SRA-NE and LSP Association held a joint seminar on Tuesday, April 7, 2015 at the Westin Waltham Hotel. The seminar featured two presentations, one from Paul McManus, LSP, President, Eco-tec, Inc. and another from Stephen Clough, Ph.D., Senior Toxicologist, Haley & Aldrich, Inc.
Presentation 1 Abstract: The Massachusetts Contingency Plan (MCP) requires that site-related constituents not pose a significant risk to environmental receptors, which are assessed via a Method 3 risk assessment under Chapter 9. Most LSPs are familiar with the risk assessment process for OHM in soil and groundwater, which are often screened using Method 1 Risk Assessment guidelines. Method 1 Standards, however, do not exist for the characterization of ecological risk, i.e., estimating the hazard that contaminated surface water or sediment may pose to fish and wildlife. Chapter 9 of the MCP provides a two-tiered framework for environmental risk assessment (Stage I and/or Stage II “Environmental Risk Characterization”). This presentation focuses on environmental risk characterization under the MCP. Over the course of 35 minutes, Mr. McManus will provide: an introduction to the environmental risk assessment process under the MCP, information on identifying environmental pathways and receptors, an explanation of the distinction between soil and sediment (often an area of confusion by LSPs), and considerations for ecological sampling. He will also briefly discuss recent changes to the Massachusetts Wetland Regulations regarding the jurisdiction of stormwater basins.
Presentation 2 Abstract: Dr. Clough’s 20-minute presentation will cover several MCP case studies that highlight the value of the consideration of bioavailability and how sediment toxicity tests (specifically, the Sediment Quality Triad approach) can, more often than not, save time, money and effort.
