FASTAC Decision Tree


FASTAC Decision Tree for Analytical Services

The following recommended decision tree for analytical services was distributed to the
Regions in a memorandum dated November 17, 1998, and signed by Tim Fields, Office of Solid Waste and Emergency Response, and Betty Bailey, Office of Acquisition Management:

  • Tier 1 – EPA Regional Laboratory and ESAT Contract
  • Tier 2 – National Analytical Services Contracts (i.e., CLP)
  • Tier 3 – Region Specific Analytical Services Contract
  • Tier 4 - Analytical Services IAGs and Field Contracts/Subcontracts
Region 6 Implementation of Decision Tree

In Region 6, the hierarchy currently consists of Tiers 1, 2, and 4 only. The Regional Sample Control Center (R6SCC) is located in the Environmental Services Branch (ESB) Laboratory in Houston, Texas. The ESB Laboratory is the Region 6 Laboratory. The R6SCC is the group responsible for scheduling samples through the Region 6 ESB Laboratory, prepared by the Environmental Services Assistance Team (ESAT), hereafter refered to as Region 6 ESB Laboratory/ESAT , or the National Contract Laboratory Program (CLP).

To ensure that the users know what analytical services are available through the Region 6 ESB Laboratory/ESAT and the CLP, tables of all current analytical services are posted on the internet at the Region 6 ESB Laboratory web page. The user contacts the R6SCC or consults/reviews the analytical services capabilities to determine whether his/her samples can be processed by the Regional laboratory/ESAT or CLP.

If the user determines, after reviewing the analytical capabilities , that the samples can be
processed through the Region 6 laboratory/ ESAT or the CLP, the user must contact Christy Warren, of the Region 6 Sample Control Center. If the user determines that the samples cannot go through the Region 6 laboratory/ESAT or the CLP, the user will utilize the appropriate field contract. If the user is unsure of the most appropriate analytical service to use, the R6SCC may be contacted for guidance.

Of the analytical services requests that go to the R6SCC, the laboratory is given the right of first refusal. The R6SCC determines if the regional laboratory has the capability and capacity to analyze the samples. Assuming the laboratory has the capability and capacity, the R6SCC will accept the samples. If the laboratory declines the samples, the R6SCC determines if the samples are CLP appropriate. If CLP appropriate, the R6SCC notifies the user and submits the analytical request forms to the CLP RSCC. If samples can be analyzed by ESAT, the R6SCC in coordination with laboratory team leaders determines which samples will be analyzed, and ESAT is notified. If samples cannot be processed through the Region 6 ESC Laboratory/ESAT or CLP, the user is notified and he/she will proceed with the field contracts option.

To document and track the samples not processed through the R6SCC (Special Analytical Services [SAS]), field contractors are required to provide analytical services information for Non-CLP work to the Analytical Services Tracking System (ANSETS).  There are three major methods of submitting ANSETS data. Links to these methods, including a description and instructions are provided at http://www.epa.gov/superfund/programs/clp/ansets.htm
