has 30 years experience related to assessing and managing environmental
issues involving the presence and effects of contaminants in sediment,
water, soil and biota. He successfully deals with ecological, regulatory
and management aspects of such issues for a variety of industrial
and governmental clients. His activities include technical conduct
of projects, scientific consultation with clients, evaluation and
management of contaminated sediments, assessment and management
of potential impacts of dredging and dredged material placement,
ecological risk assessment, regulatory review and negotiation, technical
support of counsel and public interaction. Dr. Peddicord holds a
B. S. degree in Biology from Morehead State University, and a Ph.
D. in Marine Science from the Virginia Institute of Marine Science,
University of Virginia.
Material Management - Dr. Peddicord was compiler
and technical editor of the 1977 and 1991 EPA/CE joint testing manual
(the Ocean Testing Manual or "Green Book") for evaluation
of all dredged material proposed for placement in the ocean in the
United States. This required development of regulatory and technical
consensus among US Environmental Protection Agency (EPA) and US
Army Corps of Engineers (USACE) Headquarters, Regions and Districts
on dredged material toxicity and bioaccumulation testing, sampling,
chemistry, statistics, QA/QC and evaluation of results to determine
compliance with requirements of 40 CFR 227. For the USACE Dr. Peddicord
prepared the draft of the Upland Testing Manual, providing guidance
on evaluation of effluent, runoff, leachate, volatilization and
plant & animal bioaccumulation from dredged material proposed
for placement at upland sites. He authored an environmental guide
on pre-dredging investigations for materials characterization for
the International Association of Dredging Companies (IADC). Dr.
Peddicord helped develop comments on the proposal to close the New
York Mud Dump Site and designate the HARS, demonstrating a way to
accomplish the proposed remediation much more quickly than the EPA
recommended action. He evaluated potential upland sites for placement
of material dredged from Winyah Bay for South Carolina State Ports
Authority, and was technical lead on dredged material testing and
evaluation for the EIS for the Daniel Island Terminal. He evaluated
potential impacts of the proposed open-water placement Site 104
in Chesapeake Bay, including benthic toxicity and bioaccumulation,
water quality, and mixing zone acceptability. Dr. Peddicord scoped,
organized and conducted a national forum on Long-Term Management
Strategies (LTMS) for Dredged Material for the USACE. This brought
together national leaders from Federal and State regulatory agencies,
port industry, dredging industry, coastal zone management, economic
development agencies, environmental groups, planning agencies and
resource management agencies to discuss optimal management of dredged
Peddicord led an ecological and human health risk assessment of
dioxin associated with dredged material for the Port Authority of
New York and New Jersey. Dredging and placement activities were
addressed, and results were presented in such a way that they could
easily be used to evaluate dioxin in any dredged material handled
in the typical manner. Results indicating very little risk associated
with the material in question were presented at public hearings
on two dredging permit applications. Dr. Peddicord managed an ecological
and human health risk-based remedial investigation of sediment and
soil along a brackish-water bayou for a major petrochemical company
under a State consent order. He obtained State concurrence on chemicals
and receptors of concern and on specific locations to be addressed,
thus limiting the study area and potential client liabilities. He
was co-chair of the Navigation Dredging Work Group at the 1995 by-invitation-only
Pellston Workshop on Sediment Ecological Risk Assessment sponsored
by Society of Environmental Toxicology and Chemistry. Dr. Peddicord
was an invited presenter and Work Group co-chair at the 1997 Corps
of Engineers Workshop on Environmental Risk Assessment and Dredged
Material Management: Issues and Applications. Dr. Peddicord incorporated
risk assessment principles into the draft Upland Testing Manual
developed for USACE.
- Dr. Peddicord wrote the technical document that served as basis
for Chief of Engineers' policy letter on use of sediment
quality guideline values by the Corps of Engineers.
He developed technical comments for two major trade groups on EPA's
proposed sediment quality criteria and Contaminated Sediment Management
Strategy. From 1994 through 2003 he has been Scientific Advisor
to the International Association of Ports and Harbors at the London
Convention, the primary international treaty regulating ocean disposal
of dredged material and other substances. While with the USACE,
he served as a technical consultant to the Office, Chief of Engineers,
on national and international regulation of dredged material. He
was a major contributor to technical aspects of the dredged material
regulations implementing Section 103 of the Marine Protection, Research
and Sanctuaries Act, and to the dredged material testing requirements
for implementing Section 404 of the Clean Water Act. He served for
10 years on the EPA/CE Technical Committee on Criteria for Discharge
of Dredged and Fill Material.
- Dr. Peddicord was appointed to the National Academy of Sciences'
National Research Council Marine Board Committee on Contaminated
Marine Sediments. He has made presentations to the USACE Environmental
Advisory Board, EPA's Science Advisory Board, the Marine Board of
the National Academy of Sciences, and the Congressional Office of
Technology Assessment. He was an invited participant in the 2001
National Academy of Sciences Workshop on Dredging Windows. He chaired
four workshops on sediment bioassay implementation and evaluation
for the Corps of Engineers. Dr. Peddicord was a US delegate to the
8th and 13th US/Japan Experts Meeting on Management of Bottom Sediments
Containing Toxic Substances. He was also a delegate to the US/Netherlands
Memorandum of Understanding on Dredging and Related Technology.
He is a member of the Environmental Committee of the Western Dredging
Association, a professional organization of North, Central and South
of Counsel -
Dr. Peddicord has appeared as an expert witness on environmental
impacts of contaminants before the House Committee on Resources,
the House Committee on Merchant Marine and Fisheries three times,
the House Committee on Science and Technology, and the House Committee
on Public Works. He prepared affidavits based on his scientific
expertise for three major national litigations concerning environmental
issues. He provided expert testimony on environmental management
of dredged material in New Zealand court proceedings. Dr. Peddicord
provided technical support to counsel representing a dredging permit
applicant in New York. In support of counsel on behalf of a confidential
industrial client, Dr. Peddicord succeeded in refocusing a proposed
sediment regulatory action into a much more environmentally sound
and implementable approach.
- Dr. Peddicord managed a number of comprehensive sediment evaluation
and remediation projects, many conducted under federal or state
compliance orders, for major industrial clients. These projects
involved fisheries, benthic and avian ecologists, environmental
chemists, hydrologists, geologists, regulatory analysts, toxicologists
and civil and environmental engineers in problem identification
and assessment, ecological and human health risk assessments, evaluation
of remedial alternatives, recommendations of solutions, and securing
concurrence on the recommendation from state and federal regulatory
officials. During his 10 years at the US Army Engineer Waterways
Experiment Station, Dr. Peddicord played a key role in conceptualizing,
developing and conducting both the 5-year $8.7 million joint EPA/CE
Field Verification Program and the Long-term Effects of Dredging
Operations Program, the USACE's major ongoing research program on
environmental impacts of contaminated sediments, dredging and placement
under various conditions. He also played a major role in the Dredging
Operations Technical Support Program, designed to assist regulatory
authorities in applying the findings of scientific research.
is the author of over 60 national and international scientific papers,
reports and presentations specifically dealing with environmental
assessment and management of sediment and dredged material.
