In every case where a food establishment is preparing or selling food or other business in which FOG is a by-product, a suitable FOG pretreatment system that conforms to the Massachusetts State Plumbing Code, 248 CMR 10.09(2), must be installed according to this section.
The Weymouth Health Department may at any time require the installation, upgrade and/or relocation of a FOG pretreatment system, as it may deem necessary to maintain any particular building sewer pipe, any lateral sewer pipe, or sewer main pipe free from obstructions caused by waste grease or oil emanating from a food establishment. Each establishment must pay all costs for installing and maintaining the systems.
New or substantially remodeled food establishments must install an outdoor/underground grease interceptor, with a minimum capacity of 1,500 gallons, or an indoor automatic grease trap. Both must be sized according to the manufacturer and in compliance with 248 CMR.
NOTE — Passive indoor grease traps will not be permitted.
Internal automatic and passive grease traps must be cleaned monthly (unless a variance is given by the Director) by a professional drain cleaner, licensed plumber, or permitted offal/septage hauler.
Outdoor/Underground grease interceptors must be pumped and inspected by a permitted offal/septage hauler every three months or more frequently so as to prevent any grease blockage.
A copy of the Health Department grease trap maintenance log must be completed and kept on-site for any operation/maintenance to FOG pretreatment systems. The log must be readily accessible for agents and Weymouth officials to review.
All pumping and hauling records must be maintained on a monthly basis and be readily accessible to Weymouth officials.
Waste grease and oil shall not be disposed of by way of the sanitary sewer. All waste grease and oil must be collected in an appropriate container provided by an approved vendor and stored in an approved location on the premises. The container must be stored on an impervious surface such as concrete or pavement. Containers must be capable of being sealed or be stored in a sheltered area to prevent entry of precipitation and vermin. All waste grease and oil shall be removed by a permitted offal/septage hauler; said material should be removed from the premises as needed. While being stored, all grease containers and surrounding areas must be kept in sanitary conditions at all times.
All automatic electrical/mechanical grease removal units shall be sized in accordance with the manufacturer's written recommendations and be in compliance with 248 CMR.
A separate suitable sampling location as approved by the Director or his/her designee shall be provided for sampling the discharge from any indoor passive or automatic system.

Enforcement and inspection.
It shall be the responsibility of agents to review cleaning and maintenance records for all grease removal systems as part of regular food service inspections.
All records pertaining to storage and removal of grease-related waste shall be retained by the owner or operator on premises for no less than two years. Upon request by a Weymouth official, an owner or operator shall furnish all records required to enforce and monitor compliance with this regulation.
Weymouth officials may use oil-soluble dyes to identify (by color) the FOG of any given establishment in order to determine if said establishment is a cause of failure or obstruction in a sewer lateral or main.
Agents may order the suspension of a permit to operate a food establishment or the termination of one or more particular operations for:
Serious or repeated violations of this section;
Interference with the any Weymouth official in the performance of his/her duty;
Failure to maintain required records or keeping or submitting any misleading or false records or documents required by this section.
The effective date and length of a suspension will be determined by the Director.
Two or more suspensions at an individual food establishment may result in the revocation of the permit to operate.
Weymouth officials may inspect a facility if, in their judgment, they feel that there has been an infraction of the discharge limits to the wastewater.
Violation. Written notice of any violation of this section shall be given to the owner and operator by an agent, specifying the nature, time and date of the violation and any preventative measure required to avoid future violations, and a correction time frame.
Variances. The Director may issue variances from the requirements of this section for the following items:
Hearing. The person or persons to whom any order or notice is issued pursuant to this section may request a hearing before the Director. Such request shall be in writing and shall be filed in the office of the Health Department within seven days after receipt.
Severability. If any word, clause, phrase, sentence, paragraph, or section of this regulation shall be declared invalid for any reason whatsoever, that portion shall be severed and all other provisions of this section shall remain in full force and effect.
Time line for connection.
If a food establishment is found to be causing blockage to the municipal sewer system, the Health Department may order the installation of either an indoor automatic grease trap or an underground passive interceptor.
Newly built food establishments or those undergoing substantial renovations must install the appropriate FOG pretreatment system according to this section as part of the building project. Locations of grease traps and interceptors must comply with 248 CMR 10.09(2)(a), (b) and (c).
All other food establishments must install either an indoor automatic grease trap or an outdoor/underground grease interceptor within one year of adoption of this section unless a variance is granted by the Director.
Weymouth Board of Health regulations. The Weymouth Health Department may from time to time promulgate and amend regulations pertaining to the maintenance of grease traps and removal of grease from food establishments. In addition to this section, food establishments are required to adhere to all requirements as set forth in the Health Department regulations. In the event the regulations conflict with any section or subsection of this section, it is this section which shall take precedence.
