The Construction Manager’s Guide to SWPPP Inspections

Drafting a stormwater management plan requires tons of planning and investment, but many construction managers are shocked to learn how big of a commitment it really is. 

Between varying weather patterns, equipment ware, and new solutions needed on the fly, stormwater management can turn out to be a real financial headache. 

One way to mitigate and correct issues early is to perform frequent inspections to identify issues before they spiral out of control.

Far from hindering progress, SWPPP inspections come with several benefits for site managers. This guide will discuss everything you need to know about SWPPP inspections, including who performs them, how often, and tips to optimize your operational efficiency. 

Benefits of SWPPP Inspections

SWPPP inspections are vital for the health and environmental safety of any construction project. 

While they are required by the EPA, they also yield several benefits to construction managers that may be overlooked.

  • Identify Issues Early in Projects: An SWPPP inspection will identify any BMPs that require replacement or are not working efficiently enough. This will save you headaches down the road from potential issues that can lead to increased costs via site restoration and fines. 
  • Ensure Regulatory Compliance: Inspections by a third-party inspector ensure you properly adhere to all NPDES and EPA requirements. 
  • Promote Long-Term Sustainability: SWPPP inspections help increase the efficiency of your operation, allowing you to avoid costly mistakes and maintain the integrity of your worksite. 

How Often Are SWPPP Inspections Required?

Inspection frequency varies by state, but the EPA recommends most inspections take place every 7-14 days or after a rain event of 0.25 inches or more. Inspections can occur more frequently depending on the type of site activity and its proximity to public water sources. 

Who Conducts an SWPPP Inspection?

Depending on your state, SWPPP inspections may be performed by a qualified inspector with formal certification or not. We recommend working with an accredited environmental consultant knowledgeable in stormwater management to perform your inspections. 

All inspections will be recorded within your SWPPP and submitted to the proper permitting authority at the end of the project. 

Elements of an SWPPP Inspection

Understanding the basic elements of a SWPPP inspection will help you prepare for your first one.

  • Site Assessment: SWPPP inspections start with a thorough site inspection to determine the state of worksites, any potential sources of pollution, and areas of vulnerability.
  • Weather Assessment & Rainfall Totals: An inspector will mark any rainfall totals and assess whether corrective actions should be taken to combat increased rainfall. 
  • List of Corrective Actions: An inspector will create a list of corrective actions to solve any stormwater management issues you may be having. 
  • Sediment and Erosion Control BMP Check: Inspectors will monitor the health and condition of your BMPs and determine if any changes need to be made.
  • Water Quality: Local water samples may be taken to determine if any pollutants from your worksite have leaked into the water. 
  • Documentation and Record Keeping: Inspectors will audit all documentation and record keeping to ensure proper regulatory compliance.
  • Training and Education Programs: A brief audit of all training programs and materials used for employees and contractors will be noted.
  • Regulatory Compliance: Inspectors will mark down any other issues your worksite might be having that could be in violation of federal or municipal guidelines. 

Tips for Conducting Effective SWPPP Inspections

To make the most of SWPPP inspections, consider the following:

1. Schedule Regular Inspections

Plan weekly inspections to ensure proper site safety and to identify any other opportunities for improvement. We always recommend a thorough inspection after a significant rain or snow event has occurred. 

2. Document Findings

Record any issues your worksite is experiencing for future use. You may find inspiration from those notes when you encounter the same problems again.

3. Follow Inspector Recommendations

Most inspectors are highly knowledgeable in environmental issues that pertain to stormwater management. Therefore, they will offer the best advice to optimize your SWPPP and correct any issues. 

4. Train Staff

Train staff on proper SWPPP compliance and work with an inspector to draft new training materials for any recommendations they put forth.

FAQs: Stormwater Inspections

Who is responsible for SWPPP compliance?

SWPPP compliance is managed by the construction site manager but should be practiced by all personnel, including subcontractors. 

How often should SWPPP inspections be conducted?

Site inspections should be performed every seven days or after a major rainfall event. This ensures that no potential runoff or flooding issues arise. 

Can SWPPP inspections be unannounced?

Yes, SWPPP inspections can be unannounced. In fact, surprise inspections are often more effective at assessing compliance because they prevent sites from preparing or making temporary changes to pass the inspection.

What are the potential penalties for SWPPP violations?

Penalties for SWPPP violations can range from fines to stop-work orders, and they can vary depending on the severity of the violation and local regulations. Frequent violations may lead to more stringent penalties and legal consequences.
