Construction activities – which include remodeling, repairs and demolition – can generate a wide variety of contaminants that can pollute stormwater including sediment and suspended solids, solvents, paints, cleaners, adhesives, wood treatments, heavy metals, and asphalt and concrete, as well as trash and debris.
- By implementing the procedures below during all construction, remodeling, repair and demolition activities, your business and project site can be part of the solution to stormwater pollution.
- Keep the construction project site clean and orderly. Sweep outdoor areas regularly and do not hose down to stormwater drains, drainage ditches or surface waters.
- Use stormwater drain covers, filter fabric, silt fences, or secured liners to keep dust, sediment, other pollutants and wash water from entering the stormwater drainage system.
- Store all construction materials indoors, or under a secure waterproof tarp or cover, wherever possible.
- Do not dump any solid or liquid waste materials onto the ground or pavement, down a stormwater drain, or into a drainage ditch or surface water.
- Contact utilities protection center(s) and coordinate with Austell Public Works prior to digging. Look for manholes and clean-outs that may indicate the presence of sewer or septic systems.
- Follow the approved Erosion, Sedimentation, and Pollution Control Plan and implement appropriate erosion, sediment, and pollution controls and best management practices.
- Follow established best practices and procedures for concrete and asphalt installation, landscaping, and fueling activities.
- Heavy equipment, pumps, and generators should be properly maintained, so they do not leak petroleum, hydraulic oil, or other pollutants.
- Remove debris and trash in a timely fashion. Properly dispose of construction debris and waste materials, including sweepings, sediment and washwater. Recycle residual building materials and supplies to the maximum extent practicable.
- For demolition activities, use water spray or approved dust suppressants to help control dust and particulates. The amount of water should be actively controlled and monitored to eliminate contaminated runoff from leaving the site. Avoid excessive and repeated applications of dust suppressant chemicals.
