Current through June 25, 2024
A. Noncompliance
				  Lists
The Executive Director shall prepare and submit to the
					 Regional Administrator (or his/her designee) any lists of facilities in
					 noncompliance as defined and required in
					 40 CFR
					 123.45.
B. Plans and Specifications: Submittal
				  Requirements
(1) Plans and specifications for
				  all proposed municipal and domestic sewage collection systems, including
				  modifications and additions thereto, must be submitted to and approved by the
				  Department prior to beginning construction of the proposed system. With the
				  concurrence of the Department, small privately owned domestic collection
				  systems (less than 1,500 gpd) may be allowed to submit plans and specifications
				  prepared by a licensed plumber or architect.
(2) Except as excluded in Rule 1.1.6.B.5,
				  plans and specifications for all proposed treatment works must be submitted to
				  the Department for comment prior to beginning construction of the proposed
				  works. In addition, plans and specifications for all proposed treatment works
				  for which a Department administered grant or loan has been made or is to be
				  requested must be approved by the Department prior to commencement of
				  construction.
(3) The Department
				  may exempt domestic wastewater facilities with discharges less than 1,500 gpd.
				  Commercial and institutional establishments installing treatment works which
(a) have a design capacity of 1,500 gallons
				  per day or less, and
(b) do not and
				  will not involve a Department administered grant or loan, and
(c) do not require a UIC permit, will
				  normally not be required to submit plans and specifications for the treatment
				  works to the Department.
However, prior to beginning construction, it is required
					 that the Department be advised in writing, of the type and capacity of the
					 system to be constructed, and also the location of the discharge point if
					 applicable.
(4)
				  The Department's receipt, comment, or approval of any document does not relieve
				  the project's owner, consulting engineer, contractor, equipment supplier,
				  attorney, or any other party of any liabilities or responsibilities. Department
				  approval of or comment on any document does not establish or convey any
				  liability or responsibility to the Department, nor does such represent any
				  assurances that the project will be able to comply with any permit requirements
				  or otherwise perform as intended by the owner, consulting engineer, contractor,
				  equipment supplier, attorney, or other parties. The permittee is responsible
				  for complying with all conditions of a permit and ensuring that all
				  construction, operation, and maintenance activities achieve such
				  compliance.
(5) All equipment,
				  structures, facilities, and/or systems installed in accordance with B.1., 2. or
				  6. of this Rule shall be maintained and operated in accordance with A.18 of
				  this Rule.
(6) Except as excluded
				  in 1.1.6.B.5. of this Rule, not later than 60 days after completion of the
				  project, the owner must, through a letter signed by a professional engineer,
				  certify to the Department that the project has been constructed in accordance
				  with final submitted plans and specifications. Where significant changes to the
				  plans and specification have been made, the professional engineer must submit a
				  list of changes with the certification letter. In addition, as built plans and
				  specifications for all municipal and domestic treatment works, and sewage
				  collection systems, must be submitted to the Department not later than sixty
				  (60) days after completion of the project.
(7) All plans and specifications submitted to
				  the Department must be developed by a professional engineer who holds a valid
				  certificate of registration as a professional engineer issued by the
				  Mississippi State Board of Registration for Professional Engineers and Land
				  Surveyors.
(8) The only permits
				  issued by the Permit Board for wastewater discharges are State permits, UIC
				  permits, and NPDES permits. Review and approval of design plans and
				  specifications does not constitute authorization to begin construction, and any
				  permit applicant who commences construction prior to final Permit Board action
				  under Rule 1.1.3.H. builds at his own risk.
(9) Plans and specifications shall be
				  developed utilizing fundamental engineering principles and approved engineering
				  practices from acceptable engineering guidance sources including, but not
				  limited to, Recommended Standards for Sewage Works, ("Ten States Standards" and
				  all amendments), text books, manuals of practice, technical publications, or
				  other appropriate publications.
(10) Plans and specifications that vary from
				  these engineering sources may be submitted if the Department determines such
				  plans and specifications are properly supported in writing by the consulting
				  engineer. A copy of all plans and specifications shall be maintained by the
				  permittee, owner, or operator, whichever is responsible for operation and
				  maintenance of the constructed facilities.
(11) Any proposed significant changes to
				  approved or submitted plans and specifications must be submitted to the
				  Department for approval or comment in accordance with 1.1.6.B.1. or 2 of this
				  Rule. Approval of or comment on such revised plans and specifications may be
				  secured from the Department either before or after construction is initiated,
				  at the discretion of the owner. If the owner constructs such changes reflected
				  on the plans and specifications prior to securing Department approval or
				  comment, the owner does so at his own risk and may be required by the
				  Department to correct any unacceptable changes and/or deficiencies.
