STORMWATER MANAGEMENT SYSTEM
OPERATION &MAINTENANCE PLAN
This Stormwater Management System Operations & Maintenance Plan (the Plan) outlines measures that are
essential for maintaining an effective stormwater management system at the Rea's Pond Pumping Station located on
Great Pond Road, North Andover, Massachusetts (the Site). Periodic and scheduled inspections and maintenance
measures are recommended to prevent deficiencies and for proper performance of the stormwater management
system. Failure to implement these measures can reduce the hydraulic capacity and the pollutant removal efficiency
of stormwater measures resulting in a poor quality of stomiwater runoff discharging from the Site.
RESPONSIBLE PARTY&ESTIMATED ANNUAL BUDGET
The party responsible for implementing this Plan and identifying the source of necessary funds is as follows:
Division of Public Works
384 Osgood St.
North Andover,MA 01845
(978)685-0950
The estimated annual budget for implementing this Plan is$750.00.
INSPECTIONS&MAINTENANCE MEASURES
The stormwater management system at the Site comprises of an inlet forebay, a proprietary separator catch basin
and subsurface infiltration units.The inlet forebay will collect sheet flow from the driveway surface and will serve as a
debris catchment prior to entering the proprietary separator. The proprietary separator will separate oil, grease and
sediments prior to discharging to the infiltration devices. The infiltration devices recharge the stormwater into crushed
stone beds. In the event of a 100-year storm event, the infiltration devices will overflow through an orifice and
discharge to a gravel-filled level spreader.Measures are illustrated on the Stormwater Management System figure in
Attachment A.
}
An Inspection Form is provided in Attachment B that is recommended for use during inspections of the stormwater
management system. The form includes a table that outlines specific inspection and maintenance measures, in
addition to the following information that can be updated by the inspector during the inspection:
• Name of inspector
• Name of the site and its location
• Date and time of inspection
• Weather conditions during inspection
• Outline of items inspected
• Condition of the stormwater management system, including corrective measures taken to maintain the
system
Completed Inspections Forms should be kept at the Site to enable both facility managers and regulatory agencies to
ensure that operation of the system is in compliance with permit requirements.
