the liquid inside the catch basins for documentation purposes.The sample bottle revealed the liquid inside the stormwater catch basin was a pink automotive fluid that smelled strongly of petroleum products. SWM inspected the stormwater infrastructure downstream of the stormwater catch basin to document how far the spill had traveled.SWM observed that the spill had discharged down to the oil water separator, and the pink liquid was visible in all chambers of the oil water separator(forebay, middle chamber, and afterbay). SWM immediately contacted Nelson Petroleum to clean up the contaminated stormwater infrastructure. Three previous inspections in Year 2022 had revealed similar illicit discharge concerns, including: - September:another catch basin that looked to be full of a brown grease residue,and a fuel pump at the Pacific Pride Fuel Station (a tenant of Nelson Petroleum at this location)was leaking on to the ground. SWM observed a direct discharge to their stormwater system. - March:the catch basin on the west side of their fuel island area appeared oily/greasy with visible staining leading towards the catch basin.When SWM opened the storm drain,they observed that the liquid inside appeared dark as if it was oil.A sample was collected and revealed the liquid inside the stormwater catch basin was a dark black color and had a strong odor of petroleum products. - February: SWM investigated a complaint regarding petroleum contamination to a wetland/greenbelt that several businesses discharge to(including the Nelson Petroleum site). Prior to a field investigation of this water quality complaint, SWM discovered that there had been several instances in the past where petroleum contamination to this wetland/greenbelt had been directly linked to the bulk petroleum distribution site to the west(9826 7th Ave SE- formerly a different owner but presently owned and operated by Nelson Petroleum).Once SWM determined that a likely source of this contamination was the Nelson Petroleum site, SWM conducted a site inspection. Upon investigation,it was discovered that nearly every single stormwater asset on the site was heavily contaminated with petroleum products. Nearly every asset was full of an iridescent pink liquid.SWM immediately informed Nelson Petroleum of the illicit discharges to have them clean up the contaminated stormwater infrastructure. In recent months, the property owner has taken temporary steps to plug the private stormwater system to prevent discharge from leaving the property.The valve closure is a temporary spill containment method as designed.Any modifications of an existing stormwater drainage system must be approved and permitted by the City with a public works permit,which has not been submitted by the applicant. Engineering calculations,overflow,capacity, pumping and containment measures have also not been provided for City review and approval to evaluate the ability to protect the environment from future discharges or potential flooding as a result of the plug. The non-compliant and/or illicit connections associated with the fuel island on the property created or allowed illicit discharges of petroleum products into the stormwater system.The existing conditions, and unpermitted modifications to the Stormwater drainage system, are violations of Everett Municipal Code(EMC) 14.28.120 &14.28.130, 14.28.140,which read: • EMC 14.28.120 Maintenance and operations of private stormwater drainage systems Maintenance of private stormwater drainage systems and infrastructure is required to ensure the ongoing effectiveness of the facilities and the protection of life and property.All private stormwater drainage systems shall be maintained by the owner or operator thereof in a safe and proper operating condition,and in compliance with all applicable requirements of this chapter and regulations and procedures adopted hereunder.The city assumes no responsibility Notice and Order Page 2 of 6
