DOT Specifications for Turbidity Curtain

Customer Question About NYSDOT Silt Curtains

dot silt curtainsQuestion: We have been doing work in NY for a while and also do work in New Jersey. We are wondering why each state has its own DOT standards for silt barrier. Turbidity curtain appears pretty standard across the market, and it just seems that someone using turbidity barriers in Florida, Texas, or New York should all have the same basis for product use. We have seen the same in other BMP products like silt fence and geotextiles.

Surely if I am complying with the Clean Water Act and NPDES Phase II in one state, I can use the same NYSDOT silt curtains or other BMP products to comply in any other US state? I just figured someone out there will have the answer! Thank you.

In order to keep an eye on the way things are operating in each city, region, or state, there are local and state government agencies that create and enforce regulations and other requirements for stormwater pollution in their area. The standard regulations (NPDES, EPA, etc.) are in place to ensure that all states meet minimum requirements.

Each state has varying regulations depending on state laws, compliance requirements, and level of enforcement. There are ASTM committees to address DOT specifications, as well as other regulations, and various organizations that promote professional standards. Some associations include the International Geosynthetics Society, Industrial Fabrics Association, International Erosion Control Association, American Civil Engineering, and many others.

To understand the rules, become involved and continue to ask the type of questions that you are asking. National agencies often rely on state and local governments to help when implementing pollution requirements, such as DOT specifications, as a single national agency does not usually have the manpower to micromanage every individual city and county.

The system works and gets results. GEI Works looks at the bigger picture, so we comply to each state's DOT specifications and do our best to meet or exceed Federal Regulations.
