• new data collection should be necessary because this is not believed to be timely or cost effective at this point in the screening process.
• The criteria should address areas that are generally large enough to appear as areas rather than points on the map and will therefore be more meaningful by reducing the area to be considered in subsequent steps.

Given these limitations, the Siting Commission selected only 5 of the 17 exclusionary criteria for the SES step. These criteria were applicable to both of the disposal methods under consideration: aboveground or belowground disposal and underground mine disposal. The specific criteria and their regulatory bases are described in Table I.1. Details of their implementation are discussed below. The Siting Commission used maps of 1:250,000 scale¹ in this screening step.

Exclude all areas above the Long Island Aquifer, any primary water supply aquifer, or principal aquifer designated by the Department of Environmental Conservation (DEC).²

Within this criterion, primary public water supply aquifers were defined by the DEC as "highly productive aquifers presently being utilized as sources of water by major municipal water supply systems." Principal aquifers were defined as "aquifers known to be highly productive or whose geology suggests abundant potential water supply, but which are not intensively used as sources of water supply by major municipal systems at the present time" (emphasis added).

The locations of the Long Island Aquifer and 18 primary aquifers were relatively well defined, but because only a few of the principal
