Guam Stormwater Workshop- July 2011
July 27, 28 and 29
Wednesday, Thursday and Friday
Sheraton Laguna Guam Resort
470 Farenholt Avenue, Tamuning, Guam 96913
Overview
What: A free two and a half-day workshop on local and federal stormwater requirements and related issues specific to Guam, sponsored by the US EPA and Guam EPA.
Where: Sheraton Laguna Guam Resort, 
470 Farenholt Avenue, Tamuning, Guam 96913
When: Wednesday, July 27 and Thursday, July 28, 8:30 AM to 5:00 PM,
and Friday, July 29, 8:30 AM – 12:00 PM
Why: To provide an overview of federal and local stormwater requirements and other applicable regulations, and to provide permitting information, and in-field examples of best practices to help contractors and developers through the permitting and compliance process on Guam.
Stormwater runoff occurs when rainwater flows over land and either percolates into the ground or flows to nearby streams and coastal waters. Stormwater runoff can transport pollutants (e.g. sediment, nutrients, and other chemicals) that can negatively affect drinking water aquifers and sensitive aquatic resources like streams and coral reefs.
How: Presenters will describe Guam’s sensitive natural resources, review relevant stormwater regulations, best management practices, and provide information regarding effective best management practices and project design criteria. This information will help contractors and developers understand the stormwater requirements, permitting process, and keys to compliance for projects on Guam.
Who: This workshop is sponsored by the US EPA and Guam EPA and is intended for contractors, developers, government agencies, non-profits, and anyone with an interest in preventing stormwater impacts to Guam’s natural resources.
