A. 
Users shall provide wastewater treatment as necessary to comply with this Ordinance, and shall achieve compliance with all limits, prohibitions, and requirements set out in Sections 2.4, 2.5, and 2.6 within the time limitations specified by the EPA, the State, or the Director, whichever is most stringent.
B. 
All facilities required to achieve and maintain compliance shall be provided, operated, and maintained at the user's expense.
C. 
Detailed plans describing such facilities and operating procedures shall be submitted to the Director for review, and shall be acceptable to the Director and the State 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 Town under the provisions of this Ordinance.
D. 
Plans and specifications for a proposed pretreatment facility shall be signed and sealed by a professional engineer licensed by the State of New Hampshire.
A. 
Whenever deemed necessary, the Director 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 waste streams from industrial waste streams, and impose such other conditions as are deemed necessary to protect the POTW and determine the user's compliance with the requirements of this Ordinance.
B. 
The Director may require any person discharging into the POTW 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. 
Fats, Oils, and Grease (FOG), and Sand Interceptors. Interceptors for fats, oils, grease, sand or other substances harmful or hazardous to the building sewer or POTW shall be provided at the owner's expense when, in the opinion of the Director, such devices are necessary for the preliminary treatment of wastewater containing excessive amounts of fats, oils, grease, and/or sand, except that such interceptors shall not be required for solely residential users.
1. 
Concentrated grease and oils from fryers, grill and stove grease accumulation traps and vent hoods shall be properly disposed of or recycled, and shall not be discharged to the sewer.
2. 
All new food service establishments (including, but not limited to restaurants, hotel kitchens, hospital kitchens, school kitchens, bars, factory cafeterias and clubs), and any other facility discharging fats, oils, and grease above the discharge limit described in Article II shall be served by:
i. 
An external FOG interceptor, subject to the Director's approval, installed on a separate building sewer line servicing kitchen flows and connected only to an approved fixture or drain.
ii. 
If an external interceptor is not practical, FOG-bearing wastewaters shall be served by an indoor automated grease recovery unit (or units) that separates grease from the wastewater by active mechanical or electrical means, and are subject to the Director's approval.
3. 
Existing food service establishments undergoing significant renovation, or those designated in sewer service areas experiencing problems, such as grease blockages, may be required by the Director to install or upgrade a FOG removal system to satisfy the requirements of these regulations.
All interception units shall be of a type and capacity approved by the Director and shall be so located as to be easily accessible for cleaning and inspection by the owner and the Town. Grease traps shall conform to the Plumbing and Drainage Institute Standard PDI-G101 and shall be installed in accordance with the manufacturer's instructions. Maintenance of interceptors requires that the owner be responsible for the proper removal and disposal by appropriate means of the captured materials, in accordance with the requirements established by the Director. The owner shall maintain service records of the interceptors. The form and content of such records will be determined by the Director and the records shall be subject to periodic review by the Director. The removal and disposal of captured materials from interceptors shall be performed by an approved hauler at a legally licensed facility and proof of such placement shall be provided in writing to the owner who shall maintain such record of disposal for inspection by the Town.
D. 
Users with the potential to discharge flammable substances shall, at the discretion of the Director, 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 in satisfactory and effective operation by the owner.
F. 
Monitoring Facilities. The owner of any building services or a building sewer carrying industrial wastes may, at the discretion of the Director, be required to install a suitable control manhole or approved equivalent structure together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. Such structures, when required, shall be accessible, safely located, and shall be constructed in accordance with this Ordinance and NHDES Env-Wq 700, and will be subject to approval by the Director. The owner shall perform such monitoring as the Town may reasonably require, including: the installation, use and maintenance of monitoring equipment; records maintenance; and reporting the results of such monitoring to the Town. Such records shall be provided to the Town.
G. 
The Director shall develop, implement, and enforce such administrative rules that may be approved by the Board of Selectmen, as is determined to be necessary to manage the discharge of fat, oil, and grease into the municipal sewer system. The rules shall address the generation of grease-laden wastewaters by food production and food service establishments, the installation and operation of grease removal equipment, and the disposal of grease wastes.
H. 
Dental practice which manages dental amalgam shall install and maintain an amalgam separator in accordance with federal and/or state regulations.
A. 
All industrial users shall provide protection from accidental discharge of prohibited materials or other wastes regulated by this Ordinance. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the user's cost and expense.
B. 
The Director may periodically evaluate whether a user needs an accidental discharge/slug control plan. The Director may require any use to develop, submit for approval, and implement such a plan. Review and approval of such plans and operating procedures shall not relieve the industrial user from the responsibility to modify his facility as necessary to meet the requirements of this Ordinance. Alternatively, the Director may develop such a plan for any user. An accidental discharge/slug control plan shall address, at a minimum, the following:
1. 
A description of discharge practices, including non-routine batch discharges;
2. 
A description of all stored chemicals;
3. 
Procedures for immediately notifying the Director of any accidental or slug discharge, as required by Section 6.3 of this Ordinance; and
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 pollutants, including solvents, and/or measures and equipment for emergency response.
The Director may require any person discharging wastes into the POTW to develop and implement, at their own expense, a pollution prevention plan. The Director may require users to submit as part of the pollution prevention plan information that demonstrates adherence to the following elements:
A. 
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 waste streams, and procedures for employee training and involvement.
B. 
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.
C. 
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.
D. 
Analysis of Waste Management Economics. Waste management economic returns shall be determined based on the consideration of:
1. 
Reduced raw material purchases;
2. 
Avoidance of waste treatment, monitoring and disposal costs;
3. 
Reductions in operations and maintenance expenses;
4. 
Elimination or reduction of permitting fees and compliance costs; and
5. 
Reduced liabilities for employee/public exposure to hazardous chemicals and cleanup of waste disposal sites.
E. 
Development of Pollution Prevention Alternatives. Current and past pollution prevention activities shall be assessed, including estimates of the reduction in the amount and toxicity of waste achieved by the identified actions. Opportunities for pollution prevention shall then be assessed for identified processes where raw materials become or generate wastes. Technical information on pollution prevention shall be solicited and exchanged, both from inside the organization and out.
F. 
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.
G. 
Recordkeeping. Documentation demonstrating implementation or compliance with the pollution prevention plan shall be created, retained, and made available as required by the Director.
The review and approval of such pollution prevention plans by the Town shall in no way relieve the user from the responsibilities of modifying their facilities as necessary to produce a discharge acceptable to the Town in accordance with the provisions of this Ordinance.
