<br />WQ-3 Prior to the issuance of grading permits the project developer shall provide two <br />copies of the Water Quality Management Plan that include the following: <br /> <br />I. Site Assessment <br />2. Site Design BMPs <br />3. Applicable Routine Source Control BMPs <br />4. Selection and sizing of the Treatment Control BMPs <br />5. Mechanisms by which funding for long-tenn operation and maintenance <br />of Structural BMPs will be provided <br />6. Operation and Maintenance Plan to describe the long-term operation and <br />maintenance requirements of all applicable Structural BMPs, and to <br />identifY the entity in charge of implementation <br /> <br />Comment DI-C <br /> <br />The submitted comment requests that the DEIR identifY receiving waters that may <br />receive runoff from the project site. <br /> <br />Page 22 of the DEIR identifies that runofffrom the project site would drain by sheet flow <br />along Farmers Drive and Orange Road before entering into the local storm drain system. <br />The local storm drain system would convey flows into Santiago Creek and then to the <br />Santa Ana River before ultimately discharging into the Pacific Ocean. <br /> <br />Comment DI-D <br /> <br />The submitted comment requests that the DEIR identifY the sensitivity of receiving <br />waters. <br /> <br />Page 22 ofthe DEIR identifies that the mouth of the Santa Ana River at the Pacific <br />Ocean is an impaired water body. <br /> <br />Comment DI-E <br /> <br />The submitted comment requests that the DEIR characterize the potential water quality <br />impacts associated with the proposed project. <br /> <br />Page 23 of the DEIR identifies that the primary concern for water quality pollutants <br />associated with the operation of the proposed project would be from urban runoff. Urban <br />runoff is defined as runoff that occurs during periods that are not usually associated with <br />rainfall, and are most commonly produced from landscaping irrigation, leaking pipes, and <br />water used to wash off surfaces tributary to the street. Since urban runoff originates in the <br />street, it commonly contains many common pollutants found in streets such as oil and <br />grease and sediment. Additionally, adverse water quality impacts could occur from rain <br />events when sediment, grease and oil on roadways and parking lots are flushed into the <br />local storm drain system. Additionally, the DEIR identifies that during construction <br /> <br />75~46 <br />
