The waste management section of settings lets you specify the exact tank types and waste types that you service.
Tank Track gives you ten options by default, as shown.
If you want to remove one or more options from the list, simply mouse over the unwanted option and click the delete icon.
If you want to add one or more options to the list, click the add item button, enter the tank or waste type description, enter a waste code abbreviation using up to 2 characters, and click save changes.
You may add as many tank types and/or waste types as needed.
