(d) Signed statement that the operator will maintain records of waste disposal and produce them for compliance inspections.
(3) Self-cleaners must adhere to all the requirements; procedures and detailed record keeping outlined in their approved application, to ensure compliance with this subchapter. A maintenance log shall be kept by self-cleaning operators that indicates, at a minimum, the following information:
(a) Date the grease trap/interceptor was serviced;
(b) Name of the person or company servicing the grease trap/interceptor;
(c) Waste disposal method used;
(d) Gallons of grease removed and disposed of;
(e) Waste oil added to grease interceptor waste; and
(f) Signature of the operator after each cleaning that certifies that all grease was removed, disposed of properly, grease trap/interceptor was thoroughly cleaned, and that all parts were replaced and in operable condition.
(4) Violations incurred by grease interceptors self-cleaners will be subject to enforcement action including fines and/or removal from the self-cleaner program.
(D) Cleaning schedules.
(1) Grease interceptors shall be cleaned as often as necessary to ensure that sediment and floating materials do not accumulate to impair the efficiency of the grease interceptor; to ensure the discharge is in compliance with local discharge limits; and to ensure no visible grease is observed in discharge.
(2) Grease interceptors shall be completely evacuated a minimum of every 30 days, or more frequently when:
(a) Twenty-five percent or more of the wetted height of the grease trap or grease interceptor, as measured from the bottom of the device to the invert of the outlet pipe, contains floating materials, sediment, oils or greases; or
(b) If there is a history of non-compliance.
(3) Any person who owns or operates a grease interceptor may submit to the POTW a request in writing for an exception to the 30 day cleaning frequency of their grease interceptor. The POTW may grant an extension for required cleaning frequency and establish a specific cleaning schedule on a case-by-case basis when less than 25% of the wetted height of the grease interceptor, as measured from the bottom of the device to the invert of the outlet pipe, contains floating materials, sediment, oils or greases.
(E) Manifest requirements.
(1) Each pump-out of a grease interceptor must be accompanied by a manifest to be used for record keeping purposes.
(2) Persons who generate, collect and transport grease waste shall maintain a record of each individual collection and deposit. Such records shall be in the form of a manifest. The manifest shall include:
(a) Name, address, telephone, and registration number of transporter;
(b) Name, signature, address, and phone number of the person who generated the waste and the date collected;
(c) Type and amount(s) of waste collected or transported;
(d) Name and signature(s) of responsible person(s) collecting, transporting, and depositing the waste;
(e) Date and place where the waste was deposited;
(f) Identification (permit or site registration number, location, and operator) of the facility where the waste was deposited;
(g) Name and signature of facility on-site representative acknowledging receipt of the waste and the amount of waste received;
(h) The volume of the grease waste received; and
(i) A consecutive numerical tracking number to assist transporters, waste generators, and regulating authorities in tracking the volume of grease transported.
(3) Manifests shall be divided into five parts and records shall be maintained as follows.
(a) One part of the manifest shall have the generator and transporter information completed and be given to the generator at the time of waste pickup.
(b) The remaining four parts of the manifest shall have all required information completely filled out and signed by the appropriate party before distribution of the manifest.
(c) One part of the manifest shall go to the receiving facility.
(d) One part shall go to the transporter, who shall retain a copy of all manifests showing the collection and disposition of waste.
