The 1978-79 Sludge War
October 1, 1999
Because of the recently revived interest in sewage sludge I have decided to memorialize the sludge battles in which I
was involved in 1978-79 during the early days of RCRA.
Keep in mind that the purpose of a sewage treatment plant is to capture the toxic substances and other bad stuff in
sewage and to concentrate it in the sludge. To start with, let me give you an idea of the kind of pressure EPA was (and
is) under to try to find some use for the millions of tons of sewage sludge being and expected to be emitted by the waste
water treatment plants funded by the EPA Construction Grants Program, the largest public works project ever in America.
Here is a quote from a letter written by the Seattle Sewer District to EPA in 1974(1) in response to the Agency's then
proposed guidance on "Methods for the Utilization or Disposal of Sludges". This was written long before RCRA and is
typical of the kind of pressure exerted then and still being exerted on EPA.
The limits suggested for the metal content of sludges will not allow many large cities to use Municipal sewage treatment agencies and their allies in the engineering, construction and fertilizer business dominated
sludge for agriculture unless the metal content is reduced. If metals are removed at the source,
it will represent a large cost to industry and ultimately to the consumer. There will be a demand
on the natural resources for the chemicals needed to remove the metals, and there will be
chemical and metal sludge to dispose of. If a cost benefit analysis is carried out, it would appear
doubtful that the value of using sludge in agriculture could equal the costs. The proposed
guidelines would appear to favor landfill or incineration.
the policy of EPA's Construction Grants Program and that policy was to remove any impediments to the flow of federal
money into the construction and operation of new sewage treatment plants. I saw an illustration of that domination when
I attended a meeting of a panel of the EPA Science Advisory Board in 1976 to evaluate a proposed Technical Bulletin
concerned with the health effects of using sewage sludge as fertilizer on crops. The EPA Science Advisory Board has a
reputation for scientific objectivity which was not evidenced in this meeting. The Chairman was the former head of the
Chicago Sanitary District and the originator of Chicago's sludge utilization program. In his opening remarks(2) he railed
against the "negative nature of the Technical Bulletin" and said "there would not be a municipal official that
would dare to approve land disposal in the form that report was proposed for our review". His bottom line
was "you wouldn't even get favorable interest rates on your municipal bonds". The panel then proceeded
to blast the Technical Bulletin without ever considering the human heath effects of sludge utilization. As a
result, the bulletin was revised so as to be toothless. So much for science.
Earlier, in 1975, the Hazardous Waste Management Division, in which I was a Branch Chief, was working with
Congressional staffers interested in drafting legislation to regulate hazardous waste disposal. Since many municipal
sludges would meet any reasonable definition of a hazardous waste, I wrote a memo(3) warning of the
implications of including municipal sewage sludge in the definition of solid waste in any of the proposed bills that were
being discussed. In light of the Construction Grant Juggernaut, we did not want to be involved in that can of worms. In
that memo I concluded:
What will happen, then, if Congress gives EPA regulatory authority over hazardous wastes? Will Nevertheless, when RCRA became law in October of 1976, municipal sewage sludge was included in the

authority or by changing EPA sewage sludge policy.
definition of solid waste and my worst fears came true. As we shall see, the result of this inclusion was not to
strengthen the laws concerning the safe use of municipal sludge but rather to weaken the regulation of hazardous
A few months after RCRA went into effect Thomas Jorling was named Assistant Administrator for Water. Jorling had
previously been a Congressional staffer credited for being instrumental in passing the Clean Water Act. One of his first
actions was to get the Office of Solid Waste (i.e. my office) transferred to his Water Office so that he now had jurisdiction
over municipal sewage sludge and hazardous waste(4). The Water Office (OWPO) made it very clear that it could
not live with any sewage sludge being labeled a hazardous waste. My boss, Jack Lehman, wrote(5): "Will the
hazardous waste definition mean that some/much municipal wastewater treatment sludge is labeled 'hazardous' due
primarily to heavy metal contamination? If so, OWPO wants the definition changed."
I was in charge of writing the RCRA 3004 regulations for the treatment, storage and disposal of hazardous waste. I did
not see how we could regulate hazardous waste from industrial plants differently from similar waste from waste water
treatment plants, especially in light of the fact that a great deal of the input to municipal waste water treatment plants is
from industrial sources. A compromise was proposed(6) which would exempt sewage from RCRA regulations (and the
opprobrium of having some sludge labeled "hazardous") and regulate it under the Clean Water Act under the condition
that the Water Office regulations for defining and treating the sludge would be identical to those which would apply if
regulated under RCRA.
