Frequently Asked Questions:
Who needs a land disturbance permit?
Regulations can vary depending on locality, but in general anyone who is planning to disturb more than one acre of land is required to obtain a land disturbance permit from their local issuing authority and submit a notice of intent for coverage under the applicable NPDES General Permit.
Are there any exceptions?
Some activities are exempt from needing a land disturbance permit such as:
- Minor land disturbances (such as gardening and landscaping)
- Construction of single-family homes (provided that the disturbed area is less than one acre and the home is not part of a common development)
- Any other project with less than one acre of disturbed area (provided that the disturbance is greater than 200 feet from state waters and is not part of a common development)
- Other activities such as surface mining, agriculture, and forestry
What does NPDES stand for?
NPDES stands for National Pollution Discharge Elimination System.
What is an NPDES permit?
The Clean Water Act (CWA) prohibits anybody from discharging pollutants into a water of the United States unless they have an NPDES permit. This includes everything from industrial wastewater to storm water runoff from construction sites. To simplify the permitting process for some categories of users, a series of general permits has been developed.
What does an NPDES permit for construction activities require?
Among other things, the general permit for construction activities requires the permittee to complete these actions:
- Develop and follow an Erosion, Sedimentation, and Pollution Control Plan (ESPCP)
- Install and maintain structural best management practices (BMPs) to limit the migration of sediment from the project area
- Conduct inspections of the BMPs and project area according to a set schedule
- Collect samples of stormwater where it runs off the project area and analyze the turbidity to demonstrate compliance with the permit
- Maintain records of daily rainfall amounts, inspection reports, turbidity measurements, and all other documentation related to the permit
How do you apply for an NPDES permit?
To obtain coverage under a general NPDES permit, a Notice of Intent (NOI) form must be completed and submitted to your state's Environmental Protection Agency.
How often are NPDES inspections required?
The terms of the NPDES permit require the following inspections to be performed by certified Level I-A personnel:
- Daily inspections of vehicle entrances and areas where petroleum products are stored, used, or handled
- Weekly inspections of all areas of the project that have not undergone final stabilization (these areas must also be inspected within 24-hours of a rainfall of 0.5-inch or greater)
- Monthly inspections of all areas of the project that have undergone final stabilization
How often are stormwater samples required?
Stormwater monitoring is an important task and sampling is required a minimum of twice during the life of the project; however, if the samples fail to meet the site-specific turbidity requirements, additional sampling is required.
