- 00// Number 1 August 1989 Contaminated Sediments News Progress Report on EPA Sediment Contamination Oversight Committees The Office of Water Regulations and Standards (OWRS) formed two Agency- wide committees last summer to iden- tify, coordinate and provide guidance on activities relating to the assessment and management of sediments contaminated with toxic chemicals: a Sediment Over- sight Technical Committee and a Sedi- ment Oversight Steering, or Policy Committee. The goal of these Commit- tees is to facilitate decisions made at various stages in the management process such as 1) assessing sediment contamination, 2) deciding on the need for and type of management action, and 3) evaluating types of remediation (if relevant). In addition to this newsletter, the Sedi- ment Oversight Committees are cur- rently engaged in a number of projects. Two of note are 1) compilation of sum- maries of EpA Program Office activities related to ountaminated sediment is- sues, including specific statutes under which these activities fall (EPA Program Summary Document), 2) Preparation of a Sediment Classification Methods Compendium which describes the vari- ous methods used to evaluate sediment contamination, including their advan- tages, limitations, and existing applica- tions. CS News is produced by EPA- OWRS to exchange relevant infor* mation on contaminated sediments and to increase communication among interested parties.

Sediment Activities Around the Country EPA Criteria & Standards Division On Feb 2-3,1989, the Sediment Criteria Subcommittee of the Environmental Effects Transport and Fate Committee of the Science Advisory Board (SAB) met to review the appropriateness of the Equilibrium Partitioning (EP) Approach method for generating sediment criteria for nonionic contaminants. The SAB findings will be published in a report which is expected to be available this summer. The Criteria & Standards Division (CSD) prepared a briefing document for the SAB to provide pertinent information and data on the EP Approach. This document is available from Chris Zarba at (202) 475-7326. Superfund A draft report, "Nature and Extent of Ecological Effects at Superfund Sites" is available from Craig Zamuda (202) 382-2763.

For a copy, contact Sam Williams at (202)382-5980.' ORD-Duluth The Duluth lab is currently studying the uptake of dioxin and dibenzofurans in fish from Lake Ontario sediments. A mathematical model is also being devel- oped which will relate the contamination of sediments to measured effects (toxic- ity). Other projects include a joint study with the Great Lakes National Program Of- fice (GLNPO) to conduct sediment tox- icity studies on the Fox River in Wiscon- sin, identification of causes of sediment tpxicity, development of sediment crite- ria for metals, and development of chronic toxicity methods with several benthic species. Region I Region I, in conjunction with the New England Division of the Corps of Engi- neers (NE-COE), has developed proto- cols for testing dredged material within the framework of the existing National Ocean Dumping Guidelines. These protocols will standardize chemical and biological testing of dredged material for permit applicants &ho wish to dis- pose of the material in open waters. The region received agency concur- rence on the protocols in June and expect an operating program in place by September. A QA/QC program is being phased in for labs participating in the testing of the sediments for ocean disposal permits. For more information contact Dave Tomey at (617) 565- 4425. In a coordinated effort between EPA and the NE-COE, a pilot project is un- derway to evaluate the feasibility of dredging and disposing of PCB con- taminated sediments in New Bedford Harbor. New Bedford Harbor is the largest Superfund site in Region I, con- sisting of 18,000 acres of estuary, har- bor and bay highly contaminated with PCBs and heavy metals. Region V is part of an inter-agency task force studying the effects of disposed dredged material at confined disposal facilities (CDFs). A pilot study of model- ing and field studies at a Saginaw Bay CDF is underway (by ORD-Grosse He) to determine if biota inhabiting the out- side dike walls are accumulating con- taminants as a result of leakage of PCBs through the dike wall. The first year field effort (1987) focused on es- tablishing a methodology for sampling PCBs. [This report is available from Marc Tuchman at (312) 886-0239.] The second year field effort quantified the release of PCBs through water quality sampling and biomonitoring. Region V has completed an overview of state sediment programs in the region. They are currently working with the states to develop an inventory of contaminated sediments. Eventually the region wants to develop consistent assessment and prioritization protocols and develop site specific remedial options for sites with contaminated sediments. A settlement has been reached be- 2 property adjacent to the harborwhich have PCB concentrations greater than 10,000 ppm will also be treated using the on-site extraction process. Region X In February, Region X sponsorec workshop with the WA Departmenl Ecology on developing sublethal bio. says on the polychaete Neanthes. The State of Washington is currently c veloping state sediment quality stc dards. Several methodologies, irtcli ing the Apparent Effects Threshc (AET) Approach and the Equilibrii Partitioning (EP) Approach, are bei, considered as the technical basis I these standards.

The remedial actions involve removing any harbor sediments with PCB concentrations greaterthan 50 ppm. Sediments in the harbor slip area with PCB concentrations greater than 500 ppm will be treated on site using a low temperature thermal extraction process called Taciuk. Those harbor sediments which have PCB concentrations between 50 ppm and 500 ppm will be placed in containment cells. Sediments on the CONTAINMENT CELL CROSS SECTION SOIL CLAYTU. SCURRY WALL/ MONITORING WELL The geochemical data from thes samples are stored in the RASS (Roc Analysis Storage System) data base which contains the chemical composi tion of approximately 700,000 sample: of sediments, rocks, soils, plants, an< water from the United States (identifiec by state, county, and latitude and longi tude). The Water Resources Division o USGS also collects samples of strearr sediments for a variety of their pro grams, two of these being the Nations Water Quality Assessment Prograrr (NAWQA), and the Toxic Substances Hydrology Program. Stream sediment data from these pro- grams are stored in a data base called WATSTORE, or in RASS.

American Society of Testing Materials (ASTM) Toxicology Subcommittee Voted on Methods for Conducting Toxicity Tests lit Army Corps of Engineers 3 The New England Division of the Corps of Engineers held a symposium in De- cember to present the sum- mary of findings of the Disposal Area Monitoring System (DAMOS) project from the past 3-4 years. Topics included cap- ping work at disposal sites, tiered ap- proaches for monitoring potential impacts of dredged material, disposal site man- agement, and a review of field verification programs. The New England Division is currently assembling a monograph of capping operations at disposal sites. In addition, they are determining the feasibility of dis- posal options at the New Bedford Harbor Superfund site; disposal options include CDFs as well as confined aquatic disposal cells. NOAA The ASTM E47.03 Sediment Toxicology Subcommittee prepared several docu- ments designed to standardize approaches for collecting, processing, and test- ing the toxicity of sediments. The first two documents were approved by the sub- committee and await consideration by the full committee. The remaining docu- ments will also be submitted for review. To receive information on ASTM contact Chris Ingersoll at (314) 875-5399. Documents: 1.

Edward Long of NOAA is presently work- ing on a document that will 1) present de- scriptions of chemical contaminants measured as part of NOAA's National Status and Trends Program (NS&T), and 2) summary tables of toxicity threshold values for these chemicals in the sedi- ment, for various sediment quality assess- ment approaches and biological end- points. Chemical data at NS&T sites and a number of known "hotspots" will be compared to the threshold values. This work, which is expected to be finished by the er J of the year, will allow us to gage the toxicity of known chemical concentra- tions in the sediment. The Office of Marine Assessment of NOAA has recently produced two docu- ments relating to sediment contamination and their associated biological effects. The first document portrays geographical and temporal trends in concentrations of contaminants in sediment and biota, and the prevalence of selected measures of biological effects in San Francisco Bay. The second report evaluates candidate measures of biological effects for the NS&T Program. These reports are avail- able from Ed Long at (206) 526-6338. A list of ongoing research projects in ma- rine contaminated sediments is available through NOAA.
