Question 1

What does an above ground storage tank expert witness do in environmental contamination cases?

Accepted Answer

An above ground storage tank expert witness evaluates whether an AST released petroleum or hazardous materials that contributed to soil or groundwater contamination. The expert examines tank integrity, secondary containment, piping, and appurtenances to identify leak pathways and timing. The AST expert witness reviews sampling data, hydrology reports, and historical operating records to distinguish tank-related releases from other potential sources. The storage tank expert correlates exceedances of environmental standards with tank failure events and assesses compliance with SPCC plans and state cleanup rules. The expert prepares causation opinions, allocation analyses, and remediation cost evaluations for use in settlement negotiations and trial testimony.

Question 2

How can a law firm find an AST expert witness for aboveground storage tank litigation?

Accepted Answer

A law firm can find an AST expert witness by searching specialized expert witness directories that categorize experts by above ground storage tank litigation and environmental engineering. Counsel should filter for storage tank experts with API 653 inspection credentials, STI SP001 training, and experience with SPCC compliance in the relevant jurisdiction. The firm should review curriculum vitae, prior deposition and trial testimony, and publications on tank failures or environmental contamination. Counsel may also assess whether the AST expert witness has managed aboveground storage tank inspection programs or designed storage tank systems in the United States. Screening interviews can confirm communication skills, conflict checks, and availability for deposition and trial.

Question 3

What qualifications should an AST expert witness have for United States regulatory compliance testimony?

Accepted Answer

An AST expert witness providing regulatory compliance testimony should typically hold an engineering degree and, in many cases, a Professional Engineer license. Strong candidates often maintain API 653 certification for above ground storage tank inspection and familiarity with UL-142, STI SP001, and related industry standards. The storage tank expert should demonstrate working knowledge of SPCC regulations under the Clean Water Act, state and local environmental rules, and applicable fire codes governing petroleum storage. Experience preparing SPCC plans, conducting compliance audits, and interacting with regulators strengthens the expert’s credibility. Prior deposition or trial testimony on regulatory compliance and enforcement actions further supports admissibility and weight of opinions.

Question 4

How does an API 653 inspection expert witness evaluate tank integrity and failure causation?

Accepted Answer

An API 653 inspection expert witness applies API 653 criteria to assess the structural integrity and fitness for service of existing above ground storage tanks. The expert reviews prior API 653 inspection reports, thickness measurements, settlement surveys, and non-destructive examination results. The storage tank expert analyzes corrosion rates, weld quality, floor and shell conditions, and roof configuration to identify deterioration or design weaknesses. In a tank failure dispute, the API 653 expert reconstructs the sequence of events and compares inspection findings with required inspection intervals and repair criteria. The expert determines whether proper repairs, coatings, and cathodic protection were implemented and whether deviations from API 653 contributed to the tank failure.

Question 5

When should counsel retain a storage tank expert witness in aboveground storage tank failure litigation?

Accepted Answer

Counsel should retain a storage tank expert witness as early as possible after an aboveground storage tank failure or release is identified. Early engagement allows the AST expert to participate in site inspections, evidence preservation, and joint testing protocols. The tank expert can advise on sampling locations, documentation of tank conditions, and chain of custody procedures that affect admissibility. Early expert involvement supports informed pleading decisions, insurance communications, and settlement evaluations. Retaining the AST expert witness before discovery closes ensures adequate time for report preparation, rebuttal analysis, and deposition scheduling.

Question 6

How can an AST expert witness assist with SPCC compliance and enforcement actions?

Accepted Answer

An AST expert witness assists with SPCC compliance by comparing facility design and operation to federal SPCC regulations and the facility’s written SPCC plan. The expert evaluates tank placement, secondary containment, overfill protection, drainage controls, and inspection programs for above ground storage tanks. In enforcement actions, the storage tank expert reviews inspection records, training logs, and incident reports to determine whether alleged violations are supported by technical evidence. The expert may propose corrective measures, such as containment upgrades, revised inspection frequencies, or improved leak detection. The AST expert witness prepares compliance opinions and can testify before administrative tribunals or courts regarding the adequacy of SPCC implementation.

Question 7

What documents and data should attorneys provide to an above ground storage tank expert witness?

Accepted Answer

Attorneys should provide the above ground storage tank expert witness with design drawings, construction records, and manufacturer specifications for each AST at issue. Inspection and maintenance records, API 653 reports, STI SP001 checklists, and repair documentation are critical for evaluating tank integrity. Incident reports, photographs, sampling data, spill response logs, and correspondence with regulators help the storage tank expert reconstruct events and assess environmental contamination. Counsel should also supply applicable SPCC plans, operating procedures, and relevant contracts or lease agreements. Providing complete data enables the AST expert witness to develop reliable opinions and prepare thorough written reports for litigation.

Question 8

How is aboveground storage tank expert testimony evaluated under Daubert or Frye standards?

Accepted Answer

Aboveground storage tank expert testimony is evaluated under Daubert or Frye standards based on the reliability and relevance of the expert’s methods and opinions. Courts assess whether the AST expert witness relies on widely accepted engineering standards such as API 653, UL-142, and STI SP001. Judges examine whether the storage tank expert applied these standards consistently to the facts of the case and used verifiable calculations or inspection data. The court may consider the expert’s peer-reviewed work, error rates of testing methods, and general acceptance in the engineering and environmental community. Clear, methodical reasoning and transparent reliance materials support admissibility of the tank expert’s testimony.

Question 9

What types of remediation and repair issues can an AST expert witness address?

Accepted Answer

An AST expert witness can address both remediation and repair issues that arise after a tank failure or release. The storage tank expert may evaluate proposed tank repairs, foundation improvements, and secondary containment upgrades for compliance with API and SPCC requirements. The expert can assess soil and groundwater remediation plans to determine whether they are technically appropriate for the type and extent of contamination. The AST expert witness may estimate reasonable remediation timelines and costs for litigation involving property damage or business interruption. The expert can also comment on the suitability of returning a repaired above ground storage tank to service or recommending decommissioning.

Question 10

What fee structures are common for above ground storage tank expert witnesses in the United States?

Accepted Answer

Above ground storage tank expert witnesses in the United States typically charge hourly rates for consultation, document review, report preparation, and testimony. Separate hourly rates may apply for site visits, deposition testimony, and trial appearances. Many AST expert witnesses require an initial retainer that is billed against future work. Some storage tank experts charge minimum fees for deposition or trial days to account for blocked time and travel. Clear engagement letters specifying billing rates, travel reimbursement, cancellation terms, and invoice schedules help align expectations between counsel and the AST expert witness.
