******  Permit fee for the Large Construction General Permit (LCGP) has dropped to $100.  This has happened because there is less than a year left on the current LCGP.  Please contact storm water staff with any questions.

******  Please note that the Cheyenne Office of the DEQ Water Quality Division has moved to a new building.  The new address is below.  All NOIs, NOTAs, NOTs, and other reports should be sent to the address below.  Forms will be updated to reflect the new mailing address as soon as possible.  The WYPDES and storm water permitting staff are located on the 4th floor of the new building (the old 'JC Penney's Building' at 17th and Capitol).  The WYPDES compliance staff are located on the 3rd floor.  Other Water Quality programs will be located on other floors.
