Current through August 31, 2023
Plans and specifications for municipal wastewater treatment or
				disposal facilities must comply with the facility and design standards set
				forth in Sections 410 through
				599. If design issues are not
				addressed by the facility and design standards, then guidance documents, some
				of which are listed in Section
				008, shall be used as guidance in
				the design and review of plans and specifications for municipal wastewater
				treatment or disposal facilities. See also Section
				007. (3-31-22)
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
			 400.03. The documentation must
			 show the financial arrangements adequate to demonstrate the ability for
			 construction and operation and maintenance of the system according to these
			 rules. Documentation shall also include the name of the wastewater system; the
			 name, address, and phone number of the wastewater treatment facility; and the
			 name, address, and phone number of the responsible charge operator.

02.
Connection to
			 Existing System
. If the proposed project is to be connected to an
			 existing wastewater system, a letter from the existing system must be submitted
			 to the Department stating that the existing system will be able to provide
			 services to the proposed project. The Department may require further
			 documentation showing the ability of the existing system to provide service to
			 the new system. This letter must be submitted prior to or concurrent with the
			 submittal of plans and specifications as required in Subsection
			 400.03. (3-31-22)

Plan and Specification
			 Review
. (3-31-22)
a. Except as provided
			 in Subsection 400.03.b., all plans and
			 specifications for the construction of new sewage systems, sewage treatment
			 plants or systems, other municipal wastewater treatment or disposal facilities,
			 or for material modifications to existing sewage treatment plants or systems,
			 municipal wastewater treatment or disposal facilities shall be submitted to the
			 Department for review and approval before construction may begin and all
			 construction shall be in substantial compliance therewith. This does not
			 include plan and specifications for facilities for sludge disposal, but does
			 include plans and specifications for treatment or storage of sludge. If
			 construction does not commence within twelve (12) months of the Department's
			 final approval of plans and specifications, the Department may require
			 resubmittal of all or part of the plans and specifications for review. The
			 Department shall review plans and specifications and endeavor to resolve design
			 issues within forty-two (42) calendar days of submittal such that approval can
			 be granted. If the Department and applicant have not resolved design issues
			 within forty-two (42) calendar days or at any time thereafter, the applicant
			 may file a written demand to the Department for a decision. Upon receipt of
			 such written demand, the Department shall deliver a written decision to the
			 applicant within no more than seven (7) calendar days explaining any reasons
			 for disapproval. The Department shall maintain records of all written demands
			 for decision made pursuant to Subsection
			 400.03.a. with such records
			 including the final decision rendered and the timeliness thereof. No material
			 deviation shall be made to the approved plans and specifications without the
			 prior approval of the Department. (3-31-22)
b. Plans developed for simple wastewater main
			 extensions, when such facilities will be owned and operated by a city, county,
			 quasi-municipal corporation or regulated public utility, shall not require
			 preconstruction approval by the Department, provided that such plans and
			 specifications are reviewed and approved by a QLPE to verify compliance with
			 the requirements of these rules prior to initiation of construction. At the
			 discretion of the city, county, quasi-municipal corporation or regulated public
			 utility, the plans addressed by this subsection may be referred to the
			 Department for review and approval prior to initiation of construction. The
			 Department has the authority to review plans and specifications approved by a
			 QLPE and can require modifications if the plans and specifications do not meet
			 facility and design standards. Any plans and specifications approved pursuant
			 to Subsection 400.03.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
			 400.03.b.i. through
			 400.03.b.vii. The plans and specifications must be sealed, signed, and dated by
			 the professional engineer in responsible charge of their preparation, and the
			 approval or transmittal letter must be sealed, signed, and dated by the QLPE
			 that is approving the plans and specifications. (3-31-22)
i. A statement that the author of the
			 transmittal letter is the QLPE representing the city, county, quasimunicipal
			 corporation or regulated public entity. (3-31-22)
ii. A statement that the extension project
			 complies with the current facility plan or preliminary engineering report, or a
			 statement that the sewer system/treatment facility has adequate capacity.
			 (3-31-22)
iii. A statement from the
			 city, county, quasi-municipal corporation or regulated public entity or its
			 authorized agent that the wastewater system owner will serve the project.
			 (3-31-22)
iv. A statement from the
			 city, county, quasi-municipal corporation or regulated public entity or its
			 authorized agent that the wastewater system owner will own and operate the
			 project after construction is complete. (3-31-22)
v. A statement by the QLPE that the plans and
			 specifications are approved for construction. (3-31-22)
vi. A statement by the QLPE that the plans
			 and specifications comply with the facility standards within these rules.
			 (3-31-22)
vii. A statement
			 recommending whether sanitary restrictions can be released or should remain in
			 force. (3-31-22)
c.
			 Subsections 400.03.c.i. through
			 400.03.c.vi. outline the projects which QLPEs may approve and which QLPEs may
			 not approve. (3-31-22)
i. A QLPE may approve
			 plans and specifications for simple wastewater main extensions that will be
			 able to discharge to an existing wastewater 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. (3-31-22)
ii. A QLPE may approve plans for simple
			 wastewater main extensions which will discharge to an existing wastewater
			 system owned by a city, county, quasi-municipal corporation, or regulated
			 public utility, 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. (3-31-22)
iii. A QLPE may not approve plans and
			 specifications which include mechanical systems such as lift stations or
			 treatment works. (3-31-22)

			 QLPE may not approve plans and specifications for projects which the QLPE was
			 the design engineer or otherwise involved in the design. (3-31-22)
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. (3-31-22)
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. (3-31-22)
