Precipitation from melted snow and rain generates storm water runoff which flows down the land or impervious surfaces without percolating in the ground. As this water flows over land and surfaces like parking lots, paved streets, and building rooftops, it collects elements on its way like chemicals, debris, sediments and other pollutants which have an adverse effect on the quality of the water in case this runoff is discharged without treating it.

The basic method of controlling this storm water discharge is by sticking to best management practices. Apart from that, most storm water discharges are considered as point sources and need coverage under National Pollutant Discharge Elimination System permit. Getting this permit is important for various departments and professionals like project managers, engineers, government officials, construction managers, public works and utilities directors, as well as environmental professionals.

With authorization from the Clean Water Act, NPDES permit program is required to control water pollution by regulation of those point sources which discharge pollutants in the water sources in U.S. Discrete conveyances like man made ditches and pipes can be referred to as point sources. Individual homes which are connected to the municipal system or make use of any special system don’t require NPDES permit of this sort. Also, the homes which do not lead to any surface discharge are free from obtaining this kind of permit. However, municipal, industrial, as well as some other facilities, are required to obtain such permits in case their discharges head towards surface waters.

NPDES Regularity Compliance

The EPA inspects various facilities for compliance that are subject to regulations. EPA's inspections include:

  • Reviewing the discharge monitoring reports of the facilities
  • Interviewing personnel from the facilities that look into this matter
  • Inspecting all the processes which generate as well as treat waste water
  • Sampling discharges of the waste water to navigate waterways as well as other points in the treatment or generation process
  • Reviewing the process of collecting samples by the facility and checking how the samples are analyzed in the laboratories

Storm Water Pollution Prevention Plan (SWPPP) is required under NPDES for regulating the quality of water in association with industrial or construction activities. This plan addresses all the pollutants, as well as their sources, which also include sediments linked with construction, erosion of the construction site and other related activities. 

Developing an Effective SWPPP

If you are looking to develop an effective storm water pollution protection plan for your industrial or construction project, you need to work in accordance with the Construction General Permit (CGP) that came into effect in September of 2011. According to this permit, all SWPPPs need to be certified as well as prepared by a SWPPP developer who is qualified to do the job. Your project should also pass the risk level determination test done under CGP. It is also necessary for the project to go through inspection to ensure that best management practices are being followed. If your project has a risk level of two or three, you will need to prepare it for the Rain Event Action Plans accordingly.
