. The planting plan for the used oil collection site includes re-planting eight spruce trees currently located along the cast side of the Public Works facility's northwest driveway entrance. The trees would provide screening along the north side of the used oil collection structure facing Ben Franklin Avenue. Seasonal HHW Collcction The proposed seasonal HHW collection site would be similar to the five seasonal sites located and operating elsewhere in the County. The HHW site would operate for one or more one-month periods each year (the Shoreview HHW site operated during May in 2004) on Fridays from 10 am to 6 pm and Saturdays from 9 am to 4 pm. It would contain a concrete pad where HHW is removed from vehicles and technicians would consolidate certain liquid wastes (flammable liquids, used antifreeze) into 55-gallon drums. As with other seasonal sites, all waste collected would be removed from the site at the end ofthe operating day and shipped to the year-round HHW facility located at Bay West, Inc. in St. Paul. Permanent signs would be installed along Highway 96, Hamline Ave., and Ben Franklin A venue for the used oil ard lilter collection facility. Temporary signs would be displayed for the seasonal HHW collection facility only on site operating days during the month of operation and up to one month afterwards. A flyer box would be installed at the used oil site to contain HHW site information. . Assessment of Potential Impacts The used oil collcction facility would include a raised metal grate flooring around the input spout to contain any spilled oil. The HHW site concrete pad is constructed to provide a spill containment volume. At their December 1, 2004 meeting, the Arden Hills Planning Commission requested a letter of support for the combined seasonal HHW and used oil collection facility from the MN Army National Guard. Keith Ferdon, Training Area Coordinator, in a letter datcd December 9,2004, states that the proposed facility "will not hinder nor jeopardize the security of the Arden Hills Army Training Site", but requested the County install appropriate street signage along Hamline and Ben Franklin A venue to assist residents. Since receipt of the letter, the County has installed a "Stop" sign on the Army's south Hamline gate as well as "Stop Ahead" and "Stop" signs where Ben Franklin A venue ends. The County would also install signs stating "Military Vehicles Crossing" on Ben Frarklin Avcnue following construction of the combined seasonal HHW and used oil collection facility. Storm water Runoff The project would increase the impervious surface on the Public Works site by 12,610 square fcet (0.29 acres), including the used oil structure (200 square feet). Stormwaterrunoffwould be directed to an existing storm sewer pipe and then to the existing water quality pond immediately . north across Ben Franklin Avenue. 4