However, the Water Office was anxious enough to go along with that aspect of the compromise dealing with the transfer
of jurisdiction but was less anxious to accept the need for equivalency of the regulations. I pointed this out to Lehman in
a memo(7) concluding:
I should think that in regulating pollution which its own regulations and funds created, EPA The debate between the two offices continued throughout that summer(8). Human health considerations took a

advantage of its position to write lesser standards for its own pollution it will surrender the
moral leadership it now commands.
back seat to the need to keep the money and the sludge flowing without additional costs, which were already
astronomical. Rationalization substituted for science in the Water Office which believed its own propaganda that:
Sludge should be covered [i.e. regulated] independently because it contains nutrients and In fact sewage sludge contains very little in the way of nutrients relative to commercial fertilizers, so much so that some
organic matter which have considerable benefit for land and crops. Most industrial wastes do
not have such benefit(9).
sanitary districts add nitrogen to their sludge in order to give it away(10). Furthermore, many instances of land farming
industrial wastes were known at the time(11).
The draft standards prepared by my office(12) limited the arsenic, cadmium and lead which can be applied as soil
amendments made from hazardous waste. At the intra-agency meeting to review these draft standards the Water Office
objected that the regulations for arsenic, cadmium and lead may set a dangerous precedent for the Section 405 (i.e.
By September, everyone involved recognized the futility of resisting the sludge juggernaut -- everyone but me, that is. I
was finally instructed by Gary Dietrich, Jorling's hatchet man, to weaken the standards for land farming hazardous
industrial waste to the comfort level of the Water Office, regardless of the consequences to human health(14) And the
consequences of this cruel decision were indeed far ranging and severe as not only sewage sludge but
raw industrial hazardous waste is "recycled" into fertilizer to this day(15). Eight days after this decision I was
Different people handled the defeat in different ways. I became a whistleblower(17). My ex-boss, Jack Lehman,
consoled himself with the knowledge that there was a potential medical treatment for the people we were
poisoning(18). And Bob Tonetti wrote the definitive letter to the Washington Post(19).
The Environmental Protection Agency is in need of being told not to waste hundreds of millions of taxpayer ROBERT TONETTI
dollars. I believe the problem to be mismanagement. You judge:
The clean Water Act requires EPA to develop regulations for the disposal of sewage sludge. The
agency is already six months--and could be another 18 months--late in meeting the act's
mandate. Meanwhile, cities such as New York, Boston, Philadelphia, Los Angeles and many
others venture on with development of local sludge programs. When EPA finally completes its
regulations, many of these programs may be found inadequate particularly those that distribute
sludge for homeowner use as mulch or soil conditioner.
More than two years ago, the General Accounting Office requested that EPA provide
"immediate" guidance on sludge distributed to the general public because of "potential health
hazards." This guidance has not yet been provided. Highly contaminated back-yard soils have
now been found In Chicago, where sludge was used as a mulch. Thousands of Chicago-area
back yards have been contaminated in a program that continued for one year following GAO 's
warning to EPA. Many similar programs are still ongoing nationwide--without restriction.
The position of EPA's construction grants program has been the biggest factor in the delay of
the sludge regulations. Construction grants provide funding for the planning, design and
construction of sewage-treatment plants. These are the plants generating the sludge that
another part of EPA, the Office of Solid Waste, has responsibility for regulating. Since 1973,
construction grants have provided cities some $22 billion, of which sludge systems take up no
small portion. The grants program has assisted the cities so well, it's often hard to tell the
regulators from the regulated.
This "industry's" influence was primarily responsible for the exemption of municipal sludge from
EPA's proposed hazardous-waste regulations. The exemption will apply even though some
sludges contaminated with industrial wastes can be quite hazardous.
The construction-grants program should not be capable of so strongly influencing other offices
in EPA that are charged with regulating certain aspects of sewage treatment and disposal.
Perhaps the grants program should be set in some corner of EPA where this influence could not
be exerted. Or, maybe placed in another agency altogether. (Please not the Army Corps of
