The comments below were generated from this project's City of Everett Industrial Pretreatment Reviewer. All questions shall be routed through this project's <br />Public Works Reviewer Thad Newport with City of Everett Permit Services (TNewport@everettwa.gov). <br /># <br />Document <br />Sht/Pg <br />Reviewer's Comment <br />Designer's Response <br />Initials <br />canopy is not required to meet the water quality treatment <br />eliminates the need for a canopy and <br />sizing standards. <br />resolved the City correction item. <br />EMC 14.40.050.8.12 states: <br />12. Stormwater, surface water, ground water, artesian well <br />water, roof runoff, subsurface drainage, swimming pool <br />drainage, condensate, deionized water, noncontact cooling <br />water, and unpolluted wastewater, unless specifically authorized <br />by the director. <br />The code does not make any reference to a canopy, so there is <br />no code justification for expanding the canopy. It is our <br />understanding that the City is seeking to have storm drainage <br />from fueling islands directed to the sanitary sewer, which is <br />allowed if authorized by the director. Stormwater will flow <br />through a 1,000 gallon OWS prior to discharging to the sanitary <br />sewer, exceeding the minimum City water quality standards. <br />The existing site was permitted by the City, vesting the existing <br />design. There is no Code justification to expand the canopy for <br />only 460 square feet of uncovered fuel island area. <br />City Comment: Stormwater is a prohibited discharge to the <br />sanitary sewer, as mentioned in the previous comments from <br />the City and acknowledged by the designer's response. While the <br />code does not specifically state that the control method to <br />prevent stormwater entry to the sanitary sewer must be a <br />canopy, it is a common method to do so. While the east fuel <br />island (Pacific Pride) has an existing canopy, it is insufficient to <br />mitigate the amount of stormwater entering the sanitary sewer. <br />The 1460 square foot drainage area (concrete pad for the fuel <br />island) that the designer is proposing to be directed to the <br />sanitary sewer must have a mechanism to mitigate the amount <br />of direct stormwater from entering the sanitary sewer. If the <br />designer has another proposal other than a canopy to do this, <br />plans and/or a description of the method must be submitted for <br />it and receive approval. <br />Page 4 of 7 <br />
