The program set forth in this subchapter is necessary because:
(A) Oil and grease can obstruct the flow of wastewater in the collection system by accumulating on the inside walls of pipes;
(B) Oil and grease increase the pollutional load that must be treated at the WWTP. This reduces WWTP efficiency by increasing treatment costs;
(C) Maintenance costs. The town spends additional dollars per year unclogging pipes in the collection system and physically removing oil and grease at WWTP; and
(D) Much of the oil and grease originates with commercial and institutional food preparation establishments.
(Prior Code, § 51.25)
The following must comply with the provisions of this subchapter: all generators of oil and grease, including restaurants, grocery stores that process meat, nursing homes, schools, hospitals, convenient stores that prepare food, public facilities with kitchens, all special use areas that allow cooking, and all facilities that change oil and service motors, unless they are subject to other state or federal oil and grease inspection laws.
(Prior Code, § 51.26) Penalty, see § 10.99
(A) A facility meeting the criteria must possess and maintain a properly sized grease trap interceptor.
(B) All existing facilities that generate oil and grease will be allowed to install under the sink indoor traps and/or automatic traps sized by an engineer or the grease trap manufacturer, but an emphasis will be placed on maintenance records showing that these traps are cleaned daily and documented by employees of the establishment.
(C) All new facilities that generate oil and grease will be required to install, at a minimum, a 750-gallon grease trap interceptor sized by an engineer or the grease trap manufacturer.
(D) Town staff will not be responsible for actual sizing of any traps. This will be performed by the business having the trap installed.
(E) After the proper sizing is approved by town staff, the pre-cast unit can be purchased and installed at the owner’s expense.
(F) After installment, the plumbing should be inspected by the Plumbing Inspector.
(G) Equations from the EPA design manual On-site Treatment and Disposal Systems are used to check the adequacy of the proposed grease trap interceptor based on the size, location, and running time of the facility.
(Prior Code, § 51.27) Penalty, see § 10.99
