Users shall provide wastewater treatment as necessary to comply with this chapter and shall achieve compliance with all local limits, prohibitions and requirements set out in § 136-10, Prohibited discharge standards, § 136-11, Federal categorical pretreatment standards, and § 136-12, Local discharge restrictions, of this chapter, within the time limitations specified by the EPA, the state or the Director of Public Works, whichever is more stringent. All facilities required to achieve and maintain compliance shall be provided, operated and maintained at the user's expense. Detailed plans describing such facilities and operating procedures shall be submitted to the Director of Public Works for review, and shall be acceptable to the Director of Public Works and the NHDES before such facilities are constructed. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the city under the provisions of this chapter.
A. 
Whenever deemed necessary, the Director of Public Works may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams and such other conditions as may be necessary to protect the Lebanon Treatment Works and determine the user's compliance with the requirements of this chapter.
B. 
The Director of Public Works may require any person discharging into the Lebanon Treatment Works to install and maintain, on their property and at their expense, a suitable storage and flow-control facility to ensure equalization of flow. An industrial discharge permit may be issued solely for flow equalization.
C. 
Grease, oil and sand interceptors shall be provided at the owner's expense when, in the opinion of the Director of Public Works, these devices are necessary for the preliminary treatment of wastewater containing excessive amounts of grease and oil, or sand; except that such interceptors shall not be required for residential users. All interception units shall be of a type and capacity approved by the Director of Public Works and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned and repaired regularly, as needed, by the user at their expense. Maintenance of these interceptors requires that the owner be responsible for the proper removal and disposal by appropriate means of the captured materials and shall maintain records of the dates and means of disposal, which shall be subject to periodic review by the Director of Public Works. Any removal and hauling of the collected materials shall be performed by currently licensed waste disposal firms.
D. 
Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter and alarm.
E. 
Where pretreatment or flow equalizing facilities are provided or required for any waters or wastes, these devices shall be maintained continuously to ensure satisfactory and effective operation by the owner at his expense.
A. 
At least once every two years, the Director of Public Works shall evaluate whether each significant industrial user needs an accidental discharge/slug control plan. The Director of Public Works may require any user to develop, submit for approval and implement such a plan. Alternatively, the Director of Public Works may develop such a plan for any user.
B. 
An accidental discharge/slug control plan shall address, at a minimum, the following:
(1) 
Description of discharge practices, including nonroutine batch discharges.
(2) 
Description of stored chemicals.
(3) 
Procedures for immediately notifying the Director of Public Works of any accidental or slug discharge, as required by § 136-40, Reports of slug/potentially adverse discharges, of this chapter.
(4) 
Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and/or measures and equipment for emergency response.
A. 
In accordance with the provisions of § 136-12, Local discharge restrictions, and § 136-63, Pollution prevention plan development, of this chapter, the Director of Public Works may require any person discharging wastes into the Lebanon Treatment Works to develop and implement, at their own expense, a pollution prevention plan. The Director of Public Works may require users to submit as part of the pollution prevention plan information that demonstrates adherence to the following elements:
(1) 
Management support. For changes to be effective, the visible support of top management is required. Management's support should be explicitly stated and include designation of a pollution prevention coordinator, goals and time frames for reductions in volume and toxicity of wastestreams, and procedures for employee training and involvement.
(2) 
Process characterization. A detailed process waste diagram shall be developed that identifies and characterizes the input of raw materials, the outflow of products and the generation of wastes.
(3) 
Waste assessment. Estimates shall be developed for the amount of wastes generated by each process. This may include establishing and maintaining waste accounting systems to track sources, the rates and dates of generation and the presence of hazardous constituents.
(4) 
Analysis of waste management economics. Waste management economic returns shall be determined based on the consideration of:
(a) 
Reduced raw material purchases;
(b) 
Avoidance of waste treatment, monitoring and disposal costs;
(c) 
Reductions in operations and maintenance expenses;
(d) 
Elimination of permitting fees and compliance costs; and
(e) 
Reduced liabilities for employee/public exposure to hazardous chemicals and cleanup of waste disposal sites.
(5) 
Development of pollution prevention alternatives. Current and past pollution prevention activities should be assessed, including estimates of the reduction in the amount and toxicity of waste achieved by the identified actions. Opportunities for pollution prevention must then be assessed for identified processes where raw materials become or generate wastes. Technical information on pollution prevention should be solicited and exchanged, both from inside the organization and out.
(6) 
Evaluation and implementation. Technically and economically feasible pollution prevention opportunities shall be identified, and an implementation timetable with interim and final milestones shall be developed. The recommendations that are implemented shall be periodically reviewed for effectiveness.
B. 
The review and approval of such pollution prevention plans by the city shall in no way relieve the user from the responsibilities of modifying their facilities as necessary to produce a discharge acceptable to the city in accordance with the provisions of this chapter.
