Page 14 development. In addition, the existing pipe is 6”-diameter, whereas the proposed upstream network is 8”-diameter. The City discourages constrictions in the network that could lead to surcharged flow or obstructions. A network analysis must therefore confirm that the 6”-diameter pipe functions without surcharge, or the existing pipe will require upsizing to 8”-diameter. As an alternative to the proposed sanitary sewer connection through 2112 Tanager Court, the City operates an 8”-diameter public sanitary sewer main within Santa Rita Road across the property frontage. Connection to this existing network is allowed pending verification of its condition and capacity. (Address this condition prior to issuance of any Building Permits) 77.POLLUTANT REDUCTION IN STORM WATER. At no time during construction of the project shall pollutants be allowed to enter, clog, or contaminate storm drain pipe networks or open stormwater channels in violation of Pleasanton Municipal Code §9.14.080 et seq. The applicant shall contain all trash and debris for proper disposal to authorized landfills or recyclers. Erosion control features shall be deployed during the rainy season that extends from October 1st to April 15th each year, or any time rain is forecast outside of this period. Best Management Practices (BMPs) shall be strictly followed. Street sweepers must be employed if soil or debris is tracked onto the public roads from vehicles exiting the site. Standard BMPs are available from the California Stormwater Quality Association (CASQA), the United States Environmental Protection Agency (EPA), Caltrans, and others. Notes and/or illustrations shall be added to the plans that describe the BMPs to be utilized during construction. The use of manufactured erosion control woven blankets and straw wattles that utilize plastic monofilament netting is specifically prohibited. (Address this condition during construction) 78.MUNICIPAL REGIONAL PERMIT. Because the project creates and/or replaces more than 5,000 square feet (0.23 acres) of impervious surface, it is considered a Regulated Project according to Provision C.3.b of the Municipal Regional Stormwater NPDES Permit that regulates stormwater runoff in Alameda County. The Alameda Countywide Clean Water Program developed a C.3 Guidance Manual to assist applicants in addressing these regulations. The Guidance Manual is available for download at: https://www.cleanwaterprogram.org/businesses/development.html Regulated projects must include stormwater treatment measures in the site design to remove pollutants from stormwater upstream of any connection to the City’s or Alameda County’s stormwater conveyance networks. In addition, regulated projects must be subject to a Stormwater Treatment Measure Maintenance Agreement between the City and property owner to assure long-term maintenance of the installed measures. The City will provide a template agreement. Once executed, the agreement must be recorded against the property. (Address this condition prior to issuance of any Building Permits) 79.CONSTRUCTION GENERAL PERMIT. The project will be subject to a Construction General Permit according to the National Pollutant Discharge Elimination System (NPDES) General Permit No. CAS000002. The general permit is applicable to development sites that disturb one or more acres of land surface. The applicant will be required to register the project with the State Water Board’s Stormwater Multi-Application and Report Tracking System (SMARTS) website. A Qualified SWPPP Developer (QSD) and a Qualified SWPPP Practitioner (QSP) must be responsible for permit compliance. The SMARTS system will generate a Waste Dischargers Identification (WDID) number, which must be printed on the grading and/or erosion control plans.(Address this condition prior to issuance of any Building Permits)
