You may dispose of wood or coal ash as garbage, but be sure that they are cold. Wetting ashes down before disposal is strongly recommended. Cold ashes can also be brought to the District Transfer Station for disposal.
In small quantities, ashes from clean wood (woodstoves and fireplaces) are fine to add to a compost pile. Wood ash will raise the pH and add potassium to the pile, but too much ash will reduce pore spaces and make the pile too alkaline.
