N.J. Admin. Code § 7:14A-21.12 - Requirements for dental facilities
(a) This section
establishes best management practices and regulatory requirements for owners of
dental facilities that generate amalgam waste through the removal or placement
of amalgams. The requirements of this section do not apply to a dental facility
at which no dentistry is practiced other than any of the following specialties:
1. Orthodontics;
2. Periodontics;
3. Endodontics;
4. Oral and Maxillofacial Surgery;
5. Oral and Maxillofacial Radiology;
and
6. Oral and Maxillofacial
Pathology.
(b) Except as
provided under (c) below, an owner of any dental facility that generates
amalgam waste shall be exempt from the requirement to obtain a NJPDES-SIU
permit from the Department or the delegated local agency for the discharge of
wastewater into a local agency's treatment works, provided the owner complies
with following requirements:
1. The owner of
a dental facility shall implement the best management practice described in (d)
below no later than October 1, 2008;
2. The owner of the dental facility shall
install an amalgam separator to serve every dental chair in the facility where
amalgam waste is generated. The amalgam separator must be adequately sized for
the maximum expected flow rate. The amalgam separator shall be installed no
later than October 1, 2009. The separator shall conform with the ISO 11143
protocol. Each dental facility constructed on or after October 1, 2007 shall
include an installed amalgam separator that conforms with the ISO 11143
protocol. A separator shall be deemed to meet to the required ISO protocol if
it conforms to the ISO 11143 protocol issued in 1999 or later; and
3. The owner of a dental facility subject to
this section shall register and certify compliance with the requirements of
(b)1 and 2 above. This registration and certification shall be submitted
annually to the Department on forms or in the format provided by the
Department.
(c) If a
local agency conducts a headworks analysis pursuant to
7:14A-19.7(a) and
determines that additional mercury control measures are necessary to ensure
compliance with its NJPDES permit, then the control authority shall impose
additional mercury control measures on dischargers to the local agency's
treatment works, including, as appropriate, dental facilities subject to this
section. Where additional mercury control measures are necessary, all dental
facilities discharging to such local agency shall apply for a NJPDES-SIU
permit.
(d) Best management
practices require a dental facility to, at a minimum:
1. Use mercury-free material when
appropriate;
2. Eliminate all use
of bulk elemental mercury;
3. Use
precapsulated alloys only;
4.
Recycle used disposable capsules containing amalgam;
5. Maintain and operate the amalgam separator
when installed according to its manufacturer's specifications;
6. Install chair-side traps in both the
vacuum system and cuspidor of each operatory where restoration work is
done;
7. Change and clean
chair-side traps frequently;
8. Not
rinse traps or vacuum pump filters over drains or in the sinks;
9. Not throw or place the disposable trap,
sludge from reusable trap, or vacuum pump filter or contents with regular
garbage;
10. Not throw or place the
disposable trap, sludge from reusable trap, or vacuum pump filter or contents
into sharps containers or biohazard bag;
11. Not flush amalgam waste down the
drain;
12. Use only non-bleach,
non-chlorine cleaners to clean vacuum system lines;
13. Appropriately disinfect and store amalgam
pieces from removal and restoration with amalgam waste;
14. Store amalgam waste in airtight
containers;
15. Have a licensed
recycling contractor, mail-in service or hazardous waste hauler remove amalgam
waste;
16. Recycle all amalgam
waste containing mercury;
17. Train
staff in the proper handling, management, and disposal of mercury containing
material; and
18. Keep records to
document that the BMP requirements are being met.
