Pennsylvania Code › Title 25 - ENVIRONMENTAL PROTECTION › Part I - Department of Environmental Protection › Subpart C - Protection of Natural Resources › Article II - Water Resources › Chapter 93 - WATER QUALITY STANDARDS › WATER QUALITY CRITERIA › Section 93.8e - Special criteria for the Great Lakes System

Current through Register Vol. 54, No. 28, July 13, 2024
(a)
Special criteria
. The
						special provisions in this section apply for the Great Lakes System, which
						includes the streams, rivers, lakes and other bodies of surface water within
						the drainage basin of the Great Lakes in this Commonwealth.
(b)
Water quality criteria for the
						Great Lakes System
. Human health and aquatic life criteria for the
						Great Lakes System are contained in Table 6 (relating to Great Lakes aquatic
						life and human health criteria). For any pollutant not listed in the table,
						criteria in Table 5 may be used to protect existing and designated uses, or
						criteria will be developed by the Department, as needed, in accordance with
						this chapter and §
												16.61 (relating to special
						provisions for the Great Lakes System).

Acronyms and Footnotes to Table 6
* Indicates dissolved metal criterion; others are total
						  recoverable metals. Each listed dissolved criterion in Table 6 is equal to the
						  corresponding total recoverable criterion before rounding (from the EPA
						  National Ambient Water Quality Criteria Documents) multiplied by the conversion
						  factor (from the Conversion Factors Table); a criterion that is expressed as a
						  hardness (H)-based equation is shown in Table 6 as the conversion factor
						  (listed) multiplied by the hardness criterion equation; an example criterion at
						  hardness=100mg/L is included.
CAS-Chemical Abstract Service number
CRL-Cancer risk level at 1 x
						  10-6
H-Threshold effect human health criterion; incorporates
						  additional uncertainty factor for some Group C carcinogens.
ln [H]-Natural Logarithm of the Hardness of stream as

Wildlife criteria
.
						Wildlife criteria will be developed for the bioaccumulative chemicals of
						concern (BCCs) in the Great Lakes System using methodologies contained in the
						Great Lakes guidance in 40 CFR Part 132 , Appendix D (relating to Great Lakes
						Water Quality Initiative methodology for the development of wildlife criteria).
