FEDERAL, STATE,
AND LOCAL ORDINANCES
REQUIRE PROTECTIVE MEASURES
Carboro's storm drainage system is designed to
collect stormwater from rain events and ultimately
convey this runoff into the streams, creeks and rivers
surrounding the Town. If not treated properly, runoff
can carry slurry from directional borings into storm
drains and then directly into the receiving water
bodies. Directional boring fluids can contain
potential contaminants such as hydrocarbons, heavy
metals, as well as solids.
Care must be taken to ensure that stormwater run off
does not harm the quality of our surrounding waters.
A list of potential Best Management Practices
(BMPs) applicable to your business is provided.
Implementing these BMPs and practicing good
housekeeping will help guarantee a safe working
environment and clean water.
Carrboro's Town Code prohibits the
discharge of non-stormwater, chemicals,
and materials into the storm drainage
system
BEST
MANAGEMENT
1. LOCATE INLET POINTS: Locate all nearby storm
drain inlets, catch basins, culverts or swales through
which boring mud may enter a waterway. If feasible,
pump water through a grassy swale prior to discharge.
Block the path to the nearest drain and either divert mud
flows or block inlets to pool water away from drains. If
another utility is compromised, immediately reinforce
protection and contact local authorities.
2. MINIMIZE SLURRY FLOWS: Slurry and sediment
from boring operations or saw cutting must be confined to
the immediate work area by using temporary berms, sand
bags or diversion structures. Prevent cars and
pedestrians from tracking of slurry off -site.
3. REMOVE SLURRY: Remove ALL slurry and runoff
from the boring operation as soon as possible. Remove
any slurry collected near storm drain inlets by pumping it
into a collection vessel or using a wet/dry vacuum. Slurry
entering the drainage system MUST be removed
immediately.
4. TRAIN EMPLOYEES: Train your employees to
use proper BMPs
