N.J. Admin. Code § 7:9A-8.3 - Advanced wastewater pretreatment components
(a) The use of an
advanced wastewater pretreatment device in addition to a septic tank, or in
lieu of a septic tank provided a primary settling component is incorporated
into the design, may be allowed or required, at the discretion of an
administrative authority, for new construction, projects where there is an
increase in the expected volume of sanitary sewage pursuant to
7:9A-7.4, or to alter an existing,
malfunctioning system. For individual systems with expected volumes of sanitary
sewage less than or equal to 1,500 gallons per day, advanced wastewater
pretreatment devices shall have obtained an NSF Standard 40 and/or Standard 245
certification, bear the mark of NSF and must be used in accordance with all
conditions of that certification in addition to the requirements in this
chapter. For systems with expected volumes of sanitary sewage greater than
1,500 gpd or systems that receive waste flows that are not residential in
nature, advanced wastewater pretreatment devices shall be from a manufacturer
that has obtained an NSF Standard 40 and/or Standard 245 certification for the
treatment technology, be certified by the manufacturer that the technology is
designed to achieve secondary effluent standards for the actual or proposed
waste strength that will be generated at the site and must be used in
accordance with all requirements in this chapter. The Department shall maintain
a list of advanced wastewater pretreatment devices that are applicable under
this section that comply with the following:
1. Any advanced wastewater pretreatment
device manufacturer that wishes to have their device listed by the Department
shall submit a written request and a copy of an NSF Final Report. The written
request shall include an acknowledgement by the manufacturer to comply with all
applicable requirements of this chapter.
2. Listed manufacturers shall make available
up-to-date training, design, installation and service manuals and materials to
any administrative authority or the Department upon request.
3. All advanced wastewater pretreatment
devices shall be used in accordance with the provisions of this chapter and all
documentation in the NSF Final Report provided to the Department.
(b) Prior to submitting any design
that includes an advanced wastewater pretreatment device to the administrative
authority, a system designer shall:
1.
Certify in the application that they are sufficiently knowledgeable of the
technology(ies) to design the system;
2. Design systems that include advanced
wastewater pretreatment devices in a manner which meets all manufacturer's
minimum specifications and/or recommendations;
3. Design all advanced wastewater
pretreatment devices so that the raw wastewater cannot be discharged without
first being properly treated by the treatment unit as it was designed. The
design shall provide that the liquid levels in the tanks or other treatment
vessels shall be monitored by a properly functioning high level alarm and any
other monitoring equipment or alarm as recommended by the
manufacturer;
4. Utilize the
manufacturer's recommendations for sizing of the advanced wastewater
pretreatment whenever a discrepancy occurs between the estimated volume of
sanitary sewage calculated in accordance with
7:9A-7.4 and the manufacturer's
recommended sizing of the advanced wastewater pretreatment device. Sizing of
all other components of the system shall conform to this chapter;
5. For non-residential systems, obtain a
letter from the manufacturer, or the manufacturer's representative, and provide
it to the administrative authority, verifying the design's consistency with all
manufacturer's minimum specifications and recommendations. The administrative
authority may require the septic system designer to obtain a letter from the
manufacturer, or the manufacturer's representative, for residential systems and
provide it to the administrative authority, verifying the design's consistency
with all manufacturer's minimum specifications and recommendations;
6. Include in the design of the system a
control panel that tracks, at a minimum, pump elapsed time, cycle counts and
high level alarm counts or other means to determine flow through the system and
any other system information for troubleshooting purposes as recommended by the
manufacturer.
i. Systems may be equipped with
a telemetry control panel, attached to an Internet-based interface that
provides continuous remote monitoring, information management and control of
the advanced wastewater pretreatment device; or
ii. Systems that do not have a telemetry
control panel shall use an active phone line equipped with an auto dialer to
notify the authorized service provider of alarm conditions, including if power
to any of the system equipment is disconnected;
7. Design the system so that all processing
tanks, discharge tanks and related treatment unit(s) shall maintain the same
minimum separation distances as required for septic tanks at
7:9A-4.3;
8. Include in the system design only advanced
wastewater pretreatment devices that are watertight. All advanced wastewater
pretreatment devices must be designed in a manner that considers all structural
issues including, but not limited to, venting of the disposal area, load
bearing, buoyancy and all other structural effects on the treatment unit for
the intended installation;
9.
Include in the design a septic tank prior to any advanced wastewater
pretreatment devices unless otherwise specifically identified in the NSF
Standard 40 or 245 certification and the manufacturer's recommendations or
specifications. Effluent filters required at
7:9A-8.2 may be relocated to
another point downstream of the septic tank or may be eliminated provided that
this design consideration is specifically identified in the manufacturer's
recommendations or specifications;
10. Include within any system that
incorporates an advanced wastewater pretreatment device a method of sampling
wastewater after the advanced wastewater pretreatment device to monitor
effluent quality after final treatment has been achieved. This method of
sampling must be achievable at final grade without excavation; and
11. Note in the design all installation
requirements in (c) below, and all maintenance and monitoring requirements
required by
7:9A-12.3.
(c) The following requirements are applicable
to the installation of an advanced wastewater pretreatment device:
1. An authorized installer shall be
physically present at all times during installation of an advanced wastewater
pretreatment device and either install or directly oversee the installation of
the advanced wastewater pretreatment device.
2. The authorized installer shall ensure that
the property owner has been provided with a copy of the service contract and
agrees to comply with the requirements therein by obtaining their written
