility and design standards set forth in these rules
				shall be applied in the review of plans and specifications for public water
				system facilities. If design issues are not addressed by the facility and
				design standards set out in these rules, then guidance documents, some of which
				are listed in Subsection
				002.02, shall be used as
				guidance in the design and review of plans and specifications for public
				drinking water facilities. See also Section
				013. (3-24-22)
01.
Ownership
. Documentation of
			 the ownership and responsibility for operating the proposed system shall be
			 made available to the Department prior to or concurrent with the submittal of
			 plans and specifications as required in Subsection
			 504.03. The documentation must
			 show organization and financial arrangements adequate to assure construction,
			 operation and maintenance of the system according to these rules. Documentation
			 shall also include the name of the water system, the name, address, and phone
			 number of the supplier of water, the system size, and the name, address, and
			 phone number of the system operator. (3-24-22)
02.
Connection to an Existing
			 System
. If the proposed project is to be connected to an existing public
			 water system, a letter from the purveyor must be submitted to the Department
			 stating that the purveyor will be able to provide services to the proposed
			 project. The Department may require documentation supporting the ability of the
			 purveyor to provide service to the new system without diminishing quality of
			 service to existing customers. This letter must be submitted prior to or
			 concurrent with the submittal of plans and specifications as required in
			 Subsection 504.03. (3-24-22)
03.
Plans and Specifications
			 Required
. (3-24-22)
a. Prior to
			 construction of new public drinking water systems, new drinking water systems
			 designed to serve fifteen (15) or more service connections, or material
			 modifications of existing public water systems, plans and specifications must
			 be submitted to the Department for review and approval. Construction should
			 commence as soon as practical after approval, and if construction is not
			 completed within twelve (12) months of the Department's final approval, an
			 extension or re-approval must be obtained from the Department. The Department
			 may require resubmittal of all or part of the plans and specifications prior to
			 issuing an extension or re-approving the plans and specifications.
			 (3-24-22)
b. Plans and
			 specifications for simple water main extensions shall not require
			 pre-construction approval by the Department when such extensions will be owned
			 and operated by a city, county, quasi-municipal corporation or regulated public
			 utility, provided that such plans and specifications are reviewed and approved
			 by a QLPE who was not involved in the preparation of the plans and
			 specifications being reviewed to verify compliance with the requirements of
			 these rules prior to initiation of construction. Any plans and specifications
			 approved pursuant to Subsection
			 504.03.b. shall be transmitted
			 to the Department at the time construction is authorized and shall be marked or
			 stamped as "Approved for Construction." Along with the plans and
			 specifications, the transmittal must include the items listed in Subsections
			 504.03.b.i. through
			 504.03.b.vii. The plans and specifications must bear the imprint of an Idaho
			 licensed professional engineer's seal that is both signed and dated by the
			 engineer, and the approval or transmittal letter must be sealed, signed, and
			 dated by the QLPE that is approving the plans and specifications. (3-24-22)
i. A statement that the author of the
			 transmittal letter is the QLPE representing the city, county, quasi-municipal
			 corporation or regulated public entity. (3-24-22)
ii. A statement that the extension project
			 complies with the current facility plan or preliminary engineering report, or a
			 statement that the water system has adequate capacity. Please see Subsection
			 502.01.b. for further
			 information. (3-24-22)
iii. A
			 statement from the city, county, quasi-municipal corporation or regulated
			 public entity or its authorized agent that the water system purveyor will serve
			 the project. (3-24-22)
iv. A
			 statement from the city, county, quasi-municipal corporation or regulated
			 public entity or its authorized agent that the water system purveyor will own
			 and operate the project after construction is complete. (3-24-22)
v. A statement by the QLPE that the plans and
			 specifications are approved for construction. (3-24-22)
vi. A statement by the QLPE that the plans
			 and specifications comply with the facility standards within these rules.
			 (3-24-22)
vii. A statement
			 recommending whether sanitary restrictions can be released or should remain in
			 force. (3-24-22)
c.
			 Subsections 504.03.c.i. through
			 504.03.c.vi. outline the projects which QLPEs may approve and which QLPEs may
			 not approve. (3-24-22)
i. A QLPE may approve
			 plans and specifications for simple water main extensions that are able to
			 connect to an existing water system owned by a city, county, quasi-municipal
			 corporation, or regulated public utility at the time the extension is approved
			 for construction by the QLPE. (3-24-22)
ii. A QLPE may approve plans for simple water
			 main extensions which will connect to an existing water system, but are unable
			 to connect to the system at the time the extension is approved for construction
			 by the QLPE, provided sanitary restrictions remain in force for the proposed
			 extension. (3-24-22)
iii. A QLPE
			 may not approve plans and specifications which include mechanical systems such
			 as booster stations. (3-24-22)
iv.
			 A QLPE may not approve plans and specifications for projects which the QLPE was
			 the design engineer or otherwise involved in the design. (3-24-22)
v. A QLPE employed by a city, county,
			 quasi-municipal corporation, or regulated public utility may approve a design
			 that was prepared by a subordinate engineer or an engineer from a separate
			 design group within the city, county, quasi-municipal corporation, or regulated
			 public utility. (3-24-22)
vi. A
			 QLPE who is not employed by a city, county, quasi-municipal corporation, or
			 regulated public utility, but is retained by a city, county, quasi-municipal
			 corporation, or regulated public utility for the purpose of plan and
			 specification review may not approve projects designed by the company with
			 which the QLPE is employed. (3-24-22)
d. At the discretion of the city, county,
			 quasi-municipal corporation or regulated public utility, the plans addressed by
			 Subsection 504.03.b. may be referred to the
			 Department for review and approval prior to initiation of construction.
