The NACOG area-wide 208 Plan is in <br />the update process which was last updated in 1993. <br /> <br />The Western Arizona Council of Governments (W ACOG) had similar responsibilities for <br />Mohave, La Paz, and Yuma Counties until they de-designated from the program in 1993.

The Act established a new Department of Environmental Quality on July 1, 1987. The <br />water quality staff of the Department is developing programs to protect the quality of both surface <br />and ground water, including point source and nonpoint source management, permitting; and <br />pesticides management. The State Nonpoint Source Water Quality Assessment and Management <br />Plan reports have been approved by EPA and demonstration projects are being evaluated. The <br />State Nonpoint Source Management Plan provides for consistency reviews in accordance with <br />Section 319(k) of the federal Clean Water Act. Consistency reviews provide an effective <br />mechanism for states to ensure proposed projects and programs contribute to improved water <br />quality management. Categories of projects and programs related to salinity control include <br />irrigation systems, salinity control projects impoundments, diversion and rangeland management. <br />Also, a comprehensive Aquifer Protection Permit (APP) program, established in 1986 and <br />implemented by rule in 1989, requires permits for most activities that discharge, including point <br />source discharges to Arizona's surface water bodies. <br /> <br />California <br /> <br />NPDRli; Permit~ <br /> <br />The California Regional Water Quality Control Board, Colorado River Basin Region <br />(Regional Board), issues the NPDES permits for navigable waters and Waste Discharge <br />Requirements for land discharges within the Colorado River drainage portion of the state.
