facility is adequate to detain and treat stormwater from this site prior to issuance of building permits for this project. The bio-ponds shown will not be sufficient to treat stormwater from such a large area, so additional treatment measures should be included or the size of these bio-ponds shall be increased. For more information, please see the C.3 Stormwater Technical Guidance Handbook, which is available at: httpJ/www.eoainc.com/download/ACCWP Tech guidance-black text.pdf R. Since this project disturbs over one acre of land, a State general Construction Activity Permit must be obtained.

The revised National Pollutant Discharge Elimination System (NPDES) Permit, issued by the San Francisco Regional Water Quality Control Board in February 2003, imposed new requirements on developers and local agencies. In addition to requiring developers to install stormwater treatment measures, developers also have to sign a Stormwater Treatment Measures Maintenance Agreement for the maintenance of the treatment measures in perpetuity. The Agreement should detail the proposed maintenance activities and the intervals at which they will be conducted for each stormwater treatment measure included in this project. A copy of the Agreement shall be included with the building permit submittal. T. Runoff from trash enclosures, recycling areas, or similar facilities shall not discharge to the storm drain system. Trash enclosure areas shall be covered and designed to avoid run-on to the trash enclosure area. Any drains installed in or beneath dumpsters shall be connected to a grease removal device and/or treatment devices prior to discharging to the sanitary sewer. U. Sidewalks and parking lots shall be swept regularly to minimize the accumulation of litter and debris. Debris resulting from pressure washing shall be trapped and collected to prevent entry into the storm drain system. Wash water containing any soap, cleaning agent or degreaser shall not be discharged to the storm drain and shall be collected and discharged to the sanitary sewer or collected and treated prior to being lawfully disposed. V. All on-site storm drains must be cleaned or inspected and, if necessary, cleaned at least ance a year immediately prior to the rainy season. Additional cleaning maybe required by the City Engineer. W, Roof drains shall discharge to an unpaved area wherever practicable. X.
