Systematic Planning Process

All contaminated site cleanup projects should undergo systematic planning to help manage the inherent uncertainty in data collection. DEC's Contaminated Sites Program encourages contractors to pursue systematic planning training, including basic statistical concepts, to streamline and document the planning process and to provide a defensible sampling approach. Work plans developed through systematic planning will help CSP correctly evaluate various sampling designs and make real-time sampling design changes.

EPA's Systematic Planning Guidance (This document is an expanded version of the August 2000, Guidance for the Data Quality Objectives Process and includes both decision making and estimation using the Data Quality Objectives (DQO) Process.)

Cleanup Level Guidance -- Adopted by Reference

ADEC recommends referring to this guidance in evaluating PCB cleanup and disposal options at contaminated sites. Coordination with both ADEC and EPA's Region 10 PCBs Coordinator is required for all contaminated sites with PCB concentrations greater than 1 mg/kg (ppm).

Region X PCBs Coordinator: Daniel Duncan, EPA Region 10, Office of Compliance & Enforcement, 206-553-6693, 206-553-1775 fax

MULTI INCREMENT® Sampling:
Under the correct circumstances and when properly conducted, multi-increment sampling can produce a more accurate estimate of the mean contaminant concentration and at a lower cost than discrete sampling. Therefore, CSP endorses the use of multi-increment sampling as part of the cleanup process to help ensure protection of human health and the environment. CSP encourages those interested in utilizing this approach to pursue method-specific training and to coordinate with their DEC CSP Project Manager during work plan development.

Army Corps of Engineers Interim guidance for the Implementation of Incremental Sampling of Soil for the Military Munitions Response Program. The State of Alaska guidance requirements still need to be followed. The Corps' interim guidance provides helpful information on the necessity of up-front planning and agreement on data quality objectives and sampling unit determination.

Site Closure Memorandum DEC decides when sites may be closed under 18 AAC 75.380 and 18 AAC 78.276, including the use of institutional controls. Although this memo identifies how DEC staff will make closure determinations, we are making it available to anyone who may have an interest in site closure decision-making. This memorandum replaces the "Site Closure Policy and Procedures, Draft Final" previously posted on this page.
