Section 93.9 - Designated water uses and water quality criteria
(a) The tables in §§ 93.9a-93.9z display designated water uses and water quality criteria in addition to the water uses and criteria specified in Tables 2 and 3. Designated uses shall be protected in accordance with Chapters 95 and 96 (relating to wastewater treatment requirements; and water quality standards implementation) and any other applicable State and Federal laws and regulations. The tables also indicate specific exceptions to Tables 2 and 3 on a stream-by-stream or segment-by-segment basis by the words "add" or "delete" followed by the appropriate symbols described elsewhere in this chapter. The county column in §§ 93.9a-93.9z indicates the county in which the mouth of the stream or the downstream limit of the zone described for that entry is located. Abbreviations used in the Stream and the "Zone" columns are as follows:

FAS-Federal Aid Secondary Highway

I-Interstate Highway

LR-Pennsylvania Legislative Route

RM-River Mile; river miles are used to indicate the distance from a point on the waterbody to its mouth and are based on the DEP's River Mile Index

SR-Pennsylvania State Route

T-Township Road

UNT-Unnamed Tributaries

US-United States Federal Route

(b) When appropriate, "Exceptions to Specific Criteria" provide reference to the Delaware River Basin Commission (DRBC) water quality regulations, Orsanco (Ohio River Valley Water Sanitation Commission) pollution control standards and the Great Lakes Water Quality Agreement (GLWQA) which specify the criteria that apply if a water quality standard is more stringent than those in this title. The applicable criteria can be obtained from the following:
