LWA’s watershed management and TMDL (Total Maximum Daily Load) assistance includes development of TMDLs for nutrients, toxicity, organophosphate and organochlorine pesticides, metals, salts and bacteria as part of a coordinated stakeholder process. As part of the TMDL development, LWA conducts a review of applicable water quality standards (including the development of site-specific criteria), beneficial uses, and data used to develop the 303(d) listings. LWA develops technical work to support the TMDL development, provides support on policy and regulatory issues, and coordinates stakeholder and regulatory agency participation and communication.
