LONG TERM STORMWATER
OPERATION & MAINTENANCE PLAN
Stormwater management system owner: Global Companies
LLC
The party or parties responsible for operation and maintenance: Global Companies,
LLC
The owner of the system shall be the landowner of the property. The Order of Conditions
and Certificate of Compliance should be written to allow for routine maintenance during
construction and post-development phases of the project as defined in the O&M Plan.A
continuing condition in the Certificate of Compliance will ensure that maintenance can be
performed without triggering further filings under the Wetlands Protection Act.
Construction Phase Operation and Maintenance
1. Temporary erosion control measures will be inspected daily and repaired and
or replaced as necessary. As catch basins are made able to accept stormwater
runoff a silt sack® shall be installed.
2. Catch basins will be inspected weekly and cleaned as necessary. Silt Sacks®
shall be removed, cleaned and replaced as necessary.
3. Paved areas will be swept as needed and accumulations of sand/silt due to
construction activities shall be removed as soon as the activity is terminated.
4. Oil/Gas Sediment Separator(once installed)shall be inspected weekly and
just after a significant rain event and maintained as described in the Final Site
Operation and Maintenance Plan.
5. The owner shall keep a log of operations during the construction phase. This
log will be used in further defining the Final Site Operation and Maintenance
Plan.
Street Sweeping
Street sweeping efforts shall be performed twice annually once during the late spring, the
period immediately following winter snowmelt, when road sand and other accumulated
sediment, and once in early fall seasons.
Stormceptor Unit (Information gathered at Stormceptor.com)
Maintenance Procedures General
Stormceptor®should be inspected and maintained regularly. Stormceptor®units should
be inspected every six months and cleaned when the sediment level reaches 15%of total
storage volume. Refer to Stormceptor®Procedures for details. If regular inspections are
not conducted, Stormceptor®units should be cleaned once a year. Stormceptor®units
should also be inspected following a spill event. All oil captured by the Stormceptor®
should be removed. Inspection and maintainence should be part of the Standard
Operating Procedure.
Safety
Do not enter the Stormceptor®treatment chamber unless properly trained, equipped and
qualified to enter a confined space as identified by local Occupational Safety and Health
Regulations. Watch for and avoid contact with overhead power lines when inspecting the
unit with long sampling devices(e.g. Sludge Judge®) Stormceptoro is designed so
inspection of the unit can be preformed from grade(i.e. inspect for obstructions, etc.)
Qualified personal may enter the upper by-pass chamber and use the insert as a platform
to remove obstructions, sewer flushes, or camera surveys. Be aware that the insert may be
slippery. Be aware that some units do not have a safety grate over the outlet riser pipe.
Procedure
Maintenance is performed using a vacuum truck. A catch basin vacuum truck is not
recommended for maintenance.Remove cover from unit from grade,lower hose through
by-pass chamber and into treatment chamber. Vacuum trucks are able to remove material
from a maximum distance of 32 feet below grade; additional charges may apply if
installation is deeper.
Roof Drain Infiltration Areas
The infiltration drywell and trench shall be inspected after every major storm in the first
few months after construction to ensure proper stabilization and function. Thereafter,the
system shall be inspected once per year. Water depth in the observation ports should be
measured at 0,24 and 48-hour intervals after a storm. Clearance rates are calculated by
dividing the drop in water level (inches)by the elapsed time(hr). The clearance rates
shall be logged and compared from year to year. The system should fully drain within 72
hours of the storm.
