Inspection Data Shows Common Hazardous Waste Violations

We decided to take a look at some of the EPA enforcement sites to review hazardous waste violations issued across the U.S. within the past couple of years.

We decided to take a look at some of the EPA enforcement sites to review hazardous waste violations issued across the U.S. within the past couple of years. We wanted to see if there were some common themes that readers should be on the lookout for. Here are some of the most common items we found: Container and Labeling Issues, Inspections, Training, Waste Determinations, Contingency Plans, Tanks and Air Emissions, and other items. iSi can help with all things hazardous waste.

TL;DR: EPA enforcement data reveals seven recurring violation categories: improperly labeled/maintained containers, missed inspections, insufficient or undocumented training, incorrect waste characterization, missing or inadequate contingency plans, tank/air emissions non-compliance, and record-keeping gaps. Each carries separate civil penalties; stacked violations can exceed $10,000 per day per facility.

What’s at Risk: Hazardous waste violations are strict-liability violations—intent doesn’t matter. A single EPA inspection can identify container labeling gaps, expired training records, or missing inspection logs that trigger immediate financial penalties and facility-wide remediation orders. Facilities without documented procedures and proof of compliance training face escalating enforcement, potential criminal referrals for repeat violations, and insurance claim denials.

Frequently Asked Questions

Q: What are the most common EPA hazardous waste violations found during inspections?

EPA enforcement data from recent years shows common hazardous waste violations fall into several categories: Container and Labeling Issues (improper containers and illegible labels), Inspections (failure to conduct required equipment or facility inspections), Training (inadequate or missing hazardous waste training), Waste Determinations (failure to properly characterize waste), Contingency Plans (inadequate or missing emergency response plans), and Tanks and Air Emissions compliance issues.

Q: Why are container and labeling violations so common in hazardous waste operations?

Container and labeling violations frequently occur because facilities fail to maintain proper container integrity, use inappropriate container materials, or apply illegible or missing hazard labels. EPA requires all hazardous waste containers to be properly identified with hazard classification, accumulation start dates, and chemical contents. These violations are easily preventable with proper procedures and training.

Q: What training gaps does EPA enforcement data reveal?

Hazardous waste training violations indicate that facilities are not conducting required employee training or are failing to document training completion. EPA requires training before employees handle hazardous waste and refresher training to maintain compliance. iSi Environmental recommends annual training audits and documentation to prevent violation citations.

Q: What is a Contingency Plan and why is it frequently violated?

A Contingency Plan is an emergency response procedure required for hazardous waste facilities, detailing actions to take in case of fires, explosions, or spills. EPA violations occur when plans are missing, inadequate, or not updated to reflect current facility operations. Contingency Plans must include emergency procedures, emergency coordinator identification, and notification procedures.


Full EPA hazardous waste audits start at $1,500 for container/labeling/training record review. Comprehensive RCRA audits with contingency plan updates and staff training run $3,000–$7,500 depending on waste streams and site complexity.
