Sec. 130.4  Water quality monitoring.

    (a) In accordance with section 106(e)(1), States must establish 
appropriate monitoring methods and procedures (including biological 
monitoring) necessary to compile and analyze data on the quality of 
waters of the United States and, to the extent practicable, ground-
waters. This requirement need not be met by Indian Tribes. However, any 
monitoring and/or analysis activities undertaken by a Tribe must be 
performed in accordance with EPA's quality assurance/quality control 
guidance.
    (b) The State's water monitoring program shall include collection 
and analysis of physical, chemical and biological data and quality 
assurance and control programs to assure scientifically valid data. The 
uses of these data include determining abatement and control priorities; 
developing and reviewing water quality standards, total maximum daily 
loads, wasteload allocations and load allocations; assessing compliance 
with National Pollutant Discharge Elimination System (NPDES) permits by 
dischargers; reporting information to the public through the section 
305(b) report and reviewing site-specific monitoring efforts.
