Environmental Liabilities: Considerations For The Consulting Engineer
By Howard W. Ashcraft, Jr.


Test tubes and monitoring wells are replacing "sticks and bricks" in engineering practice. This transition creates new and exciting opportunities, but also profoundly affects the liabilities engineers face. New risk management strategies must be developed to balance risk and reward. This paper summarizes key factors affecting environmental liabilities and provides suggestions for minimizing these new environmental risks.

Environmental Claims-Qualitatively Different

Several factors make environmental claims more dangerous than traditional construction claims.

Leveraged Liability: Liability for environmental projects is often disproportionate to the fees earned. Errors in small projects can result in large liabilities. Because liability is least when knowledge of the site is greatest, environmental projects, such as site assessments, can even have liability that is inversely proportionate to the fee. Doing less may result in more liability.

Third Party Liability: Environmental claims are often made by persons the engineer has never met. This broad range of invisible claimants-lenders, purchasers or bystanders-increase the probability and severity of claims.

Strict Statutory Liability: Negligence is the primary standard applicable to construction professionals. Environmental professionals, in contrast, can be subjected to strict statutory liability. CERCLA and similar statutes can impose liability on the faultless.

Evolving Technologies: Fast changing technologies assure that better methodologies will be developed. Unfortunately, today's decisions may get measured by tomorrow's knowledge.

Changing Social and Regulatory Environments: Even if technologies remained constant, the social and regulatory frameworks change. Creative claimants will contend their engineers should have anticipated likely developments.

Long Tailed Liability: Most construction claims occur soon after construction is completed. Statutes of limitation and repose further serve to shorten liability exposure. Environmental claims may lie dormant for many years. When they awake, culpable parties may have disappeared, insurance may have vanished, and legal standards may have changed. The asbestos crisis evidences the distress caused by latent liabilities.

Criminal and Personal Liability: Environmental statutes often contain provisions imposing personal and criminal liability. The dangers inherent in such claims complicate defense of environmental claims. Conflicts of interests abound, privileges disappear and defense costs skyrocket.

Liability of Environmental Professionals Under CERCLA

Engineering consultants face environmental liabilities imposed by contract terms and traditional tort law. While the liabilities arising under these theories can be severe, the legal basis for such claims does not differ from traditional principles applicable to construction claims. The liability faced by engineering consultants under environmental statutes, however, can be substantially broader than allowed under traditional theories.

CERCLA, discussed below, is the leading statutory liability program. It is a template followed by many states. Although other statutory programs may also apply, the potential CERCLA exposures demonstrate the breadth of statutory liability.


CERCLA imposes strict5, joint and several liability6. Liability exists even if the engineer's conduct met the "standard of care." This broad liability standard, when combined with the expansive nature of environmental damages, drastically increases potential liability.

CERCLA defines four categories of responsible persons: owners, operators, arrangers and transporters7. Few engineers will be facility owners, but they can inadvertently be operators, arrangers or transporters. Operators are persons who operated a facility at the time a disposal of hazardous wastes occurred8. Arrangers are persons who by "contract, agreement or otherwise arranged for disposal or treatment, or arranged for transport for disposal or treatment of hazardous substances..."9 Engineers, particularly engineers engaged in design/build remediations, fall within the broad sweep of CERCLA's arranger language.10 Transporters are persons who accept hazardous substances for "transport to disposal or treatment facilities, incineration vessels or sites selected by such person..."11 Inadvertent transportation liability can arise when hazardous material is moved within a project site or when a "transporter" is significantly involved in disposal site selection.

Application of CERCLA to Environmental Professionals

Ganton Technologies, Inc. v. Quadion Corporation 12 and City of North Miami, Fla. v. Berger, 13 reflect contrasting approaches to the liability of environmental engineers. These decisions also demonstrate the increased liability inherent in design/build and environmental construction management.

