Maintenance requirements for best management practices

A. Routine maintenance and repair procedures.
- (1) Preventative maintenance procedures are required to maintain the intended operation and safe condition of the stormwater management facility by greatly reducing the occurrence of problems and malfunctions. To be effective, preventative maintenance shall be performed on a regular basis and include such routine procedures as training of staff, periodic inspections, grass cutting, elimination of mosquito breeding habitats, and pond maintenance. Disposal of sediment and debris must occur on a regular basis (unless otherwise specified within an approved plan), at suitable disposal sites or recycling sites and comply with applicable local, state and federal regulations.
- (2) Corrective maintenance procedures are required to correct a problem or malfunction at a stormwater management facility and to restore the facility's intended operation and safe condition. Based upon the severity of the problem, corrective maintenance must be performed on an as-needed or emergency basis and include such procedures as structural repairs, removal of debris, sediment and trash removal which threaten discharge capacity, erosion repair, snow and ice removal, fence repair, mosquito extermination, and restoration of vegetated and nonvegetated linings.
B. General maintenance standards.
- (1) Maintenance design and maintenance procedures for all stormwater best management practices shall be in accordance with the Rhode Island Stormwater Design and Installation Standards Manual, as amended; or the Rhode Island Soil Erosion and Sediment Control Handbook, as amended. Stormwater management plans shall demonstrate appropriate maintenance design and procedures for each proposed best management practice.
- (2) A maintenance schedule for each type of BMP must be included in the stormwater management plan. These schedules shall list the frequency and type of maintenance operations necessary along with the legally responsible party’s name, address, and telephone number. If the stormwater drainage system is to be deeded to the local municipality, the applicant must obtain a letter from the municipality acknowledging maintenance responsibility and intent of ownership.
