description of the selected waste treatment system;
2. For the modification of an existing system
which has not previously been granted a treatment works approval, the
capacities of the existing units and a brief description of the operation of
each, and a statement concerning which units are existing and which are
proposed at the time of the application. If there exists a previously issued
treatment works approval for the subject facility, the date of issuance and the
TWA number shall be provided;
3.
The basis and computations for the projected wastewater flow;
4. Hydraulic profiles of the flow of
wastewater through the system;
5. A
unit by unit mass balance for all discharge parameters;
6. The ultimate disposal location of all
effluent;
7. The basis and
computations for average and peak flow requirements;
8. The expected composition of the influent
and effluent from the treatment system including the average, maximum and
minimum values of the pollutant parameters specified in the facility's NJPDES
permit;
9. An evaluation of the
quantity and quality of any and all residuals generated and projected to be
generated, including a hydraulic profile and unit by unit mass balance for the
flow of residuals through the system;
10. Documentation of adequate storage and
handling facilities for residuals;
11. Provisions for the ultimate management of
residuals pursuant to the State Solid Waste Management Plan and/or the
Statewide Sludge Management Plan, as applicable. For proposed upgrading or
expansion of domestic treatment works, sludge management planning forms may be
submitted pursuant to the Statewide Sludge Management Plan, Appendix K, to
satisfy this requirement;
12.
Details of flow monitoring and control, alarm systems, auxiliary power, storage
facilities for treatment chemicals and wastes, and a plan for bypassing units
during construction or maintenance; and
13. A signed and sealed statement from the
New Jersey licensed professional engineer who designed the treatment works
attesting to the proposed treatment works' ability, as designed, to meet the
requirements of this subchapter and to attain all applicable discharge
limits.
(b) For treatment works applications involving the temporary or permanent use of holding tanks, the engineering reports required to be submitted by N.J.A.C. 7:14A-22.13 and 22.8 shall include:
1. A description of the high water alarm to
be provided to alert the responsible persons that the holding tank has reached
75 percent of its capacity and which will allow sufficient time to take
appropriate measures to prevent overflows;
2. A description of provisions for aeration
at a rate of two cubic feet per minute per 1,000 gallons to prevent septic
conditions and solids settling;
3.
Identification of a source of washdown water for routine maintenance and
emergency situations, adequately protected by a backflow prevention
device;
4. A description of the
holding tank area, including adequate measures to protect it from vandalism and
safeguards for public health and safety;
5. Engineering drawings containing
construction details for all system components;
6. Specifications including construction
practices and operation and maintenance procedures; and
7. Sizing of holding tanks which, at a
minimum, provides two days of waste storage, as determined in accordance with
the projected flow requirements in
N.J.A.C.
7:14A-23.3.
(c) Engineering reports required to be submitted for projects involving the use of equalization tanks within a collection system, pursuant to N.J.A.C. 7:14A-22.15, shall include the following:
1. A description of the method for placing
the tank into operation and the timing and procedure for releasing the effluent
back into the collection system, including quantity of flow and duration
held;
2. Average and peak flow
requirements;
3. A description of
the high water alarm to be provided to alert the responsible persons that the
equalization tank has reached 75 percent of its capacity and which allows
sufficient time to take appropriate measures to prevent overflows;
4. A description of the equalization tank
area, including adequate measures to protect it from vandalism and safeguards
for public health and safety such as covers, overflow protection, fencing,
etc.;
5. The engineering drawings
containing construction details for all system components; and
6. The specifications including construction
practices and operation and maintenance procedures.
(d) Engineering reports required to be submitted pursuant to N.J.A.C. 7:14A-22.14 and 22.8, for flow diversion, shall include, but are not limited to, the following:
1. The existing and anticipated average and
peak flow events within the collection system;
2. The ultimate disposal location of all
effluent; and
3. A report outlining
the procedures to be used in the hauling/diversion operation, including, but
not limited to, the location at which the wastewater will be withdrawn, the
frequency and time of withdrawal, and the effect that the procedure may have
upon the treatment capabilities of both treatment facilities.
(e) Engineering reports required to be submitted pursuant to N.J.A.C. 7:14A-22.8, for industrial treatment works approval applications shall include, but are not limited to:
1. A complete description of waste treatment
system;
2. A mass balance and, if
temperature change across any unit will exceed 10 degrees Celsius, a heat
balance;
3. The ultimate
destination of all wastewater, sludge and residuals;
4. Average and peak flow requirements and
rationale for design;
5. A listing
of all pollutants, including regular and intermittent flows, and expected
composition that may enter the system;
6. The composition and quality of all sludge
generated, name and registration number of the sludge hauler, frequency and
parameters for periodic analysis;
7. Documentation of adequate storage and
handling facilities for residuals;
8. Provisions for the ultimate management of
residuals pursuant to the State Solid Waste Management Plan and/or the
Statewide Sludge Management Plan, as applicable;
9. The expected composition of effluent from
the treatment system;
10. A listing
of any standards, ordinances, permits, court orders, contracts, etc. which
regulate the discharge;
11. An
evaluation of the capability of the system to meet the most stringent
applicable effluent limitation for each pollutant parameter from the NJPDES
permit or other authorizations such as an administrative or judicial consent
order;
12. Potential spills from
within the industrial facility which may enter the treatment system and
provisions for treatment and containment;
13. Provisions for metering and monitoring of
