Integrated Report and Total Maximum Daily Loads

Marine Water Quality Assessment Methodology for the 2016 Integrated Report

The CWB Monitoring and Analysis Section has developed an implementation document for the 2016 IR that describes 1) the challenges associated with changing scopes of assessment in previous IRs; 2) the assessment methodology used in the 2014 IR; 3) the change from variable scopes of assessment to clearly defined decision units and 4) the application of the CWB branch standardized assessment methodology for State marine waters for IR implementation.

Clean Water Act 303(d) List

On October 22, 2014, the U.S. Environmental Protection Agency (EPA) approved the 2014 State of Hawaii Water Quality Monitoring and Assessment Report.  This report provides a single, integrated submittal for fulfilling federal requirements under Sections (§) 303(d) and 305(b) of the Clean Water Act.  With this approval, the 2014 303(d) List of Impaired Waters (represented by those water bodies assigned to categories 4 and 5 in Chapter 3, 2014 §303(d) and §305(b) Water Body Assessments for Hawaii), is now in effect.

The Total Maximum Daily Load (TMDL) Process

The TMDL process serves as a roadmap for water body restoration by focusing on improving water quality in impaired surface waters identified in the biennial State of Hawaii Water Quality Monitoring and Assessment Report. TMDLs identify sources of pollution within a watershed and determine pollutant load reductions required for a water body to meet water quality standards. The TMDL process is a vital component of implementing water quality improvement projects under Clean Water Act Section 319(h) grants, administered by the Department of Health, Polluted Runoff Control Program.

Additional information on TMDLs can be found on the U.S.Environmental Protection Agency TMDL website.
