All requested documentation shall be made available to the Township upon request.
Education. All kitchen employees whose job responsibilities may impact the grease control plan must be trained on the requirements of the facility's plan. A written verification of training shall be retained by the facility during the employee's term of employment with the facility and for three years thereafter.
Posting. Drains that are not directed through a grease interceptor and are located in high grease handling areas of commercial kitchens shall be affixed with a nonabsorbent posting stating "No Grease."
Authorized representatives of the Township, including but not limited to personnel of the Department of Public Works, Health Department, Plumbing Subcode Official, and Office of the Township Engineer or designated representatives, shall be permitted to enter and inspect all properties that are required to have a grease control plan. This right of investigation and inspection shall include the right to measure, observe, monitor, video (with a sewer camera if deemed necessary by the inspector), photograph, sample, test, record, review and make copies of all pertinent documents.
The owner of the property or establishment shall maintain on-site the tools necessary to gain access to grease interceptors, monitoring pits and inspection ports.
In the event it is determined that a blockage or interference of the Township sewer system is the result of the discharge from any FOG-generating property, all costs incurred by the Township will be charged to the owner and/or tenant. Such costs may include, but are not limited to, costs of investigating the source of and clearing the blockage/interference; damages to sewer lines and pump stations; laboratory testing; administrative, legal and engineering costs, cleanup of pollution to surrounding soils or water and reimbursement of any penalties imposed by regulatory agencies.
In locations where the property owner differs from the business owner, both parties shall be jointly and separately responsible for ensuring that prohibited items are not discharged into the sewer system.
Unless otherwise provided herein, penalties for violations of this article shall be as set forth in Chapter 1, General Provisions, Article II, Penalty, § 1-3.
If a violation results from a prohibited discharge or grease blockage in the Township's sewer system, the Township may require design improvements in addition to the penalties assessed.
If a prohibited discharge and/or blockage/interference is a repeat violation, the Township may require the installation of an audiovisual alarm system equipped with a means of recording and identifying when the storage capacity which allows for efficient operation of the grease interceptor system has been exceeded.
If a prohibited discharge and/or blockage occurs two or more times within a twelve-month period, the violator will be required, under the direction of a licensed design professional, to investigate the source of the prohibited discharge and implement an improved grease control plan to prevent future prohibited releases. The written improved grease control plan shall be submitted to the Township within 30 calendar days of receipt of the notice of violation for approval. Remedial management plans shall be implemented immediately.
Upon written notification by the Township of mandated design improvements due to an illegal release of FOG into the sewer system or a documented grease blockage or interference, the owner/operator shall install and maintain said improvements within 90 days. Failure to comply within the allotted time period shall be considered a violation of this article.
