(1) Except as provided by subsection (2) of this section, all plans and specifications for the construction of new sewage systems, sewage treatment plants or systems, other waste treatment or disposal facilities, public water supply systems or public water treatment systems or for material modification or expansion to existing sewage treatment plants or systems, waste treatment or disposal facilities, public water supply systems or public water treatment systems, shall be submitted to and approved by the director before construction may begin, and all construction shall be in substantial compliance therewith. Material modifications are those that are intended to increase system capacity or to alter the methods or processes employed. The director shall review plans and specifications and endeavor to resolve design issues within forty-two (42) days of submittal such that approval can be granted. If the director and applicant have not resolved design issues within forty-two (42) days or at any time thereafter, the applicant may file a written demand to the director for a decision. Upon receipt of such written demand, the director shall deliver a written decision to the applicant within no more than seven (7) days explaining any reasons for disapproval. The director shall maintain records of all written demands for decision made pursuant to this subsection with such records including the final decision rendered and the timeliness thereof. No material deviation shall be made from the approved plans and specifications without the prior approval of the director.
(2) Plans meeting the following standards shall not require preconstruction approval by the director:
(a) Plans for dairy systems pursuant to section 37-401, Idaho Code.
(b) Plans developed to evidence compliance with storm water best management practices.
(c) Plans developed for routine maintenance or equipment replacement activities.
(d) Plans for sanitary sewer extensions, water main extensions, and storm drain extensions, when such facilities will be owned and operated by a city, county, quasi-municipal corporation or regulated public utility where such city, county, quasi-municipal corporation or regulated public utility provides for the review of such plans and specifications by a qualified licensed professional engineer to verify compliance with facility standards and approves construction plans prior to initiation of construction. Any plans approved pursuant to this subsection shall be transmitted to the director at the time construction is authorized along with a statement that the plans comply with the facility standards and that construction has been authorized by the public agency or public utility. At the discretion of any city, county, quasi-municipal corporation or regulated public utility, the plans addressed by this subsection may be referred to the director for review and approval prior to initiation of construction.
(3) Within thirty (30) days of the completion of construction of facilities for which plans are required to be reviewed pursuant to subsection (1) or subsection (2)(d) of this section, record plans and specifications based on information provided by the construction contractor and field observations made by the engineer or the engineer’s designee depicting the actual construction of facilities performed must be submitted to the director by the engineer representing the public agency or regulated public utility, if the resultant facilities will be owned and operated by a public agency or regulated public utility, or by the design engineer or owner-designated substitute engineer if the constructed facilities will not be owned and operated by a public agency or regulated public utility. Such submittal by the professional engineer must confirm material compliance with the approved plans or disclose any material deviations therefrom. If construction does not materially deviate from the original plans and specifications previously provided to the department, the owner may have a statement to that effect prepared by a licensed professional engineer and filed with the department in lieu of submitting a complete and accurate set of record drawings.
(4) All plans and specifications submitted to satisfy the requirements of subsection (1) of this section and all plans approved pursuant to subsection (2)(d) of this section shall be in compliance with applicable facility and design standards and conform in style and quality to regularly accepted engineering standards. The department shall review plans to determine compliance with applicable facility standards and engineering standards of care. As long as the plans and specifications comply with applicable facility and design standards, the department shall not substitute its judgment for that of the owner’s design engineer concerning the manner of compliance with design standards. Except with respect to plans and specifications for facilities addressed in subsection (5) of this section, and confined animal feeding operations, the board may require that certain types of plans and specifications must be stamped by registered professional engineers. If the director determines that any particular facility or category of facilities will produce no significant impact on the environment or on the public health, the director shall be authorized to waive the submittal or approval requirement for that facility or category of facilities.
(5) All plans and specifications for the construction, modification, expansion, or alteration of waste treatment or disposal facilities for aquaculture facilities licensed by the department of agriculture for both commercial fish propagation facilities as defined in section 22-4601, Idaho Code, and sport fish propagation facilities whether private or operated or licensed by the department of fish and game and other aquaculture facilities as defined in the Idaho waste management guidelines for aquaculture operations, shall be submitted to and approved by the director of the department of environmental quality before construction may begin and all construction shall be in compliance therewith. The director shall review plans and specifications within forty-five (45) days of submittal and notify the owner or responsible party of approval or disapproval. In the event of disapproval the director shall provide reasons for disapproval in writing to the owner or responsible party. Plans and specifications shall conform in style and quality to standard industry practices and guidelines developed pursuant to this subsection. The director shall establish industry guidelines or best management practices subcommittees composed of members of the department, specific regulatory agencies for the industry, general public, and persons involved in the industry to develop and update guidelines or best management practices as needed. Within thirty (30) days of the completion of the construction, modification, expansion or alteration of facilities subject to this subsection, the owner or responsible party shall submit a statement to the director that the construction has been completed and is in substantial compliance with the plans and specifications as submitted and approved. The director shall conduct an inspection within sixty (60) days of the date of submission of the statement and shall inform the owner or responsible party of its approval of the construction or in the event of nonapproval, the reasons for nonapproval.
