Municipal solid waste is a commodity regulated under the apple maggot quarantine. It is a host medium for apple maggot as it may contain host fruit such as apple, cherry, hawthorn, pear, plum, prune, or quince (WAC 16-470-111). The apple maggot quarantine has two main requirements for the movement of solid waste from cities and towns:
- Waste facilities inside an apple maggot quarantine area cannot ship waste to or through a pest-free area without a special permit.
- Waste facilities in pest-free areas cannot accept waste from apple maggot quarantined areas without a special permit.
The municipal solid waste special permit requires that green waste and solid waste are separated. Solid waste may be transported into the pest-free area, however green waste cannot and must stay in the quarantine area.
