 |
|
are an effective means to filter stormwater. They are held in place by the
metal grate that covers a catch basin and removes metal filings, oils/hydrocarbons and sediment as they
flow into the basin. Catch Basin Filters can be used in a catch basin that is adjacent to the roll-off bin and
act as a primary or secondary means of capturing pollutants that flow out of the roll-off bin.
Considerations include:
? Selective filter media may be inserted; it must match the specifications of the pollutants at
the site.
? Regular maintenance is especially important because the discharge from the device is not
usually visible. They can be fitted with maintenance alarms.
While structural controls prevent and control storm water pollution, the Industrial Storm Water Permit
requires their use when nonstructural controls are inadequate in preventing contamination of storm
water. So, structural controls such as oil and water separators can not be the primary treatment devices
under the Industrial Storm Water Permit.
