Common Stormwater Violations & How to Avoid Them

Stormwater regulations are in place to protect our water resources, but non-compliance can lead to costly fines and environmental damage. Property managers, developers, and contractors must stay vigilant to ensure their stormwater systems function correctly and remain compliant with local, state, and federal guidelines. Below, we outline the most common stormwater violations and how you can avoid them.

1. Failure to Maintain Best Management Practices (BMPs)

The Violation:

Stormwater Best Management Practices (BMPs) are designed to prevent pollutants from entering waterways. Common BMP failures include clogged or damaged storm drains, deteriorating retention ponds, and malfunctioning filtration systems.

How to Avoid It:

• Schedule regular inspections and maintenance for all stormwater infrastructure.
• Keep records of inspections and repairs to demonstrate compliance.
• Ensure stormwater features, such as detention ponds and bioswales, remain free from debris and sediment buildup.

2. Inadequate Erosion and Sediment Control

The Violation:

Construction sites are particularly prone to erosion issues, with disturbed soil easily washing into storm drains. Failing to implement sediment control measures can result in significant fines and environmental harm.

How to Avoid It:

• Use silt fences, straw wattles, and other sediment control barriers properly.
• Stabilize exposed soil with hydroseeding, hydromulching, or erosion control blankets.
• Conduct frequent site inspections, particularly after heavy rainfall.

3. Illicit Discharges into Stormwater Systems

The Violation:

An illicit discharge is any non-stormwater substance entering a storm drain, including chemicals, oils, detergents, or sewage. These pollutants can degrade water quality and pose health risks.

How to Avoid It:

• Train employees and contractors on proper disposal methods.
• Implement spill prevention and response plans.
• Conduct routine inspections to detect and address potential contamination sources.

4. Improper Storage of Hazardous Materials

The Violation:

Leaving chemicals, fuels, or waste materials exposed to rain can lead to contamination of stormwater runoff. Many facilities fail to implement secondary containment measures, increasing the risk of pollution.

How to Avoid It:

• Store hazardous materials in covered, spill-proof areas.
• Use secondary containment solutions, such as spill pallets or berms.
• Label hazardous materials clearly and follow proper disposal protocols.

5. Lack of Stormwater Pollution Prevention Plan (SWPPP) Implementation

The Violation:

A Stormwater Pollution Prevention Plan (SWPPP) is required for many construction and industrial sites. Failure to develop, maintain, or follow an SWPPP can lead to regulatory action.

How to Avoid It:

• Ensure your SWPPP is up to date and site-specific.
• Train staff on SWPPP implementation and compliance.
• Conduct regular audits to verify adherence to the plan.

6. Neglected Retention and Detention Ponds

The Violation:

Retention and detention ponds are essential for managing stormwater runoff, but without proper maintenance, they can become ineffective. Overgrown vegetation, sediment accumulation, and clogged outlets are common issues.

How to Avoid It:

• Remove excess vegetation and debris regularly.
• Dredge sediment buildup to maintain storage capacity.
• Inspect pond structures, including outflow pipes, for damage or blockages.

7. Failure to Obtain Necessary Permits

The Violation:

Many stormwater-related activities require permits from local or federal authorities. Operating without the appropriate permits can result in legal and financial consequences.

How to Avoid It:

• Check with local, state, and federal agencies to determine required permits.
• Apply for permits before beginning any land disturbance or stormwater-related project.
• Keep copies of permits onsite for inspection purposes.

Stay Compliant & Protect Water Resources

Avoiding stormwater violations not only prevents fines but also helps protect the environment and maintain a positive reputation. Partnering with stormwater management professionals can ensure your site remains in compliance with regulations. Regular inspections, proper maintenance, and proactive planning will keep your stormwater system operating effectively.
