Who qualifies for an exemption from the use of clear bags?  Who can use a black bag?

Certain businesses and organizations can request permission to use a black bag. Requests must be sent in a letter to CNWM that details the nature of the business and the types of waste produced. Examples of businesses granted permission include: funeral homes, slaughter houses, hospitals, medical facilities, dental offices and animal hospitals. Black bags are also accepted from international waste sources (such as from ships or planes). Haulers are notified by the customer and/or by CNWM that this permission has been granted.
