Industrial users shall provide necessary wastewater treatment as required to comply with this chapter and shall achieve compliance with all categorical pretreatment standards, local limits and the prohibitions set out in § 73-12 above within the time limitations specified by the EPA, the applicable state or the Executive Director, whichever is more stringent. Any facilities required to pretreat wastewater to a level acceptable to the PSA shall be provided, operated and maintained at the industrial user's expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the PSA for review and shall be acceptable to the PSA before construction of the facility. The review of such plans and operating procedures will in no way relieve the industrial user from the responsibility of modifying the facility as necessary to produce an acceptable discharge to the PSA under the provisions of this chapter.
A. 
Whenever deemed necessary, the Executive Director may require industrial 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 such other conditions as may be necessary to protect the POTW and determine the industrial user's compliance with the requirements of this chapter.
B. 
Each person discharging into the POTW greater than 100,000 gallons per day or greater than 4% of the average daily flow in the POTW, whichever is the lesser (or a lesser amount in the event that the Executive Director determines that the discharge is greater than can be handled by the collector or interceptor system or the POTW), shall install and maintain, on his property and at his expense, a suitable storage and flow-control facility to ensure equalization of flow over a twenty-four-hour period. The facility shall have a capacity for at least 30% of the daily discharge volume and shall be equipped with alarms and a rate-of-discharge controller, the regulation of which shall be directed by the Executive Director. A wastewater discharge permit may be issued solely for flow equalization.
C. 
Grease, oil and sand separators shall be provided when, in the opinion of the Executive Director, they are necessary for the proper handling of wastewater containing excessive amounts of grease, oil or sand, except that such separators shall not be required for residential users. All interception units shall be of a type and capacity approved by the Executive Director 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 owner, at the owner's expense.
(1) 
Grease traps shall be provided for all restaurants and similar establishments where the quantity of grease and fats in liquid wastes is likely to be large or at the direction of the Executive Director.
(2) 
The grease trap shall be located within 30 feet of the source in order to prevent grease from congealing in the collection system.
(3) 
Only those plumbing fixtures into which the grease and fats are to be discharged are to be connected to the grease trap, and no other plumbing fixture shall be connected to the grease trap.
(4) 
The grease trap shall have a capacity of 150 gallons or three gallons per meal served during the peak meal time, whichever is greater. Capacity of grease traps at restaurants shall be established on a case-by-case basis by the Executive Director.
(5) 
Units may be built on site as approved by the Executive Director or following septic tank criteria and shall be baffled or teed to prevent effluent flow from disturbing the floating grease layer, with the length of the inlet baffle or tee to be 20% of the liquid depth, submerged inlets being prohibited. Outlets shall be 80% or more of liquid depth to prevent organics from settling cut and to provide maximum storage of floatable material. A tee shall be placed vertically on the floor of the unit and fitted to join with the outlet tee to provide support for the outlet structure. The invert of the inlet structure should be greater than one inch but less than two inches higher than the outlet structure with the tank installed. The inlet and outlet structure shall extend 10 inches above the normal liquid level. Materials used for the inlet and outlet structures shall have long-term resistance to chemical and electrolytic corrosion and shall be compatible with the material used in the sewer system. Tanks must be watertight with access manholes over the inlet and outlet structures with a minimum open space of 18 inches by 18 inches. In wet areas, manhole covers must be watertight. The units must be skimmed periodically and otherwise properly maintained and kept in good working order. A typical plan for such units is included in the PSA schematic, which is on file in the offices of the PSA.
[Amended 4-7-1997]
D. 
Industrial users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas-detection meter.
E. 
At no time shall two readings on an explosion-hazard meter at the point of discharge into the POTW or at any point in the POTW be more than 30%, nor shall any single reading be over 50% of the lower explosive limit (LEL) of the meter.
A. 
Each user shall provide protection from accidental discharge of prohibited materials or other substances regulated by this chapter. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the owner or user's own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the PSA for review and shall be approved by the PSA before construction of the facility. No user who commences contribution to the POTW after the effective date of this chapter shall be permitted to introduce pollutants into the system until accidental discharge procedures have been approved by the PSA. Review and approval of such plans and operating procedures shall not relieve the user from the responsibility to modify the user's facility as necessary to meet the requirements of this chapter. In the case of an accidental discharge, it is the responsibility of the user to immediately telephone and notify the POTW of the incident. The notification shall include the location of discharge, type of waste, concentration and volume, and corrective actions.
B. 
Within five days following an accidental discharge, the user shall submit to the Executive Director a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage or other liability which may be incurred as a result of damage to the treatment works and treatment facility, fish kills or any other damage to person or property; nor shall such notification relieve the user of any fines, civil penalties or other liability which may be imposed by this section or other applicable law.
C. 
A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees whom to call in the event of a dangerous discharge. Employers shall ensure that all employees who may cause or suffer such a discharge to occur are advised of the emergency notification procedure.
D. 
The Executive Director may require any industrial user to develop and implement an accidental discharge/sludge control plan. At least once every two years, the Executive Director shall evaluate whether each significant industrial user needs such a plan. Any industrial user required to develop and implement an accidental discharge/control sludge plan shall submit a plan which addresses, at a minimum, the following:
(1) 
A description of discharge practices, including nonroutine batch discharges.
(2) 
A description of stored chemicals.
(3) 
Procedures for immediately notifying the POTW of any accidental or sludge discharge. Such notification must also be given for any discharge which would violate any of the prohibited discharges in § 73-12 of this chapter.
(4) 
Procedures to prevent adverse impact from any accidental or sludge 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 of equipment, measures for containing toxic organic pollutants (including solvents) and/or measures and equipment for emergency response.
The PSA may adopt reasonable charges and fees for reimbursement of costs of setting up and operating the PSA's pretreatment program, which may include:
A. 
Fees for wastewater discharge permit applications, including the cost of processing such applications.
B. 
Fees for monitoring, inspection and surveillance procedures, including the cost of collection and analyzing an industrial user's discharge and reviewing monitoring reports submitted by industrial users.
C. 
Fees for reviewing and responding to accidental discharge procedures and construction.
D. 
Fees for filing appeals.
E. 
Other fees as the PSA may deem necessary to carry out the requirements contained herein. These fees relate solely to the matters covered by this chapter and are separate from all other fees, fines and penalties chargeable by the PSA.
[Amended 4-7-1997]
Where an owner of property leases premises to any other person as a tenant under any rental or lease agreement, if either the owner and/or the tenant is also an industrial user, either or both may be held responsible for compliance with the provisions of this chapter.
A. 
Septic tank waste may be accepted into the POTW at a designated receiving structure within the treatment plant area and at such times as are established by the Executive Director, provided that such wastes do not violate § 73-12 of this chapter or any other requirements established or adopted by the PSA. Wastewater discharge permits for individual vehicles to use such facilities shall be issued by the Executive Director.
B. 
The discharge of hauled industrial wastes as industrial septage requires prior approval and a wastewater discharge permit from the PSA. The Executive Director shall have the authority to prohibit the disposal of such wastes, if such disposal would interfere with the treatment plant operation. Waste haulers are subject to all other sections of this chapter.
C. 
Fees for dumping septage will be established as part of the industrial user fee system as authorized in § 73-16.
No person shall maliciously, willfully, recklessly or negligently break, damage, destroy, uncover, deface, tamper with or prevent access to any structure, appurtenance or equipment or other part of the POTW. Any person found in violation of this requirement shall be subject to the sanctions set out in § 73-73 below.
