Spartanburg Waters Grease Control Program

1. Using water with a temperature higher than 140 degrees F can dissolve grease causing it to possibly pass through the grease trap allowing the grease to solidify downstream of the grease trap in the sanitary sewer system 17 Recycle waste cooking oil Staff should place waste oil from fryers and any other used fats oils and greases in waste oil recycling bin on site for offsite disposal Most recyclers will provide outside receptacles for storage until pickup Vehicular maintenance shops should also recycle any waste motor oil that may be recovered from servicing vehicles It is recommended that the owner user or business manager inspect the cleaning of the grease traps or oil water separators to ensure that the trap or separator is properly pumped Maintenance of under the counter and in ground outside grease traps All under the counter grease traps must be cleaned weekly All in ground outside grease traps must be pumped once per quarter These maintenance schedules may be altered if necessary We recommend that pumping events be witnessed to ensure that proper pumping is occurring in accordance with the Spartanburg Water Grease Program policy Keep a maintenance log Maintain a log on when fryers are cleaned and the volume of oil removed and placed into the recycling bins A record should also be maintained on when and how an outside grease trap is pumped These records must be available and accessible on site for review for a2. collection system or at the District s facilities that the District deems necessary to investigate or identify the user as the source of a pollutant 2 District personnel time and materials used in conducting any monitoring or investigation that the District deems necessary to the enforcement action in issuing correspondence or orders pertaining to the enforcement action or in any remedial efforts which the District deems necessary to mitigate or correct the impact on any District facilities or processes of a user s violation s 3 outside laboratories or consultants utilized by the District in the investigation or in any remedial efforts which the District deems necessary to mitigate or correct the impact on any District facilities or processes of a user s violation s and 4 any fines or penalties imposed on the District as the result of violation of any NPDES or other permit condition any state or federal regulation or any law any attorneys fees incurred by the District in connection with a violation of the Rules and Regulations Billing for analyses performed by the District shall be in accordance with the current charges adopted by the Commission Billing for District personnel time shall be time at the employee s current rate of pay plus benefits Billing for the services of outside laboratories and consultants shall be the cost billed to the District plus necessary fees to recover the cost of handling and administration Bi
