Are Electric Transformers A Recognized Environmental Condition?

Electric transformers are found at almost every larger commercial, institutional and industrial facility. Sometimes this equipment is owned by the facility owner and sometimes by the power company. For some facilities, it is not always clearly understood who owns and is responsible for transformers.

Can Electric Transformers Leak Oil?

Yes, electric transformers can leak oil, but only if they actually contain oil.

How Can I Tell If Electric Transformer Contains Oil?

For newer transformers, the quantity of oil in the unit is usually found on the label. For older equipment, this information may not be on the label, or the label may have been removed or is illegible. In this case, a visual inspection of the equipment by a knowledgeable person can usually determine if it contains oil or not.     Not sure?   Send Caltha a photo and we may be able to determine this - send to info@calthacompany.com

Who Is Responsible To Clean Up Leaks From Transformers?

This will depend on State laws. In general, the Owner of the equipment is responsible. However, for a property owner whose property has been impacted by a leaking transformer, the issue could affect the value of the property and they may voluntarily elect to clean up leaks.

What Are The Environmental Risks For Electric Transformers?

A risk for oil spills exists for any oil-filled transformer. Older transformers commonly contained PCB oils. Use of PCB oils has been phased out and newer equipment is often labeled "No PBC"; however older electric transformers could still contain PCBs which makes clean up more involved.

Leaks can occur over long periods and accumulate slowly. The other risk is an emergency spill caused by a fire or the transformer being damaged by vehicles, etc. These risks are minimized by ensuring equipment is included in pollution prevention plans and spill plans (such as SWPPP, SPCC Plan or other spill plans) and is regularly inspected and maintained. Whether or not an individual transformer is a Recognized Environmental Condition will be determined by the Environmental Professional after considering these factors.

How Long Does It Take To Do A Phase I?

This is one of the most common questions we receive.

How Long Does It Take To Do A Phase 1?


Answer: 10 business days for the vast majority of Phase 1 Environmental Site Assessments. There are a few situations where additional time may be required:
  • Property owner does not allow timely access to the property for an on-site inspection,
  • There are old issues on a property, such as leaking tanks, and the owner can not provide reports or other documentation to determine residual risks for the property. In this case a physical review of agency files may be required.
Fortunately, these types of situations are not encountered frequently and most Phase I assessments are completed within 2 weeks.

What Does A Phase 2 Environmental Assessment Do?

What Is A Phase II Environmental Site Assessment?

A Phase 2 Environmental Site Assessment follows a Phase 1 Environmental Site Assessment and investigates the Recognized Environmental Conditions, or REC, identified in the Phase 1 report. A Phase 2 investigation (sometimes referred to as a Limited Site Investigation or LSI) is intended to confirm the presence or absence of actual chemical or petroleum releases from each of the REC listed in the Phase 1 report. If no RECs were found during the Phase 1 ESA, then a Phase 2 investigation would not be needed.

 In most cases, the Phase 2 Environmental Site Investigation will collect soil, groundwater or soil vapor samples near the locations of the RECs. Samples are then sent to a laboratory for chemical analysis. The Phase 2 is considered a "limited" site investigation because the scope to limited to investigating the presence or absence of actual chemical or petroleum releases from each of the REC listed in the Phase 1 report.

During Phase 2 Site Investigation

 If no indications of chemical or petroleum releases are found, then the site investigation ends. If the results show that some releases have occurred, State and Federal laws may require reporting to the appropriate agencies. In this case further investigation may be required to determine the magnitude and extent of the contamination and to determine if site remediation is needed. The subsequent investigations are sometimes referred to as Phase 3 Environmental Site Assessments and are not typically included during Phase 2 investigations.

What is A Recognized Environmental Condition? What Is A REC?

What is A Recognized Environmental Condition?

A Phase I Environmental Site Assessment conducted to meet ASTM E 1527:2013 is intended to identify Recognized Environmental Conditions, or REC, associated with a property. Simply, a REC is a condition in which a spill, leak or other type of release to the environment or inside a structure has occurred, has potentially occurred or has a reasonable threat of occurrence in the future. It could be a condition that is visible at the site, such as staining around a fueling areas, or conditions no longer present, such as historical maps indicating a gas station was once present on the property.

 ASTM E 1527:2013 defines a Recognized Environmental Condition as: "the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment. The term does not include de minimis conditions that a condition that generally does not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies."
