Keg Permit - Unless you obtain a permit from the Ames Police Department, you may only tap one beer keg at a time during your party. To obtain a permit you will have to go through a short briefing with the Police Department's Alcohol Enforcement Team. The purpose of the briefing is to provide you with information relating to your legal obligations when making alcohol available to others, and to help you plan for a successful, socially responsible party. There is no charge for a permit. See Chapter 17.27 of the Ames Municipal Code.
