§ 14-97. Grease control devices.

(a)

Requirements. .....All FSEs shall have a GCD(s) meeting all applicable requirements of the International Plumbing Code or its successors. The GCD(s) shall be designed in accordance with the Hampton Roads Regional Grease Control Device Design Standards.

(1)

New establishments. .....Except as provided in subdivision (a)(2), FSEs shall be required to install, operate, and maintain a GCD in compliance with the requirements contained in the article. GCDs shall be installed and registered prior to the issuance of a certificate of occupancy.

(2)

Existing establishments with GCDs. .....Existing FSEs in operation as of the effective date of this article shall be allowed to operate and maintain their existing GCDs, provided such GCDs are in proper operating condition and not found to be contributing FOG in quantities to cause line stoppages or to necessitate increased maintenance of the sanitary sewer system. If the FSE is determined to be contributing FOG in quantities to cause line stoppages or to necessitate increased maintenance of the sanitary sewer system, the existing FSE shall comply with the requirements of this section. Existing FSEs that are renovated or expanded shall install a GCD meeting the requirements of this article. GCDs shall be installed, inspected and registered as condition of final approval of such renovation or expansion.

(3)

Retrofit. .....Any existing FSE shall be required to install or upgrade a GCD if such FSE is contributing FOG to the sanitary sewer system, as determined by the county and HRSD. Such devices shall be registered with the county within thirty days of installation.

(b)

Installation of grease control devices. .....GCDs shall be installed by a plumber licensed in the Commonwealth of Virginia. Every GCD shall be installed and connected so that it may be readily accessible for inspection, cleaning, and removal of the intercepted food waste and grease at any time.

(c)

Maintenance of grease control devices.

(1)

All GCDs shall be maintained at the owner's expense. Maintenance shall include the complete removal of all contents, including floating material, wastewater and settled solids. Decanting or discharging of removed waste back into the grease interceptor or private sewer line or into any portion of the county's or HRSD's sanitary sewer system is prohibited.

(2)

Grease interceptors shall be pumped out completely when the total accumulation of FOG, including floating solids and settled solids, reaches twenty-five percent of the overall liquid volume. At no time shall a GCD be cleaned less frequently than once every three months unless allowed by the director of general services or his designee for good cause shown. Approval will be granted on a case-by-case basis upon submittal of a request by the FSE, documenting reasons for the proposed frequency variance.

(3)

Grease traps and grease removal devices shall be opened, inspected and completely cleaned of food solids and FOG a minimum of once per week, unless allowed by the director of general services or his designee for good cause shown. Approval will be granted on a case-by-case basis upon submittal of a request by the FSE documenting reasons for the proposed frequency variance. In no event shall the content of food solids and FOG exceed twenty-five percent of the overall liquid depth of the device.

(4)

The director of general services or his designee may establish a more frequent cleaning schedule if the FSE is found to be contributing FOG in quantities sufficient to cause line stoppages or to necessitate increased maintenance of the sanitary sewer system.

(d)

Use of additives. .....The use of additives by FSEs including, but not limited to, products that contain solvents, emulsifiers, surfactants, caustics, acids, enzymes or bacteria are prohibited for use as grease management control; provided, however, that additives may be used to clean the FSE drain lines so long as the usage of such additives will not cause FOG to be discharged from the grease control device to the sanitary sewer system. The use of additives shall not be substituted for the maintenance procedures required by this section.

(e)

Waste disposal.

(1)

Waste removed from a grease trap shall be disposed of in the solid waste disposal system or by a grease hauler certified by the Hampton Roads Planning District Commission.

(2)

Waste removed from a grease interceptor shall be disposed of at a facility permitted to receive such wastes. No materials removed from interceptors shall be returned to any grease interceptor, private sewer line or into any portion of the county's or HRSD's sanitary sewer system.

(3)

FSEs shall dispose of yellow grease in a render able FOG container, where contents will not be discharged to the environment. Yellow grease shall not be poured or discharged into the county's or HRSD's sanitary sewer system.

(f)

Inspection of grease control devices. .....The director of general services or his/her designee shall have the right of entry into any FSE, during reasonable hours, for the purpose of making inspections, observation, measurements, sampling, testing or records review of the sanitary sewer system and GCDs installed in such building or premises to ensure that the FSE is in compliance with this article. The owner or occupant may accompany the director or his designee. Operational changes, maintenance and repairs required by the director or his designee shall be implemented as noted in the written notice received by the FSE.

(g)

Recordkeeping.

(1)

FSEs shall retain and make available for inspection and copying records of all cleaning and maintenance for the previous three years for all GCDs. Cleaning and maintenance records shall include, at a minimum, the dates of cleaning/maintenance records, the names and business addresses of the company or person performing each cleaning/maintenance and the volume of waste removed in each cleaning. Such records shall be kept on site and shall be made immediately available to any employee of Isle of Wight General Services upon request.

(2)

FSEs shall retain and make available for inspection and copying records of yellow grease disposal for the previous three years. Yellow grease disposal logs shall include, at a minimum, the dates of disposal, name and business address of the company or person performing the disposal and the volume of yellow grease removed in each cleaning. Such records shall be kept on site and shall be made immediately available to any employee of Isle of Wight General Services upon request. (Ord. No. 2011-2-C, 1-6-11.)
