8. A discussion of the contingency disposal options to be utilized if the composted end product cannot be marketed. These disposal options shall be in accordance with the approved district solid waste management plan and Departmental requirements established for the distribution of sewage sludge compost, if applicable;

9. A process flow diagram of the proposed processing steps involved in recovering recyclable materials and mixed organic material from solid waste, any processing of recovered recyclable materials, and the composting, curing and storage of the mixed organic faction;

10. Profile views of all structures and enclosures showing dimensions;

11. In addition to the requirements of N.J.A.C. 7:26-2.10(b)9, the operation and maintenance manual for the facility shall include the following information:

i. A description of the anticipated types, quantity, variation over time, and sources of waste to be received and a description of any additives used in the process;

ii. Designation of persons responsible for operation, control and maintenance of facility;

iii. Methods for measuring incoming waste;

iv. Methods to control the types of waste received (for example, inspection procedures);

v. Methods for removing and recovering for recycling or disposing of non-compostable wastes from the incoming waste stream, including procedures for removal, storage and disposal of any hazardous wastes;

vi. Methods to control traffic and to expedite unloading;

vii. Methods to maintain biological conditions;

viii. Methods to minimize, manage and monitor odors;

ix. Leachate and National Pollutant Discharge Elimination System storm water control measures;

x. Vector, dust and litter control measures;

xi. Contingency operations plan (in the event of equipment failure, power outages, natural disasters, fire, receipt of prohibited materials), including designation of permitted disposal sites for incoming waste, leachate, and for hazardous wastes;

xii. Plans for monitoring, sampling and testing the composting materials for process control and product quality assurance as specified at N.J.A.C. 7:26-2B.7(i); and

xiii. Plans for marketing the finished compost; and

12. A final closure plan containing a schedule and description of the steps necessary to close the facility and financial assurance information.

(d) If a natural ground surface is to be used for storage or if any surface impoundments, lagoons, or other structures for storage or conveyance of leachate, runoff or condensate are proposed, soil borings of the property shall be provided in accordance with the following:

(e) The site plan map shall depict the facility layout on the property and include profile views of all structures, utilities and enclosures showing height, breadth and bulk dimensions. Dimensions for loading, unloading, storage (for example, incoming waste, outgoing product), processing, composting and curing areas shall be provided. Identify the type of drainage system, run-off and leachate control systems. Building setbacks and the distances of any onsite proposed or existing structure, processing area or treatment area, and streets from the site boundaries shall be indicated.
