There are two dump stations located to the left of the gas pumps in the same parking lot, not where the semis are. To access the dump stations, use the code from the store, which gives you only one minute to open up the sewer line. There is rinse water available, but it is non-potable. The dump stations are located 200 meters west of the Perimeter, specifically at TransCanada #1 & Camp Manitou Road.
