Operator Self-Inspections

What is the purpose of Operator self-inspections?

The purpose of the site self-inspections is to determine the functionality and effectiveness of the Best Management Practices (BMPs) controls and ensure no polluted stormwater or snow melt can leave the site.

Who is required to perform SWPPP inspections?

The Construction General Permit (CGP) requires the Operator (owner, contractor, or developer) to have qualified personnel conduct regular self-inspections. 

Does a SWPPP inspector need to be certified or specially qualified? 

Most states require that the Operator’s inspectors be "qualified personnel" with the knowledge and expertise to evaluate the site and BMP effectiveness. Some states mandate specialized certifications such as passing the EPA’s Stormwater Inspector Course,  Certified Erosion, Sediment, and Stormwater Inspector (CESSI) or Qualified Compliance Inspector of Stormwater (QCIS).

How often are SWPPP inspections required? 

Project BMPs are to be inspected at least every 7, 14, or 30 calendar days and within 24 hours after a qualifying rainfall event (e.g., 0.25 or 0.5 inches or more) as required in the SWPPP and Permit. Certain permits will have varying frequencies depending on proximity to sensitive water, site conditions, or violation history.

Which specific sections and BMPs must be inspected in a SWPPP inspection? 

Inspections are to include: 

• All disturbed areas of the site

• All erosion and sediment control BMPs (silt fence, storm drain controls, wattle, etc.)

• All non-stormwater pollution controls (concrete washout, fuel storage, trash bins, etc.)

• Discharge points. 

What is required to be noted in a SWPPP inspection? 

Inspection reports must include multiple details including:

• Date and time of inspection

• Inspector's name and title

• Weather conditions

• Description of inspected areas

• BMPs requiring repair or maintenance

• Any discharges of pollutants observed

• Planned or implemented corrective actions

What happens if deficiencies are noted during a SWPPP inspection? 

The Operator is obligated to take the required corrective actions as soon as possible (typically one business day) to alleviate any deficiency found during inspection. These are to be recorded in an action log, along with the completion date. Failure to make corrections may result in regulatory enforcement.

Where are SWPPP inspection records stored and for what duration? 

SWPPP inspection reports are typically required to be retained on-site, electronically, or easily available for inspection by the regulatory agency. Accena SWPPP Services  maintains all notes, action items, and an updated map in an online software program where you and the regulators will have instant access. 

How long do inspection records need to be stored?

The duration is specified in the state’s CGP. Typically, records need to be stored for three years from the date the permit has expired or been revoked.

Are there any checklists or forms that must be utilized for SWPPP inspections? 

Although some regulatory agencies often supply sample inspection checklists or forms, the CGP only specifies what information to record - not necessarily a specific form. Nevertheless, it is usually best practice to use a standard agency checklist, if one is available. 

How do SWPPP inspections and regulatory inspections differ?

Operator inspections are self-monitoring to ensure compliance and are to be conducted every 7, 14, or 30 days. Regulatory inspections are performed by agencies (e.g., EPA, state, or local municipalities) to determine compliance and are generally periodic or complaint-driven. Operator inspection records are usually reviewed during regulatory inspections. Learn more.

Can technology (e.g., apps, drones) be utilized for SWPPP inspections? 

Technology may usually be utilized for supporting SWPPP inspections for documenting, photographically logging, and recording corrective actions. The minimum requirements for a visual site inspection by trained staff, however, remains the same.
