not delay the removal of trash, debris, and sediment. Temporary disposal sites should be utilized if necessary. b) Structural Repairs: Structural damage to outlet and inlet structures, trash racks, access hatches, roadways and walls as a result of vandalism, flood events, settlement, or other causes must be repaired promptly. The urgency of the repairs will depend upon the nature of the damage and its effects on the safety and operation of the facility. The analysis of structural damage and the design and performance of structural repairs should only be undertaken by the consulting Professional Engineer. c) Extermination of Mosquitoes: If neglected, basins can become an ideal mosquito breeding area. The extermination of mosquitoes will usually require the services of the County Mosquito Commission. If mosquito control in the facility becomes necessary, the preventative maintenance program should be re-evaluated, and more emphasis should be placed on control of mosquito breeding habitats. d) Snow and Ice Removal: Accumulations of snow and ice can threaten the functioning of the inlets and outlets. Provision of the equipment, material, and personnel to monitor and remove snow and ice from critical areas will ensure the function of the facility during the winter months. 3. Recording and Logging of all Maintenance Activities: The recording of all maintenance work and inspections provides valuable data on the facility’s condition. A review of this information will also help to establish more efficient and beneficial maintenance procedures and practices. All recorded information should be directed to the owner of the basin for review and subsequent follow-up on recommendations. Data obtained from informal inspections should be retained; however, this data does not have to be submitted to NJDEP. A copy of all records and logs of maintenance activities shall be submitted to the Township Engineer annually for review. 4.