In Ganton Technologies, the court held that a remediation contractor and the remediation engineer could be liable under CERCLA as "operators" of a remediation site. The court noted that both were alleged to have control over the remediation site. Amazingly, the court concluded:

The Ganton Technologies court shows little sympathy for the realities of consulting practice. The court did not recognize any distinction between those who "profit from disposal" and those who "profit by remediation." Both are liable under CERCLA. Further, the court found authority to control disposal, an essential element of CERCLA liability, because the engineer's reports indicated that the engineer actively supervised the contractor's work.15 While the court did not discuss the contents of the report, one can infer that the reports reviewed the adequacy of the contractor's work since the engineer argued that it merely observed the contractor's work.

A contrasting view appears in City of North Miami. The engineering firm contracted to design a landfill, assist with permits, and consult regarding operation, but was not liable under CERCLA. The engineer only provided advice and did not have the authority to control operations on the site.

The City of North Miami court expressed concern over extending CERCLA's reach to the many engineers providing opinions and advice, stating:

The North Miami court did hold that the contractor which constructed the landfill was liable under CERCLA as it had actual control over disposal.

The two decisions reflect opposing currents in CERCLA liability. Ganton Technologies assumes that CERCLA is furthered by holding remediation contractors liable since the profit (or hope to) from remediation. North Miami is cautiously opposed to extending liability. Taken together, the cases lead to three conclusions. First, an engineer's CERCLA liability will depend upon the view of the individual court in which an action is brought. Second, the characterization of an engineer's services in the proposal, contract and report is critical to liability. Authority to control or manage the remediation process must be avoided if CERCLA liability is to be escaped. Third, design/build engineers and contractors will almost always be subject to CERCLA liability. Design/builders must decide whether their increased control over project quality counterbalances the increase risks.

Application of CERCLA to site Remediation

Another pair of cases demonstrate CERCLA risks from a contractor's view. In Kaiser Aluminum vs. Catellus,17 the Ninth Circuit held a rough grading contractor jointly and severally liable for site clean-up costs. The court classified the contractor as an "operator" because it had control of the site and as a "transporter" because it moved hazardous materials from one portion of the site to another.

A contrasting view was expressed in Danella Southwest v. Southwestern Bell Telephone.18 In Danella a contractor excavated and removed dirt it believed was uncontaminated. After it had excavated some of the material and transported it to another site, it learned that the soil was contaminated with dioxin. The contractor was a proper party under CERCLA, but the court concluded that a zero liability allocation was appropriate.

Application of CERCLA to Transport and Disposal Decisions

Until recently, it was generally believed that transporter liability did not affect engineers unless they were engaged in physically transporting hazardous wastes. Two 1994 cases, however, cast doubt on the extent of transporter liability. In Tippins v. USX,19 the court held that a transporter that recommended four alternative waste disposal sites "actively participated" in the selection and was, therefore, liable under CERCLA. Although cast as a transporter case, the reasoning of the decision could be transferred to environmental consulting.

In contrast, the court in C.P. Systems v. Recovery Corp.,20 held that a disposal consultant was not liable as an arranger where it recommended a disposal site, found a transporter, and invoiced the owner for the marked up costs of transportation. The court compared the consultant's activity to the tasks undertaken in Emergency Technologies Services Corp. v. Morton International. In Emergency Technologies, the broker:

Although the broker's level of involvement in Emergency Technologies may have been greater than the consultant's involvement in C.P. Systems, the difference is slight. The different outcomes are more likely correlated to the specific court than to the specific facts.

State Statutes

There are a tremendous number of state statutes that concern environmental liabilities. Although many of these statutes do not directly discuss the liability of environmental engineers, expansive interpretations of these statutes could include holding engineering firms responsible without fault. HWAC publishes a review of state environmental statutes and regulations affecting environmental engineers.

Liability Mitigation Strategies

Mitigation strategies will vary with the type of project undertaken. A few general concepts apply to most projects.

