Recommended Conditions of Approval October 21, 2019 PLN17-0034 311 MacArthur Blvd. Page 5 of 12 No. R2-2015-0049, NPDES Permit No. CAS612008, adopted 11/19/2015). Stormwater treatment measures must be constructed to provide the required treatment of storm runoff prior to entering the public storm drain system. 19. O&M Agreement. The applicant shall submit a detailed Operations and Maintenance agreement in accordance with MRP section C.3.h. The O&M agreement shall be required prior to Grading Permit issuance. 20. Storm Water Pollution Measures. The applicant shall reduce storm water pollution by implementing the following pollution source control measures: 20.1. Structures shall be designed to discourage the occurrence and entry of pests into buildings, thus minimizing the need for pesticides. The trash area shall be separated from the rest of the building by concrete or masonry walls so that pests that gain access to the area are less likely to access the rest of the building. 20.2. All storm drains shall be marked “NO DUMPING, DRAINS TO BAY”. 20.3. All on-site storm drains shall be inspected and, if necessary, cleaned at least twice a year immediately prior to the rainy season. 20.4. Sidewalks and parking lots shall be swept regularly to minimize the accumulation of litter and debris. Steam cleaning or low volume pressure washing may be performed only after pre-cleaning using dry methods, spot cleaning and recovery in stained areas and removal of all mobile pollutants. 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. 20.5. Interior floor drains (if any) shall not be connected to the storm drain system. 20.6. Air conditioning condensate shall be directed to landscaped areas. Any air conditioning condensate that discharges to land without flowing to a storm drain may be subject to the requirements of the State Water Resources Control Board’s (SWRCB) Statewide General Waste Discharge Requirements (WDRs) for Discharges to Land with a Low Threat to Water Quality. 20.7. Landscaping shall be designed to minimize irrigation and runoff, promote surface infiltration where appropriate, and minimize the use of fertilizers and pesticides that can contribute to storm water pollution. 20.8. Where feasible, landscaping shall be designed and operated to treat storm water runoff by incorporating elements that collect, detain, and infiltrate runoff. In areas that provide detention of water, plans that are tolerant of saturated soil conditions and prolonged exposure to water shall be specified. 20.9. Plant materials selected shall be appropriate to site specific characteristics such as soil type, topography, climate, amount and timing of sunlight, prevailing winds, rainfall, air movement, patterns of land use, ecological consistency and plant interactions to ensure successful establishment. 20.10. Selection of the plants that will require minimal pesticide use. 20.11. Irrigation shall be appropriate to the water requirements of the selected plants.
