If pretreatment or control of wastewater flow is required, such facilities shall be maintained continuously in satisfactory and effective operation at the expense of the owner and in compliance with this chapter. Monitoring of the pretreatment facilities discharge shall be in compliance with Article
VII.
Interceptors (commonly called "traps") for the treatment of grease, oil and solids shall be provided and maintained by the user when the existing or proposed discharge exceeds the limits specified in: §
135-22A (flammable), §
135-22D (solids) and §
135-22E (grease or oil), or when deemed necessary by the Superintendent to protect the operation and efficiency of the wastewater treatment system. Establishments for which such interceptors shall be required include but are not limited to: commercial kitchens such as for restaurants and banquet facilities; gas stations; and motor vehicle maintenance garages. Grease and oil traps shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, watertight and equipped with easily removable covers which, when secured in place, shall be gastight and watertight. Interceptors shall not be required for the discharge of normal domestic wastes from residential users. All interceptors shall be of a type and capacity approved by the Superintendent and the burden of proof of adequacy shall be the responsibility of the owner. All interceptors shall be located so as to be readily and easily accessible for cleaning and inspection.
Each industrial user shall provide protection from accidental
discharge of prohibited materials or other wastes regulated by this
chapter. Facilities to prevent accidental discharge of prohibited
materials shall be provided and maintained at the owner's own cost
and expense. Detailed plans showing facilities and operating procedures
to provide this protection shall be submitted to the Superintendent
for review and shall be approved before construction of such facilities.
Review and approval of such plans and operating procedures shall not
relieve the industrial user from the responsibility to modify this
facility as necessary to meet the requirements of this chapter.
If, for any reason, a facility does not comply with or will
be unable to comply with any prohibition or limitations in this chapter,
the facility responsible for such discharge shall immediately notify
the Superintendent so that corrective action may be taken to protect
the wastewater treatment system. In addition, a written report addressed
to the Town detailing the date, time and cause of accidental discharge,
the quantity and characteristics of the discharge and corrective action
taken to prevent future discharges, shall be filed by the responsible
industrial user within five days of the occurrence of the noncomplying
discharge.
The Superintendent shall have the right to inspect and/or test any building sewer and building drain and appurtenances or private sewers that discharge wastewater directly or indirectly to the Town's wastewater treatment system. This includes the authority to inspect basements for illegal connections such as sump pumps. In the case of basement inspection, the Superintendent shall give prior notice of no less than 12 hours nor more than 48 hours if requested by the owner. If it is found that such sewers or drains are used or maintained in such a way as to cause any discharge that violates this chapter, the Superintendent will initiate enforcement actions in accordance with Article
XIII.
All costs incurred by the Town in carrying out the control actions
specified in this article shall be the responsibility of the actual
or proposed user. These costs shall include but not be limited to
such items as: laboratory tests and consultant services. The Town
will invoice the owner for its costs.
Nothing in this article shall be construed as preventing any special agreement or arrangement, not inconsistent with the Act and rules and regulations of this chapter, between the Town and any user of the wastewater treatment system whereby wastewater of unusual strength or character is accepted into the system and specially treated, subject to any additional payments or user charges as may be applicable. This approval shall be in accordance with Article
V, §
135-23. No special agreements shall circumvent federal categorical pretreatment standards.
