The next best option is Source Control . Treatment options have the highest construction and maintenance costs. The 5t" Term NPDES Permit will probably require development of various Implementation Plans to meet water quality standards. If drought conditions persist, water quality impacts may continue to decrease with a corresponding increase in the importance of ensuring water supply. Staff focus will need to adjust accordingly. Looking Ahead Reducing/Eliminating Trash is probably the Next Consented Effort. Working with our upstream Agencies to capture trash from San Diego Creek is an important way to improve water quality in the Bay. Pesticides In order to avoid future unknown issues and regulations (Bay sediments, Bio-accumulation, ...), watershed-wide education and efforts to control proper use of the new generation of pesticides will be needed. Trace Pollutants With over 200 City storms drains emptying into the Bay, reducing dry weather flows is the best way to reduce local water quality impacts at the end of these drains. 55 Quest *ions F SWP() F. r, r J k'S� I�IROK"�` Public Works Department Protecting and Providing Quality Public Improvements and Services 56
