Details are outlined in the Act 40 Manual p. 126.  You cannot discharge stormwater down the sanitary sewer. Not sure about what permits are required: See page 32 of the Act 40 Manual.  Since you are all plann...

Greetings, Several years ago one of our Honors College students prepared a video on the Tollgate Wetland as an Honors Option project for ENE 483.  I thought this video might be helpful:  https://youtu.be/sKyiMS1a3Bk?si=-HrPHUJlkMPlxYD4 This report is a bit old but will give you some information about the Tollgate project:  http://tc3060.pbworks.com/f/FINAL+RPT+TOLLGATE.pdf Dr. Masten