Client Selection

Who the client is affects liability exposure. For example, a site assessment for a governmental body is less risky than a pre-purchase assessment for a real estate development syndicate. If the information will be distributed to many third parties, risk obviously increases. The first step in managing risk, therefore, is to critically examine clients to determine whether, and on what terms, the assignment is accepted. The following is a list of factors which may be useful in evaluating client based risks.

Project Selection

Project selection is an important component of risk management. General factors to consider include:

Quality Assurance/Creation Mechanisms

Quality assurance programs are especially significant in environmental projects. Since the magnitude of potential loss is great, any effort to reduce error is beneficial. Further, the existence of a quality assurance program may be required by the standard of care. Quality assurance may also assist in deflecting claims of willful violations of environmental statutes. Prosecutors have great discretion in determining whether to institute criminal proceedings. Evidence that the firm has a policy of searching for and preventing error can be used to persuade prosecutors that criminal proceedings are not warranted.

Total Quality Management teaches that inspection does not create quality. Quality assurance should create structures and systems that avoid error, rather than try to catch errors after they have occurred.

Contractual Protections

Scope and Limitations

Besides technical excellence, the best method for reducing the risk that work will be deemed to have breached the standard of care is often to carefully delineate the scope of work to be undertaken, including work which will not be performed. The analysis to be performed, the standards being used, and the limits on the investigation should be set forth in writing. This supports the argument that the work was correctly performed within the standards and limits imposed.

The scope of work is usually proven from three documents: proposal, contract and report. It is vital that they be consistent and that important limitations on the scope of work be echoed in all three documents. Many firms have QA/QC review of reports; the proposal and contract should have QA/QC review as well.

Third Party Reliance

The contract should explicitly limit reliance by third parties. This is accomplished by stating:

In conjunction with these limitations, the engineer can request that the client indemnify it from liability to third parties caused by unauthorized distribution or use of the report. If it is necessary to distribute the report to a third party, an agreement should be executed by the third party and the client which states that:

Limitation of Liability

With exceptions, one liability to a client can be limited by contract. Because liability limitations have little effect on third liabilities, they should be considered an element of a risk management plan, not a complete solution.

The limitation provision must be carefully crafted in concordance with the jurisdiction's specific rules and the client's specific needs.21

Consequential Damage Waivers

Many agreements contain provisions waiving consequential damages. These clauses can preclude claims for indirect economic loss and lost profits. Such losses are often the largest portion of an environmental claim.

Fines and Penalties Waivers

An engineer's failure to timely meet deadlines, discharge requirements or similar goals may result in imposition of significant fines against the client. If this is a significant risk, the engineer may wish to disavow responsibility for such fines and penalties.


Indemnification protects the engineer against claims by third parties. Indemnification, however, has four limitations. First, indemnification rarely provides complete protection. It is difficult to draft clauses that accomplish the exact result intended. The options are generally too strong or too weak to meet the parties' reasonable expectations. Second, indemnification law is complicated and quirky. Courts do not interpret indemnification clauses in accordance with their plain language.22 Third, many states have statutes that limit the scope of indemnification in construction agreements.23 Such clauses may preclude broad indemnification provisions. Fourth, indemnification depends upon the continued financial viability of the indemnitor. Indemnification is a valuable, but incomplete contractual protection.

Pre-existing Condition Waiver/Indemnification

Clients often resist broad indemnification or limitation of liability provisions. However, they can be convinced to accept liability for pre-existing contamination. Thus, the client may be willing to waive liability or indemnify the engineer against claims arising from contamination that existed before the engineer's services.


Environmental projects are qualitatively different from conventional construction or engineering projects and have a higher potential for loss. Current statistics are not sufficient to determine whether the higher potential for loss equates with higher risk. It appears that the actual risk depends upon a variety of factors, including some factors within the engineer's control. To achieve satisfactory relationships of profit and risk, project principals must understand and manage these risks.
