<br />State Salinity Control Activities <br /> <br />~ Important components of the plan of implementation for <br />CJl <br />CJl salinity control are the Basin states' activities associated <br />o <br /> <br />with the control of total dissolved solids through the NPDES <br /> <br />Permit program and the water quality management plans. All <br /> <br />states have adopted the 1977 Forum Policy for Implementation <br />of the Colorado River Basin Salinity Standards through the <br />NPDES Permit Program. A copy of the policy can be found in <br /> <br />the 1978 Revision of the Water Quality Standards for <br /> <br />Salinity. <br /> <br />In October 1982, the Basin states adopted the <br /> <br />"Intercepted Groundwater policy for Implementation of the <br />Colorado River Salinity Standards Through the NPDES Permit <br />program." A copy of that policy can be found in the 1984 <br /> <br />Review. <br /> <br />During the period of this report, the status of <br /> <br />implementation of the NPDES permits and the water quality <br /> <br />management plans in each of the states was as follows: <br /> <br />Arizona <br /> <br />NPDES Permits - Authority for issuing NPDES permits has <br /> <br /> <br />not been delegated to the state and still resides in the <br /> <br />Region IX office of EPA. Arizona is currently operating <br /> <br /> <br />under an "interim" plan in which the state prepares the <br /> <br />permit, solicits public comments and involvement, and <br /> <br />forwards the final draft to EPA for signatures and issuance. <br /> <br />Arizo'na, in drafting NPDES permits for industries <br /> <br />throughout the Colorado River Basin within the state above <br /> <br />Imperial Dam, follows the Forum's policy regarding salinity <br /> <br />-23- <br /> <br />l, <br />
