Obtaining Stormwater Construction Permits - City of Longmont

Additional guide: EPA has developed an easy-to-read reference explaining the basic principles of developing and maintaining an effective stormwater pollution prevention plan (SWPPP) and can be used at most construction sites in any state, territory or in Indian country. A customizable SWPPP Template, an Inspection Template, two "model or example" SWPPPs, and other stormwater resources are also available. See www.epa.gov/npdes/swpppguide and the Construction Center at http://www.cicacenter.org/swppp.html. Printed copies of the guide are available from EPA's National Service Center for Environmental Publications, 1-800-490-9198, nscep@bps-lmit.com (document number EPA-833-R-06-004).
