In the case of emergency, call JEFF BETHEL at Cell Phone# (949) 294-5333. 2. Sediment from areas disturbed by construction shall be retained on site using structural controls to the maximum extent practicable. 3. Stockpiles of soil shall be properly contained to minimize sediment transport from the site to streets, drainage facilities or adjacent properties via runoff, vehicle tacking, or wind. 4. Appropriate BMP’ for construction-related materials, wastes, spills shall be implemented to minimize transport from the site to streets, drainage facilities, or adjoining properties by wind or runoff. 5. Runoff from equipment and vehicle washing shall be contained at construction sites unless treated to reduce or remove sediment and other pollutants. 6. All construction contractor and subcontractor personnel are to be made aware or the required best management practices and good housekeeping measures for the project site and any associated construction staging areas. 7. At the end of each day of construction activity all construction debris and waste materials shall be collected and properly disposed in trash or recycle bins. 8. Construction sites shall be maintained in such a condition that an anticipated storm does not carry wastes or pollutants off the site. Discharges of material other than stormwater only when necessary for performance and completion of construction practices and where they do not: cause or contribute to a violation of any water quality standard; cause or threaten to cause pollution, contamination, or nuisance; or contain a hazardous substance in a quantity reportable under Federal Regulations 40 CFR Parts 117 and 302. 9. Potential pollutants include but are not limited to: solid or liquid chemical spills; wastes from paints, stains, sealants, glues, limes, pesticides, herbicides, wood preservatives and solvents; asbestos fibers, paint flakes or stucco fragments; fuels, oils, lubricants, and hydraulic, radiator or battery fluids; fertilizers, vehicle/equipment wash water and concrete wash water; concrete, detergent or floatable wastes; wastes from any engine/equipment steam cleaning or chemical degreasing and superchlorinated potable water line flushing. During construction, permittee shall dispose of such materials in a specified and controlled temporary area onsite, physically separated from potential stormwater runoff, with ultimate disposal in accordance with local, state and federal requirements. 10. Dewatering of contaminated groundwater, or discharging contaminated soils via surface erosion is prohibited. Dewatering of non-contaminated groundwater requires a National Pollutant Discharge Elimination System Permit from the respective State Regional Water Quality Board. 11. Graded areas on the permitted area perimeter must drain away from the face of slopes at the conclusion of each working day. Drainage is to be directed toward desiliting facilities. 12. The permittee and contractor shall be responsible and shall take necessary precautions to prevent public trespass onto areas where impounded water creates a hazardous condition. 13. The permittee and contractor shall inspect the erosion control work and insure that the work is in accordance with the approved plans. 14. The permittee shall notify all general contractors, subcontractors, material suppliers, lessees, and property owners; that dumping of chemicals into the storm drain system or the watershed is prohibited. 15. Equipment and workers for emergency work shall be made available at all times during the rainy season. Necessary materials shall be available on site and stockpiled at convenient locations to facilitate rapid construction of temporary devices when rain is imminent. 16. All removable erosion protective devices shall be in place at the end of each working day when the 5-Day Rain Probability Forecast exceeds 40%. 17. Sediments from areas disturbed by construction shall be retained on site using an effective combination of erosion and sediment controls to the maximum extent practicable, and stockpiles of soil shall be properly contained to minimize sediment transport from the site to streets, drainage facilities of adjacent properties via runoff, vehicle tracking, or wind. 18. Appropriate BMP’s for construction-related materials, wastes, spills or residues shall be implemented and retained on site to minimize transport from the site to streets, drainage facilities, or adjoining property by wind or runoff.

