Editor's Note: So in original.
(3) 
Chemical toilet wastes;
(4) 
Pleasure boat wastes;
(5) 
Industrial wastes collected in containers or tanks;
(6)

(7) 
Any other material not classified as residential sewage, including chemicals and other materials stored on the premises of the user which might, directly or indirectly, enter the Village sewer, accidentally or otherwise.
V. 
Any prohibited discharges per MMSD rules.
A. 
Grease control requirement. It is prohibited to discharge fats, oils, and grease (FOG) to the sanitary sewer system. Food service establishment owners and operators are required to control FOG discharge from their food service establishments to the sanitary sewer system and not cause or contribute to FOG-related sanitary sewer overflows (SSOs), blockages or increased maintenance to the sanitary sewer system.
B. 
Grease interceptor(s) shall be installed and maintained to prevent FOG-related SSO, blockages, or increased maintenance in the sanitary sewer system. Grease control devices are required if food service establishments meet any of the following conditions.
C. 
Approved grease control device.
(1) 
A grease interceptor device designed to intercept FOG from wastewater discharge shall be required. Grease interceptors include but are not limited to gravity grease interceptors and various other types of grease interceptors that require cleaning/servicing by a pumping company due to design or per manufacturer's specifications.
(2) 
On a case-by-case basis due to site practicality reasons, the Director of Building Services or Director of Public Works may allow an automatic grease removal device which is designed to retain FOG from wastewater discharge. An automatic grease removal device automatically removes FOG from the wastewater stream and transfers the FOG to an external container. Automatic grease removal devices are typically installed inside and aboveground and are generally cleaned by food facility staff.
D. 
Grease control device maintenance.
(1) 
If a food service establishment has one or more grease interceptors, they must be maintained as follows:
(a) 
By removing the entire contents of the interceptor each time the interceptor is pumped.
(b) 
To ensure proper operation, maintenance and performance during the entire period of wastewater discharge.
(c) 
A minimum pumping frequency of once per three month period, or more frequently if required to ensure that the food service establishment discharge does not cause or contribute to FOG-related overflows, blockages, or increased maintenance in the sanitary sewer system.
(2) 
If a food service establishment has one or more automatic grease removal devices, the device(s) must be operated and maintained according to manufacturer's specifications, including, but not limited to, maintaining appropriate power supply and emptying the FOG receptacle at the frequency described by the manufacturer in the owner's manual.
(3) 
More frequent maintenance and/or additional grease control device equipment may be required if a food service establishment continues to cause or contribute to FOG-related overflows, blockages, or increased maintenance in the sanitary sewer system.
(4) 
All employees shall be trained to properly maintain the grease interceptors and control devices in accordance with the maintenance requirements.
(5) 
Maintenance records. Food service establishments shall retain maintenance records. The maintenance records shall be kept a minimum of three years from the date of service and shall be provided to the Village on an annual basis. At minimum, the following information must be included:
(a) 
Grease interceptor: Monthly inspection, date of service; volume pumped (gallons); and waste disposal location.
(b) 
Automatic grease removal device: Date of grease receptacle emptying and/or maintenance; signature by staff conducting maintenance; waste disposal location.
(c) 
Employee training records as required by the Village.
A. 
National categorical pretreatment standards as promulgated by the U.S. EPA shall be met by all dischargers of the regulated industrial categories.
B. 
State requirements and limitations on discharges to MMSD water reclamation facilities shall be met by all dischargers which are subject to such standards in any instance in which are more stringent than federal requirements and limitation or those in this article or any other applicable ordinance.
C. 
MMSD requirements and limitations on discharges to MMSD water reclamation facilities shall be met by all dischargers.
D. 
The Village reserves the right to amend this article to provide for more stringent limitations or requirements on discharges to the MMSD water reclamation facilities.
E. 
Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction, to injure or interfere with any wastewater treatment process, to consist of a hazard to humans or animals, or to exceed the limitation set forth in state or federal categorical pretreatment standards is prohibited. A toxic pollutant shall include but not be limited to any pollutant identified in the Toxic Pollutant List set forth in Ch. NR 215, Wis. Adm. Code.
F. 
No discharger shall discharge wastewater containing concentrations (and/or mass limitations) above MMSD standards.
G. 
The use of diluting waters to meet the required standards for discharge of waste into the sewer is prohibited.
A. 
Each discharger shall provide protection from accidental sanitary sewer discharge of prohibited or regulated materials or substances established by this chapter. Where necessary, facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the discharger's cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the approving authority for review and shall be approved by the approving authority before construction of the facility. Review and approval of such plans and operating procedures by the approving authority shall not relieve the discharger from the responsibility to modify its facility as necessary to meet the requirements of this article.
B. 
Dischargers shall notify the approving authority immediately upon the occurrence of a slug load or accidental discharge of substances prohibited by this article. The notification shall include the location of discharge, date and time thereof, type of waste, concentration and volume, and corrective actions. Any discharger which discharges a slug load of prohibited materials shall be liable for any expense, loss or damage to the Village's sanitary sewer system or MMSD water reclamation facilities, in addition to the amount of any fines imposed on the approving authority on account thereof under state or federal law.
C. 
Signs shall be permanently posted in conspicuous places on the discharger's premises advising employees whom to call in the event of a slug or accidental discharge. Employers shall instruct all employees who may cause or discover such a discharge with respect to the emergency notification procedure.
A. 
Septic tanks are prohibited in the Village. The maintenance and use of septic tanks, holding tanks and other private wastewater disposal systems within the Village are declared a public nuisance and a health hazard.
B. 
Discharge of any septic tank contents into the Village sanitary sewer main is strictly prohibited.
