Coal Combustion Residuals Impoundment

Assessment Reports

As part of the US Environmental Protection Agency’s ongoing

national effort to assess the management of coal combustion

residuals (CCR), EPA is releasing the final contractor reports

assessing the structural integrity of impoundments and similar

management units containing coal combustion residuals,

commonly referred to as “coal ash,” at coal fired power plants.

Most of the impoundments have been given hazard potential

ratings (e.g. less than low, low, significant, high) by the state,

EPA contractor, or company which are not related to the

stability of the impoundments but to the potential for harm

should the impoundment fail. For example, a “significant” hazard

potential rating means impoundment failure can cause economic

loss, environmental damage, or damage to infrastructure.

EPA has assessed all of the known units with a dam hazard potential rating of “high” or “significant” as

reported in the responses provided by electric utilities to EPA’s information requests and additional

units identified during the field assessments. EPA will release additional reports as they become

available.

The reports being released now have been completed by contractors who are experts in the area of

dam integrity, reflect the best professional judgment of the engineering firm, and are signed and

stamped by a professional engineer. The reports are based on a visual assessment of the site,

interviews with site personnel, and the review of geotechnical reports and studies related to the

design, construction and operation of those impoundments, if available. The engineering firms also

reviewed past state/federal inspections of the impoundments. EPA contractors were not authorized to

conduct any physical drilling, coring or sampling while on site; however, they did review studies which

may have included such information. These reports include complex engineering evaluations and use

terms which may be unfamiliar to the general public. Also, the contractors were asked to rate the

impoundments as “satisfactory,” “fair,” “poor,” or “unsatisfactory,” terms commonly used in the field of

dam safety. Expert experience has shown that only impoundments rated as “unsatisfactory” pose

immediate safety threats. None of the impoundments assessed so far have received an

“unsatisfactory” rating. Impoundment ratings noted in the reports should be taken in the proper

context, since a unit may be found to be structurally sound while it may receive a fair or poor rating

based on other factors such as lack of information.

Draft copies of these reports have been reviewed by the facilities and the states for factual accuracy

and their comments on the draft reports have also been posted. EPA continues to review the reports

and the technical recommendations, and is working with the facilities to ensure that the

recommendations are implemented.

EPA has provided a copy of the final report to each facility and has requested that the facility

implement the recommendations in the reports and provide plans for taking action. These plans are

being posted below as they become available. Should facilities fail to take sufficient measures, EPA will

take additional action, if the circumstances warrant, and will be devoting special attention to those

facilities receiving a “poor” rating.

The companies in the table below have at some point claimed some information they have provided

to the EPA related to their coal ash impoundments is confidential business information (CBI). While

EPA reviews these claims, the information that is claimed as CBI is not posted to EPA’s website. If

these claims are accepted by the EPA, the coal ash reports will be posted in redacted form. If EPA

denies these claims, all the information will be made publicly available and posted to this website.
