Developers, contractors, and persons disturbing one acre or more of land need to obtain stormwater general permit coverage before any work begins. A copy of their Waste Discharge Identification Number (WDID) will need to be on file with the City of Patterson.
The following is a list of construction materials that may be used, and activities that may be performed, that will have the potential to contribute pollutants, other than sediment, to stormwater runoff.
The contractor shall, at all times, keep property on which work is in progress, and the adjacent property, free from the accumulation of waste material or rubbish caused by employees or the work.
