Elevate your SWPPP inspection game with our definitive guide. Learn the essentials for robust stormwater pollution prevention planning.

Last Updated on May 12, 2024 by Ossian Muscad

Construction projects can cause a lot of environmental damage if not done properly. If your company is planning a construction project, you must have a plan to deal with the stormwater runoff. This is where a Stormwater Pollution Prevention Plan comes in handy. This article will discuss what a SWPPP inspection is and how you should use it to ensure that your construction project stays environmentally friendly.


What is SWPPP Inspection?

Stormwater pollution prevention plans (SWPPP) are a set of steps that should be taken to minimize the pollution caused by construction projects. SWPPP inspections are conducted to verify that the steps in the stormwater pollution prevention plan are followed correctly. A qualified professional, such as an environmental consultant, should conduct the inspection.


What is a SWPPP Checklist?

An SWPPP checklist is a document that lists best practices for minimizing pollution during a construction project. It should be in compliance with the Clean Water Act of 1972 and any other state or local regulations and customized to the specific project site. With an SWPPP checklist, you can be sure that your construction project follows all the necessary steps to prevent pollution.


Why Is an SWPPP Inspection Important?

SWPPP inspections are important because they ensure that the stormwater pollution prevention plan is followed correctly. If the plan is not followed, it could lead to environmental damage. Therefore, the inspection should be conducted regularly to ensure the plan is followed correctly. Stormwater pollution prevention plans are important for construction projects. With an SWPPP checklist, you can be sure that your construction project follows all the necessary steps to prevent pollution.


Common Stormwater Inspection Issues

There are a few common problems that can occur during a stormwater inspection. Here are some of the most common problems, along with how to solve them:


Heavy rains or storms can cause erosion, which can damage the construction site and pollute the air. To prevent this, you should have a plan to control erosion. This may include using sediment fences or other methods to keep soil in place.


Runoff is water that flows over the land surface after precipitation. This water can pick up pollutants and carry them into nearby waterways. To prevent this, you should have a plan to control runoff. This may include using sediment basins or other methods to prevent water from flowing over the land.


Sedimentation is the deposition of sediment in waterways. It can be caused by erosion or runoff. To prevent sedimentation, you should have a plan to control it. This may include using sediment fences or other methods to keep sediment out of waterways.

Improper Waste Disposal

If construction waste is not properly disposed of, it can also enter the stormwater system and cause damage. To solve this problem, you must ensure that all construction waste is properly disposed of in dumpsters or landfills. You should also have a plan in place for dealing with hazardous waste.

Missing Temporary or Permanent Cover

Any construction activity that has disturbed the ground must be covered with either temporary or permanent cover. This will prevent sediments from being eroded by rain or wind and entering the stormwater system. You must install the appropriate cover for the disturbed area to solve this problem.

To solve this compliance problem, you’ll need to incorporate and maintain the following best management practices:

Temporary ‘Best Management Practices (BMP)’:

  • Mulches
  • Temporary seeding
  • Blankets and mats
  • Matrices
  • Soil binders

Permanent BMPs:

  • Sodding
  • Permanent seeding and planting
  • Vegetative buffer strips
  • Channel stabilization

No Inlet Protection

Before starting a construction project, every storm inlet that receives a discharge from the site needs protection and maintenance until the site is stabilized. Inlet protection may be removed when management detects safety issues. In addition, the SWPP should also document written correspondence between the project manager and local authorities regarding the status of inlet protection.

To solve this problem, you’ll need to install inlet protection devices such as:

  • Grate inlet protection devices
  • Curb inlet protection devices
  • Sediment control bags or baskets
  • Vegetative filter strips


SWPPPs and Corrective Action Solutions to Promote BMPs

If any of the above problems are found during a stormwater inspection, you’ll need to take corrective action to promote best management practices (BMPs). Some corrective action measures may include: 

Develop and Implement a SWPPP

If you don’t already have one, you’ll need to develop and implement a stormwater pollution prevention plan (SWPPP). This will help you identify potential pollution sources and implement preventive measures.

Educate Employees

You’ll need to educate your employees on the importance of following best management practices. This will help to ensure that they are properly trained and aware of the steps they need to take to prevent pollution.

Monitor the Site

You’ll need to monitor the site regularly to ensure that best management practices are followed. This will help you identify potential problems and correct them before they cause environmental damage.

Create a Maintenance Plan

You’ll need to create a maintenance plan to ensure that all stormwater control measures are properly maintained. A maintenance plan will help ensure that the control measures are effective and continue to meet the site’s needs.

Take Corrective Action

If you find that best management practices are not followed, you’ll need to take corrective action. This may include retraining employees, repairing damage, or taking disciplinary action.


Frequently Asked Questions (FAQs)

Q1: How often should SWPPP inspections be conducted?

The frequency of SWPPP inspections typically depends on the requirements set by local regulations. However, it is common practice to conduct inspections at least once every seven days and after any storm event that results in 0.25 inches of rain or more within 24 hours.

Q2: Who is qualified to perform SWPPP inspections?

SWPPP inspections should be performed by individuals who are knowledgeable about the stormwater pollution prevention plan and its implementation. This usually means someone who has been trained in identifying potential pollutants and understanding the best management practices laid out in the SWPPP.

Q3: What should be done if an inspection reveals non-compliance with the SWPPP?

A3: If an inspection reveals any non-compliance with the SWPPP, corrective actions should be initiated immediately to address and rectify the issues. A documented plan of the corrective actions, including timelines for their completion, should be added to the SWPPP documentation.

Q4: Can the SWPPP be modified during the construction project, and how?

Yes, the SWPPP can be modified during the construction project. Modifications may be necessary due to changes in construction plans, unforeseen environmental conditions, or after identifying inefficiencies in the current plan. Any modifications should be documented, including the rationale for the change and the expected environmental impact.

Q5: How long must SWPPP documents and inspection reports be retained after project completion?

The retention period for SWPPP documents and inspection reports varies by jurisdiction but is typically for a minimum of three years after the completion of the project. This allows regulatory agencies to review the documents if necessary and ensures accountability.

Q6: How does weather impact SWPPP implementation?

Weather significantly impacts SWPPP implementation, particularly in terms of managing runoff and erosion. Best practices in response to weather changes include:

  • Adjusting inspection schedules around heavy rain events.
  • Reinforcing sediment and erosion controls before storms.
  • Ensuring that stabilization measures are in place for inactive sites during wet seasons.
