New York State Water Quality Standards (WQS)

DEC code (law) for NYS WQS

This document includes information about New York State water quality laws. Try to integrate these classifications and standards into your comments. ( Download a pdf of this file here.)

All streams are classified for their best uses (fishing, swimming, drinking water, etc.). The DEC then applies standards (and guidance) to protect those uses.

The DEC refers to surface waters (rivers, streams, etc.) by their alphabetical code (AA, B, T, etc.). Each has its own level of protection. So when you discuss a stream, mention its classification, and then describe how building the pipeline would degrade its best use.

You can also describe how building the pipeline would violate narrative water quality standards for different classes of streams. These standards are in § 703.
