Integrated Report and Total Maximum Daily Loads
Clean Water Act 303(d) List
On August 16, 2018, the U.S. Environmental Protection Agency (EPA) approved the 2018 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 2018 303(d) List of Impaired Waters (represented by those water bodies assigned to categories 4 and 5 in Chapter 3, 2018 §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.
NOTICE OF PUBLIC COMMENT PERIOD-TOTAL MAXIMUM DAILY LOADS (TMDLs) FOR THE WAIKELE WATERSHED, ISLAND OF OAHU, HAWAII
The State of Hawaii, Department of Health (DOH) requests public comments on the proposed total maximum daily loads (TMDLs) of turbidity, sediment, and nutrients for the Waikele Watershed, Oahu, under §303(d) and §303(e) of the Federal Clean Water Act, 33 U.S. Code §1313(d) and §1313(e), and 40 CFR §130.7 and §130.5. The draft document, entitled “Turbidity, Sediment and Nutrient Total Maximum Daily Loads (TMDLs) for the Waikele Watershed, Oahu, Hawaii” identifies point and nonpoint sources of water pollution, specifies the reductions necessary to meet water quality standards, and provides waste load and load allocations for each identified source. The proposed decision document will affect water pollution control permits and provide guidance for other planning and regulatory approvals within the Waikele watershed.
A copy of the draft document can be obtained by contacting the Clean Water Branch (CWB) at (808) 586-4309, CleanWaterBranch@doh.hawaii.gov, or by downloading from the CWB website at http://health.hawaii.gov/cwb/clean-water-branch-home-page/integrated-report-and-total-maximum-daily-loads/. The draft document will also be available for public review Monday through Friday between 7:45 am and 4:30 pm in the CWB office, and District Health Offices (DHOs) on Hawaii, Kauai, and Maui:
