Total Waste Load Allocation:	.0058	Total Load Allocation:	.831
Explicit Margin Of Safety:	0 LBS/DAY	Implicit Margin Of Safety:	N
Units for Total Waste Load Allocation and Total Load Allocation:	LBS/DAY	TMDL Pollutant Source Type:	Point/Nonpoint Source
TMDL End Point:	THE LOAD CAPACITY IS DEFINED BY THE NUMERIC WATER QUALITY CRITERION FOR COPPER WHICH IS HARDNESS DEPENDENT. THE ENDPOINT IS FOR TOTAL COPPER CONCENTRATIONS TO REMAIN BELOW THE ACUTE COPPER CRITERION (18.5 UG/L). THIS SHOULD BE ADEQUATELY PROTECTIVE OF CHRONIC TOXICITY AS WELL. THE TMDL WAS DEVELOPED USING THE ACUTE CRITERION FOR COPPER AT THE 90% LOWER CONFIDENCE LIMIT TOTAL HARDNESS CONCENTRATION (134.5 MG/L CACO3). THIS RESULTS IN 82% REDUCTION IN COPPER LOADING AND SHOULD ATTAIN WQS.
