Yes, you will be charged $20 each month. A cheaper option for occasional use of the second cart is to purchase the City Blue Bags ($2 each). Another option is to take extra waste (no charge up to 500 lbs. of household trash per month-and can be in multiple trips) to the Concord Turnpike Convenience Center at 2525 Concord Turnpike or the Regional Landfill at 361 Livestock Road in Rustburg. The Center also accepts separated bulk and brushes for free from residents.
