The City of Lexington Stormwater Management Program recommends that storm drain inlet protection be used when there is the potential for sediment-laden stormwater runoff and/or un-permitted non-stormwater discharges that could enter a drain inlet while conducting maintenance activities. This bulletin reviews procedures for properly protecting storm drain inlets so that pollutants related to maintenance activities are not discharged to the storm drainage system.

Storm Drain Inlet Protection (cont.)
Gutter Guards
Big Reds
Fiber Roll
Sand Bag
Gravel/Rock Bag
Sandbags promote ponding of water and settlement of sediment, where gutter guards, fiber rolls and gravel bag barriers tend to filter sediment while allowing for flow of water through the BMP, thus reducing the potential for ponding. Also, try other new approved products as they become available to achieve the same goals of minimizing pollutants in the storm drainage system.
(2) Impermeable cover should be used to prevent un-permitted discharges from entering the stormwater drainage system during maintenance activities.

Think Public Safety First
Striking a balance between storm water pollution prevention and safety can be challenging. However, both goals can be achieved with proper planning and implementation of appropriate BMPs. Drain inlet protection can potentially impact safety in three ways: (1) BMPs may cause excessive ponding of water in traffic lanes, (2) BMPs may impact the normal flow of traffic, and (3) installing and maintaining BMP in traffic lanes may jeopardize the safety of maintenance personnel.
Think Public Safety First! Minimize incidents and do not compromise safety in order to install or maintain water pollution controls.

Storm Drain Inlet Protection

Storm Drain Inlet Protection
Storm drain inlet protection may be needed during a number of different maintenance activities, including:
Asphalt rehab and paving
Concrete paving and repair (including saw cutting)
Graffiti removal
Landscape maintenance
Paint striping and marking
Vehicles and equipment repair and fueling
Grinding operations
Depending on the maintenance activity and the location, inlet protection practices may be used in two ways: (1) to detain and/or filter sediment-laden stormwater runoff and (2) to prevent un-permitted non-stormwater discharges from entering the stormwater drainage system.
(1) Storm drain inlets should be protected during maintenance activities to filter sediment-laden stormwater runoff by surrounding the inlet with one or a combination of the following temporary control measures:

Last Line of Defense
Storm drain inlet protection is the last line of defense to prevent sediment and other pollutants for discharges. Source control BMPs should be implemented at the activity site, upgradient of inlets, to minimize storm water from transporting sediment and/or other pollutants to the storm drain inlet.
Cleanup and Disposal
When work is completed, it is the responsibility of the maintenance crew to pickup BMP materials and any accumulated sediment, debris, and/or thrash within the area of the protected inlets. Store reusable BMPs and properly dispose of any accumulations.

If your newsletter is folded and mailed, this story will appear on the back. So, it’s a good idea to make it easy to read at a glance.
A question and answer session is a good way to quickly capture the attention of readers. You can either compile questions that you’ve received since the last edition or you can summarize some generic questions that are frequently asked about your organization.
A listing of names and titles of managers in your organization is a good way to give your newsletter a personal touch. If your organization is small, you may want to list the names of all employees.
If you have any prices of standard products or services, you can include a listing of those here. You may want to refer your readers to any other forms of communication that you’ve created for your organization.
You can also use this space to remind readers to mark their calendars for a regular event, such as a breakfast meeting for vendors every third Tuesday of the month, or a biannual charity auction.
If space is available, this is a good place to insert a clip art image or some other graphic.