DRY SEASON REQUIREMENTS (MAY-SEPTEMBER) 1. WIND EROSION BMPS (DUST CONTROL) SHALL BE IMPLEMENTED 2. SEDIMENT CONTROL BMPS SHALL BE INSTALLED AND MAINTAINED AT ALL OPERATIONAL STORM DRAIN INLETS. 3. BMPS TO CONTROL OFF-SITE SEDIMENT TRACKS SHALL BE IMPLEMENTED AND MAINTAINED 4. APPROPRIATE WASTE MANAGEMENT AND MATERIALS POLLUTION CONTROL BMPS SHALL BE IMPLEMENTED TO PREVENT THE CONTAMINATION OF STORM WATER BY WASTES AND CONSTRUCTION MATERIALS 5. APPROPRIATE NON-STORM WATER BMPS SHALL BE IMPLEMENTED TO PREVENT THE CONTAMINATION OF STORM WATER FROM CONSTRUCTION ACTIVITIES. 6. THERE SHALL BE A "WEATHER TRIGGERED" ACTION PLAN AND THE ABILITY TO DEPLOY STANDBY SEDIMENT CONTROL BMPS AS NEEDED TO COMPLETELY PROTECT THE EXPOSED PORTIONS OF THE SITE WITHIN 48 HOURS OF A PREDICTED STORM EVENT (A PREDICTED STORM IS DEFINED AS A FORECASTED , 50% CHANCE OF RAIN. 7. SUFFICIENT MATERIALS NEEDED TO INSTALL STANDBY SEDIMENT CONTROL BMPS (AT THE SITE PERIMETER. SITE SLOPES AND OPERATIONAL INLETS WITHIN THE SITE) NECESSARY TO PREVENT SEDIMENT DISCHARGES FROM EXPOSED PORTIONS OF THE SITE SHALL BE STORED ON SITE. AREAS THAT HAVE ALREADY BEEN PROTECTED FROM EROSION USING PHYSICAL STABILIZATION OR ESTABLISHED VEGETATION STABILIZATION BMPS AS DESCRIBED IN ITEM H ARE NOT CONSIDERED TO BE EXPOSED FOR PURPOSES OF THIS REQUIREMENT. 8. DEPLOYMENT OF PERMANENT EROSION CONTROL BMPS (PHYSICAL OR VEGETATION SHOULD COMMENCE AS SOON AS PRACTICAL ON SLOPES THAT ARE COMPLETED FOR ANY PORTION OF THE SITE). STANDBY BMP MATERIALS SHOULD NOT BE RELIED UPON TO PREVENT EROSION OF SLOPES THAT HAVE BEEN COMPLETED. WET SEASON REQUIREMENTS (OCTOBER-APRIL) 1. WHERE APPROPRIATE SEDIMENT CONTROL BMPS SHALL BE IMPLEMENTED AT THE SITE PERIMETER, AT ALL OPERATIONAL STORM DRAIN INLETS, AND AT ALL NON-ACTIVE SLOPES, TO PROVIDE SUFFICIENT PROTECTION FOR STORMS LIKELY TO OCCUR DURING THE RAINY SEASON. 2. ADEQUATE PHYSICAL OR VEGETATION EROSION CONTROL BMPS (TEMPORARY OR PERMANENT) SHALL BE INSTALLED AND ESTABLISHED FOR ALL COMPLETED SLOPES PRIOR TO THE START OF THE RAINY SEASON. THESE BMPS MUST BE MAINTAINED THROUGHOUT THE RAINY SEASON. IF A SELECTED BMPS FAILS, IT MUST BE REPAIRED AND IMPROVED, OR REPLACED WITH AN ACCEPTABLE ALTERNATE AS SOON AS IT IS SAFE TO DO SO. THE FAILURE OF A BMP MAY INDICATE THAT THE BMP, AS INSTALLED, WAS NOT ADEQUATE FOR THE CIRCUMSTANCES IN SHICH IT WAS USED. REPAIRS OR REPLACEMENTS MUST RESULT IN A MORE ROBUST BMP, OR ADDITIONAL BMPS SHOULD BE INSTALLED TO PROVIDE ADEQUATE PROTECTION 3. THE AMOUNT OF EXPOSED SOIL ALLOWED AT ONE TIME SHALL NOT EXCEED THAT WHICH CAN BE ADEQUATELY PROTECTED BY DEPLOYING STANDBY EROSION CONTROL AND SEDIMENT CONTROL BMPS PRIOR TO A PREDICTED RAIN STORM. 4. A DISTURBED AREA THAT IS NOT COMPLETED OR THAT IS NOT BEING ACTIVELY GRADED (NON-ACTIVE AREA) SHALL BE FULLY PROTECTED FROM EROSION WITH TEMPORARY OR PERMANENT BMPS (EROSION AND SEDIMENT CONTROL). THE ABILITY TO DEPLOY STANDBY BMP MATERIALS IS NOT SUFFICIENT FOR THESE AREAS. EROSION AND SEDIMENT CONTROL BMPS MUST ACTUALLY BE DEPLOYED. THIS INCLUDES ALL BUILDING PADS, UNFINISHED ROADS, AND SLOPES. 5. SUFFICIENT MATERIALS NEEDED TO INSTALL STANDBY EROSION AND SEDIMENT BMPS NECESSARY TO COMPLETELY PROTECT THE EXPOSED PORTIONS OF THE SITE FROM EROSION AND TO PREVENT SEDIMENT DISCHARGES SHALL BE STORED ON-SITE. AREAS THAT HAVE ALREADY BEEN PROTECTED FROM EROSION USING PERMANENT PHYSICAL STABILIZATION OR ESTABLISHED VEGETATION STABILIZATION BMPS ARE NOT CONSIDERED TO BE EXPOSED FOR PURPOSES OF THIS REQUIREMENT.
