Current through Register Vol. 50, No. 6, June 20, 2024
A. [Formerly
				  paragraph A:6.1 of Appendix A] Mechanical wastewater treatment plants are small
				  plants capable of providing primary and secondary treatment of sanitary sewage.
				  All are considered to be aerobic treatment units.
B. [Formerly paragraph A:6.2 of Appendix A]
				  An individual mechanical plant will be permitted where individual sewerage
				  systems would currently be permitted under prevailing rules as set forth in
				  this Part of the state sanitary code. Sewage loading criteria for determining
				  the average daily design flow and organic loading are contained in Chapter 15
				  of this Part.
C. [Formerly
				  paragraph A:6.3 of Appendix A] An individual mechanical plant will be permitted
				  in lieu of a conventional septic tank system (septic tank/absorption field)
				  only in accordance with the provisions of §511. B of this Code, and where a
				  conventional septic tank system could not be permitted.
D. [Formerly paragraph A:6.4 of Appendix A]
				  Permitted individual mechanical plants shall strictly comply with National
				  Sanitation Foundation International Standard, NSF 40-1996 for Residential
				  Wastewater Treatment Systems (Class I Systems) as revised May 1996 and
				  published by NSF International, P.O. Box 130140, Ann Arbor, Michigan 48113-0140
				  USA, and as has been approved by the American National Standards Institute, 11
				  West 42nd Street, New York, New York 10036 as standard ANSI/NSF 40-1996,
				  revised May 28, 1996.
E. [Formerly
				  paragraph A:6.5 of Appendix A] All individual mechanical plants currently
				  approved for installation in Louisiana as of the effective date of these
				  regulations shall not be required to meet the requirements of §725. D until
				  March 1, 2001. Until March 1, 2001, plants shall continue to comply with the
				  standards under which they were approved. Effective March 1, 2001, all plants
				  shall comply with the standard as stated in §725 D
F. [Formerly paragraph A:6.6 of Appendix A]
				  In addition to evidence of strict compliance with NSF International Standard
				  NSF 40-1996 (Class I Systems), and ANSI/NSF 40-1996 (Class I Systems), as are
				  specified in §725. D of this Code, the following Department of Health and
				  Hospitals/Office of Public Health (DHH/OPH) requirements shall also apply.
1. Testing/Evaluation (General)
a. All certifications of individual
				  mechanical plants shall be conducted by an American National Standards
				  Institute (ANSI) accredited certification program testing/evaluation facility
				  authorized for such purpose(s). Verification of such certification shall be
				  provided to DHH/OPH, subject to acceptance by DHH/OPH of such verification, as
				  prerequisite to consideration of any individual mechanical (residential) plant
				  for permitting in Louisiana.
b.
				  Evidence of acceptance by DHH/OPH of an ANSI accredited testing/evaluation
				  facility, for purpose of testing/evaluation of individual mechanical
				  (residential) plant(s) for permitting in Louisiana shall be demonstrated upon
				  execution of an appropriate Memorandum of Understanding (MOU), or other,
				  similar contractual instrument, subject to terms and conditions as may be
				  imposed by DHH/OPH-said MOU to be between DHH/OPH and the testing/evaluation
				  facility.
c. Successful completion
				  of testing/evaluation of an individual mechanical (residential) plant in
				  accordance with applicable provisions of this Code, having been properly
				  tested/evaluated and certified by an appropriate facility, shall serve to allow
				  the DHH/OPH authorization of an individual mechanical (residential) plant for
				  permitting purposes in Louisiana for a period not to exceed seven years from
				  the date of such DHH/OPH authorization, or until such time as an appropriate
				  revision to the prevailing testing/evaluation standard for such purposes may
				  become revised. Such authorization of an individual mechanical (residential)
				  plant for permitting purposes in Louisiana shall be in the form of a written
				  license by DHH/OPH to a manufacturer of such individual mechanical
				  (residential) plant(s), subject to compliance with applicable provisions of
				  this Code-such license to be valid for the specified period, annually
				  renewable, and suspendable/revocable by DHH/OPH in accordance with license
				  revocation procedures as specified in §735 F
