Case Overview, Effluent Guidelines for Tank Trucks
This document provides background information and summarizes the debate over
EPA effluent limitation guidelines. The links to the left

The Clean Water Act authorizes the Environmental Protection Agency (EPA) to
regulate industries whose business practices may contribute to water pollution.
Individual industries present different problems and EPA must write separate
regulations to meet the specific issues in water quality that have emerged in
each relevant business sphere. EPA began its implementation of this part of
the Clean Water Act with the industries where it perceived the problems to be
most urgent. Over time environmental groups became impatient with the agency's
pace and began taking it to court for failing to regulate industries the lobbies
believed were producing significant water pollution. One of these suits targeted
EPA's failure to regulate the tanker truck industry.
Tanker trucks are
specialized vehicles used to transport liquid products, some of which (chemicals,
pesticides, gasoline) are quite dangerous. Said one participant in the policymaking
on this matter, "Think of a tank truck as a thermos bottle. It's got insulation
and stainless steel and you can keep things warm or cold, the stainless protects
the tank itself from whatever chemicals they haul." After they've delivered
their cargo, the inside of the "thermos bottle" needs to be cleaned.
With solvents or other chemicals each tanker truck is thoroughly washed. It's
the wastewater from this process, containing both the residual from the original
cargo and the cleaning solvents, that produces the problem. Where do you put
it? "Obviously you don't just go out in the yard with it," noted one
industry observer.
The regulation writing
process, known as "administrative rulemaking," is sometimes contentious
as a governmental agency may produce rules requiring individual companies to
spend significant sums to change their manufacturing process to reduce pollution.
New regulations could allow more companies to compete in a particular business
market, thus threatening the profits of current competitors. In the case of
the tanker trucks, the rulemaking process was fairly consensual as EPA and industry
representatives worked cooperatively to produce these new regulations. After
EPA notified the industry that it would be initiating administrative rulemaking,
EPA officials were invited to visit some tank cleaning facilities so they could
better understand industry practices. For its part EPA had scientific expertise
in water quality and engineering that the industry lacked and the agency shared
its data with the tanker truck companies and their trade association. In turn
the trade association hired consultants and a Washington law firm with the requisite
technical expertise to work with EPA during the writing of the regulations.
The tanker truck
industry is made of small businesses and EPA was sensitive to the need to formulate
regulations that would keep any new company expenditures within reasonable bounds.
EPA's efforts in this regard were aided by its Small Business Advocacy Office,
whose director became involved in the rulemaking proceedings. Federal bureaucracies
are encouraged in this respect by the Regulator Flexibility Act and the Small
Business Regulator Enforcement Fairness Act to write regulations in a fashion
realistically compatible with the financial resources of small business in mind.
The rulemaking also went smoothly because the technical problems of disposing
of the tanker truck wastewater are not formidable. Current practices in the
industry were not too far off from what the new regulations eventually required.
